Transportation method of large pipelines in the construction of comprehensive pipeline gallery

Abstract

The invention relates to a transportation method of a large-scale pipeline in the construction of an integrated pipe gallery, Before transportation, a transport vehicle is made, wherein, the front andrear ends of the frame are provided with external hanging points, the top two sides are provided with limited position blocks, the bottom two sides are provided with wheels, one wheel is a small wheel and is supported on the bottom surface of the cabin, and the other wheel is a large wheel and is supported on the bottom surface of the drain ditch, so as to ensure that the top of the frame is flush; During transportation, a windlass is arranged at the front and rear of the transport vehicle and the wire ropes of the front and rear windlass are respectively connected with the external hanging points at the front and rear ends of the frame, Lift the large-scale pipeline between the stoppers on both sides of the frame top, and use the winch to draw the transport vehicle forward and backward.After the transport vehicle arrives at the designated place, lift the large-scale pipeline onto the pipeline pier. The method makes up the difference between the height of the drainage ditch and the height of the drainage ditch, does not cause large sloshing, and has high working efficiency and low cost.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for transporting large pipelines in the construction of a comprehensive pipeline gallery. Background technique [0002] In urban construction, there are many pipelines entering the comprehensive pipe gallery, and its cross-section is divided into multiple cabins, among which large pipelines such as urban water supply and drainage are arranged separately in the cabins. In the construction of the comprehensive pipe gallery, there are two problems in the transportation of large pipelines: 1) the cabin space is too small to enter large mechanical equipment; The space of the cabin itself is small, so the ground where the drainage ditch is located must be used to ensure the normal transportation of large pipelines. The current construction method is to fill the drainage ditch to keep the ground level, but this method is time-consuming, labor-intensive and mater...

In the construction of the comprehensive pipe gallery, there are two problems in the transportation of large pipelines: 1) the cabin space is too small to enter large mechanical equipment; The space of the cabin itself is small, so the ground where the drainage ditch is located must be used to ensure the normal transportation of large pipelines. The current construction method is to fill the drainage ditch to keep the ground level, but this method is time-consuming, labor-intensive and material-consuming, and the construction is complicated
