Anti-leakage and easy-to-replace drainage pipeline

Abstract

The invention belongs to the technical field of drainage pipes, and particularly relates to an anti-leakage and easy-to-replace drainage pipeline. The anti-leakage and easy-to-replace drainage pipeline comprises a pipe body with a cylindrical shape, the pipeline body is formed by splicing an upper half shell and a lower half shell, at least one upper concave part is arranged at the two ends of theupper half shell in the radial direction, the upper concave parts are in a step shape, each upper concave part comprises a first groove and a second groove, the two ends of the lower half shell are provided with lower concave parts matched with the first grooves and convex parts matched with the second grooves, the first grooves and the lower concave parts are spliced to form first sealing grooves, and first sealing strips are arranged in the first sealing grooves. The leak-proof and easy-to-replace drainage pipeline has a good anti-leakage effect, can prevent the pavement from sinking, prevents the sewage from polluting the environment, and has a long service life.

Description

technical field [0001] The invention belongs to the technical field of drainage pipes, in particular to an anti-leakage and easy-to-replace drainage pipe. Background technique [0002] Municipal engineering generally belongs to the country's infrastructure construction, which refers to the infrastructure construction of various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting in urban construction, and is an indispensable material for urban survival and development. The foundation is the basic condition for improving people's living standards and opening up to the outside world. Nowadays, in the actual operation of the drainage pipes on both sides of the municipal roads, factories and residential areas, due to the different water consumption in different time periods, the pressure in the pipes is not high and the flow rate is low during the low peak period when the water consumption is less. The sewage...

Problems solved by technology

[0004] However, this invention uses waterproof materials to smear the joints of the upper and lower half shells. When the upper and lower half shells are assembled, the waterproof coating is easily scraped off, and the sealing of the drainage pipes is poor. Leakage will cause road surface damage. Subsidence will pollute the soil and groundwater on both sides of the pipeline, and at the same time lead to a serious reduction in the service life of the pipeline

In addition, it should be noted that although the anti-corrosion layer coated on the inner wall of the pipeline can play a certain anti-leakage effect, the anti-corrosion layer will be scraped off by the particulate matter in the sewage. Therefore, the drainage pipe of the invention is sealed Poor sex
