Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of copper water-stopping protection devices, specifically to a copper water-stopping protection device for rockfill dams. Background Technology
[0002] In concrete-faced rockfill dams, copper waterstops are important structural components for preventing seepage in the dam body. They are used at the joints of the concrete-faced rockfill dam and, through their special structure and material properties, effectively prevent water from seeping through the joints, ensuring the dam's seepage prevention performance.
[0003] However, existing copper waterstops lack effective protective devices during dam construction and are easily damaged by construction workers. For example, when pouring concrete mortar to create the waterproof surface of the dam, construction workers need to manually handle the connection between the concrete and the mortar strip. Since the copper waterstop is located inside the mortar strip, construction workers often step on it because it is inconvenient to handle it. However, the copper waterstop itself has low strength and is easily damaged by construction workers.
[0004] Chinese patent application number 202220114026.9 discloses a copper waterstop protection device for concrete-faced rockfill dams, comprising: a steel frame, including a frame body and multiple sets of support structures consisting of fixing members three and support members two installed at the bottom of the frame body; a protective plate, including an upper plate, a side plate, and a lower plate; wherein the upper plate, side plate, and lower plate are respectively installed on the top, side, and bottom of the frame body to form a long groove-shaped protective structure; and the support members two are obliquely arranged at the bottom of the frame body, with the lower end of the support members two connected to the body of the fixing members three. This copper waterstop protection device for concrete-faced rockfill dams has several drawbacks. First, it requires expansion bolts to be fixed to the dam surface, which can damage the dam surface structure. Second, it requires fixing to both sides of the copper waterstop, making it inconvenient to pour concrete on one side of the copper waterstop. Third, it is cumbersome to assemble and disassemble.

[0015] The counterweights are arranged at intervals along the slope of the dam surface, with the uppermost counterweight fixed to the top surface of the rockfill dam, and adjacent counterweights connected by connecting rods.
[0016] The mounting base is provided with a socket hole, and the other end of the extension rod is inserted into the socket hole. The upper surface of the counterweight is provided with a connecting hole, and both ends of the connecting rod are provided with insertion posts.

[0030] Figures 1 to 4 This invention illustrates one embodiment of the copper waterstop protection device for a rockfill dam. The device includes multiple mounting bases 1 and protective covers 2. Each mounting base 1 is supported on the dam surface 91 of the rockfill dam 9 and located on one side of the copper waterstop 3 on the dam surface 91. The mounting bases 1 are spaced apart along the slope direction of the dam surface 91. The uppermost mounting base 1 is fixed to the top surface 92 of the rockfill dam 9. Each protective cover 2 is installed on an adjacent mounting base 1, and each protective cover 2 is spaced apart along the slope direction of the dam surface 91 (e.g., ...). Figure 1 The F-direction shown is sequentially set and placed above the copper waterstop 3.
[0031] During installation, first determine the position of the uppermost mounting base 1 and fix it on the top surface 92 of the rockfill dam 9. Then, alternately install the protective cover 2 and mounting base 1 from top to bottom along the slope direction, so that the mounting bases 1 are spaced apart along the slope direction of the dam surface 91. The protective covers 2 are sequentially set along the slope direction of the dam surface 91 and placed over the copper waterstop 3. Adjacent mounting bases 1 are connected by the protective covers 2 to form an integrated protective structure supported on the dam surface 91. Conversely, the mounting bases 1 and protective covers 2 can be removed alternately from bottom to top along the slope direction of the dam surface 91.
[0032] This copper waterstop protection device for rockfill dams has the following advantages: First, the fixing point of the entire device is on the top surface 92 of the rockfill dam 9, without damaging the dam surface 91 or the structure of the dam surface 91; Second, the load-bearing mounting base 1 is only set on one side of the copper waterstop 3, without affecting the concrete pouring construction on the other side of the copper waterstop 3; Third, it is easy to assemble and disassemble.
[0033] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the mounting base 1 is provided with a socket 11, and the protective cover 2 has insert rods 4 on both sides, which are inserted into the corresponding sockets 11. The insert rods 4 at both ends of the protective cover 2 are respectively inserted into the sockets 11 of adjacent mounting bases 1, connecting the adjacent mounting bases 1 together along the slope direction of the dam surface 91. The structure is simple and easy to assemble and disassemble. Specifically, the sockets 11 and the insert rods 4 are perpendicular to the extension direction of the copper waterstop 3 (generally set horizontally).
[0034] Furthermore, in this embodiment, as Figure 2 As shown, the mounting base 1 is provided with a limiting member 12 for limiting the position of the insertion rod 4. After the insertion rod 4 is inserted into the receiving slot 11, it is limited by the limiting member 12 to prevent the insertion rod 4 from falling out and improve the structural stability. The limiting member 12 can be a conventional component such as a locking screw, locking bolt, or locking pin, and the specific structure will not be described in detail.
[0035] Furthermore, in this embodiment, the protective cover 2 includes a frame 21 and a protective net 22 disposed within the frame 21, with the insert rod 4 disposed on the frame 21. Of course, in other embodiments, the protective cover 2 may also be a solid structure of one piece, but with a mesh structure in the middle, it will be heavier.
[0036] Furthermore, in this embodiment, the bottom surface of the mounting base 1 is provided with an anti-slip groove 13. The anti-slip groove 13 is used to increase the friction between the mounting base 1 and the dam surface 91, thereby improving the stability of the mounting base 1.
[0037] Furthermore, in this embodiment, mortar strips 5 are respectively provided on both sides of the copper waterstop 3 on the dam surface 91, and a side support plate 14 is provided on the side of the mounting base 1 facing the copper waterstop 3, with the side support plate 14 abutting against the corresponding mortar strip 5. The mounting base 1 abuts against the mortar strip 5 through the side support plate 14, which facilitates the arrangement of mounting bases 1 at intervals along the extension direction of the copper waterstop 3 on one side, thereby facilitating the alignment and installation of the protective cover 2 and the mounting base 1. Specifically, both the copper waterstop 3 and the mortar strips 5 extend along the slope direction of the dam surface 91.
[0038] Furthermore, in this embodiment, as Figure 1 and Figure 4 As shown, each mounting base 1 is equipped with an extension rod 6 extending away from the copper waterstop 3. Each extension rod 6 has a counterweight 7 at the end away from the mounting base 1, and each counterweight 7 is supported on the dam surface 91 of the rockfill dam 9. The counterweight 7 and the extension rod 6 can balance the force of the protective cover 2 on the other side of the mounting base 1, forming a lever balance effect and preventing the protective cover 2 from causing the mounting base 1 to tilt.
[0039] Furthermore, in this embodiment, the counterweights 7 are arranged at intervals along the slope direction of the dam surface 91, with the uppermost counterweight 7 fixed to the top surface 92 of the rockfill dam 9. Adjacent counterweights 7 are connected by connecting rods 8. During installation, the position of the uppermost counterweight 7 is first determined and fixed to the top surface 92 of the rockfill dam 9. Then, the counterweights 7 and connecting rods 8 are installed alternately from top to bottom along the slope direction, so that the counterweights 7 are arranged at intervals along the slope direction of the dam surface 91, and the connecting rods 8 are sequentially set along the slope direction of the dam surface 91. Adjacent counterweights 7 are connected by connecting rods 8 to form an integrated structure supported on the dam surface 91. Conversely, the counterweights 7 and connecting rods 8 can be removed alternately from bottom to top along the slope direction of the dam surface 91. This method is convenient for assembly and disassembly.
[0040] Furthermore, in this embodiment, as Figure 4 As shown, the mounting base 1 has a socket 15, and the other end of the extension rod 6 is inserted into the socket 15. The upper surface of the counterweight 7 has a connecting hole 71, and both ends of the connecting rod 8 have insertion posts 81. The insertion posts 81 at both ends of the connecting rod 8 are respectively inserted into the connecting holes 71 of the adjacent mounting base 1. The extension rod 6 is connected to the mounting base 1, and the connecting hole 71 is connected to the counterweight 7 by insertion, which is simple in structure and easy to assemble and disassemble.
[0041] Furthermore, in this embodiment, a first fixing block 93 and a second fixing block 94 are provided on the top surface 92 of the rockfill dam 9. The uppermost mounting base 1 is fixed to the first fixing block 93, and the uppermost counterweight block 7 is fixed to the second fixing block 94. Preferably, both the first fixing block 93 and the second fixing block 94 can be fixed to the top surface 92 of the rockfill dam 9 by bolts.
[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
