A method for conveying dregs and soil for excavation of subway station foundation pit

Abstract

The invention discloses a method for conveying slag and soil for excavating a foundation pit of a subway station. A set of corrugated sidewall belt conveyors is arranged. The corrugated sidewall belt conveyor includes a conveyor body and a belt storage mechanism; the conveyor body consists of a machine head. From the end to the end of the machine, there are the horizontal section of the nose, the inclined section of the body and the vertical section of the machine body; the horizontal section of the machine head is arranged on the ground foundation outside the foundation pit, and the vertical section of the machine body is arranged on the side wall of the continuous wall along the vertical direction. And its end is close to the bottom of the foundation pit; as the excavation depth of the foundation pit increases, the length of the corrugated sidewall conveyor belt of the belt storage mechanism section can be reduced; when it is necessary to continue to extend the length of the vertical section of the body, it can be shortened. The length of the horizontal section of the head, extending to the vertical section of the body. The construction method uses the corrugated sidewall conveyor to transport the muck, which can realize the continuous transportation of the muck, and can extend the length of the corrugated sidewall conveyor with the increase of the depth of the foundation pit. The degree of automation is high, the labor intensity of workers is low, and the muck High delivery efficiency.

Description

technical field [0001] The invention belongs to the technical field of urban subway construction, and in particular relates to a method for conveying excavated dregs from foundation pits of subway stations. Background technique [0002] Subway construction usually begins with the excavation of the foundation pit of the station, and then works towards the two ends. The general station foundation pit is rectangular, with a length of up to 200m and a depth of tens of meters. The earthwork construction of the foundation pit of the subway station is generally carried out along the vertical slope of the station, and excavated successively according to the procedures of layering, segmenting and block. The shallow earthwork of the foundation pit is usually excavated by ordinary excavators. When the foundation pit reaches a certain depth, an ordinary excavator is arranged at the bottom of the foundation pit, and a long-arm excavator is arranged at the edge of the foundation pit. Th...

Problems solved by technology

[0003] There are obvious disadvantages in the above-mentioned foundation pit muck transportation method: the number of excavators that need to be configured is large, and long-arm excavators need to be used, the construction cost is high, and equipment preparation is difficult; Slow, there is an obvious contradiction between the two, and as the foundation pit deepens, the contradiction becomes more obvious

Commonly used cranes and grabs also have low construction efficiency and cannot meet the construction requirements of rapid slag discharge
