Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to an anti-erosion device that is easy to lay. Background Technology

[0002] Constructing open channels is a common engineering project in water conservancy, primarily serving to temporarily guide water flow. Since open channels are generally temporary structures, considering various economic factors, using masonry or concrete structures to reinforce the slopes would be wasteful. In areas with large water volumes, due to water erosion and soft soil, directly excavating ditches as diversion channels often results in slopes that cannot withstand water erosion, easily leading to deformation and collapse. Traditionally, geotextile bags are used for direct stacking, but this method has low overall construction efficiency and is unsuitable for handling slopes, making dismantling later quite troublesome.

[0003] Chinese patent document CN 219315650 U describes an anti-scour flood discharge channel that requires the use of steel cages for installation, which is cumbersome and has high economic costs for temporary structures. Chinese patent document CN 218090726 U describes an anti-scour ditch structure for water flow engineering, which also has the above problems and has defects in use, requiring improvement.

[0006] In the preferred embodiment, the PE pipe is fixed to the slope with locking nails, and the two sides of the PE pipe are also provided with a first fixing head, which is connected by a connecting cable and a waterproof cloth.

[0007] In the preferred embodiment, the first fixing head includes a rod and a straight plate, with a locking hole through the straight plate. The rod is located inside the PE pipe. A second fixing head is provided on the upper side of the waterproof cloth, with a first through groove through the second fixing head. The two sides of the connecting cable pass through the locking hole and the first through groove, respectively.

[0008] In the preferred embodiment, two servo motors are symmetrically arranged on the top of the top seat, and a lock head is provided on the servo motor. A fixing plate is provided on the lower side of the waterproof cloth, and two second through slots are provided through the fixing plate. The lock head includes a mounting plate and an arc-shaped rod, and the arc-shaped rod passes through the two second through slots.

[0009] In a preferred embodiment, the top seat includes a top plate, and the bottom of the top plate is provided with a T-shaped plate. The T-shaped plate is connected by two parallel support plates and two movable frames.

[0010] In the preferred embodiment, two columns are arranged in parallel at the center of the top base, and two annular grooves are arranged in parallel on the columns. The columns are connected by a pull rope and a winding drum. The winding drum is set on the output shaft of the motor, and the motor is located on the river embankment.

[0011] In a preferred embodiment, the top two sides of the waterproof cloth are symmetrically provided with fixing straps, and the ends of the fixing straps are provided with locking rings.

Detailed Implementation

[0017] like Figure 1-16 In this invention, an easy-to-install anti-scouring device includes multiple PE pipes 6 installed on the slopes 102 on both sides of an open channel 1. Guide components 3 are detachably slidably connected to the PE pipes 6. Two opposing guide components 3 are connected by a waterproof cloth 2. The upper side of the waterproof cloth 2 is connected to the PE pipes 6, and the lower side of the waterproof cloth 2 is connected to the PE pipes 6 through the guide components 3. The guide components 3 include a top seat 12, which is connected to a movable frame 10 through a support plate 11. Rollers 1007 are rotatably provided on both sides of the movable frame 10, and the rollers 1007 are supported on the slope 102.

[0018] As a temporary structure, the open channel 1 needs to ensure that the construction cost is controllable. The open channel in this project is relatively large, with a slope length (from the riverbed to the embankment) of tens of meters. The workload of laying geotextile is large and the construction is relatively complicated. At the same time, since the slope of the open channel is not completely flat, but has certain undulations and angle changes, the size and state of the waterproof fabric need to be adjusted according to the position changes. In order to ensure that the waterproof fabric has a stable anti-erosion effect, the waterproof fabric is best attached to the slope 102. Then, according to the reinforcement needs, it is stacked and piled on the waterproof fabric 2 in a regular manner. If necessary, the insert rod is used to directly penetrate the geotextile bag and the waterproof fabric 2 and hammer it into the slope 2 to improve the overall anti-erosion effect.

[0019] Since the length of the waterproof cloth 2 is limited, it is impossible to lay it along the slope 102 without any interruption. The improper laying will not result in a good fit, and there will be many inconveniences in adjustment. First, the PE pipe 6 is arranged at reasonable intervals according to the slope direction and tilt angle and fixed to the slope 102. Then, the guiding device moves the waterproof cloth 2 from one side of the riverbank 101 to the bottom of the slope 102 (near the riverbed side). Then, the waterproof cloth 2 is fixed to the PE pipe by traction.

[0020] In the preferred embodiment, the PE pipe 6 is fixed to the slope 102 by the locking nail 17, and the two sides of the PE pipe 6 are also provided with a first fixing head 8, which is connected to the waterproof cloth 2 by the connecting cable 21.

[0021] According to the needs of the site, the waterproof cloth 2 can be fixed by the first fixing head 8 after it has been laid.

[0022] In a preferred embodiment, the first fixing head 8 includes a plug 801 and a straight plate 802. A locking hole 803 is provided through the straight plate 802. The plug 801 is located inside the PE pipe 6. A second fixing head 203 is provided on the upper side of the waterproof cloth 2. A first through groove 204 is provided through the second fixing head 203. The two sides of the connecting cable 21 are respectively inserted into the locking hole 803 and the first through groove 204.

[0023] Because it's impossible to completely eliminate any loose stones or sharp stones that could scratch the waterproof fabric 2 during the laying process, damage to the waterproof fabric 2 may occur. When such damage is discovered, timely repair is necessary. If damage occurs during laying, the punctured portion can be turned over using the guide component 3 for repair. Through the cooperation of the guide component 3, motor 4, and connecting cable 21, the position and state of the waterproof fabric 2 can be easily adjusted, ensuring convenience during the laying process. Furthermore, since traditional waterproof fabric 2 laying requires a specific sequence, when the first layer of waterproof fabric... After the water-resistant fabric 2 is laid, the subsequent waterproof fabric 2 needs to overlap to a certain extent before proceeding. This solution allows the two waterproof fabrics 2 to be laid in staggered time. During use, the PE pipe 6 is only fixed with locking nails 17 on both sides and in the middle. After the two sides are laid, since the PE pipe is flexible, the middle of the PE pipe is grasped and lifted, forming a gap between the PE pipe 6 and the slope 102. The locking nail 17 in the middle is then pulled out from the slope 102. Then, the two adjacent waterproof fabrics 2 are stacked in an up-down order, ensuring convenient operation. After the overlap is completed, the PE pipe 6 is fixed again, which can cope with the scouring of the water and reduce waves.

[0024] The PE pipe is placed from the riverbank 101 to the bottom along the slope direction. Then, the locking nail 17 is driven into the PE pipe from the top until it passes through the inside of the PE pipe. Finally, the PE pipe is fixed to the slope 102. The PE pipe also serves as a separator, blocking the scouring water flow and absorbing the waves.

[0025] After the waterproof cloth 2 is laid, a fixing head 8 is installed at the bottom of the PE pipe 6 (on the side closest to the riverbed). The fixing head 8 and the connecting cable 21 are used to fix the waterproof cloth 2 to the PE pipe 6, thereby ensuring the stability of the waterproof cloth 2, good adhesion, strong anti-erosion ability, and without causing major damage to the waterproof cloth 2 itself.

[0026] In the preferred embodiment, two servo motors 13 are symmetrically arranged on the top of the top seat 12. The servo motors 13 are equipped with lock heads 14. A fixing plate 205 is provided on the lower side of the waterproof cloth 2. Two second through slots 206 are provided through the fixing plate 205. The lock head 14 includes a mounting plate 1401 and an arc rod 1402. The arc rod 1402 passes through the two second through slots 206.

[0027] As previously described, after the waterproof fabric 2 is laid, the guide assembly 3 is removed, and then the connecting cable 21 is used to fix the waterproof fabric 2 through the fixing head 8 and the second through slot 206. Since the waterproof fabric 2 is at risk of damage during installation and use, timely replacement and maintenance are necessary. Because each piece of waterproof fabric 2 requires two guide assemblies 3, there is a situation where the guide assemblies 3 of adjacent waterproof fabric 2 are mutually constrained; the upper guide assembly 3 will block the lower guide assembly 3. Therefore, it is troublesome when two adjacent waterproof fabric 2 need to be replaced. At this time, the locking heads 14 on the top seat 12 can cooperate to release the locking head 14 that originally passed through the lower guide assembly 3, and instead lock the locking head 14 of the upper guide assembly 3. The two adjacent waterproof fabric 2 exchange their respective cooperating guide assemblies 3. The design is ingenious and the effect is good. The rotation angle of the locking head 14 can be changed by the servo motor 13, thereby locking or releasing the waterproof fabric 2.

[0028] After all the waterproof fabric 2 has been laid, the guide component 3 located on the lower side is disassembled, and then the fixing head is installed on the lower side of the PE pipe 6. Similarly, after the open channel has completed its overall function, backfilling is required, and drainage is carried out. Then, the guide component 3 is reinstalled on the lower side of the PE pipe 6, the fixing head 8 and connecting cable 21 are removed, and the waterproof fabric 6 is recycled and centrally processed. Physical, chemical or biological methods are selected according to the material type for final reuse or energy conversion, ensuring high material utilization and avoiding the problem of soil pollution caused by direct on-site burial. Currently, industry analysis and prospect reports on fiberglass waterproof fabric indicate that new projects need to clearly define the waterproof material recycling plan in the construction scheme to promote recycling. Because water conservancy projects have high requirements for the performance and structure of waterproof fabric, synthetic geotextiles are generally used. Geotextiles are generally made of polyester fibers, and traditional polyester fiber waterproof fabrics have a long degradation cycle, which may take decades to completely decompose in the natural environment. During degradation, microplastic particles may be released, potentially impacting the environment. For example, the degradation of polyester and polypropylene materials produces microplastic particles that may pollute soil and water bodies. Chemicals such as UV stabilizers and flame retardants added to waterproof fabrics may be released into the environment during degradation, and the degradation products of waterproof fabrics may alter the physical and chemical properties of the soil. Therefore, it is necessary to strengthen the recycling of traditional waterproof fabrics to avoid direct disposal and environmental pollution.

[0029] In a preferred embodiment, the top seat 12 includes a top plate 1201, and a T-shaped plate 1203 is provided at the bottom of the top plate 1201. The T-shaped plate 1203 is connected by two parallel support plates 11 and two movable frames 10.

[0030] During the laying of the waterproof cloth 2, the roller 1007 is attached to the slope surface to unfold the waterproof cloth 2 and pull it to the riverbed. The roller 1007 ensures smooth movement. At the same time, the top seat 12 and the support frame 11 are connected by a soft connection, which can be adaptively adjusted according to the changes in the slope 102.

[0031] In the preferred embodiment, two columns 15 are arranged in parallel at the middle of the top seat 12, and two annular grooves 16 are arranged in parallel on the columns 15. The columns 15 are connected to the winding drum 5 by the pull rope 7. The winding drum 5 is set on the output shaft of the motor 4, and the motor 4 is located on the river embankment 101.

[0032] When the waterproof cloth 2 is damaged and needs to be replaced directly, the motor 4 is used in conjunction with the winding drum 5 to lift the waterproof cloth 2 from the riverbed side to the riverbank 101 by pulling the rope 7 and driving the top seat 12. Then, it is disassembled and replaced, avoiding the problem of inconvenience for personnel to operate on the slope 102. At the same time, after the replacement is completed, the working area covering the original waterproof cloth 2 can be accurately restored. The overall versatility is high and the effect is good.

[0033] In the preferred embodiment, the top two sides of the waterproof cloth 2 are symmetrically provided with fixing straps 201, and the ends of the fixing straps 201 are provided with locking rings 202. The motor 4 is connected to the fixing straps 201 through the storage assembly 9. The storage assembly 9 includes a rotating rod 901. One side of the rotating rod 901 is connected to the output shaft of the motor 4 through a coupling 902, and the other side of the rotating rod 901 is supported on the river embankment 101 through a support frame 903. The rotating rod 901 passes through the two locking rings 202. To ensure convenient installation, relatively long locking pins can be selected on both sides of the PE pipe 6, while relatively short locking pins can be selected in the middle. After removing the middle locking pin 7 from the slope 102, a gap is formed between the PE pipe 6 and the slope 102. At this time, the waterproof cloth 2 on both sides can be adjusted from the overlapping state to the opposite state and placed on both sides of the PE pipe 6. Then, the guide component 3 is installed to fix the waterproof cloth 2. The overall collection is completed by the storage component 9 and the motor 4.

[0034] When the waterproof cloth 2 is undamaged and needs to be stored after use, it can be rolled up using the rotating rod 901. After rolling, the rotating rod 901 can be pulled out from the middle of the roll of the waterproof cloth 2. Since the locking ring 202 is located on both sides, it is convenient to operate both during the installation and disassembly of the rotating rod 901.

[0035] In a preferred embodiment, two adapter ropes 19 are provided on one side of the pull rope 7, and a locking ring 20 is provided at the end of the adapter rope 19. The locking ring 20 is sleeved on the column 15 and is located in the annular groove 16.

[0036] Since the two guide components 3 block each other, the annular grooves 16 at different heights can avoid the mutual influence of the two pull ropes 7. At the same time, the two locking rings 20 apply force to the two columns 15, and the effect of evenly distributing the force avoids the problem of overturning caused by uneven load.

[0037] In the preferred embodiment, the T-shaped plate 1203 has a third through hole 1204 through both sides, and the support plate 11 has a second upright 1103 in the middle. The second upright 1103 passes through the third through hole 1204 and is connected to the T-shaped plate 1203 by a third spring 1206 and a third nut 1207. The second upright 1103 has two through holes 1101 on both sides. The top of the movable frame 10 has two first uprights 1011 symmetrically arranged. The first uprights 1011 pass through the second through holes 1101. The first uprights 1011 are connected to the support plate 11 by the second spring 1102 and the second nut 1104. The bottom of the movable frame 10 is provided with a first ball bearing 1012. Vertical plates 1002 are symmetrically provided on both sides of the first ball bearing 1012. A threaded hole 1015 is provided through the vertical plate 1002. The threaded hole 1015 is inclined to the bottom. An adjusting pin 1013 is inserted into the threaded hole 1015. A second ball bearing 1014 is provided at the end of the adjusting pin 1013. The second ball bearing 1014 and the first ball bearing 1012 are attached to the outer wall of the PE pipe 6.

[0038] Since the slope 102 has certain undulations, and the state of the slope 102 on both sides of the PE pipe 6 is also uncertain, there are different stress states of the rollers 1007 on the left and right sides. Therefore, the guide component 3 is moved smoothly and stably on the outside of the PE pipe 6 by two movable frames 10. At the same time, the parallelogram structure formed by two support plates 11 can adapt to the problem of the PE pipe 6 having certain bends and height undulations, and will not affect the ease of use of the top seat 12 located on the upper side.

[0039] In a preferred embodiment, the top of the movable frame 10 is provided with an adjusting plate 1001, and the two sides of the adjusting plate 1001 are provided with first through holes 1003. The top of the first through holes 1003 is provided with a limiting rod 1004, and a guide rod 1005 is inserted into the first through hole 1003. A sliding groove 1009 is provided on the outer side of the guide rod 1005, and the end of the limiting rod 1004 abuts against the sliding groove 1009. The guide rod 1005 is connected to the adjusting plate 1001 through a first spring 1008 and a first nut 1010. The bottom of the guide rod 1005 is provided with a square platform 1006, and the screw 18 passes through the roller 1007 and the square platform 1006. The screw 18 and the square platform 1006 are threaded together. The bottom of the vertical plate 1002 is provided with a protrusion 1018. The top plate 1201 has side plates 1202 on both sides, and the end of the side plate 1202 has a second oblique cut 1205. The outer side of the fixing plate 205 has a positioning plate 207, which is magnetically connected to the side plate 1202. The two ends of the positioning plate 207 have a first oblique cut 208. The surface of the waterproof cloth 2 is also detachably provided with multiple counterweights 209. The two sides of the adjusting plate 1001 are respectively provided with a conical hole 1016 and a conical head 1017, and the dimensions of the conical hole 1016 and the conical head 1017 are matched.

[0040] The guide rod 1005 is ensured to move up and down along the axis without angular deflection by the slide groove 1009 and the limiting rod 1004. Then, the first spring 1008 adapts to the state of the slope 102, which also avoids overall looseness and makes it easier to fit.

[0041] The cross-section of the protrusion 1018 is an inverted triangle. As the roller 1007 moves up and down against the slope 102, the contact area with the slope 102 is reduced, resulting in less frictional resistance.

[0042] The first oblique cut 208 and the second oblique cut 1205 cooperate with each other to ensure that the fixing plate 205 can be accurately aligned with the two guide components 3, thus completing the alignment of the two guide components 3. At the same time, since the two guide components 3 can achieve precise alignment, they can complete the correction of their own position through the conical hole 1016 and the conical head 1017, ensuring that the fixing plate 205 can fit on the side plate 1202. This makes it easy for the servo motor 13 to accurately lock or release the waterproof cloth 2 through the lock head 14, resulting in high operational precision and good effect.

[0043] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
