Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a clamp that can prevent longitudinal blind pipes from floating. Background Technology

[0002] Longitudinal drainage blind pipes in tunnels are permeable blind pipes installed along the longitudinal direction of the tunnel on the outer side of the bottom of the secondary lining. They are primarily used to collect and drain groundwater or seepage water behind the tunnel lining. The longitudinal drainage blind pipes collect water flowing from the tunnel arch and arch walls, and introduce it into the tunnel side ditch or central drainage ditch through transverse drainage pipes, ultimately draining it out of the tunnel. By promptly draining accumulated water behind the lining, they prevent water pressure from damaging the lining structure, avoid tunnel leakage, and protect the lining structure.

[0003] However, several problems arise during the on-site installation of longitudinal drainage blind pipes. Firstly, the limited space at the base makes installation difficult, often resulting in haphazard laying or the use of crushed stones, leading to poor fixation and difficulty in maintaining the slope consistent with the tunnel's longitudinal slope. Localized bulges or depressions significantly restrict the tunnel's drainage effect. In cases of obstructed passage, water accumulation and increasing water pressure can cause cracks and leaks in the tunnel structure. Secondly, the pouring of the secondary lining concrete can easily cause the longitudinal drainage blind pipes to float, shift, or even break, or be knocked off or flattened, thus greatly affecting their effectiveness.

[0039] Example 2

[0040] Reference Appendix Figures 2-4 The other structures are the same as in Embodiment 1, except that the issue of fixing the reinforcing bars is considered in this embodiment.

[0041] The reinforcing bar 1 is connected to a crossbar 19, and the crossbar 19 is threadedly connected to a fixing sleeve 4. The fixing sleeve 4 is slidably connected to a top block 5 that can slide out of the fixing sleeve 4. The fixing sleeve 4 is slidably connected to a sliding sleeve 3. The contact surface between the sliding sleeve 3 and the top block 5 is an inclined surface.

[0045] Further, a magnet is arranged, the ratchet block 7 is made of iron material, and the magnetic force of the magnet is greater than the elastic force of the compression spring 8, so when it is necessary to disassemble, the magnet is placed outside the fixed sleeve 4, the magnetic force of the magnet can drive the ratchet block 7 to move away from the ratchet groove 9, so as to release the limiting of the sliding sleeve 3, and at this time, the sliding sleeve 3 is moved outward, so as to realize the disassembly of the top block 5.

[0047] Embodiment three

[0048] Reference to the accompanying drawings Figure 5 The other structures are the same as those in embodiment one, and the difference lies in that in the embodiment, the fixing of the snap ring to the longitudinal drainage blind pipe is considered;
