Problems solved by technology
[0004] 1. Destroy the structural integrity and durability of the shield segment; the implantation of expansion bolts will inevitably damage the shield segment to the concrete interior and its steel structure, accelerate the corrosion of the internal steel structure, and cause internal stress distribution Uneven, affecting its bearing capacity and life
[0005] 2. Affect the balance of force between the shields; remove the segment fixing nuts for the fixing method of the equipment installation platform, and destroy the original force balance between the shields
[0006] 3. The installation of expansion screws requires a power supply, which requires a higher on-site power supply
[0007] 4. The expansion screw cannot be disassembled, which brings inconvenience to the maintenance and adjustment of the equipment in the later stage

The invention relates to the technical field of shield tunnel engineering, in particular to a fixing device for tunnel shield segment surfaces. The fixing device comprises a fastening piece in a shield segment fixing hole, a hook-shaped connecting rod and a segment surface fastening mounting piece, wherein the fastening piece in the shield segment fixing hole comprises a top hole fixator, a nut sleeve and a connecting rod; the connecting rod adopts a threaded structure and is matched with threads of the top hole fixator and the nut sleeve; the hook-shaped connecting rod adopts a structure withone side being hook shaped and the other side being threaded rod shaped, and is used for connecting between the fastening piece in the shield segment fixing hole and the segment surface fastening mounting piece; and the segment surface fastening mounting piece comprises a surface mounting plate and a supporting leg with an inclined plane. According to the fixing device, equipment fixing is realized through an inherent structure in the shield segment fixing hole, additional drilling is not required, damage to a segment structure is prevented, smoke and noise are not produced during mounting construction, mounting positions are flexible, and the fixing device is convenient to dismount and mount.
Description
technical field [0001] The invention relates to the technical field of tunneling engineering, in particular to a fixing device for the surface of a tunnel shield segment. Background technique [0002] With the rapid development of urbanization and economy in recent years, the prefabricated shield tunnel structure has become an important part of tunnel rapid excavation and installation. The installation of traditional tunnel internal equipment is usually fastened with expansion screws or loosened shield segment fixing screws. [0003] The disadvantages of this type of fixed method are: [0004] 1. Destroy the structural integrity and durability of the shield segment; the implantation of expansion bolts will inevitably damage the shield segment to the concrete interior and its steel structure, accelerate the corrosion of the internal steel structure, and cause internal stress distribution Unevenness affects its bearing capacity and life. [0005] 2. Affect the balance of fo...
