Subway station foundation pit excavation soil and waste conveying method

Abstract

The invention discloses a subway station foundation pit excavation soil and waste conveying method. A set of wave-shaped flange belt conveyor is arranged and comprises a conveyor body and a belt storage mechanism. The conveyor body is sequentially provided with a machine head horizontal section, a machine head inclined section and a machine head vertical section from the machine head end to the machine tail end. The machine head horizontal section is arranged on a ground foundation outside a foundation pit. The machine body vertical section is arranged on the side wall of a continuous wall inthe vertical direction, and the end portion of the machine body vertical section is close to the bottom of the foundation pit. As the excavation depth of the foundation pit increases, the length of awave-shaped flange conveying belt of the section of the belt storage mechanism can be reduced. When the length of the machine body vertical section needs to be extended continuously, the length of themachine head horizontal section can be shortened, and the extension to the machine body vertical section can be realized. According to the construction method, the wave-shaped flange belt conveyor isused for conveying soil and waste, so that soil and waste continuous conveying can be realized. As the depth of the foundation pit increases, the length of the wave-shaped flange belt conveyor can beprolonged. The automation degree is high. The labor intensity of workers is low. The soil and waste conveying efficiency is high.

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
