The status quo of pipeline construction is accompanied by the modernization of the country. The pace of urban construction is getting faster and faster. Various pipelines are criss-crossed in the underground, and there are more and more buildings on the ground. Excavation construction of open troughs shortens the service life of roads, affects the lives of nearby residents, and damages the surrounding environment, causing inconvenience to people's lives and work. When the pipeline is built to a deeper position, even a wide construction site will increase the construction difficulty and increase the capital investment.
In order to solve the contradiction between the existing municipal facilities and the proposed pipeline construction, as well as the special situation of the pipeline itself, the non-excavation construction technology has gradually emerged in China.
Non-excavation construction technology has been widely used in municipal water supply and drainage projects, power pipeline projects, and prestressed tensile construction of bridges. Now there are many forms of non-excavation construction technology such as shield, pipe jacking, and drawing pipe.
Let's explore the construction technology and application of the pipe.
Overview of Pulling Pipe Construction Technology Equipment This equipment mainly includes DE underground positioning system and horizontal directional drilling (HDD) equipment. The underground positioning system is further divided into an aerial part and an underground part. The sensor in the underground part consists of a carbon rod (signal transmitter) and a probe box, and the signal receiving equipment of the ground part is divided into a guide and a remote sensor.
The horizontal directional drilling (HDD) equipment, that is, the power part of the drawing tube construction, provides propulsion power during the guiding period, and provides pulling force during the construction of the hole making, the hole forming and the drawing tube. Therefore, the fixing of the power equipment is very important.
