Abstract

The invention discloses special excavating equipment applicable to underground excavation construction of underground engineering. The special excavating equipment comprises a supporting mechanism, an excavating mechanism, a prefabricated part assembling mechanism and a transporting mechanism which is used for transporting a soil body and a prefabricated part. The special excavating equipment has the beneficial effects that (1) the complexity degree and equipment cost of the excavating equipment are greatly reduced as compared with those of the traditional shield machine; (2) the excavating equipment has a special-shaped excavating cross section, can be applicable to different construction environments and excavating cross sections, can effectively excavate a shallow soil coverage area (generally 2 to 3 m in depth) of an urban trunk road, and meanwhile, can precisely determine an excavating angle according to a rupture angle of a rock soil body; (3) the excavating equipment is developed relying on an innovative underground engineering construction method, and can realize the functions of top plate supporting, cross section excavating, prefabricated part assembling, muck and prefabricated part transporting, synchronous grouting and the like in a construction process.

Description

technical field [0001] The invention relates to an underground engineering excavation equipment, and mainly relates to a special excavation equipment suitable for underground engineering underground excavation construction. Background technique [0002] Excavation equipment is relatively important equipment in the process of underground engineering construction. Traditional foundation pit excavation usually uses equipment such as excavators, loaders, dump trucks and other equipment to cooperate with manual construction. The operation process of these mechanical equipment is cumbersome and the construction efficiency is low. . Most of the mechanized construction of tunnels use shield machines, which have high construction efficiency, relatively mature technology and high construction reliability; The adaptability puts forward higher requirements; however, the construction method of the shield machine can only manufacture the corresponding shield machine according to the sect...
