Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, and in particular to an engineering drainage structure. Background Art

[0002] Drain pipes are mainly used for drainage of rainwater, sewage, farmland irrigation and drainage. Drain pipes are divided into plastic drain pipes, concrete pipes and reinforced concrete pipes. Drain pipes are new-type seepage and drainage plastic pipes with a corrugated appearance formed by adding other additives to high-density polyethylene. The permeable corrugated pipe is made by punching holes in the grooves and wrapping the outer periphery of the pipe with needle-punched geotextile. According to the type of corrugated pipe, it can be divided into single-wall permeable corrugated pipe and double-wall permeable corrugated pipe. It, soft permeable pipe and plastic blind ditch have become the three major products in my country's civil engineering construction (seepage, drainage). Depending on the drainage pressure, the municipal drainage network can choose double-arm corrugated pipes and straight-wall pipes. Straight-wall pipes have strong pressure bearing capacity and can be used as special pipes for large-scale drainage and sewage pipe networks.

[0003] Improper construction of drainage pipes and other pipelines may cause damage, which in turn leads to damage to the drainage pipes. Repairing and connecting the damaged pipes is a major problem in pipeline construction. Traditional repair methods are relatively simple and crude, but it is difficult to ensure the tightness of the connection after the pipe repair. In addition, the existing repair devices are generally fixed in length. When replacing or repairing, if there is an error in the size measurement, the probability of successful repair will be greatly reduced.

[0004] To this end, the utility model provides an engineering drainage structure for solving the above-mentioned problems and ensuring the tightness and applicability of pipeline connection. Utility Model Content

[0006] A No. 2 clamping ring is integrally formed on the top peripheral side of the lower connecting pipe, and a No. 2 water-blocking pad is provided on the internal fixing pad of the No. 2 clamping ring.

[0007] Preferably, the cross-section of the clamping ring is L-shaped and connected to the wall of the upper connecting pipe or the wall of the lower connecting pipe.
