Underground pipe gallery pipe section assembly equipment and construction method

Abstract

The invention relates to underground pipe gallery pipe section assembly equipment and a construction method. The equipment includes a pipe-laying machine, an assembling robot arm, an alignment trolleyand a pipe truck, wherein the pipe-laying machine includes a main beam, an auxiliary leg, a front leg, a rear leg and a lifting crane, the assembling robot arm is located at a lower portion of the front leg and is provided with a hydraulic lifting mechanism and a front end lateral alignment mechanism to realize longitudinal and lateral alignment of a front end of a pipe gallery, the alignment trolley is located in an assembled pipe section and is provided with a lateral hydraulic overhang alignment mechanism to realize lateral alignment of a rear end of the pipe gallery, the pipe truck is provided with a turning mechanism to turn the pipe gallery, and the construction method includes pipe section transportation, pipe section turning, pipe section lifting and pipe section installation. Theequipment is advantaged in that transportation and laying equipment functions are integrated together for construction, not only can transportation and turning of the pipe section be realized, but also lifting and installation of the pipe section can be realized, moreover, construction efficiency is further improved, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of pipe gallery assembly, in particular to an underground pipe gallery pipe section assembly equipment and a construction method thereof. Background technique [0002] The urban underground comprehensive pipe gallery is an effective way to solve the problems of repeated excavation of the ground "road zipper" and the spider web overhead lines of the main street in the process of urban construction. However, at present, the vast majority of the construction of urban underground comprehensive pipe gallery adopts the construction methods of grading and excavation, bracket support, and cast-in-place pipe gallery. This method has a large on-site workload, and it is difficult to guarantee the quality of on-site pouring. The impact is great; a few integrated pipe corridors are prefabricated in the factory and transported to the site for assembly. At present, all prefabricated assembly schemes use truck cranes or cr...

AI Technical Summary

Problems solved by technology

Due to the large slope next to the foundation pit of the pipe gallery and the bearing problem on the slope, the crane station is far away, and only small-tonnage pipe gallery pipe joints can be lifted and assembled

In this way, there are many assembly seams between the pipe sections of the pipe gallery, high precision requirements for butt joint assembly, troublesome butt joint assembly, and at the same time increase the probability of water seepage and leakage at the joints
