Municipal drainage pipe pit groove supporting structure

Abstract

The invention discloses a municipal drainage pipe pit groove supporting structure, and relates to the technical field of pit groove supporting structures. According to the key points of the technicalscheme, the municipal drainage pipe pit groove supporting structure comprises two oppositely-arranged supporting piles, screw rods are rotatably connected into the supporting piles, rotating wheels are fixedly arranged on the screw rods, lifting inserting seats are connected to the screw rods in a threaded mode and slidably arranged in the supporting piles, vertical limiting strips are arranged onthe outer sides of the lifting inserting seats, sliding grooves facing the limiting strips are formed in the supporting piles correspondingly, and the limiting strips are slidably arranged in the sliding grooves; and receding grooves are formed in the limiting strips, inserting blocks are slidably arranged in the receding grooves, compression springs used for jacking the inserting blocks out of the receding grooves are further fixedly arranged in the receding grooves, the other ends of the compression springs are fixedly connected with the inserting blocks, and inserting holes allowing the inserting blocks to penetrate out are formed in the supporting piles correspondingly. The municipal drainage pipe pit groove supporting structure has the effects that the height of the supporting pilescan be adjusted, thus the municipal drainage pipe pit groove supporting structure can be suitable for drainage pipe pit grooves of different depths, and the practicability during using is improved.

Description

technical field [0001] The invention relates to the technical field of pit support structures, more specifically, it relates to a municipal drainage pipe pit support structure. Background technique [0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewer pipes", and are usually called municipal drainage pipes in engineering. According to the current situation of the facilities under the municipal roads in China, different pipelines are generally installed, such as electricity, communication, gas, water supply, drainage pipelines and so on. During the construction of municipal drainage pipelines in cities and towns, problems such as complex engineering geology, small construction area, and short construction period are often encountered. If the construction is carried out according to conventional construction methods, it is difficult to ensure the safety of buildings adjacent to the operation area. [0003] In the...

Problems solved by technology

[0004] However, in the actual use of the support row piles in the above-mentioned patents, the height of the support row piles cannot be adjusted because the support row piles are integrated. When the pit is deep, the relatively fixed support row piles will It is difficult to support and protect the pit at the upper end, so there are certain limitations in use. When the depth of the pit of the drainage pipe is different, different types of supporting piles must be used to protect the pit, which is not convenient to use. Less practical
