Round top pipe correction adjustment pipe

Abstract

The invention discloses a round jacking pipe correction adjusting pipe. Four locating supports A are symmetrically welded to the circumference of the inner wall of the middle section of a steel pipe A at equal intervals, four locating supports B are symmetrically welded to the circumference of the inner wall of the middle section of a steel pipe B at equal intervals, and the two ends of four adjusting screw rods with external threads penetrate through and are screwed in corresponding round holes of the locating supports A and corresponding round holes of the locating supports B respectively. The left end of a rubber sleeve ring is arranged in a groove of the right end of the steel pipe A in a sleeved mode, the right end of the rubber sleeve ring is arranged in a groove of the left end of the steel pipe B in a sleeved mode, and a gap between the steel pipe A and the steel pipe B is 0.1 m. A fixing steel hoop A is arranged on the rubber sleeve ring on the periphery of the groove of the steel pipe A in a sleeved mode, a fixing steel hoop B is arranged on the rubber sleeve ring on the periphery of the groove of the steel pipe B in a sleeved mode, the steel pipe A and the steel pipe B are flexibly connected, the relative rotation of the steel pipe A and the steel pipe B is achieved through the elasticity of the rubber sleeve ring, and thus the forward jacking direction of a jacking pipe is corrected. The round jacking pipe correction adjusting pipe is reasonable in structure and convenient to operate and is used for correcting the forward jacking direction of the jacking pipe in jacking pipe tunnel construction.

Description

technical field [0001] The invention relates to the technical field of underground construction engineering, and more specifically relates to a circular pipe jacking deflection correction adjustment pipe, which is suitable for deflection correction and correction of the pipe jacking direction in the construction of pipe jacking tunnels. Background technique [0002] With the development of urban construction, trenchless technology has been widely used in the development of underground space. How to install and replace urban water supply, drainage, gas and communication facilities under the premise of minimal damage to the urban environment has put forward new requirements for underground engineering construction technology. The pipe jacking construction technology is the 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 p...
