Description
Technical field
The utility model relates to a kind of catch pit, relates in particular to the window type catch pit that Tailings Dam tailings storage backwater tapered or that catchment area is less drains off floodwaters.
Background technology
Catch pit is one of important structure of mill tailings facility, the sleet water and the tailing clearing rinsing that drop in Tailings Dam catchment area mostly pass through it, discharge outside storehouse through structure such as drainage culvert or tunnels subsequently, pushed up and make tailing clearing rinsing to return to ore dressing plant to reuse by flood is unrestrained to guarantee that tailing dam is unlikely.When the required drainage structures discharge capacity of Tailings Dam hour, generally adopt window type catch pit.The advantages such as window type catch pit system once builds up, and place leaves draining window in borehole wall different level, and it is good that this well has structural integrity, and hole diameter is little, and working service is easy, but bleeder quantity is little.
Window type catch pit well bore is made by steel concrete, comprises pit shaft and well seat, and pit shaft is positioned at the top of well seat, pit shaft is provided with the borehole wall, the borehole wall is provided with draining window, and the inwall of draining window is truncated cone-shaped, and outside diameter is large, inside diameter is little, existing draining window shutoff is used concrete stopper, concrete stopper heavy 52kg (outer end diameter phi 300mm, inner diameter phi 350mm that each shutoff is used, long 250mm), see Fig. 1, Fig. 2 and Fig. 3.At draining window, the concrete plug period of the day from 11 p.m. to 1 a.m is installed, need be by concrete stopper from moving to ship on the bank, then be installed on the draining window of catch pit from ship, carrying effort, and be difficult for stifled sternly, easily leak ore pulp.When concrete stopper construction deviation is larger, may not install, and sealing is poor.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of window type catch pit is provided, and this window type catch pit both can be used to drain off floodwaters, and adopts flange shutoff window, shutoff good sealing effect; Also catch pit can be transformed into collection seepage well, collection oozes effective.
Technical scheme to be solved in the utility model is: a kind of window type catch pit, comprise pit shaft and well seat, pit shaft is positioned at the top of well seat, pit shaft is provided with the borehole wall, the borehole wall is provided with draining window, the inwall of draining window is truncated cone-shaped, and draining window is provided with reduced pipe, and the inwall of the outer wall of reduced pipe and draining window is suitable; The inner chamber of reduced pipe is provided with cage, and the inwall of cage and reduced pipe is suitable, is filled with filter in cage, and the outside of reduced pipe is provided with the 1st flange.
As improvement, the outside of above-mentioned cage is provided with outer anti-limit, and outer anti-limit contacts with the lateral surface of the 1st flange.
Above-mentioned filter comprises the gravel bag of filter, geotextiles parcel and the coarse sand bag of geotextiles parcel, coarse sand bag is positioned at the outside of gravel bag, the inner side of gravel bag is filter, coarse sand particle diameter in coarse sand bag is 1～20mm, grain size of gravel in gravel bag is 20～60mm, and filter is provided with treatment hole.
As improvement, above-mentioned the 1st flange has been bolted the 2nd flange, and the 2nd flange is provided with filter bores, and the 2nd flange is connected with collection and oozes device.
Above-mentioned collection oozed device as plastic blind-ditch, or flexible porous tube, or geotechnological straw mats.
As improvement, the exposed surface of above-mentioned reduced pipe, the 1st flange and the 2nd flange is coated with geotextiles.
As improvement, the inner side of above-mentioned reduced pipe is provided with the 3rd flange.
Above-mentioned the 1st flange has been bolted blind flange dish.
Technique effect of the present utility model is: the draining window of a kind of window type catch pit of the utility model is provided with reduced pipe, and the inner chamber of reduced pipe is provided with cage, is filled with filter in cage, and the outside of reduced pipe is provided with the 1st flange.In the time that the 1st flange is subject to exterior side to pressure-acting, reduced pipe outer wall contacts tightr with draining window inwall, and reduced pipe is combined more firm with draining window.Cage content Nano Filtration device, for filtering native draining, can filter out the sand in water, prevents " running mixed ", oozes when also can be used for row after window shutoff, reduces the phreatic line in tailing dam.The outside of cage is provided with outer anti-limit, and outer anti-limit contacts with the lateral surface of the 1st flange, is convenient to cage to be fixed in reduced pipe.Filter comprises the coarse sand bag of filter, geotextiles parcel and the gravel bag of geotextiles parcel, good filtration effect, and cost is low.Exposed surface at reduced pipe, the 1st flange and the 2nd flange is coated with geotextiles, further increases filter effect.The inner side of reduced pipe is provided with the 3rd flange, is further used for fixing reduced pipe.Flange connects, and mounting or dismounting are convenient.The 1st flange both can connect blind flange dish, was used for shutoff draining window; The 1st flange also can connect the 2nd flange, and the 2nd flange is connected with collection and oozes device, and catch pit is used as collection seepage well, accelerates tailings discharging consolidation in storehouse.Therefore, the utility model uses flexibly, reaches dual-use material, reduces investment outlay.Because reduced pipe and flange are the finished product of produce in factory, the sealing of shutoff will be much better than concrete stopper, installs and is also easier to.The roughness coefficient (n=0.011) of steel pipe is less than the roughness coefficient (n=0.014～0.017) of concrete face, for the discharge capacity of single window, be greater than existing concrete draining window with the discharge capacity of the utility model draining window of diameter.The utility model changes the shutoff of concrete stopper to adopt blind flange and bolt, weight to be about 0.2～0.5 times of concrete stopper weight that same diameter window uses into, and component weight is light, more convenient operation.
