Abstract
The utility model relates to a watertight screen with a water filtering layer guiding groove, which comprises punched non woven geotextile, a watertight screen and a convex and concave watertight screen laid between the punched non woven geotextile and the watertight screen. The watertight screen is formed by rolling, thermal sealing and compounding, the water filtered by the punched non woven geotextile is led out through the water guiding groove formed on the convex and concave watertight screen, thereby the effects of waterproof and seepage-prevention are realized. The watertight screen has the advantages of high temperature resistant, freezing resistant, antidecomposition, aging resistance, anticorrosion, asphalt oil and tar resistance, acid corrosion tolerance, alkali corrosion tolerance and salinity corrosion tolerance, exposed operation and long service life; the watertight screen has the advantages that the operation is simple, the construction is quick, the joint close strength is high, and can be widely applied to the civil engineering, the hydraulic engineering and the environment engineering, such as water conservancies, dams, air ports, highways, railways, subways, culverts, tunnels, river channels, waterproof, water supply and drainage, refuse landfills and sewage disposal plants.
Description
Technical field
The utility model relates to a kind of splash guard with drainage layer guiding gutter.
Background technology
Current, basic unit's waterproof of highway and railway slope; The processing of impervious barriers such as the isolation of earth rock cofferdam weak soil and piece stone, tunnel, reservoir dam, river course, gutter, artificial lake; Isolation and antiseepage between refuse landfill, sewage-farm filtrate and the rubbish, these national basis Facilities Construction engineerings all relate to the water proof anti-seepage problem.Use a large amount of common splash guards now on the engineering, do not have water guide drainage layer, expose the weakness of drainability difference, make the decline of the impervious effect of engineering integral waterproofing.
Summary of the invention
In view of the problem that above-mentioned common splash guard occurs in the water proof anti-seepage engineering, the purpose of this utility model aims to provide a kind of splash guard with drainage layer guiding gutter.Promptly between perverse non-woven geotextile of pin and splash guard, lay the splash guard that one deck has convex-concave, the water that the perverse non-woven geotextile of pin leaches is derived, reach the effect of water proof anti-seepage with this by the guiding gutter that the convex-concave splash guard forms.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of splash guard with drainage layer guiding gutter contains the perverse non-woven geotextile of pin, splash guard, lays one deck convex-concave splash guard between perverse non-woven geotextile of pin and splash guard, the calendering, heat and be composited.
Above-mentioned geotechnological splash guard and convex-concave splash guard are polyvinylchloride splash guard or polythene PE splash guard or high-molecular polythene HDPE splash guard or ethylene-vinyl acetate copolymer EVA splash guard.
The perverse non-woven geotextile of above-mentioned pin is the long filament non-woven geotextile, or short silk non-woven geotextile.
The beneficial effect of advantage of the present utility model and generation is:
1, the utility model barrier performance is good.Lay one deck convex-concave splash guard between perverse non-woven geotextile of pin and splash guard, the water that the guiding gutter that forms by the convex-concave splash guard leaches the perverse non-woven geotextile of pin is derived and is drained, and has the incomparable anti-seepage effect of common waterproofing materials; Perverse non-woven geotextile of pin that adopts and splash guard are poison ring and protect material, and antiseepage, water conservancy diversion are common physical changes, do not produce any hazardous substances;
2, by gluing, calendering, heat seal, the coextrusion process geosynthetics that is composited, it has excellent mechanical intensity to the utility model, excellent elasticity and deformability by the perverse geotextiles of pin and splash guard.Physical and mechanical property indexs such as tension, tear-proof, the anti-bursting value of CBR, transmission coefficient are higher than common waterproofing materials, and the stab resistant ability is strong, and being applicable to expands shrinks basal plane, can overcome the uneven subsidence of basal plane; Texture material is firm, and compact conformation has good water proof anti-seepage, isolation and reinforcement protection effect, anti-permeability is good, high temperature resistant, anti-freezing, anti-decomposition, ageing-resistant, corrosion-resistant, anti-pitch, oil and tar, chemical attack such as acid and alkali resistance, salt can be exposed use;
3, the utility model is easy and simple to handle, construction fast, the welding of the gluing or heat seal bonding machine of junction all can, joint close intensity height, save the cost cost, improve the impervious effect of engineering waterproofing, can be widely used in civil engineering, hydraulic engineering and Environmental Engineerings such as railway, highway, sports buildings, artificial dykes and dams, civil construction, culvert tunnel, coastal (river) embankment, sewerage treatment chemical industry pond, refuse landfill.
