Description

A temporary diversion device for sewage pipes

technical field

The utility model belongs to the technical field of auxiliary sewage diversion equipment for pipeline construction, in particular to a temporary diversion device for sewage pipes.

Background technique

In water environment management, in order to realize the diversion of rainwater and sewage, intercepting sewage and receiving pipes, and reducing and eliminating the scattered and direct discharge of sewage, a large number of sewage pipe networks need to be built in urban villages. Due to the narrow roadways and many underground pipelines in the urban village, it has brought greater difficulties to the construction, restricted the construction progress and increased investment. For example, in the excavation of the pipe trench, the original confluence pipe was disconnected due to the excavation, causing sewage to be discharged into the trench, resulting in a greater impact on the construction of the new sewage pipe, which is mainly reflected in two aspects: one is the genetic sewage of the pipeline. The immersion bearing capacity is reduced; the second is that the construction of the pipeline foundation is difficult, such as the pouring of the concrete foundation, which is greatly affected. In order to solve this problem, the measures usually taken at present include: 1. Cut off the upstream water, find the upstream sewage well of the confluence pipe, and use a pump to pump the upstream sewage out. However, due to the complexity of urban villages, usually many confluence pipes No sewage wells are built or the interval between sewage wells is far beyond the standard distance, which makes it difficult to implement the pumping and drainage measures or has little meaning after implementation; 2. Build a temporary stagnant pit at the disconnection of the merging pipe, and the sump pit is located in the newly excavated area In the trench, the confluent sewage is pumped out by a pump, and the existing problem is that the stagnant sump occupies the position of the newly-built pipeline, and the pipeline at the sump is difficult to construct. In order to meet the construction requirements of the pipe network and overcome the shortcomings and deficiencies of the aforementioned measures, a temporary diversion facility for sewage pipes is required.

Detailed ways

The utility model is further described below according to the accompanying drawings and embodiments.

As shown in Figures 1 and 2, a temporary diversion device for sewage pipes includes a diversion tube. The diversion tube includes an upstream connecting pipe 8, a reducing pipe 6 and a downstream connecting pipe 7. The upstream connecting pipe 8 and the reducing pipe 6 and the downstream connecting pipe 7 are in fixed communication in turn, the upstream connecting pipe 8 is communicated with the upstream disconnecting pipe 3, and the upstream connecting pipe 8 sets the upstream disconnecting pipe 3 inside, that is, the inner diameter of the upstream connecting pipe 8 is slightly larger than The outer diameter of the upstream disconnecting pipe 3, a moon plate 5 as a blocking port is arranged between the upstream port of the upstream connecting pipe 8 and the upstream disconnecting pipe 3, and the gap between the upstream connecting pipe 8 and the upstream disconnecting pipe 3 is sealed. Block up to prevent sewage from flowing out from the gap between the upstream connecting pipe 8 and the upstream disconnecting pipe 3, which affects the construction of the new pipeline 9; the downstream connecting pipe 7 is connected with the downstream disconnecting pipe 4, and the downstream connecting pipe 7 is set Inside the downstream disconnecting pipe 4, that is, the outer diameter of the downstream connecting pipe 7 is slightly smaller than the inner diameter of the downstream disconnecting pipe 4; the ground on both sides of the pipe trench 10 is provided with support rods 1, and the anti-sling 2 connects the support rod 1 and the flow guide The pipe loop is in the rope loop, the bottom loop surrounded by the anti-sling rope 2 is in contact with the diversion pipe, the top circle surrounded by the anti-sling rope 2 is in contact with the support rod 1, and the anti-sling rope 2 is in contact with the diversion pipe. The pipe plays a supporting role, and on the other hand, the lower inner wall of the upstream connecting pipe 8 at the larger end of the guide pipe can be in close contact with the lower outer wall of the upstream disconnecting pipe 3 .

Further, the support rod 1 is H-shaped steel.

As an improvement of this embodiment, the moon plate 5 is arranged on the upper circumferential side of the upstream disconnecting pipe 3 so that the lower inner wall of the upstream connecting pipe 8 is in close contact with the lower outer wall of the upstream disconnecting pipe 3 . The moon plate 5 and the anti-sling rope 2 work together to make the lower inner wall of the upstream connecting pipe 8 closely contact with the lower outer wall of the upstream disconnecting pipe 3 to avoid the outflow of sewage.

Further, the upstream connecting pipe 8, the reducing pipe 6 and the downstream connecting pipe 7 are all made of steel. The steel material has a better pressure bearing effect, and the effect of resisting the collision of foreign objects during the construction process is better.

Further, the upstream connecting pipe 8, the reducing pipe 6 and the downstream connecting pipe 7 are welded into one in sequence.

Further, the upstream connecting pipe 8 , the reducing pipe 6 and the downstream connecting pipe 7 are integrally formed of plastic materials. The plastic material is lighter than the steel material and is easy to transport.
