Problems solved by technology
The existing technology is to chisel the wall and use a breaker or manual hand-held jack for construction. This construction method takes a long time and requires a large amount of labor, which affects the construction period and has potential safety hazards. The demolished structure falls underground Also needs to be transported to the ground, additional shipping costs are required
After searching, there is no better construction scheme in the prior art

Embodiment Construction
[0026] Such as Figure 1~3 Among them, a method for dismantling the wall between the main structure and the auxiliary structure of the subway station includes the following steps:
[0027] S1, cutting the enclosure structure crown beam 1 with a diamond wire saw 8, forming a hanging hole 15 at the top;
[0028] The preferred solution is as figure 2 In, first punch vertical holes 13 at the two ends of the enclosure structure crown beam 1 to be cut, the bottom of the vertical holes 13 reaches the bottom of the enclosure structure crown beam 1, and punch horizontal holes 14 at the excavated side. The horizontal hole 14 refers to a horizontal hole, preferably, the horizontal hole 14 is inclined downward by 5° to 10°. Further preferably, the diameter of the horizontal hole 14 is larger than the diameter of the vertical hole 13 . After the horizontal hole 14 is connected with the vertical hole 13, the diamond wire saw 8 is inserted into the vertical hole 13 and the horizontal hol...

The invention provides a dismantling method suitable for a wall body between a main body structure and an accessory structure of a subway station, which comprises the following steps: S1, cutting a top beam of an enclosure structure by using a diamond fretsaw, and forming a lifting hole in the top; s2, a hanging support is arranged at the position of the hanging hole, and the anti-falling device is fixedly connected with the wall body; s3, the wall is cut into multiple sections in the vertical direction through the diamond fretsaw; s4, the diamond wire saw cuts the wall into a plurality of single concrete blocks in the horizontal direction; s5, the crane lifts out the single concrete block from the lifting hole; and S6, the steps S3-S5 are repeated from top to bottom, the wall body is cut into single concrete blocks to be hoisted out, and dismantling of the wall body between the main body structure and the accessory structure of the subway station is completed. The scheme of top fixing, block cutting and top lifting out is adopted, the construction efficiency is greatly improved, safety is high, and labor consumption is low. And a single piece of concrete is directly lifted out from the top, so that the workload of field cleaning is greatly reduced.
Description
technical field [0001] The invention relates to the field of interior construction of a subway station, in particular to a method for removing a wall between a main structure and an auxiliary structure of a subway station. Background technique [0002] After the main structure of the station is completed, the auxiliary structure construction is carried out. After the auxiliary structure construction is completed, the wall of the station enclosure structure needs to be removed, so that the main structure of the station and the auxiliary main structure are connected together. The existing technology is to chisel the wall and use a breaker or manual hand-held jack for construction. This construction method takes a long time and requires a large amount of labor, which affects the construction period and has potential safety hazards. The demolished structure falls underground It also needs to be transported to the ground, which requires additional transportation costs. After ret...
