Abstract
A kind of new earth and rockfill dam upstream dam slope wave resistance percussion mechanism is the utility model is related to, belongs to hydraulic engineering field.The utility model includes compound polyurethane material roller, stainless steel tube, nylon rope, rope lengths adjustment axis, earth and rockfill dam, bulwark；By stainless steel tube by the equidistant connection of compound polyurethane material roller, make an erosion control row, erosion control is arranged with nylon rope and is connected, and it is fixed in the rope lengths adjustment axis on earth and rockfill dam, when the spray produced in reservoir comes towards dam impact, arranged just past wave resistance, which reduces most of energy.The problem of the utility model is solved in the larger reservoir of stormy waves, and wave easily produces impact failure to dam upstream dam slope, at the same can also reduce upstream dam slope because other floating materials, ice sheet impact and caused by leak aggravation, or even the danger of dam break.There is more preferable practicality.
Description
Technical field
A kind of new earth and rockfill dam upstream dam slope wave resistance percussion mechanism is the utility model is related to, belongs to hydraulic engineering field.
Background technology
Earth and rockfill dam mainly has the dam that the local materials such as soil, building stones fill, and is a kind of history dam type the longest,
And it is most widely used in world's dam and a kind of dam type with fastest developing speed.And bank protection is the important set of earth and rockfill dam external structure
Into part, its main function is to protect dam body from wave scour, endanger along slope current scour, floating material, and prevent dam
Body is subject to rainwater, strong wind, the stormy waves at tail water position, ice sheet and the infringement of current and the destruction of the dry and cracked factor of animal, frost heave.
So in order to protect the safety of dam, it is necessary to take safeguard measure to bank protection, it is impossible to because bank protection damage and caused by dam break risk.
The content of the invention
The utility model provides a kind of new earth and rockfill dam upstream dam slope wave resistance percussion mechanism, solves larger in stormy waves
Reservoir in, the problem of wave easily produces impact failure to dam upstream dam slope, while can also reduce upstream dam slope because of other
Floating material, ice sheet impact and caused by leak aggravation, or even the danger of dam break.
The technical solution of the utility model is：A kind of new earth and rockfill dam upstream dam slope wave resistance percussion mechanism, including poly- ammonia
Ester Composite material roller 1, stainless steel tube 2, nylon rope 3, bulwark 4, earth and rockfill dam 5, rope lengths adjustment axis 6；
The compound polyurethane material roller 1 is equidistant to be installed on stainless steel tube 2 and is distributed in array, is formed anti-
Wave row；Wave resistance row is connected by nylon rope 3 with the rope lengths adjustment axis 6 on earth and rockfill dam 5, and rope lengths adjustment axis 6 is used to control
The length of nylon rope 3 processed, bulwark 4 are located on earth and rockfill dam 5.
The wave resistance row includes three groups, and every group includes five rows, and often row is equipped with three compound polyurethane material rollers 1.
The length of the nylon rope 3 in water is determined according to the height difference between design water level and normal pool level.
The operation principle of the utility model is：When the water wave in reservoir is by by compound polyurethane material roller 1 and not
During the wave resistance row that the steel pipe 2 that becomes rusty forms, the thrust of wave rolls the compound polyurethane material roller 1 of first row；When wave reaches
When second row, energy is reduced, and at this moment complementary energy makes second row compound polyurethane material roller 1；Finally reach bank protection
Energy is almost depleted, substantially reduces and bank protection is washed away.
The beneficial effects of the utility model are：It is simple in structure, it is easily operated, it is larger suitable for stormy waves, floater in river compared with
The more area of more and long-term ice sheet.Solve in the larger reservoir of stormy waves, wave easily produces dam upstream dam slope
The problem of impact failure, at the same can also reduce upstream dam slope because other floating materials, ice sheet impact and caused by leak aggravation, very
To the danger of dam break.

Embodiment
With reference to the accompanying drawings and detailed description, the utility model is further described.
Embodiment 1：As shown in Figure 1, 2, a kind of new earth and rockfill dam upstream dam slope wave resistance percussion mechanism, including polyurethane are answered
Condensation material roller 1, stainless steel tube 2, nylon rope 3, bulwark 4, earth and rockfill dam 5, rope lengths adjustment axis 6；
The compound polyurethane material roller 1 is equidistant to be installed on stainless steel tube 2 and is distributed in array, is formed anti-
Wave row；Wave resistance row is connected by nylon rope 3 with the rope lengths adjustment axis 6 on earth and rockfill dam 5, and rope lengths adjustment axis 6 is used to control
The length of nylon rope 3 processed, bulwark 4 are located on earth and rockfill dam 5.Just passed through when the wave in reservoir comes towards upstream dam slope impact
Wave resistance row is crossed, reduces most of Wave energy.
The wave resistance row includes three groups, and every group includes five rows, and often row is equipped with three compound polyurethane material rollers 1, prevents
Wave row specifically organizes number, number of rows and often the quantity of the upper compound polyurethane material roller 1 of row is voluntarily determined according to actual river width.
The length of the nylon rope 3 in water is determined according to the height difference between design water level and normal pool level, is prevented
Water level decreasing and 3 length of nylon rope is inadequate, cause wave resistance row it is stranded on dam slope.
The rope lengths adjustment axis 6 is the length for the manual adjustment nylon rope 3 when SEA LEVEL VARIATION is king-sized
Degree, prevents that wave resistance row is stranded.
1 material of roller is because the material is good, mechanical with resistance to biological aging, wear-resisting property using compound polyurethane material
The series of advantages such as intensity is big, good weatherability, oil resistivity are good, and it is moderate, thus it is more durable, it is hardly damaged.
Specific embodiment of the present utility model is explained in detail above in conjunction with attached drawing, but the utility model is not
It is limited to the above embodiment, within the knowledge of a person skilled in the art, this practicality can also be not being departed from
Various changes can be made on the premise of new objective.
