A shield machine center rotary assembly machine and tail shield rapid installation and disassembly hoisting method

Abstract

The invention discloses a method for quickly mounting and dismounting hoisting of a center revolving-type assembling machine and a tail shield of a shield tunneling machine. The method comprises the following steps that 1, quickly mounting hoisting of the center revolving-type assembling machine and the tail shield of the shield tunneling machine is conducted, specifically, the tail shield and theassembling machine are overlapped with each other to form a whole, the whole of the assembling machine and the tail shield is slowly hoisted into a well, and connecting bolts of the assembling machine and a middle shield H beam are mounted, and whole hoisting of the tail shield and the assembling machine is finished; and 2, quickly dismounting hoisting of the center revolving-type assembling machine and the tail shield is conducted, specifically, all the connecting bolts between the middle shield H beam and the assembling machine are disconnected, so that the assembling machine and the tail shield are wholly and slowly lifted and hoisted from the interior of a well, after the assembling machine and the tail shield are hoisted to the ground, a hand-pulling hoist between the tail shield andthe assembling machine is disconnected, the assembling machine and the tail shield are separated, and dismounting hoisting operation is finished. According to the method for quickly mounting and dismounting hoisting of the center revolving-type assembling machine and the tail shield of the shield tunneling machine, the number of hoisting times is reduced, and the construction working efficiency of mounting and dismounting hoisting is improved.

Description

Technical field [0001] The invention relates to the field of shield tunnel construction in the fields of urban rail transit, water conservancy, electric power and the like, in particular to a central rotary assembly machine of a shield machine and a fast installation, disassembly and hoisting method for a tail shield. Background technique [0002] Shield tunnel construction technology has been widely used in the domestic subway market, municipal water transmission tunnels, power tunnels and other fields. Shield machines are frequently installed in the upper and lower shafts. The present invention is suitable for solving similar constructions. The installation, disassembly and lifting of the assembling machine and the tail shield simplify the construction process and improve the construction efficiency. [0003] The traditional center rotary assembly machine and tail shield of the traditional shield machine adopt a step-by-step hoisting method. Downhole hoisting and dismantling pro...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a fast installation and disassembly hoisting method of the center rotary assembling machine and the tail shield of the shield machine, which can solve the problems of large space requirements, overall hoisting, and many hoisting times. After the tail shield is put on, the overall longitudinal length is less than the longitudinal length required to install the assembly machine first and then put on the tail shield. The assembly machine and the tail shield are hoisted up and down the shaft as a whole, reducing the number of hoisting and improving the construction efficiency of installation, disassembly, and hoisting.
