[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example 1

[0036] See also Figure 1 , Figure 2 and Figure 5 The utility model provides the following technical solutions: a waterproof structure of a water conservancy building dam, including a waterproof inclined plate 11, a plurality of waterproof inclined plates 11 are spliced ​​end to end to form a waterproof mechanism 1, and also includes: a C-shaped water guide frame 12 and a waterproof membrane 13.

[0037] Specifically, by Figure 1 and Figure 2 As shown, in this embodiment, C-shaped water guide frames 12 are fixed on both left and right ends of the waterproof inclined plate 11, and a water guide channel 121 is formed on the inner side of the two C-shaped water guide frames 12 after being butted together, and a waterproof membrane 13 is laid on the inner side of the water guide channel 121. Therefore, when in use, multiple waterproof inclined plates 11 are spliced ​​end to end to form a waterproof mechanism 1 and laid on the inclined surface of the dam body. At this time, two adjacent C-shaped water guide frames 12 are butted together to form a water guide channel 121, and a waterproof membrane 13 is laid in the water guide channel 121. Rainwater that penetrates into the splicing gap of the waterproof inclined plate 11 will enter the water guide channel 121 and flow out along the inclined surface of the water guide channel 121, thereby preventing rainwater from extending into the soil foundation of the dam body, thereby greatly improving the waterproof effect and safety.

[0038] The waterproof membrane 13 is preferably a HDPE membrane, that is, a high-density polyethylene membrane, which has excellent anti-corrosion performance, electrical properties, moisture-proof performance, anti-leakage performance, and high tensile strength.

[0039] Optionally, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the waterproof inclined plate 11 includes: an inclined portion 111, an upper horizontal portion 112 and a lower horizontal portion 113, the upper horizontal portion 112 is fixed at the top of the inclined portion 111, and an upper water retaining plate 1121 is fixed to the bottom surface of the upper horizontal portion 112, the lower horizontal portion 113 is fixed to the bottom end of the inclined portion 111, and a lower water retaining plate 1131 is fixed to the bottom surface of the lower horizontal portion 113, the upper horizontal portion 112 and the lower horizontal portion 113 are used as mounting portions, which are respectively fixed to the top and bottom ends of the dam body to achieve a stable setting of the inclined portion 111, the upper water retaining plate 1121 and the lower water retaining plate 1131 are both set to a vertical shape in this embodiment, and can also be designed to be inclined, on the one hand to achieve the installation function, to ensure the stability of the waterproof inclined plate 11 fixed on the dam body, to avoid sliding, on the other hand to intercept rainwater that penetrates into the soil at the top and bottom ends of the dam body, to avoid rainwater from penetrating into the inside of the dam body.

[0040] It should be noted that the waterproof inclined plate 11 can be a prefabricated concrete plate or other available materials, or it can be directly cast in sections on the dam body. The appropriate manufacturing method should be selected according to the conditions of the construction environment on site. For example, when the construction environment is complex and it is not convenient for large machinery to enter, it is preferred to use a prefabricated waterproof inclined plate 11 and then transport it to the construction site by a transfer machinery. When the construction environment is better, it is possible to choose to cast the waterproof inclined plate 11 in sections directly on the dam body.

[0041] Example 2

[0042] Optionally, by Figure 2As shown, in this embodiment, it also includes: an L-shaped water pumping pipe 2, a water outlet 14 is fixed on the waterproof inclined plate 11, one end of the L-shaped water pumping pipe 2 is connected to the water outlet 14, and the other end extends out of the dam body. The water outlet 14 can be fixed on one or several waterproof inclined plates 11. When the waterproof inclined plate 11 is installed, the L-shaped water pumping pipe 2 is connected. When the amount of water in the river channel is large, a pumping machine can be temporarily used to pump out the water in the river channel from the L-shaped water pumping pipe 2, and the pumped water can be used for municipal greening irrigation, etc.

[0043] In principle, water can also be pumped directly from the river channel, but the pumping machinery needs to be arranged at the top edge of the dam body, which is very close to the waterproof inclined plate 11, and there are certain safety hazards. It is safer to pump water through the L-shaped pumping pipe 2. The port of the L-shaped pumping pipe 2 can be designed at a position far away from the top edge of the dam body.

[0044] Preferably, by Figure 2 As shown, in the present embodiment, the top of the vertical portion of the L-shaped water pumping pipe 2 is higher than the top of the waterproof inclined plate 11, which can effectively prevent the water in the river channel from overflowing from the top of the vertical portion of the L-shaped water pumping pipe 2. In addition, by measuring the height of the water level in the L-shaped water pumping pipe 2, the water level in the river channel can also be known, that is, the distance between the water level in the river channel and the top of the dam body. There is no need to measure close to the river channel, which is safer.

[0045] Optionally, by Figure 2 As shown, in the present embodiment, the L-shaped water pumping pipe 2 comprises: a horizontal pipe 21, an elbow 22 and a vertical pipe 23. The horizontal pipe 21 is connected to the water outlet 14, the elbow 22 is connected to the horizontal pipe 21, the vertical pipe 23 is connected to the elbow 22, and the top of the vertical pipe 23 extends out of the dam body. In principle, the L-shaped water pumping pipe 2 can also be an integrated pipe. However, the L-shaped water pumping pipe 2 is composed of the horizontal pipe 21, the elbow 22 and the vertical pipe 23. The length and height of the L-shaped water pumping pipe 2 can be adjusted according to actual needs. When the L-shaped water pumping pipe 2 is damaged, the damaged part can also be replaced separately.

[0046] It should be noted that the horizontal pipe 21 , the elbow 22 and the vertical pipe 23 are all connected through flanges, and are fixedly connected to the water outlet 14 by means of flanges.

[0047] Example 3

[0048] Preferably, by Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, it also includes: reinforcing ribs 15, a plurality of reinforcing ribs 15 are fixed on the waterproof inclined plate 11 at equal intervals, and the length direction of the reinforcing ribs 15 extends along the horizontal direction. The reinforcing ribs 15 can greatly improve the structural strength of the waterproof inclined plate 11 and extend the service life of the waterproof inclined plate 11.

[0049] It is worth noting that the reinforcing ribs 15 can be designed to be integrally formed with the waterproof inclined plate 11, or prefabricated reinforcing ribs 15 can be used and fixed to the waterproof inclined plate 11 using conventional fixing means.

[0050] Preferably, by Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the cross-section of the reinforcing rib 15 is an obtuse triangle structure, and the outer side surface of the reinforcing rib 15 is a vertical surface, and the top surface of the reinforcing rib 15 is a downward inclined surface. The structural form of the reinforcing rib 15 can resist the impact of water flow and prevent the water flow from directly impacting the waterproof inclined plate 11. In addition, rainwater falling on the top of the reinforcing rib 15 will also flow out along the inclined surface.

[0051] When the staff needs to enter the river to test the water quality, the reinforcing ribs 15 can also be used as temporary steps.

[0052] Components not described in detail herein are prior art.

[0053] Working principle and use process of the utility model: When the waterproof structure of the utility model is used, firstly, grooves are dug at appropriate positions on the dam body to bury the upper water retaining plate 1121, the lower water retaining plate 1131 and the L-shaped water pumping pipe 2 respectively;

[0054] The waterproof inclined plate 11 is laid on the inclined surface of the dam body, and the upper water retaining plate 1121 and the lower water retaining plate 1131 are inserted into the soil foundation at the top and bottom of the dam body to reinforce the waterproof inclined plate 11, thereby ensuring the stability of the waterproof inclined plate 11 fixed on the dam body to prevent it from slipping. On the other hand, the rainwater that penetrates into the soil at the top and bottom of the dam body can be intercepted to prevent the rainwater from penetrating into the inner side of the dam body.

[0055] At this time, two adjacent C-shaped water guide frames 12 are butted together to form a water guide channel 121, and a waterproof membrane 13 is laid in the water guide channel 121. Rainwater that penetrates into the joint gap of the waterproof inclined plate 11 will enter the water guide channel 121 and flow out along the inclined surface of the water guide channel 121, thereby preventing rainwater from extending into the soil foundation of the dam body, thereby greatly improving the waterproof effect and safety.

[0056] When the amount of water in the river is large, a pumping machine can be temporarily used to pump out the water in the river from the L-shaped pumping pipe 2, and the pumped water can be used for irrigation of municipal greening, etc.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
