Description

Technical Field

[0001] The invention patent relates to the technical field of water retaining and drainage structures, specifically, to a single-channel water retaining and drainage structure that can be constructed quickly. Background Art

[0002] A culvert is a drainage channel, or water passage, built beneath the roadbed during highway construction to allow the highway to pass smoothly through a canal without obstructing traffic. This structure allows water to flow underneath the road, serving as a drainage channel across natural ravines and depressions. A gully is a channel formed by intermittent water flow on the surface. It is commonly found in hilly and mountainous areas with complex geological conditions and is the largest type of erosion gully.

[0003] When sudden floods occur, the water flow is large, and the water from culverts, gullies, and ditches collapses the slopes, etc., emergency rescue and repair of the collapsed parts are required to avoid large landslides or road collapses.

[0004] In existing technologies, emergency rescue operations require intercepting and diverting water from culverts and gullies to prevent it from eroding the slopes and allowing for emergency repairs to the collapsed areas. However, due to high water flow rates, time constraints, and limited space, there is currently no optimal water diversion structure for intercepting and diverting water from culverts.

[0005] Therefore, the present invention proposes a single-channel water-blocking and diversion structure that can be quickly constructed. When water is flowing, on the one hand, a water retaining dam can be quickly constructed and diversion can be carried out to prevent the water from continuing to scour the lower part and causing the landslide to expand, and on the other hand, construction opportunities can be created for the lower landslide. Summary of the Invention

[0007] The present invention is achieved by providing a single-channel water diversion structure that can be quickly constructed, comprising a headwater weir, an intermediate weir, a backwater weir, and a drainage pipe arranged in a waterway. The headwater weir, the intermediate weir, and the backwater weir are sequentially spaced along the flow direction of the water in the waterway.

The water inlet end extends into the incoming water area, the drainage pipe extends to the outside of the waterway, and the drainage end extends to the drainage area. Water in the incoming water area enters the drainage pipe from the water inlet end, is guided to the drainage area by the drainage pipe, and is discharged into the drainage area from the drainage end.

[0009] The water inlet end has a water inlet, and the water inlet is provided with a filter layer formed by weaving metal wire strips.

The tilt angles of the plurality of blades are different, and the plurality of blades surround a water inlet area that is larger at the front and smaller at the back.

[0011] When the water in the front water area flows toward the water inlet, the water drives the filter layer to rotate at the water inlet through the plurality of blades, so as to accelerate the water to pass through the filter layer and enter the water inlet.

[0012] Furthermore, the water-incoming dam is formed by stacking a plurality of water-incoming sand bags from top to bottom, and adjacent water-incoming sand bags are arranged in a transverse staggered manner along the height direction of the water-incoming dam.

[0015] Furthermore, the backwater dam is formed by stacking a plurality of backwater sand bags from top to bottom, and adjacent backwater sand bags are arranged in a transverse staggered manner along the height direction of the backwater dam.

[0016] Furthermore, the drainage pipe has a backwater built-in section embedded in the backwater dam. After the drainage pipe moves through the backwater dam, it extends outward in a direction deviating from the waterway, extending the drainage end into the drainage area.

[0017] Furthermore, the middle dam has a front end wall facing the upstream dam and a rear end wall facing the downstream dam, the front end wall is inclined backward away from the upstream dam, and the rear end wall is inclined forward away from the downstream dam; the upstream dam is inclined backward and rests on the middle dam, and the downstream dam is inclined forward and rests on the middle dam.

[0019] Furthermore, the rotating ring is connected to two symmetrically arranged elastic sheets, the outer ends of the elastic sheets movably abut against the rotating ring, the inner ends of the elastic sheets extend into the protruding space and are arranged obliquely toward the middle of the middle portion, and the outer ends of the elastic sheets form abutment ends abutting against the middle of the middle portion;

[0032] Reference Figure 1-5 The figure shows a preferred embodiment of the present invention.

[0033] The single-channel water interception and diversion structure can be constructed quickly and can be used in waterways, including culverts, tunnels and other waterways that require interception and diversion.

[0034] The single-channel water diversion structure that can be quickly constructed includes a water-incoming dam 100, an intermediate dam 200, a water-receiving dam 300 and a drainage pipe 400 arranged in the waterway. The water-incoming dam 100, the intermediate dam 200 and the water-receiving dam 300 are arranged in sequence along the flow direction of the water in the waterway. The waterway has a water-incoming area, a water-isolating area and a water-stopping area. The water-incoming area is formed in front of the water-incoming dam 100, the water-isolating area is formed between the water-incoming dam 100 and the water-receiving dam 300, the water-stopping area is formed behind the water-receiving dam 300, and the intermediate dam 200 is arranged in the water-isolating area.

[0035] Specifically, one or more drainage pipes 400 are designed according to the on-site long water flow conditions.

[0036] The drainage pipe 400 has an inlet end and a outlet end. The drainage pipe 400 passes through the incoming water dam 100, the middle dam 200 and the back water dam 300 in sequence. The inlet end extends to the incoming water area, the drainage pipe 400 extends to the outside of the waterway, and the outlet end extends to the drainage area. The water in the incoming water area enters the drainage pipe 400 from the inlet end, is led to the drainage area by the drainage pipe 400, and is discharged to the drainage area from the outlet end.

[0037] The incoming dam 100, the middle dam 200 and the backwater dam 300 can be used to intercept the water in the waterway, and the drainage pipe 400 can be used to divert the water in the incoming area to the drainage area instead of continuing to flow along the waterway, thereby preventing the water from eroding the slopes and making it easier for maintenance personnel to carry out emergency rescue work.

[0038] The water inlet end has a water inlet, which is provided with a filter layer 500 woven from metal wire strips. The outer periphery of the filter layer 500 is provided with a rotating ring 505, which is arranged around the circumference of the filter layer 500 and is rotatably connected to the outer periphery of the water inlet end.

[0039] The filter layer 500 protrudes away from the water inlet in a spherical shape, and the filter layer 500 surrounds a protruding space 507 arranged toward the water inlet; the rotating ring 505 extends outward to form a plurality of blades 600, and the plurality of blades 600 are arranged around the circumference of the rotating ring 505 at intervals; the inner ends of the blades 600 are docked on the rotating ring 505, and the outer ends of the blades 600 are arranged tilted forward away from the water inlet, and the inclination angles of the plurality of blades 600 are different, and the plurality of blades 600 surround a water inlet area that is larger in the front and smaller in the back.

[0040] When the water in the front water area flows toward the water inlet, the water drives the filter layer 500 to rotate at the water inlet through the multiple blades 600 to accelerate the water to pass through the filter layer 500 and enter the water inlet.

[0041] The inclination angles of the multiple blades 600 are different, which makes it easier for the multiple blades 600 to be subjected to uneven force, thereby forming a circumferential rotation, thereby driving the filter layer 500 to rotate, and the multiple blades 600 are surrounded to form a water inlet area, which makes it easier for the water in the water-facing area to flow to the water inlet area and quickly pass through the filter layer 500 into the water inlet for drainage.

[0042] The protruding filter layer 500 can be used to intercept impurities in the water body, preventing the impurities from entering the drainage pipe 400, causing blockage of the drainage pipe 400 or a decrease in the drainage speed, etc.; when the impurities are intercepted by the filter layer 500, as the filter layer 500 rotates, they will be thrown away from the filter layer 500 to avoid blockage of the filter layer 500, and the inclination angles of the multiple blades 600 are different. While driving the filter layer 500 to rotate, it can also drive the filter layer 500 to vibrate in multiple directions, making it easier for impurities to separate from the filter layer 500.

[0043] The plurality of blades 600 surround and form a water inlet area. As the blades 600 rotate, the water in the front water area can be guided to enter the water inlet area more quickly, thereby achieving a faster drainage effect.

[0044] The single-channel water interception and diversion structure provided above, which can be quickly constructed, utilizes the upstream dam, the middle dam 200 and the downstream dam 300 to form a whole, intercepts the water in the waterway, and utilizes the drainage pipe to divert the water in the upstream area to the drainage area, thereby achieving the effect of water interception and diversion, so as to facilitate maintenance personnel to carry out emergency rescue construction; secondly, by arranging a rotating filter layer 500, impurities can be intercepted, and the intercepted impurities can be quickly separated from the filter layer 500, and the water in the upstream area can be quickly drained to the water inlet area for rapid drainage.

[0045] In this embodiment, the water-incoming dam 100 is formed by stacking multiple water-incoming sandbags from top to bottom. Adjacent water-incoming sandbags are arranged transversely and staggered along the height of the water-incoming dam 100. Before the water-incoming sandbags are arranged, water-blocking boards can be inserted into the waterway to temporarily block the water. The water-incoming sandbags can then be quickly stacked to form the water-incoming dam 100.

[0046] The adjacent water-facing sand bags are arranged in a transverse staggered manner, so that the longitudinally adjacent or transversely adjacent water-facing sand bags can be firmly connected and have better integrity.

[0047] In this embodiment, the drainage pipe 400 has a water-facing built-in section 401 embedded in the water-facing dam 100, and the water inlet end of the drainage pipe 400 extends outside the water-facing dam 100 and is exposed in the water-facing area. In this way, it is easier for the water in the water-facing area to enter the drainage pipe 400.

[0048] The middle dam 200 is formed by filling the water barrier with quick-setting cement soil, and the drainage pipe 400 has a middle built-in section 402 embedded in the middle dam 200. During the construction of the water-facing dam 100, the construction of the middle dam 200 can be carried out simultaneously to ensure rapid construction.

[0049] In this embodiment, the backwater dam 300 is formed by stacking multiple backwater sand bags from top to bottom. Along the height direction of the backwater dam 300, adjacent backwater sand bags are arranged in a transverse staggered manner, which can ensure that the longitudinally adjacent or transversely adjacent backwater sand bags are firmly connected and have better integrity.

[0050] The drainage pipe 400 has a backwater built-in section 403 embedded in the backwater dam 300. After the drainage pipe 400 passes through the backwater dam 300, it extends outward in a direction deviating from the waterway and extends the drainage end to the drainage area.

[0051] The outer periphery of the backwater section 403 of the drainage pipe 400 can be provided with an elastic wrapping layer. This elastic wrapping layer surrounds the circumference of the backwater section 403 and is embedded in the backwater dam 300. It is subjected to the circumferential pressure of the backwater dam 300. However, the presence of the elastic wrapping layer allows the backwater section 403 to be movable within a set range of 360 degrees. When the water flow rate in the drainage pipe 400 is high, the backwater section 403 can swing within the set range, actively regulating the water flow and ensuring smoother water flow in the drainage pipe 400.

[0052] In this embodiment, the middle dam 200 has a front end wall facing the upstream dam 100 and a rear end wall facing the downstream dam 300. The front end wall is inclined backward away from the upstream dam 100, and the rear end wall is inclined forward away from the downstream dam 300. The upstream dam 100 is inclined backward and rests on the middle dam 200, and the downstream dam 300 is inclined forward and rests on the middle dam 200.

[0053] In this way, the upstream dam 100 and the downstream dam 300 are respectively inclined and leaned against the middle dam 200, so that the integrity is stronger, and the upstream dam 100 is more stable when subjected to the impact of the water body.

[0054] In this embodiment, the filter layer 500 includes a middle portion 501 and a ring-shaped outer portion 503. The outer portion 503 is arranged around the outer periphery of the middle portion 501. A ring-shaped elastic band 502 is provided between the outer periphery of the middle portion 501 and the inner periphery of the outer portion 503. The elastic band 502 elastically combines the middle portion 501 and the outer periphery into one; the middle portion 501 and the outer periphery are respectively arranged to protrude away from the water inlet, and the rotating ring 505 is provided on the outer periphery of the outer portion 503.

[0055] In this way, for the filter layer 500, the middle part 501 can move back and forth elastically relative to the outer part 503 as a whole. When subjected to the impact of water, the middle part 501 can move back and forth elastically and rotate synchronously with the outer part 503, so that impurities intercepted on the filter layer 500 can be quickly detached, thereby preventing the impurities from clogging the filter layer 500.

[0056] In this embodiment, two symmetrically arranged elastic sheets 506 are connected to the rotating ring 505. The outer ends of the elastic sheets 506 are movably abutted against the rotating ring 505. The inner ends of the elastic sheets 506 extend into the protruding space 507 and are inclined toward the middle of the middle part 501. The outer ends of the elastic sheets 506 form abutment ends 508 that abut against the middle of the middle part 501.

[0057] By arranging the elastic sheet 506 , when the middle portion 501 elastically reciprocates relative to the outer portion 503 , the elastic sheet 506 also elastically deforms accordingly, and the elastic force of the elastic sheet 506 can drive the rapid elastic reciprocating deformation of the middle portion 501 .

[0058] The abutting end 508 is spherical, and when the elastic sheet 506 undergoes elastic deformation, it facilitates displacement movement between the abutting end 508 and the middle portion 501. The elastic sheet 506 is provided with a plurality of through holes 5061, which penetrate the elastic sheet 506 along the flow direction of the water. This can reduce the impact force of the water on the elastic sheet 506. The elastic deformation of the elastic sheet 506 is driven by the reciprocating elastic deformation of the middle portion 501.

[0059] The elastic sheet 506 has an end face that is impacted by the water body, and the impacted end face is concave backward away from the water inlet to form multiple sections of concave grooves 5062. The multiple sections of concave grooves 5062 are arranged at intervals along the length direction of the elastic sheet 506. In this way, when the elastic sheet 506 is elastically deformed, it is convenient for the elastic sheet 506 to bend and deform elastically.

[0060] The middle part of the middle part 501 has a groove area 504 formed in the protruding space 507, the diameter of the groove area 504 is larger than the diameter of the abutting end 508, and the abutting end 508 is movably placed in the groove area 504; when the water in the front water area impacts the filter layer 500, the middle part 501 is elastically deformed back and forth relative to the outer part 503, and the elastic sheet 506 swings with the reciprocating elasticity.

[0061] When the elastic piece 506 is elastically deformed back and forth with the middle portion 501 , the abutting end 508 can be restricted in the recessed area, thereby preventing the abutting end 508 from deviating from a large position.

[0062] In this embodiment, there are longitudinal gaps and transverse gaps between adjacent water-facing sand bags. Geotextiles in a grid are provided in the longitudinal gaps and the transverse gaps. The geotextiles have multiple special-shaped holes 700. Multiple elastic strips 701 are provided in the special-shaped holes 700. The multiple elastic strips 701 are arranged in a vertical and horizontal cross pattern, and the multiple elastic strips 701 respectively abut against adjacent water-facing sand bags.

[0063] By arranging geotextiles, the longitudinal gaps and transverse gaps can be better filled, so that the entire water-facing dam 100 forms a closed whole, and multiple elastic strips 701 are formed in the special-shaped holes 700, which can abut against the water-facing sand bags. When misalignment occurs between the water-facing sand bags, the elastic strips 701 can be used to limit the friction between the water-facing sand bags, thereby avoiding large misalignment and movement.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
