Abstract
Description
Technical Field
[0001] The utility model relates to a novel anti-slip drainage pipe with a barb structure, belonging to the technical field of drainage pipes. Background Art
[0002] Tunnel lining leakage is the most common hazard in tunnel engineering. The causes of leakage are diverse and the treatment is extremely difficult. If not properly treated, it may cause accidents such as traffic safety and structural safety. The potential hazards should not be underestimated. Especially in karst development areas or water-rich sections with broken surrounding rocks, a large amount of groundwater often accumulates behind the tunnel lining and often leaks into the tunnel in the form of pressurized streams, seriously affecting the normal operation of the tunnel. In response to the above-mentioned concentrated stream-like pressurized water outflow, the conventional treatment solutions of drilling grooves inside the lining to bury pipes for drainage or installing diversion troughs on the lining surface for drainage have certain structural safety hazards. The long-term impact of large water pressure is very likely to cause the drainage pipes covered only by a thin layer of concrete to be squeezed into the tunnel, or cause the diversion troughs anchored to the lining surface to loosen and fall off.
[0003] Therefore, in view of the above situation, it is of great practical significance to study a new anti-slip drainage pipe with a barbed structure. Utility Model Content
[0004] In view of this, the purpose of the present invention is to provide a new anti-slip drainage pipe with a barb structure, so as to at least solve the problems mentioned in the background technology.
[0005] The purpose of this utility model is achieved through the following technical solutions:
[0006] The utility model relates to a novel anti-slip drainage pipe with a barb structure, comprising a pipe body, and a plurality of deformable barb structures are arranged on the outer surface of the pipe body.
[0007] Furthermore, the barb structure is a triangular, rectangular or needle-shaped spring piece, which can be fixed to the outer surface of the tube body by welding.
[0008] Furthermore, the barb structure is arranged obliquely along the insertion direction of the tube body, and the inclination angle of the barb structure is 30-60 degrees.
[0009] Furthermore, there is a flow-blocking structure inside the pipe body for slowing down the flow rate of water.
[0010] Furthermore, the flow-blocking structure is a spiral chute, a dot-shaped protrusion or a ring-shaped thread structure arranged on the inner wall of the tube body.
[0011] Furthermore, an elbow structure is provided at the water outlet end of the pipe body.
[0012] Furthermore, the pipe body and the elbow structure are arranged at an angle of 60-90 degrees.
[0013] Furthermore, the tube body and the elbow structure are an integrally formed structure; or, the tube body and the elbow structure are connected by screwing or welding.
[0014] Furthermore, an anchor plate is provided at the water outlet end of the pipe body, and a plurality of mounting holes are evenly distributed in the circumferential direction on the anchor plate.
[0015] Furthermore, the anchor plate is clamped or screwed onto the outer circumference of the water outlet end of the pipe body; the anchor plate is an elastic structure.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] The utility model has a simple structure, low cost, and convenient and efficient construction. It improves the existing drainage pipe used for tunnel construction by adding a deformable barb structure on the outer circumference of the drainage pipe. When the drainage pipe is inserted into the radial drainage hole of the tunnel, the barb structure can move closer to the drainage pipe wall to ensure that the drainage pipe can be smoothly inserted; thereafter, when the water pressure in the drainage hole is too high and squeezes the drainage pipe, the barb structure can effectively prevent the drainage pipe from moving outward, ensuring that the drainage construction is carried out smoothly and efficiently. In addition, adding a flow-blocking structure to slow down the flow rate of water in the drainage pipe can effectively deal with the situation of large-flow groundwater leakage in the tunnel, effectively avoiding the potential structural safety hazards caused by high-pressure water impact, and greatly improving the safety and durability of the tunnel groundwater diversion and drainage structure.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] like Figure 1-Figure 3 As shown, the first embodiment of the present invention provides a new anti-slip drain pipe with a barb structure, including a pipe body 1, and a plurality of deformable barb structures 2 are provided on the outer surface of the pipe body 1. By arranging the deformable barb structure 2 outside the drain pipe, when the drain pipe is inserted into the drain hole 6, it can be moved closer to the drain pipe wall to ensure that the drain pipe can be smoothly inserted; when the water pressure squeezes the drain pipe toward the outer end of the drain hole 6, the barb structure 2 can effectively prevent the drain pipe from moving outward.
[0026] The barb structure 2 is a triangular, rectangular, or needle-shaped spring element, and can be welded to the outer surface of the pipe body 1. The barb structure 2 is tilted along the insertion direction of the pipe body 1, with an angle of 30-60 degrees. This allows the pipe body 1 to elastically deform and move toward the drain pipe wall when inserted into the drain hole 6. When water accumulates in the drain hole 6 and squeezes the drain pipe, the barb structure 2, under the action of its elastic restoring force, generates significant friction with the inner wall of the drain hole 6, thereby preventing the drain pipe from moving outward.
[0027] The pipe body 1 also includes a flow-reducing structure 3 for slowing down the water flow. This structure can be a spiral chute, dot-shaped protrusions, or circular threads arranged on the inner wall of the pipe body 1. This structure increases the friction between the pipe interior and the water flow, thereby slowing down the water flow and effectively avoiding potential structural safety hazards caused by high-pressure water shock.
[0028] The outlet end of the pipe body 1 is equipped with an elbow structure 4, which redirects the water flow downward, facilitating drainage and further reducing water flow. Specifically, the pipe body 1 and the elbow structure 4 are arranged at a 60-90 degree angle. The pipe body 1 and the elbow structure 4 are integrally formed, resulting in low manufacturing costs. Alternatively, the pipe body 1 and the elbow structure 4 can be screwed or welded together for easy assembly and replacement.
[0029] The pipe body 1 and the elbow structure 4 are both made of stainless steel plates, which have the advantages of corrosion resistance and impact resistance, and can greatly improve the safety and durability of the tunnel groundwater drainage structure.
[0030] An anchor plate 5 is also provided at the outlet end of pipe body 1. Several mounting holes are evenly distributed around the plate, serving as a secondary measure to prevent outward slippage of pipe body 1. Anchor plate 5 can be snapped or screwed onto the outer circumference of the outlet end of pipe body 1. Anchor plate 5 utilizes an elastic structure, such as a rubber pad or steel pad, to allow a certain degree of deformation of the drain pipe along the drain hole, maximizing the load-bearing properties of the elastic toothed structure.
[0031] The working principle and process of the device:
[0032] When water accumulates behind the tunnel lining, pipe body 1 is inserted into the drain hole 6 located at the arch foot of the side wall of the flooded section. The barb structure 2 then moves closer to the outer wall of pipe body 1, ensuring smooth insertion. When water pressure pushes against the outer end of drain hole 6, the barb structure 2 effectively prevents the drain pipe from moving outward. Once pipe body 1 is inserted into the drain hole, anchor plate 5 is aligned with the end face of the drain hole. Anchor bolts are installed in the mounting holes of anchor plate 5, securing pipe body 1 to the tunnel lining and further preventing it from slipping outward.
[0033] The above description is only a preferred embodiment of the present invention and does not constitute any form of confidentiality restriction on the present invention. Any simple modification, equivalent change and modification of the above embodiment made based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
