The present invention relates to the field of pipe jacking construction, and more specifically relates to a crossing protection structure and construction method for pipe jacking to pass through a pipe gallery at a close distance, so as to solve the problems of inconvenient construction, limited protection effect and limited structural stability in related technologies; including: Excavation of force-bearing piles, excavation construction of force-transmitting walls and transverse connecting beams, formation of reinforced concrete overall structures of force-bearing piles, force-transmitting walls and connecting beams, excavation of working pits behind force-transmitting walls, construction of supporting beams, Non-penetrating construction of grout holes, layered backfilling of backfill soil and other construction steps are convenient for construction, good protection effect and stable structure.
Description
technical field [0001] The invention relates to the field of pipe jacking construction, and more particularly relates to a crossing protection structure and a construction method for pipe jacking to pass through a pipe gallery at a short distance. Background technique [0002] Pipe jacking technology is a non-excavation pipe laying construction technology used in municipal construction, which completely solves the problems of damage to urban buildings and road traffic congestion during pipeline burying construction. highlight its advantages. This technology is widely used in the non-excavation laying of various pipelines such as urban underground water supply and drainage pipelines, natural gas and oil pipelines, and communication cables in my country's coastal economically developed areas. In so many pipeline engineering constructions, it is inevitable that the existing construction pipelines pass under or over the existing pipelines and buildings, and the pipe jacking und...
