Abstract

The invention relates to a hand hole plugging device for segment bolts and a construction method thereof, comprising: a first protective cover sleeved on one end of the segment bolts and a second protective cover sleeved on the other end of the segment bolts a cover; a positioning rod arranged on the inner side of the segment and corresponding to the segment bolt; a fixing structure fixed on one end of the positioning rod, the fixing structure is detachably fixed on the first protective cover to limit the first protective cover; The movable structure is connected to the movable structure of the positioning rod in a movable position, and the movable structure is detachably fixed on the second protective cover by adjusting the position of the movable structure, and the movable structure and the positioning rod are fixed to fix the first protective cover. protective cover and second protective cover. By limiting the first protective cover and the second protective cover, the pressing is firm to prevent the problem that the hand hole is blocked and the gap cannot be closely adhered.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a hand hole plugging device for segment bolts and a construction method thereof. Background technique [0002] In the design requirements of shield tunneling tunnels, bolts are used to connect two adjacent segments to each other, and it is required that the formed tunnel segment bolts be hand-hole blocked, and the treatment requirement is 180° (including 180°) of the tunnel. The above is a plastic protective cover, embedded with foamed two-component polyurethane material. [0003] The traditional construction method is that the two-component polyurethane A and B liquids are poured into the plastic protective cup at a ratio of 1:1 for stirring (about 4g). After stirring, the foaming and expansion start. And firmly press the protective cover on the bolt with your hand to wait for the foam to be bonded to the segment bolt. This process takes about 2 minutes. This method requir...
