Opfindelsen angår en nedløbsbrønd af plast og beregnet til rørsystemer til opsamling af vand, især overfladevand, hvilken nedløbsbrønd omfatter en bunddel, som er forsynet med et indløb og mindst et udløb, samt en ud i et med bunddelen udført 5 topdel med en øvre adgangsåbning, gennem hvilken det rørsystem, hvoraf nedløbsbrønden er en del, kan inspiceres, og hvor bunddelen på i det mindste en del af sin overflade er forsynet med afstivningsribber og eventuelt har et andet indløb.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a plastic drainage well intended for piping systems for collecting water, in particular surface water, said drainage well comprising a bottom portion provided with an inlet and at least one outlet, as well as a top portion formed with a bottom access portion having an upper access opening. through which the pipe system of which the downhole well is a part may be inspected, and wherein the bottom part of at least part of its surface is provided with stiffening ribs and optionally has a second inlet.
Der kendes en nedløbsbrønd af denne art med en bunddel og en 10 topdel, og hvor sidstnævnte er forsynet med korrugeringer. Denne nedløbsbrønd vil, når den nedgraves i jorden i ca. 1,5 m dybde, have tendens til at bryde sammen på grund af det store jordtryk. For at overvinde dette problem kan man fremstille nedløbsbrønden med en større vægtykkelse, hvilket dog er be-15 kosteligt. Under alle omstændigheder må den fremstillingsmetode, som skal anvendes, være meget billig.A downhole well of this kind is known with a bottom part and a top part, and the latter is provided with corrugations. This downhole well, when buried in the soil for approx. 1.5 m depth, tend to collapse due to high soil pressure. In order to overcome this problem one can prepare the downhole well with a larger wall thickness, which is, however, expensive. In any case, the manufacturing method to be used must be very inexpensive.
Fra tysk fremlæggelsesskrift nr. 27 55 176 kendes et renserør, som er forsynet med en topdel i form af en renseskakt. Ud for topdelen findes to afstivningsribber, som strækker sig fra den 20 ene side af topdelen og ned omkring renserøret og op igen på den anden side helt op til topdelen. Disse ribber kan nok give renserøret en vis stivhed, men da de dels er ganske lave, dels ikke strækker sig 360° rundt om renserøret, er deres afstivningseffekt ikke helt tilfredsstillende.From German Patent Specification No. 27 55 176 a cleaning tube is known, which is provided with a top part in the form of a cleaning shaft. Next to the top part are two stiffening ribs which extend from the 20 one side of the top part and down around the cleaning pipe and up again on the other side all the way up to the top part. These ribs may give the cleaning pipe some stiffness, but since they are quite low and do not extend 360 ° around the cleaning pipe, their stiffening effect is not entirely satisfactory.
25 Formålet med opfindelsen er at anvise en nedløbsbrønd af den ovenfor nævnte art, som trods forholdsvis lille vægtykkelse udviser stor stivhed - en stivhed, som er større end hidtil kendt - og, som desuden let kan fremstilles ved rotationsstøbning.The object of the invention is to provide a downhole well of the above-mentioned type which, despite relatively small wall thickness, exhibits high stiffness - a stiffness which is greater than hitherto known - and which can also be easily produced by rotational molding.
30 Nedløbsbrønden ifølge opfindelsen er ejendommelig ved, at en eller flere af de afstivningsribber, der ligger længst væk fra et lodret midterplan gennem nedløbsbrønden, strækker sig 360° DK 167626 B1The downhole well according to the invention is characterized in that one or more of the stiffening ribs located farthest from a vertical center plane through the downhole well extends 360 ° DK 167626 B1

Fra tysk fremlæggelsesskrift nr. 27 55 176 kendes et renserør, som er forsynet med en topdel i form af en renseskakt.

30 Nedløbsbrønden ifølge opfindelsen er ejendommelig ved, at en eller flere af de afstivningsribber, der ligger længst væk fra et lodret midterplan gennem nedløbsbrønden, strækker sig 360° DK 167626 B1 3The downhole well according to the invention is characterized in that one or more of the stiffening ribs located farthest from a vertical median plane through the downhole well extends 360 ° DK 167626 B1 3
Endelig kan ifølge opfindelsen afstivningsribberne udgøres af en lang skruelinieagtig ribbe, der på visse steder har afbrydelser. Derved øges bunddelens stivhed yderligere.Finally, according to the invention, the stiffening ribs may be constituted by a long helical rib having interruptions in certain places. This further increases the stiffness of the bottom part.
Opfindelsen forklares nedenfor under henvisning til tegningen, 5 hvor fig. 1 viser en udførelsesform for en nedløbsbrønd ifølge opfindelsen set i længdesnit, fig. 2 samme set fra oven, fig. 3 samme set i snit efter planen (linien) A i fig. 1, 10 fig. 4 en anden udførelsesform for nedløbsbrønden set fra oven, hvor indløb og udløb danner en vinkel på ca. 135°, og bunddelen er tilsvarende krummet, og fig. 5 en del af væggen i bunddelen, set i tværsnit, hvor den enkelte afstivningsribbe er afgrænset af et stykke af en si-15 nuskurve.The invention is explained below with reference to the drawing, in which fig. 1 is a longitudinal sectional view of an embodiment of a drain well according to the invention; FIG. 2 shows the same from above; FIG. 3 is a sectional view taken along plan (line) A of FIG. 1, 10 FIG. 4 shows another embodiment of the downstream well, wherein inlets and outlets form an angle of approx. 135 ° and the bottom portion is similarly curved, and FIG. 5 is a cross-sectional view of the part of the wall in the bottom part, where the individual stiffening rib is bounded by a piece of a si-15 nose curve.
Den i fig. 1 viste nedløbsbrønd, som er af plast, omfatter en bunddel 1 og en ud i et hermed udformet topdel 2. Bunddelen 1 har et indløb 4, et udløb 5 samt et ind- eller udløb 6. Topdelen 2 har en øvre adgangsåbning 8, gennem hvilken bunddelen 20 l's hulrum 9 kan inspiceres. Bunddelen 1 er som vist forsynet med afstivningsribber 10a, 10b, 10c, lOd, lOe, lOf, 10a't 10b', 10c', 10d', 10e', lOf'. I fig. 1 er ribberne anbragt på ydersiden af bunddelen 1. Der er imidlertid intet i vejen for, at de kunne være anbragt på indersiden eller på både ydersiden 25 og indersiden.The FIG. 1, which is made of plastic, comprises a bottom part 1 and a top part 2 formed therein. The bottom part 1 has an inlet 4, an outlet 5 and an inlet or outlet 6. The top part 2 has an upper access opening 8, through which bottom portion 20 l of cavity 9 can be inspected. The bottom part 1 is, as shown, provided with stiffening ribs 10a, 10b, 10c, 10d, 10e, 10f, 10a't 10b ', 10c', 10d ', 10e', 10f '. In FIG. 1, the ribs are disposed on the outside of the bottom portion 1. However, there is nothing in the way that they could be disposed on the inside or on both the outside 25 and the inside.
Som det særligt tydeligt ses af fig. l og 2 kan bunddelen have et i hovedsagen cylindrisk krummet parti la, på hvis yderside afstivningsribberne befinder sig.As can be seen particularly in FIG. 1 and 2, the bottom portion may have a generally cylindrical curved portion 1a, on the outside of which the stiffening ribs are located.
4 uiv ΐϋ/bZb b i I fig. 2 ses, hvorledes aksen 4a for indløbet 4 og aksen 4b for udløbet 5 kan være sammenfaldende, mens en anden akse 6a for et tredje ind- eller udløb 6 er vinkelret på de sammenfaldende akser 4a og 4b. I fig. 1 ses hvorledes en eller flere af 5 de afstivningsribber lOf, der ligger længst væk fra et lodret midterplan A gennem nedløbsbrønden (planet står i fig. 1 og 2 vinkelret på papirets plan), er ført 360° rundt om bunddelen.4 uiv ΐϋ / bZb b in I fig. 2, it is seen how the axis 4a for the inlet 4 and the axis 4b for the outlet 5 can be coincident, while a second axis 6a for a third inlet or outlet 6 is perpendicular to the coinciding axes 4a and 4b. In FIG. 1, one or more of 5 of the stiffening ribs 10f, located farthest from a vertical center plane A through the downhole well (the plane is shown in Figs. 1 and 2 perpendicular to the plane of the paper), is passed 360 ° around the bottom part.
Man bemærker at indløbet 4 og udløbet 5 er tilvejebragt i en slags muffer på bunddelen. I disse muffer kan de rør, som skal 10 samles ved hjælp af nedløbsbrønden, indskydes, fortrinsvis under brug af en eller flere ikke viste tætningsringe.It is noted that the inlet 4 and the outlet 5 are provided in a type of sleeve on the bottom part. In these sleeves, the pipes to be assembled by means of the downhole well can be inserted, preferably using one or more sealing rings (not shown).
I fig. 1 ses, hvorledes en eller flere af de afstivningsribber 10b, 10c, lOd, lOe, 10b', 10c', 10d', 10e',som befinder sig forholdsvis nær ved det lodrette midterplan A, kan forløbe 15 langs en cirkelbue, som er mindre end 360°. Afstivningsribberne har som vist i fig. 1 i hovedsagen ens afstand, men dette er dog ikke noget absolut forlangende.In FIG. 1 shows how one or more of the stiffening ribs 10b, 10c, 10d, 10e, 10b ', 10c', 10d ', 10e', which are relatively close to the vertical median plane A, can extend 15 along a circular arc which is less than 360 °. The stiffening ribs, as shown in FIG. 1 is essentially the same distance, but this is not an absolute demand.
En eller flere af afstivningsribberne, fortrinsvis de 10a', der befinder sig nær det nævnte lodrette midterplan A, kan som 20 vist i fig. 3 ved den ene eller den anden ende have en retlinet forlængelsesdel 10a^, som mere eller mindre strækker sig ind over topdelen 6. Den nedre forlængelsesdel 10a" er som 25 vist vandret, men for de ribber, der ligger lidt længere hen mod ribben lOf' i fig. 1, kan hver enkelt afstivningsribbe være forsynet med retlinede i hovedsagen lodrette forlængelsesdele. Dog har ribben 10f' som regel ikke nogen retlinede forlængelsesdele. Disse forlængelsesdele bidrager kraftigt til 30 afstivningen af bunddelen.One or more of the stiffening ribs, preferably the 10a 'located near said vertical median plane A, may, as shown in FIG. 3 at one end or the other have a rectilinear extension portion 10a ^ which extends more or less over the top portion 6. The lower extension portion 10a "is, as shown, horizontal, but for the ribs which are slightly further towards the rib 10f In Fig. 1, each stiffening rib may be provided with rectilinear substantially vertical extension members, however, the rib 10f 'generally does not have any rectilinear extension members, these extension members greatly contributing to the stiffening of the bottom member.
Antallet af afstivningsribber kan være et hvilket som helst ønsket, men 10 ribber eller mere er at foretrække.The number of stiffening ribs may be any desired, but 10 or more ribs are preferred.
Som vist i fig. 1 kan den enkelte afstivningsribbe 10a, 10b, 10c, lOd, lOe, lOf, 10a', 10b', 10c', lOd', lOe', 10f' udgøres 35 af en fortykkelse i bunddelen l's væg og have et tværsnit med DK 167626 B1 5 en form som en tandhjul stand. Der er imidlertid intet i vejen for, at den enkelte afstivningsribbe 10 kan have et tværsnit, der er afgrænset af en del af en sinuskurve 15, se fig. 5.As shown in FIG. 1, the individual stiffening ribs 10a, 10b, 10c, 10d, 10e, 10f, 10a ', 10b', 10c ', 10d', 10e ', 10f' can be formed by a thickening in the wall of the bottom part 1 and have a cross section with DK 167626 B1 5 a shape like a cogwheel stand. However, there is nothing in the way of the individual stiffening rib 10 having a cross-section bounded by a portion of a sine curve 15, see FIG. 5th
I fig. 5 ses en anden udførelsesform for nedløbsbrønden ifølge 5 opfindelsen, hvor indløbet 4 og udløbet 5 danner en vinkel v på ca. 135°, og hvor bunddelen l er tilsvarende krummet. Normalt vil vinklen v ligge i intervallet 100 - 170°. Figuren viser, hvorledes afstivningsribberne 20, 20a, 20b, 20c, 20d, 20a' , 20b', 20c', 20d' kan være beliggende i planer med i 10 hovedsagen ens indbyrdes toplansvinkler ai. Eventuelt kan der på den overfladedel lf af bunddelen 1, som er længst væk fra et ydre krumningscentrum C for bunddelen 1, være tilvejebragt et antal hjælperibber 21a, 21b, 21c, 21d, 2le, 21f, 2lg, 21h.In FIG. 5, another embodiment of the downhole well according to the invention is seen, wherein the inlet 4 and the outlet 5 form an angle v of approx. 135 ° and the bottom portion 1 is correspondingly curved. Normally the angle v will be in the range 100 - 170 °. The figure shows how the stiffening ribs 20, 20a, 20b, 20c, 20d, 20a ', 20b', 20c ', 20d' can be located in planes having substantially equal top plane angles ai. Optionally, a plurality of auxiliary ribs 21a, 21b, 21c, 21d, 2le, 21f, 2g, 21h may be provided on the surface portion 1f of the bottom portion furthest from an outer curvature center C of the bottom portion 1.
Som det ses, er disse hjælperibber placeret nogenlunde midt 15 mellem de almindelige afstivningsribber. Deres længde er noget kortere end afstivningsribberne, fordi der ikke er så meget plads til dem, jvf. at afstanden mellem afstandsribbeme 20a, 20b, 20c, osv. på den side af bunddelen, som vender mod krumningscenteret C, er forholdsvis lille.As can be seen, these auxiliary ribs are located approximately mid-15 between the ordinary stiffening ribs. Their length is somewhat shorter than the stiffening ribs because there is not much space for them, cf. the distance between the spacer ribs 20a, 20b, 20c, etc. on the side of the bottom portion facing the center of curvature C is relatively small.
20 I stedet for at afstivningsribberne 10a - lOf og 10a' - 10f' ligger i parallelle planer, således som vist i fig. 1, kan afstivningsribberne udgøres af én lang skruelinieformet ribbe, der på visse steder har afbrydelser. Afbrydelserne findes på de steder, hvor skruelinien skærer topdelen 2.20 Instead of the stiffening ribs 10a-10f and 10a '- 10f' lying in parallel planes, as shown in FIG. 1, the stiffening ribs may be constituted by one long helical rib having interruptions in certain places. The interruptions are found in the places where the helix intersects the top part 2.
25 Der er intet i vejen for at virkemåden af indløbet 4 og udløbet 5 ændres, så at 4 er et udløb og 5 et indløb. Det er også , muligt, at nedløbsbrønden kan være forsynet med en ikke vist muffe forneden i fig. 2, hvilken muffe så tjener som indløb eller udløb alt efter, hvad der er behov for.25 There is nothing in the way of changing the operation of the inlet 4 and the outlet 5 so that 4 is an outlet and 5 is an inlet. It is also possible that the downstream well may be provided with a sleeve not shown below in FIG. 2, which sleeve then serves as an inlet or outlet as required.
30 Nedløbsbrønden ifølge opfindelsen kan anvendes såvel til rørsystemer til opsamling af regnvand (overfladevand) - i hvilket tilfælde rørsystemet og de tilhørende nedløbsbrønde er nedgravet ca. 1,5 m i jorden - som til dybere liggende rørsystemer.The downstream well according to the invention can be used for both pipe systems for collecting rainwater (surface water) - in which case the piping system and the associated downhole wells are buried. 1.5 m into the ground - as for deeper-lying pipe systems.
