Description

Technical Field

[0001] The utility model relates to the field of diversion hole plugging, in particular to a concrete plug. Background Art

[0002] When constructing water conservancy and hydropower projects in mountainous rivers, cofferdams are often used to protect foundation pits to ensure that hydraulic structures are constructed on dry land, so that water can be discharged to the downstream through diversion tunnels. In the later stage of diversion construction, the diversion tunnel needs to be blocked to complete the reservoir water storage to meet the requirements of power generation, water supply, irrigation and other operations. The blocking method of the diversion tunnel is to first lower the gate to stop the water, and then cast concrete plugs in appropriate tunnel sections. In order to eliminate water seepage in the upstream tunnel body and water leakage from the inlet plugging gate during the plug construction, and to ensure the quality of the plug concrete casting, a drainage pipe is buried at the bottom of the plug to drain the accumulated water. After the plug construction is completed, the drainage pipe is sealed tightly with cement mortar.

[0003] During the use of the existing diversion hole plug, the diversion hole opening is sealed by a poured concrete plug. During the sealing process, the end of the plug facing the water flow is subjected to excessive force due to long-term impact of the water flow, resulting in severe erosion of the plug by the water flow and damage, thereby reducing the sealing effect and posing a safety hazard. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a concrete plug which can effectively improve the erosion resistance and impact resistance of the plug, avoid damage thereof, increase the service life and sealing effect, and prevent potential safety hazards in view of the current status of the prior art.

[0005] The utility model is achieved through the following technical scheme: the utility model proposes a concrete plug, including a plug, the plug including a platform for connecting to the ground and a plugging plate for sealing, and one side of the plugging plate is an inclined structure, a pressure-resistant component is installed on one side of the plugging plate, the pressure-resistant component includes a fixing frame installed on the outside of the plugging plate, a water storage bag is installed in the fixing frame, a plurality of water inlet holes are evenly opened at the bottom end of the water storage bag, and an empty groove is formed on the side of the plugging plate facing the inside of the pressure-resistant component.

[0006] By adopting the above technical scheme, when the blocking plate blocks the diversion hole, the water in the diversion hole will enter the empty groove on the blocking plate through the water inlet hole at the bottom of the water storage bag, and the water storage bag is installed on the outside of the empty groove through the fixing frame, so that water can enter the water storage bag of the pressure-resistant component, and the water storage bag is expanded by the entering water. The water levels inside and outside the water storage bag are the same, and during the flow of external water flow, the water flow directly impacts the water storage bag. At this time, the water storage bag is subjected to force to squeeze the water in the empty groove, and the water level in the empty groove rises, converting the horizontal impact force of the water flow to the vertical direction, thereby reducing the impact force of the water flow on the blocking plate.

[0007] Furthermore, the platform and the blocking plate are an integrated cast structure.

[0008] By adopting the above technical solution, the plug can be fixed at the opening of the diversion hole, thereby improving the stability of the plug.

[0009] Furthermore, an impact-resistant layer is provided on the outer sides of the platform and the blocking plate, and a steel bar braiding frame for support is provided in the middle of the platform and the blocking plate, and a concrete layer is provided between the impact-resistant layer and the steel bar braiding frame.

[0010] By adopting the above technical scheme, the compressive and bending strength of the plug can be improved through the concrete layer, so as to withstand the scouring and erosion of water flow; and the steel bar braided frame enhances the tensile performance of the concrete layer, and improves the overall stability of the plug; at the same time, the anti-scouring layer adopts special materials, which can effectively resist the scouring of water flow and prevent the plug from being damaged.

[0011] Furthermore, the fixing frame is a double-layer structure, and the fixing frame is located on the inner and outer sides of the water storage bag.

[0012] By adopting the above technical solution, the water storage bag can be installed on the inclined end of the blocking plate through the fixing frame, and the stability of the water storage bag is ensured.

[0013] Furthermore, a pressure-resistant plate is provided on the side of the empty slot facing the water storage bag, and the pressure-resistant plate has the same slope as the blocking plate.

[0014] By adopting the above technical solution, when the external water flow is too large, the pressure-resistant plate contacts the water flow to resist pressure, thereby reducing the impact force of the plug, and the pressure-resistant plate with an inclined structure can effectively unload the force.

[0015] Furthermore, the compression plate and the blocking plate are connected via a support column, and the support column is a concrete structure.

[0016] By adopting the above technical solution, the anti-compression plate can be fixed on the blocking plate through the support column, thereby ensuring the stability of the anti-compression plate.

[0017] Furthermore, a plurality of overflow holes are equidistantly arranged on the compression plate, and the overflow holes and the support columns are staggered with each other.

[0018] By adopting the above technical solution, the water entering the empty groove can be easily filled to the outside of the pressure-resistant plate through the overflow hole.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model provides an empty groove and a pressure-resistant component, so that when the plugging plate blocks the diversion hole, water in the diversion hole will enter the empty groove on the plugging plate through the water inlet hole at the bottom of the water storage bag, and the water storage bag is installed on the outside of the empty groove through a fixing frame, so that water can enter the water storage bag of the pressure-resistant component, and the water storage bag is expanded by the entering water, and the water levels inside and outside the water storage bag are the same. During the flow of external water flow, the water flow directly impacts the water storage bag. At this time, the water storage bag is subjected to force to squeeze the water in the empty groove, and the water level in the empty groove rises, converting the impact force of the water flow in the horizontal direction to the vertical direction, thereby reducing the impact force of the water flow on the plugging plate, avoiding damage to the plug, improving the service life and the plugging effect, and preventing safety hazards.

[0030] like Figure 3-Figure 4 As shown, the platform 101 and the plugging plate 102 are an integrated cast structure, which can fix the plug 1 at the entrance of the diversion tunnel and improve the stability of the plug 1; an impact-resistant layer 1121 is provided on the outer side of the platform 101 and the plugging plate 102. The anti-scouring layer is made of special materials and can effectively resist the scouring of water flow to prevent the plug 1 from being damaged, and a steel braided frame 1123 for support is provided in the middle of the platform 101 and the plugging plate 102. The steel braided frame 1123 enhances the tensile properties of the concrete layer 1122 and improves the overall stability of the plug 1. A concrete layer 1122 is provided between the impact-resistant layer 1121 and the steel braided frame 1123. The concrete layer 1122 is used to increase the compressive and bending strengths of the plug 1, thereby allowing it to withstand the scouring and erosion of water flow.

[0031] like Figure 3-Figure 5As shown, the fixing frame 201 is a double-layer structure, and the fixing frame 201 is located on both sides of the inner and outer sides of the water storage bag 202, so that the water storage bag 202 can be installed on the inclined end of the plugging plate 102 through the fixing frame 201, and the stability of the water storage bag 202 is ensured; a pressure-resistant plate 4 is arranged on the side of the empty slot 3 facing the water storage bag 202, and the pressure-resistant plate 4 has the same slope as the plugging plate 102.

When the external water flow is too large, the pressure-resistant plate 4 contacts with the water flow to resist pressure, thereby reducing the impact force of the plug 1, and the pressure-resistant plate 4 with an inclined structure can effectively unload force.

[0032] The specific implementation process of this embodiment is as follows: the staff installs a steel braided frame 1123 at the diversion hole according to the construction requirements, then builds a template and injects a concrete layer 1122 into it, and after the concrete dries, an impact-resistant layer 1121 is applied on its surface to form a plug 1, and the support column 5 and the compression plate 4 are correspondingly cast at the position of the empty slot 3, so that the compression plate 4 has the same inclination as the plugging plate 102, and overflow holes 6 are evenly opened on the compression plate 4, and then the compression component 2 is installed on the outside of the plugging plate 102, the fixing frame 201 is first installed on the outside of the empty slot 3, and then the water storage bag 202 is installed in the fixing frame 201;

The water entering the water storage bag 202 will expand, and the water levels inside and outside the water storage bag 202 are the same. During the flow of external water, the water flow directly impacts the water storage bag 202. At this time, the water storage bag 202 is subjected to force to squeeze the water in the empty slot 3. The water level in the empty groove 3 rises, converting the horizontal impact force of the water flow to the vertical direction, thereby reducing the impact force of the water flow on the plug 102, avoiding damage to the plug 1, improving the service life and sealing effect, and preventing safety hazards. The concrete layer 1122 can increase the compressive and bending strength of the plug 1, thereby withstanding the scouring and erosion of the water flow; and the steel braided frame 1123 enhances the tensile performance of the concrete layer 1122 and improves the overall stability of the plug 1; at the same time, the anti-scouring layer is made of special materials, which can effectively resist the scouring of the water flow and prevent the plug 1 from being damaged.
