Description

A commercial concrete integrated septic tank device and its application method

technical field

The invention belongs to the technical field of septic tanks, in particular to a commercial concrete integrated septic tank device and a method for using the same.

Background technique

The septic tank is a device for treating feces and filtering and sedimenting. The solidified matter enters the septic tank and decomposes at the bottom of the pool. The hydrated matter in the upper layer flows away through the pipeline, which can effectively prevent the pipeline from being blocked and give the solidified object enough time to decompose. At present, common septic tanks mainly include concrete septic tanks and glass fiber reinforced plastic septic tanks. The main advantages of glass fiber reinforced plastic septic tanks are small size and good sealing performance when integrated, but their mechanical strength is low and installation is cumbersome. The advantages are large volume, high mechanical strength, and easy installation. However, there are internal chambers in the septic tank. Therefore, it is difficult to remove the inner mold when making an integrally formed septic tank by concrete pouring, so it needs to be produced. The two half-molds form a whole through bonding or installation in the later stage. In this way, the sealing performance is greatly reduced, and the preparation steps are cumbersome, and the mechanical strength is also reduced by the way of assembling multiple half-molds.

The side of the septic tank lower mold 2 is fixedly connected with a second sealing ring 5, and the first sealing ring 4 is provided with several first bolt holes 6, and the second sealing ring 5 is provided with several first bolt holes. Two bolt holes 7, the first bolt hole 6 corresponds to the second bolt hole 7;

Several inner mold bags 8 are arranged between the upper mold 1 of the septic tank and the lower mold 2 of the septic tank, because some septic tanks in actual production have a length of more than ten meters or even longer, which needs to be planned according to the actual production demand. The number of membrane bags, so the number of inner mold bags 8 can be 1, 2, 3, 4, or other numbers of inner membrane bags 8; inner mold bags 8 can use different types of bags according to the usage, such as : air bags can be used to inflate as pouring inner molds; filling bags can be used to fill the bags with water or use sand and other items to fill up, and the filled bags can be used as inner molds; the inner mold bag 8 is provided with There are inlets and outlets 9, and the inlets and outlets 9 correspond to the filling tank 3;

By setting the inner mold bag 8, the defects of large volume, large area occupied and difficult to move and transport of the inner mold are overcome, and the method of splicing the mold in the early stage of pouring is simpler, and the inner mold can be assembled by inflating or filling other fillers. Installed in the steel frame, the production method is simpler, and the demoulding process is also easier. Take out the filler, the inner mold bag 8 shrinks, and the inner mold bag 8 is taken out from the pouring groove 3 to complete the integrated pouring with a high degree of molding. , there is no need for splicing in the later stage, the structure is stronger, and the materials of the present invention can be recycled, saving material costs;

The lower mold 2 of the septic tank is provided with several mounting holes 10, and the outer wall of the lower mold 2 of the septic tank is fixedly connected with several groups of fixing blocks 11, and each group of fixing blocks 11 has two, and each group of two fixing blocks 11 is located on both sides of the mounting hole 10, and the fixing block 11 is provided with a first limiting hole 12;

The mounting hole 10 is provided with a supporting structure 13, the supporting structure 13 includes a main body 14 and an arm 15, the main body 14 is provided with a second limiting hole 16, and the second limiting hole 16 is connected to the first Corresponding to the limit hole 12, the top surface of the main body 14 is rotatably connected with two support arms 15, the angle between the two support arms 15 is α, and the maximum value range of the angle α is [100°, 160° °];

The inner mold bag 8 is supported by setting the support structure 13 to solve the problem that the inner mold bag 8 cannot be poured directly; the two support arms 15 are connected by rotating on the top surface of the main body 14, so that when in use, the two support arms 15 is spread out, and the inner mold bag 8 is placed on the two support arms 15 to complete the support of the inner mold bag 8. When the pouring is completed, the supporting structure 13 needs to be taken out, because the inner mold bag 8 has been taken out before , so drag the support structure 13 outwards, the two arms 15 will be closed, and finally the support structure 13 will be taken out to complete the integrated pouring, avoiding the use of concrete blocks or other objects for support, resulting in the problem that it cannot be taken out later, And then affect the overall strength of the septic tank.

Embodiment 2: As shown in Figures 1-6, the difference between this embodiment and Embodiment 1 is that: the main body 14 is provided with a dredging hole 17, and one end of the dredging hole 17 is provided with a check valve 18, and The return valve 18 is located at one end close to the support arm 15, the check valve 18 can only be opened outwards, and cannot be opened in the dredging hole 17;

Because in the process of pouring concrete, there will be concrete flowing between the two support arms 15, so there will be some difficulty in taking out the support structure 13, and by being provided with a dredging hole 17 in the main body 14, at one end of the dredging hole 17 A check valve 18 is provided to prevent the concrete from clogging the dredging hole 17. When the support structure 13 is difficult to take out, insert an iron rod or the like into the dredging hole 17, push the check valve 18 open, and move the two arms 15 The concrete in between is removed, and the support structure 13 is taken out.

Embodiment 3: As shown in Figures 1-4 and 7-8, the difference between this embodiment and Embodiment 2 is that the main body 14 includes an upper main body 19 and a lower main body 20, and the upper main body 19 and the lower main body 20 threaded connection between them; the lower main body 20 is provided with a second limiting hole 16, which corresponds to the first limiting hole 12, and the top surface of the upper main body 19 is rotatably connected with two The support arm 15, the angle between the two support arms 15 is α, and the maximum value range of the angle α is [100°, 160°]; the upper body 19 and the lower body 20 are provided with dredge holes 17, the two dredging holes 17 are aligned; one end of the dredging hole 17 is provided with a check valve 18, and the check valve 18 is located at one end close to the support arm 15;

Because the supporting structure 13 in embodiment one and embodiment two all can not adjust length, can not meet the task of pouring of different types of septic tanks, because the design concrete cover thickness of different types of septic tanks may be different, this just causes The support structure 13 in Embodiment 1 and Embodiment 2 cannot meet the tasks of pouring different types of septic tanks; and through the screw connection between the upper body 19 and the lower body 20, the length of the support structure 13 can be adjusted by rotating the upper body 19 , and then achieve the purpose of adjusting the thickness of the reinforced concrete cover.
