Abstract
The utility model provides a concrete dam backward slope afforestation structure. Concrete dam back slope greening structure is including laying reinforcing bar net on the slope of concrete dam, along the concrete beam of slope horizontal direction extension and reinforcing bar net and concrete beam upper surface cover have the surface soil of grass seed, the concrete beam is crisscross net roof beam on the slope, the concrete beam passes the reinforcing bar net. Compared with the prior art, the utility model provides an its simple structure of concrete dam backward slope afforestation structure is guaranteeing to afforest on the surface soil under the stable prerequisite of bank protection, and the environmental protection is practical, is particularly useful for the dam body construction in the scenic spot.
Description
Technical Field
The utility model belongs to the technical field of the dam body bank protection technique and specifically relates to a concrete dam back slope greening structure is related to.
Background
The concrete dam is a dam formed by pouring (or rolling) concrete or assembling precast concrete blocks, and is a common dam type. Generally classified as gravity dams, large end dams, and arch dams. The concrete dam can discharge flow from the dam body, and the structure of the concrete dam is divided into a non-overflow dam section, an overflow dam section and the like according to whether the concrete dam participates in the flow discharge or not.
For a non-overflow dam section, a concrete dam slope is directly arranged at the downstream by adopting a slope ratio of 1: 0.7-1: 0.8, relevant greening measures are not adopted, and for buildings in scenic spots, the mode is not coordinated with local landscapes.
Therefore, it is desirable to provide a greening structure for the back slope of a concrete dam to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a concrete dam backward slope afforestation structure, this dam slope have pleasing to the eye concurrently under the stable prerequisite of original dam body not influencing, are particularly useful for as the bank protection in the scenic spot, and the environmental protection is practical.
The technical scheme of the utility model is that: the utility model provides a concrete dam bank back slope greening structure, including lay reinforcing bar net on the slope of concrete dam, along the concrete beam of slope horizontal direction extension and be in reinforcing bar net and concrete beam upper surface cover have the surface soil of grass seed, the concrete beam is crisscross net roof beam on the slope, the concrete beam passes the reinforcing bar net.
The supporting and greening work of the reinforced concrete beam can be carried out simultaneously with the rising of the filling height of the dam body, and can also be carried out after the filling of the dam body is finished.
Preferably, the concrete beam is a diamond-shaped grid beam.
Preferably, the height of the concrete beam is 350 mm-450 mm, and the wall thickness of the beam is 200 mm-300 mm.
Preferably, the distance between every two adjacent grids of the concrete beam is 1-4 m.
Preferably, the thickness of the top soil is not more than 1 m.
Compared with the prior art, the beneficial effects of the utility model are that: simple structure, under the stable prerequisite of guaranteeing the bank protection, afforest on the topsoil, the environmental protection is practical, is particularly useful for the dam body construction in the scenic spot.
Drawings
Fig. 1 is a schematic cross-sectional structural view of a greening structure of a back slope of a concrete dam provided by the present invention;
fig. 2 is a sectional view taken along a-a of fig. 1.
In the attached drawing, 1-concrete dam, 2-reinforced concrete beam, 3-reinforcing mesh, 4-surface soil and 5-grass seed.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" used herein refer to the directions of the drawings, and do not limit the structure of the drawings.
As shown in fig. 1 and 2, the utility model provides a concrete dam back slope greening structure includes the reinforcing bar net 3 laid on the slope of concrete dam 1, the concrete beam 2 extending along the horizontal direction of the slope, and the surface soil 4 with grass seeds 5 covered on the reinforcing bar net 3 and the concrete beam 2.
The concrete beam 2 is a staggered rhombic grid beam on the slope, the height of the beam is 350 mm-450 mm, and the wall thickness of the beam is 200 mm-300 mm. The space between every two adjacent grids of the concrete beam 2 (namely the hollow size of a diamond) is 1 m-4 m, and the steeper the dam slope is, the smaller the space is.
In order to facilitate the soil laying on the slope, a reinforcing mesh 3 is laid on the slope, and the concrete beam 2 penetrates through the reinforcing mesh 3.
And (3) after soil is paved on the upper surfaces of the reinforcing mesh and the reinforced concrete beam, sowing grass seeds on the surface soil, and maintaining, wherein the thickness of the surface soil is not more than 1 m.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
