System and construction method for head turn and translation of shield trolley

Abstract

The invention discloses a system and construction method for head turn and translation of a shield trolley. According to the system and construction method for the head turn and translation of the shield trolley, the trolley is pulled to turn a head by using a pulley block device and a limiting device and utilizing an electromobile matched with shield, finally, a jack is used to fine tune, the head turn of the trolley is obtained, construction efficiency is greatly improved, at the same time, safety of construction is increased, and a head turn path is more accurate; and according to the system, structures of all related devices are simple, mechanical equipment used in construction is conventional associated equipment of shield construction, implementation is high, and the devices can be circulated.

Description

technical field [0001] The patent of the present invention relates to the field of subway construction, in particular to a U-turn, translational system and construction method of a shield trolley. Background technique [0002] When there is no lifting operation condition in a confined space, it is necessary to move the received shield machine, supporting trolley and unearthed battery car to another line for a second start in the station structure. Traditional U-turn or translation construction usually Now lay the steel plate on the ground, and then make a simple platform, fix the supporting trolley or unearthed battery car on the platform, use the jack to push the platform to move on the steel plate, when the jack completes the jacking of one cylinder stroke, add a jacking Iron, in this cycle for jacking, the construction efficiency of this type is low, and many jacking iron components are required, and the jacking position can only be dynamically adjusted according to the p...

[0002] When there is no hoisting operation condition in a confined space, it is necessary to move the received shield machine, supporting trolley and unearthed battery car to another line for a second start in the station structure. Traditional U-turn or translation construction usually Now lay the steel plate on the ground, and then make a simple platform, fix the supporting trolley or unearthed battery car on the platform, and use the jack to push the platform to move on the steel plate. Iron, in this cycle for jacking, the construction efficiency of this type is low, and many jacking iron components are required, and the position of the jack can only be dynamically adjusted according to the position of the platform during the on-site jacking process, and then the elongation can be calculated, which has the advantages of Large uncertainty, and at the same time, the turning path cannot be precisely controlled. During construction, the phenomenon of jacking displacement exceeding the limit or scraping the side wall often occurs, which affects construction safety and progress
