Description

Prefabricated assembly type reinforced concrete sewage streetwork reserved well

Technical Field

The utility model belongs to the technical field of municipal drainage pipe network engineering, a prefabricated assembled reinforced concrete sewage street shop reserves well.

Background

The urban domestic sewage generally enters a municipal sewage pipe network through a reserved well in a street, and is transferred to a municipal sewage plant to complete purification treatment. The street reserve well is a connecting link of a parcel sewage pipe and a municipal sewage pipe, and plays a vital role in a sewage pipe network system. In specific engineering construction, municipal sewage pipe network construction is generally developed before plots, namely, a reserved well in a street workshop is used firstly, and then a plot sewage outlet pipe is used. Due to the influence of factors such as the building layout in the plot, the height difference of the terrain and the like, the uncertainty of the angle and the elevation of the plot sewage outlet pipe entering the reserved well often causes the problem that an inspection well or a reserved well in a street is required to be additionally built to meet the requirement of the position of the plot sewage outlet pipe entering, so that the construction investment is wasted.

The sewage street reserved well in the prior art mainly comprises three methods of brick laying, reinforced concrete cast-in-place and reinforced concrete prefabricated assembly. The bricked reserved well is low in construction cost and easy to remove, can better adapt to the transformation requirement when the land sewage pipe is connected, but is poor in integrity and seepage resistance, easy to cause sewage leakage and pollute underground water, and is gradually eliminated; the cast-in-place reinforced concrete well has good integrity and strong seepage-proofing capability, but has poor adaptability to the requirement of the access angle of the sewage outlet pipe of the land, and the subsequent transformation is difficult to implement, thus easily causing construction investment waste; the prefabricated assembled well of reinforced concrete construction is fast, the anti-seepage performance is good, but the construction of the prefabricated assembled well of tradition is concerned with more and reserves the well swift and convenient, go out the country sewage to manage, connect out the preformed hole of pipe and establish on same module, lead then reserve the well and to the country sewage to go out the household pipe access angle of family and elevation adaptability poor, and each assembly intermodule concreties completely, when the country sewage goes out the household pipe and connects, the pin-connected panel reserve well exists and demolishs inconveniently, need abolish the reconstruction even.

Therefore, the three methods for reserving the well in the sewage street in the prior art have the common defects that: after the building, the flexible adjustment can not be carried out according to the requirements of the access angle and the elevation of the sewage outlet pipe of the later-stage plot, so that the engineering waste is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a well is reserved in prefabricated assembled reinforced concrete sewage street, solve the weak point that above-mentioned prior art exists, can require to go up and down to reserve the well and carry out the adjustment of elevation and angle to parcel sewage pipe preformed hole after building by laying bricks or stones according to the parcel later stage, can adapt to parcel sewage pipe access direction and elevation demand of leaving household, compromise the wholeness again strong, the advantage that barrier propterty is high, and assembled reinforced concrete well green is energy-conserving, site operation simple to operate is swift, do not increase the engineering cost.

The technical scheme of the utility model:

the well cover comprises a well cover body, a well ring, a shaft adjusting module, a well cover plate, a well chamber upper portion adjusting module, a well chamber reserved sewage outlet pipe access hole module, a well chamber outlet pipe module, a reinforced concrete bottom plate, a concrete cushion layer, an outlet pipe and a ladder stand, wherein the well cover body is located on the prefabricated well ring. Except the well cover and the reinforced concrete bottom plate, the well ring, the shaft adjusting module, the well cover plate, the well chamber upper adjusting module, the well chamber reserved sewage outlet pipe access hole module and the well chamber water outlet pipe module are all prefabricated reinforced concrete modules which are connected through a meshing piece; the reserved well chamber consists of three sections, namely a well chamber upper part adjusting module, a well chamber reserved sewage outlet pipe access hole module and a well chamber outlet pipe module; the prefabricated well ring is sequentially provided with a prefabricated shaft, a prefabricated well cover plate, a well chamber upper part adjusting module, a well chamber reserved sewage outlet pipe access hole module, a well chamber outlet pipe module, a reinforced concrete bottom plate and a concrete cushion layer from top to bottom; hoisting holes are formed in the outer walls of the walling crib, the shaft adjusting module, the well cover plate, the well chamber upper portion adjusting module and the well chamber reserved sewage outlet pipe inlet hole module, and crawling ladders are arranged on the inner walls of the well chamber reserved sewage outlet pipe inlet hole module; when the building is built for the first time, except that the concrete cushion layer, the reinforced concrete bottom plate and the well chamber water outlet pipe module are formed by completely solidifying cement mortar, the other modules are connected through the occlusion piece and are not completely solidified, when the parcel sewage outlet pipe is connected into the well chamber, the reserved sewage outlet pipe in the reserved well chamber is detached to be connected into the hole module and the above parts, the position of the reserved sewage outlet pipe in the well chamber is adjusted to be connected into the hole, the parcel sewage outlet pipe is vertically connected into the hole module, the upper module is assembled again, and waterproof mortar is completely solidified between the occlusion pieces.

Furthermore, a plug is arranged outside the hoisting hole, so that silt is prevented from entering the hoisting hole.

Furthermore, a sewage outlet pipe is reserved in the well chamber and connected into the hole module, and the reserved hole is plugged by adopting an easily-broken material, such as low-grade plain concrete.

Furthermore, the sewage outlet pipe is reserved in the well chamber and connected with the crawling ladder inside the hole module, and three groups of crawling ladder installation reserved holes are arranged in other areas except the reserved hole area. After the plot sewage outlet pipe is connected, the crawling ladder is detached and installed on a reserved hole of the appropriate crawling ladder again, so that the crawling ladder is basically in line with the crawling ladder of the upper module and the lower module.

The utility model has the advantages that: the prefabricated reinforced concrete well is used as a block reserved well, and the block sewage pipe access direction does not need to be considered during municipal pipe network construction, so that the construction difficulty is reduced. When the sewage outlet pipe in the subsequent land is implemented, the reserved holes can be flexibly adjusted, the requirements of the access angle and the elevation of the sewage outlet pipe in the land are met, and the condition that the whole body needs to be dismantled or an inspection well needs to be additionally built in front of the reserved well when the reserved holes do not meet the requirements of the access pipe like a cast-in-place reinforced concrete well is avoided. The prefabricated reinforced concrete well has the advantages of wide applicability, good integrity, strong seepage resistance, greenness, low carbon, energy conservation, environmental protection and low manufacturing cost, is suitable for a sewage reserved well and a rainwater reserved well, and has strong popularization value.
