Pipeline sedimentation automatic control support for urban comprehensive pipe gallery

Abstract

The invention discloses a pipeline sedimentation automatic control support for an urban comprehensive pipe gallery. The support comprises an elevator, an elevator bracket, a pressure bearing plate mounting device, a pressure bearing plate, a pressure bearing foundation and a pressure sensor; the support judges the sedimentation condition between supporting bases of pipelines through a method of using the pressure sensor for monitoring the pressure of a support base, the elevator which is automatically controlled is used for lifting or lowering the pipeline at the sedimentation portion, the steel plate mounting device is used for inserting the pressure bearing steel plate into the position below the lifting bracket to bear pressure, and therefore the aim of changing the height of the support of the pipeline at the portion is achieved; the pipeline stress concentration and damage phenomenon caused by pipeline sedimentation generated by pipe gallery sedimentation is prevented; completely-automatic all-weather running can be achieved, the rapid reaction to the sudden sedimentation accident can be achieved, in the aspect of sedimentation control, the precision is higher than that of manual operation, manual expenses can be saved, and the safety risk caused by the fact that a person frequently enters in and goes out of the comprehensive pipe gallery is reduced.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a support for automatic control of pipeline settlement for an urban comprehensive pipeline gallery. Background technique [0002] The urban comprehensive pipeline corridor is the comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. [0003] The interior of the urban comprehensive pipe gallery not only integrates the running water, gas, electricity, and communication pipelines that maintain urban functions, but also uses a variety of power, lighting, drainage an...

Problems solved by technology

[0004] At this stage, the settlement control of pipelines mostly adopts the method of manual monitoring. Through fixed installation of direct or indirect monitoring points on the pipeline, surveyors regularly use theodolite or total station to measure the elevation of each monitoring point and obtain settlement data. Engineering personnel According to the obtained data, in the vicinity of the uneven settlement point, the pipeline in this area shall be treated, and the pipeline foundation shall be manually excavated to reduce its height appropriately, or the pipeline shall be raised by hydraulic jacks and other equipment, and then the pipeline foundation shall be backfilled to raise the pipeline foundation appropriately. The height of the pipeline foundation, this method is time-consuming and labor-intensive, has a large disturbance to the pipeline, and has a low degree of automation. For long-distance pipelines, the manual correction error is large, so it is not suitable for popularization.
