Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to an ultra-high rubber dam. Background Technique

[0002] The rubber dam project is a new type of sluice for water retaining and discharging, and is widely used in many fields such as water conservancy, tourism, shipping, seaports and landscape gardening.

[0003] The rubber dam is easy to construct, and the construction, operation and maintenance costs are relatively low. However, the rubber dam belongs to a flexible thin-walled structure and is prone to wear during operation. Especially when retaining water and overflowing, it is prone to vibration and wear, and is also easily punctured and torn by floating trees and stones in the river, resulting in dam break and causing disaster accidents. During the process of the rubber dam collapsing, a small amount of water remaining in the dam bag is wrapped by the dam bag downstream of the dam axis and is difficult to discharge, forming a small dam water blocking phenomenon, which is not conducive to flood discharge in the river channel. When the water levels upstream and downstream of the rubber dam are both high, the dam bag will float under the action of buoyancy and is not easy to collapse flat, which also affects flood discharge. Limited by the strength of the dam bag rubber material and the conditions of filling and draining water, etc., the designed dam height of the rubber dam generally does not exceed 5 meters, and it is impossible to retain water at a high water level. For the river estuary with a relatively high tidal level, the goal of tide blocking cannot be achieved, and it is not conducive to high-head power generation.

[0004] In the prior art, in order to increase the water storage height, mainly structural forms such as combining high and low sluice dams, double-layer rubber dams with inner liners, steel wire rubber dams, mother-child rubber dams, and pneumatic shield dams are adopted to increase the height of the rubber dam and achieve ultra-high water retaining.

[0005] If the method of combining high and low sluice dams alternately is adopted, using the gate to retain water at a high level and raising the rubber dam bottom plate, high-level water retaining can also be achieved. However, using this method, not only two sets of control devices, namely a hoist and a filling and draining water pump or an air compressor, need to be equipped simultaneously to control the lifting of the gate and the rubber dam, increasing the project investment and making the operation and management cumbersome and complex, but also raising the rubber dam bottom plate will reduce the river channel cross-section for water flow, which is not conducive to flood discharge and is also prone to sediment deposition.

[0006] If double-layer rubber dams with inner liners, steel wire rubber dams and mother-child rubber dams are adopted, it will increase the production and manufacturing difficulty and the construction and installation cost, and the failure rate is very high during operation, and the maintenance difficulty is relatively large.

[0007] If a pneumatic shield dam is adopted, sundries are easily accumulated on the backwater side, thus damaging the inflated dam bag. During flood discharge, sediment will be washed to the backwater side of the pneumatic shield dam, causing the gate plate to jam and unable to collapse flat completely, affecting the river flood discharge. Moreover, the inflation medium of the pneumatic shield dam is air. Compared with water, the molecular spacing is large and the compressibility is large. It is still possible to control the gate plate with a relatively low height, but it is difficult to control the lifting of the gate plate with a relatively large height.

[0008] For the above reasons, the existing structural forms of rubber dams all have various drawbacks, making it difficult to construct ultra-high rubber dams over 5 meters. There is an urgent need to develop an ultra-high rubber dam that is easy to build, requires less investment, and is simple to operate and manage. Content of the Utility Model

[0009] To solve the above problems, the present utility model provides an ultra-high rubber sluice dam. The technical solution of the present utility model is as follows:

[0010] The sluice chamber section of the ultra-high rubber sluice dam is composed of a water retaining gate panel, a hinge shaft, an upstream dam bag, a downstream dam bag, a bottom slab, a left bank pier wall, a right bank pier wall, and a monitoring and control system. It is characterized in that a bottom slab is constructed at the dam site. The water retaining gate panel is located on the upper side of the bottom slab and is connected to the bottom slab through a hinge shaft. The upstream side of the water retaining gate panel is the upstream dam bag, and the upstream dam bag is double-line anchored, with one side anchored to the bottom slab and the other side anchored to the water retaining gate panel. The downstream side of the water retaining gate panel is the downstream dam bag, and the downstream dam bag is anchored to the bottom slab on one side and the water retaining gate panel on the other side. The left and right bank pier walls are at both ends of the water retaining gate panel and the rubber dam bag. The monitoring and control system is connected to the upstream and downstream dam bags and the water retaining gate panel through pipelines buried in the bottom slab.

[0011] The ultra-high rubber sluice dam is characterized in that the upstream and downstream sides of the water retaining gate panel are water-filled rubber dam bags. The upstream and downstream dam bags are inflated simultaneously, and the water retaining gate panel is erected by the water pressure in the dam bags to retain water. The downstream dam bag and the upstream dam bag are drained and collapsed successively, and the water retaining gate panel is then laid down for flood discharge. The height of the erected water retaining gate panel should be higher than the height of the inflated dam bag. The erected angle of the water retaining gate panel can be controlled by controlling the water filling volume of the upstream and downstream dam bags, so as to achieve the goal of the ultra-high rubber sluice dam retaining water at high water levels and collapsing the dam for flood discharge.

[0012] The water retaining gate panel is rectangular and can be made of metal or other high-strength materials. The water retaining gate panel is connected to the bottom slab through a hinge shaft and can rotate around the hinge shaft to be erected, laid down, and rotated at any angle. The height of the erected water retaining gate panel should be higher than the height of the inflated dam bag. Further, in order to enhance the bending stiffness of the water retaining gate panel, the inner side of the water retaining gate panel is set as a hollow structure, and there are multiple reinforcing ribs perpendicular to the hinge shaft inside.

[0013] The hinge shaft includes a base, a bearing, and a fixing bolt. The base is connected to the water retaining gate panel through a bearing and is fixed in the base groove of the bottom slab through a fixing bolt. In order to prevent water from leaking between the upstream and downstream dam bags through the hinge shaft, water stops are provided on both sides of the hinge shaft.

[0014] The upstream dam bag and the downstream dam bag are respectively located on the bottom plates on the upstream side and the downstream side of the water retaining gate board, and are symmetrically arranged. The materials of the upstream and downstream dam bags are multi-layer rubberized fabrics with rubber layers on the inside and outside and fiber woven fabrics pressed in the middle. One end of the dam bag rubberized fabric is anchored to the water retaining gate board, and the other end is anchored to the bottom plate. By filling water into the upstream and downstream dam bags to make them expand, the water retaining gate board is supported and erected to block water; or by draining water outwards to make them collapse and deflate, the water retaining gate board is laid down to discharge flood. The upstream dam bag and the downstream dam bag need to be inflated or deflated synergistically to jointly control the erection, laying down or adjustment of the inclination angle of the water retaining gate board. The two end parts of the upstream dam bag and the downstream dam bag are fan-shaped dam heads. The two radius sides of the fan-shaped dam heads are anchored to the bottom plate and the water retaining gate board, and the arc sides of the fan-shaped dam heads are not anchored. To ensure that the arc length L of the dam bag along the arc is equal to twice the radius after the water retaining gate board is laid down.

[0015] Further, to improve the support and control efficiency of the upstream and downstream dam bags when inflated on the water retaining gate board, the fan-shaped cylindrical bodies of the upstream and downstream dam bags are evenly divided into multi-petal fan-shaped cylindrical dam bags along the hinge axis direction, namely the upper dam bag, the middle dam bag and the lower dam bag, and the water filling amount is controlled by filling water and draining water respectively, so as to control the opening angle and height of the water retaining gate board. The water inlet and outlet with a water cap buried on the bottom plate is used to fill water and drain water for the lower dam bag. A flexible, bendable and compressible pipe led out from the bottom plate in parallel with the water inlet and outlet is used to fill water and drain water for the middle dam bag and the upper dam bag.

[0016] The bottom plate is the foundation of the super-high rubber dam, and is built with concrete, reinforced concrete or masonry.

[0017] The pier wall is a vertical wall that is located at both ends of the water retaining gate board and the rubber dam bag and jointly blocks water with the water retaining gate board. It is connected to the bottom plate and is divided into the left bank pier wall and the right bank pier wall, and is built with concrete, reinforced concrete or masonry.

[0018] The monitoring and control system is a system that monitors the operation data of the super-high rubber dam, fills and drains water for the upstream and downstream dam bags, and thus controls the super-high rubber dam to stand up to block water and lie down to discharge flood. It mainly includes power distribution facilities, monitoring facilities, water filling and draining power facilities, water filling and draining pipelines, control facilities, and safety insurance facilities. The power distribution facilities are power supply and power transformation and distribution facilities. The monitoring facilities are various video monitors, sensors, etc., which are used to monitor the water levels upstream and downstream of the super-high rubber dam, the opening angle and height of the water retaining gate board, and the internal pressure of the upstream and downstream dam bags. The water filling and draining power facilities are water pumps. The water filling and draining pipelines are pipelines for filling water and draining water for the upstream and downstream dam bags. The control facilities are automatic control cabinets. The safety insurance facilities are overpressure alarms and overpressure overflow pipes, which prevent the internal pressure of the upstream and downstream dam bags from being too large and damaged after overfilling.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] (1) The water retaining gate can increase the water retaining height of the rubber dam bag. The super-high rubber dam can achieve water retaining at a super-high water level with a dam height exceeding 5 meters, and can be used in situations such as tide blocking and power generation that require water retaining at a super-high water level.

[0021] (2) It can retain water in both directions and drain water by tipping in both directions. It can not only store river water but also discharge flood water in the river course. At the same time, it can also block the sea tide and prevent seawater from flowing back.

[0022] (3) When the super-high rubber dam overflows, the part impacted by the top-layer water flow is the sturdy and wear-resistant water retaining gate. Large pieces of sand and gravel can pass over the dam safely. The relatively fragile rubber dam bag is in the bottom-layer water flow, thus avoiding being impacted and damaged by waves, ice floes, and sharp and large floating objects, and being protected, which can extend the service life of the rubber dam bag.

[0023] (4) Both sides of the super-high rubber dam have rubber dam bags as supports and buffers, with strong robustness, good seismic performance, and strong resistance to sea waves and typhoons. It is applicable to projects such as coastal storm surge blocking, reservoir spillway regulating sluices, and mountain river flood interception and flood discharge.

[0024] (5) Both the upstream and downstream sides of the super-high rubber dam are enclosed by double-line anchored rubber dam bags. It is not easy for sediment to enter and accumulate at the lower part of the dam, avoiding the phenomena of dam bag wear and dam opening and closing jamming.

[0025] (6) The super-high rubber dam is not restricted by the single-span span and can build large-span dams.

[0026] (7) When the super-high rubber dam retains water and overflows, it is not easy to vibrate and slap, avoiding tearing and dam breakage due to vibration wear.

[0027] (8) The super-high rubber dam can raise and lower the dam quickly, is flexible, and can adjust the opening height arbitrarily according to the project needs, facilitating the control of water level and flow rate.

[0028] (9) When the super-high rubber dam is laid flat, it completely adheres to the bottom plate without blocking water, which is beneficial to flood passage.

[0029] (10) The engineering structure of the two-way water retaining dam is reasonably stressed, not easy to produce stress concentration, can give full play to the mechanical properties and advantages of hard materials and flexible materials, the opening and closing equipment has a simple structure, low construction difficulty, small investment, and is convenient for operation, maintenance and management, so as to achieve the purpose of saving investment and improving project benefits.

Specific implementation manners

[0041] The present utility model provides a super - high rubber dam, which is applicable to projects such as coastal storm - surge prevention, reservoir spillway sluice, and mountain - river flood interception and discharge. The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0042] The gate chamber section of the super - high rubber dam is composed of a water - retaining gate plate 1, a hinge shaft 2, an upstream dam bag 3, a downstream dam bag 4, a bottom slab 5, a left - bank pier wall 6, a right - bank pier wall 7, and a monitoring and control system 8. As Figure 1 、 2As shown in the figure. It is characterized in that a bottom plate 5 is constructed at the dam site. The water retaining gate plate 1 is located on the upper side of the bottom plate 5 and is connected to the bottom plate 5 through a hinge shaft 2. The upstream side of the water retaining gate plate 1 is the upstream dam bag 3. The upstream dam bag 3 is double-line anchored, with one side anchored to the bottom plate 5 and the other side anchored to the water retaining gate plate 1. The downstream side of the water retaining gate plate 1 is the downstream dam bag 4. One side of the downstream dam bag 4 is anchored to the bottom plate 5 and the other side is anchored to the water retaining gate plate 1. At both ends of the water retaining gate plate 1 and the rubber dam bag are the left bank pier wall 6 and the right bank pier wall 7. The monitoring and control system 8 is connected to the upstream and downstream dam bags and the water retaining gate plate 1 through pipelines buried in the bottom plate 5.

[0043] The ultra-high rubber dam is characterized in that the upstream and downstream sides of the water retaining gate plate 1 are water-filled rubber dam bags. The upstream and downstream dam bags are inflated simultaneously, and the water retaining gate plate 1 is erected by the water pressure in the dam bags to retain water. The downstream dam bag 4 and the upstream dam bag 3 are drained and collapsed successively, and the water retaining gate plate 1 is then laid down for flood discharge. The height of the water retaining gate plate 1 after erection should be higher than the height of the inflated dam bags. The erection angle of the water retaining gate plate 1 can be controlled by controlling the water filling amount of the upstream and downstream dam bags, so as to achieve the goal of retaining water at ultra-high water levels and discharging flood by inverting the dam of the rubber dam.

[0044] The water retaining gate plate 1 is rectangular and can be made of metal or other high-strength materials. The water retaining gate plate 1 is connected to the bottom plate 5 through a hinge shaft 2 and can rotate around the hinge shaft 2 as the center to erect, lay down and rotate at any angle. The height of the water retaining gate plate 1 after erection should be higher than the height of the inflated dam bags. Further, in order to enhance the bending stiffness of the water retaining gate plate 1, the inner side of the water retaining gate plate 1 is provided with a hollow structure and there are multiple reinforcing ribs perpendicular to the hinge shaft 2 inside.

[0045] The hinge shaft 2 includes a base 9, a bearing 10 and a fixing bolt 11. The base 9 is connected to the water retaining gate plate 1 through the bearing 10 and is fixed in the base groove of the bottom plate 5 through the fixing bolt 11. In order to prevent water from leaking between the upstream and downstream dam bags through the hinge shaft 2, water stops 12 are provided on both sides of the hinge shaft 2. As Figure 4 shown.

[0046] The upstream dam bag 3 and the downstream dam bag 4 are respectively located on the bottom plate 5 on the upstream side and the downstream side of the water retaining gate 1, and are symmetrically arranged. The materials of the upstream and downstream dam bags are multi-layer rubberized fabrics with rubber layers on the inside and outside and fiber woven fabrics pressed in the middle. One end of the dam bag rubberized fabric is fixedly connected to the water retaining gate 1, and the other end is fixedly connected to the bottom plate 5. By filling water into the upstream and downstream dam bags to make them expand, the water retaining gate 1 is supported and erected to block water; or by draining water outwards to make them collapse, the water retaining gate 1 is laid down to discharge flood. The upstream dam bag 3 and the downstream dam bag 4 need to cooperate to inflate or deflate to jointly control the erection, laying down or adjustment of the inclination angle of the water retaining gate 1. The two side ends of the upstream dam bag 3 and the downstream dam bag 4 are fan-shaped dam heads 13. The two radius sides of the fan-shaped dam head 13 are fixedly connected to the bottom plate and the water retaining gate, and the arc side of the fan-shaped dam head 13 is not fixedly connected. To ensure that the arc length L of the dam bag along the arc is equal to twice the radius after the water retaining gate 1 is laid down.

[0047] Further, to improve the support and control efficiency of the upstream and downstream dam bags when inflated, the fan-shaped cylinders of the upstream and downstream dam bags are evenly divided into multi-petal fan-shaped cylinder dam bags along the hinge axis direction, namely the upper dam bag 14, the middle dam bag 15, and the lower dam bag 16, and the water filling amount is respectively controlled by filling water and draining water, so as to control the opening angle and height of the water retaining gate 1. The water inlet and outlet with a water cap 17 buried on the bottom plate is used to fill water and drain water for the lower dam bag 16. A flexible, bendable and compressible pipe 18 is led out from the bottom plate in parallel with the water inlet and outlet to fill water and drain water for the middle dam bag 15 and the upper dam bag 14. As Figure 3 , Figure 4 shown.

[0048] The bottom plate 5 is the foundation of the super-high rubber dam, and is built by concrete, reinforced concrete or masonry.

[0049] The pier wall is a vertical wall that jointly blocks water with the water retaining gate at both ends of the water retaining gate and the rubber dam bag, and is connected to the bottom plate. It is divided into the left bank pier wall 6 and the right bank pier wall 7, and is built by concrete, reinforced concrete or masonry.

[0050] The monitoring and control system 8 is a system that monitors the operation data of the super-high rubber dam, fills and drains water for the upstream and downstream dam bags, so as to control the super-high rubber dam to stand up to block water and lie down to discharge flood. It mainly includes power distribution facilities, monitoring facilities, filling and draining power facilities, filling and draining pipelines, control facilities, and safety insurance facilities. The power distribution facilities are power supply and power transformation and distribution facilities. The monitoring facilities are various video monitors, sensors, etc., which are used to monitor the water levels upstream and downstream of the super-high rubber dam, the opening angle and height of the water retaining gate 1, and the internal pressure of the upstream and downstream dam bags. The filling and draining power facilities are water pumps. The filling and draining pipelines are pipelines for filling water and draining water for the upstream and downstream dam bags. The control facilities are automatic control cabinets. The safety insurance facilities are overpressure alarms and overpressure overflow pipes to prevent the internal pressure of the upstream and downstream dam bags from being too large and damaged after overfilling.

[0051] AsFigure 5 , Figure 7 , Figure 8 As shown in Figure 8 , the operation procedure of the super-high rubber dam for inverted flat flood discharge is as follows.

[0052] (1) When the dam needs to be inverted for flat flood discharge, start the water filling and drainage power facilities, and first discharge a small amount of water from the downstream dam bag to make it deflated.

[0053] (2) After the downstream water retaining gate 1 tilts towards the downstream side, then utilize the gravity of the water retaining gate 1 and the thrust of the water to discharge the water in the downstream dam bag 4 and the upstream dam bag 3, making the upstream and downstream dam bags deflated.

[0054] (3) The water retaining gate 1 will gradually fall down as the upstream and downstream dam bags collapse, until it lies flat on the bottom plate. As shown in Figure 9 , during the process of discharging the water in the dam bag, the gravity of the water retaining gate 1 and the thrust of the water can be used for self-drainage, or the water filling and drainage power facilities can be started for forced drainage according to needs. The pressure in the upstream and downstream dam bags should be kept relatively balanced. Figure 9 As shown in Figure 9 , during the process of discharging the water in the dam bag, the gravity of the water retaining gate 1 and the thrust of the water can be used for self-drainage, or the water filling and drainage power facilities can be started for forced drainage according to needs. The pressure in the upstream and downstream dam bags should be kept relatively balanced.

[0055] As Figure 5 , Figure 7 , Figure 8 As shown in Figure 5 , the operation procedure of the super-high rubber dam for erecting water retention is as follows.

[0056] (1) When the dam needs to be erected for water retention, first start the water filling and drainage power facilities and slightly inflate the downstream dam bag 4.

[0057] (2) As the downstream dam bag 4 is gradually inflated, the water retaining gate 1 will gradually rise, and then start to inflate the upstream dam bag 3.

[0058] (3) The water retaining gate 1 will gradually stand up as the dam bag is inflated. As shown in Figure 1 , during the process of filling water into the dam bag, the pressure in the upstream and downstream dam bags should be kept relatively balanced, and overpressure inflation of the dam bag is strictly prohibited. Figure 1 , 2 , as shown in 2 and , during the process of filling water into the dam bag, the pressure in the upstream and downstream dam bags should be kept relatively balanced, and overpressure inflation of the dam bag is strictly prohibited.

[0059] When the super-high rubber dam is used for tide blocking and flood discharge with the change of tide level, there is no difference from the operation scheduling procedure of the general tide-blocking dam. It is necessary to adjust the height of the dam with the change of tide level for tide blocking or flood discharge.

[0060] The super-high rubber dam can not only block water in two directions, but also control the flow rate in two directions. When it is necessary to divert water from the downstream to the upstream, it can be adjusted to the Figure 6 style shown in Figure 6 for reverse water diversion.

[0061] The present invention will be further described below in conjunction with Embodiments 1-3.

[0062] Embodiment 1: The super-high rubber check dam is arranged in a single span. The water retaining gate board 1 and the rubber dam bag are provided with abutment walls at both ends. The upstream and downstream of the abutment walls are connected to the river slope protection through twisted or straight wing walls. As Figure 2 shown.

[0063] Embodiment 2: The super-high rubber check dam is arranged in multiple spans. The two ends of the gate chamber section are side piers 19, and the middle part is divided into multiple spans by a plurality of middle piers 20. Each span can independently control the opening angle and height of the water retaining gate board, and independently control the water retaining and water discharging of the rubber check dam. The upstream and downstream of the side piers 19 are connected to the river slope protection through twisted or straight wing walls. As Figure 9 shown.

[0064] Embodiment 3: The super-high rubber check dam is arranged in multiple spans. The two ends of the gate chamber section are side piers 19, and there is no middle pier in the middle part. Each span is connected by water stops. Each span can independently control the opening angle and height of the water retaining gate board 1, and independently control the water retaining and water discharging of the rubber check dam. The upstream and downstream of the side piers are connected to the river slope protection through twisted or straight wing walls. As Figure 10 shown.

[0065] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
