Abstract
The utility model relates to a drainage-proof composite rubber-plastic plate for a tunnel, which comprises a framework layer 1 and a water proof layer 2, wherein, the framework later 1 is a non-woven fabric layer. The water proof layer 2 compounded on one side of the framework layer 1 is a rubber-plastic water proof layer plate. The utility model has the advantages of good water drainage proof effect, aging resistance, penetration resistance and good acid-alkali resistant performance. The drainage-proof composite rubber-plastic plate for a tunnel can be preformed into large pieces of soft sectional materials in the factory, and thus the randomness is good, the construction is convenient and the manufacturing process is simple. The drainage-proof composite rubber-plastic plate for a tunnel can be nailed to be hung or hung, which enables the construction progress to be accelerated and the integrate cost to be reduced. The utility model is mainly used for drainage-proof projects of roads, railways, tunnels, underground projects, etc.
Description
The utility model relates to a kind of compound rubber and plastic offset plate with layer structure, particularly a kind of compound rubber and plastic offset plate that is used for the tunnel water handling engineering.
Along with modern railways, Freeway Development, the anti-draining in tunnel is more and more important.For example CN2109296Y discloses " a kind of canvas filler rubber plate that is used for tunnel waterproofing engineering ", it is to make framework material with the high intensity glass fiber cloth that has flooded resin latex, the chlorinated polyethylene rubber layer of the compactness good film-forming property of the bonding high resiliency of its upper and lower surface, high elongation.The rubber tile of this structure makes the elastomeric chlorinated polyethylene rubber layer of this tool lose extensibility owing to adopt glass fabric to make framework material, and not soft, and is random poor, and glass fabric is not had a function of waterproof, draining.This material is used for tunnel water handling needs to lay earlier drainage blanket, re-lays this splash guard, carries out the construction of two steps and just can finish waterproof drainage, and such material and form of construction work not only speed are slow, the comprehensive cost height; And finally anti-drainage effect is poor.
The purpose of this utility model is to provide a kind of tunnel water handling engineering that is used for can simplify construction sequence, has waterproof, hydrophobic function simultaneously, compound rubber and plastic offset plate rational in infrastructure.
The utility model is achieved in that a kind of compound rubber and plastic offset plate that is used for the tunnel water handling engineering, and it comprises casing play and waterproof lamellar, it is characterized in that: described casing play is a nonwoven layer; This casing play simultaneously is compounded with the rubber and plastic waterproof lamellar.
In order to improve its puncture resistance, can in waterproof lamellar, be provided with the skeleton fabric, such as glass fiber.
Wherein said casing play can be the nonwoven layer of being made by polypropylene fiber or vinylon fiber or polyster fibre or polypropylene fibre, and it is punctured as skeleton protection waterproof lamellar again simultaneously not only as hydrophobic, draining.
Described rubber and plastic waterproof lamellar is macromolecular elastomer waterproof lamellar or plastics waterproofing flaggy, wherein the macromolecular elastomer waterproof lamellar is made by thermoplastic elastomer (TPE) or thermo-setting elastomer, as haloflex, thermoplasticity butadiene-styrene rubber, second third glue, thermosetting natural rubber and synthetic rubber; Wherein the plastics waterproofing flaggy can be polyethylene, polyvinyl chloride, polypropylene and ethylene-vinyl acetate polymer.
From reducing cost, the angle that increases the service life is set out, and the weight of casing play is with 200-400 gram/m
2Or thickness is best with 2-5mm; The thickness of waterproof lamellar is best with 0.2-2mm.
The nonwoven layer of this sheet material also as the water-proof drainage material layer, is added the anti-draining of compound rubber and plastic waterproof lamellar not only as the framework material layer, and its anti-drainage effect is very good; Simultaneously ageing-resistant, anti-puncture, acid-proof alkaline is good; This sheet material can be prefabricated into large stretch of soft section bar in factory, and is random good, be convenient to construction, and technology is simple, nail hang or hang all can, like this can accelerating construction progress, the reduction comprehensive cost.This material is mainly used in highway, railway, tunnel, the waterproof drainage of underground construction etc.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1. the structural representation of the utility model embodiment 1.
Fig. 2. the structural representation of the utility model embodiment 2.
Referring to Fig. 1, a kind of compound rubber and plastic offset plate that is used for the tunnel water handling engineering, it comprises casing play 1 and waterproof lamellar 2, and wherein casing play 1 is a nonwoven layer, and the compound waterproof lamellar 2 of this casing play 1 one side is the rubber and plastic waterproof lamellar.
Wherein said casing play 1 can be the nonwoven layer of being made by polypropylene fiber or vinylon fiber or polyster fibre or polypropylene fibre.
The weight of above-mentioned casing play 1 is with 200-400 gram/m
2Or thickness is best with 2-5mm.
Described rubber and plastic waterproof lamellar 2 can be macromolecular elastomer waterproof lamellar or plastics waterproofing flaggy, wherein the macromolecular elastomer waterproof lamellar is made by thermoplastic elastomer (TPE) or thermo-setting elastomer, as haloflex, thermoplasticity butadiene-styrene rubber, second third glue, thermosetting natural rubber and synthetic rubber; Wherein the plastics waterproofing flaggy can be polyethylene, polyvinyl chloride, polypropylene and ethylene-vinyl acetate polymer.
The thickness of above-mentioned waterproof lamellar is best with 0.2-2mm.
Referring to Fig. 2,, also can in waterproof lamellar 2, set up skeleton fabric glass fibre 3 in order to improve its puncture resistance.
