Description

Technical Field

[0001] The utility model belongs to the technical field of reservoir reinforcement, and in particular relates to a reservoir dam body risk removal and reinforcement structure. Background Art

[0002] Reservoirs are important facilities in the water conservancy industry. Dams are the main structures of reservoirs, playing important functions such as flood control and water storage. The reliability of the dam body directly affects the stability of the reservoir.

[0003] A Chinese patent with publication number CN218027502U discloses a dam stabilization and risk removal reinforcement structure, which includes a steel mesh and a reinforcement layer. A reinforcement plate is provided on the side of the steel mesh away from the dam body, and a plurality of connecting strips are fixedly connected to the side of the reinforcement plate close to the steel mesh. A fixing strip is provided on the side of the steel mesh close to the reinforcement plate, and a sliding groove adapted to slide with the connecting strip is provided on the fixing strip. A limiting member is provided on the reinforcement plate for limiting the sliding direction of the reinforcement plate to be parallel to the length direction of the connecting strip.

[0004] However, in actual use, the reinforcement plate can only slide along the slide groove due to the restriction of the limiting part. When one of the reinforcement plates is damaged and needs to be replaced and maintained, the reinforcement plate can only slide along the slide groove to leave the dam body. As a result, the remaining reinforcement plates above need to be slid and removed before the reinforcement plate that needs maintenance can be taken out for maintenance. That is, the maintenance and replacement of the reinforcement structure in the later stage is more cumbersome, which is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a reservoir dam body risk removal and reinforcement structure to solve the above-mentioned problem that the later maintenance of the existing reinforcement structure is relatively complicated.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reservoir dam body risk removal and reinforcement structure, installed on the dam body, including

[0007] Steel mesh, fixed on the dam body;

[0008] The slide rail is arranged on the side of the steel mesh away from the dam body, and has a slide groove with a T-shaped cross section;

[0009] A slider is slidably fitted in the slide groove, and a connecting rod is fixed on a side of the slider away from the slide groove;

[0010] The reinforcing plate has a connecting hole on its side wall, a connecting rod is slidably inserted into the connecting hole, the reinforcing plate abuts against the slide rail, a connecting nut is threadedly sleeved on the connecting rod, and the connecting nut abuts against the side of the reinforcing plate away from the slide rail.

[0011] The principle and effect of this technical solution:

[0012] 1. The steel mesh is used to reinforce the existing structure of the dam body to prevent the rolling of soil and the like. Through the installation of slide rails, sliders and reinforcement plates, the reinforcement plates can cover the outside of the dam body, which is conducive to the maintenance, reinforcement or pouring of concrete inside the dam body. Through the setting of connecting rods, connecting holes and connecting nuts, the reinforcement plates can be disassembled relative to the sliders, so that when the reinforcement plates need to be maintained separately in the future, there is no need to disassemble and install the reinforcement plates one by one from top to bottom, thereby improving the maintenance efficiency.

[0013] 2. The T-shaped slide groove is set so that the slider can be limited by the slide groove while sliding in the slide groove, so that when the reinforcement plate is abutted on the slide rail through the connecting nut and the connecting rod, it can only move along the length direction of the slide rail, and through the abutment between the sliders, when the reinforcement plate is removed separately, although the lower reinforcement plate is detached from the upper reinforcement plate, the lower slider is still abutted against the upper slider, so that the upper reinforcement plate will not slide downward due to the detachment of the lower reinforcement plate, thereby improving the stability of the reinforcement plate.

[0014] The utility model is further configured as follows: a flange is provided on the top of the reinforcement plate, a step groove is provided on the side of the bottom of the reinforcement plate away from the slide rail, an outer baffle is detachably installed in the step groove, an accommodating cavity is provided between the outer baffle and the step groove, and the flange is adapted to the accommodating cavity.

[0015] The principle and effect of this technical solution: by setting a detachable outer baffle plate, the flange of the lower reinforcement plate can be inserted into the upper accommodating cavity, so that the upper and lower reinforcement plates form a whole, thereby improving the anti-penetration ability and the overall stability, and by disassembling and assembling the outer baffle plate, when the reinforcement plate needs to be maintained separately later, the outer baffle plate will not hinder the separation of the flange from the upper reinforcement plate, so that the reinforcement plates in the device can be disassembled and detached separately.

[0016] The utility model is further configured as follows: a fixing bolt is passed through the outer baffle plate, and an end portion of the fixing bolt is threadedly inserted into the side wall of the stepped groove.

[0017] The principle and effect of the technical solution: the setting of the fixing bolts enables the outer baffle to be installed in the step groove or removed from the step groove.

[0018] The utility model is further configured as follows: the cross section of the reinforcement plate is in an "Ω" shape, and a filling cavity is provided between the reinforcement plate and the steel mesh.

[0019] The principle and effect of this technical solution: the Ω-shaped setting enables the reinforcement plate to have a better resistance to water flow, that is, it can reduce the impact of water flow on the outer wall of the reinforcement plate, and the internal filling cavity has a larger space, which can accommodate more concrete, thereby further enhancing the resistance of the dam body.

[0020] The utility model is further configured to include a tie rod with a T-shaped cross section, the tie rod is located in the filling cavity, and one end of the tie rod is detachably connected to the reinforcement plate.

[0021] The principle and effect of this technical solution: by setting up the detachable tie bars, the tie bars can play a certain pulling role on the reinforcement plate after the concrete is poured, so as to enhance the stability of the reinforcement plate, and by disassembly, after the tie bars are fixed by the concrete, the separation of the tie bars and the reinforcement plate enables the reinforcement plate to be disassembled and assembled separately.

[0022] The utility model is further configured as follows: a retaining ring is fixed on the tie bar, the retaining ring abuts against the side of the reinforcement plate close to the slide rail, the end of the tie bar is slidably inserted into the reinforcement plate, and a limiting nut is threadedly sleeved on the tie bar, and the limiting nut abuts against the side of the reinforcement plate away from the slide rail.

[0023] The principle and effect of this technical solution are as follows: by rotating the limit nut to separate the limit nut from the reinforcement, the reinforcement plate can be moved along the length direction of the reinforcement, thereby realizing the separation of the reinforcement from the reinforcement plate, thereby preventing the reinforcement from interfering with the separate detachment of the reinforcement plate after concrete pouring, and by setting the retaining ring, the position of the reinforcement can be limited to prevent the end of the reinforcement from protruding too much, resulting in a smaller contact position between the reinforcement and the concrete, and to avoid the problem of too large a height required to lift the reinforcement plate during disassembly due to the excessive protrusion of the end of the reinforcement.

[0024] The utility model is further configured as follows: waterproof openings are symmetrically provided on both sides of the slide rail, and waterproof strips are inserted into the waterproof openings of two adjacent slide rails.

[0025] The principle and effect of this technical solution: The setting of the waterproof strip can bend the gap between two adjacent slide rails, so that river water is not easy to pass through the gap, thereby reducing the scouring of the dam body by the river water, that is, to assist in filling the gap between the left and right adjacent reinforcement plates.

The steel mesh 102 is fixed on the dam body 101, and a plurality of slide rails 201 are arranged side by side at intervals along the length direction (river direction) of the dam body 101. The slide rail 201 is arranged on the side of the steel mesh 102 away from the dam body 101. The slide rail 201 has a slide groove 202 with a T-shaped cross-section, and waterproof openings 203 are symmetrically opened on both sides of the slide rail 201. Waterproof strips 204 are commonly inserted in the waterproof openings 203 of two adjacent slide rails 201. A slider 301 is slidably matched in the slide groove 202, and a connecting rod 302 is fixed on the side of the slider 301 away from the slide groove 202.

[0040] A connecting hole 402 is provided on the side wall of the reinforcing plate 401, and the connecting rod 302 is slidably inserted into the connecting hole 402, so that the reinforcing plate 401 abuts against the slide rail 201, and a connecting nut 303 is threadedly sleeved on the connecting rod 302, and the connecting nut 303 abuts against the side of the reinforcing plate 401 away from the slide rail 201.

[0041] Among them, one reinforcement plate 401 corresponds to at least two sliders 301, and the two sliders 301 are symmetrical about the reinforcement plate 401, wherein there are no less than 2 connecting rods 302 on each side, and multiple reinforcement plates 401 are set to abut against the slide rail 201 along the length direction of the slide rail 201, and multiple reinforcement plates 401 are set to abut against the slide rail 201 along the length direction of the river channel.

[0042] The cross-section of the reinforcement plate 401 is "Ω"-shaped, and a filling cavity 408 is provided between the reinforcement plate 401 and the steel mesh 102. A tie rod 501 is arranged in the filling cavity 408. A retaining ring 502 is fixed on the tie rod 501. The retaining ring 502 abuts against the side of the reinforcement plate 401 close to the slide rail 201. The end of the tie rod 501 is slidably inserted into the reinforcement plate 401, and a limiting nut 503 is threadedly mounted on the tie rod 501.

There is an accommodating cavity 406 between the outer baffle plate 405 and the stepped groove 404, and the flange 403 is adapted to the accommodating cavity 406.

[0044] When in use, after the steel mesh 102 and the slide rail 201 are set, the worker places the reinforcement plates 401 one by one along the slide rail 201 on the dam body 101 by aligning the slider 301 with the slide rail 201, wherein a lower enclosure plate is required to be provided at the bottom of the bottom reinforcement plate 401 to cover the gap between the bottom of the reinforcement plate and the river channel, and then concrete is poured in the filling cavity 408 to reinforce and repair the outside of the dam body 101, and then when a single damaged reinforcement plate 401 needs to be maintained and replaced later, it can be repaired by turning the limit nut 503 and the connection Nut 303, so that the limit nut 503 and the connecting nut 303 release the pressure on the reinforcing plate 401, and then rotate the fixing bolt 407 to make the outer baffle plate 405 contact the limit of the flange 403. At this time, the reinforcing plate 401 can be removed from the slide rail 201, the connecting rod 302 and the tie rod 501, and then the new reinforcing plate 401 or the repaired reinforcing plate 401 is turned upside down on the dam body 101 according to the above steps.
