Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] Such as figure 1 with figure 2 As shown, the present invention includes a stay cable 1 , the direction of the stay cable 1 is parallel to the direction of the river, one end of which is connected to the foundation 4 , and the other end is connected to the column 3 . Water retaining panels 2 are overlapped between two adjacent columns 3 . Drive into some anchor rods 5 in the surrounding rock mass of foundation 4, and the anchor rod head will expose certain length, is used for being connected with foundation.

[0017] Water-retaining panel 2 can be made of high-strength waterproof materials such as steel structure, reinforced concrete, asphalt concrete.

[0018] The connection between the water retaining panel 2 and the column 3 is provided with a water stop. In the direction of the dam axis, the dam can be simplified as a multi-span simply supported beam model fo...

Abstract

The invention discloses a dam comprising cables, uprights, water baffles, a foundation, anchor rods and an anti-seepage curtain. One ends of the cables are connected to the uprights, and the other ends of the cables are connected to the foundation located in front of the dam; the multiple anchor rods are driven into a surrounding rock mass making contact with the foundation to firmly connect the foundation with the surrounding rock mass; the foundation is in a strip shape in the river direction and has a certain width and length, and the foundation is arranged in front of the dam to provide tension for the cables; the uprights are built in the corresponding positions of the foundation, and the foundation and the uprights are connected by the cables; and each water baffle is arranged between the corresponding two adjacent uprights. The technology of cable-stayed bridges is applied to the dam construction technology, and thus the high and thin dam is provided. According to the dam, the cables are arranged in front of the dam so that the strength of materials can be given to full play. Meanwhile, the dam has the characteristics that the uplift pressure of the bottom of the dam is small, the dam can adapt to various topographical and geological conditions, the concrete consumption of a dam body is reduced, the construction period is shortened, template erecting is easy, the temperature stress is small, and independent action of dam sections is achieved.

Description

technical field [0001] The invention relates to a water-retaining dam, in particular to a dam in which a cable is arranged in front of the dam to bear the tension to prevent the dam from tipping backwards under the action of water pressure, and belongs to the technical fields of water conservancy engineering and civil engineering. Background technique [0002] At present, the dams in the world are developing in a higher and thinner direction: there is a 185-meter-high concrete gravity dam Three Gorges Dam, a 305-meter-high concrete arch dam Jinping Class I Dam, and a 304-meter-high dam. Earth-rock dam Nurek Dam. It can be said that the highest dam has just reached the level of 300 meters, and each dam type has its own shortcomings, such as the temperature of the concrete gravity dam is not easy to control during the construction process, and the strength of the dam body material cannot be fully exerted; The dam has high requirements on the topography and complex formwork; t...
