Embodiment Construction

[0040] The present invention will be further described in conjunction with the accompanying drawings.

[0041] As shown in the figure, a quick removal device for shield belt conveyor muck in water-rich strata is mainly composed of a collection and drainage device at the bottom of the belt conveyor and a side drainage device of the belt conveyor, including a belt conveyor, an equipment bridge, and a heightened belt conveyor Splash guard Ⅰ for belt conveyor II, sump at the bottom, sump fixing device, sump drain valve, drain pipe, side drain sump, side drain sump fixing device, drain hole, side Water inlet pipe, side drain pipe, side drain sump drain valve, mud pump, main drain pipe.

[0042]The belt conveyor is installed on the equipment bridge, and the heightened splash guard I of the belt conveyor is installed on both sides of the bottom end of the belt conveyor (exit range of the screw conveyor) to prevent splashing of dregs at the outlet of the screw conveyor; Splash baffle...

Abstract

The invention discloses equipment and method for quickly clearing and transporting muck of a water-rich stratum shield belt conveyor, belongs to the technical field of shield construction, and can solve the problems that silt and water flow falling to the lower part of the belt conveyor are accumulated at a shield tail, a segment conveyor is submerged, normal tunneling cannot be performed and the like during earth pressure balance shield construction of a water-rich stratum. The equipment comprises the belt conveyor, a water collecting tank and a side drainage water collecting tank, wherein the water collecting tank and the side drainage water collecting tank are located at the bottom of the belt conveyor; a drainage hole is formed in the bottom of one end of the water collecting tank and connected with a drainage pipe I provided with a drainage valve I; a drainage hole is formed in the bottom of the side drainage water collecting tank and connected with a drainage pipe II provided with a drainage valve II; and the other end of the drainage pipe I is connected with a main drainage pipe through a slurry pump after being connected with the drainage pipe II. According to the invention, the muck and muddy water sliding from the bottom end of the belt conveyor and splashed to the position below the belt conveyor from the two sides of the belt conveyor are rapidly cleared and transported, and normal propelling of a shield tunneling machine is not affected.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to equipment and a method for quickly cleaning and transporting dregs of shield tunneling belt conveyors in water-rich formations. Background technique [0002] In recent years, with the great development of domestic urban rail transit, the shield method has been widely used in rail construction because of its advantages of safety, high efficiency and wide adaptability. Due to its extensive stratum adaptability and strong rock-breaking ability, earth pressure balance shield has increasingly become the first choice for shield tunneling construction under various complex stratum conditions. However, in the construction of water-rich strata, due to the high water content in the stratum, problems such as fragmentation and looseness are easily caused by weathering of the rock strata during the tunneling process of the shield machine. When the screw conveyor is not w...
