Abstract

The invention relates to a steel structure combined-type sandwich steel plate rock-fill dam, comprising a cushion layer region, a transition region, a rock fill region, a wave wall and a downstream slope protection. A water blocking panel, two side toe boards and a river bed toe board jointly form an impermeable structure, a combined-type sandwich steel plate of an upstream riverside surface of a dam body comprises an inner steel plate and an outer steel plate as well as a support skeleton, a plurality of fixed joint bars which are deeply inserted in the dam body are transversely arranged on the back surface of an inner single steel plate, and all the surfaces, the joint bars and butt joints or connecting bolts are all coated with a layer of antiseptic impermeable coating polyurea material. The rock-fill dam provided by the invention has the advantages of a gravity dam and a steel structure dam, is stable and is easy to construct, the structural form is flexible, the rock-fill dam can better adapt to topographic conditions, the performance requirement on damming material is low, multiple building materials can be used, environmental disruption produced by damming is reduced, and the rock-fill dam can be processed in batch in a factory, the site construction speed is fast, and the rock-fill dam is convenient to maintain or replace.

Description

[0001] technical field

[0002] The invention relates to a rockfill dam in the technical field of water conservancy, in particular to a steel structure combined sandwich steel plate rockfill dam. Background technique

[0003] The face rockfill dam is one of the common water retaining structures. It is a dam type composed of a rockfill body and a facing face. Its advantages are: the body of the dam is made of local materials (stone); the structure is simple; it is easy to heighten and expand; it has good adaptability to the foundation; However, the biggest disadvantage of this dam type is that the concrete slab is prone to temperature cracks during the construction process; and during the operation process, the uneven settlement of the dam body will also cause cracks, which will have an adverse effect on the stability of the dam body. And once there is a problem with the concrete panel, there are problems such as maintenance difficulties. Contents of the invention [0004...
