It seeps.Currently used mainly ECB single ply waterproofing web construction, splash guard construction is mainly using empty laid process construction, tunnel, underground
Room has the engineering bottom plate of concrete bed course to be laid with using empty laid process, and side wall, arch crown part are fixedly mounted using gasket method, by special-purpose cushion
Piece is fixed in base with nailing, then splash guard is welded in special washer, and overlap joint uses hot air welding.
Due to ECB waterproof roll, it is mainly used for underground, is typically designed to single layer structure, uses as main water barrier.ECB
The flexibility of waterproof roll is good, but lower to its tensile property and tear resistance design requirement.Although coiled material design in underground, by
The opposite exposed material influence of the influence meeting of ultraviolet light or outdoor normal environment is small, but under long-term moist environment, also can
Cause its tensile property and tear resistance to decline, eventually leads to the reduction of its service life, influence the using effect of material.
Utility model content
To overcome above-mentioned technical problem, the utility model provides a kind of ECB composite of water-proof coiled material structure, its entirety can be improved
The physical property and integral waterproofing effect of material.
The utility model takes following technical scheme:
A kind of ECB composite of water-proof coiled material structure, including HDPE layer, the HDPE layer upper and lower surface have been covered each by one layer
ECB layers, two layers of ECB layers of another side has been covered each by one layer of enhancement layer, and the enhancement layer is EVA, TPE, TPV, TPO
Or one of TPR material.
Preferably, the HDPE layer with a thickness of 0.3 ~ 0.6mm.
Preferably, described ECB layers with a thickness of 0.6 ~ 1.0mm.
Preferably, the enhancement layer with a thickness of 0.25 ~ 0.55mm.
Preferably, the another side of two layers of enhancement layer is covered each by matcoveredn, and the protective layer is woven dacron, poly- second
One of allyl synthetic fibre or geotextiles.Woven dacron, polyethylene polypropylene or geotextiles have excellent wrinkle resistance and conformality, have
Higher intensity and elastic recovery capability play the work of protection so that material is not easy to deform in a humidity environment, tears
With.
Preferably, the protective layer with a thickness of 1.8 ~ 2.6mm.
Preferably, the another side of two layers of enhancement layer has been covered each by atactic polypropylene (APP) modified bituminous layer.Plastomer modified drip
Cyan layer makes whole composite sheet material have self-adhesion function, uses and constructs and is more convenient.
Compared with prior art, the utility model has the beneficial effects that HDPE material has excellent tensile property and resists
Lancinating, but flexibility is poor, the flexibility of ECB material is good, but tensile property and tear resistance do not have that HDPE material is good,
HDPE layer upper and lower surface has been covered each by one layer ECB layers, combines the two and mutually makes up, and can effectively improve waterproof roll entirety
The physical properties such as stretching, tear-proof and flexibility improve waterproof effect；Enhancement layer has the performances such as protection, waterproof, stretchable,
So that coiled material, which integrally has, is able to maintain higher elongation percentage while sufficient intensity, such as EVA, TPE, TPV, TPO or TPR material again
Material etc. is able to satisfy requirement, and selection multiplicity to improve the physical property of integral material, keeps the comprehensive performance of material best,
Increase the waterproof time limit, it is easy for construction simple, it is pollution-free.
