Description
Technical field
The utility model relates to a kind of mine tailing storehouse seepage flow type back water well, relates in particular to a kind of seepage flow type back water well that is adapted to dry method red mud storage yard or dry method mine tailing storehouse.
Background technology
When the water ratio of red mud or other mine tailings was 50% left and right sides, promptly liquid-solid ratio was 1: 1.The particle of red mud is thin, and the attached liquid amount is little, and particle suspension is difficult to occur primary water in attached liquid.When at the tailings discharging dry method storage yard, when its gradient along with the bottom surface, reservoir area flow to back water well, denseness was still very big, can not form the primary water liquid level, so require back water well not only can return water in can not clarifying mine tailing, and along with the rising of mine tailing face, back water well can work always.
The utility model content
Technical problem to be solved in the utility model is: a kind of seepage flow type back water well that is adapted to the dry method storage yard in dry method mine tailing stockyard is provided, and purpose is the backwater problem that solves dry method mine tailing stockyard.
In order to solve the problems of the technologies described above, the utility model is such realization: a kind of seepage flow type back water well of dry method storage yard, its structure is for adopting steel pipe with holes as well bore, add ribbed stiffener in the well bore outside, the layer of displacement that well bore outside layering is banked up and formed by stone, the well bore lower end connects the well basis, and the well basis links to each other with horizontal pipeline.
Described well bore is to be formed by connecting by multistage steel pipe with holes, and adjacent two sections steel pipes connect through ring flange.
Described steel pipe with holes is positioned at the steel pipe height of lower end greater than the steel pipe height that is positioned at its top.
Described layer of displacement is the multi-stage type result, connects through sand bedding course between the adjacent drainage channel layer.
The gradient of described sand bedding course is 1: 1-3.
The thickness of described sand bedding course is 350-600mm.
Described every section layer of displacement height is about 2-5m.
Described three layers of varigrained stone layer structure are: every section layer of displacement is to be made of three layers of varigrained stone layer, and the stone granularity of stone layer that is positioned at the bottom is greater than the stone granularity of the stone layer that is positioned at its top.
Described outside the first layer is a coarse sand, and thickness is 0.3-0.6m; The second layer is a gravelly sand, and thickness is 0.3-0.6m; The 3rd layer is rubble, and minimum thickness is 0.3-0.8m.
The gradient of described layer of displacement is 1: 1.2-2.
The spacing of described ribbed stiffener is 0.6-1.5m.
Advantage of the present utility model and effect are:
The utility model seepage flow type back water well not only can be collected attached liquid in the mine tailing, but also can drain the stockyard rainwater in time.Attached liquid in its effective collection " dry method " mine tailing, the clarification of backwater quality the phenomenon that scabs can not occur on steel pipe walls.Its segmentation is built, and can reduce the effect of a large amount of wind loadings to back water well, can save construction cost, and the process of increasing is simple, is convenient to site operation.The utility model is simple in structure, reliable operation, solved the backwater problem in dry method mine tailing stockyard.
Description of drawings
Fig. 1 is the structural representation of the seepage flow type back water well of the utility model dry method storage yard.
Among the figure, 1, well bore; 2, steel pipe rib; 3, layer of displacement; 4, sand bedding course; 5, horizontal pipeline; 6, well basis; 7, ring flange; 8, red mud or other mine tailings.
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 shown in Figure 1, the structure of the seepage flow type back water well of the utility model dry method storage yard and construction process are as follows:
Well bore 1 adopts steel pipe with holes to make, it can be whole also can be the structure of sectional type.If the well bore of segmentation structure 1, the height of 1 first section construction of well bore is a little more than the height of dam of initial dam.In addition, well bore 1 outside adds ribbed stiffener 2 every 0.6-1.5m, if the flexing phenomenon takes place when preventing that well bore 1 from having the big area preloading in the above in ribbed stiffener 2, adopt ring flange 7 to connect between adjacent two sections steel pipes, well bore 1 lower end connects the well basis 6 of alkali-resistant concrete, well basis 6 links to each other with horizontal pipeline 5, will seep water to collect and converge to the backwater pump house, then well bore 1 outside layering layer of displacement 3 banking up and formed by the different grain size stone.
Described layer of displacement 3 can be that the stone layer by three kinds of different-grain diameters constitutes, and cobble-stone diameter is chap successively by skin to nexine.Outside the first layer is a coarse sand, and thickness is 0.3-0.6m, and effect is to prevent that the red mud particle from entering layer of displacement; The second layer is a gravelly sand, and thickness is for being 0.3-0.6m, and effect is to prevent that coarse sand particles from entering down the transition layer of one deck; The 3rd layer is rubble, and minimum thickness is 0.3-0.8m, and effect is to form hole, and pore water pressure is reduced to 0, forms free water, converges to back water well.Because stone is a discrete particle, must bank up and could stablize with certain gradient, and the phenomenon of slippage does not take place.Therefore the final gradient that forms of the stone after rolling is 1: 1.2-2, the i.e. gradient of layer of displacement 3.Layer of displacement 3 every section do about 2-5m, if once do too high, then waste of material is too big, also takies storage capacity.Every layer of stone must guarantee certain thickness in the stone 3 of three kinds of different-grain diameters.
Along with the rising in red mud dump or mine tailing stockyard, seepage flow type back water well is also constantly increased.Be divided into for three steps when increasing: steel pipe 1. with holes top gradation adds steel pipe with holes 1, but length of pipe section suitably reduces.Adopt ring flange 7 to connect between the adjacent steel pipe, length of pipe section can be carried with 1～2 people and be advisable; 2. dig out near the red mud or the mine tailing 8 of end face of seepage flow type back water well, its maximum diameter size is identical with the diameter of the stone 3 of three kinds of different-grain diameters, with 1: the gradient of 1-3 is dug downwards, its thickness is 350-600mm, makes sand bedding course 4 in such hole, and the purpose of doing like this is in order to take out weak soil layer, prevent weak native deformation failure layer of displacement structure, and when layered rolling formed sand bedding course 4, a large amount of distortion was subdued, and sand bedding course 4 has the effect that disperses top enrockment pressure in addition; 3. the way of the stone layer of three of the preceding paragraph layer of displacement kinds of different-grain diameters is identical with the way of the stone layer of following three kinds of different-grain diameters.
