Abstract

The invention discloses an arc-shaped pipe jacking construction device. The arc-shaped pipe jacking construction device comprises a tool pipe body. A driving system, a deviation rectifying system, a screw mud conveying system, an electric appliance control system and a hydraulic control system are also arranged in the tool pipe body. The electric appliance control system comprises a programmable interrupt controller (PIC). The programmable interrupt controller (PIC) is connected with a crystal oscillator, a storage battery, a processor, an LED display screen and a tripping device through datalines. The arc-shaped pipe jacking construction method comprises the following steps that S1, foundation pit excavating and processing are carried out, excavating is carried out on a construction site, a foundation pit is excavated, the back of the foundation pit is installed, a muck pool is excavated, the surface of the ground at the bottom of the pit is leveled, guide rails are fixedly installedon the upper portion of the muck pool, and a water stop valve plate is installed in the foundation pit. By means of the arc-shaped pipe jacking construction device, the problems of curved pipe jacking pushing, leakage prevention of pipe joints, uneven stress distribution at curve points of pipe joints and the like can be solved, and the aims of feasible technology, safety and high efficiency areachieved through an actual implementation effect and calculation analysis.

Description

technical field [0001] The invention specifically relates to the technical field of underground construction, in particular to an arc-shaped pipe jacking construction device and a construction method. Background technique [0002] At present, the construction of China's urban rail transit, underground pipe corridors and deep underground flood drainage is in a period of rapid development, but the complex surrounding environment restricts the development and utilization of urban underground space. [0003] In recent years, a new type of trenchless subway station construction technology has been invented abroad, which is the curved pipe jacking technology. The reason why it is called "curve pipe jacking" is that the pipe jacking shell and pipe joints are both arc-shaped, and its propulsion device is also an arc-shaped guide rail with the same curvature radius, which can make the curved pipe jacking and pipe joints along the Propel with a given radius of curvature.
