Referring to fig. 1, the basement anti-floating anchor comprises a vertically arranged steel reinforcement cage 1, a positioning bracket 2 and a telescopic component 3; the locating support 2 sets up on framework 1, and the locating support 2 is followed the length direction interval setting of framework 1, flexible subassembly 3 sets up on locating support 2, and when staff's stock slip casting, thick liquid spare promotes flexible subassembly 3 and pierces the hole lateral wall of anchor eye 4 to improve the interact between anti-floating anchor pole and the soil layer, improved the resistance to plucking of anti-floating stock promptly.
The anchor holes 4 can be drilled and formed by a spiral hole-turning dry operation method, a pressurized water drilling hole-forming method, a submerged drilling hole-forming method and the like.
The steel reinforcement framework 1 is formed by binding and welding a plurality of longitudinal steel bars; used for bearing the pulling force of the anti-floating anchor rod. The upper end of the reinforcement cage 1 is provided with a bent part 11, and the bent part 11 is fixedly connected with an upper basement structure, so that the structural loss of the basement structure caused by floating is reduced.
The top and the bottom of the anti-floating anchor rod are provided with positioning brackets 2, and the middle parts of the anti-floating anchor rod are uniformly arranged along the axial direction of the steel reinforcement framework 1. The positioning bracket 2 is a cylindrical frame formed by bending steel bars, and a certain avoiding gap is formed between the positioning bracket 2 and the wall of the anchor hole 4. When a worker uses hoisting equipment to hoist the anti-floating anchor rod into the anchor hole 4 which is arranged in advance, the outer edge of the positioning bracket 2 is intermittently collided and abutted with the side wall of the anchor hole 4; thereby ensuring that the reinforcement cage 1 is vertically arranged without obvious inclination.
Referring to fig. 2 and 3, the telescopic assembly 3 is disposed obliquely upward; specifically, the distance from the telescopic component 3 to the steel reinforcement framework 1 increases gradually from bottom to top. So that the telescopic components 3 are penetrated into the soil layers at the two sides of the anchor holes 4 obliquely upwards, and the acting force of the soil layers on the anti-floating anchor rods is further improved.
Specifically, the telescopic assembly 3 includes a guide cylinder 31, a plug connector 32 penetrating through the guide cylinder 31, a pushing member 33 disposed at one end of the plug connector 32 near the reinforcement cage 1, and a limiting member 34 disposed at one end of the plug connector 32 far away from the reinforcement cage 1. In the present embodiment, the guide cylinder 31 is a circular hollow cylinder, and the plug connector 32 is rod-shaped; in other embodiments, the plug 32 may also be a block structure, a plate structure, or the like.
The guide cylinder 31 is fixed below the positioning bracket 2. In this embodiment, the guide cylinder 31 is welded to the positioning bracket 2, so as to improve the connection strength between the telescopic assembly 3 and the anti-floating anchor. In other embodiments, the guide cylinder 31 may be obliquely fixed to the positioning bracket 2 by binding or the like.
When the reinforcement cage 1 of the anti-floating anchor rod is hung into the anchor hole 4, the plug connector 32 is enabled to be abutted with the sleeve by the abutting block on the plug connector 32 under the action of gravity, so that the plug connector 32 is reduced from sliding out of the guide cylinder 31.

The rubber sheet has certain rigidity and elasticity, so that the baffle 7 is arranged at the end part of the plug connector 32 in a penetrating way, and the baffle 7 clamps the plug connector 32 under the action of self elastic force; thereby reducing the risk of the barrier 7 falling off.
When the slurry injected into the anchor hole 4 pushes the plug 32 to be inserted into the hole side wall through the pushing piece 33, the baffle 7 can be abutted against the hole side wall of the anchor hole 4, so that the dropping of soil blocks on the hole side wall is reduced. The plug connector 32 is slidably connected with the baffle, and the plug connector 32 is continuously inserted into the soil layer of the side wall of the hole under the action of slurry.
It is noted that in this embodiment, there are two grouting pipes of the anti-floating anchor, one for normal pressure grouting and the other for secondary high pressure grouting.

When the strength of the cement for the first time reaches a certain strength; and (3) performing secondary high-pressure grouting by a worker, connecting a grouting pipe with the secondary high-pressure grouting pipe by the worker, and performing secondary grouting from the bottom of the hole. The plug 32 is further forced to penetrate into the soil layer due to the pressure of the secondary grouting and the pressure of the primary grouting, i.e. the chassis of the telescopic assembly 3 is abutted against the guide cylinder 31.
Referring to fig. 4, after the anti-floating anchor is completely solidified, a worker sequentially lays a waterproof structure 8 and a basement bottom plate 9 on the upper portion of the anchor. The waterproof structure 8 sequentially comprises a plain concrete cushion layer 81, a waterproof layer 82 paved by waterproof coiled materials and waterproof materials and a plain concrete protection layer 83 arranged on the upper part of the waterproof layer 82 from bottom to top; thereby improving the waterproof performance of the basement.
