Problems solved by technology
[0004] However, in actual construction, cement will generate a large amount of hydration heat during the setting process of concrete. This heat is wrapped in the interior of the concrete structure and does not need to be lost quickly. On the one hand, the extremely rising temperature makes the temperature difference between the concrete and the external environment larger and larger. Under the cross action of these two effects, temperature cracks will appear on the surface of the concrete structure, which will lead to water seepage in the dam

Embodiment
[0041] Embodiment: a kind of anti-seepage hydraulic engineering dam, such as figure 1 with Figure 4 As shown, it includes a dam body 1 and several water delivery pipes 13 that are parallel to each other and buried in the dam body 1. The dam body 1 is formed by pouring concrete, and the water delivery pipe 13 is parallel to the length direction of the dam body 1. Two adjacent water delivery pipes 13 are connected with a number of water pipes 131 spaced along its length direction, so that each water pipe 13 is connected to each other, and each water pipe 13 is vertically connected with a number of steel pipes 11 distributed along the length direction of the water pipe 13. Each steel pipe 11 All pass through the dam body 1 upwards, and one end that passes through is flush with the end face of the dam body 1 . Each steel pipe 11 is provided with a number of drainage holes 12 , and each steel pipe 11 is provided with a number of cooling fins 111 on the side wall.

The invention relates to an anti-seepage water conservancy project dam, which is applied in the technical field of anti-seepage of dams. It includes a dam body and several rows of steel pipes buried vertically in the dam body. They are all connected by water pipes. There are water pipes connected between two adjacent water pipes. One of the water pipes is connected with a number of water inlet pipes extending out of the dam body. Each water inlet pipe is connected to a submersible pump through a rubber tube; each row of steel pipes A number of section steels distributed in the height direction of steel pipes are welded, and the ends of each layer of section steel are connected by beams, and vertical beams are connected between two adjacent section steels. The invention has the effect of reducing water seepage of the dam body.
Description
technical field [0001] The invention relates to the technical field of anti-seepage of dams, in particular to an anti-seepage hydraulic engineering dam. Background technique [0002] Dams refer to buildings and structures that are waterproof and water-retaining. At present, there are two main types of dams: earth-rock dams and concrete dams, which have very powerful functions and can store or retain water. The stability and reliability of hydraulic projects are related to The construction of the dam is closely related, so we must pay attention to the construction of the dam to ensure the smooth progress of the dam construction and improve the safety of the dam. [0003] The Chinese patent with the notification number CN209178938U discloses a concrete dam reinforcement structure, including concrete dam surface, planting reinforcement holes, planting reinforcement, integral reinforcement frame, dam surface plus high-rise, dam surface crack defects, excavation of stereotyped gr...
