Description

Technical Field

[0001] This application belongs to the technical field of flood control dikes, specifically relating to a spliced ​​flood control sub-dike. Background Technology

[0002] During flood control, it is necessary to temporarily raise the dikes to prevent them from overflowing. There are two existing methods for raising dikes: one is to construct a waterproof dike using sandbags, and the other is to construct a modular dike.

[0003] The existing spliced ​​dam is composed of multiple sub-dams spliced ​​together. Each sub-dam includes a waterproof panel and a support frame. The waterproof panel is fixed on the support frame. The support frame is a triangular steel frame structure that can provide stable support for the waterproof panel.

[0004] During the splicing process, one side of the waterproof panel on one sub-dike overlaps the side of the waterproof panel on the other sub-dike, aligning the through holes on the two waterproof panels. Then, the connection between the two waterproof panels is secured with bolts and nuts to complete the splicing of the two sub-dikes. However, the above splicing method is prone to water seepage at the connection point of the two waterproof panels. Utility Model Content

[0005] This application provides a spliced ​​flood control sub-dike to solve the problem of water seepage that easily occurs in the splicing method of the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A modular flood control sub-dike is provided, comprising:

[0008] The triangular support has a supporting surface at the bottom and a water-blocking surface on one side.

[0009] A water baffle is attached to a water-blocking surface. The water baffle includes alternating protrusions and recesses, with a low-level recess and a high-level recess on each side. Both sides of the water baffle have corresponding connecting holes. The low-level recess can be stacked on the high-level recess of another water baffle to form a stacking area.

[0010] The sealing plate is hinged on one side to the protrusion adjacent to the high recess of the baffle plate, and has a storage position and a working position; the sealing plate has a through hole corresponding to the connection hole;

[0011] The sealing plate has a U-shaped structure. When the sealing plate is in the working position, it can fit against the side wall of the stacked area and fit against two adjacent protrusions to seal the stacked area.

[0012] In one possible implementation, the top and bottom ends of the hinged position of the sealing plate each have a coaxially arranged pivot; the baffle plate has a connecting protrusion at the pivot position, and the connecting protrusion has a through hole that rotatably engages with the pivot.

[0013] In one possible implementation, the shaft has external threads, the sealing plate has a threaded hole at its hinge position, and the shaft is threadedly engaged with the sealing plate.

[0014] In one possible implementation, the protrusion on which the baffle plate is hinged to the sealing plate has a first connecting portion, and the first connecting portion has a threaded hole;

[0015] When the sealing plate is in the retracted position, the through hole on the sealing plate is aligned with the threaded hole on the first connecting part.

[0016] In one possible implementation, the triangular bracket has a second connecting portion on one side of the high recessed portion, and the second connecting portion has a threaded hole aligned with the connecting hole;

[0017] When the low-position recessed portion is stacked with the high-position recessed portion of another baffle plate, the top and bottom of the low-position recessed portion contact the high-position recessed portion and the second connecting portion, respectively, and the connecting holes on the low-position recessed portion and the high-position recessed portion are aligned with the threaded holes on the second connecting portion.

[0019] In one possible implementation, the bottom end of the sealing plate is also lower than the height of the supporting surface, and the bottom end of the sealing plate is inserted into the soil at an angle along with the bottom end of the water-blocking plate.

[0020] In one possible implementation, the triangular support includes two triangular frames, with a plurality of first support beams connected to the bottom of the two triangular frames, and a plurality of second support beams connected to one side of the water-blocking surface of the two triangular frames; the triangular frames, the first support beams and the second support beams are fixed by welding.

[0021] In one possible implementation, at least two positioning blocks are connected to the back side of the baffle, each positioning block having a positioning hole; the second support beam has a through hole aligned with the positioning hole;

[0022] The positioning block is positioned to the second support beam by a pin, and the water baffle is welded to the second support beam.

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] Please refer to the following: Figures 1 to 7 This application describes a modular flood control sub-dike. The modular flood control sub-dike includes a triangular support 1, a water-retaining plate 2, and a sealing plate 3. The bottom of the triangular support 1 is a supporting surface, and one side is a water-retaining surface. The water-retaining plate 2 is connected to the water-retaining surface. The water-retaining plate 2 includes alternating protrusions 21 and recesses 22, with a low-level recess 23 and a high-level recess 24 on each side. Both sides of the water-retaining plate 2 have corresponding connecting holes 25. The low-level recess 23 can be stacked on the high-level recess 24 of another water-retaining plate 2 to form a stacking area. One side of the sealing plate 3 is hinged to the high-level recess of the water-retaining plate 2. The recess 24 has a storage position and a working position on the protrusion 21 adjacent to it; the sealing plate 3 has a through hole corresponding to the connecting hole 25; the sealing plate 3 has a Z-shaped structure, and when the sealing plate 3 is in the working position, the sealing plate 3 can fit against the side wall of the stacking area and can fit against the two adjacent protrusions 21 to seal the stacking area; the water baffle 2 is made of fiberglass; the connection method between the triangular bracket 1 and the ground is the prior art and will not be described in detail here; the flood control sub-dike in this application is suitable for sites without obvious protrusions, and the site can be sandy loam, loam and clay.

[0035] This application provides a spliced ​​flood control sub-dike. Compared with the prior art, the sealing plate 3 is first rotated to the working position, and then the low-position recess 23 of one water-retaining plate 2 is stacked with the high-position recess 24 of the other water-retaining plate 2. At this time, the sealing plate 3 can fit the stacked area. After fixing the sealing plate 3, the high-position recess 24 and the low-position recess 23 with bolts and nuts, the sealing plate 3 can seal the stacked area, improve the sealing effect and reduce water seepage in the stacked area. The triangular bracket 1 can provide stable support for the water-retaining plate 2. Through the above settings, the waterproof performance of the connection position of the two water-retaining plates 2 can be improved.

[0036] When splicing two flood control sub-dikes, the lower recess 23 of one water-retaining plate 2 is inserted into the bottom of the upper recess 24 of the other water-retaining plate 2, and the top of the lower recess 23 contacts the bottom of the upper recess 24. At this time, the connecting hole 25 on the lower recess 23 is aligned with the connecting hole 25 on the upper recess 24. After the threaded end of the bolt passes through the sealing plate 3, the upper recess 24 and the lower recess 23, the connection position of the two water-retaining plates 2 can be fixed by the cooperation of the nut and the bolt.

[0037] The outer peripheral wall of the sealing plate 3 has a rubber layer. After being fixed by bolts, the rubber layer can fit tightly against the connection position of the two baffle plates 2, thus achieving a sealing effect at the connection position of the two baffle plates 2.

[0038] When splicing the two baffles 2, first rotate the sealing plate 3 to the position of the high recess 24, and then insert the low recess 23 on the other baffle 2 into the bottom of the high recess 24; to avoid the situation where the sealing plate 3 cannot be rotated to the working position after the low recess 23 and the high recess 24 are stacked.

[0039] For example, the triangular bracket 1 includes two triangular frames 11, with a plurality of first support beams 12 connected to the bottom of the two triangular frames 11, and a plurality of second support beams 13 connected to one side of the water-blocking surface of the two triangular frames 11; the triangular frames 11, the first support beams 12 and the second support beams 13 are fixed by welding.

[0040] In some embodiments, such as Figures 1 to 7 As shown, the top and bottom ends of the sealing plate 3 at the hinge position have coaxially arranged rotating shafts 31; the baffle plate 2 has a connecting protrusion 26 at the rotating shaft 31 position, and the connecting protrusion 26 has a through hole that rotatably engages with the rotating shaft 31.

[0041] The top and bottom pivots of the sealing plate 3 are coaxially arranged, allowing the sealing plate 3 to rotate around the axis of the pivots 31. By providing a connecting protrusion 26 on the baffle plate 2 and rotating the pivot 31 in conjunction with the connecting protrusion 26, the sealing plate 3 can be hinged to the baffle plate 2.

[0042] In some embodiments, such as Figures 1 to 7 As shown, the rotating shaft 31 has external threads, and the hinge position of the sealing plate 3 has a threaded hole, with the rotating shaft 31 and the sealing plate 3 threadedly engaged.

[0043] When installing the sealing plate 3, first place the sealing plate 3 between the two connecting protrusions 26 and align the threaded hole on the sealing plate 3 with the through hole on the connecting protrusion 26; then pass the rotating shaft 31 through the through hole on the connecting protrusion 26 and thread it into the threaded hole on the sealing plate 3 to connect the rotating shaft 31 to the sealing plate 3.

[0044] It should be noted that when assembling the two flood control sub-dikes, the sealing plate 3 is first rotated to the working position; when the flood control sub-dikes are stored separately, the sealing plate 3 is rotated to the storage position. Therefore, the sealing plate 3 is not rotated frequently, reducing the possibility of the rotating shaft 31 separating from the sealing plate 3.

[0045] In some embodiments, such as Figures 1 to 7 As shown, the protrusion 21 on the baffle plate 2 that is hinged to the sealing plate 3 has a first connecting part 27, and the first connecting part 27 has a threaded hole; wherein, when the sealing plate 3 is in the retracted position, the through hole on the sealing plate 3 is aligned with the threaded hole on the first connecting part 27.

[0046] When the flood control sub-dike is stored separately, the sealing plate 3 is rotated to the storage position. At this time, the through hole on the sealing plate 3 is aligned with the threaded hole on the first connecting part 27. The position of the sealing plate 3 can be fixed by the bolt engaging with the threaded part 27. When the flood control sub-dike is transported, the sealing plate 3 and the water-blocking plate 2 can be kept relatively fixed.

[0047] In addition, the bolts connected to the first connecting part 27 can pass through the connecting holes 25 on the lower recess 23 and the higher recess 24. Therefore, when the number of the first connecting parts 27 is equal to the number of connecting holes 25, there is no need to prepare additional bolts. Only nuts are needed to bolt the two adjacent baffles 2 together.

[0048] For example, the triangular bracket 1 has a second connecting portion 14 on one side of the high recess 24, and the second connecting portion 14 has a threaded hole aligned with the connecting hole 25; wherein, when the low recess 23 is stacked with the high recess 24 of another baffle plate 2, the top and bottom of the low recess 23 contact the high recess 24 and the second connecting portion 14 respectively, and the connecting holes 25 on the low recess 23 and the high recess 24 are aligned with the threaded hole on the second connecting portion 14.

[0049] When the number of first connecting parts 27 is equal to the number of second connecting parts 14, since the second connecting parts 14 are provided with threaded holes, not only are bolts not needed, but nuts are also not needed; thus reducing the possibility of bolts and nuts being lost during transportation.

[0050] When splicing the two flood control sub-dikes, first unscrew the bolts on the first connecting part 27, rotate the sealing plate 3 to the working position, and then splice the two water-retaining plates 2 together; after passing the previously unscrewed bolts through the sealing plate 3, the high-position recess 24 and the low-position recess 23, they are threaded into the second connecting part 14; through the above process, the connection position of the two water-retaining plates 2 can be fixed.

[0051] In some embodiments, such as Figures 1 to 7 As shown, the bottom of the water-blocking plate 2 is lower than the height of the supporting surface, and the bottom of the water-blocking plate 2 is used to be inserted into the soil at an angle; the bottom of the sealing plate 3 is also lower than the height of the supporting surface, and the bottom of the sealing plate 3 is inserted into the soil at an angle along with the bottom of the water-blocking plate 2.

[0052] By setting the bottom of the water-retaining plate 2 to be lower than the height of the supporting surface, when installing the flood control sub-dike, the supporting surface of the triangular bracket 1 contacts the ground, and the part of the water-retaining plate 2 that is lower than the supporting surface is inserted into the soil at an angle, which can improve the protective ability of the water-retaining plate 2; by inserting the bottom of the sealing plate 3 at an angle into the soil, the sealing performance of the connection position of the two water-retaining plates 2 can be further improved.

[0053] A placement pit can be pre-dug to place the bottom of the water baffle 2 and the sealing plate 3. After the assembly is completed, the placement pit is then filled in.

[0054] In some embodiments, such as Figures 1 to 7 As shown, at least two positioning blocks 28 are connected to the back side of the baffle plate 2, and each positioning block 28 has a positioning hole; the second support beam 13 has a through hole aligned with the positioning hole; wherein, the positioning block 28 and the second support beam 13 are positioned by a pin, and the baffle plate 2 and the second support beam 13 are welded and fixed; the pin is interference-fitted with the second support beam 13, which can reduce the possibility of the pin coming off the second support beam 13 before welding.

[0055] Taking two positioning blocks 28 as an example, when installing the baffle 2 on the triangular bracket 1, first align the positioning holes of the two positioning blocks 28 on the baffle 2 with the through holes on the second support beam 13, and then pass the pin through the positioning block 28 and the second support beam 13. The pin is interference-fitted with the second support beam 13, which can position the baffle 2, making it easier for the operator to weld the baffle 2 onto the triangular bracket 1.

[0056] Since the height of the bottom of the baffle plate 2 is lower than the height of the support surface, when positioning the baffle plate 2 and the triangular bracket 1, the triangular bracket 1 is placed on the pad; when the baffle plate 2 is placed on the triangular bracket 1, the baffle plate 2 can be suspended in the air, so as to fix the baffle plate 2 in place, and then the baffle plate 2 is welded to the triangular bracket 1.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
