Sand discharge and silt disturbance device for reservoir overflow weir, spillway and sediment discharge tunnel

The creation department is directed to installing at least one fixed submersible water jet jet mud disturbance device at a suitable position of a reservoir hydraulic structure such as a reservoir overflow raft, a spillway surface or a sediment discharge tunnel; On the hydraulic structures of reservoir spill or flood discharge, flood discharge, and sediment discharge, select suitable locations, set up hydraulic machinery such as waterjet jets, and extend the pipeline power supply to the upper land control room. When the reservoir needs flood discharge or overflow When flooding, flood discharge, and sediment discharge, in conjunction with the initiation of this creation, the three-dimensional streamlined fluidic zone will be accumulated in the overflow raft, the spillway, the vestibule of the sediment discharge tunnel and the reservoir discharge, flood discharge and sediment discharge. The sludge in the belt is disturbed by high-pressure equipment such as high-pressure water column and high-speed agitator, and the special turmoil of the spillway, sediment discharge tunnel and other vestibules has the special space function - neutralization and dilution hydraulic suction and discharge, and the reservoir overflows and discharges sand. The silt cracking of the consolidation of the reservoir bed near the vestibule of the facility, through the free flow, gravity flow discharge flow rate, flow sling, thick slag cement slurry continues to flow down the torrent and into the spillway, sand discharge The flood discharge tunnel is safely and harmlessly discharged, and the effective disturbance of sludge in front of the dam and the key areas is eliminated. It can be placed in the three-dimensional streamlined flow zone when the reservoir overflows, and the pressure water pipe is arranged on the silt surface to the sludge high pressure. The jet can also be connected to the anchoring work pontoon to hang the device to expand the sand discharge area; use the torrent, use the effluent water to simultaneously discharge the sand, and effectively reduce the siltation elevation before the dam.

The original creation device, which is fixed under the surface of the hydraulic structure of the spillway, spillway and sediment discharge tunnel, has high operational safety and can be operated all day in the worst weather. The platform of the device can be selected according to the environmental facilities of each reservoir. The pipeline power extension tube suitable for installation and operation can be extended to the shore control room and operated by remote control buttons.

The main technical knowledge areas of this creation: (1) The equipment for the drainage and flood discharge of the reservoir, the spillway tunnel, the sediment discharge method and the silt disturbance (high-pressure submersible pump and high-speed agitator, etc.) Spillway, overflow, sand discharge, The appropriate position of the flooding structure; the reverse installation of the high-pressure wear-resistant submerged pump, the downward distribution of the outlet pressure water pipe to the target area of the sludge, and the high-pressure water column directly aligned with the sludge accumulated in the vestibule, supplemented by a stirrer When the high-pressure equipment is stirred, the silt impact stirrer will be crushed, cracked, and floated. Combined with the free-flow and gravity-flow special space functions of the overflow weir, the spillway, and the sediment discharge tunnel, all the silt will be neutralized and diluted. Suction and discharge, will not pollute the water body, will not float the water surface, will not return to the bottom of the reservoir, the equipment device is fixed under the water surface of the spillway diversion wall or the vertical front edge of the overflow weir, the appropriate position of the drainage channel of the sand discharge channel, the control line The extension is installed on the land button remote control, the safety of the facilities and operators is improved, and it can be safely operated under the worst typhoon and heavy rain. (2) When using the spillway and flood discharge in the reservoir, the water flow is affected by the environmental topography and the position of the water outlet, which presents a three-dimensional streamlined flow state (meaning that the water flow trough is sequentially drifting to the downstream overflow, discharge, and discharge). In this zone, 1. Place a pressure water pipe and a jet port on the silt surface under the surface of the water to cause a jet of high-pressure water. 2. Set up the working floating platform on the water surface, use the flow characteristics to hang the device, and simultaneously carry out the dredging and sedimentation to expand the sand discharge effect. (3) Using the hydraulic drainage mechanism of the reservoir to introduce the outlet end of the silt conduit into the flood discharge and sediment discharge in the reservoir silt accumulation area by traditional mud pumping, water surface, bottom of the reservoir, mud transporting method, and flood discharge of the reservoir. The vestibule of the facility increases the sediment carrying capacity of the hydrological sedimentation, and uses the special hydraulic functions such as gravity flow, free flow, and nozzle flow when the above-mentioned facilities discharge water and discharge water, and the sludge is neutralized and diluted.

According to the current middle and lower parts of the reservoir dam in Taiwan, there are small drainage workers, which are used for normal or flooding operation, and also used as a micro-discharge drowning water. However, there is no large-scale platoon dedicated to the bottom of the reservoir. Sand passages, such as Zengwen, Shimen, Wushe, Wushantou Reservoir; the reservoir has been silt up for decades since the reservoir was operated, and it has even been higher than the water intake. Therefore, it can only be used by the existing water intake and outlet. The regulation and operation of the gate maneuvering; the simple effect of water discharge has the limit of hydraulic drainage, and it can only be reluctant Keep the minimum opening of the bell mouth before the drain, and the clearance of the pole block. However, in case of heavy typhoon and heavy rain, there is a lack of emergency response capability. It may be deposited 5-6 meters in front of the dam, and then the water inlet will be It may be blocked by silt branches, causing the reservoir to fail to operate properly and releasing water, which is extremely risky.

Although it is used to cooperate with waterjets, air compressors and diving equipment, and personnel to operate underwater, to disturb the silt before the water inlet, although it can improve the problem of removing the wood and bamboo garbage in front of the water inlet, the current technology and experience of Shimen Reservoir If there is a need to clear the mud before the hole, there are still many blind spots that cannot be overcome; if the equipment mobilizes recovery costs, high risk, high unit price, inconvenient operation, small amount, intermittent, intermittent, complicated and difficult, waste valuable water, this Underwater operation method is limited to the surface of the water and storm, and can only be applied to the emergency rescue of the operation and operation of the reservoir. It is not economical, efficient, easy to operate, and a large number of continuous, simple and feasible reservoirs in front of the dam. The overflow overflow of the overflow, the spillway with the gate opening and closing, and the accumulated silt of the flood discharge tunnel and the vestibule of the drainage gate are allowed to be accumulated. How to effectively remove it has not been mentioned so far.

The creator engaged in the operation of the reservoir for several decades. At the moment when the reservoir in Taiwan faced serious siltation, but there was no effective siltation countermeasure, the concept of multiple dredging and sediment removal should be brought up. Take the Nanhua Reservoir as an example. The reservoir is Natural overflow flood discharge reservoir, when the typhoon torrential rain and mud flow into the reservoir, but overflowing is a faint light water, the reservoir becomes a typical large sedimentation pond; however, each time the flood comes, There are natural floods of 6-10 days, and an average of about 56 days of flooding opportunities per year. If you can effectively use this precious natural spillover opportunity, it will be deposited in the vestibule of the spillway and sand discharge tunnel in front of the dam. The massive mud disturbs up and rises, forming a high-concentration type of water, with the huge flow velocity of the overflow hydraulic force flowing out, achieving the purpose of efficiently removing reservoir siltation, the so-called artificial value-added efficiency of hydraulic drainage concept That is the focus of thinking about the creation of this creation.

The reason is that the main purpose of this creation is to support the construction method of the front and the bottom of the reservoir for water drainage, and to install a fixed submersible (waterjet jet) silt agitation device, which is a floating platform and a submersible underwater operation. And the advantages of various types of dredging, such as siphon dredging, suction dredger, and reference sewage plant sedimentation tank, and improve their shortcomings. Application innovations are provided in reservoir overflow weirs, spillways, flood discharge tunnels (concrete Appropriate position of structure and facilities, set fixed submersible (water jet jet) silt disturbance device, when the reservoir is in the flood discharge, flood discharge or sediment discharge tunnel, the device can be activated at the same time by button. Automatic operation, with high-pressure water column and high-speed agitator and other high-pressure equipment, aiming at the target area of the vestibule silt in the overflow weir, spillway and flood discharge channel, breaking the silt surface of the accumulated silt, causing it to break up and borrow The overflow weir, the spillway, and the sediment discharge tunnel have the special space function of free flow or gravity flow - the disturbed sludge, the neutralization and dilution principle and the hydraulic suction and discharge function, the spillway, the sediment discharge tunnel, and the dam front The puddles formed by the silt are all discharged instantaneously, and can be placed in the three-dimensional streamlined flow zone at the front end of the above-mentioned facility and the reservoir for flood discharge and sediment discharge. The water pressure water pipe and the water spout are laid down in the silt surface. Produce high-pressure jet water flow, disturb the sludge, and also anchor the floating work platform to hang the equipment, expand the spilled sand area, ensure that the water inlet will never be blocked by mud, and will not pollute the reservoir water body, which can be used in any best sand discharge. Timing operation at any time, increasing the amount of sand discharged, ensuring the safety of sand-discharging operators and equipment, easy operation, saving investment, saving materials and labor.

The creative method and installations will be used in the natural flooding or flood discharge of the reservoir, or in the discharge and discharge of sand discharge tunnels, and at the same time, taking into account the need for gaining sand. It will become a medium-high-year reservoir-sludged serious reservoir, effectively dredging, and the water gate equipment is preserved. One of the necessary equipment.

In order to let your review board have a better understanding of this creation, Zize elaborated on the creation as follows:

Please refer to the first figure to the fourteenth figure. The creation is at least 11 below the front edge of the reservoir drainage and sediment discharge hydraulic structures (ie, overflow weir, reservoir flood discharge, and sediment discharge engineering facilities). A submersible (water jet jet) silt disturbing device 20, the front end of which is provided with at least one extension pipe 26 to the vestibular silt accumulation zone 30 and a three-dimensional appearance when the reservoir overflows, floods, discharges and discharges The stream zone zone 25 is streamlined to produce jets, high pressure spirals. In addition, along the front edge of the reservoir drainage and drainage structure 10, the pipeline power supply pipe 12 is installed and connected to the shore control room 13 to be operated by a remote control button. With the reservoir drainage and killing hydraulic structure 10 as the center, with the first figure, the second figure and the eighth figure, the water level automatic lifting buoy float cable extension pipe 14 and the vertical fixed anchor seat 15 work together. The platform 16 suspends the submerged mud disturbing device 20, and expands the sand discharging operation area to the vestibular silt accumulation area 30 and the three-dimensional streamlined liquid zone 25 by the remote alignment line 17.

Please refer to the fifth and sixth figures. This creation is at the appropriate position below the front edge of the 10 flood discharge sandway of the reservoir for flood discharge and sedimentation of hydraulic structures (ie, reservoir flood discharge and drainage tunnel entrance). At least one submerged mud disturbance device 20 is installed and installed, and the outlet pipe outlet can be directly sprayed to the vestibule sludge accumulation area 30 of the hole, or can be extended to the vestibular silt accumulation area 30 and the three-dimensional streamline far from the hole. The fluidized zone zone 25 produces a high pressure jet stream and a high pressure spiral wave. In addition, along the flood discharge sand tunnel mouth, the submerged mud disturbance device 20 is equipped with a pipeline power supply extension pipe 12 for operation, and is operated to a remote control button operation in the onshore control room 13. It is centered on the tunnel opening of the reservoir drainage and drainage structure. The working platform 16 is fitted in the vestibular silt accumulation zone 30 and the three-dimensional streamlined liquid zone 25 to suspend the submerged mud disturbance device 20 to expand the sand discharge area.

As shown in the eighth figure, the vertical fixed anchor seat 15 is vertically fixed with the main steel (cable) cable 151 and the vertical fixed auxiliary steel (cable) cable 152 respectively suspended and fixed anchoring 153 above the silt 18; Water level automatic lifting buoy float cable extension tube 14 hanging below The water level is automatically raised and lowered by the buoy 141.

As shown in the first to sixth figures, when the reservoir is naturally flooded or flooded, or when the flood discharge and sediment discharge operations are carried out, the submersible silt disturbance device 20 will be activated to accumulate in the reservoir for flood discharge and sediment discharge. The silt 18 of the vestibule of the facility is strongly disturbed, crushed, cracked, deuterated and raised by the high-pressure water column and the stirrer 19, and the three-dimensional streamlined liquid zone 25 is presented, and the spillway, overflow weir, row The special drainage function of the sand drainage tunnel - neutralization dilution and hydraulic suction and discharge 22, centralized injection of overflow weir, spillway, flood discharge tunnel, sand discharge tunnel gate 23, continuous injection of high concentration sediment and water into the reservoir The flood discharge and drainage hydraulic structure 10 is instantaneously discharged 24 by the flood discharge and drainage channel.

Referring to Figures 15 to 18, the façade of the traditional man-made mud and mud pipe for injection into the flood discharge and sediment discharge facilities will deposit the sediment 18 in the reservoir 1 to sink the water. After the sludge disturbance device 20 is extracted, the water surface pipe 26 is discharged from the water surface or the deposition surface to the vestibule of the reservoir drainage and drainage hydraulic structure 10.

Furthermore, this creation is a new method and device for dredging and sediment removal of reservoir overflow weirs, spillways and sediment discharge tunnels; it is used to operate water discharge and sediment discharge mode during flooding of reservoir facilities, and to overflow overflow, spillway and sediment discharge. The flood discharge tunnel has the special space function of free flow and gravity flow. It can be easily and fully utilized by installing the device at the appropriate position of the overflow weir, spillway and sediment discharge tunnel or by pumping mud and injecting into the vestibule. The excess amount of water required for flood discharge can accurately and effectively eliminate the vestibular silt, and can expand the sand discharge area to improve the sand discharge effect.

Take the Nanhua Reservoir as an example: assuming that every typhoon event occurs, when the reservoir is full of water, the set overflow weir will begin to overflow naturally, and the clear water or faint water will be naturally discharged; but if it is used for sand discharge, In conjunction with the start-up of the system, it is assumed that there will be an overflow of about 8 days for each stormy event. There are about 7 typhoon torrential rain events per year. The estimated energy and dredging efficiency are as follows: the daily siltation and discharge volume is 60,000 m ³ . Dredging sludge discharge amount per 60,000m ³ × 8 Day = 480,000 m ^3. The annual siltation and discharge volume is 480,000 m ³ × 7 times = 3,360,000 m ³ .

Take the Nanhua Reservoir as an example: the flood discharge of the overflow weir is about 5~100CMS, and the sediment concentration is about 2%. The quantity of the method can be adjusted randomly according to the flood discharge. The sediment concentration is about 100,000ppm and the turbidity is about 74,000. NTU, this value is within the allowable sediment concentration range of the downstream rivers and rivers.

1. The creative method and the silt disturbing device are directly installed on the hydraulic structures such as the overflow weir, the spillway diversion wall, the flood discharge tunnel and the sand discharge tunnel under the water surface of the reservoir. The equipment and personnel are safe and easy to operate, as long as The remote control operation of the button on the land control room can be performed.

2. The creation device is fixed, and the outlet pipe is erected downwardly to the target area (can be automatically rotated according to the design, the angle is adjustable), and can be extended to a long distance silt accumulation area such as the vestibule, and can be easily operated with a high pressure water column. Straight contact with impact mud, such as agitator, exempts the platform ship from being unable or difficult to anchor, unable to access the hole, must work underwater, and has the disadvantages of work hazard and short working hours.

3. The waterjet jet device of the present invention can be set in one or more groups according to the purpose, and can also be operated by single item, multiple items, single, multiple groups or simultaneous startup.

4. This creation can add high-pressure air compressor helium to the needs of the creation, strengthen the sediment and improve the efficiency of sand discharge.

5, grasp the worst weather - typhoon rain is also the best time to arrange sand, you can still safely perform sand discharge operations.

6. If there is no creation, separate natural flood or spillway gate operation flood discharge, or separate flood discharge and sand discharge gate for flood discharge and sand discharge operation, the sediment discharge effect is extremely limited. After all, the reservoir is like a super large one. In the sand-sinking pool, most of the sediments in the sediments have been deposited in the middle and upper reaches of the flood. The sand-discharging tunnels can only eliminate a small amount of silt near the sand-discharging roadway, but if it is added to the creative operation, it is enthusiasm. In combination with the vestibular hydraulic sluicing and hydraulic drainage, the use of excess water to be vented, and the discharge of sediment, the sand concentration can be greatly increased to improve the efficiency of sediment removal.

7. Equipment cost savings can save the construction cost of platform ship equipment and the difficulty of construction such as towing and anchoring.

8. This creation - after installation, it can be on standby 24 hours a day, with high maneuverability for continuous operation, no need for platform ship equipment mobilization, recovery time-consuming, and high-risk work group of water surface and underwater professional work.

9. It can cooperate with the local demand, centering on the spillway, spillway and sand discharge tunnel, and presenting a three-dimensional streamlined fluid zone in the reservoir flood discharge, which can be sprayed on the underwater silt surface. The flow can be scoured and silted, and the vertical anchor seat and the floating table buoy can be automatically lifted and lowered with the water level to cooperate with the working platform, and the hanging device can be synchronously operated by long-distance fixed-point positioning, etc., and can also be artificially pumped and transported. The vestibule method of the mud injection facility expands the drainage area and sediment discharge efficiency of the overflow weir, spillway, drainage channel and sedimentation channel.

10. This creation has eliminated all the shortcomings of the previous surface floating platform, ship type mud dredger and deep water diving operation device and improved it.

11. This creation has the application of Article 23 of the Management Measures for the Use of Reservoir Water Storage Range. It can be installed at any time without any time-consuming environmental assessment.

Based on the above, the reservoir overflow weir, spillway, sediment discharge tunnel and the fixed submersible water jet jet silt disturbing device are used to strengthen the overflow weir, spillway and sediment discharge tunnel. The people who are engaged in water drainage are equipped with mechanical sand-passing facilities. When the traditional existing reservoirs are flooded by natural floods or manually operated gates, they simply discharge water and discharge floods or discharge flood discharge and discharge operations in the sand discharge tunnels. It is only the passive and passive thinking of natural drainage and sand discharge, which is changed to increase the strong positive idea of mechanical and hydraulic assistance for scouring and silting, and to improve the efficiency of water drainage. Concrete hydraulic structures such as spillway flood discharge, sediment discharge tunnels, etc. are installed at appropriate locations under the water surface. Taiwan, a high-pressure water jet formed by a large-scale high-pressure and high-flow submersible high-pressure water pump (sand-resistant wear-resistant reverse installation) or a high-pressure water jet is used to disturb the overflow weir, spillway, and sediment discharge tunnel. The vestibular silt body is supplemented by a vortex mixer to accelerate the smashing of the smashing, and the sand is instantaneously discharged by the action of hydraulic gravity, etc., and the pressure can be extended in the three-dimensional streamlined flow zone when the reservoir overflows the flood. The water pipe generates jet flow, expands the overflow raft, spillway, and the vestibule sand discharge area of the sand discharge flood control tunnel. No matter the water level rise and fall of the reservoir, it is not affected by the typhoon and rain weather environment, and can be immediately matched with the dredging and sediment discharge operation according to the instructions of the reservoir management unit. It will expand the effect of sand discharge, gain efficiency in sand discharge, save time, grasp the time and space of flood discharge and sand discharge, efficiency cost, operation cost, save energy and utilize the function of water resources for dredging and draining, and the goal of safe, convenient and efficient operation. Its practical effect is undoubted, especially for those who are used in overflow weirs, flood discharge and sand discharge tunnels. However, this creation has never been publicized in the city or has been seen in other publications, and it has long been eagerly awaited by the national reservoirs. It is necessary to seek the normal operation of the reservoir, activate and update the necessary facilities for sustainable operation, and the provisions of the Patent Law.提出 Submit a patent application according to law.
