Description
Technical field
The utility model belongs to the cinder field that the technical field of drainage of cinder field, Tailings Dam engineering, the especially row of taking into account seep and drains off floodwaters
Culvert structure.
Background technique
In the engineering constructions such as highway, water conservancy, water power and mine, cinder field (or Tailings Dam) need to be generally set and stack excavation slag
Material, slag place is usually chosen in gully karness band, by the setting of slag region bottom of trench drain off floodwaters culvert downstream drain upstream come
Water is guided to infiltration in drainage pipe corridor (or french drain) to downstream excretion by the way that section infiltration system is arranged inside slag body.The prior art
To usually drain off floodwaters culvert and drainage pipe corridor (or french drain) is respectively arranged as independent structure, increases engineering cost, and right
Also increase the difficulty of work arrangement and construction in narrow channel.
Summary of the invention
Technical problem to be solved by the utility model is: a kind of cinder field discharge culvert structure that the row of taking into account seeps is provided, by ditch
Paddy type cinder field bottom of trench drainage pipe corridor is combined with concrete discharge culvert, is saved engineering cost, is facilitated work arrangement and construction.
The technical solution of the utility model is as follows:
A kind of cinder field discharge culvert structure that the row of taking into account seeps, including the culvert that drains off floodwaters, it is described to drain off floodwaters between culvert and slag body,
And slag body direction is directed toward by the culvert that drains off floodwaters and is disposed with pervious bed and loaded filter；
Arranged for interval has permeable hole on the wall surface of the culvert that drains off floodwaters, and permeable hole is embedded with non-return valve, and the non-return valve is worked as
When level of ground water is higher than water level in the culvert that drains off floodwaters, outside infiltration can pass freely through non-return valve and flow into discharge culvert, and level of ground water is low
In when water level in the culvert that drains off floodwaters, the non-return valve prevention water body inside culvert that drains off floodwaters is flowed outwardly.
Preferably, the wall surface of the culvert that drains off floodwaters includes side wall and hole top surface.
Preferably, the wall thickness of the culvert that drains off floodwaters is not less than the minimum length of non-return valve.
Preferably, the pore-size of the loaded filter is less than the partial size of slag body.
Preferably, the pervious bed is pieces of an egg stone pervious bed.
Preferably, the loaded filter is gradation sand gravel stratum or permeable geotextile layer.
Preferably, the non-return valve is fixed in permeable hole, and is in close contact with permeable hole hole wall.
The utility model eliminates bottom of trench drainage pipe corridor (french drain), and infiltration is introduced to culvert discharge of drainning off floodwaters, reduces engineering cloth
Difficulty and difficulty of construction are set, engineering cost is saved.
Detailed description of the invention
Fig. 1 is the typical structure sectional view of the utility model；
In figure: 1- drains off floodwaters culvert, 2- permeable hole, 3- non-return valve, 4- loaded filter, 5- slag body, 6- pervious bed, and Z1- drains off floodwaters
Water level in culvert, Z2- level of ground water.
Specific embodiment
As shown in Figure 1, being a kind of embodiment of the utility model:
The cinder field that a kind of row of taking into account seeps is drained off floodwaters culvert structure, and pieces of an egg stone is sequentially arranged between culvert 1 and slag body 5 drainning off floodwaters
Pervious bed 6 and loaded filter 4, the arranged for interval permeable hole 2 on 1 wall surface of culvert that drains off floodwaters, including side wall and hole top surface, while saturating
Water hole 2 is embedded in non-return valve 3.
Wherein, the wall surface requirement of culvert 1 of drainning off floodwaters is easy to aperture, and wall thickness is not less than 3 minimum length of non-return valve, usually adopts
Use concrete structure.
Wherein, the aperture of permeable hole 2 and spacing are calculated according to required row's milliosmolarity determines, minimum-value aperture must meet placement check
The requirement of valve 3.
Wherein, non-return valve 3 is completely embedded into the wall surface for the culvert 1 that drains off floodwaters, and is in close contact between permeable hole 2, does not slide, no
Leak；When level of ground water Z2 is higher than water level Z1 in the culvert that drains off floodwaters, outside infiltration can pass freely through non-return valve 3 and flow into discharge culvert 1；
Level of ground water Z2 is lower than when water level Z1 in the culvert that drains off floodwaters, and the prevention of the non-return valve 31 inside water body of culvert that drains off floodwaters flows outwardly.
Wherein, loaded filter 4 requires water penetration good, the infiltration in slag body 5 can pass freely through and enter pieces of an egg stone it is permeable
Layer 6, and 4 pore-size of loaded filter is less than 5 partial size of slag body, can prevent slag body fine granules from entering the blocking of pieces of an egg stone pervious bed 6
Non-return valve 3, the material that can be used as loaded filter 4 includes but is not limited to graded sand boulder and cobble or permeable geotextiles.
Wherein, 6 water penetration of pieces of an egg stone pervious bed is fine, can concentrate infiltration in slag body, and then will seep water by non-return valve 3
Introducing is drained off floodwaters culvert 1.
The specific implementation step of the utility model includes design procedure and construction procedure.
Wherein design procedure includes following process again:
1. calculating the structure size for determining the culvert 1 that drains off floodwaters；
2. determining the cross dimensions and number of permeable hole 2 by arranging seepage quantity calculation；
3. selecting suitable non-return valve 3 according to the arrangement parameter of permeable hole 2.
When construction, executed according to following processes:
1. drain off floodwaters 1 formwork erection of culvert；
2. installing fixed non-return valve 3 by design position, and protection is carried out to non-return valve 3；
3. pouring 1 concrete of culvert that drains off floodwaters；
4. filling pervious bed 6, loaded filter 4 and slag body 5.
