[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Embodiment 1: Please refer to Figure 1 、 Figure 2 A waterproof retaining wall, comprising a wall body 1, a plurality of drainage pipes 104 are fixedly installed at the inner bottom end of the wall body 1, the drainage pipes 104 are arranged through the front and back sides of the wall body 1, for timely guiding and draining the seepage water accumulated behind the wall to the outside of the wall body 1 in the rainy season or when the underground water level rises, so as to reduce the static pressure on the wall body 1, and a plurality of flow guide pipes 103 are vertically arranged in the wall body 1, a plurality of evaporation holes 102 are formed at the upper end of the wall body 1, the upper end of the flow guide pipe 103 is communicated with the evaporation hole 102, and the lower end is connected with the drainage pipe 104, for guiding part of the water in the soil body behind the wall to the evaporation hole 102 to accelerate the dissipation;

[0025] In order to improve the water evaporation efficiency, the top inclined surface of the wall body 1 is provided with a rectangular groove, and a heat collecting plate 101 for absorbing solar radiation heat is fixedly installed in the rectangular groove. A heat conduction device is arranged between the heat collecting plate 101 and the flow guide pipe 103. The heat conduction device can absorb and conduct the heat generated by the heat collecting plate 101, and transmit the heat to the surrounding area of the flow guide pipe 103, so as to improve the temperature of the water and soil moisture in the flow guide pipe 103, and promote the rapid evaporation.

[0026] Embodiment 2: please refer to Figures 2-4 A waterproof retaining wall, which is different from the embodiment 1, the inner pipe of the drain pipe 104 is fixedly installed with a filter screen 2, which is used for preliminary filtering of the silt or impurities entering the pipeline with water flow, preventing the drain pipe 104 from being blocked. A plurality of evaporation grooves 105 are arranged on the contact surface of the wall body 1 and the soil body, which can increase the contact area of the soil and the wall body 1, so as to improve the heat transfer efficiency and accelerate the evaporation of the soil moisture;

[0027] The heat conduction device includes a uniform heating grid 201 fixedly installed at the bottom end of the heat collecting plate 101. A plurality of heat conducting pipes 202 are fixedly installed at the inner end of the wall body 1. The heat conducting pipes 202 are located between two adjacent flow guide pipes 103, and the upper end of the heat conducting pipe 202 is fixedly connected with the uniform heating grid 201. The heat conducting pipe 202 is made of metal material, and is filled with inert gas and heat conducting aggregate. The inert gas is nitrogen, which is used to prevent the oxidation of the heat conducting pipe 202. The heat conducting aggregate is selected from one of graphite particles, silicon carbide particles, aluminum oxide powder and copper powder, which is used to improve the heat conduction efficiency of the heat conducting pipe 202.

[0028] After the heat collecting plate 101 is heated under the action of light, the heat is transmitted to the uniform heating grid 201, and then transmitted to each heat conducting pipe 202 by the uniform heating grid 201, so that the whole heat conduction system forms a stable heat diffusion path.

[0029] Further, the arrangement range of the heat collecting plate 101 and the uniform heating grid 201 is not limited to the inclined surface area of the top of the wall body 1, but can also extend to the vertical outer surface of the wall body 1, so that the solar radiation heat can be continuously received under different sunlight angles, and the heat energy collection efficiency is improved.

[0030] As Figures 3-5As shown, the surface of the flow guide pipe 103 is sleeved with a heat uniformizing cylinder 203, the outer surface of the heat uniformizing cylinder 203 is fixedly connected with a heat conduction cover plate 205, and the two adjacent heat conduction cover plates 205 are respectively fixedly connected with the bottom ends of the corresponding heat conduction pipes 202. The heat uniformizing cylinder 203 is made of ceramic material, and a plurality of metal conductors are embedded in the heat uniformizing cylinder 203 for enhancing the heat conduction and heat storage capacity. After the heat conduction pipes 202 transfer heat to the heat conduction cover plate 205, the heat conduction cover plate 205 can uniformly deliver heat to the heat uniformizing cylinder 203, so that the heat uniformizing cylinder 203 forms a stable temperature zone in the area covering the flow guide pipe 103, thereby continuously heating and evaporating the moisture or soil moisture in the flow guide pipe 103.

[0031] A plurality of heat partitions 206 are fixedly installed on the inner side of the heat uniformizing cylinder 203, the heat partitions 206 divide the internal space of the heat uniformizing cylinder 203 into a plurality of independent chambers, each chamber is filled with heat conduction liquid, specifically, the volume of the heat conduction liquid is less than the volume of the chamber, and a space for evaporation and gasification expansion is reserved at the top of the chamber, and a plurality of heating pipes 204 are fixedly connected to the outer surface of the heat uniformizing cylinder 203, the chambers formed between the heating pipes 204 and the two heat partitions 206 are communicated, and one end of each heating pipe 204 away from the heat uniformizing cylinder 203 is parallel to the evaporation groove 105.

[0032] Specifically, the heating pipes 204 are arranged obliquely, so that the heat conduction liquid in the heat uniformizing cylinder 203 can flow upward along the heating pipes 204 after being heated and evaporated, thereby heating the water-containing soil in the evaporation groove 105, increasing the local temperature of the soil body, and accelerating the evaporation of moisture. A plurality of evaporation grooves 105 can simultaneously obtain heat, realize continuous heating of the entire area of the adhered soil, make the moisture in the soil evaporate in time, and avoid the problem of reduced service life of the wall body 1 due to long-term humid state.

[0033] During the heating process, the water vapor entering the top end of the heating pipe 204 will condense into water droplets and fall back into the heat uniformizing cylinder 203 or the corresponding chamber again to participate in the heating and evaporation cycle, thereby realizing the recycling of heat. The heating pipe 204 is also made of ceramic material, and a metal heat conduction member is embedded in the heating pipe 204 to improve the heat conduction performance and overall heating efficiency.

[0034] The side surface of the wall body 1 is fixedly installed with an insertion block 3, and the end of the wall body 1 away from the insertion block 3 is provided with a matching insertion slot. Through the insertion and cooperation of the insertion block 3 and the insertion slot, the adjacent wall bodies 1 can be quickly connected and stably connected, so that the retaining wall structure can be continuously spliced according to the construction length to form an uninterrupted overall wall body 1, improving the overall structural integrity and extension.

[0035] Working principle:

[0036] Under the action of sunlight, the temperature of the heat collecting plate 101 on the surface of the wall body 1 gradually rises, and the absorbed heat is distributed to each heat conducting pipe 202 through the heat uniformizing grid 201, the heat conducting pipe 202 can transmit heat to the heat conducting cover plate 205 connected thereto after being heated, and the heat conducting cover plate 205 uniformly spreads the heat to the outer surface of the heat uniformizing cylinder 203, so that the heat uniformizing cylinder 203 forms a relatively stable temperature field in the area covering the flow guide pipe 103;

[0037] With the continuous rise of the temperature of the heat uniformizing cylinder 203, the heat conducting liquid in the internal chamber thereof is continuously heated and gradually evaporated, the generated steam flows upward along the heating pipe 204 under the action of pressure difference, and the steam flowing through the heating pipe 204 heats the cement-containing soil in the evaporation groove 105, so that the local temperature of the soil is raised, thereby accelerating the evaporation of water in the soil, since multiple evaporation grooves 105 can simultaneously receive heat from the heating pipe 204, the continuous and uniform heating of the soil layer region adhered to the wall body 1 is realized, the rapid evaporation of soil moisture in the region is effectively promoted, the problem that the structural strength is reduced due to the long-term humid state of the wall body 1 is avoided, and the service life of the wall body 1 is significantly prolonged.

[0038] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
