Rock soil slope anti-blocking forming water seepage drainage pipe

Abstract

The invention relates to the technical field of construction engineering, in particular to a rock soil slope anti-blocking forming water seepage drainage pipe. The drainage pipe comprises a water drainage pipe body; the water drainage pipe body comprises a water seepage section arranged on the inner side of a water stagnation layer and a drainage section arranged on the outer side of the water stagnation layer, water seepage holes are formed in the water seepage section, and an anti-blocking joint is arranged at the end part of the water seepage section; the anti-blocking joint comprises a joint pipe, a rotating shaft, a bearing, stirring blades and a balancing weight; one end of the joint pipe is in communication with the water seepage section and is fixedly connected to the outer wall ofthe water seepage section, and drainage holes are formed in the end surface of the other end of the joint pipe at intervals; the rotating shaft is arranged in the joint pipe, the two ends of the rotating shaft are connected to the inner wall of the joint pipe through bearings, and at least three stirring blades are uniformly distributed on the rotating shaft; and one ends of the stirring blades are fixedly connected to the rotating shaft, and the other ends of the stirring blades are fixedly connected to the balancing weight, and the distance between the balancing weight and the rotating shaft is equal to the distance between the rotating shaft and the end surface, provided with the draining holes, of the joint pipe. The drainage pipe has the advantages of being large in filtering area, high in drainage efficiency, free of blockage and long in service life.

[0002] With the development of urbanization, the urban space is getting smaller and smaller, and the development and utilization of underground space is getting bigger and bigger. The depth of foundation pits in general construction projects exceeds 10m, and the local soil layer contains a large amount of water, which is called perched water , for the excavation and support construction of the foundation pit below the aquifer, the aquifer has a great influence on the stability and safety of the slope and the construction of the basement structure. An important factor for slope landslides is to use ordinary drainage pipes for drainage. When the water in the aquifer is diverted, the particles in the soil will be discharged with the water flow, which will cause the loss of soil particles and affect the safety of the slope. For this reason, the Chinese patent CN202012073U has announced A drainage device for the aquitard of the support surface of a foundation pit, comprising a support surface layer, the outside of the support surface layer is the soil of the aquitard layer, at least one drainage pipe is arranged in the support surface layer, and a part of the drainage pipe is in the For the aquitard soil outside the support surface, at least one drainage pipe is set in the support surface, a part of the drainage pipe is in the aquifer soil outside the support surface, and the other part of the drainage pipe is exposed on the support surface On the inner side of the aquifer layer, water seepage holes are provided around the drainage pipe on the side of the aquifer, and a filter screen is wrapped outside the water seepage hole of the drainage pipe, and a space is left between the filter screen and the soil of the aquifer layer, and the space is filled with There are filter materials, and the disadvantages of the drainage pipe in the above-mentioned patents are: first, the end of the drainage pipe inserted into the aquifer is closed, which reduces the filtration area and reduces the drainage efficiency of the drainage pipe; second, the end of the drainage pipe inserted into the aquifer It is closed, which also reduces the impact of water in the aquifer on the drainpipe and reduces the drainage efficiency of the drainpipe; third, the filter screen is easily blocked during long-term use of the drainpipe, resulting in no drainage; It is the drainage pipe that is easy to wear due to soil quality during long-term use, which reduces the service life of the drainage pipe
