Underground pipeline groove support and monitoring integrated structure and construction method

Abstract

The invention belongs to the technical field of municipal administration and constructional engineering, and particularly relates to an underground pipeline groove support and monitoring integrated structure and a construction method. The underground pipeline groove support and monitoring integrated structure comprises a pressure bearing air bag which is a cube, an underground pipeline groove is filled with the pressure bearing air bag, and the upper surface of the pressure bearing air bag is provided with an air inlet valve, an air outlet valve and a pressure meter which communicate with thepressure bearing air bag. The underground pipeline groove support and monitoring integrated structure and the construction method have the following beneficial effects that firstly, the structure is simple, installation through large equipment is not needed, and the advantages of the low construction cost and high construction speed are achieved; secondly, the air inlet valve can be inflated according to changes of the pressure meter pressure value, and the support force can be rapidly adjusted; thirdly, a support structure and a monitoring facility are integrated; and fourthly, multi-time repeated usage can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of municipal administration and construction engineering, and particularly relates to an integrated structure and construction method for underground pipeline trench support and monitoring. Background technique [0002] Under complicated geological conditions, the trench excavation of underground pipelines without grading generally requires the use of wood piles or steel sheet piles for support, and supporting monitoring facilities such as deformation measuring points and internal support axial force measuring points. Both wood plank piles and steel sheet piles need to be driven by large-scale equipment. They must have site conditions for construction equipment operation, high construction costs and long construction period; the supporting structure and monitoring facilities are separated, and the force and deformation of the trench cannot be grasped in real time ; At the same time, once the groove is deformed, m...

AI Technical Summary

Problems solved by technology

Both wooden sheet piles and steel sheet piles need to be driven by large-scale equipment, and the site conditions for construction equipment operation are required. The construction cost is high and the construction period is long; the support structure and monitoring facilities are separated, and the force and deformation of the trench cannot be grasped in real time ; At the same time, once the groove deforms, it is impossible to quickly take measures to increase the support force
