Well wall irrigating device and raise boring well wall supporting construction method

Abstract

The invention provides a well wall pouring device and a raise boring well wall supporting construction method. The well wall pouring device is structurally characterized in that a material guide table is welded to the edge of the upper end of a rotating template; a baffle is welded to the edge of the top end of the guide table. A flattening mechanism is connected to the periphery of the top of the rotary template or the periphery of the material guide table; a rotating shaft is arranged in the well wall irrigator; the rotating shaft is connected with the rotating template, the material guiding table and the baffle through spokes, and a connecting part is arranged at the top end. The construction method comprises the steps of manufacturing the well wall pouring device, excavating the vertical shaft, manufacturing the vertical shaft wall base, installing the well wall pouring device through a drill rod, placing the drill rod into the bottom of the vertical shaft, pouring concrete, rotating and slowly lifting the well wall pouring device, completing well wall pouring, and standing the well wall for curing. Compared with the prior art, in the well wall supporting construction period, personnel do not enter a well, the construction procedure is simplified, equipment and material input is reduced, a safe and comfortable working environment is created, and the engineering cost is reduced.

Description

Technical field [0001] The present invention relates to the field of underground engineering surrounding rock support, particularly to a well wall pourer and anti-well drilling wall support construction method. Background [0002] Small diameter shafts are widely used in economic life. The traditional construction methods are forward excavation method and reverse construction method. Drilling and blasting method is used to break rock, masonry, stacking, anchor spraying, watering and other ways to support. Construction is difficult and the security threat is great. [0003] In order to solve the above problems, the reverse well drilling rig was developed. During the tunneling of the reverse well drilling rig, the staff does not need to enter the unsafe well hole, the working environment is good, and the operation is safe. Other construction methods such as hanging tanks, climbing tanks, operators are avoided from falling rocks, water and harmful gases. Reverse drilling rig constr...

AI Technical Summary

Problems solved by technology

[0004] Surrounding rock conditions of small-diameter shafts are ever-changing, and most of them need support. During the shaft support period, construction personnel still need to enter the well to carry out operations. The construction efficiency is low and safety management is difficult.
