Description

Technical Field

[0001] The utility model relates to the technical field of highway tunnel drainage systems, in particular to a highway tunnel intercepting ditch structure with a mud retaining structure. Background Art

[0002] A mud retaining structure is a structure used to prevent mud or solid particles in the water from depositing at the tunnel exit or in the intercepting ditch. In a highway tunnel, the mud retaining structure is made of concrete, steel bars or other durable materials. Its design purpose is to ensure the effectiveness of the tunnel drainage system while reducing the amount of mud, garbage and other debris entering the drainage system, thereby extending the service life of the system.

[0003] After searching, the Chinese patent announcement number is: CN220705762U. The utility model relates to a highway tunnel intercepting ditch structure with a mud retaining structure, including an intercepting ditch and a mud retaining bank. The mud retaining bank is arranged at the inner bottom of the intercepting ditch. The two ends of the mud retaining bank are seamless with the inner walls of the intercepting ditch on both sides. The mud retaining bank is provided with a drainage hole. The drainage hole penetrates the mud retaining bank along the length direction of the intercepting ditch. The distance between the drainage hole and the inner bottom surface of the intercepting ditch is greater than or equal to 5 cm. The mud retaining bank is set at the inner bottom of the intercepting ditch so that the water in the intercepting ditch flows through the drainage hole of the mud retaining bank or from the top of the mud retaining bank, and the distance between the drainage hole and the inner bottom surface of the intercepting ditch is greater than or equal to 5 cm, so that the mud retaining bank can intercept the mud and mud in the flowing water. The intercepted mud is accumulated at the bottom or both sides of the drainage hole, thereby ensuring that the fluid entering the highway drainage system through the mud retaining bank can be discharged smoothly, and excessive mud and mud will not flow into the road surface and the tunnel entrance, bringing safety hazards to subsequent highway operations. However, this structure can complete the drainage task to a certain extent, but it is insufficient in interception when the amount of mud is large, which can easily lead to mud accumulation and affect the drainage effect. Utility Model Content

[0016] As a further description of the above technical solution:

[0017] Two limit blocks are fixedly connected to the left end of the inner bottom wall of the mud retaining trough, and fixing grooves are provided on the right sides of the two limit blocks.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Specifically, a mud retaining trough 4 is installed on the ditch mounting module 3. When water flows through the mud retaining trough 4, the barrier strip 6 can intercept large objects to the outside of the fixed block 5 to prevent large objects from entering the mud retaining trough 4 and causing blockage. The fixed block 5 is installed in the middle of the inner bottom wall of the mud retaining trough 4 to support and fix the diverter plate 7. The diverter plate 7 can disperse the water flow flowing into the mud retaining trough 4 into the mud storage pool 8. The mud storage pool 9 is located on the inner bottom wall of the mud storage pool 8, and is used to collect and store the mud deposited in the mud retaining trough 4. At the same time, the return plate 10 prevents the mud from being dispersed by the water flow, and the clearer water flows into the subsequent ditch module 1 through the upper guide trough 11.

[0040] Reference Figure 3 and Figure 4 The mounting structure 2 includes a side clamping strip 201, side mounting grooves 202 are provided on the front and rear sides of the inner wall of the ditch mounting module 3, two bottom fixing blocks 203 are fixedly connected to the bottom wall of the mud retaining ditch 4, two bottom fixing grooves 204 are provided on the inner bottom wall of the ditch mounting module 3, a clamping groove 205 is provided on the right side of the mud retaining ditch 4, a top plate 206 is meshedly connected to the inner wall of the clamping groove 205, and a positioning groove 207 is provided on the right side of the inner bottom wall of the ditch mounting module 3;

[0041] Specifically, the cooperation between the side clamping strip 201 and the side mounting groove 202 enables the mud retaining trough 4 to be stably installed in the ditch mounting module 3, and the engagement of the bottom fixing block 203 and the bottom fixing groove 204 further enhances the stability of the mud retaining trough 4. The engagement connection between the clamping groove 205 and the top plate 206 ensures that the water flow impact direction of the mud retaining trough 4 is also sufficiently fixed and supported, thereby ensuring the stability of the mud retaining trough 4 during operation. At the same time, the engagement design makes installation and disassembly relatively simple and convenient.

[0042] Reference Figure 2 and Figure 4 , the inner walls of the two mud storage tanks 9 are fixedly connected with two handle bars 12, and the tops of the multiple handle bars 12 are fixedly connected with handles 13; the right end of the diverter plate 7 is fixedly connected with a support block 14, and the support block 14 is fixedly connected to the right side of the top wall of the fixed block 5; the left end of the inner bottom wall of the mud retaining tank 4 is fixedly connected with two limit blocks 15, and the right sides of the two limit blocks 15 are provided with fixed grooves 16;

[0043] Specifically, the handle bar 12 on the inner wall of the mud storage tank 9 and the handle 13 on the top are combined together, which provides convenience for carrying the mud storage tank 9. The operator can easily lift the mud storage tank 9 filled with mud and sand from the intercepting ditch through the handle 13 and the handle bar 12, and clean or replace it. The support block 14 on the right side of the diverter plate 7 is fixedly connected to the right side of the top wall of the fixing block 5. This design ensures the stability of the diverter plate 7 and enhances the impact resistance of the diverter plate 7 to the water flow. The fixing groove 16 on the right side of the limit block 15 is used to fix the left side of the mud storage tank 9 to avoid direct impact of the water flow on the mud storage tank 9 and prevent the mud storage tank 9 from displacement or misalignment during use.

[0044] Reference Figure 1 and Figure 3 The front and rear ends of the right side of the gutter module 1 and the front and rear ends of the right side of the gutter installation module 3 are fixedly connected with meshing teeth 17, and the front and rear ends of the left side of the gutter module 1 and the front and rear ends of the left side of the gutter installation module 3 are provided with meshing grooves 18; the inner wall of the top plate 206 is fixedly connected with a positioning pin 19, and the inner bottom wall of the positioning groove 207 is provided with a positioning hole 20, and the outer wall of the positioning pin 19 is meshed with the inner wall of the positioning hole 20; the inner walls of the gutter module 1 and the gutter installation module 3 are both rounded;

[0045] Specifically, the arrangement of the meshing teeth 17 and the meshing grooves 18 enables the ditch module and the ditch mounting module 3 to be tightly connected and not easy to loosen. This connection method not only ensures the overall stability of the intercepting ditch, but also facilitates installation and disassembly, and facilitates subsequent maintenance and inspection work. The positioning pins 19 and the positioning holes 20 can ensure the precise positioning of the top plate 206 during the installation process, which helps to improve the accuracy and efficiency of the installation. The rounded inner walls of the ditch module 1 and the ditch mounting module 3 help reduce the resistance of the water flow in the ditch, and are not easy to accumulate mud and debris, thereby keeping the intercepting ditch unobstructed.

[0046] Working principle: the ditch module 1 and the ditch installation module 3 are the basic structures of the intercepting ditch. The ditch installation module 3 can be installed in the ditch module 1 with equal or unequal spacing, and the mud trough 4 can be installed on the ditch installation module 3. When the water flows through the mud trough 4, the mass of the mud is heavier than the water flow. When the water flows, the mud will be in the middle and lower layers of the water flow. The blocking bar 6 can intercept large objects outside the fixed block 5 to prevent large objects from entering the mud trough 4 and causing blockage. The fixed block 5 is installed in the middle of the inner bottom wall of the mud trough 4 to support and fix the diverter plate 7. The diverter plate 7 can disperse the water flowing into the mud trough 4 into the mud storage tank 8. The mud storage tank 9 is located on the inner bottom wall of the mud storage tank 8, and is used to collect and store the mud deposited in the mud trough 4. At the same time, the return plate 10 can prevent the mud from being blocked by the water flow. The relatively clear water flows into the subsequent ditch module 1 through the upper diversion groove 11, thereby effectively intercepting and collecting the silt in the tunnel water, ensuring the smooth and stable operation of the tunnel drainage system, and when installing the mud retaining trough 4, the mud retaining trough 4 can be installed vertically downward as a whole, and the cooperation between the side clamping strip 201 and the side mounting groove 202 enables the mud retaining trough 4 to be stably installed in the ditch mounting module 3, and the engagement of the bottom fixing block 203 and the bottom fixing groove 204 further enhances the stability of the mud retaining trough 4, and the engagement connection between the clamping groove 205 and the top plate 206 ensures that the water flow impact direction of the mud retaining trough 4 is also sufficiently fixed and supported, ensuring the stability of the mud retaining trough 4 during operation, and at the same time, the engagement design makes installation and disassembly relatively simple and convenient, thereby improving the efficiency of construction and maintenance.
