Problems solved by technology

[0002] The anti-seepage body of the traditional pier-type concrete face dam is composed of the face plate and the toe-slab. Both the face plate and the toe-slab are made of concrete. During the construction process of the concrete, due to the existence of hydration heat, the face plate is prone to temperature cracks. The existence of cracks will lead to water seepage in the dam body, causing penetration and stability problems in the overall structure. At the same time, once the large-area concrete panels are damaged, maintenance and repair are very inconvenient

Embodiment 1

[0035] Embodiment one: see figure 1 , figure 2 , Figure 4 , Figure 6-Figure 8 , a steel structure hollow composite dam in the figure, which contains a certain number of concrete buttresses, concrete caps below the buttresses, and steel structure composite panels above the buttresses, and a cut-off wall is arranged under the concrete caps, said The cross-section of the steel structure composite panel matches the cross-section of the pier, and is covered on the top and both sides of the pier; the steel structure composite panel contains an internal skeleton and several unit steel plates covering the two surfaces of the skeleton. The splicing gap between the unit steel plates is located at the frame, the edges of the unit steel plates are connected to the frame by fasteners, and the joints between adjacent unit steel plates are provided with sealing structures.

[0036] The skeleton includes vertical beams and cross beams that intersect vertically and horizontally. Both the...

Embodiment 2

[0040] Embodiment two: see figure 1 , image 3 , Figure 4 , Figure 6-Figure 8 , embodiment two is basically the same as embodiment one, and the similarities will not be repeated. The difference is that the lower edge of the steel structure composite panel is embedded in a section of the river bed plinth (such as figure 2 shown in ), and is provided with a sealing structure; the edge of the steel structure composite panel at both ends of the dam body is embedded in a section of the toe plate of the river channel, and is provided with a sealing structure.

Embodiment 3

[0041] Embodiment three: see figure 1 , figure 2 , Figure 5 , Figure 6-Figure 8 , Embodiment 3 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the sealing structure includes a cross-section approximately "Ω"-shaped sealing strip, and the two lower edges of the lower part of the sealing strip are respectively press-fitted. It is between the unit steel plate and the surface of the frame, and is fixed by the fastener; the upper part of the sealing strip is a cap structure, and the cap structure covers the joints of the adjacent unit steel plates.

Abstract

The invention discloses a steel structure open web combined dam. The steel structure open web combined dam comprises a certain number of concrete buttresses, a concrete bearing platform below the buttresses, and a steel structure panel on the buttresses; a seepage-proofing wall is arranged below the concrete bearing platform; the cross section of the steel structure combined panel is matched withthat of each buttress, and is wrapped on the buttresses and two sides of the buttresses; the steel structure combined panel comprises an internal framework and a plurality of unit steel plates which are wrapped on two surfaces of the framework; a splicing gap between adjacent unit steel plates is positioned at the framework; the edges of the unit steel plates are connected to the framework through a fastening piece; and a sealing structure is arranged at the splicing gap between adjacent unit steel plates. In the dam, the steel structure panel is adopted, seepage-proofing capacity is improved, construction is simplified and cost is reduced, and the dam is favorable for environment-friendliness.

Description

technical field [0001] The invention relates to the technical field of water conservancy infrastructure, in particular to a steel structure hollow composite dam. Background technique [0002] The anti-seepage body of the traditional pier-type concrete face dam is composed of the face plate and the toe-slab. Both the face plate and the toe-slab are made of concrete. During the construction process of the concrete, due to the existence of hydration heat, the face plate is prone to temperature cracks. The existence of cracks will lead to water seepage in the dam body, causing penetration and stability problems in the overall structure. At the same time, once the large-area concrete panels are damaged, maintenance and repair are very inconvenient. Contents of the invention [0003] The object of the present invention is to provide a steel structure hollow composite dam in order to solve the above problems. [0004] The technical scheme of the present invention is: a steel str...
