Overlapped shield tunnel house foundation reinforcing structure adjacent to house and construction method

Abstract

The invention discloses an overlapped shield tunnel house foundation reinforcing structure adjacent to a house and a construction method, and relates to the field of tunnel construction. The overlapped shield tunnel house foundation reinforcing structure comprises a house, a municipal main road, a sidewalk, a municipal pipeline, a house foundation grouting area, a preceding shield tunnel, a preceding tunnel deep hole grouting area, a following shield tunnel and a following tunnel deep hole grouting area, wherein the sidewalk is located between the house and the municipal main road, the municipal pipeline is buried below the sidewalk, the house foundation grouting area is located below the sidewalk and is close to the house, the preceding shield tunnel is located below the house foundation grouting area, the preceding tunnel deep hole grouting area is located above the preceding shield tunnel, the following shield tunnel is located above the preceding tunnel deep hole grouting area, the following tunnel deep hole grouting area is located on the periphery of the following shield tunnel, and the preceding shield tunnel and the following shield tunnel are overlapped tunnels. According to the overlapped shield tunnel house foundation reinforcing structure, the problems that in the prior art, construction difficulty and risk are high, control is improper, major accidents such as house inclination and collapse, pipeline damage and road cracking are easy to cause, and extremely severe social influences and economic losses are generated are solved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a building foundation reinforcement structure and a construction method of an overlapping shield tunnel adjacent to a building. Background technique [0002] With the rapid development of the economy and the rapid development of the infrastructure industry, more and more subway plans have been approved, the corresponding subway density is increasing, the construction environment is becoming more and more complex, and the accompanying construction difficulties and risks are increasing. high. In the planning of urban subway lines, factors such as the difficulty of demolition of ground structures and the cost of removing underground obstacles need to be considered. As a result, more and more subway lines have less and less room for selection, and overlapping shield tunnels next to houses often appear , especially the small-radius curves overlapping shield tunnels for avoiding obs...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a superimposed shield tunnel house foundation reinforcement structure and construction method adjacent to the house, so as to solve the difficulties and risks of construction in the prior art and improper control , It is easy to cause major accidents such as house tilting and collapse, pipeline damage, road cracking, etc., resulting in extremely bad social impact and economic loss.
