Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a vertical inclined flood control irrigation dam and a construction method thereof. Background Art

[0002] Using rivers to irrigate paddy fields can give full play to the advantages of water conservancy. There are large areas of farmland on both sides of the rivers in the Northeast region. Every few kilometers above and below each river, a dam needs to be built to irrigate the farmland. However, the existing dams cannot be used effectively for a long time. Some dams have to be built repeatedly in spring, summer and autumn, and the construction of dams has occupied a large amount of funds in the village.

[0003] Problems with existing traditionally constructed dams:

[0004] 1. The dam length, width and depth of the foundation platform are not enough. The platform built with rubble, mortar and cement is not solid, the solidification is not strong and there are holes.

[0005] Second, the stone retaining wall built on the dam foundation platform does not rise from the root of the foundation. An isolation layer is formed between the foundation platform surface and the stone retaining wall, which cannot withstand the impact of a flood.

[0006] 3. Because the height difference between the stone retaining wall and the river banks on both sides is very small, when it rains continuously in July and August, the water levels of rivers and streams rise sharply. The flood washes away the filling materials on the upper side of the stone vertical retaining wall. Because the vertical stone retaining wall cannot tilt, it cannot resist the erosion of the flood and causes the dam to be destroyed.

[0007] Fourth, because the stone retaining wall is soaked in half water and half leaking all year round, it will crack when it encounters frost damage in winter, causing the dam to be destroyed when floods come.

[0008] Therefore, how to provide a vertical inclined flood control irrigation dam and a construction method thereof is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0009] In view of this, the present invention provides a vertical inclined flood control irrigation dam and a construction method thereof, which can intercept water for irrigation when the water flow is small, and ensure the smooth passage of flood when a flood occurs, thereby reducing the impact of the flood on the dam body.

[0010] In order to achieve the above object, the present invention adopts the following technical solution: a vertical inclined flood control irrigation dam, comprising:

[0011] A river channel base, with dam walls fixed on both sides of the river channel base, a water-passing river channel formed between the river channel base and the dam walls on both sides, and a plurality of positioning hooks linearly arranged on the river channel base;

[0012] Anchoring platforms, the anchoring platforms have two groups and are located on two outer sides of the water-passing channel, and a plurality of anchoring pieces are fixed on the anchoring platforms;

[0013] A movable water baffle, the movable water baffle is flipped and connected to the water channel, a water inlet is opened on the dam wall upstream of the movable water baffle, a water diversion channel connected to farmland is arranged on the outside of the dam wall, and the water inlet diverts the water flow in the water channel into the water diversion channel;

[0014] A water baffle flipping pull wire, wherein the water baffle flipping pull wires are multiple and are connected to the back water surface of the movable water baffle at intervals up and down, the water baffle flipping pull wires are connected to the anchors at the corresponding ends after passing through the threading tubes on the dam wall, a tensioner is connected between the water baffle flipping pull wires and the anchors, and the water baffle flipping pull wires on the bottom side of the movable water baffle are connected to the positioning hook and are used to limit the flipping position of the movable water baffle.

[0015] The beneficial effects of the present invention are as follows: a river channel base is constructed in the river channel, which is the basic platform of the dam body. The anchoring platform is used to provide an anchoring foundation for controlling the flipping of the movable water baffle. The looseness of the pull line of the water baffle flipping allows the movable water baffle to have different flipping angles, thereby achieving different functions of water blocking and water passing. Specifically, the flipping position of the movable water baffle needs to be achieved by the positioning hook on the river channel base, thereby ensuring the stable flipping of the movable water baffle and not moving due to the impact of the water flow. The present invention is adjusted and used according to the amount of water used. When the flow of river water is small, the movable water baffle is raised. When a large flood strikes, the movable water baffle should be released in time to be level with the river channel base to allow the large flood to pass smoothly. When the flood recedes, the water baffle is raised to continue to irrigate the fields for the people.

[0016] Preferably, the river channel base and the dam wall are cast in one piece, and a reef buffer zone for buffering flood flow rate is provided on the river channel base downstream of the movable water retaining plate.

[0017] The resulting technical effect is that the riverbed and the dam wall are cast in one piece, the structure is highly stable and not easily damaged, and the reef buffer zone can reduce the flow rate of the flood when it comes, thereby reducing the impact of the flood on the dam body.

[0018] Preferably, the positioning hooks are provided in multiple groups and fixed at intervals on the river channel base, and the positioning hooks are chicken claw hooks.

[0019] The resulting technical effect is: the positioning hook is used to locate the position of the movable water baffle, thereby ensuring its reliable working process, and the chicken claw hook has multiple claws, thereby increasing the limiting points of the bottom side water baffle flipping pull line.

[0020] Preferably, there are multiple threading tubes on the dam wall and they are arranged at intervals up and down, the number of the threading tubes on the dam wall corresponds to the number of water retaining plate flip pull lines, one end of the threading tube is flared, the flared end of the threading tube is close to one side of the water channel, the flared end on the threading tube is an asymmetric oblique trumpet mouth, the long oblique side of the oblique trumpet mouth is close to the downstream of the water flow, and a rubber water plug is fixed near the oblique trumpet mouth of the water retaining plate flip pull line. When the water retaining plate flip pull line is tightened, the rubber water plug seals the threading tube and prevents the water source inside the water channel from leaking out.

[0021] The technical effect produced thereby is: the threading tube provides a wall-penetrating foundation for the water retaining plate flipping pull wire, thereby establishing a connection relationship between the water retaining plate flipping pull wire and the anchor on the anchor platform; in addition, one end of the threading tube is designed with an oblique bell-mouth, which is convenient for the oil wire rope to slip and prevents the rubber-coated outer skin of the oil wire rope from rubbing when the tensioner is used to tighten the wire, thereby affecting the service life of the oil wire rope; due to the oblique bell-mouth, when vertical oblique water blocking is performed and rapid water overflows the dam, it can also play a role in buffering the oil wire rope and the water retaining plate; it should be noted that the water blocking of the present invention is not water blocking in the full sense, but rather raises the upstream water level to a certain extent, thereby realizing water diversion to farmland.

[0022] Preferably, the anchoring platform is a concrete platform, the anchor is a wire fixing bottom ring, the water baffle flipping wire is an oil wire rope, the two ends of the oil wire rope are forked to form a ring, the hooks at both ends of the tensioner are respectively connected to the ring and the wire fixing bottom ring on the corresponding side, and an operating room is provided on the anchoring platform, and the anchor and tensioner are located in the operating room.

[0023] The resulting technical effect is: the anchor is a bottom ring for fixing the pull wire, the purpose of which is to provide a basis for pulling the water baffle flipping pull wire. Specifically, a tensioner is used to adjust the tightness of the entire water baffle flipping pull wire. It should be noted that since there are multiple water baffle flipping pull wires, the tightness of different water baffle flipping pull wires needs to be adjusted according to usage. The tensioner can be a manual tensioner or an electric tensioner, which can be selected according to needs. The operation room can meet the needs of multiple operations, avoiding water immersion of anchors and tensioning equipment, and the operation room also provides installation space for subsequent electronic equipment.

[0024] Preferably, both ends of the movable water baffle extend to the dam wall on the corresponding side, and the movable water baffle includes a water-facing surface splint, a rubber lining and a water-receiving surface splint, and the water-facing surface splint, the rubber lining and the water-receiving surface splint are fixedly connected by splint screws, and a plurality of hanging line noses are arranged on the water-receiving surface splint, and the hanging line noses on the plurality of water-receiving surface splints are arranged in rows, and the water baffle flipping pull line is passed through the hanging line noses in the corresponding row.

[0025] The resulting technical effect is that even if the movable water baffle is raised, it is impossible to avoid complete water blocking. A small amount of water will leak from the edge of the movable water baffle. This is an acceptable situation. Of course, the leakage amount must be smaller than the upstream water flow, thereby ensuring that the upstream water level rises and achieving the purpose of water diversion. Flow-stabilizing blocks are set at the corners of the downstream position where the water baffle is flipped.

[0026] The present invention also discloses a method for constructing a vertical inclined flood control irrigation dam, which comprises the following steps:

[0027] Step 1: Site selection: Choose a shallow river section above the irrigation field with high natural terrain;

[0028] Step 2: Foundation construction: dig a casting trough for the riverbed in the river channel, and ensure that the length of the riverbed corresponding to the water retaining surface is greater than the width of the river channel. The depth of the riverbed is determined according to different terrain and water storage on the dam;

[0029] Step 3: The dam body is formed by pouring the dam wall on both sides of the riverbed, opening a water inlet on the dam wall, setting anchoring platforms on both sides of the riverbed, and pre-embedding multiple anchors on the anchoring platforms;

[0030] Step 4: Installation of the movable water baffle, the water baffle flipping pull line is passed through the hanging line nose on the back surface of the movable water baffle, the water baffle flipping pull line on the bottom side is connected to multiple positioning hooks on the water channel and defines the flipping axis of the movable water baffle, and multiple water baffle flipping pull lines on the upper side are passed through the threading tube on the dam wall and connected to the anchor, and the tensioner between the water baffle flipping pull line and the anchor is adjusted to adjust the flipping angle of the movable water baffle;

[0031] Step 5: Use movable water retaining plates. When the water flow in the river is small, pull up the movable water retaining plates to block the water flow, raise the water level upstream, and divert irrigation water to the farmland through the water inlet. When the water flow in the river is large and a flood occurs, lay the movable water retaining plates flat and clear the water flow. At this time, use the gate at the water inlet to close it, and the flood can pass safely.

[0032] The beneficial effects of the present invention are: suitable site selection ensures that the irrigation field can be irrigated, and the present invention can adjust the use according to the usage and river water conditions by flipping and adjusting the movable water retaining plate, thereby ensuring the irrigation effect and preventing the risk of dam collapse.

[0033] Preferably, in step one, the terrain on both sides of the river channel is flat, the river section is straight, the drainage is smooth, and the discharged water will not impact the river banks on both sides.

[0034] The resulting technical effect is that the terrain on both sides of the river is flat and the river section is straight, with the aim of ensuring that the water flow will not impact the river banks on both sides during drainage.

[0035] Preferably, in step three, a reinforcing rib is fixed between the anchor platform and the dam wall, the reinforcing rib is inclined toward the upstream side of the water flow, the anchors on the anchor platform are staggered, and the number of the anchors on each end of the anchor platform corresponds to the number of flip tension lines of the water retaining plate.

[0036] The resulting technical effect is: the anchor platform and the dam wall are connected by reinforcing ribs, which are arranged obliquely to form an integral structure with strong stability, which can improve the substrate's ability to resist water flow impact, and the staggered distribution of anchors can avoid concentrated force and make the force more uniform. Both ends of each water retaining plate flipping cable are connected to the anchors on the anchor platform through a tensioner.

[0037] Preferably, in step 4, a pipe hole adapted to the shape of a threading pipe is pre-opened on the dam wall, the threading pipe is arranged close to the upstream of the water head, and the threading pipes on the dam wall are arranged obliquely and staggered from top to bottom.

[0038] The resulting technical effect is: the purpose of arranging the threading pipe close to the upstream of the water head is to adjust the installation position of the water retaining plate, so that the force point of the water retaining plate is advanced, thereby reducing the impact of the water body on the structure; the threading pipe is arranged obliquely from top to bottom so that the water retaining plate is inclined in the water blocking state, reducing the impact load of the water body.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0049] See the attached Figures 1 to 8 According to an embodiment of the present invention, a vertical inclined flood control irrigation dam comprises:

[0050] A river channel base 1, dam walls 2 are fixed on both sides of the river channel base 1, a water channel is formed between the river channel base 1 and the dam walls 2 on both sides, and a plurality of positioning hooks 3 are linearly arranged at intervals on the river channel base 1. It can be understood that the plurality of positioning hooks arranged at intervals are on a straight line;

[0051] Anchoring platforms 4, there are two groups of anchoring platforms 4 and they are located on two outer sides of the water channel, and a plurality of anchoring pieces 5 are fixed on the anchoring platforms 4;

[0052] The movable water retaining plate 6 is turned over and connected to the water channel. The dam wall 2 is provided with a water inlet 7 upstream of the movable water retaining plate 6. The outer side of the dam wall 2 is provided with a water diversion channel connected to the farmland. The water inlet 7 diverts the water flow in the water channel to the water diversion channel to realize the irrigation of the farmland.

[0053] The water baffle flip pull wire 8 has multiple water baffle flip pull wires 8 and is arranged at intervals up and down on the back water surface of the movable water baffle 6. The water baffle flip pull wire 8 passes through the threading tube 11 on the dam wall 2 and is connected to the anchor 5 at the corresponding end. A tensioner 9 is connected between the water baffle flip pull wire 8 and the anchor 5. The tensioner has a variety of options, which can be a manual tensioner or a manual chain hoist. Where there is a power supply, it can be an electric tensioner, a battery-driven tensioner, a hydraulic tensioner, a gear-engaged transmission shaft tensioner. It can also be an intelligent remote control, remote operation tensioning, etc. The arrangement is selected according to actual needs. The water baffle flip pull wire at the bottom edge of the movable water baffle 6 is connected to the positioning hook 3 and is used to limit the flipping position of the movable water baffle 6 to avoid displacement of the movable water baffle.

[0054] In other embodiments, the riverbed 1 and the dam wall 2 are cast in one piece, and a reef buffer zone 10 for buffering the flow rate of floods is provided on the riverbed 1 downstream of the movable water retaining plate 6 .

[0055] In some other embodiments, there are multiple groups of positioning hooks 3 fixed on the riverbed 1 at intervals of 1 m. The positioning hooks 3 are chicken claw hooks. The multiple claws of the chicken claw hooks increase the connection points, making the flipping of the movable water retaining plate more stable. The specific structure shall be subject to the actual product.

[0056] In some other specific embodiments, a plurality of threading tubes 11 are arranged on the dam wall 2 from top to bottom, and one end of the threading tube 11 is expanded, and the expanded end of the threading tube 11 is close to one side of the water channel. The expanded end on the threading tube 11 is an asymmetric oblique trumpet mouth 111, and the long oblique side of the oblique trumpet mouth 11 is close to the downstream of the water flow. A rubber water plug is fixed near the oblique trumpet mouth of the water retaining plate flipping pull wire 8. When in the upright oblique state and the water retaining plate flipping pull wire 8 is tightened, the rubber water plug moves and blocks the threading tube 11, thereby preventing the water source inside the water channel from entering the operating room. The threading tube provides a wall penetration foundation for the water retaining plate flipping pull wire. The threading tube 11 at the top is close to the upstream of the water head, which ensures the inclined state of the water retaining plate when it is raised, and also reduces the impact of the water body on the overall structure. When pulling the wire, due to the setting of the oblique trumpet mouth of the threading tube, the degree of wear of the rubber coating on the outer skin of the oil wire rope can be reduced.

[0057] In other embodiments, the anchoring platform 4 is a concrete platform, the anchor 5 is a wire fixing bottom ring, the water retaining plate flipping wire 8 is an oil wire rope, the oil wire rope has a good anti-rust effect and is not easy to break, the two ends of the oil wire rope are forked to form a ring, and the hooks at both ends of the tensioner 9 are respectively connected to the rings and the wire fixing bottom ring on the corresponding side. An operating room is provided on the anchoring platform 4, and the anchor 5 and the tensioner 9 are located in the operating room. Specifically, the operating room is composed of a water-resistant board wall enclosure and a rainproof shed, which is waterproof and rainproof to ensure that the tensioning equipment and anchors are not soaked in water. The operating room has emergency operation space for less than 4 people to ensure the installation of an automatic intelligent remote control equipment platform after modification.

[0058] In some other specific embodiments, both ends of the movable water baffle 6 extend to the dam wall 2 on the corresponding side. The movable water baffle 6 includes a water-facing surface plywood 61, a rubber lining 62 and a water-receiving surface plywood 63. The water-facing surface plywood 61, the rubber lining 62 and the water-receiving surface plywood 63 are fixedly connected by plywood screws. The plywood screws should be made of stainless steel and treated with oil seal wax to prevent rust caused by long-term immersion in water. A plurality of hanging line noses 12 are arranged on the water-receiving surface plywood, at least three groups, one group on the top edge, one group in the middle, and one group on the bottom edge. The hanging line noses on the plurality of water-receiving surface plywood are arranged in rows. The water baffle flipping pull wire 8 is passed through the hanging line nose 12 of the corresponding row, and the flipping state of the movable water baffle is controlled by the tightness of the water baffle flipping pull wire.

[0059] It should be noted that there are actually many implementation methods for the movable water baffle, and it is not limited to one or two situations shown in the drawings. It only needs to meet the need to raise the water level in the upright and inclined state, and no excessive requirements are made here.

[0060] The present invention also discloses a method for constructing a vertical inclined flood control irrigation dam, which comprises the following steps:

[0061] Step 1: Site selection: Choose a shallow river section above the irrigation field with high natural terrain;

[0062] Step 2: Build the foundation. Dig a casting groove for the riverbed in the river, and ensure that the length of the riverbed corresponding to the water retaining surface is greater than the width of the river. The depth of the riverbed is determined according to the different terrain and the water storage capacity on the dam. Taking a 50-meter river width as an example, the foundation is 80 meters, the dam foundation width is 10-15 meters, and the dam foundation depth is determined according to the different terrain and the water storage capacity on the dam. It is subject to measurement and is generally 1.5-2 meters. 15 meters at each end of the dam foundation is the anchorage pit for burying the cable, which should be appropriately deepened, and the cable pit should be tilted upward to prevent pressure from being generated when the dam is filled with water;

[0063] Step 3: The dam body is formed. The dam wall is cast on both sides of the riverbed, and a water inlet is opened on the dam wall. Anchor platforms are set on both sides of the riverbed, and multiple anchors are embedded on the anchor platforms; one anchor is set every 2.5 meters, and the number of anchors at each end of the dam head is set according to the number of tension wires;

[0064] The positioning hooks on the riverbed are calculated based on the length of the dam foundation, with one ring hook pointing upward for every meter. The specific implementation is subject to the actual layout and use;

[0065] Step 4: Installation of the movable water baffle, the water baffle flipping pull line is passed through the hanging line nose on the back surface of the movable water baffle, the water baffle flipping pull line on the bottom side is connected to multiple positioning hooks on the water channel and defines the flipping axis of the movable water baffle, and multiple water baffle flipping pull lines on the upper side are passed through the threading tube on the dam wall and connected to the anchor, and the tensioner between the water baffle flipping pull line and the anchor is adjusted to adjust the flipping angle of the movable water baffle;

[0066] The length and height of the movable water retaining plate should be determined according to the length of the dam. The height standard is the horizontal plane of the riverbed platform, which is level with the bottom of the water inlet channel. The water retaining plate turning pull line uses oil wire rope, and its specifications meet the requirements of dam foundation length, thickness and tensile strength.

[0067] Step 5: Use movable water retaining plates. When the water flow in the river is small, pull up the movable water retaining plates to block the water flow, raise the water level upstream, and divert irrigation water to the farmland through the water inlet. When the water flow in the river is large and a flood occurs, lay the movable water retaining plates flat and clear the water flow. At this time, use the gate at the water inlet to close it, and the flood can pass safely.

[0068] In step one, the terrain on both sides of the river channel is flat, the river section is straight, the drainage is smooth, and the discharged water will not impact the river banks on both sides.

[0069] In step three, a reinforcing rib 13 is fixed between the anchor platform 4 and the dam wall 2, and the anchors on the anchor platform 4 are staggered and distributed, and the number of the anchors on each end of the anchor platform corresponds to the number of the water retaining plate flip pull lines.

[0070] In step 4, the threading pipe 11 is arranged close to the upstream of the water head, and the threading pipes on the dam wall are arranged obliquely and staggered from the top to the bottom.

[0071] An operation room can also be set up at the anchoring platforms at both ends, and various special operation tools are kept in the room.

[0072] Installation process:

[0073] When installing the movable water retaining plate, the first oil wire rope under the movable water retaining plate should be passed through the dam wall through the threading tube at both ends. Then connect the oil wire rope head rings on both sides to the tensioner hook, and then connect the other end hook of the tensioner to the bottom rings of the two ends of the pull line, and then use the manual tensioner to lightly and simply fix the first oil wire rope as the first axis, and then use the steel fiber to pull the first axis on the platform chicken claw bottom ring hook, and then tighten and fix the first axis. Then the second and third oil wire ropes are connected to the hanging line nose and also passed through the dam wall to connect to the tensioner, and the other end hook of the tensioner is connected and fixed to the bottom ring of the pull line.

[0074] After all the oil wire ropes are put through, full-time personnel are trained to conduct drills and debugging, and to carry out maintenance and repair. The water is adjusted according to the amount of water used. When the river flow is small, the movable water baffle is raised. When a large flood hits, the movable water baffle is released in time to be level with the riverbed platform to allow the large flood to pass smoothly. When the flood recedes, the water baffle is raised to continue irrigating the fields for the people.

[0075] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0076] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.

The depth of the riverbed is determined according to different terrain and water storage on the dam; Step 3: The dam body is formed by pouring the dam wall on both sides of the riverbed, opening a water inlet on the dam wall, setting anchoring platforms on both sides of the riverbed, and pre-embedding multiple anchors on the anchoring platforms; Step 4: Installation of the movable water baffle, the water baffle flipping pull line is passed through the hanging line nose on the back surface of the movable water baffle, the water baffle flipping pull line on the bottom side is connected to multiple positioning hooks on the water channel and defines the flipping axis of the movable water baffle, and multiple water baffle flipping pull lines on the upper side are passed through the threading tube on the dam wall and connected to the anchor, and the tensioner between the water baffle flipping pull line and the anchor is adjusted to adjust the flipping angle of the movable water baffle; Step 5: Use movable water retaining plates. When the water flow in the river is small, pull up the movable water retaining plates to block the water flow, raise the water level upstream, and divert irrigation water to the farmland through the water inlet. When the water flow in the river is large and a flood occurs, lay the movable water retaining plates flat and clear the water flow. At this time, use the gate at the water inlet to close it, and the flood can pass safely.

8. The method for constructing a vertical inclined flood control irrigation dam according to claim 7, characterized in that: In the step 1, the terrain on both sides of the river channel is flat, the river section is straight, the drainage is smooth, and the discharged water will not impact the river banks on both sides.

9. The method for constructing a vertical inclined flood control irrigation dam according to claim 7, characterized in that: In the step three, a reinforcing rib (13) is fixed between the anchor platform (4) and the dam wall (2), and the reinforcing rib (13) is inclined toward the upstream side of the water flow. The anchors on the anchor platform (4) are staggered and distributed, and the number of the anchors on each end of the anchor platform corresponds to the number of the water retaining plate flip tension lines.

10. The method for constructing a vertical inclined flood control irrigation dam according to claim 7, characterized in that: In the step 4, a pipe hole adapted to the shape of a threading pipe is pre-opened on the dam wall, and the threading pipe (11) is arranged close to the upstream of the water head. The threading pipes on the dam wall are arranged in a staggered manner from top to bottom.
