Abstract

The invention discloses a composite-stratum shield tunneling machine waste-soil transporting system, and solves the problems that when shield tunneling is conducted in a composite stratum, an assembly operating area in a shield tunneling machine is prone to accumulating water, and the operating environment is prone to being polluted by waste soil. The composite-stratum shield tunneling machine waste soil transporting system comprises a shield-tunneling-machine soil bin (1), a screw conveyor (2) is connected on the shield-tunneling-machine soil bin (1), the head end of a belt-conveyor bridge-frame slope section (4) is arranged below a soil discharging port (3) of the screw conveyor, and a water-blocking arc-shaped plate (6) is arranged at the head end of the belt-conveyor bridge-frame slope section (4); and a residue-blocking rubber-sheet closed cylinder (14) is connected on the soil discharging port (3) of the screw conveyor, a buffering rubber roller set (7) is arranged below head-end belt of a conveying belt (8) on the belt-conveyor bridge-frame slope section, mud blocking plates (12) are arranged on the two sides of a conveying belt on a belt-conveyor platform-car flat-slope section (9), and a high-pressure water-spraying system (10) used for conducting spraying on tail-potion belt is arranged at a car-frame tail-portion soil discharging port (11). According to the composite-stratum shield tunneling machine waste-soil transporting system, cleaning of the assembly operating area and safe conducting of assembly operation are ensured.

Description

technical field [0001] The invention relates to a slag transportation system in a shield machine, in particular to a slag transportation system in a shield machine when the shield is used to form a compound stratum. Background technique [0002] In subway shield construction, composite strata are often encountered. Composite strata are strata distributed with different ages, different lithologies or different weathering degrees, and showing different geotechnical properties. The physical properties of the rock and soil in this formation and the permeability coefficient of the soil are quite different. During shield excavation, the geology is complex and changeable. The cutter head sometimes cuts hard rock, and sometimes cuts soft soil with different water content. After the cut muck enters the soil bin, it is transported to the belt through the screw machine outlet on the shield machine. On the conveyor, the belt conveyor is composed of a bridge slope section and a trolley ...
