Large plastic inspection well

Abstract

The invention relates to a drainage facility, and specially aims to provide a large plastic inspection well with reliable performance. The large plastic inspection well comprises an integral body, wherein the integral body is formed in an injection molding way, the integral body comprises an inspection port and a pipe connecting port, the inspection port is used for overhauling, the pipe connecting port is connected with a pipe, cavities of the body between the inspection port and the pipe connecting port are communicated, the outer wall of the integral body is integrally processed with reinforcing ribs in the injection molding way, the reinforcing ribs comprise vertical ribs and staggering ribs, the vertical ribs are arranged on the middle part and upper part of the integral body, the staggering ribs are staggered on the lower part and bottom of the integral body, and the surface of each vertical rib is smooth. Compared with the reinforced concrete inspection well or the brick inspection well, the large plastic inspection well has the advantages that the capability of resisting acid corrosion, alkaline corrosion and salt corrosion is realized, the large plastic inspection well is suitable for multiple geological conditions, the earthquake proofing performance is high, and the service life is long; the large plastic inspection well can be assembled on site or the finished large plastic inspection well can be directly hoisted, so the construction period is greatly shortened, the construction cost is reduced, the price-performance ratio is high, and the economy is high; the durability of the large plastic inspection well is high; and the problem of difficult popularization and application of the large plastic inspection well in practices is solved.

Description

technical field [0001] The invention relates to water supply and drainage facilities, in particular to inspection wells for maintenance pipelines. Background technique [0002] The inspection well is an underground facility that is convenient for construction in the water supply and drainage project, and is convenient for installing or maintaining the water supply and drainage pipeline after the completion of the project. In the prior art, large-diameter water supply and drainage pipes have already appeared, including those made of metal materials, synthetic materials such as plastics, or prefabricated reinforced concrete. The maximum diameter has reached 2.6m. But the supporting inspection well has not yet been prefabricated with metal, plastic or reinforced concrete; it can only be cast on site or bricked with reinforced concrete. Moreover, due to the frequent entry and exit of personnel in the inspection well, the structural strength requirements are also higher. It fu...

Problems solved by technology

[0003] However, the existing brick or concrete inspection wells buried in the ground are easily corroded and peeled off by wet soil, water vapor, moisture immersion, acid-base salt erosion, and lose waterproof ability, and are easy to infiltrate, resulting in water pollution inside or outside the pipeline.

And the strength is reduced, easy to damage

Since inspection wells are usually set along both sides of the road, once such inspection wells are damaged, not only will the water supply pipes be stopped for maintenance, or the drainage pipes cannot drain, causing drainage paralysis; it will bring inconvenience to production and life; it will also affect the smooth flow of urban road traffic.

Moreover, a large number of clay bricks are used to cause waste of clay resources. The production of bricks and cement itself is also a high-energy-consuming industry. The large-scale use of bricks and cement does not conform to the development trend of energy conservation and environmental protection.
