Abstract
The utility model relates to a semi-rigid leakage-removing pipe for an ash-dam, which relates to a building element of underground drainage. A pipe wall supporting body of the utility model is pasted with a water penetration filtering layer, the pipe wall supporting body is a stainless steel elasticity spiral coil, and the water penetration filtering layer is a winding tubular body of which the frame is made of plastic longitudinal thread. The utility model is characterized in that the inner side of a coil is provided with a stainless steel reinforcing rib on a shaft direction, the outer side of the coil is bonded with the inner layer plastic longitudinal thread of the filtering layer, the outside of polypropylene fibre long thread which is wound on the inner layer plastic longitudinal thread is non-woven geotextile filtering cloth, and the non-woven geotextile filtering cloth and the polypropylene fibre long thread on the outmost layer of the filtering layer are connected into integration through the bonding of the outer layer plastic longitudinal thread. The utility model also has definite rigidity on the basis that the utility model has elasticity, and the utility model can effectively prevent the movement of a radial direction and a shaft direction in the process of use. The leakage-removing pipe has the advantage of large compressive strength, the filtering layer with a five-layer structure can have good water penetration performance as well as can avoid that tiny ash and dust enter the pipe body of the pipe, and the utility model is especially suitable for ash dams of heat power plants and leakage-removing systems of trailing dams of metallurgy and mine systems.
Description
The utility model relates to a kind of underdrainage building unit, the semi-rigid grey dam drainage pipe of particularly a kind of grey dam that is used for the steam power station and metallurgy, mine system tailing dam.
The grey dam of steam power station and metallurgy, the mine system tailing dam row system of oozing generally adopt the conventional concrete draining, thin ash component height in the sewage of discharge, contaminated environment in use, often occur stopping up causing impeded drainage.Desirable row is oozed the system requirements one side can keep off ash, does not promptly allow thin ash to infiltrate in the pipe and causes silting to make impeded drainage, avoids environment pollution, and the ponding infiltration drainage pipe in the grey dam is discharged outside the dam.In draining field, stratum, a series of soft gutter has appearred, as Chinese patent CN2238852Y, it discloses a kind of " bullet is moulded flexible porous tube ", comprise the tube wall supporting mass, permeable filtration beds is characterized in that inboard tube wall supporting mass is made up of helical spring steel ring wild card plastics card article, the internal layer of permeable filtration beds is and plastic bonding terylene nonwoven together that skin is the polypropylene fiber long filament that is wrapped on the terylene non-woven fabric.This body has certain crushing resistance, and the flexibility height is freely scalable at length direction.As if the draining that this pipe is used for grey dams such as steam power station, also existing problems.One of problem, the draining of grey dam not exclusively is equal to the surface soil draining, and particle size of dust is small, the permeability height, it requires higher to filtration beds, must guarantee to isolate dust; Two of problem, gutter is if be given a shock, during external power such as push-and-pull, and the flexible porous tube that elasticity is too big is easy to generate radially, axially-movable, and particularly axially-movable causes the filtration beds part overlapping, and the influence infiltration makes impeded drainage.
The utility model provides a kind of grey dam drainage pipe that prevents footpath, axially-movable that ash is effective, permeability rate is high, not yielding, the existing certain elasticity of resistance to compression is not lost rigidity again that keeps off just in order to overcome above-mentioned deficiency.
Being achieved as follows of the utility model purpose: a kind of semi-rigid grey dam drainage pipe, be pasted with permeable filtration beds on its tube wall supporting mass, described tube wall supporting mass is a stainless steel elastic helix coil, permeable filtration beds is one to make the tubular body that is entwined of skeleton with the plastics ordinate, it is characterized in that the coil inner shafts is to being equipped with the stainless steel ribs, the inner plastic ordinate of outside bonding filtration beds, being wrapped in polypropylene fiber long filament on the inner plastic ordinate is outward nonwoven geotechnique filter cloth, fuses through the bonding and the outermost polypropylene fiber long filament of filtration beds of outer layer plastic ordinate.The utility model adopts stainless steel elastic thread coil, mainly be to guarantee body non-corrosive in use, life-saving, face down bonding connects the stainless steel ribs in coil, can have on certain flexible basis at it and increase rigidity, radially particularly axial motion takes place when avoiding body in use to be subjected to external shock, influences its infiltration effect.The filtration beds of drainage pipe is designed to five layers, is the requirement of considering its retaining ash, because dust is small, permeability is strong, filter cloth is interposed in the two-layer polypropylene fiber, and it is respond well that it filters dirt, and the setting of inside and outside two layers of plastic ordinate has guaranteed that whole filtration beds is integral by secure bond.
Ribs of the present utility model is uniformly distributed in the coil inboard, is provided with four generally speaking, makes stressed more evenly, and anti-axially-movable effect is more obvious.
Two layers of plastic ordinate in the utility model filtration beds all equidistantly is provided with, inside and outside be staggered, both guaranteed the seepage of water that it is good, strengthened the adhesive fastness of filtration beds again.
The utility model adopts the method that increases ribs just, make grey dam drainage pipe have certain rigid, can effectively prevent in the use radially, axially-movable, compressive strength is big, the filtration beds of five-layer structure can well seep water, avoided small dirt to enter body again, the row who is specially adapted to the grey dam of steam power station and metallurgy, mine system tailing dam is oozed system.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is A-A figure.
Further specify the utility model below in conjunction with embodiment:
A kind of grey dam and metallurgy that is used for the steam power station, the semi-rigid grey dam drainage pipe of mine system tailing dam, make the tube wall supporting mass with stainless steel elastic helix coil 1, its inner shafts is to being equipped with four stainless steel ribs 2 and evenly distributing, the outside is bonded with filtration beds 3, the innermost layer of filtration beds 3 is a plastics ordinate skeleton, the one side is bonded in stainless steel elastic helix coil 1 outside, the polypropylene fiber long filament that the opposite side bonding is entwined, it is outer to be one deck nonwoven geotechnique filter cloth, filter cloth fuses through the bonding and the filtration beds 3 outermost polypropylene fiber long filaments of plastics ordinate, all equidistant setting of two layers of plastic ordinate and interlaced arrangement, whole filtration beds 3 inside and outside secure bond constitute a tubular body, are concavo-convex that crest and trough take turns.
