Abstract
The utility model relates to a reinforced compound needling earth work material, which is an earth work compound material compounded of earth work fabrics and earth work films. The utility model is suitable for construction work, such as water conservancy, road construction, etc. The utility model comprises nonwoven fabrics and plastic sheet materials. The utility model is characterized in that the utility model also comprises wire reinforced nets; the utility model is a laminar sheet material compounded of the wire reinforced nets, the nonwoven fabrics, and the plastic sheet materials. The utility model has the advantages of high strength, good light fastness, good thermal age resistance, excellent cold resistance, convenient construction, etc.
Description
The utility model is a kind of stratiform sheet material, is the compound geosynthetics of geotextile and geomembrane, construction project such as be applicable to water conservancy, build the road.
General hydraulic engineering antiseepage geotechnique material, as: the stratiform thing that artificial polyvinyl chloride leather or film and needle-punched non-woven fabric are compound, the one mask has hydrophobicity, and another side has the antiseepage water-based.This geotechnological material advantage is: the bonding connection seam of easy-to-use cementing agent, easy construction, has certain resistance to ag(e)ing, but because of containing a large amount of plasticizing agent and other auxiliary agent in artificial leather or the polychloroethylene film, especially in the medium-term and long-term use of water, the auxiliary agent migration can take place, thereby finally influence application life, can produce the defective that becomes fragile with the shock strength reduction.In addition, polyvinyl chloride low temperature bad mechanical property, minimum serviceability temperature depends on the content of plasticizing agent.Generally be not suitable for the working environment below 0 ℃.
The purpose of this utility model is: the enhancing composite acupuncture geotechnique material that a kind of enhancement mode is provided.
The utility model can be achieved through the following technical solutions: adopt composite molding technique to make stratified material by needle-punched non-woven fabric, enhancing gauze, plastic sheet or film.Make it when having had functions such as percolation-proof and hydrophobicity, also have well to strengthen effect.Described complex method is: acupuncture is compound, heat is melted technologies such as compound with adopting behind layers of material lay successively.Described enhancing gauze is to be spun into line with long fibres such as polypropylene fibre, terylene, is made into net then.Strengthen the one or both sides that gauze is layered on needle-punched non-woven fabric, also can be in the middle of two layers of nonwoven fabric with the splicing thread network folder.Described plastic sheet is selected for use and is contained the few or not solvent-laden material of quantity of solvent, as: polyethylene etc. are as geomembrane.Described acupuncture combination process is that needle-punched non-woven fabric and enhancing gauze are made for one, that is: when making nonwoven, at first, on polypropylene short fiber, spread gauze, or on polypropylene short fiber and below all spread gauze, or gauze is clipped in the middle of the two-layer polypropylene short fiber, carry out pre-needling, positive acupuncture then, fall acupuncture and make and strengthen polypropylene fibre soil fabric, strengthen gauze, the compound stratiform sheet material of plastic sheet.Described heat melt compound be directly by adhesive-bonded fabric, strengthen gauze, plastic sheet fusion and make the stratiform sheet material after compound.The utility model has carried out the anti-aging processing to selected material, makes that it is fast light, hot, the oxygen aging performance is superior.
The utlity model has the intensity height, characteristics such as fast light, that heat aging performance good, and cold resistance is superior, and easy construction.Describe in detail below by embodiment.
Accompanying drawing strengthens composite acupuncture geotechnique material for 1 three layers.
Accompanying drawing 2 presss from both sides the enhancing composite acupuncture geotechnique material of one deck gauze in two layers of nonwoven fabric.
Accompanying drawing 3 all is covered with the enhancing composite acupuncture geotechnique material that strengthens gauze at the upper and lower faces of adhesive-bonded fabric.
Accompanying drawing 4 all has the enhancing composite acupuncture geotechnique material of adhesive-bonded fabric on the geomembrane two sides.
Embodiment 1: as Fig. 1, be three layers and strengthen composite acupuncture geotechnique material that it is composited by adhesive-bonded fabric (1), enhancing gauze (2), plastic sheet (3) successively.Moulding process is: spread gauze on polypropylene short fiber, the hand-manipulating of needle of going forward side by side stings technology and makes the enhancing geotextile, and geotextile and the fusion of low density polyethylene (LDPE) calendered sheet that strengthens is composited.
Embodiment 2: the utility model is composited by adhesive-bonded fabric (1), enhancing gauze (2), adhesive-bonded fabric (11), plastic sheet (3) successively.Earlier adhesive-bonded fabric, enhancing gauze, adhesive-bonded fabric are made the enhancement mode geotextile during fabrication, compound with the polyethylene film fusion then.
Embodiment 3: as Fig. 2, be four layers and strengthen composite acupuncture geotechnique material that it is composited by enhancing gauze (21), adhesive-bonded fabric (1), enhancing gauze (2), plastic sheet (3) successively.Its moulding process is: on polypropylene short fiber and below spread gauze, the hand-manipulating of needle of going forward side by side thorn technology and make the enhancing adhesive-bonded fabric is composited adhesive-bonded fabric and the fusion of LLDPE calendered sheet that strengthens.
Embodiment 4: as Fig. 3, be four layers and strengthen composite acupuncture geotechnique material that it forms enhancing composite acupuncture geotechnique material by adhesive-bonded fabric (12), plastic sheet (3), enhancing gauze (2), adhesive-bonded fabric (1) successively.
The nonwoven fabric layer of this example has superior hydrophobicity, and plastic sheet has good percolation-proof performance, and the mechanical strength that the density of enhancing gauze is exchanged the abridged edition utility model plays good effect.
