Abstract
A waterproof board specialized for tunnels comprises a non-woven earthwork cloth layer (1), a support plate (3) and a waterproof board (2) which are sequentially arranged in a layered way and integrally compounded through calendaring, heating and co-extrusion. The support plate (3) is a layered plate composed of boned fabric. The waterproof board provided in the utility model has excellent anti-seepage performances. Compared with a common waterproof material, the waterproof board provided in the utility model has the characteristics of better tensile resistance, better tearing resistance, higher CBR bursting resistance value and higher penetration coefficient, etc. When applied, the waterproof board provided in the utility model has the advantages of convenient operation, relatively low cost and wide application range.
Description
Technical field
The utility model relates to the waterproof, seepage control technical field, and a kind of tunnel special-purpose water-proof plate is provided especially.
Background technology
Along with modern railways, Freeway Development, the anti-draining in tunnel is more and more important.The basic unit's waterproof that also has highway and railway slope in addition, the isolation of earth rock cofferdam weak soil and piece stone, the processing of impervious barriers such as reservoir dam, river course, gutter, artificial lake; Isolation between refuse landfill, sewage-farm filtrate and the rubbish and antiseepage etc.; These infrastructure construction engineerings all relate to the water proof anti-seepage problem.Use a large amount of common splash guards now on the engineering, perhaps cost is high, and perhaps drainability is poor, and technique effect is limited.
People urgently hope to obtain the better tunnel of a kind of technique effect special-purpose water-proof plate.
The utility model content
The utility model purpose provides the better tunnel of a kind of technique effect special-purpose water-proof plate.
A kind of tunnel of the utility model special-purpose water-proof plate is characterized in that: it is by non-woven geotextile layer 1, gripper shoe 3, splash guard 2; Wherein: gripper shoe 3 is arranged between non-woven geotextile layer 1 and the splash guard 2, the three successively according to layered arrangement and through calendering, heat and, coextru-lamination is integral; Gripper shoe 3 is specially the lamellated plate that is made up of the skeleton fabric.
The said tunnel of the utility model special-purpose water-proof plate requires the following preference of protection:
Above-mentioned splash guard 2 is one of following several kinds: polyvinylchloride splash guard, polythene PE splash guard, high-molecular polythene HDPE splash guard, ethylene-vinyl acetate copolymer EVA splash guard.
Gripper shoe 3 is specially glass wool board;
Non-woven geotextile layer 1 is specially the long filament non-woven geotextile.
The utility model barrier performance is good.Between non-woven geotextile layer 1 and splash guard 2, lay one deck gripper shoe 3, the water that the water guide structure non-woven geotextile layer 1 that forms through gripper shoe 3 leaches is derived and is drained, and has the incomparable anti-seepage effect of common waterproofing materials; Non-woven geotextile layer 1 and the splash guard 2 that adopts is poison ring and protects material, and antiseepage, water conservancy diversion are common physical changes, do not produce any hazardous substances;
The utlity model has excellent mechanical intensity, excellent elasticity and deformability.Physical and mechanical property indexs such as tension, anti tear, the anti-bursting value of CBR, transmission coefficient are apparently higher than common waterproofing materials, and anti-puncture ability is strong, and being applicable to expands shrinks basal plane, can overcome the uneven subsidence of basal plane;
The utility model quality is comparatively 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;
The utility model is easy and simple to handle in application process, and cost is lower, applied range.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is a tunnel special-purpose water-proof plated construction simplified schematic diagram.
The specific embodiment
A kind of tunnel special-purpose water-proof plate, it is by non-woven geotextile layer 1, gripper shoe 3, splash guard 2; Wherein: plate 3 is arranged between non-woven geotextile layer 1 and the splash guard 2, the three successively according to layered arrangement and through calendering, heat and, coextru-lamination is integral; Gripper shoe 3 is specially the lamellated plate that is made up of the skeleton fabric.Wherein: the weight of gripper shoe 3 satisfies every square metre of 250-400 gram, and bed thickness is 2-5mm.Splash guard 2 thickness are 0.5-3mm.Non-woven geotextile layer 1 thickness is 0.3-1.5mm.
Above-mentioned splash guard 2 is polyvinylchloride splash guards.
Gripper shoe 3 is specially glass wool board;
Non-woven geotextile layer 1 is specially the long filament non-woven geotextile.
The present embodiment barrier performance is good.Between non-woven geotextile layer 1 and splash guard 2, lay one deck gripper shoe 3, the water that the water guide structure non-woven geotextile layer 1 that forms through gripper shoe 3 leaches is derived and is drained, and has the incomparable anti-seepage effect of common waterproofing materials; Non-woven geotextile layer 1 and the splash guard 2 that adopts is poison ring and protects material, and antiseepage, water conservancy diversion are common physical changes, do not produce any hazardous substances;
Present embodiment has excellent mechanical intensity, excellent elasticity and deformability.Physical and mechanical property indexs such as tension, anti tear, the anti-bursting value of CBR, transmission coefficient are apparently higher than common waterproofing materials, and anti-puncture ability is strong, and being applicable to expands shrinks basal plane, can overcome the uneven subsidence of basal plane;
The present embodiment quality is comparatively 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;
Present embodiment is easy and simple to handle in application process, and cost is lower, applied range.
Present embodiment content and embodiment 1 are basic identical, and its main difference part is:
Splash guard 2 is polythene PE splash guards.
Gripper shoe 3 is specially the nylon stratum reticulare.
Present embodiment content and embodiment 1 are basic identical, and its main difference part is:
Splash guard 2 is high-molecular polythene HDPE splash guards.
Embodiment 4
Present embodiment content and embodiment 1 are basic identical, and its main difference part is:
