Abstract

The shaft is connected to a connection plate (7) which comprises four sides and a cover having an access opening. The plate has a chamber which is large enough for maintenance work to be carried out. The four side walls (1,2,3,4) contain holes for feeding in the cables and pipes. A open cable access is provided on the top of the shaft. The volume of the shaft is at least 2 m<3>.

Description

The invention belongs in the field of development of building plots, that is Civil engineering.

According to the current state of the art for all supply and disposal lines partly in the street body and office, which had previously been filled with frost protection gravel sidewalk - in parallel in their own trenches - dredging - soil removal - lei laying - sanding - refilling - compaction - i.e. with high quality labor, material and cost.

The respective property-house connections are after the main building is installed again with the same effort - each line for itself dredges etc. , , , This results in countless oblique and right-angled crossings pipe systems. To control the sewer lines are in the street rich manholes with manhole covers, asphalted, mortised, in adjusted the correct height to the asphalt and reinstalled.

For the house connection ducts, the pipes and connecting shafts in the Plot created at the applicant's expense. House connections for water, gas or District heating is also separated (mostly by different companies) dredged, tapping slide fitted with telescopic linkage and road cap pro visually offset, exposed during asphalting, aligned and finally flat ben installed. Signs are on to find the sliding caps in winter Posts or house walls required. The connecting lines to the properties are first led into the property 2-3 m and later to the building extended by calling.

The supply cables for telephone, cable TV and electricity will ultimately be in the Be of the sidewalk (if available). In addition the already installed frost protection gravel  again (mostly again by one or two separate companies) dredged, cables laid, sanded in and refilled with frost protection gravel and ver seals.

The invention specified in claim 1 is based on the problem To create manhole, in the work space / interior, the connection points of the House connection lines are freely accessible so that their assembly and repair are strong is simplified, as well as by its predetermined recesses in the side walls to create an inexpensive, clear management of the supply lines. In addition, through this manhole, the currently on private property necessary inspection shafts for the rain and dirty water sewer as well as in Street body currently located slide valve for gas or district heating and water Lines unnecessary and for any repairs at the connection points of the house connections or main lines no road opening necessary and therefore the Road traffic should not be hindered.

This problem is solved in that the revision shaft ( Fig. 1) is designed in a size that it has a work space of about 2 m ³ inside by all main access and house connection lines are freely accessible. This shaft ( Fig. 1) consists of four mutually perpendicular side walls and an upper side, the dimensions of which should be such that a sufficiently large working space is created inside the shaft. The four reinforced concrete shaft walls are slightly inclined outwards for technical reasons (cf. Fig. 2 to 5). The inspection shafts are placed on the corresponding in-situ concrete foundations at a distance of the respective width of the property, at an incline on the slope, on the street, at the correct height.

This means that rainwater and dirty water is freely accessible in the inspection shaft water main and house connection pipes with inspection openings, the water supply supply line with the house connection tapping slide and house connection line, the Natural gas pipeline with the house connection tapping valves and finally the cables for Telephone and TV with the corresponding house connection sleeves.

Only the power supply cables are laid outside the shaft in the area of the predetermined lowering ( 6 ) ( Fig. 1, 2 and 3).

Shaft wall ( 1 ) ( FIGS. 1 and 2) and shaft wall ( 2 ) ( FIGS. 1 and 3) are provided with savings in the planned position, depth and size for carrying out the main supply and disposal lines. The number, position and depth of the recesses can be changed depending on the property and as required.

In the shaft walls ( 3 ) ( Fig. 1 and 4) and ( 4 ) ( Fig. 1 and 5) are also ausear machined from savings in the required number and size and in a planned position and depth to carry out the house connection supply and disposal lines ,

The shaft wall ( 4 ) ( Fig. 1 and 5) is bent upwards so that the shaft cover ( 5 ) ( Fig. 1 and 6) does not protrude into the street area on the one hand and on the other hand the necessary work space inside the shaft remains even with narrow pavement widths.

The manhole cover ( 5 ) ( Fig. 1 and 6) is to be produced in a sufficient compressive strength according to the need for the traffic load.

To enter the inside of the shaft, the shaft cover ( 5 ) ( Fig. 1 and 6) also contains a sufficiently large manhole, which is covered with a manhole cover. Furthermore, the shaft ceiling over the entire width of the shaft includes a depression ( 6 ) ( Fig. 1, 2 and 3) in the necessary width and depth, for the open laying of the required power cables.

To the side of the shaft, in the above-mentioned depression ( 6 ) (Figure and 1, 2 and 3), a continuous insertion slot ( 8 ) ( Fig. 2 and 3) is provided for looping in the telephone and TV cables at the required height , The sockets for house connections are also located inside the shaft. With the exception of the power line, all house connections for supply and disposal lines inside the shaft are freely accessible.

The house connection angle plate ( 7 ) ( Fig. 1 and 7) with passages analogous to the shaft wall ( 4 ) ( Fig. 1 and 5) serves to fix the house connection channels and empty pipes on the property boundary, as well as a supporting wall for the street-side trench backfill on the property side Exposure to create the house connections.

Due to the development of the inspection shaft with a house connection angle plate all supply and disposal lines as well as house connection lines in one ge common trench, the manholes and the gate valve caps for water and gas in the streets are eliminated, the house connection shafts in the building ground pieces are also eliminated. When paving the road, there is no need for manhole covers or gate valve caps are raised or adjusted. By laying the sewer pipes in the sidewalk area are exposed to less stress than in the street area.

The follow-up costs are much lower, as all known weak points, such as the gate valve for water and gas as well as cable sleeves and last but not least the sewage channels in the inspection shaft ( Fig. 1) are freely accessible.

For repairs to main lines, which occur when using the inspection shaft If the road lies underneath the sidewalk, it remains undamaged and passable. Furthermore be no cross lines prevent the excavations.

The saving of the separate excavation represents a significant cost reduction and refills for water, gas, electrical, telephone and TV lines The pension providers reimburse these savings to the development agency. The A main company is responsible for the earthworks and filling and not 3 or 4 companies as before. After all, the construction time is shorter and therefore the financing costs are significantly lower.

The power supply cables are currently still in the area of the shaft lowering laid, led to above-ground, separate house connection PVC distribution boxes and from there the house connections connected.

It is planned to use the area of the manhole cover as a distributor house connection space, ie to seal off the end wall ( 1 ) ( Fig. 1 and 2) and ( 2 ) ( Fig. 1 and 3) and to provide a walk-in cover. Thus, the power supply house connections would be freely accessible to integrate in the shaft system.

When developing a corresponding "built-in distribution cabinet" (instead of hitherto usual above-ground distribution boxes) would also be the electricity House connections in the shaft area made freely accessible. When laying empty pipes from shaft to shaft, this room can be used as a cable duct.

The shafts are planned for a channel depth of 1.50 m to 1.80 m. H. that all ab flow lines of the basement - as in DIN 1986 for drains below the backflow level mandatory - to be initiated via lifting pumps.

For cases where a greater channel depth is required - e.g. B. Overcoming hilltops or for direct cellar drainage - sub-shaft construction parts (= deepening of pages 1-4) are installed with the required heights. Furthermore, the shafts can also be made divisible ( FIGS. 8, 9 and 10). The lower part of the shaft ( Fig. 9 and 10) allows different wall heights and thus variable shaft heights. In the case of separate manufacture of the upper and lower part of the shaft, an offset must be provided to stabilize the two shaft parts lying on top of one another (FIGS . 8, 9 and 10).

If necessary, the shaft or the lower part of the shaft ( Fig. 10) can be provided with a bottom plate ( Fig. 10) in the case of the separate manufacture of upper ( Fig. 8) and lower part ( Fig. 10). The shaft would then be suitable for installation in the groundwater area. Here, the corresponding shaft bushings, shaft lining with a built-in lip seal for the watertight passage of all supply and disposal lines must be provided so that the shaft becomes watertight.

After removal of humus and creation of the street level across the entire width of the street, as well Graveling only one lane area becomes all supply and disposal lines the main lines in the walkway area, parallel to the street (straight or curved) and the house connection lines for the opposite plots, at right angles to the street - in a common mono trench, precisely arranged in position and depth - specified by the corresponding passages in the inspection shaft - one after the other laid and in layers with small-grain, seepable, self-compacting material  filled up to the street level, covered with filter fleece and finally with Frost protection gravel - used to build up the surface (asphalt, pavement, gravel, etc.) crowded.

The inspection shaft, as well as the house connection angle plate with the given Feedthroughs for the supply and disposal lines are each directly on the Property boundary offset so that 1-4 property-house connections are possible. All main and house connection lines are exposed in the inspection shaft Lich.

The sewage pipes are given corresponding inspection openings.

For all house connections for water and gas or district heating only at Erstel appropriate tapping slide installed and the connection cables through the openings in the inspection shaft (or for the opposite Connections through built-in empty pipes with house connection angle plate) directly to Outbuilding led.

The cables for telephone and TV are looped into the inspection shafts ( Fig. 1). The house connection sockets are located in the inspection shaft and the connection cables are routed to the connection buildings as before (via an empty conduit).

The power supply lines are laid through the cable pit ( 6 ) ( Fig. 1, 2 and 3), the corresponding house connections are called and lead to the property (via built-in conduits in the street area) or buildings.

Inspection shaft ( Fig. 1) and angle plate ( Fig. 1 and 7) are stable on cast-in-place foundations, in a precise, planned position, each directly on the sidewalk or roadside and at a precisely planned height after the street top edge. Due to the required slope for the waste disposal line (on level ground), a higher shaft depth is achieved through higher foundations.

The shaft floor between the foundations is up to the lower edge of the revision manhole filled with gravel. This is due to the spaces between the pipe ducts penetrating leachate can seep away. If the soil is not seepable a drainage line is installed below the rainwater canal.  

The supply and disposal lines shown in the following drawings and their location, depth and size correspond to the design and the need a pilot project.

These must therefore be checked according to the object or adapted to the local conditions.
