Description

Technical Field

[0001] The utility model relates to the field of shield tunnel construction, in particular to a shield tunnel composite gravel layer mud slag processing device. Background Art

[0002] Shield tunneling is a fully mechanized construction method in the concealed excavation method. It pushes the shield machine into the ground, and supports the surrounding rock with the shield shell and segments to prevent collapse into the tunnel. At the same time, a cutting device is used to excavate the soil in front of the excavation face, and the soil is transported out of the hole by the excavation machinery. The jack is used to pressurize and push it forward at the rear, and precast concrete segments are assembled. The composite gravel layer mud residue generated during tunnel excavation needs to be processed in time to avoid burying the initially formed tunnel. At present, there are two main ways of transporting and processing composite gravel layer mud residue: mechanical and manual. Due to the large size of the conveying machinery, it is suitable for transporting large amounts of composite gravel layer mud residue. When the amount of composite gravel layer mud residue is small, it is shoveled manually and put into the conveyor vehicle for transportation. However, manual shoveling is time-consuming and labor-intensive, consumes a lot of physical strength, and is inefficient, which is not conducive to efficient construction.

[0003] In order to solve the above problems, we propose a shield tunnel composite gravel layer mud slag processing equipment to improve the shortcomings of the existing technology. Utility Model Content
