Manual pipe jacking construction process

Abstract

The invention discloses a manual pipe jacking construction process, and belongs to the technical field of pipe jacking construction. The manual pipe jacking construction process comprises the following steps that S1, construction water and electricity, channels, drainage and lighting equipment are installed, maintenance fences are installed around a working well, and a ladder stand is installed in the working well; and S2, a debugged pipe jacking machine is hoisted into the working well, the pipe jacking machine is placed on a guide rail coated with lubricating oil for accurate positioning, an oil pump is started, a jack is stretched and retracted, and the jack is adjusted until the jack and the back wall meet the jacking requirement. According to the manual pipe jacking construction process, before the construction process, construction preparation is carried out, and during construction, a laser instrument is adopted for measuring the advancing trend of a jacking pipe, so that deviation measurement is carried out, deviation correction can be carried out in time, the quality of a constructed pipeline is improved, and the construction progress is guaranteed; and slag is discharged through a manual trolley, so that soil in the pipeline can be conveniently removed, and harmful gas and dust in the pipeline are discharged, so that the occupational health of workers is ensured.

Description

technical field [0001] The invention relates to the technical field of pipe jacking construction, in particular to an artificial pipe jacking construction technology. Background technique [0002] The artificial pipe jacking construction relies on the thrust of the main jacking cylinder, the pipeline room, the relay room, etc., and adopts the method of manual excavation and excavation to push the tool pipe or roadheader from the working well through the soil layer to the receiving well for lifting. At the same time, the pipeline following the tool pipe or roadheader is buried between the two wells, in order to realize the construction method of laying underground pipelines without excavation. However, the traditional pipe jacking construction technology is extremely difficult during the construction process. It is easy to have a large deviation between the jacking axis and the design axis, which will affect the subsequent use of the pipeline and the construction progress. At...

At the same time, the pipeline following the tool pipe or roadheader is buried between the two wells, in order to realize the construction method of laying underground pipelines without excavation. However, the traditional pipe jacking construction technology is extremely difficult during the construction process. It is easy to have a large deviation between the jacking axis and the design axis, which will affect the subsequent use of the pipeline and the construction progress. At the same time, the construction safety is not good. It is difficult to remove the soil generated during the jacking process, so manual jacking is urgently needed Tube Construction Process
