Detailed implementation manners
[0030] The following further elaborates on the present application with reference to the accompanying drawings.
[0031] An embodiment of the present application discloses a novel impervious body for reservoir basin construction. Referring to Figure 1 and Figure 2 , it includes a reservoir basin 1, a reservoir bank 2, and an impervious structure 3. The reservoir bank 2 is arranged on both sides of the reservoir basin 1. The reservoir basin 1 and the reservoir bank 2 form a reservoir structure. The impervious structure 3 is arranged at the connection between the reservoir bank 2 and the reservoir basin 1. The impervious structure 3 is used to enhance the waterproof ability of the reservoir and reduce the probability of water seeping into the ground from the connection between the reservoir basin 1 and the reservoir bank 2 and causing a decrease in the strength of the reservoir structure.
[0032] Referring to Figure 1 and Figure 2 , an asphalt concrete impervious layer 11 is arranged on the reservoir basin 1. The asphalt concrete impervious layer 11 is formed by pouring asphalt concrete. The thickness of the asphalt concrete impervious layer 11 is 5 cm - 10 cm. The asphalt concrete impervious layer 11 hardens the surface of the reservoir basin 1, thereby reducing the degree of water erosion from the reservoir basin 1 downward.
[0033] Referring to Figure 1 and Figure 2 , a grouting curtain 12 is arranged on the reservoir basin 1. First, a drill vertically drills downward on the reservoir basin 1, and then cement mortar is poured into the hole, so that the grouting curtain 12 is formed after the cement mortar solidifies. After the cement mortar is poured into the hole, it can fill the fissures in the reservoir basin 1 to form a continuous water-blocking curtain, thereby enhancing the structural strength and waterproof ability of the reservoir basin 1.
[0034] Referring to Figure 1 and Figure 2 , the reservoir bank 2 includes a base layer 21, a cushion zone 22, a transition layer 23, and a rockfill layer 24. The rockfill layer 24 is formed by laying stones. The rockfill layer 24 is laid on the ground to form a protrusion. The transition layer 23 is laid on the rockfill layer 24. The transition layer 23 can adopt continuously graded natural gravel coarse material or blasted excavation stone material. The cushion zone 22 is laid on the transition layer 23. The cushion zone 22 can adopt continuously graded natural gravel fine material or artificial sand and gravel material. The base layer 21 is laid on the cushion zone 22. The base layer 21 can be laid by pouring cement mortar. The base layer 21 enables the surface of the reservoir bank 2 to have better structural strength and reduces the degree of the reservoir bank 2 collapsing due to water flow scouring the stones.
[0035] Reference Figure 1 In other embodiments, as shown in Figure 1 , a concrete layer 25 and a crushed stone layer 26 are provided at the bottom of the rockfill layer 24. The concrete layer 25 is laid on the ground, the crushed stone layer 26 is laid on the concrete layer 25, and the rockfill layer 24 is laid on the crushed stone layer 26. The concrete layer 25 can endow the bottom of the reservoir bank 2 with better structural strength, thereby enhancing the overall stability of the reservoir bank 2.
[0036] Reference Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , the anti-seepage structure 3 includes a geocomposite membrane 31, a rapid-setting rubber asphalt waterproof coating layer, a waterproof board 33, an HDPE membrane 34, a pressing plate layer 35 and a sand cushion layer 36. The anti-seepage structure 3 is laid on the reservoir bank 2 and extends to the surface of the reservoir basin 1. The anti-seepage structure 3 is arranged at the connection between the reservoir bank 2 and the reservoir basin 1, thereby reducing the probability of water seeping from the connection between the reservoir bank 2 and the reservoir basin 1 and eroding the reservoir bank 2.
[0037] Reference Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , the geocomposite membrane 31 is laid on the surfaces of the reservoir basin 1 and the reservoir bank 2. One side of the geocomposite membrane 31 is laid and connected to the reservoir basin 1, and the other side is laid and connected to the reservoir bank 2. The geocomposite membrane 31 is laid on the asphalt concrete anti-seepage layer 11. The geocomposite membrane 31 provides a basic anti-seepage barrier. The geocomposite membrane 31 has high strength, high toughness and good anti-aging performance, ensuring a long-term stable anti-seepage effect. A sand cushion layer 36 is arranged on the upper surface of the geocomposite membrane 31. The sand cushion layer 36 is made of well-graded, hard medium coarse sand, crushed stone, pebbles, etc., and is compacted in layers as the bearing layer of the foundation. The sand cushion layer 36 provides additional protection for the geocomposite membrane 31, can play a buffering role, and reduce the impact and wear of the upper layer materials on the geocomposite membrane 31. The geocomposite membrane 31 and the sand cushion layer 36 are horizontally laid on the asphalt concrete anti-seepage layer 11, and the cushion area 22 is covered on the geocomposite membrane 31 and the sand cushion layer 36.
[0038] Reference Figure 1 and Figure 2, a quick-setting rubber asphalt waterproof coating layer is laid above the sand cushion layer 36. Spraying quick-setting rubber asphalt waterproof coating is a waterproof, anti-seepage, anti-corrosion, and protective coating with excellent performance formed by a special process, which is composed of superfine, suspended, modified anionic and synthetic formulations (component A), and then mixed and reacted with a special curing agent (component B). The main components of the sprayed quick-setting rubber asphalt are composed of more than 2 kinds of high-performance modified emulsified rubber asphalt and chemical coagulation catalysts, and it is a two-component system with the characteristic of rapid initial solidification. The quick-setting rubber asphalt waterproof coating layer is formed by spraying special materials. Construction workers can spray special materials on the surface of the sand cushion layer 36 or the waterproof board 33 to form a quick-setting rubber asphalt waterproof coating layer, thereby achieving the effect of improving the overall waterproof ability of the anti-seepage structure 3. The waterproof board 33 is arranged above the sand cushion layer 36, and the waterproof board 33 is laid along the inclined direction of the cushion area 22. The waterproof board 33 is made of an anti-seepage material with a polymer as the basic raw material. An HDPE membrane 34 is covered above the waterproof board 33. The HDPE material is high-density polyethylene. The HDPE membrane 34 has better wear resistance, electrical insulation, toughness and cold resistance, good chemical stability, low water absorption, and better waterproof performance. A pressing plate layer 35 is covered above the HDPE membrane 34. The pressing plate layer 35 is used to cover the HDPE membrane 34, which can reduce the probability of the HDPE membrane 34 being scratched by sand and gravel in water.
[0039] Refer to Figure 1 and Figure 2 , the waterproof board 33 is laid along the surface of the reservoir bank 2. The waterproof board 33 is stacked thicker at the bottom of the reservoir bank 2 and thinner at the upper side of the reservoir bank 2. The waterproof board 33 is arranged between the cushion area 22 and the base layer 21 on the surface of the reservoir bank 2. The waterproof board 33 forms a thicker structure at the bottom of the reservoir bank 2, thereby further improving the waterproof ability at the connection between the reservoir basin 1 and the reservoir bank 2. The lower side of the waterproof board 33 is covered by the HDPE membrane 34, and the upper side is covered by the base layer 21.
[0040] Refer to Figure 3 , a grid frame 4 is arranged in the base layer 21. The grid frame 4 has better structural strength and can be made of materials such as metal or resin. The grid frame 4 is a mesh structure and has a certain thickness. When construction workers set the base layer 21 on the cushion area 22, they first lay the grid frame 4 on the cushion area 22, fix the edge of the grid frame 4 to the ground with an adhesive, and then can pour cement mortar on the grid frame 4 to form the base layer 21. The cement mortar submerges the grid frame 4 to form the base layer 21. The grid frame 4 can improve the structural strength of the base layer 21 in the base layer 21, thereby reducing the probability of the base layer 21 peeling off from the reservoir bank 2 under the erosion of flowing water, and then making the reservoir bank 2 have better safety.
[0041] The implementation principle of the embodiments of this application is as follows: By setting an asphalt concrete impervious layer 11 on the surface of the reservoir basin 1, the asphalt concrete can play the role of slowing down the erosion of flowing water. By opening holes at the bottom of the reservoir basin 1 and pouring cement mortar in the holes to form a grouting curtain 12, the water-blocking capacity of the reservoir basin 1 can be improved. By using gravel and concrete to pile up to form the reservoir bank 2 and laying a waterproof board 33 on the surface of the reservoir bank 2, the waterproof capacity of the reservoir bank 2 can be improved. By setting an impervious structure 3 at the connection between the reservoir basin 1 and the reservoir bank 2, the waterproof board 33 and the HDPE membrane 34 can play the role of slowing down the erosion of flowing water, which can reduce the probability of water seeping into the reservoir bank 2 from the connection between the reservoir basin 1 and the reservoir bank 2 and improve the overall structural strength of the reservoir.
[0042] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
