Description
Technical field
This utility model belong to building sealing waterproofing work technology, be related to a kind of back sticking type in buried CPE plastics sealing
The preparation of band and construction technology, are mainly used in the engineerings such as vcehicular tunnel, railway tunnel, subway, civil air defense constructions and installations, hypogee
In, play sealing waterproof action
Background technology
Waterstop encapsulant should have preferable caking property, elasticity and ageing resistance, undergo for a long time to stretch and vibrate tired
Labor etc., remains to keep good waterproof effect.Waterstop encapsulant should meet following performance requirement：
(1) there is good pliability, adapt to seam displacement and keep the deflection of effectively sealing；
(2) bond damage and cohesional failure are not produced in seam displacement process.Waterstop can be divided into according to material at present：Rubber
Glue waterstop, plastics waterstop.Waterstop is widely used in various types of xoncrete structures, for example checkdam, cistern,
In the underground engineerings such as subway, culvert, tunnel.In some architectural engineerings, due to being unable to continuous placing, or due to the change of ground
Shape, or the reason such as expand with heat and contract with cold of the concrete component caused due to temperature change, cause pour leave often movement joint,
Construction joint, and these movement joints, construction joint would generally cause structural leakage, in order to prevent because of construction joint, deformation joint seepage, at this
Position uses waterstop encapsulant.
(3) rubber fastening band is present in causing work progress viscous with waterstop joint area because scene overlap joint is complex
The problems such as connecing loosely, causes water seepage.
The failure of waterstop encapsulant has very big relation with the material of waterstop itself, structure type.Main cause
Have：(1) weatherability of waterstop, ageing-resistant performance are poor, cause seal failure；(2) between waterstop and works " three seams "
There is bonding, occlusion, under external environment and external force effect, easily cause seal failure；(3) works are outside
Under the effect such as boundary's circumstance of temperature difference, settlement, distortion, the deformation of waterstop are caused, so as to fail.
At present, in the engineerings such as vcehicular tunnel, railway tunnel, subway, civil air defense constructions and installations, hypogee, in order to prevent water from oozing
Leakage, generally using rubber fastening band and plastics waterstop.And because two kinds of different materials of waterstop are caused and each used
During different degrees of defect.Rubber fastening band has good elasticity and pliability, preferably can be engaged with concrete, more
The micro-deformation of good adaptation concrete, plays sealed waterproof effect, but, the ageing resistace of rubber fastening band is poor, makes
It is short into its service life, have impact on itself excellent sealing, water resistance.And plastics waterstop has excellent weatherability
And corrosion resistance, but the material hardness of itself is higher, it is impossible to well adapt to the micro-deformation of concrete, sealed waterproof effect
It is relatively poor.
