Description

Technical Field

[0001] The present invention relates to a flood control and water blocking device for highway and railway culverts, and particularly to a water blocking or water diversion and guiding device for the entrance of highway bridge culverts made of rubber bladder bags. Background Art

[0002] Currently, for the problem of culvert water accumulation, mainly pumping stations are built to pump and drain the accumulated water, and relevant personnel are arranged to guard on rainy days to block pedestrians and vehicles. This method has the following disadvantages: ① large investment and low efficiency, once it occurs, a large number of drainage equipment and operating personnel need to be invested; ② the intensity, occurrence and duration of rainwater are uncertain, and the timeliness is poor, and it cannot ensure the timely and effective diversion of the accumulated water, and there are still major risks to the life and property safety of pedestrians; ③ due to the uncertainty of rainwater, the effective time of relevant personnel on duty cannot be guaranteed, consuming labor and a large amount of time; ④ due to the scouring of rainwater, a large amount of solid materials such as soil, stones, wood, and surface garbage will be carried and accumulated at the bottom of the culvert, further increasing the manpower and transfer burden. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a fast and effective combination device for quickly blocking water and diverting water in highway and railway culverts to solve the problem of rainwater accumulation in railway and highway culverts on rainy days.

[0004] A fast water blocking, water diversion, opening and closing combination device for highway and railway culverts of the present invention includes foundation pits respectively dug at the entrances and exits of underground culverts. An underground rectangular groove is installed in each of the foundation pits. Collection grooves are respectively excavated at both ends of the road surface at the outer side position of each underground rectangular groove. A retaining member is fixedly installed along the entire length on the bottom wall of each underground rectangular groove on the upstream side of the water flow direction and along the width direction of the underground culvert. The top surface of the retaining member is an arc-shaped top surface. The arc-shaped bottom end of the retaining member abuts against the side wall of the underground rectangular groove on the upstream side of the water flow direction. The retaining member on the downstream side of the water flow direction is fixed on the bottom wall of the underground rectangular groove. A rubber bladder is installed on the arc-shaped top surface. The rubber bladder is located at the arc bottom side of the arc-shaped top surface and is fixedly connected to the bottom wall of the retaining member and the bottom wall of the underground rectangular groove through a plurality of anchoring systems. A charging and discharging port is opened on the rubber bladder. The charging and discharging port is connected to one end of a charging and discharging pipeline. The other end of the charging and discharging pipeline passes through the underground rectangular groove and is connected to an air compressor or a water pump in a ground workstation. A plurality of rubber return belts are connected to the bottom wall of the rubber bladder;

[0005] A trough cover is placed on the top wall of the underground rectangular trough. The trough cover on the upstream side of the water flow direction is hinged to the top of the underground rectangular trough through a hinge hinge. A continuous waterproof rubber sheet is connected between the bottom wall of the trough cover on the upstream side of the water flow direction and the side wall of this side of the underground rectangular trough. Both sides of the waterproof rubber sheet are fixedly and sealedly connected to the bottom wall of the trough cover and the inner wall of the underground rectangular trough respectively. When the trough cover rotates upward around the hinge hinge under the support of the rubber bladder, the waterproof rubber sheet can be set to closely adhere to the intersection of the trough cover and the underground rectangular trough to waterproof and seal the underground rectangular trough, and the water intercepted on the trough cover can flow into the water collecting trough along both sides of the trough cover. A plurality of chains are hingedly connected between the bottom wall of the trough cover on the downstream side of the water flow direction and the side wall of this side of the underground rectangular trough.

[0006] The beneficial effects of the present invention are as follows:

[0007] 1. Low cost, simple structural design of each component, convenient production, convenient construction, short construction period and recyclable.

[0008] 2. When facing a large rainwater flow, only one person can quickly complete the water blocking and drainage operation, with good timeliness, no need for multiple pumping and transfer of accumulated debris in the tunnel, saving the input of personnel and machinery.

[0009] 3. The rubber bladder can be filled to different degrees according to the amount of rainfall, and the rotation of the trough cover driven by it can resist rainwater of different flow rates. The degree of elevation of the trough cover will also play a certain warning role for passing pedestrians and vehicles.

[0010] 4. After the danger, after exhausting the air or water in the rubber bladder, the rubber bladder can be automatically recovered into the arc trough, and the trough cover automatically returns to the original ground, without affecting normal passage, with significant economic benefits.

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0019] As shown in the accompanying drawings, a combined opening and closing device for rapid water blocking and drainage of highway and railway culverts according to the present invention is respectively located at the entrances and exits of the underground culvert 18-2. Road surface excavation is respectively carried out at the entrances and exits, and then the underground rectangular trough 4 is built and installed in the excavated trough. The highway or railway 18-1 is directly above the culvert 18-2. Catch basins 18-3 are respectively excavated on the road surface 1 on the left and right sides of each of the underground rectangular troughs on the upstream side of the water flow direction 17, and the underground drainage pipelines are connected through the catch basins 18-3 for discharging water.

[0020] A quick water-blocking, drainage, opening and closing combined device for highway and railway culverts according to the present invention includes foundation pits respectively dug at the entrances and exits of the underground culvert 18-2. An underground rectangular groove 4 is installed in each of the foundation pits. Catch basins 18-3 are respectively dug on both sides of the road surface 1 at the outer side position of each of the underground rectangular grooves 4. A retaining member 7 is fixedly installed along the entire length in the width direction of the underground culvert on the bottom wall of each underground rectangular groove 4 on the upstream side of the water flow direction 17. The top surface of the retaining member 7 is an arc-shaped top surface. The arc bottom end of the arc-shaped top surface of the retaining member 7 abuts against the side wall of the underground rectangular groove 4 on the upstream side of the water flow direction 17. The retaining member 7 on the downstream side of the water flow direction 17 is fixed to the bottom wall of the underground rectangular groove 4 by fixing bolts 9. A rubber bladder 10 is installed on the arc-shaped top surface. The rubber bladder 10 is fixedly connected to the bottom wall of the retaining member 7 and the bottom wall of the underground rectangular groove 4 through a plurality of anchoring systems 16 at the arc bottom side of the arc-shaped top surface. An air and water filling and discharging port 12 is opened on the rubber bladder 10. The rubber bladder 10 is inflated or filled with water through the air and water filling and discharging port 12. The air and water filling and discharging port 12 is connected to one end of an air and water filling and discharging pipeline. The other end of the air and water filling and discharging pipeline passes through the underground rectangular groove 4 and is connected to an air compressor or a water pump in a ground workstation for filling the rubber bladder 10 with water or inflating it. A plurality of rubber reset straps 11 are connected to the bottom wall of the rubber bladder 10. After the rubber bladder 10 completes water blocking, it is supported on the retaining member 7 under the traction of the rubber reset straps 11.

[0021] As a preferred embodiment of the present invention, each of the anchoring systems 16 includes an upper clamping member and a water-stop sponge sheet 16-6. The rubber bladder 10 is clamped between the upper clamping member and the water-stop sponge sheet 16-6. The upper clamping member includes a stainless steel washer 16-2, a bottom plate 16-7 of a protective plate, an upper pressing plate 16-4 and a rubber gasket 16-5 arranged in sequence from top to bottom. The rubber bladder 10 is fixedly connected to each other through screws 16-1 that sequentially pass through the upper clamping member, the rubber bladder 10, the water-stop sponge sheet 16-6, the retaining member 7 and the bottom wall of the underground rectangular groove 4. The protective plate is connected by a flat hinge 16-8 between an arc-shaped top plate 16-3 and a bottom plate 16-7. The arc-shaped top plate 16-3 is located above the screw 16-1 to prevent the rubber bladder 10 from being worn and damaged by the screw 16-1 during use.

[0022] A groove cover 5 is covered on the top wall of the underground rectangular groove 4. The groove cover 5 on the upstream side of the water flow direction 17 is connected to the top of the underground rectangular groove through a hinge hinge 13. The bottom wall of the groove cover 5 adopts a door nail button structure 6 to increase the resistance between the rubber bladder 10 and the bottom wall of the groove cover 5 and prevent the groove cover 5 from wearing and rupturing the rubber bladder 10 during repeated rotation.

[0023] On the upstream side of the water flow direction 17, a continuous waterproof rubber sheet 14 is connected between the bottom wall of the said trough cover 5 and the side wall of the underground rectangular trough on this side. Both sides of the said waterproof rubber sheet 14 can be fixedly connected to the bottom wall of the trough cover 5 and the inner wall of the underground rectangular trough respectively by screws 15. When the said trough cover 5 rotates upward around the hinge hinge 13 under the support of the rubber bladder 10, the said waterproof rubber sheet 14 can be arranged closely against the intersection of the trough cover 5 and the underground rectangular trough 4 to seal the underground rectangular trough 4 and prevent rainwater from entering the culvert through the underground rectangular trough. The water flow intercepted on the trough cover 5 can flow along the trough cover 5 to both sides and into the water collecting trough 18 - 3.

[0024] On the downstream side of the water flow direction 17, a plurality of chains 8 are hingedly connected between the bottom wall of the said trough cover 5 and the side wall of the underground rectangular trough on this side. Each of the said chains can include a plurality of lightweight alloy sheets. The plurality of lightweight alloy sheets are hinged by flat hinge joints. The two ends of the hinged lightweight alloy sheets can be fixedly connected to the bottom wall of the trough cover 5 and the side wall of the underground rectangular trough respectively through connectors 3. The size of the hinged lightweight alloy sheets can be determined according to the rotation angle of the trough cover.

[0025] The said chains are mainly used to limit the rotation amplitude of the trough cover 5, as well as for pedestrian and vehicle passage and to protect the rubber bladder 10 in the underground rectangular trough 4; preferably, a buffer rubber pad 2 is installed on the top wall of the side wall of the underground rectangular trough 4 on the downstream side of the water flow direction 17, so that there is a buffer and vibration reduction effect between the end of the trough cover 5 and the trough wall during the opening and closing process of the device.

[0026] The rubber bladder 10 installed in the said underground rectangular trough 4 is filled by an air compressor or a water pump. After the rubber bladder 10 bulges, it drives the trough cover 5 to rotate. When blocking water, the water flow will gather along the water-facing side of the trough cover 5 to both sides of the water collecting trough 18 - 3. The said trough cover 5 acts as a water-blocking dam to divert the water flow to the water collecting troughs 18 - 3 on both sides of the road, and the water collecting troughs are connected to the sewage drainage channel for drainage.

[0027] The construction method of this system is as follows:

[0028] 1. The quick water-blocking and drainage opening and closing combined device should be respectively arranged at the entrances and exits of the underground culvert 18 - 2. Excavation and construction of the underground rectangular trough 4 should be carried out at the said entrances and exits, as Figure 1 shown. Excavation should be carried out at both ends of the road surface at the position of the said underground rectangular trough 4 to respectively construct the water collecting troughs 18 - 3, as Figure 7 shown. Then the water collecting troughs 18 - 3 are connected to the underground drainage pipeline for water discharge.

[0029] 2. Fix the retaining support 7 to the bottom plate of the underground rectangular trough 4 through the anchor bolts 9. Secondly, fix the rubber bladder 10 through the anchoring system 16 (such as Figure 2is fixed on the bottom plate of the underground rectangular groove 4. Finally, on the upstream side of the water flow direction 17, the groove cover 5 is hinged to the groove wall of the underground rectangular groove 4, and a waterproof rubber sheet 14 is used for sealing at the joint, as Figure 2 shown;

[0030] 3. Pre-fill the rubber bladder 10 and check whether there is air leakage or water leakage in the rubber bladder. After ensuring it is intact, drain the air or water in the rubber bladder. On the downstream side of the water flow direction 17, use the connecting piece 3 to connect the chain 8 to the end of the groove cover 5 and the groove wall of the underground rectangular groove 4 respectively, as Figure 2 shown;

[0031] 3. When the rainfall is small, to increase the passing rate of the culvert in rainy weather, the filled rubber bladder 10 drives the groove cover 5 to rotate to an appropriate height as Figure 4 shown. At this time, pedestrians and vehicles can pass through the groove cover 5 smoothly. When pedestrians and vehicles are above the groove cover 5, the filled rubber bladder 10 is deformed by the ground pedestrian and vehicle loads and is completely located in the underground rectangular groove 4. The chain 8 is automatically retracted into the underground rectangular groove, and the groove cover 5 remains flush with the ground as Figure 5 shown. After the pedestrians and vehicles pass, the squeezed and filled rubber bladder 10 slowly returns to its initial state and at the same time drives the groove cover 5 to rotate to the original appropriate water-blocking height, restoring the water-blocking and drainage functions, as Figure 4 shown.

[0032] 4. When the rainfall is large, increase the filling degree of the rubber bladder to continue to raise the height of the groove cover 5 to reach the maximum water-blocking state as Figure 6 shown. At this time, pedestrians and vehicles are prohibited from passing.

[0033] 5. After the culvert interception and diversion are completed, gradually drain all the air or water inside the rubber bladder. The rubber bladder is stored in the arc groove under the traction of the rubber reset belt. The groove cover 5 automatically returns to the original road surface under its own weight, and the culvert can pass normally. When the next rain comes, first check the sealing performance of the rubber bladder, and then repeatedly use the above steps for water-blocking or water diversion.
