(Summary description)In today's daily life, there are many applications of pipelines, such as surface water pipelines, gas pipelines and many other areas. While paving the pipeline, it has always encountered various problems, such as complicated landforms, etc. However, the pipeline routes are all designed well in advance, and the situation of temporary rerouting is not common, so this problem is still to be dealt with. The pipe jacking machine is a very easy-to-use special tool for developing and designing pipelines. It can also handle a variety of complicated underground conditions in consideration of underground foundation pit excavation. Due to its excellent characteristics, the pipe jacking machine has been applied to many pipeline foundation pit excavation projects, and the pipe jacking machine is easy to operate and convenient for maintenance. It has already become many large, medium and small non-excavation roofs. Special tools for engineering projects. The pipe jacking construction of the pipe jacking machine is an underground construction, and the underground conditions change, and the transformation of geology is very easy to cause full expansion, and it is also very easy to cause the pipe jacking machine section to be destroyed. The key drag reduction countermeasure for the pipe jacking construction of the pipe jacking machine is to inject thixotropic mud along the pipeline during the whole process of jacking. If the thixotropic mud injection is not ideal, it will cause excessive force and damage the pipeline. To prevent unsuccessful pipe jacking work caused by improper operation, the following needs to be done: (1) During the whole process of the jacking machine, the thixotropic mud injection should be controlled to ensure that the mud injection has the drag reduction effect and the jacking force is controlled within a certain range. (2) Before the construction of the pipe jacking jacking project, do a good job of surveying the geological conditions of the jacking line. In addition to mastering the engineering survey materials presented by the design plan, the construction company must also encrypt its own data for exploration to ensure a bright future before opening the roof. , Can greatly reduce the occurrence of problems. (3) The pipe jacking machine must be operated during the whole process of jacking, and the large viewing angle correction device should be minimized to make the pipe jacking as smooth as possible. This stipulates that the actual operators of machinery and equipment strictly follow the operating procedures and have excellent actual operating work experience. As a pipe jacking engineering team with extraordinary work experience, it is not too difficult to guarantee.
