Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0022] as attached figure 1 and 2 As shown, a steel membrane face rockfill dam consists of a steel membrane face plate 2, a cushion layer area 3, a transition area 4, a main rockfill area 5, a secondary rockfill area 6, a toe plate 9, a wave wall 1, an anti-slip Steel bars 7, grouting curtains 8, and deformation induction grooves 10 are formed. The cushion zone 3 is followed by the transition zone 4, the main rockfill zone 5 and the secondary rockfill zone 6. The crest of the rockfill dam is equipped with a wave wall 1, which is a reinforced concrete structure. The bottom and both sides of the rockfill dam are provided with a toe plate 9, and a reinforced concrete structure is selected, and a curtain grouting 8 is provided at the front end of the rockfill dam bottom. The steel membrane panel 2 is laid on the upstream slope cushion area 3 of th...

Abstract

The invention discloses a steel membrane concrete faced rockfill dam which consists of a steel membrane concrete faces, a cushion layer zone, a transition zone, a main rockfill zone, a secondary rockfill zone, reinforced concrete toe boards, a wave prevention wall, anti-slip reinforcing steel bars, a grouting curtain and deformed inductive grooves, wherein the steel membrane concrete face is laid on the cushion layer zone of an upstream slope of a rockfill dam body; the top of the dam is provided with a reinforced concrete wave prevention wall; the bottom and the periphery of the dam body are provided with the reinforced concrete toe boards; the bottom at the front end of the dam body is provided with the curtain for grouting; the middle parts and the edges of the steel membrane faces are provided with groove-type deformed inductive grooves; the steel membrane faces on the top of the dam body extend into the reinforced concrete wave prevention wall; the bottom of the dam body and the steel membrane at the side part extend into the reinforced concrete toe boards; and the rear part of the steel membrane is provided with the anti-slip reinforcing steel bars. The steel membrane concrete faced rockfill dam provided by the invention has obvious advantages during the processes of construction, running, management and the like by adopting the steel membrane faces, and especially can well solve influences on faces by the deformation of rockfill materials of the dam body, so that the aspects of face crack resistance and seepage resistance as well as the dam body safety and the like are effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of rockfill dam engineering, and more specifically relates to a structural type of a face rockfill dam in the field of water conservancy engineering, which is a kind of structure in which a steel membrane face plate is closely combined with a rockfill material dam body to replace a traditional concrete face plate A new type of face rockfill dam. Background technique [0002] A rockfill dam is a type of dam that is supported by a rockfill body and uses soil, concrete, asphalt concrete and other materials as an anti-seepage body and water retaining structure. At present, concrete face rockfill dam is the most widely used type. The highest face rockfill dam built in my country is the Shuibuya Hydropower Station on the Qingjiang River in Hubei, with a dam height of 233m. Although the traditional concrete face rockfill dam type has been widely used at home and abroad, there are still some problems and defects i...
