Abstract

The application provides a pipeline elevation control device and method, which belong to the technical field of pipeline construction. The pipeline elevation control device includes: a pipeline limiting plate, which is set on the underground dragging pipeline, and is used to limit the dragging track of the pipeline; a support frame, the lower end of which is connected to the pipeline limiting plate, and the upper end is fixed on the ground. A pipeline elevation control method, the steps include: step 1, obtaining construction data and at least two construction well positions; step 2, excavating a foundation pit at the construction well position, and setting a protective structure in the foundation pit; step 3, drilling , and clean up the mud; Step 4, hoist the two pipeline elevation control devices into two construction well positions respectively, adjust the elevation of the pipeline elevation control devices and fix their positions; Step 5, drag the pipeline for construction. In this application, the pipeline elevation control device is used to control and limit the elevation of the pipeline, so as to ensure the effective length of the pipeline underground and avoid the bending problem of the pipeline.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and specifically relates to a device and method for controlling the elevation of pipelines during construction in a sandbar area, so as to realize the control of the elevation of the pipe end of the straight section during the dragging process of the pipeline and ensure the effective length of the pipe end of the straight section. Background technique [0002] With the rapid development of urbanization, the number of buildings and roads in the city increases, and the number of urban underground pipelines also increases. As a result, during the construction process, the construction site is very limited or even smaller. Therefore, during the construction process, the process of open excavation will have a greater impact on the original underground pipelines, traffic and environment of the city. The difficulty of open excavation continues to increase, and even seriously limits the layi...
