Description

Technical Field

[0001] This utility model belongs to the field of drainage ditch technology, specifically relating to a spliced ​​UHPC drainage ditch. Background Technology

[0002] In the construction of infrastructure such as municipal engineering, underground parking garages, and highways, drainage ditches are key drainage and flood control components. Their structural stability, seepage prevention performance, and construction efficiency directly affect the quality and service life of the entire project. Traditional drainage ditches are mostly constructed by casting ordinary concrete on-site with formwork. This method has inherent defects such as complex construction procedures, long construction period, and difficulty in quality control. In addition, ordinary concrete has insufficient strength and weak corrosion resistance. Under the long-term effects of vehicle cyclic dynamic loads and groundwater erosion, the ditch is prone to cracking and damage, resulting in high maintenance costs in the later stages. To address the aforementioned issues, prefabricated construction technology has been gradually applied to the field of drainage ditches. Among these technologies, ultra-high performance concrete (UHPC) has become the preferred material for prefabricated drainage ditch components due to its excellent mechanical properties, durability, and corrosion resistance. Various splicing UHPC drainage ditch structures have emerged in the existing technology. By setting connecting protrusions and grooves, tenons and mortises at the ends of the prefabricated ditch body, rapid splicing is achieved, which effectively simplifies the construction process and shortens the construction cycle. At the same time, by leveraging the performance advantages of UHPC material itself, the overall load-bearing capacity and service life of the drainage ditch are improved. However, existing interlocking UHPC drainage ditches still have key technical pain points in practical applications, making it difficult to simultaneously meet high standards of leak prevention and structural strength requirements. On the one hand, in terms of splicing sealing performance, the splicing joints are prone to sealing failure, leading to sewage leakage and pollution of the surrounding soil and groundwater environment; on the other hand, they are difficult to adapt to the long-term use needs of different working conditions. On the other hand, in terms of the strength of the splicing structure, the existing splicing methods mostly rely on the simple interlocking of protrusions and grooves or simple fasteners. The force transmission performance of the splicing surface is poor. Under the action of vehicle load, soil lateral pressure or foundation settlement, stress concentration is easily generated at the splicing point, which leads to loosening, deformation or even damage of the connection structure, thereby affecting the overall structural stability of the drainage ditch and limiting its application range in heavy-load and complex geological environments. Therefore, developing a new type of spliced ​​UHPC drainage ditch structure to address the shortcomings of existing spliced ​​UHPC drainage ditch technology has become a technical problem that urgently needs to be solved by those skilled in the art.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figures 1-5 As shown, a modular UHPC drainage ditch includes a first splicing plate 1 and a second splicing plate 2, which are arranged opposite each other. The top of the first splicing plate 1 and the second splicing plate 2 is fitted with a cover plate 3. Multiple drainage grooves 6 are evenly arranged inside the cover plate 3. Protrusions 4 are fixed on both sides of the bottom of the cover plate 3. The top of the first splicing plate 1 and the second splicing plate 2 are provided with grooves 5, and two protrusions 4 are inserted into two grooves 5. Multiple connecting structures 13 are fixed at both ends of the first splicing plate 1 and the second splicing plate 2. A first sealing plate 8 is fixed to the bottom of the first splicing plate 1 and the side near the second splicing plate 2. A second sealing plate 9 is fixed to the bottom of the second splicing plate 2 and the side near the first splicing plate 1. The first sealing plate 8 is set on top of the second sealing plate 9. The first splicing plate 1 and the second splicing plate 2 are spliced ​​together, and leakage is prevented by the first sealing plate 8 and the second sealing plate 9. The sewage is blocked by the first sealing plate 8 and the second sealing plate 9. The sewage is blocked by the first sealing plate 8 and the second sealing plate 9, thus preventing sewage leakage. The cover plate 3 can cover the top of the drainage ditch and receive rainwater and sewage through the trough 6. The protrusion 4 is inserted into the groove 5, so that the cover plate 3 can be stably installed on the top of the first splicing plate 1 and the second splicing plate 2. The connection structure 13 includes a through hole and a plug rod. When the first splicing plate 1 is spliced ​​with another first splicing plate 1, the plug rod on one of the first splicing plates 1 is inserted into the through hole on the other first splicing plate 1. The second splicing plate 2 can be spliced ​​with another second splicing plate 2 in the above manner. A leak-proof structure is installed between the first sealing plate 8 and the second sealing plate 9.

[0016] See attached document Figure 4 The leak-proof structure includes a first mounting groove 10, which is located between the second splicing plate 2 and the second sealing plate 9. The end of the first sealing plate 8 is inserted into the first mounting groove 10. When the sewage is between the first splicing plate 1 and the second splicing plate 2, it can be blocked in the first step by the first sealing plate 8 inserted into the first mounting groove 10. The leak-proof structure also includes at least one sealing block 11 fixed to the top of the second sealing plate 9. The bottom of the first sealing plate 8 is provided with a sealing groove 12, and the number of sealing grooves 12 and the sealing blocks 11 are the same and their positions correspond. The sealing blocks 11 are inserted into the sealing grooves 12, thereby preventing rainwater from reaching the second sealing plate 9 even after passing through the first mounting groove 10. When the first sealing plate 8 and the second sealing plate 9 are connected, the sealing block 11 can be inserted into the sealing groove 12 to further block sewage, thereby preventing sewage leakage and ensuring the practicality of the drainage ditch. Flexible pads are provided on the outer side of the first sealing plate 8 near the first mounting groove 10 and on the inner wall of the sealing groove 12. The flexible pads are made of rubber or silicone, so that when the first sealing plate 8 is inserted into the first mounting groove 10, the sealing pads can deform to ensure the sealing between the first sealing plate 8 and the first mounting groove 10. When the sealing block 11 is inserted into the sealing groove 12, the sealing pads can deform to ensure the sealing between the sealing block 11 and the sealing groove 12.

[0017] See attached document Figure 3A sealing ring 7 is provided at the bottom of the cover plate 3 and on the outside of the protrusion 4. With the sealing ring 7, when the protrusion 4 is inserted into the groove 5, the sealing ring 7 can wrap around the protrusion 4, thereby blocking the protrusion 4 and the groove 5, thus ensuring the stability of the protrusion 4 inside the groove 5, and thus ensuring the stability of the cover plate 3.

[0018] To ensure the structural strength between the first splicing panel 1 and the second splicing panel 2, refer to the attached... Figure 3 An installation strip 14 is fixed to the inner wall of the first splicing plate 1 near its top. A slide bar 15 is fitted inside the installation strip 14, and a spring 18 is installed within the installation strip 14. The spring 18 and the slide bar 15 abut against each other. A connecting frame 17 is provided on the inner wall of the second splicing plate 2 at a position corresponding to the slide bar 15. The slide bar 15 is inserted into the connecting frame 17. The spring force of the spring 18 causes the slide bar 15 to spring towards the connecting frame 17, thus inserting it into the connecting frame 17. Therefore, the arrangement of the slide bar 15, the installation strip 14, and the connecting frame 17 ensures that the first splicing plate 1 and the second splicing plate 2 do not tilt towards each other or away from each other. The first and second sealing plates 8 and 9 are arranged at an angle to ensure that the first splicing plate 1 and the second splicing plate 2 will not move away from or towards each other, thereby ensuring the overall stability and structural strength of the first splicing plate 1 and the second splicing plate 2. A threaded rod 16 is fixed to one end of the slide bar 15 near the connecting frame 17, and a threaded groove is provided in the connecting frame 17. The threaded rod 16 is threaded into the threaded groove. By turning the threaded rod 16, the threaded rod 16 drives the slide bar 15 to rotate and slide in the mounting strip 14, thereby making the threaded rod 16 threaded into the threaded groove inside the connecting frame 17, thus ensuring the tightness of the connection between the mounting strip 14, the slide bar 15 and the connecting frame 17.

[0019] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
