Abstract

The utility model belongs to dam protection technical field, in particular to a novel dam slope protection block. The block comprises a block body, wherein symmetrical left concave-convex structures and right concave-convex structures are arranged on the upper part and lower part of the block body, the concave part and the convex part of the concave-convex structure are matched with each other in shape. The utility model adopts horizontal linkage lock, has high stability and very high storm brushing resistance and parallel dam flushing resistance; the block has regular and beautiful appearance, has small damage to environment and has the advantages of easy mechanical construction and easy construction quality control; the applicable range is wide; the novel dam slope protection block has the characteristics that side slope is ensured to be stable under water flow storm effect, and is flushing resistant; the novel dam slope protection block is convenient in construction, has neat and beautiful appearance and saves investment.

Description

Novel protecting slope of dam building block
(1) technical field
The utility model belongs to dykes and dams guard technology field, particularly a kind of novel protecting slope of dam building block.
(2) background technology
The safety of reservoir dam bank protection or river, lake bank protection work directly relates to the flood control safety of engineering, is the major issue of national economy, always is subjected to the great attention of government department.In the hydraulic engineering, particularly earth and rockfill dam reservoir upstream side slope revetment should be established special bank protection when requiring the surface, dam for materials such as soil, sand, sand gravels according to design specifications.Common bank protection form has enrockment, dry stone wall, stone masonry, prefabricated or cast-in-situ concrete etc., no matter adopt which kind of form, the technical technical security requirement that must satisfy the bump of wave scour, longitudinal dike current scour, floating thing and ice sheet and the extruding of freezing, freeze thawing resistance.Past, there was following shortcoming in dry stone wall, stone masonry bank protection commonly used: the source of (1) piece stone material is restricted, needs very big fund input especially in the plains region; (2) construction quality is not easy control; (3) presentation quality is poor.The crack appears in concrete revetment easily after the dam body sedimentation, must repair in case the crack produces, otherwise the dam body fine grained is taken away, dam slope unstability and then jeopardize dam safety.Therefore seek a kind of not only safety but also economic, and the bank protection form of easy construction, appearance looks elegant is very important.
(3) utility model content
The purpose of this utility model is to provide a kind of novel protecting slope of dam building block, realize large-scale river/channel face side slope revetment, reservoir earth and rockfill dam upstream side slope revetment near water, lake side slope revetment stable under wind wave action, antiscour, easy construction, construction quality control easily and outward appearance neat appearance, environmental protection.
The technical solution adopted in the utility model is as follows:
Novel protecting slope of dam building block comprises block body, and described upper part of body and bottom are equipped with the left concaveconvex structure and the right concaveconvex structure of symmetry, and the recess of described concaveconvex structure and protuberance shape are coincide.
Described recess is trapezoidal.
Also be provided with one or more perforates on the described body.
Described perforate is arranged at the body middle part.
The left and right sides of described body also is symmetrically arranged with lateral opening.
Percent opening on the body is 17-23%.
Novel protecting slope of dam building block provided by the utility model is owing to be provided with left and right sides concaveconvex structure, it is chain to form level in use, building block is up and down fixed by concaveconvex structure, very firm, storm resisting erosion well, weathering, freezing, floating thing threatens and other biological destroys, and have advantages such as easy construction, outward appearance neat appearance, environmental protection, and perforate can strengthen the bank protection drain function effectively in building block, greatly reduce the caused suction function of stormy waves, strengthen the stability of building block bank protection and reduce engineering quantity; Offer at the left and right sides of building block and lateral openingly both can obtain certain percent opening, be unlikely to again perforate is all focused on the anti-anti-ability of building block middle part influence, rationally distributed.The shape of perforate is unqualified in the building block, both can be circle, also can also can be other shapes for square.The wind and wave resistance best results of dykes and dams when the percent opening on the body is controlled between the 17-23%, concrete percent opening can be determined by the wind and wave resistance test.
This building block general using concrete casting forms.
The utility model has following advantage with respect to prior art:
(1) adopt horizontal interlocking, stability is high and have high wind and wave resistance scour and longitudinal dike scouring capability, is the desirable slope protection works measure of protection dam dam body or river, lake bank slope safety and stability.
(2) compare with traditional dry stone wall, stone masonry bank protection, concrete block profile rule is attractive in appearance, to environmental disruption little (avoiding exploiting in a large number mountain stone), have advantages such as the mechanized construction of being easy to, construction quality be easy to control.Simultaneously, concrete block also is better than cast in place concrete plate to the compliance of levee body distortion.
(3) applied widely, road, the large-scale river of particularly suitable (canal) is face side slope revetment, reservoir earth and rockfill dam upstream side slope revetment near water, lake side slope revetment and high slope revetment etc., have characteristics such as guaranteeing stable, the antiscour of side slope under the current wind wave action, easy construction, outward appearance neat appearance, saving investment.
(4) description of drawings
Fig. 1 is the structural representation of novel protecting slope of dam building block described in the embodiment.
Fig. 2 is the polylith slope protection block combination effect schematic diagram after building by laying bricks or stones.
(5) specific embodiment:
Below with specific embodiment the technical solution of the utility model is described, but protection domain of the present utility model is not limited thereto:
Embodiment 1
Referring to Fig. 1, novel protecting slope of dam building block comprises block body 1, and described upper part of body and bottom are equipped with the left concaveconvex structure 2 and the right concaveconvex structure 3 of symmetry, and the recess of described concaveconvex structure and protuberance shape are coincide.Described recess 4 is trapezoidal.Also be provided with a plurality of perforates 5 on the described body, perforate 5 is arranged at the body middle part.The left and right sides of described body also is symmetrically arranged with lateral opening 6.
Build by laying bricks or stones by order layering from bottom to top in the building block construction, the effect schematic diagram after building by laying bricks or stones is referring to Fig. 2.

Claims (6)
