Quick treatment method and casing of shield screw conveyor stuck

Abstract

The present invention provides a fast processing method for jamming of a shield screw conveyor, comprising: S10: determining the jamming area; S20: determining the size of the incision in the jamming area, cutting the protective cylinder to form an incision for maintenance, and cleaning the screw through the incision There is a foreign body stuck in the conveyor; S30: the cleaning is completed; S40: the incision is closed again with the incision plate. The fast processing method for jamming of shield screw conveyor provided by the present invention, on the basis of the original inspection, cuts an opening of a certain size at an appropriate position on the side of the protective cylinder of the screw conveyor, cleans the internal gravel and boulders, and finally re-aligns the incision Weld and seal. The invention avoids workers to clean up directly inside, greatly reduces the operation risk of construction personnel, has high processing efficiency, and well solves the problem of delay in construction period caused by jamming machine, and the blocking method is simple and easy to implement. The efficient and safe solution of emergencies has certain guiding significance for the existing shield construction and is worthy of promotion.

Description

Technical field [0001] The present invention relates to the field of underground tunnel shield construction techniques, and more particularly to a fast processing method of a shield helical conveyor card machine and a cartridge. Background technique [0002] As the "pioneer" of urban subway construction, the shield machine is high, the degree of mechanization is high, the excavation speed is fast, and the formation is small, which has become the primary work method of underground tunnel construction in my country. The composition of the shield machine is complex, the screw conveyor is a component of the shield, and the slag inside the soil is discharged, so that the shield can be continuously advanced in the formation, on the one hand, control the bottom pressure of the conveyor, and maintain shield excavation. Pressure pressure balance to ensure that the shield is normal, and its effect is huge. At the same time, my country's region is vast, and the shield is caused by the compl...

Problems solved by technology

[0004] In the existing technology, it is time-consuming and labor-intensive to clean the debris by manually entering the soil bin or the exit of the screw machine, and it is difficult to ensure the safety of the construction personnel. Or adding a sleeve to separate the gravel, clay, etc. It also takes a long time. Once the shutdown time is long, it will not only affect the construction period, but also cause the shield machine to sink when the geological conditions are relatively bad, which will affect the original line design of the shield section, and the cost will be even greater.
