Embodiment 1

[0036] Embodiment one: see figure 1 — Figure 4 , Figure 7 , a steel structure combined sandwich steel plate rockfill dam, the dam body is a rockfill dam composed of rockfill, the rockfill dam includes cushion area, transition area, rockfill area (main rockfill area and secondary rockfill area Area), the anti-seepage structure composed of steel structure panels, toe slabs on both banks and riverbed toe slabs, as well as the wave wall at the top of the dam and downstream slope protection, and the upstream facing surface of the dam body is set as a combined sandwich steel plate.

[0037] The combined sandwich steel plate includes an inner layer combined steel plate and an outer layer combined steel plate, and a supporting frame is arranged between the inner and outer layer combined steel plates.

[0038] The inner composite steel plate is attached to the water facing surface of the dam body. The inner steel plate is a plurality of weather-resistant steel sheets that meet the ...

Embodiment 2

[0044] Embodiment two: see Figure 5 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the I-shaped steel is formed by two channel steels fixed by bolts or welding.

Embodiment 3

[0045] Embodiment three: see Figure 6 , the content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that fixed bolts are vertically fixed on the outer surface of the inner single-piece steel plate, and the lower flange of the I-shaped steel is provided with a through hole for use. , there is a layer of sealing sheet between the I-shaped steel and the inner single-piece steel plate, and the through hole is matched and set on the corresponding fixed bolt, and the end of each fixed bolt is fixed with a nut; the upper flange of the I-shaped steel is vertical Fixing bolts are fixed, the outer single-layer steel plate is provided with opposite through holes, and a layer of sealing sheet is placed between the outer single-layer steel plate and the I-shaped steel. And the through hole is set on the corresponding fixed bolt, and the end of each fixed bolt is fixed with a nut.

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...
