Abstract
The utility model relates to a mechanical means for preventing dam piping, in particular to a monolithic anti-filtering and anti-surrounding well. The technical scheme is that 2 to 4 baffle boards, the diameter of which is from small to big, are sequentially arranged in interval in a taper bucket with a thick upper portion and a thin lower portion from top to down, each layer of the baffle boards is equally provided with a plurality of holes, filtering materials are filled among the baffle boards, and an overflow pipe is arranged at one side of the upper portion of the taper bucket. The advanced scheme of the technical scheme further comprises that the bottom portion of the baffle boards is fixed with a stud which is positioned in the shaft center of the taper bucket, the upper baffle boards are sequentially sleeved on the stud, the top portion of the stud is provided with a hand wheel brace engaged with screw threads of the stud, the lower portion of the hand wheel brace is connected with a top baffle board via a washer, and a canvas washer is fixed on the bottom edge of the taper bucket. The utility model has simple structure, convenient use, and is capable of achieving wall surrounding and flow guiding, thereby saving time and energy.
Description
Technical field
The utility model relates to the mechanical device of preventing and treating dike piping, specifically is that well is enclosed in the anti-filter of a kind of monolithic.
Background technology
Dike piping is the key factor of harm embankment safety, present solution is that gushing outside dykes and dams stacked the sandstone bag around the hole and surrounded well, and upwards in the process of jet flow, sedimentation is in enclosing well from enclose well in piping, water is from enclosing aboveground mouthful the outflow, and silt sediment is alleviated with shutoff and gushed the hole successively.The defective of this method is that speed of application is slow, under the bigger situation of hydraulic pressure, has little time to enclose well at all, and the deposition of silt is also very slow, and giving speedily carries out rescue work brings very big difficulty.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provides the anti-filter of a kind of quick and easy monolithic to enclose well.
Its technical scheme is: at interval 2-4 diameter dividing plate from small to large is set successively from top to bottom in a up-thin-low-thick awl staving, is equipped with a plurality of holes on every layer of dividing plate, be filled with filtering material between the dividing plate, the side on awl staving top is provided with bleed off pipe.
The improvement project of such scheme also comprises: fix a column that is positioned at awl staving axle center on the bottom baffles, top dividing plate is sleeved on the column successively, take turns with the hand of column threaded engagement in the setting of the top of column, the hand bottom of taking turns is connected with the top layer dividing plate by packing ring, is fixed with the canvas packing ring on the bottom margin of awl staving.
The utlity model has simple in structurely, easy to use, the piping danger that occurs for dykes and dams can realize enclosing well and drainage fast, and is time saving and energy saving.
Description of drawings
The specific embodiment:
During use, at first will bore staving is buckled in together with four layers of dividing plate in it and filtering material and gushes the hole periphery, the silt that gushes the hole discharge flows along the hole and the filtering material of dividing plate and makes progress step by step, before big top layer dividing plate, silt precipitates substantially, water is drawn by bleed off pipe, has so just realized gushing the quick blocking in hole.
Owing to increased the canvas packing ring of bottom, gush the hole periphery not too smooth in, can well organize silt stream to overflow from awl staving bottom periphery; The hand effect of taking turns is according to the flow that gushes hole silt stream, progressively overstocks filtering material, is the more thorough of sedimentation, finally reaches the purpose of shutoff piping.
Used filtering material is selected according to the size of piping flow and pressure, can use coarse fodders such as branch, stalk, straw, also can adopt the less fabric screen in space etc.
Claims (2)
1. well is enclosed in the anti-filter of monolithic, it is characterized in that: 2-4 diameter dividing plate from small to large is set in a up-thin-low-thick awl staving from top to bottom successively at interval, be equipped with a plurality of holes on every layer of dividing plate, be filled with filtering material between the dividing plate, the side on awl staving top is provided with bleed off pipe.
2. well is enclosed in the anti-filter of monolithic according to claim 1, it is characterized in that: fix a column that is positioned at awl staving axle center on the bottom baffles, top dividing plate is sleeved on the column successively, take turns with the hand of column threaded engagement in the setting of the top of column, the hand bottom of taking turns is connected with the top layer dividing plate by packing ring, is fixed with the canvas packing ring on the bottom margin of awl staving.
