Guiding and transporting system for pipeline erection on foundation pit and construction method of system

Abstract

The invention discloses a guiding and transporting system for pipeline erection on a foundation pit and a construction method of the system. The guiding and transporting system comprises guiding and transporting sliding tools symmetrically arranged on two sides of the edge of the foundation pit in the pipeline erection direction, two embedded pulleys in the extension direction of two ends of a connecting line between the guiding and transporting sliding tools, and a closed rope connected with the two guiding and transporting sliding tools and the two embedded pulleys in a winding mode. Each guiding and transporting tool comprises a supporting frame and a supporting pulley set arranged at the top of the supporting frame, and auxiliary positioning devices are arranged on two outer sides, perpendicular to the pipeline arrangement direction, of the embedded pulleys. During construction, through the arrangement of the guiding and transporting tools, rapid guiding and transporting of the pipeline is achieved, the arrangement of the supporting pulleys plays a role in supporting point or sliding of the rope during circular transportation, on one hand, the required height during pipeline guiding and transporting is guaranteed by the supporting frame, and on the other hand, supporting force required for pipeline guiding and transporting is provided by the supporting frame. Due to the effect of the embedded pulleys, the winding connection of the rope is ensured, and the power for rope circulation can be provided when the pipeline is guided and transported. The auxiliary positioning device can lock the rope and is used for fixing the rope when the rope does not circulate.

Description

technical field [0001] The invention belongs to the field of pipe gallery pipeline engineering, and in particular relates to a pipeline erection guide system on a foundation pit and a construction method thereof. Background technique [0002] The underground comprehensive pipe gallery is to build a tunnel space underground, which integrates various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., and has special inspection ports, hoisting ports and monitoring systems, and implements unified planning, Unified design, unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. During the construction of underground pipe gallery [0003] It is necessary to dig a foundation pit for the laying of the pipeline. Therefore, the pipeline needs to be guided, surveyed and erected in the foundation pit. However, it takes a lot of manpower to guide the pipeline during pipeline co...
