Problems solved by technology

However, the natural terrain conditions vary widely, and the geological conditions on both sides of the strait are different from time to time. It is difficult to meet the needs of the actual situation only by relying on the linear layout of the face dam.

Embodiment Construction

[0021] like figure 1 As shown, the broken line concrete face rockfill dam in this embodiment has a dam axis 1 and a reinforced concrete face plate 2. The characteristic of this example is that the dam axis 1 is a broken line, and the face 2 built along the dam axis also forms a broken line. The turning point of the two panels is transitionally connected by a connecting plate 3 of reinforced concrete structure, a plinth 4 of reinforced concrete structure is arranged downstream of the panels, and a cushion layer 5, a transition layer 6 and a rockfill body 15 are arranged under the panels.

[0022] The thickness of the panel 2 is: the top is 0.3m, and the bottom varies with the height according to the calculation formula d=0.3+0.0035H, wherein, H is the vertical distance from the calculated section to the top of the panel, and the unit is m.

[0023] The connecting plate 3 is set at the turning point of the panel, and the connecting plate and the two side panels are arranged acco...

Abstract

The invention relates to a broken line type concrete face rock-fill dam and a method for constructing the same. The technical problem resolved by the invention is to provide a face rock-fill dam and a method for constructing the same, by which the dam body can be designed in accordance with topographic and geologic conditions on site so as to lower the engineering risk, save the engineering cost and widen the adaptive condition of the dam type of the rock-fill dam for different topographic and geologic conditions. The technical proposal resolving the problem is as follows: the broken line type concrete face rock-fill dam comprises a dam axis and faceplates with reinforced concrete structures; the rock-fill dam is characterized in that the dam axis is of the broken line, and faceplates built along the dam axis also form a shape of a broken line, and turning parts of two faceplates are in transitional connection by a connecting plate with a reinforced concrete structure, and peripheries of faceplates are provided with toe boards, and a cushion course, a transitional layer and the rock-fill body are arranged below the faceplates. The broken line type concrete face rock-fill dam and the method can be applied to a reinforced concrete face dam project which can not be in straight-line type arrangement along the direction vertical to the river due to specially topographic and geologic conditions.

Description

technical field [0001] The invention relates to a broken line concrete face rockfill dam and a construction method thereof. It is suitable for reinforced concrete face rockfill dam projects that cannot be arranged in a straight line perpendicular to the direction of the river due to special terrain and geological conditions. Background technique [0002] When the barrage adopts a reinforced concrete face rockfill dam, a linear face dam arranged vertically to the flow direction of the river or slightly oblique to the flow direction of the river is often used. Also, ensure that the face dam plinth sits on a valid foundation. However, the natural topographical conditions vary widely, and the geological conditions on both sides of the strait are sometimes different. It is difficult to meet the needs of the actual situation only by relying on the linear layout of the face dam. [0003] With the rapid development of rolling rockfill technology in recent years, the settlement of ...
