Description

Technical Field

[0001] This utility model relates to the field of drainage engineering facilities technology, and in particular to a prefabricated road drainage ditch. Background Technology

[0002] Currently, in mountainous wind farms in southern my country, most road drainage ditches still employ on-site construction techniques, primarily including two methods: on-site formwork and pouring of ordinary concrete, and brick-built drainage ditches. On-site formwork and pouring construction is complex, and the quality of the drainage ditches is difficult to guarantee due to variations in construction skill. Brick-built drainage ditches are less efficient and less effective than cast-in-place concrete. In short, both of these traditional design schemes require extensive on-site wet work, are cumbersome, have long construction cycles, and require a large amount of manual labor to complete, resulting in high labor and time costs.

[0052] Furthermore, in a specific embodiment of this utility model, the first connecting member 42, the second connecting member 43, and the third connecting member 47 can all be made of short channel steel, while the first support rod 45 and the second support rod 46 can be made of long channel steel, which can effectively reduce the weight while having good mechanical properties; the second connecting member 43 has a hole for the second threaded rod 41 to pass through, and the diameter of the hole only needs to be slightly larger than the outer diameter of the second threaded rod 41, preferably in contact with the surface of the second threaded rod 41, so that the sliding of the second connecting member 43 on the second threaded rod 41 has a certain damping effect; the first support rod 45 and the second support rod 46 are all hinged to the first connecting member 42, the second connecting member 43, and the third connecting member 47 by bolts.

[0053] According to an embodiment of the present invention, a prefabricated road drainage ditch is provided, wherein a support arm 48 is provided on the side of the third connector 47 near the side plate 2, and a support block 49 is provided at the end of the support arm 48 away from the third connector 47; the side plate 2 is provided with a support groove 24 for cooperating with the support block 49; specifically, the support block 49 can be a metal block, and its shape can be rectangular, circular or other suitable shape, and correspondingly, the shape of the support groove 24 is matched with the shape of the support block 49.

[0054] According to an embodiment of the present invention, a prefabricated road drainage ditch is provided, wherein the first direction is the direction of water flow in the drainage ditch, and the second direction is the vertical direction.

[0055] According to an embodiment of the present invention, a prefabricated road drainage ditch is provided, wherein a second assembly groove 13 is formed between the first assembly grooves 11 on both sides of the base plate 1; a second assembly key 6 is provided in the second assembly groove 13, and the joints of adjacent second assembly keys 6 are staggered with the joints of adjacent base plates 1. The second assembly keys 6 can connect adjacent base plates 1, and the second assembly keys 6 overlap on the joints of adjacent base plates 1. The staggered joint design can prevent water from directly seeping into the ground through the joints of the base plates 1.

[0056] According to an embodiment of this utility model, a prefabricated road drainage ditch is provided with cement mortar layers on the contact surfaces of the side plate 2 and the bottom plate 1, the joints of adjacent bottom plates 1, and the joints of adjacent side plates 2. These layers are used to bond the joints between the components, thereby increasing waterproof performance while also enhancing overall integrity and structural stability.

[0057] Furthermore, in a feasible embodiment of this utility model, the prefabricated road drainage ditch provided by this utility model, in actual use:

[0058] First, the base plate 1, as the main component of the prefabricated road drainage ditch, is located at the bottom of the drainage ditch and can connect two parallel side plates 2. By engaging the first serrated structure 12 on the drainage ditch base plate 1 with the second serrated structure 22 on the drainage ditch side wall plate, the friction is increased, and the integrity of the drainage ditch base plate 1 and the side wall plate is enhanced. By engaging the first assembly groove 11 with the first assembly key 21 on the side wall plate, the lateral displacement of the side plate 2 relative to the base plate 1 is prevented.

[0059] Secondly, by evenly distributing the anchor holes 5 on the base plate 1, penetrating the bottom plate 1 of the drainage ditch, and having a second placement groove 14 at the penetration position, the pre-tightening component 3 can pass through the anchor hole 5 and fix the fixing seat 32 in the second placement groove 14 to prevent the fixing seat 32 from sliding; the second assembly groove 13 is arranged along the water flow direction of the drainage ditch and can fit with the second assembly key 6 of the adjacent base plate 1, thereby connecting them into a whole.

[0060] Furthermore, the side plates 2 are connected together using the support assembly 4 to enhance the overall integrity of the drainage ditch and resist the lateral soil pressure on the outside of the drainage ditch, thus preventing large deformation of the drainage ditch cross section. The position of the second connecting piece 43 on the second screw can be adjusted by turning the position of the adjusting nut 44. By controlling the tilt angle of the second support rod 46, the extension distance of the horizontal support arm 48 connected to it can be adjusted, thereby controlling the ability of the drainage ditch side plate 2 to resist the lateral soil pressure. The top of the first threaded rod 31 of the pre-tightening assembly 3 is fitted with the pad 33, and the bottom of the first threaded rod 31 is welded to the fixing seat 32, passing through the anchor hole 5 on the entire side plate 2 and the bottom plate 1. The magnitude of the pre-tightening force between the side plate 2 and the bottom plate 1 is controlled by adjusting the pre-tightening nut 34 at the top of the first threaded rod 31.

[0061] Finally, apply a layer of cement mortar to the joints between the components.
