Temporary trolley tool for shield split launching

Abstract

The invention discloses a temporary trolley tool for shield split launching, and relates to the technical field of shield split. The device comprises a first fixing plate, the first fixing plate is in a square shape, the cross section of the first fixing plate is in an I shape, a conveying hopper is arranged on the inner side of the first fixing plate, supporting columns are fixed to the four end corners of the bottom of the first fixing plate, a second fixing plate is fixed to the bottoms of the supporting columns, and the second fixing plate is in a U shape; and the cross section of the second fixing plate is also I-shaped. Through a series of improvements, the whole shield tunneling machine can be hoisted into a well, the number of hoisting times of large pieces is reduced, the work efficiency is improved, the temporary trolley tool can be simple in structure, easy to operate and convenient to mount and dismount, various pipelines needed by split starting do not need to be purchased in the use process, cost is saved, more labor force is saved, the construction cost is reduced, and the construction efficiency is improved. And the safety coefficient of duct piece transportation and muck transportation is high.

Description

technical field [0001] The invention belongs to the field of shield tunneling split technology, and in particular relates to a temporary trolley tooling for starting a shield tunnel split. Background technique [0002] With the gradual popularization of the application of shield machines in various municipal tunnel projects, it often occurs that the length of the starting section is insufficient, or the position of the lifting hole is not suitable, resulting in the shield machine not being able to start the whole machine according to the normal situation. The general treatment method for this situation is to initiate the split shield; [0003] The split originates from the main body of the shield tunneling machine in the station, and the subsequent matching does not go into the hole together with the shield tunneling machine, but is connected by pipelines. The excavation of the shield tunnel is carried out at the excavation port of the screw conveyor by a small soil bucket. ...

AI Technical Summary

Problems solved by technology

[0004] When the existing shield splits are used, the shield machine needs to be hoisted in stages, and the crawler crane and other equipment have a long service life and high cost; it is also necessary to purchase nearly 100 meters of shield machine pipelines, which is costly. In addition, the pipeline is easy to knot and break, posing potential safety hazards; unearthed and hoisted segments are difficult to operate and the construction efficiency is low
