Abstract
The utility model discloses an anti-impact structure used for an earth-rock cofferdam. The anti-impact structure is suitable for the earth-rock cofferdam of a river channel with high flow and high flow velocity. The anti-impact structure comprises a cofferdam body and further comprises an anti-impact structure body which is composed of steel bar gabion strings. The steel bar gabion strings are piled to be step-shaped and arranged on the upstream face of the cofferdam body. Due to the fact that the steel bar gabion strings are adopted, the anti-impact structure formed on the upstream face of the cofferdam body can effectively protect the upstream face of the earth rock cofferdam under the impact of water flow, the situation that defects are generated on the upstream face under the effect of the water flow is avoided and stability of the whole earth rock cofferdam is guaranteed. The steel bar gabion strings are mutually connected, therefore, the integral step-shaped anti-impact structure is formed and the protection is firmer.
Description
Technical field
The utility model relates to a kind of erosion control structure for earth rock cofferdam.
Background technology
In Hydraulic and Hydro-Power Engineering is built, the general earth rock cofferdam that adopts ensures the dam dry work, yet in big flow high flow rate river course, current are comparatively rapid, this will cause severe impact to the upstream face of earth rock cofferdam, make the upstream face of earth rock cofferdam form defective, the structure of whole earth rock cofferdam is threatened, even the cofferdam of destroying by rush of water.
The utility model content
Technical problem to be solved in the utility model provides a kind of erosion control structure that is used for earth rock cofferdam that is applicable to big flow high flow rate river course.
The erosion control structure that is used for earth rock cofferdam that its technical problem that solves the utility model adopts comprises the cofferdam body, also comprises the erosion control structure that is made of the reinforced gabion string, and described reinforced gabion string is piled into step-like and is arranged on the upstream face of described cofferdam body.
Further be that the reinforced gabion string of adjacent two-stage step interconnects.
Further be, described reinforced gabion string is made up of cage of reinforcement and the material that rockfills, and the described material that rockfills is seated in the described cage of reinforcement.
Further be that described cage of reinforcement is rectangular-shaped.
Further be, described cage of reinforcement is made up of main framing reinforcing bar and steel grid, and described main framing reinforcing bar constitutes the seamed edge of described cuboid cage of reinforcement, thereby described steel grid is installed in the surface that constitutes described cuboid cage of reinforcement on the main framing reinforcing bar.
The beneficial effects of the utility model are: owing to adopted the reinforced gabion string; thereby the erosion control structure that can form at the upstream face of cofferdam body; like this under the impact of current; the erosion control structure can effectively be protected the upstream face of earth rock cofferdam; avoid upstream face under the effect of current, to form defective, ensured the firm of whole earth rock cofferdam.Interconnect between the reinforced gabion string, form the step erosion control structure of an integral body like this, make that protection is more firm.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1;
Fig. 3 is the schematic diagram of cage of reinforcement;
Component, position and numbering among the figure: cofferdam body 1, erosion control structure 2, reinforced gabion string 3, cage of reinforcement 4, main framing reinforcing bar 5, steel grid 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises cofferdam body 1, also comprises the erosion control structure 2 that is made of reinforced gabion string 3, and described reinforced gabion string 3 is piled into step-like and is arranged on the upstream face of described cofferdam body 1.Reinforced gabion string 3 is made up of cage of reinforcement 4 and the material that rockfills, and the described material that rockfills is seated in the described cage of reinforcement 4.Cage of reinforcement 4 with rockfill the material materials than determining according to concrete flow and flow velocity, to reduce overall cost.When being subjected to water impact, the erosion control structure 2 that reinforced gabion string 3 forms can effectively be resisted the impact of current, the protection upstream face.
In order to increase the bulk strength of erosion control structure 2, as shown in Figure 2, the reinforced gabion string 3 of adjacent two-stage step interconnects.Reinforced gabion string 3 interconnects the back and forms an integral body, and its impact resistance is stronger.Can adopt iron wire or reinforcing bar to connect between the reinforced gabion string 3, also can adopt the mode of welding.
Concrete, as shown in Figure 3, described cage of reinforcement 4 is the cuboid body.Described cage of reinforcement 4 is made up of main framing reinforcing bar 5 and steel grid 6, and described main framing reinforcing bar 5 constitutes the seamed edge of described cuboid cage of reinforcement 4, thereby described steel grid 6 is installed in the surface that constitutes described cuboid cage of reinforcement 4 on the main framing reinforcing bar 5.
Embodiment
At cofferdam body 1 upstream face, at first to reserve erosion control structure 2 positions; Second step was made reinforced gabion string 3 in processing factory or relevant place, single reinforced gabion string 3 is of a size of 2～3 meters * 1～2 meter * 1～2 meter (length * wide * height) and satisfies lifting requirements, 20～25 millimeters of main framing reinforcing bar 5 diameters, 1.0～1.5 meters of spacings, 6.5～10 millimeters of steel grid 6 diameters, between 15～20 centimetres of array pitch, the stone particle diameters of filling must not be less than 250mm in the cage of reinforcement 4; The 3rd step lifted reinforced gabion string 3 to earth rock cofferdam body 2, and was piled into step-likely, and reinforced gabion string 3 is used iron wire, reinforcing bars or is welded to connect into wholely, and tie point or pad must not form the erosion control structure 2 that is made of reinforced gabion string 3 less than 3 places.
