The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a dam face anti-overflow dam structure of a concrete faced rockfill dam, which comprises a rockfill dam body, wherein the top of the rockfill dam body is the rockfill dam face,
the rockfill dam face is provided with a first groove, and the first groove is a strip-shaped groove along the trend of a river channel;
color strip cloth is laid on the rockfill dam face, and the color strip cloth is laid on the first groove and the rockfill dam faces on the two sides of the first groove;
a plurality of grit weights have been placed to various strip cloth upper surface, the grit weight is located the left and right sides of first slot.
A second groove is arranged on the rockfill dam face in parallel with the first groove, the second groove is positioned on one side, close to the river channel, of the first groove, the side edge, close to the river channel, of the color stripe cloth is positioned in the second groove, and the other side of the color stripe cloth extends to the rockfill dam face, far away from the river channel, outside the first groove;
the bottom surface of the second groove is arc-shaped, soil is paved above the color stripe cloth in the second groove, and the second groove is filled with the soil so that the top of the second groove and the rockfill dam face are a plane.
The sand and stone weight is a small willow stone pillow which is placed on the color stripe cloth between the first groove and the second groove, and the small willow stone pillow is also placed on the color stripe cloth between the first groove and one end, far away from a river channel, of the rockfill dam surface;
the small willow stone pillows are distributed in parallel with the first grooves, and a distance is reserved between every two adjacent small willow stone pillows.
The mass of the small-sized willow stone pillow is 10-20 kg.
The lower surface of the color stripe cloth is tightly adhered to the first groove, the second groove and the rock-fill dam surface for laying.
The first groove is positioned on one side of the rockfill dam face far away from the river channel and is parallel to the edge of the side of the rockfill dam face.
Firstly, a first groove is dug at the position, far away from a river channel, of the dam surface by an excavator, manual finishing is smooth, then color strip cloth is laid in the first groove, and the color strip cloth is laid from the upstream to the downstream along the groove and directly laid outside the dam. Digging a smaller second groove at the first groove and one side close to the river channel, paving one side of the color stripe cloth in the second groove, paving soil to fill the second groove, paving the other side of the color stripe cloth on the dam surface at one end far away from the river channel, pressing the color stripe cloth at the two sides of the first groove by using a small-sized willow stone pillow, and if overproof flood is encountered, water can be discharged outside the dam along the groove paved with the color stripe cloth, so that the dam body is prevented from being washed away, and if the water flow is large, the grooves can be increased. And after rainstorm, the excavator cuts the two sides of the first groove into down slopes, and backfilling and rolling are carried out.
The beneficial effect of this scheme can learn according to the statement to above-mentioned scheme, simple structure, and reasonable in design can prevent effectively that unfinished panel rock-fill dam from being destroyed by the dam flood, and the construction is simple, and the material input is few, and construction cost is low. The dam face overflow prevention dam structure of the concrete faced rockfill dam solves the flood fighting problem of the concrete faced rockfill dam during rockfill filling construction, water overflowing the rockfill dam body is discharged outside the dam along the first grooves paved with the color strip cloth, erosion of the dam body is avoided, and the color strip cloth can prevent sand and stone from being taken away by erosion of water flow to the dam body and damage the unfinished dam body. In order to avoid that water flow can still damage the dam body when penetrating between the rockfill dam face and the color stripe cloth, the second groove is designed, one side of the color stripe cloth is placed in the second groove and pressed by soil, and water can be prevented from penetrating into the lower side of the color stripe cloth. The small willow stone pillow is used for pressing the color stripe cloth, so that the color stripe cloth is not washed away by water or blown away by wind, and the small willow stone pillow is stable enough and can also resist over-high flow speed or over-high water quantity of water flow. Enough gaps are reserved between the small willow stone pillows, so that water flow can reach the first grooves through the small willow stone pillows, and the dam body is not damaged due to accumulated water instead of blockage of the water flow.
