Description

Technical Field

[0001] The utility model belongs to the technical field related to water conservancy, and specifically relates to an assembled reservoir dam. Background Art

[0002] Prefabricated reservoir dam refers to a method of building reservoir dams using prefabricated components and on-site assembly technology. Compared with the traditional on-site casting method, prefabricated reservoir dams can reduce construction time, improve construction quality, and reduce environmental impact. In prefabricated reservoir dams, prefabricated flood control walls are an important structure used to prevent flood disasters when the reservoir dam breaks. Prefabricated flood control walls are usually composed of prefabricated concrete components, which can be manufactured in the factory and then transported to the site for assembly. In this way, prefabricated flood control walls can be built more quickly and accurately, improving the flood control capacity and safety of reservoir dams.

[0003] However, after installation, the prefabricated reservoir dam needs to be in direct contact with the water body and needs to withstand strong water pressure. As the water level rises, the water pressure on the prefabricated reservoir dam will increase. If water surges during the increase in water pressure, it will easily cause the prefabricated reservoir dam that directly resists the water body to be deformed and damaged in the backward direction, which will directly cause a breach. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled reservoir dam to solve the problem proposed in the above-mentioned background technology that as the water level rises, the water pressure on the assembled reservoir dam will increase, and if water surges occur during the increase in water pressure, it will easily cause the assembled reservoir dam that directly resists the water body to be deformed and damaged in the backward direction.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled reservoir dam, comprising a dam main frame and a dam panel arranged at the rear end of the dam main frame, the dam main frame and the dam panel are fixedly connected by welding, vertical compression brackets are connected to the inner walls at the upper and lower ends of the dam main frame, horizontal compression brackets are connected to the inner walls at the left and right ends of the dam main frame, the vertical compression brackets and the horizontal compression brackets are fixedly connected to the dam main frame by welding, and an arched compression device is arranged at the rear end of the vertical compression bracket;

[0006] The arched pressure-resistant device includes an arched spring plate A, an arched spring plate B and a pressure-resistant welding plate. The pressure-resistant welding plate is fixed to the rear end of the vertical pressure-resistant bracket by welding. The arched spring plate A and the arched spring plate B are respectively connected to the outer walls at the upper and lower ends of the back of the pressure-resistant welding plate. The arched spring plate B is located inside the arched spring plate A.

[0007] Preferably, both ends of the arched spring plate A and the arched spring plate B are fixedly connected to the compression-resistant welding plate by welding, the arched spring plate A and the arched spring plate B are both made of spring steel, and the arch amplitude of the arched spring plate A is greater than the arch amplitude of the arched spring plate B.

[0008] Preferably, a transverse connecting bracket is fixed to the rear end of the bottom of the dam main frame by multiple bolts, a longitudinal ground bracket A is welded to the left end of the transverse connecting bracket, and a longitudinal ground bracket B is welded to the right end of the transverse connecting bracket, and the longitudinal ground bracket A and the longitudinal ground bracket B are parallel to each other.

[0009] Preferably, the inner corners where the longitudinal ground bracket A and the main frame of the dam are joined, as well as the inner corners where the longitudinal ground bracket B and the main frame of the dam are joined are connected with triangular connecting frames, and both ends of the triangular connecting frames are fixedly connected to the main frame of the dam, the longitudinal ground bracket A and the longitudinal ground bracket B respectively by bolts.

[0010] Preferably, the top of the rear end of the longitudinal ground-mounted bracket A is connected to the rear end of the top of the main frame of the dam with a diagonal brace bracket A, and the top of the rear end of the longitudinal ground-mounted bracket B is connected to the rear end of the top of the main frame of the dam with a diagonal brace bracket B. Assembly connecting plates are welded on the back of the left and right ends of the main frame of the dam.

[0011] Preferably, an assembling slot is provided inside the right end of the main frame of the dam, and an assembling insert is provided on the outer wall of the left end of the main frame of the dam, and the assembling insert can be completely inserted into the assembling slot.

[0012] Compared with the prior art, the utility model provides an assembled reservoir dam, which has the following beneficial effects:

[0013] The utility model adds a novel arched pressure-resistant device to the rear end of the vertical pressure-resistant support of the assembled reservoir dam. The arched pressure-resistant device can greatly increase the pressure resistance of the vertical pressure-resistant support to water pressure. When the water level of the reservoir is deep, the water pressure acting on the assembled reservoir dam will be very strong. Once the water flow surges, it will easily cause the vertical pressure-resistant support to bend backward. The arched pressure-resistant support on the back of the vertical pressure-resistant support can make full use of the arched support structure of the two groups of arched spring plates to completely resist the strong water pressure. The two groups of arched spring plates at the rear end of the vertical pressure-resistant support can support the upper and lower ends of the vertical pressure-resistant support like an arched bridge, thereby avoiding the situation where the top and bottom ends of the vertical pressure-resistant support are bent backward and deformed due to the strong water pressure. This can ensure that the assembled reservoir dam can be used for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

The assembly strip 14 can be fully inserted into the assembly slot 8. When assembling the assembled reservoir dam, the main frame 13 of the dam and the longitudinal ground bracket A1 and the longitudinal ground bracket need to be placed on the ground to be assembled first, and then the diagonal brace bracket A2 and the diagonal brace bracket B7 need to be connected obliquely between the longitudinal ground bracket A1 and the main frame 13 of the dam and the longitudinal ground bracket B6 and the main frame 13 of the dam, respectively, so that the diagonal brace bracket can produce a supporting effect at the rear end of the main frame 13 of the dam, so that the main frame 13 of the dam can withstand greater pressure, and then the longitudinal ground bracket A1 and the longitudinal ground bracket B6 need to be connected obliquely between the longitudinal ground bracket A1 and the main frame 13 of the dam and the longitudinal ground bracket B6 and the main frame 13 of the dam ... respectively, so that the diagonal brace bracket can produce a supporting effect at the rear end of the main frame 13 of the dam, so that the main frame 13 of the dam can withstand greater pressure, and then the longitudinal ground bracket A1 and the longitudinal ground bracket B6 need to be connected obliquely between the longitudinal ground bracket A1 and the main frame 13 of the dam and the longitudinal ground bracket B6 and the main frame 13 of the dam, so that the longitudinal ground bracket A1 and the longitudinal ground bracket B6 and the The ground-mounted bracket A1, the longitudinal ground-mounted bracket B6 and the transverse connecting bracket 4 are fixed to the ground by special bolts, and then a new prefabricated reservoir dam is installed on the left or right end of the installed prefabricated reservoir dam in the same way.
