Description
Technical field
The present invention relates to building waterproofing technique field, more particularly to prefabricated assembled concrete piping lane seam waterproof construction and
Engineering method.
Background technology
Currently, prefabricated assembled concrete piping lane interface waterproof method mainly has 3 kinds：Rubber ring waterproof type, chance water are swollen
Swollen rubber strip waterproof type and composite water-proof mode.It is wedge shape or circle that the first rubber ring waterproof type, which is section configuration,
The rubber ring of shape is fixed on the inclined-plane of socket, and into after bellmouth, gap becomes smaller, and rubber ring is compressed and rebounded, and is against and holds
Socket both sides, block water and pass through.Second of water-swellable adhesive tape mode, is that hydro-expansive rubber item is fixed on box culvert end face, according to
By stressing cable, bolt adjacent box culvert is longitudinally close to, when meeting water, the adhesive tape between box culvert expands, and is against end face
Both sides block water and pass through.The third composite water-proof mode is to integrate rubber ring waterproof and water-swellable adhesive tape, two pass waterproof.
Rubber ring waterproof there are the problem of：In 35mm to 40mm, bell and spigot has prodigious common rubber ring depth of section
Dimensional tolerance (± 2mm), the stress relaxation of rubber itself, elasticity attenuation leads to waterproof failure.(in hydraulic system, rubber ring
Sealing is used widely, and is because being easily controlled by the dimensional tolerance of sealing element) for this purpose, some designs use 2 rubbers
Cushion rubber also has the cement injection fine sand between 2 rubber rings to starch, since thinking is not suited the medicine to the illness, does not solve the problems, such as.
Hydro-expansive rubber there are the problem of：Presently commercially available hydro-expansive rubber is actually to have mediated a large amount of swellings
Soil, referred to as water-swellable putty, in addition to the stress relaxation of itself, except elasticity attenuation, bentonite clay particle is lost in water, is caused
Volume atrophy, cannot long-term waterproof.Certain hydro-expansive rubbers be polyurethane chlorination buna, natural rubber be kneaded after, squeeze
Go out molding, there are the stress relaxation of itself, the problem of elasticity attenuation, some polyurethane is after dry season, volume not reflation.
There is expert advice that original 1 rubber ring is changed to 2 rubber rings；Also the expert advice having uses 2 waterproof measures, uses simultaneously
2 rubber rings and hydro-expansive rubber and caving-in bash, 2 less reliable waterproof measures also do not support altogether together can
The projected life of the waterproof measure leaned on, box culvert is 100 years, and existing waterproof measure is difficult to permanently effective, the leak stopping of underground waterproof
Difficulty is big, and expense is more than ten times of waterproof.
