An underground integrated pipe gallery structure with anti-liquefaction and anti-floating and application method thereof

Abstract

The invention relates to a liquefaction-resistant and anti-floating underground integrated pipe gallery structure and an application method thereof, belonging to the technical field of integrated pipe gallery. The anti-liquefaction and anti-floating underground integrated pipe gallery structure includes a square tubular integrated pipe gallery body, a filter water absorption mechanism, a cooling mechanism and an air jet mechanism. The upper surface of the integrated pipe gallery body is embedded with a pore pressure sensor, and the filter water absorption mechanism is arranged in the integrated pipe gallery. On the side wall of the pipe gallery body, the cooling mechanism is arranged on the side wall of the integrated pipe gallery body, and the air jet mechanism is arranged on the top of the integrated pipe gallery body. In the liquefaction-resistant and anti-floating underground integrated pipe gallery structure of the present invention, the pore pressure sensor can quickly detect the change of the water content of the surrounding soil during an earthquake. It can reduce the water content of the soil and consolidate the surrounding sand, reducing the conditions for the liquefaction of the soil, thereby preventing the floating of the integrated pipe gallery.

Description

technical field [0001] The invention relates to a liquefaction-resistant and anti-floating underground integrated pipe gallery structure and an application method thereof, belonging to the technical field of integrated pipe gallery. Background technique [0002] The underground comprehensive pipe gallery integrates various municipal engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, and has special inspection ports, hoisting ports and monitoring systems. It is an important infrastructure to ensure urban operation and "" aorta". The underground integrated pipe gallery system not only solves the problem of urban traffic congestion, but also greatly facilitates the maintenance and repair of municipal facilities such as electricity, communication, gas, water supply and drainage, and avoids the frequent digging of roads due to laying and repairing underground pipelines. Influence and interference, reduce the cost of repeated paveme...

AI Technical Summary

Problems solved by technology

Under the action of earthquake load, the saturated sand layer is prone to liquefaction, which leads to the floating of the comprehensive pipe gallery, causing serious economic and property losses

Traditional anti-liquefaction treatment methods are not completely suitable for narrow and long underground pipe galleries. Although researchers have studied many methods and measures to prevent soil liquefaction and comprehensive pipe gallery anti-floating, they are rarely used in actual engineering. A comprehensive pipe gallery structure that can be more suitable in liquefiable soil

[0004] Based on the conventional underground comprehensive pipe gallery, it is impossible to realize independent anti-liquefaction and anti-floating
