Construction pipe jacking process of new pipe roofing method

Abstract

The invention discloses a construction pipe jacking process of a new pipe-roofing method. The construction pipe jacking process comprises the following steps that firstly, water level geological investigation is conducted, and monitoring points are arranged; 2, a starting well and a receiving well are made; 3, construction pipe parameters are determined; fourthly, a pilot hole is punched; 5, jacking a wall protecting pipe and installing a steel wire rope; 6, connecting the steel wire rope with the construction pipe; step 7, mounting and debugging; 8, the construction pipe is jacked, and meanwhile the steel wire rope applies pulling force to the front end of the construction pipe; and step 9, obstacle detection. According to the method, ground surface settlement is controlled and observed all the time in the construction process, top deviation in the construction pipe jacking process is effectively reduced, stratum disturbance caused by deviation correction is greatly reduced, and ground surface settlement is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of pipe curtain construction, in particular to a construction pipe jacking process of a new pipe curtain method. Background technique [0002] With the increase of urban space utilization, pipe screen technology is more and more applied to the traffic reconstruction of old urban areas, which realizes the construction without affecting the existing traffic, greatly reduces the impact of construction on people's production and life, and has the advantages of Great application potential. However, due to factors such as equipment, geological conditions, and obstacles during the jacking process of the construction pipe, the construction pipe is easily deflected during the jacking process. At the same time, the existing obstacle detection technology cannot fully grasp the position and size of the obstacle. As a result, it is easy to encounter obstacles during the jacking process of the construction pipe, resultin...

Problems solved by technology

However, due to factors such as equipment, geological conditions, and obstacles during the jacking process of the construction pipe, the construction pipe is easily deflected during the jacking process. At the same time, the existing obstacle detection technology cannot fully grasp the position and size of the obstacle. As a result, it is easy to encounter obstacles during the jacking process of the construction pipe, resulting in the top deviation of the construction pipe. The existing deviation correction technology can easily cause disturbance to the surrounding soil during the deviation correction process, resulting in ground settlement and prolonging the construction period. A series of problems, at the same time, the traditional jacking process, only the starting end of the construction pipe is stressed, which is easy to cause deformation of the construction pipe
