Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and specifically to a method for constructing a water conservancy project canal. Background Art

[0002] A water conservancy project refers to a project built to eliminate water disasters and develop and utilize water resources. A water conservancy project is used to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. In water conservancy projects, the common one is to build canals to improve people's living environment and water use problems.

[0003] However, in the prior art, when building canals, generally methods such as advance siltation and cutoff are adopted for construction, and water is introduced after the whole canal is completed. But this construction method, because the water flow is silted and cut off at a certain place, the water will accumulate more and more. Therefore, when building the canal, it is also necessary to reinforce the river embankment where the water accumulates, etc. This not only makes the overall construction period longer, but also the cost is relatively high. In view of this, it is very necessary to design a method for constructing a water conservancy project canal to solve this problem. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for constructing a water conservancy project canal, which solves the problems in the prior art that when building a canal, generally methods such as advance siltation and cutoff are adopted for construction, and water is introduced after the whole canal is completed. But this construction method, because the water flow is silted and cut off at a certain place, the water will accumulate more and more. Therefore, when building the canal, it is also necessary to reinforce the river embankment where the water accumulates, etc. This not only makes the overall construction period longer, but also the cost is relatively high.

Detailed Description of the Invention

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 , the present invention provides a technical solution: a method for building a water conservancy project canal, including the following steps:

[0024] S1. Adopt directional blasting technology to simultaneously blast and build two parallel channels according to the designed canal route, depth and width. One of them is the main channel, and the other is the secondary channel. The water level of the secondary channel is higher than that of the main channel, and it is built from low altitude to high altitude;

[0025] S2. Conduct anti-seepage and anti-water-permeability design at the bottom and both sides of each section of the channel;

[0026] S3. Install gate devices at both ends of each section of the channel to prevent water from flowing into the low-altitude channel. Set 2-4 retractable semi-circular anti-yaw and upward-promoting water-blocking gates similar to the hull in the middle of each section of the channel. Roller is set on the water-blocking gate to prevent scratching the hull, and there is a retractable water-blocking plate and roller below to prevent scratching the bottom of the ship;

[0027] S4. Install windmill pumps, water diversion pumps, and thrust pumps between the main and secondary channels, and use wind energy, solar energy, and off-peak electric energy to convert into the kinetic energy of pumping water, pumping the water in the lower main river into the main river above the ship lock to ensure the water consumption for ships to pass throughout the year. The excess water can flow downward, and the insufficient part can be pumped back;

[0028] S5. After building two parallel channels, connect the original channel with the newly built main channel to achieve water connection;

[0029] S6. Build an electric power system on both sides of the canal to supply power to electric ships, etc.;

[0030] S7. Water users are built on both sides of the river channel, and reservoirs with a water storage capacity for 1-2 years of water consumption are constructed. During the flood season every year, the reservoirs are replenished with water. When the water volume is insufficient, seawater is pumped into the river. The fresh water is in the upper and middle reaches, and the seawater is in the lower and middle reaches. The fresh water and seawater are made to flow against each other to ensure the canal is navigable throughout the year.

[0031] It should be noted that the main river channel functions for shipping, flood drainage, drought resistance, water supply and energy storage. The secondary river channel functions to convert the kinetic energy of pumping water through windmill pumps, guide water pumps, etc., and pump the water in the lower main river channel into the river channel above the sluice gate. At the same time, the power system can use wind energy, solar energy, low-valley electric energy, etc. The secondary river channel can be designed as pipelines, branch rivers, reservoirs, etc., as long as it can ensure the balance of the water levels in the main river channels above and below the sluice gate. In this way, water is supplied from below the sluice gate to above the sluice gate, and reverse water flow can be achieved through artificial mechanical structures. The secondary river channel can be designed as a high-speed channel for small fast boats and a tourist sightseeing channel for small slow boats. The river channel can be used for freight and tourism.

[0032] The river channel runs east-west with a slope and has ship ladders. When the sluice gate device is closed, the water flows upstream, and when the sluice gate device is opened, the water flows downstream. There is only upstream and downstream flow near the sluice gate device, and the risk is controllable. When a ship passes through the sluice gate device, the water above will flow through the sluice gate to the lower part. When the water volume is equal to or less than the fuel consumption of the ship traveling 500 meters, we use wind-powered pumps, electric pumps, etc. to pump the flowing water volume back above the sluice gate, so that the water can be recycled repeatedly, making one part of water equivalent to ten parts, 600 = 6000, and the cost is controllable.

[0033] In this embodiment, it is further set that the sluice gate device includes a canal foundation 1. A pair of vertical rods 2 are erected on the top of the canal foundation 1. The top of the vertical rod 2 is hinged with a pressure rod 3. One end of the pressure rod 3 is equipped with a mobile locomotive 4, and a first stone block 15 is connected below the mobile locomotive 4. The other end of the pressure rod 3 is connected with a strap 5. The bottom end of the strap 5 is connected with a second stone block 6. An empty box 7 is installed at the bottom end of the second stone block 6. A pair of water pools 8 are processed in the top wall of the canal foundation 1, and the empty box 7 is located in the water pools 8. A first gate plate A2 9 and a second gate plate B2 10 are respectively arranged on the inner sides of the pair of water pools 8, and a third gate plate A1 11 and a fourth gate plate B1 12 are respectively installed on the first gate plate A2 9 and the second gate plate B2 10. The third gate plate A1 11 and the fourth gate plate B1 12 can be inserted into the two side walls.

[0034] The set sluice gate device can prevent backflow, and ships can pass through unobstructed. Preventing backflow is to ensure the canal water level, guarantee the water consumption for ships to pass through throughout the year. The excess water can flow downstream, and the insufficient part is pumped back by the water pump, ensuring smooth passage in water-scarce areas.

[0035] In this embodiment, it is further provided that the two keels of the first gate plate A2 9 and the second gate plate B2 10 are movably connected to the third gate plate A1 11, the fourth gate plate B1 12 and the two side walls.

[0036] When the ship hits the keel on the gate device, the gate device automatically opens, allowing the ship to pass through unobstructed. The gate device remains unharmed, and the hull remains unharmed. After passing through, the gate device automatically closes. To save the space occupied by the gate device, it can be made into a foldable form, folding when opening and unfolding when closing.

[0037] In this embodiment, it is further provided that a number of rollers 14 are arranged on the inner sides of the first gate plate A2 9 and the second gate plate B2 10.

[0038] In this embodiment, it is further provided that water passing ramps 13 communicating with the water pool 8 are machined inside both the third gate plate A1 11 and the fourth gate plate B1 12.

[0039] It should be noted that the standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The models of the electrical structure equipment involved can be selected according to the needs of the user, and only need to meet the usage requirements of this application. In addition, the circuit connection adopts the conventional connection method in the prior art. The control of electrical equipment, current detection, position feedback, prediction voltage synchronization, and parameter adjustment are all prior art and will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0040] Through those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0041] Embodiment: When this device needs to be used, directional blasting technology can be adopted. According to the designed canal route, depth and width, two parallel channels can be built by blasting simultaneously. One of them is the main channel, and the other is the secondary channel. The water level of the secondary channel is higher than that of the main channel and is built from low altitude to high altitude. Anti-seepage and anti-water-permeation designs are carried out at the bottom and both sides of each section of the channel. Gate devices are installed at both ends of each section of the channel to prevent water from flowing into the low-altitude channel. 2-4 retractable semi-circular anti-yaw and upward-promoting water-blocking gates similar to the hull are arranged in the middle of each section of the channel. Roller wheels are installed on the water-blocking gates to prevent scratching of the hull, and retractable water-blocking plates and roller wheels are arranged below to prevent scratching of the bottom of the ship. Windmill pumps, water diversion pumps, and thrust pumps are arranged between the main and secondary channels to convert the kinetic energy of pumping water using wind energy, solar energy, and low-valley electric energy, pumping the water in the lower main river into the main river above the ship lock to ensure the water consumption for ships to pass throughout the year. The excess water can flow downward, and the insufficient part can be pumped back. After building two parallel channels, the original channel is connected to the newly built main channel to achieve water connection. An electric power system is built on both sides of the canal to supply power to electric ships, etc. Water-using units are built on both sides of the channel, and a reservoir with a water volume for 1-2 years of use is built. The reservoir is replenished with water during the flood season every year. When the water volume is insufficient, seawater is pumped into the river, with fresh water in the upper and middle reaches and seawater in the lower and middle reaches, and the fresh water and seawater are made to flow against each other to ensure the canal is navigable throughout the year;

[0042] When using the gate device, the movement of the mobile locomotive 4 on the pressure bar 3 can be controlled manually or automatically, so that the pressure bar 3 cooperates with the first stone 15, the vertical rod 2, the binding strap 5, etc. to drive the second stone 6 to rise. When the pressure of the second stone 6 on the lower empty box 7 decreases, the empty box 7 will rise accordingly. At this time, the water in the first gate plate A2 9 and the second gate plate B2 10 will flow into the water pool 8 through the water passing ramp 13. At the same time, under the pressure of the water flow inside the canal foundation 1, the third gate plate A1 11 and the fourth gate plate B1 12 will drive the first gate plate A2 9 and the second gate plate B2 10 to move and insert into the slots of the canal foundation 1, so as to open the first gate A2 9 and the second gate B2 10. Conversely, it can be closed, so that ships can pass unobstructed, and at the same time, it can also prevent water from flowing into the low-altitude channel;

[0043] Function of the gate device: Keep the water stagnant in the current channel. When a ship passes through the gate device, the gate opens, and after the ship passes, the gate closes. At the same time, rollers can be designed at the gate device to prevent scratching of the hull and ensure unobstructed passage of the hull.
