Description

Technical Field

[0001] This application relates to the field of railway subgrade support, specifically a debris flow prevention facility, and particularly to a novel prefabricated debris flow diversion channel. Background Technology

[0002] Debris flows are extremely destructive natural disasters, especially in summer when sudden and heavy rainfall can easily cause casualties and economic losses, highlighting the importance of debris flow prevention. Cast-in-place diversion channels offer advantages such as good integrity, high rigidity, good earthquake and impact resistance, and strong adaptability to irregular surfaces. However, their drawbacks are significant: the curing period is long, the surface flatness requirements are stringent, and when the surface collapses, the monolithic structure is prone to fracture and damage due to stress concentration. Furthermore, damaged channels are difficult to maintain or require complete demolition and reconstruction, resulting in high costs. Summary of the Invention

[0003] The purpose of this invention is to provide a novel prefabricated debris flow diversion channel to solve the problems of structural damage, low construction efficiency, and difficult maintenance caused by surface collapse of cast-in-place diversion channels.

[0004] The novel prefabricated debris flow diversion channel includes a left hook plate 1, a right clamping plate 2, a rubber waterproof pad 3, and a chemical expansion bolt 4.

[0005] The left hook plate 1 includes an inclined plate 5 and a horizontal plate 6. The horizontal plate 6 of the left hook plate 1 has a right-angle hook head 7 at its end, which is a prefabricated whole. The surface of the right-angle hook head 7 has a pre-drilled bolt hole 9. The upper half of the vertical surface of the right-angle hook head 7 is offset to the left, that is, the upper part is concave and the lower part is convex.

[0006] The right clamping plate 2 includes an inclined plate 5 and a horizontal plate 6. A right-angle clamping head 8 is prefabricated at the end of the horizontal plate 6. The right-angle clamping head 8 has pre-drilled bolt holes 311 on its surface, positioned identically to bolt hole 19. The lower half of the vertical surface of the right-angle clamping head 8 is offset to the right, meaning the upper part is convex and the lower part is concave. The bolt holes 19 of the right-angle hook head 7 and 31 of the right-angle clamping head 8 are overlapped one-to-one, and the overlap is filled with a rubber waterproof gasket 3.

[0007] The rubber waterproof pad 3 is made of elastic material with a thickness of 5mm. It is located at the overlap of the right-angle hook head 7 and the right-angle clamp head 8. The horizontal section of the rubber waterproof pad 3 has a second bolt hole 10 pre-drilled, and the position of the second bolt hole 10 is the same as that of the first bolt hole 9 and the third bolt hole 11. After alignment, the chemical expansion bolt 4 is inserted into the bolt hole, and the left hook plate 1, the right clamp plate 2, and the rubber waterproof pad 3 are connected to form an assembly module. The groove width of the assembly module is 2000mm.

[0008] All inclined plates 5 are tilted outwards with a slope ratio of 1:2. The top surface of the inclined plate 5 is 50mm long, and the vertical distance from its top surface to the bottom surface of the module is 2700mm.

[0009] The top surface of the horizontal plate 6 of the left hook plate 1 is 80mm long and 40mm high. The concave surface of the right-angle hook head 7 is 20mm long and 30mm high, and the convex surface is 70mm long and 30mm high. The bottom surface of the right-angle hook head 7 is connected to the bottom surface of the horizontal plate 6 by a chamfer with a chamfer width of 20mm.

[0010] The top surface of the horizontal plate 6 of the right card plate 2 is 70mm long and 40mm high. The convex surface of the right-angle card head 8 is 1200mm long and 25mm high, and the concave surface is 70mm long and 35mm high. The bottom surface of the right-angle card head 8 is connected to the bottom surface of the horizontal plate 6 by a chamfer, with a chamfer width of 20mm.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] (1) The structure is a prefabricated structure, which can be quickly assembled when building the diversion channel. Compared with the current construction technology, it shortens the construction time and improves the process quality and construction efficiency.

[0013] (2) The modular design can adapt to local collapse and deformation of the channel surface, avoiding overall breakage due to stress concentration; when the guide channel is partially damaged, only a single module needs to be replaced, significantly reducing maintenance costs.

[0014] (3) The modular structure supports flexible expansion and conformity with the terrain. By adjusting the assembly angle, it can adapt to irregular channels and significantly expand the engineering application scenarios of the diversion channel.

[0015] This invention achieves a systematic upgrade in the construction, protection, and maintenance efficiency of diversion channels through modular design. All materials used are common, with controllable costs and a mature supply chain, making it particularly suitable for large-scale deployment along major transportation arteries in high-risk debris flow areas.
