Description

Technical Field

[0001] The utility model belongs to the technical field of gravity dams, and in particular relates to a water stop structure of a concrete gravity dam. Background Art

[0002] A gravity dam is a dam built of concrete or stone, which mainly relies on the deadweight of the dam body to maintain its stability. According to its structural form, it can be divided into solid gravity dam, hollow gravity dam and wide-slot gravity dam; according to the overflow situation, it can be divided into non-overflow gravity dam and overflow gravity dam; according to the dam construction material, it can be divided into concrete gravity dam and mortar-stone gravity dam.

[0003] Gravity dams mainly rely on the anti-sliding force generated by the deadweight of the dam body to meet their own stability requirements. At the same time, the compressive stress generated by the deadweight of the dam body can be used to offset the tensile stress caused by water pressure. The basic cross-section of a gravity dam is a triangle. In the plane, the axis of the dam is usually a straight line. Sometimes, in order to adapt to the terrain and geological conditions, or to meet the requirements of the hub layout, it can also be arranged as a broken line or an arch with a small curvature arching upstream.

[0004] Chinese Patent: Publication (Announcement) No.: CN217758596U, discloses a waterstop structure suitable for roller compacted concrete gravity dams, and the utility model has the following beneficial effects: the utility model includes first, second and third waterstop grooves; the first waterstop is arranged at the upstream edge of the dam body joint, and its bottom extends into the first waterstop groove; the first branch waterstop has a first horizontal section; the second waterstop is arranged in parallel with the first waterstop and is located on its downstream side; the second branch waterstop has a second horizontal section; the third waterstop is arranged at the downstream edge of the dam body joint, and its bottom extends into the third waterstop groove; the fourth waterstop is arranged on the foundation surface on the upstream side of the dam body along the dam axis direction, and the end is connected to the first waterstop; wherein the first horizontal section is connected to the second waterstop, and the second water section is located above the first horizontal section. The utility model effectively prevents water from entering the dam body through the gap between the joint / foundation surface, thereby realizing all-round anti-seepage protection for the dam body;

[0005] In addition, the water-stop structure can effectively prevent water from flowing into the interior of the dam through the gaps, thereby achieving all-round anti-seepage protection for the dam body. However, while stopping the water, the water flow will generate a large amount of impact force due to the cut-off, and these impact forces will directly act on the surface of the water-stop structure. Long-term impact will cause damage to the water-stop structure. Utility Model Content
