Description
TECHNICAL FIELD
[0001] The utility model relates to water conservancy engineering technical field, concretely relates to a dam embankment seepage prevention reinforcing device. BACKGROUND
[0002] In water conservancy engineering, the seepage prevention treatment of dam embankment is one of the key measures to ensure the safety and effective operation of the dam. The traditional seepage prevention method usually involves laying a seepage prevention membrane on the water-facing surface of the dam embankment. These seepage prevention membranes prevent water from penetrating by closely adhering to the surface of the embankment, thereby protecting the embankment structure and reducing water resource loss.
[0003] However, this method has some significant defects in practical application. The seepage prevention membrane itself usually does not have enough stretchability and elasticity to adapt to the uneven settlement and deformation of the dam embankment under natural conditions. As the embankment gradually settles and deforms, the seepage prevention membrane will be continuously stretched and stressed, leading to its easy cracking, tearing, or other forms of damage. Once the seepage prevention membrane is damaged, its seepage prevention function will be greatly reduced.
[0004] Therefore, a dam embankment seepage prevention reinforcing device is proposed. SUMMARY
[0005] The purpose of the utility model is to solve the problems raised in the background art. The utility model provides a dam embankment seepage prevention reinforcing device.
[0006] The utility model discloses a specific technical scheme to achieve the above-mentioned purpose:
[0007] A dam embankment seepage prevention reinforcing device, comprising a dam base and a water retaining dam embankment, the top surface of the water retaining dam embankment is pre-buried with a fixed anchor rod, and the top surface of the water retaining dam embankment is fixedly installed with an elastic structure through the fixed anchor rod and a nut, the top surface of the dam base and the water-facing surface of the water retaining dam embankment are provided with a mounting base, the elastic structure and the end surface of the mounting base are fixedly connected with a seepage prevention membrane, and the seepage prevention membrane is in close contact with the water-facing surface of the water retaining dam embankment.
[0008] Further, the inner part of the dam base is filled with a waterproof board, a grouting seepage prevention layer, and a waterproof cloth layer to increase the seepage prevention efficiency of the water retaining dam embankment.
[0009] Further, the elastic structure comprises a fixed seat fixedly installed on the top surface of the water retaining dam embankment through the fixed anchor rod and the nut, and a plurality of groups of guide rods are fixedly installed on the stepped surface of the fixed seat at equal intervals, the surface of the guide rod is slidably sleeved with a movable mounting plate, the surface of the movable mounting plate and the surface of the fixed seat are slidably arranged, the surface of the guide rod is sleeved with a reset spring, and the two ends of the reset spring are fixedly connected with the stepped surface of the fixed seat and the surface of the movable mounting plate.
[0010] Furthermore, the mounting base includes a mounting seat pre-embedded in the top surface of the dam base, the surface of the mounting seat is provided with threaded holes, and a connecting base is attached to the top surface of the dam base, with bolts inserted into the internal threads of the connecting base and the mounting seat.
[0011] Furthermore, the fixed base and the connecting base are fitted to the water-facing surface of the dam, and both ends of the geomembrane are fixedly connected to the end faces of the movable mounting plate and the connecting base, respectively, so that the geomembrane covers the water-facing surface of the dam.
[0012] Furthermore, the movable mounting plate has an L-shaped cross-section and slides against the water-facing side of the dam.
[0013] The beneficial effects of this utility model are as follows:
[0014] By installing a seepage-proof membrane on the water-facing side of the dam, and combining it with the water-proof board, grouting seepage-proof layer and waterproof cloth layer inside the dam foundation, a multi-layer seepage-proof structure is formed, which significantly improves the seepage-proof capacity of the dam bank and effectively reduces the loss of water resources.
[0015] When the embankment settles, the mounting base moves the geomembrane. The movable mounting plate slides along the guide rod and stretches the return spring. Through the elastic force of the return spring, the movable mounting plate can automatically adjust its position to keep the geomembrane taut and avoid damage to the geomembrane due to stretching.

[0026] like Figures 1 to 5As shown, a seepage prevention and reinforcement device for a dam bank includes a dam base 1 and a retaining dam 2. The top surface of the retaining dam 2 is pre-embedded with fixed anchor rods 3, and an elastic structure 4 is fixedly installed on the top surface of the retaining dam 2 by the fixed anchor rods 3 and nuts. An installation base 5 is provided on the top surface of the dam base 1 and the water-facing side of the retaining dam 2. An impermeable membrane 6 is fixedly connected to the end face of the elastic structure 4 and the installation base 5, and the impermeable membrane 6 is in contact with the water-facing side of the retaining dam 2. More specifically, the elastic structure 4 is fixedly installed on the top surface of the dam embankment 2 by means of nuts and fixed anchor rods 3. The mounting base 5 is fixed on the top surface of the dam base 1 and located at the connection between the dam base 1 and the dam embankment 2. The geomembrane 6 is fixed by the elastic structure 4 and the mounting base 5, so that the geomembrane 6 is elastically connected on the water-facing side of the dam embankment 2. During use, if settlement occurs, the geomembrane 6 will move along the surface of the dam embankment 2 via the mounting base 5, thereby stretching the elastic structure 4 and preventing the geomembrane 6 from being stretched and damaged.
[0027] The interior of the dam base 1 is filled with a water-resistant plate 7, a grouting anti-seepage layer 8, and a waterproof fabric layer 9 to increase the seepage prevention efficiency of the dam 2. More specifically, the water-resistant plate 7, the grouting anti-seepage layer 8, and the waterproof fabric layer 9 inside the dam base 1 enhance the seepage prevention of the dam 2 and extend its service life.
[0028] The elastic structure 4 includes a fixed seat 401 fixedly installed on the top surface of the dam 2 by fixed anchor rods 3 and nuts. Several sets of guide rods 402, equidistantly arranged, are fixedly installed on the stepped surface of the fixed seat 401. A movable mounting plate 403 is slidably fitted onto the surface of the guide rods 402. The movable mounting plate 403 and the surface of the fixed seat 401 are slidably arranged. A return spring 404 is fitted onto the surface of the guide rods 402. Both ends of the return spring 404 are fixed to the stepped surface of the fixed seat 401 and the surface of the movable mounting plate 403, respectively. More specifically, as settlement occurs, the geomembrane 6 is moved by the mounting base 5, causing the movable mounting plate 403 to move along the surface of the fixed seat 401 and the guide rods 402, thereby stretching the return spring 404. Under the elastic force of the return spring 404, the geomembrane 6 can be tightened via the movable mounting plate 403, thus adhering to the water-facing surface of the dam 2.
[0029] The mounting base 5 includes a mounting seat 501 pre-embedded in the top surface of the dam base 1. The surface of the mounting seat 501 has threaded holes, and a connecting base 502 is attached to the top surface of the dam base 1. Bolts 503 are threadedly inserted into the connecting base 502 and the mounting seat 501. More specifically, the connecting base 502 is fixed by threading the bolts 503 into the connecting base 502 and the mounting seat 501, thereby fixing the bottom end of the geomembrane 6.
[0030] The fixing base 401 and the connecting base 502 are attached to the water-facing surface of the dam 2, and both ends of the geomembrane 6 are fixedly connected to the end faces of the movable mounting plate 403 and the connecting base 502, respectively, so that the geomembrane 6 covers the water-facing surface of the dam 2. More specifically, by attaching the geomembrane 6 to the water-facing surface of the dam 2, the geomembrane 6 can provide a seepage prevention function for the dam 2.
[0031] The movable mounting plate 403 has an L-shaped cross-section and slides against the water-facing side of the dam 2. More specifically, the sliding of the movable mounting plate 403 on the water-facing side of the dam 2 allows it to accommodate the stretching of the geomembrane 6 caused by settlement.
[0032] In summary: the elastic structure 4 is fixedly installed on the top surface of the dam embankment 2 by means of nuts and fixed anchor rods 3, and the mounting base 5 is fixed on the top surface of the dam base 1 and located at the connection between the dam base 1 and the dam embankment 2. The geomembrane 6 is fixed by means of the elastic structure 4 and the mounting base 5, so that the geomembrane 6 is elastically connected on the water-facing side of the dam embankment 2. During use, if settlement occurs, the geomembrane 6 will move along the surface of the dam embankment 2 via the mounting base 5, thereby stretching the elastic structure 4 and thus preventing the geomembrane 6 from being stretched and damaged.
