Construction method of pipe jacking based on whole-process real-time monitoring

Abstract

The invention discloses a pipe pushing construction method based on whole-course real-time monitoring. The method comprises the following steps that (1) a plurality of pipe joints for setting monitoring sections are selected in a pushing direction of pipe pushing, and marked; (2) before the pipe joints needing to be provided with the monitoring sections are put down, strain gauges and collectors are installed on the pipe joints, and the strain gauges are in communication connection with an external control terminal through the collectors; (3) in a pushing process of a pipeline, the collectorscollect strain data on each strain gauge and feeds back the strain data to the external control terminal; and (4) the external control terminal correspondingly adjusts pushing force and grouting parameters according to received real-time data. By adopting the method, the stress change condition of the pipeline in a construction process of pipe pushing is continuously monitored and obtained in realtime in the whole process, the parameters such as the pushing force and a grouting pressure are correspondingly adjusted, such that pipe pushing construction can be smoothly carried out under guidance.

Description

technical field [0001] The invention relates to a pipe jacking construction method. Background technique [0002] With the development of economy and society, there are more and more projects such as underground comprehensive pipe corridors and urban water transmission lines. These projects inevitably cross roads, rivers and existing buildings. If these pipelines laid under the existing facilities adopt a large-area open-cut method, it will not only cause great damage to the existing facilities, but also have a great impact on the environment and traffic. The pipe jacking construction method can well avoid these problems, and the construction speed is fast and the cost is low. The pipe jacking construction mainly refers to setting a jack in the pipe jacking working well 1, and then using a high-pressure oil pump to supply oil to ensure the thrust in the horizontal direction, and push the pipe joints 2 one by one from the starting point to the receiving well 3 at the end poi...

AI Technical Summary

Problems solved by technology

However, due to the complexity of geological conditions, some problems are prone to occur during the pipe jacking construction process, such as the rotation of the machine head and pipe joints during the jacking process, loss of control of the pipe jacking direction, rolling during the jacking process, and surface subsidence, etc. And prior art lacks the pipe jacking construction method that can know above-mentioned situation in time
