Socket shield machine construction method

Abstract

The invention discloses a pipe section shield machine construction method, the steps are: preparing an integral pipe section with long and short axes in section; the shield machine pushes out the opening of the working well, and the first section of pipe with the front end sleeved with a steel collar is installed at the opening. to complete the installation of the first section; transport the second pipe section horizontally to the operation compartment at the tail of the shield machine; first rotate the pipe section 90 degrees around the Z axis and then 90 degrees around the X axis by the manipulator; use a spacer Raise the pipe joint to the required height, and then use the pipe joint laying cylinder to install it into the steel collar of the first pipe joint; then transport, rotate, and raise the pipe joint one by one according to the above method, and then lay the oil cylinder by the pipe joint Connect the next section with the installed pipe section one by one to complete the pipeline laying. Compared with ordinary shield construction, the present invention uses integral pipe joints to overcome the shortcomings of segment seam leakage, save many accessories and auxiliary materials, enhance structural stability, speed up installation, shorten construction period, and reduce costs. Good sealing performance, suitable for a wide range of soil quality.

Description

technical field [0001] The invention relates to a pipe joint shield machine construction method, and belongs to the construction technical field of non-excavation laying of underground pipelines. Its applicable caliber should generally refer to the laying of medium and large underground pipelines where people can carry out construction operations in the pipe. Background technique [0002] At present, there are two construction methods for non-excavation laying of underground pipelines for medium and large pipelines: one is called the pipe jacking construction method, and the other is called the shield tunneling method. [0003] The pipe jacking construction method is a construction method for laying underground pipelines without excavation, and the equipment required for it is generally composed of figure 1 The seven major components shown are: 1---receiving well, 2---pipe jacking machine, 3---subsequent pipe, 4---working well, 5---foundation pit guide rail, 6---bearing Pr...
