Technical Field
The utility model belongs to the field of hydraulic engineering and road traffic, and particularly relates to a permeable embankment and water retaining weir combined structure.
Background
At present, a water retaining weir is often used for river landscape water storage, in order to meet the communication of water surfaces at the upstream and the downstream of a weir body, weir crest overflow is generally adopted, and a water passing road surface is arranged at the weir crest with traffic requirements; or adopt the bridge structure, satisfy surface of water intercommunication and traffic function simultaneously. The prior art has the problems that: the water passing through the road surface obstructs traffic when overflowing, and the durability of the road surface structure is poor; when setting up the bridge and culvert, the bridge cost is higher, and the culvert discharge is on the small side, and the bridge and culvert need set up special basis in addition, and is high to weir body bearing capacity requirement, construction cycle length. Therefore, it is necessary to adopt a new structure to solve the above problems.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems existing in the existing structural form, the utility model provides a structure combining a water permeable embankment and a water retaining weir, which can meet the requirements of water storage and overflow, simultaneously meets the traffic requirement of the top surface of the structure, and has the advantages of simple process and convenient construction.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
a permeable embankment and water retaining weir combined structure comprises a water retaining weir body, wherein a transition layer is arranged on the top surface of the water retaining weir body; an overflow layer is arranged above the transition layer, the overflow layer comprises a permeable embankment and a drain pipe which are arranged above the transition layer, and the drain pipe is embedded in the embankment and penetrates through the front side and the rear side of the water retaining weir body; an isolation layer and a pavement layer are sequentially arranged above the permeable embankment.
Further, the thickness of the permeable embankment is not less than 1.5 m.
Furthermore, the diameter of the drain pipe is 0.5m, and a plurality of water permeable holes with the diameter of 2cm are uniformly distributed on the pipe wall; and the adjacent drain pipes are arranged at a clear distance of 0.75 m.
The utility model has the beneficial effects that: the water retaining weir body is a water storage structure, the weir crest roadbed pavement structure mainly realizes a weir crest traffic function, and the water permeable embankment layer is internally provided with a drain pipe which mainly satisfies an overflow function and realizes water surface communication. And waterproof isolating layers are arranged between the permeable embankment layer and the weir crest roadbed pavement layer.
Specifically, the method comprises the following steps:
1. the elevation of the dam crest road surface is increased by arranging the permeable embankment layer pipe culvert, and the problems that the dam crest overflow and water overflow block traffic and the water passing road surface is poor in durability are solved.
2. The overflow position is changed through the permeable embankment layer, and the original weir crest overflow mode is changed.
3. The water permeable embankment is internally provided with the water drain pipe, so that the overflowing quantity of the water permeable embankment is increased.
4. Compared with the conventional culvert, the permeable embankment drain pipe has the advantages that the permeable area and the overflowing area are increased.
5. The small-diameter drain pipe is adopted in the permeable embankment, and special foundation treatment is not needed.
6. The structure does not need to be specially provided with reinforcing steel bars, the manufacturing cost is lower, the construction process is relatively simple, and the construction is convenient.

FIG. 2 is a schematic cross-sectional view taken at A-A of FIG. 1 in accordance with the present invention;
in the figure: 1. a water retaining weir body; 2. a transition layer; 3. a permeable embankment; 4. a drain pipe; 5. an isolation layer; 6. and (6) a road surface layer.
Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
The structure of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the permeable embankment and water-retaining weir combined structure provided by the embodiment of the present invention includes a water-retaining weir 1, wherein a transition layer 2 is disposed on a top surface of the water-retaining weir 1; an overflow layer is arranged above the transition layer 2, the overflow layer comprises a water permeable embankment 3 and a drain pipe 4 which are arranged above the transition layer 2, and the drain pipe 4 is embedded in the water permeable embankment 3 and penetrates through the front side and the rear side of the water retaining weir body 1; an isolation layer 5 and a pavement layer 6 are sequentially arranged above the permeable embankment 3, the isolation layer 5 isolates the permeable embankment 3 from the pavement layer 6, and the influence of water on the pavement layer 6 is avoided; road surface layer 6 mainly satisfies the weir crest traffic demand, adopts conventional roadbed pavement structure, and weir crest road surface elevation confirms convenient linking according to both sides road to satisfy requirements such as flood discharge drainage.
The water retaining weir body 1 is a main water retaining structure and supports an upper overflow layer and a pavement layer 6, and the weir body material should meet the water conservancy calculation requirements of the water retaining weir and meet the traffic requirements of the weir crest.
The stone used by the permeable embankment 3 has freezing resistance, and the dimension is not small enough and is uniform.
The working principle of the utility model is as follows:
during construction, firstly, the construction of a water retaining weir body 1 is completed, a transition layer 2 is laid on the top surface of the weir body, the thickness of a permeable embankment 3 is not less than 1.5m, the permeable embankment layer is made of freeze-resistant stones, and the grain sizes of the stones are uniform and consistent; when the permeable embankment 3 is laid, the drain pipes 4 are pre-buried, the diameter of each drain pipe 4 is 0.5m, a plurality of permeable holes with the diameter of 2cm are uniformly distributed on the pipe wall, and the adjacent drain pipes 4 are arranged according to the clear distance of 0.75 m;
when the water storage weir is used, the water retaining weir body 1 is a main water storage structure, and upstream water storage is realized through the water retaining weir body to form a water surface. The overflow layer is for conventional culvert structure, and the embankment that permeates water cooperates the drainage pipe form, has increased the water channel area to increased the overflow volume, satisfied the drainage waterlogging drainage requirement under the water level intercommunication of upstream and downstream and certain design standard. The pavement layer 6 mainly meets the traffic requirement of the top of the weir.
