Problems solved by technology
The bolt body is left in the underground foundation pit of the construction site, which is easy to cause difficulties in the construction of the underground foundation pit at the reconstruction site, and is also not conducive to the recycling of resources
[0003] Bolt support technology, no matter it is used for temporary support or permanent support, as the bolt left in the rock mass soil layer after construction, it will generally be permanently buried underground and in the soil layer, causing pollution of the underground space, and at the same time After the anchor rod is constructed, the anchor section and a part of the free section will be exposed outside the red line of the building, which will cause troubles in foundation construction when other construction projects are developed around the building.

Embodiment Construction
[0017] The structural combination and implementation steps of the present invention will be further described below in conjunction with the accompanying drawings.
[0018] Such as figure 1 The schematic diagram of the structure of the embodiment of the recoverable anchor device of the present invention includes: anchoring end (1), anchoring sleeve (2), anchoring rod body (3), heating wire (4), screw rod (5), inner ring (6) , Threaded Insert (7), Cushion Plug (8), Tray (9), Hex Nut (10), and Adhesive (11). Among them, the anchoring end (1) contacts and interacts with the soil in a large area to generate an end-bearing anchoring force; the anchoring rod body (3) is hollow inside, and two inner rings of the same size are arranged inside the anchor rod; the rod body (3 ) and the anchoring end (1) are connected by a screw (5), the screw (5) is fixed at the threaded insert (7), and the screw (5) is fixed by the inner ring (6) and penetrated inside the rod body. In this embodiment,...

The invention discloses a recyclable end support anchor rod device and a construction process. The device mainly comprises an anchoring end (1), an anchoring sleeve (2) and an anchoring rod (3), wherein the anchoring end (1) takes the shape of a square or rectangle for anchoring and preventing sliding; the anchoring end (1) is connected with the anchoring rod (3) through a threaded insert (7); a screw rod (5) is fixed by using an inner ring (6) and penetrates through the rod body; the length of the screw rod (5) is equal to the anchoring sleeve (2); and an extended part of the screw rod (5) isspirally fixed at the threaded insert (7). An electric heating wire (4) which can be electrified to generate heat is arranged inside the anchoring rod (3); and a gap between the electric heating wire(4) and the anchoring rod (3) is filled with an insulating filler (12). The anchoring sleeve (2) is adhered to the anchoring rod (3) by using an adhesive (11), and the adhesive (11) is molten in an indirect heating mode, so that rods can be recycled conveniently later; and the recyclable end support anchor rod device is low in cost, good in anchoring capability and easy to recycle and reuse.
Description
technical field [0001] The invention relates to the field of road engineering in civil engineering, in particular to a recyclable end bearing bolt device and a construction process. Background technique [0002] Anchor rods are not only used for main reinforcement of mines, slopes, tunnels, and dams, but also for foundation pit construction. The bolt body is left in the underground foundation pit of the construction site, which is likely to cause difficulties in the construction of the underground foundation pit at the reconstruction site, and is also not conducive to the recycling of resources. [0003] Bolt support technology, no matter it is used for temporary support or permanent support, as the bolt left in the rock mass soil layer after construction, it will generally be permanently buried underground and in the soil layer, causing pollution of the underground space, and at the same time After the anchor rod is constructed, its anchored section and a part of the free ...
