Mechanical pipe jacking construction technology

Abstract

The invention relates to the technical field of pipe jacking construction, and aims to provide mechanical pipe jacking construction technology, which includes lofting review; well construction; pipe jacking equipment and ground auxiliary facilities installation; pipe jacking equipment out of the working well; console preset jacking axis, The positional relationship between the head of the pipe jacking equipment and the jacking axis is displayed in the form of laser points. At the same time, the application background is equipped with a three-dimensional simulation model for simulating the construction process of pipe jacking; the application background obtains the construction process data of the console in real time, and input In the three-dimensional simulation model, the three-dimensional simulation model controls the background alarm; the operator adjusts the position of the head of the pipe jacking equipment until the position deviation between the laser point and the jacking axis is less than or equal to the preset value; Receiving well; jacking and unearthed. The invention has the effect of assisting operators in finding out the running direction of the machine head and adjusting the running direction of the machine head in time, so as to reduce the situation that the construction quality is affected by human errors during construction.

Description

technical field [0001] The invention relates to the technical field of pipe jacking construction, in particular to a mechanical pipe jacking construction technique. Background technique [0002] At present, the pipe jacking construction is a pipeline burial construction technology with no or less excavation. It excavates the working well and the receiving well, and in the working well, the jacking force generated by the jacking equipment is used to overcome the friction between the pipeline and the surrounding soil. Force, jack the pipeline into the receiving well according to the designed slope, and transport the earth away. After a section of the pipe has been pushed into the soil layer, the second section of the pipe will continue to be pushed in. Pipe jacking construction relies on the thrust of the main jacking oil cylinder and the relay room between pipes, etc., to push the tool pipe or roadheader from the working well through the soil layer to the receiving well, and...

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: during pipe jacking construction, generally a professionally trained operator operates outside the ground control room and carefully detects the entire operating system, observes the earth pressure, oil pressure, The position of the laser beam has high professional requirements for operators, and the degree of dependence on operators during construction requires operators to always check the running direction of the machine head and adjust the running direction of the machine head in time, which is prone to human error during construction Construction Quality
