Bunched pipe curtain structure and construction method thereof

Abstract

The invention relates to a bunched pipe curtain structure. The bunched pipe curtain structure comprises a plurality of working pipe sections, a plurality of pipe-jacking pipe sections, prestressed pipelines, prestressed tendons, first concrete structures, second concrete structures, cement paste structures and third concrete structures, wherein first through holes are formed in every two adjacentside faces of the working pipe sections, two partition plates partition each working pipe section into a first area and a second area which are adjacent to the corresponding pipe-jacking pipe section,and a third area is defined by the two partition plates and the inner wall of each working pipe section; second through holes are formed in every two opposite side faces of the pipe-jacking pipe sections; the prestressed pipelines penetrate through the first through holes and the second through holes; the prestressed tendons are arranged in the prestressed pipelines in a penetrating mode; the first concrete structures are formed by pouring concrete in the pipe-jacking pipe sections, the first areas and the second areas; the second concrete structures are formed by pouring concrete between theadjacent pipe-jacking pipe sections or between each working pipe section and the corresponding pipe-jacking pipe section which are adjacent; the cement paste structure is formed by pouring cement paste into the prestressed pipelines; and the third concrete structures are formed by pouring concrete into the third areas. The overall stress performance of the bunched pipe curtain structure is improved, and a temporary support does not need to be additionally arranged during construction.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a bundled pipe curtain structure and a construction method thereof. Background technique [0002] The rapid development of the city has led to an increase in the scale of buildings and population, and a series of "urban problems" such as crowded building spaces, traffic congestion, and backward infrastructure have emerged. The urban underground space has been widely developed and utilized in the sustainable development of the city because of its remarkable land-saving feature, which greatly expands the living space of human beings. As a method of underground excavation, the pipe-curtain method does not need to lower the groundwater level during construction, does not affect the normal use of ground and shallow underground facilities such as roads and pipelines, has low requirements for construction space, and has low noise and vibration pollution. widely used outside.
