Watered sandy stratum earth pressure balance shield residue earth flattening equipment for tunnel construction

Abstract

The invention discloses watered sandy stratum earth pressure balance shield residue earth flattening equipment for tunnel construction, relates to the technical field of residue earth flattening equipment, in particular to the watered sandy stratum earth pressure balance shield residue earth flattening equipment for tunnel construction. The watered sandy stratum earth pressure balance shield residue earth flattening equipment for tunnel construction comprises a middle pressure wheel, an underframe plate and nozzles; the left side of the middle pressure wheel is provided with an auxiliary fixedplate; the left side of the auxiliary fixed plate is provided with a back pressure wheel; the front end of the underframe plate is provided with an auxiliary gas tank; the underframe plate is arranged at the front end of the auxiliary fixed plate; one end, far away from the underframe plate, of the auxiliary gas tank is provided with an auxiliary drive motor; and the left side of the auxiliary drive motor is provided with an auxiliary connection rod. According to the watered sandy stratum earth pressure balance shield residue earth flattening equipment for tunnel construction, a dust mask canprevent external dust from entering into a guide rod, and oil immersed sponge can effectively provide a lubrication effect to a push rod so as to lighten mechanical abrasion between the guide rod andthe push rod and be capable of effectively lightening the impact force between the guide rod and the push rod.

Description

technical field [0001] The invention relates to the technical field of dregs flattening equipment, in particular to a dregs flattening equipment for water-rich sand layer soil pressure balance shields for tunnel construction. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels, and muck is only a kind of construction waste. According to the "Urban Construction Waste Management Regulations", construction waste refers to construction units, construction units newly built, Reconstruction, expansion and demolition of various buildings, structures, pipe networks, etc., as well as the spoils, spoils and other wastes generated in the process of decoration and decoration of houses by residents, and the waste is treated by the soil pressure balance shield technology of water-rich sand layers. use e...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a water-rich sand layer soil pressure balance shield dregs flattening equipment for tunnel construction, which solves the problem that the dregs cannot be rolled very well during tunnel construction in the above-mentioned background technology. Good steering can not prevent the dregs from being adsorbed on the outer surface of the pressure wheel, and it can't crush large particles or stones with good ones, so as to ensure the high efficiency of the flattening equipment on the tunnel road surface, it can't be very good Well, collecting and flattening the slag extruded by the pressure roller will not be able to alleviate the problem of dust flying during construction.
