Well-sinking vertical tunnelling machine

Abstract

The invention relates to large-scale machine equipment special for automatic mechanical tunnelling construction and adopted for well-sinking engineering, in particular to a well-sinking vertical tunnelling machine. A disc-type milling cutter is adopted for foot excavation based on an earthwork excavation construction work method, even excavation layer by layer is achieved in the modes of face excavation through a rolling-type milling cutter and simultaneous excavation and rotation, and muck is boxed and hoisted onto the ground to be loaded in time through special muck collection equipment; inorder to achieve engineering continuity, prefabricated building block masonry construction is adopted on the well wall, a hydraulic nitrogen impact hammer controlled by a level gauge conducts deviation correction during excavation at any time, the working principle of the hydraulic nitrogen impact hammer is that when encountering soil layers with uneven hardness, a mercury switch arranged in the machine starts the nitrogen hydraulic impact hammer to conduct high-frequency vibration when passing through the hard soil layer, and thus blade feet are cut into the hard soil layer; and meanwhile, the depth of the disc-type milling cutter is increased, through methods of simultaneous excavation and masonry, and simultaneous excavation and deviation correction, the construction efficiency is greatly improved, the construction cost is greatly lowered, and thus the construction quality is obviously guaranteed.

Description

Technical field: [0001] The invention relates to the field of basic construction, a special machine for caisson earthwork construction, specifically designed for caisson excavation operations, which can automatically dig earthwork at the bottom of caissons, automatically load and transport muck, and automatically open caissons. Correction correction intelligent automatic excavator. Background technique: [0002] Caisson is a basic construction technology widely used in the construction industry. It is used in bridges, anchorages, shield tunnels, mining shafts and other projects. Traditional caissons are mostly excavated manually and semi-mechanized. Or use high-pressure water to impact the soil layer and then use a mud pump to pump out the mud. The former has a long construction period and high labor intensity and is very unsafe, while the latter has low efficiency and serious pollution.

[0002] Caisson is a basic construction technology widely used in the construction industry. It is used in bridges, anchorages, shield tunnels, mining shafts and other projects. Traditional caissons are mostly excavated manually and semi-mechanized. Or use high-pressure water to impact the soil layer and then use a mud pump to pump out the mud. The former has a long construction period and high labor intensity and is very unsafe, while the latter has low efficiency and serious pollution. Both types of construction are prone to uneven settlement of caissons and cause deflection.
