Abstract

The invention relates to the field of jacking pipe construction, in particular to a penetrating protective structure realizing near-distance downward penetration of a jacking pipe through a pipe rackand a construction method. The structure aims to solve the problems that according to relevant technologies, construction is inconvenient, protective effects are limited and structural stability is limited. The method comprises the steps of conducting stress pile hole digging operation; conducting earth cutting construction of a force transmission wall and a horizontal connecting beam; forming anintegral reinforced concrete structure composed of a stress pipe, the force transmission wall and the horizontal connecting beam; digging a working pit at the rear side of the force transmission wall;conducting construction of a supporting beam; conducting non-penetrating construction on a grouting hole; and conducting layered backfill of backfilled earth. The structure is convenient for construction, stable and good in protective effect.

Description

Technical field [0001] The invention relates to the field of pipe jacking construction, and more specifically to a crossing protection structure and a construction method for a pipe jacking to pass through a pipe gallery at a short distance. Background technique [0002] Pipe jacking technology is a non-excavated pipeline laying construction technology for municipal construction, which completely solves the problems of damage to urban buildings and road traffic jams during pipeline burying facilities. It is in terms of stabilizing soil and environmental protection. Highlight its advantages. This technology is widely used in the trenchless laying of urban underground water supply and drainage pipelines, natural gas and oil pipelines, communication cables and other pipelines in the economically developed coastal areas of my country. With so many pipeline engineering constructions, it is inevitable that existing construction pipelines will pierce or span existing pipelines and buil...
