Description
Technical field
The invention belongs to underground mine concrete building structures technical field, particularly relate to shaft wall cast-in-situ concrete joint, connect stubble construction erecting device.
Background technology
Vertical is the most important engineering in underground mining mine, be responsible for lifting, transport, ventilate, draining and personal security are passed through.Shaft of vertical well uses circular cross section mostly, and according to different technology arrangement requirements, mineshaft diameter differs in size, and shaft wall thickness is not less than armored concrete and the concrete supporting structure of 300mm.In recent years, application along with metal large form, shaft of vertical well step pouring molding, every section of height is not less than 3000mm, while shaft construction Completed advance rate is increasingly faster, also the stubble that connects bringing shaft wall upper-lower section cast-in-place concrete connects insecure, the uncompacted disadvantage of internal structure, and the quality connecing batch junction surface directly affects the globality of the borehole wall, mechanical property and water proofing property.In order to improve mechanical strength and the water proofing property at upper-lower section concrete junction surface.Existing frequently-used connecting plate is constructed, or uses window construction to connect stubble.When using connecting plate construction, along the all-round reserved cutter feet angle of pit shaft bottom the epimere borehole wall, a height of 200mm of angle, when the pouring of hypomere borehole wall final section template is to during away from angle lower end 100mm, plug jointing form, limit insert edge fills concrete, it is achieved connect stubble.When using window to connect batch, bottom the epimere borehole wall along girth at a certain distance, no more than 2000mm, reserved 300mm × 300mm connects a batch window, and concrete pours into from this window, finally connects a batch window with the closure of piece wood piece template, it is achieved connect stubble.Existing defects is that apparatus structure is complicated, difficulty of construction is big；Time-consuming, engineering time length, seriously restrict Completed advance rate；The concrete of same label is still used owing to upper-lower section concrete connects joint portion, again without connecting elements, template in construction process base opening easily deforms and supports without external force extruding, concrete connects stubble and still suffers from connecting insecure, the uncompacted disadvantage of internal structure, total quality cannot ensure, particularly in the deep formation that hydraulic pressure is bigger, cast-in-situ concrete joint connects joint portion mechanical strength and sealing waterproof problem fails to solve very well.
