Scum cleaning and conveying system for arc-shaped bottom surface of tunnel

Abstract

The invention discloses a scum cleaning and conveying system for an arc-shaped bottom surface of a tunnel, which comprises a middle cleaning machine and side cleaning machines hinged to the two sides of the middle cleaning machine, and a middle dust collection cavity in the middle cleaning machine and side dust collection cavities in the side cleaning machines are communicated with the lower end of a same scum conveying pipeline; the upper end of the slag conveying pipeline points to the interior of a garbage storage box arranged on the belt conveyor, and the belt conveyor is longitudinally arranged in the tunnel in a full-length mode. The cleaning machine has the advantages that the steel shell, the horizontal cleaning wheel disc with the elastic steel wire brush and the transverse roller shaft with the multiple rows of steel wire brushes are utilized by the cleaning machine to clean large-mass scum into a cavity; the scum cleaning system is used by hinging and combining a middle cleaning machine and a side cleaning machine to adapt to the arc-shaped bottom surface of the tunnel; and scum in the middle dust collection cavity and the side dust collection cavities is rapidly transferred into a garbage storage box on the belt conveyor to be conveyed out through the scum conveying pipeline, the whole pipeline is closed, and dust flying can be avoided.

Description

technical field [0001] The invention belongs to the technical field of tunnel cleaning, and in particular relates to a system for cleaning and transporting scum on the arc-shaped bottom of a tunnel. Background technique [0002] In the prior art, the earth pressure balance shield machine uses a belt to transport the muck, and the muck is transported to a battery car for transporting the muck. During the transportation of muck and the construction process, it is unavoidable for muck to fall and debris to scatter. In addition, the mortar transport vehicle flushes and cleans the grout of the grouting pipeline, resulting in slag falling within the range of the trolley. The cleaning method currently adopted is mainly manual cleaning, and the cleaned scum is stored in a slag bag. However, the manual cleaning method is not only time-consuming and laborious, but also the storage of the slag bags will affect the normal passage space of the battery car. [0003] In addition, the bot...
