Description

Technical Field

[0001] The present invention belongs to the technical field of drainage structures, and in particular relates to a bridge deck anti-blocking drainage structure for highway bridge engineering construction. Background Art

[0002] When water accumulates on the deck of a highway bridge during rainy days, the tires of high-speed vehicles traveling on it can slip and lose control, leading to serious traffic accidents such as vehicle skidding or rollovers. Therefore, drainage troughs are often installed on both sides of the bridge pavement to guide the accumulated water into drainage pipes and then drain back to the bridge. Drainage troughs are assembled using U-shaped steel welds to accommodate the length of the bridge deck. This assembly process is inefficient and cannot be quickly assembled, making repair of damaged troughs complex and difficult.

[0003] The existing public authorization announcement number is CN209538022U, which is a drainage trough for bridge deck drainage of highway bridges. It includes a steel body, a male tenon is fixed to the bottom of one end of the steel body, and the male tenon is provided with a mounting groove along the longitudinal direction. One end of the compression spring is fixedly connected to the mounting groove, and the compression spring is loosely matched with the mounting groove. The other end of the compression spring is connected to a ball, and the ball partially extends out of the mounting groove, and the diameter of the ball is smaller than the opening size of the mounting groove. The beneficial effect is that the utility model realizes the rapid assembly between the two steel bodies by the cooperation of the male tenon and the female groove, and locks with the limiting plate by the ball being inserted into the limiting groove, replacing the method of welding the steel body to form the drainage trough. The assembly method is fast and convenient, which improves the assembly efficiency of the drainage trough. At the same time, when part of the drainage trough is damaged, it only needs to be removed and replaced with the corresponding steel body, which is easy to operate.

[0004] The above-mentioned disclosed technology makes it convenient and quick to splice the drainage trough, but during use, due to the sediment deposited on the bridge deck brought by the movement of vehicles, the single-structure drainage trough is prone to sediment accumulation during use, thereby causing the drainage trough to be blocked. The blocked drainage trough cannot play a drainage role and needs to be manually cleaned. It cannot adjust itself when blocked, resulting in poor use effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a bridge deck anti-blocking drainage structure for highway bridge engineering construction. The structure can automatically adjust when the drainage trough is blocked by sediment, thereby alleviating the situation of sediment blocking the drainage trough, so that the drainage trough can continue to be used and will not immediately lose its drainage function due to blockage.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the 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. Specific embodiment one:

[0037] See also Figure 1-10 As shown, the present invention is a bridge deck anti-blocking drainage structure for highway bridge engineering construction, including a fixed groove 1, a drainage valve 31 connected to the buoyancy chamber 5 is fixed on one side of the fixed groove 1, a drainage groove 2 with an open top is fixed inside the fixed groove 1, and a sedimentation groove 3 is fixed at the bottom of the drainage groove 2. The cross section of the sedimentation groove 3 is U-shaped, and the bottom of the sedimentation groove 3 is arc-shaped.

[0038] Partitions 4 are fixed on both side surfaces of the sedimentation trough 3, and the ends of the two partitions 4 away from the sedimentation trough 3 are fixedly connected to the inner wall of the fixed trough 1; the two partitions 4 and the sedimentation trough 3 and the drainage trough 2 divide the inner cavity of the fixed trough 1 into two buoyancy chambers 5 and a sediment collection chamber 6. The two buoyancy chambers 5 are located on both sides of the drainage trough 2 and are symmetrically arranged about the drainage trough 2.

[0039] A buoyancy seat 7 is provided at the bottom of each buoyancy chamber 5, and a push rod 8 is fixed on the top of the buoyancy seat 7. The top end of the push rod 8 passes through the top of the fixed groove 1 and a connecting plate 9 is fixed to the top. The end of the connecting plate 9 away from the push rod 8 extends to the bottom of the drainage groove 2. The bottom end of the connecting plate 9 is fixed to the head support frame 10, and a sealing strip 11 is fixed on the support frame 10.

[0040] A water inlet trough 32 connected to the buoyancy chamber 5 is opened at the top of the drainage trough 2, and a filter grille is fixed inside the water inlet trough 32. A sand lowering trough 12 cooperating with the sealing strip 11 is opened at the bottom of the drainage trough 2. The drainage trough 2 is connected to the sedimentation tank 3 through the sand lowering trough 12.

[0041] A sealing flange 25 is fixed on the same end surface of the fixed trough 1 , the drainage trough 2 , the sedimentation trough 3 and the partition 4 . A sealing edge groove 26 cooperating with the sealing flange 25 is also opened on the same end surface of the fixed trough 1 , the drainage trough 2 , the sedimentation trough 3 and the partition 4 .

[0042] A specific application of this embodiment is: when in use, the fixed groove 1 is buried on both sides of the bridge deck so that the top end surface of the fixed groove 1 is slightly lower than the bridge deck height or flush with the bridge deck height. In order to prevent pedestrians or vehicles on the bridge deck from falling into the fixed groove 1, a protective grille can be installed on the top end surface of the fixed groove 1 according to the existing technology. Several fixed grooves 1 are connected to each other and arranged along the direction of the bridge deck. On rainy days, the water on the bridge deck will flow to both sides of the bridge deck, and then enter the drainage groove 2 installed inside the fixed groove 1. Through several interconnected drainage grooves 2, the water on the bridge deck will flow to the sides of the bridge deck. The water flows away. When a certain section of the drainage structure is blocked due to the accumulation of sediment, the water level inside the fixed trough 1 will gradually rise, and finally enter the buoyancy chamber 5 through the water inlet trough 11. The water flows inside the buoyancy chamber 5 to make the buoyancy seat 7 float up, and then drives the support frame 10 and the sealing strip 11 to move upward through the top rod 8 and the connecting plate 9. The upward moving sealing strip 11 releases the seal on the lower sand trough 12, and the blocked sediment is accompanied by the water flow through the lower sand trough 12 into the sedimentation tank 3, so that the drainage trough 2 remains unobstructed.

[0043] After the water flow is completely drained, the water inside the buoyancy chamber 5 is drained through the drain valve 31, and the buoyancy seat 7 sinks with the drainage of the water flow, thereby driving the top rod 8, the connecting plate 9, the support frame 10, and the sealing strip 11 to sink. Finally, the sealing strip 11 is matched with the lower sand trough 12 to seal the lower sand trough 12. Specific embodiment two:

[0045] Based on the first specific embodiment, the difference of this embodiment is that:

[0046] like Figure 8 、 10 As shown, a sand outlet 13 is formed at the bottom of the drainage trough 2, and an arc-shaped sealing plate 14 is provided on the sand outlet 13. The arc-shaped sealing plate 14 is concentric with the arc-shaped bottom of the settling trough 3. A screw rod 15 and a guide rod 16 are threadedly connected to the bottom of the arc-shaped sealing plate 14. One end of the screw rod 15 passes through the fixed groove 1 and is rotatably connected to the fixed groove 1. An internally threaded sleeve 27, which is threadedly connected to the screw rod 15, is fixed to the bottom of the arc-shaped sealing plate 14. A limit ring 28, which is slidably connected to the guide rod 16, is fixed to the bottom of the arc-shaped sealing plate 14 and the bottom of the settling trough 3.

[0047] like Figure 1 、 3 As shown in Figures 5 and 6, a first bevel gear 17 is fixed to one end of the screw rod 15 outside the fixed groove 1. A rotating shaft 18 is rotatably connected to one side of the fixed groove 1. A second bevel gear 19 is fixed to the bottom end of the rotating shaft 18 and is connected to the core of the first bevel gear 17. A supporting plate 29 that cooperates with the rotating shaft 18 is fixed to one side of the fixed groove 1. The rotating shaft 18 passes through the supporting plate 29 and is rotatably connected to the supporting plate 29. An adjusting wheel is fixed to the top of the rotating shaft 18, and a limiting ring is sleeved on the rotating shaft 18, the bottom end of which contacts the supporting plate 29.

[0048] like Figure 1 、 3 As shown in Figures 5, 6, and 8, the bottom of the fixed trough 1 is set inclined, and a sand discharge trough 20 is fixed to one side of the inclined bottom of the fixed trough 1, and the sand discharge trough 20 is connected to the sediment collection chamber 6.

[0049] like Figure 2 、 3 As shown, a baffle 21 extending to the bottom of the sand discharge trough 20 passes through the top of the sand discharge trough 20, and a pull rod 22 is fixed to one end of the baffle 21 located outside the sand discharge trough 20. The end of the pull rod 22 away from the baffle 21 extends to the top of the fixed trough 1.

[0050] A pull block is fixed to the top of the pull rod 22, and a limit plate 23 passed through by the pull rod 22 is fixed to the fixing groove 1. A spring 24 is sleeved on the pull rod 22, one end of the spring 24 is pressed against the baffle 21, and the other end of the spring 24 is pressed against the limit plate 23.

[0051] After the drainage work is completed, the sediment deposited inside the sedimentation tank 3 needs to be cleaned to facilitate the next use. At this time, the second bevel gear 19 is driven to rotate by rotating the rotating shaft 18. The second bevel gear 19 drives the screw 15 to rotate by engaging with the first bevel gear 17. The rotation of the screw 15 drives the arc-shaped sealing plate 14 to gradually move out of the sand outlet 13, so that the sediment settled inside the sedimentation tank 13 and part of the water flow enter the sediment collection chamber 6 through the sand outlet 13. When it is necessary to remove the sediment, it is only necessary to manually pull up the pull rod 22. The pull rod 22 drives the baffle 21 to release the seal on the sand discharge trough 20, so that the sand discharge trough 20 can be connected with the sediment collection chamber 6, so that the sediment is discharged from the sediment collection chamber 6 with the water flow, and the sand discharge and cleaning work is completed.
