Abstract

The invention discloses combined type steel pipe intermediate jacking station equipment for jacking pipe construction and a construction method. The rear end surface of each front jacking pipe is connected with the front end surface of a corresponding rear jacking pipe, each intermediate jacking station round steel pipe is positioned in the corresponding front jacking pipe and the corresponding rear jacking pipe; a steel ring and annular sealing rings sleeve the outer wall of each intermediate jacking station round steel pipe; a first sealed inflatable bag sleeves the outer wall of each steel ring; a second sealed inflatable bag sleeves the outer wall of each intermediate jacking station round steel pipe and is positioned at the rear of the corresponding first sealed inflatable bag; heavy universal castors are mounted at assigned positions of the outer wall of each intermediate jacking station round steel pipe; fixed pedestals are mounted at assigned positions of the inner wall of each rear jacking pipe; after penetrating through each intermediate jacking station round steel pipe, a corresponding fixing screw is tightened and is propped against the inner wall of the corresponding rear jacking pipe; a jack is mounted on the periphery of the inner wall of the front end of each intermediate jacking station round steel pipe; and jack receiving seats are welded on the inner wall of each front jacking pipe at intervals. The construction method comprises the following steps: (1) mounting the intermediate jacking station equipment; (2) jacking; (3) detaching relevant fixing components of the intermediate jacking station round steel pipes; and (4) pulling out the intermediate jacking station round steel pipes. The combined type steel pipe intermediate jacking station equipment is reasonable in structure, convenient to construct, good in water stopping effect, convenient to assemble and disassemble and low in cost, and is used in jacking construction of long-distance jacking pipes.

Description

technical field [0001] The present invention relates to the technical field of pipe jacking construction, more specifically to a reusable combined steel pipe relay room device for pipe jacking construction, and also to a reusable combined steel pipe relay for pipe jacking construction It is suitable for long-distance and ultra-long-distance pipe jacking construction. Background technique [0002] The pipe jacking construction technology is a non-excavation underground pipeline laying construction technology that uses hydraulic pressure as the power to jack the pipe jacking machine and the pipe joints to be laid underground one by one until the pipe jacking receiving well. It has the advantages of high construction precision, wide application of soil quality, wide range of applicable pipe diameters, low construction cost, and small impact on the surrounding environment. With the acceleration of urbanization in my country, pipe jacking technology is widely used in underground...
