Power communication utility tunnel in easy-to-slide area and construction method thereof

Abstract

The invention relates to a power communication utility tunnel in an easy-to-slide area and a construction method thereof. Cable-stayed ground piles are arranged on the upper parts of the inner ends ofhorizontal ground piles, the included angle between the cable-stayed ground piles and the horizontal ground piles is 60 degrees, bottom reinforcing connecting rods for connecting the cable-stayed ground piles and the horizontal ground piles are arranged on the inner sides of the bottoms of the cable-stayed ground piles and the tops of the inner ends of the horizontal ground piles, the included angle between the bottom reinforcing connecting rods and the cable-stayed ground piles is 60 degrees, the included angle between the bottom reinforcing connecting rods and the horizontal ground piles is60 degrees, and a reinforcing risk-avoiding comprehensive assembly device is arranged in an outer frame of a utility tunnel body. A triangular structure is constructed in the easy-to-slide area, theouter frame of the utility tunnel body is clamped at the inner corner of the triangular structure, the easy-to-slide area is protected and supported by utilizing the stroke of the triangular structure, and the triangular structure and a landslide surface on the outer side form a triangular support surface in an integrated mode, so that the utility tunnel body in the area is not damaged by landslide geological disasters.

Description

technical field [0001] The invention belongs to the field of electric power, and in particular relates to a power communication comprehensive pipe gallery in a landslide-prone area and a construction method thereof. Background technique [0002] The comprehensive pipe gallery is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and The monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure and lifeline to ensure the operation of the city. [0003] The traditional power communication integrated utility tunnel is built in a stable underground structure, and will not be affected by dangerous location factors during operation. Therefore, the structural layout is mostly ...

Problems solved by technology

However, due to the complexity of the urban terrain structure, the laying of many utility corridors may need to go out to the surface and pass through a landslide section for construction work laying and structure, due to the output requirements of the internal lines or pipelines of the comprehensive utility corridor, or Affected by the inherent or reconstruction of the bottom structure of the geological work surface, or by the influence of distance factors, the laying work surface of some comprehensive pipe corridors can only be controlled at specific slope topographic positions with landslide risks. When working in the corridor, the traditional pipe gallery structure is difficult to guarantee the safety of the comprehensive pipe gallery after the completion of the later laying
