The radiant type row seepage well of red mud dump
Technical field
The utility model relates to a kind of row's seepage well, relates in particular to a kind of radiant type row seepage well that is adapted to the red mud from sintering process stockyard.
Background technology
When the red mud from sintering process stockyard runs into and does beach length and can't guarantee, cause phreatic line too high, dam body may produce the slip crack.Therefore, must take measures to reduce the phreatic line height and guarantee the stable of dam body.Inside was established and is controlled its dried beach length when row is oozed net or stockyard operation when the measure of now general reduction phreatic line was the dam body construction.These methods can only influence the variation of the phreatic line on limit, dam, and sphere of action is limited.
The utility model content
For solve the problems of the technologies described above the utility model a kind of radiant type row seepage well of red mud dump, purpose being provided is to make the clarification of seepage flow water quality, can reclaim the seepage water of inside, stockyard and it is drawn the reservoir area, simple in structure, reliable operation, easy construction.
In order to solve the problems of the technologies described above, the utility model is such realization:
The radiant type row seepage well of red mud dump, its structure is as follows: the collection that is provided with radiation laterally on the borehole wall oozes pipe, and each collection oozes the pipe end and links to each other with vertical drainage pipe, is provided with the horizontal drainage pipeline of the infiltration in the borehole wall being drawn the reservoir area on the borehole wall.
The described borehole wall adopts prefabricated reinforced concrete building block, the tubular that is shaped as 2~5 meters of diameters of the borehole wall; About 0.3~1 meter of its base plate thickness is sealed for cast-in-situ reinforced concrete slab in borehole wall bottom.
Described collection oozes pipe for the perforated pipe road, and pipeline diameter is 0.05~0.2 meter, and length is 20~100 meters, and pipeline forms the gradient greater than 1% the gradient, and the pipeline gradient is to the borehole wall.
Two layers of geotextiles of outside parcel of described pipeline.
Described vertical drainage pipe forms diameter greater than 0.5 meter cylindrical drainage pipe jointly by 1-10 root sandpipe, and cylindrical drainage pipe oozes pipe with collection and links to each other.
Described horizontal drainage pipeline links to each other with the borehole wall, and the horizontal drainage pipeline is drawn the infiltration in the borehole wall with the slope ratio greater than 1%.
The diameter of described horizontal drainage pipeline is 0.1~0.2 meter a pipeline.
Described horizontal drainage pipeline is located at position on the borehole wall and is lower than collection and oozes the position of pipe on the borehole wall.
Advantage of the present utility model and effect are as follows: the phreatic line that the utility model is particularly useful for reservoir area in the red mud from sintering process stockyard reduces, radiant type row seepage well effectively oozes vertical row to ooze with level row and combines, influence basin is big, the clarification of seepage water quality can be reclaimed the seepage water of inside, stockyard and it is drawn the reservoir area.Radiant type row's seepage well easy construction and cost are less.Build radiant type row seepage well, can reduce the phreatic line storehouse in, the safety of raising dam body, and increasing or the condition that provides and its simple in structure, reliable operation be provided for dam body.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details, but protection domain of the present utility model is not limit by embodiment.
As Figure 1-3, the radiant type row seepage well of the utility model red mud dump, its structure is as follows: the borehole wall 1, adopt the method construction borehole wall 1 of open caisson, the collection that is provided with radiation laterally on the borehole wall 1 oozes pipe 2, and each collection oozes pipe 2 ends and links to each other with vertical drainage pipe 3, is provided with the horizontal drainage pipeline 4 of the infiltration in the borehole wall 1 being drawn the reservoir area on the borehole wall 1, the borehole wall 1 adopts prefabricated reinforced concrete building block 5, and the diameter of the borehole wall 1 is 2~5 meters tubulars; The borehole wall 1 bottom is that cast-in-situ reinforced concrete slab seals, about 0.3~1 meter of its base plate thickness, collection oozes pipe 2 and is UPVC pipeline 6 with holes, pipeline 6 diameters are 0.05~0.2 meter, length is 20~100 meters, pipeline 6 forms the gradients greater than 1% the gradient, pipeline 6 gradients are to the borehole wall 1, two layers of geotextiles 8 of outside parcel of pipeline 6, vertical drainage pipe 3 forms diameter greater than 0.5 meter cylindrical drainage pipe jointly by 1-10 root sandpipe 7, cylindrical drainage pipe oozes pipe 2 with collection and links to each other, horizontal drainage pipeline 4 links to each other with the borehole wall 1, horizontal drainage pipeline 4 is drawn the infiltration in the borehole wall 1 with the slope ratio greater than 1%, the diameter of horizontal drainage pipeline 4 is 0.1~0.2 meter a UPVC pipeline, and horizontal drainage pipeline 4 is located at position on the borehole wall 1 and is lower than collection and oozes the position of pipe 2 on the borehole wall 1.The hole of band and geotextiles 8 effect together are to collect seepage water on the pipeline 6.Greater than more than 2 times of pipeline 6 calibers, prevent that the perforate of concrete tube wall is too much in the center distance of concrete tube wall upper pipeline 6 and pipeline 6, the bearing strength of concrete tube wall descends too many.
