As depicted in figs. 1 and 2, for provided by the invention a kind of in buried can the grouting method of slip casting waterstop, it comprises the steps:
S1, to install at the joints of segment place of adjacent two concrete components buried together can slip casting waterstop 6, buriedly in described the both sides of slip casting waterstop 6 can be respectively equipped with pre-buried type Grouting Pipe, and buriedly in described the many grouting pipe 8 be communicated with described pre-buried type Grouting Pipe 7 can be set respectively for the both sides of slip casting waterstop 6; The method to concrete and waterstop slip casting effect good; The consolidation strength of slip casting is high, can direction and location, and grouting serous fluid all enters seam, and the utilization rate of slurries is high; The method better economy, and construction is also simpler;
S2, particularly, the spacing between adjacent two grouting pipe can be 5-6m;
S3, injecting treatment is made after concrete intensity reaches 45MPa, grouting pipe 8 is one by one adopted to carry out slip casting during slip casting, choose wherein a grouting pipe as the first grouting pipe 1, first from the first grouting pipe 1 slip casting, when second grouting pipe 2 adjacent with described first grouting pipe 1 and the 3rd grouting pipe 3 pulp (or after first grouting pipe 1 pressure to 1MPa), stop slip casting, now close the first grouting pipe 1 with plug, then slip casting from the second grouting pipe 2 and the 3rd grouting pipe 3, after four grouting pipe 4 adjacent with described second grouting pipe 2 and five grouting pipe 5 pulp adjacent with described 3rd grouting pipe 3, plug is utilized to close described second grouting pipe 2 and the 3rd grouting pipe 3, subsequently by that analogy, until after last root grouting pipe pulp, stop slip casting, and close last root grouting pipe.The method adopts circulating mud jacking, can accomplish to fill slurries completely in whole sealing zone circle, and high in conjunction with slurry consolidation intensity, and the feature of good penetrability, perfectly accomplishes the feature of waterproof, sealing.
Wherein, in S3, injecting paste material is modified epoxy grouting liquid, and this material initial viscosity is little, and penetrating power is strong, adhesion strength and compressive strength high, anti-permeability performance is good.Particularly, (1) this material main performance index 1. viscosity: <200mPa.s; 2. the initial setting time: 8 ~ 24 hours; 3. pure colloid compressive strength: >=40MPa; 4. compress variation: 40 ~ 60%; 5. adhesion strength: >2.5MPa.(2) match ratio: Sui Jin section SJK-02 modified epoxy grouting liquid: Sui Jin section SJK-02 modified epoxy grouting liquid is 25:2, grouting pipe preferably settles 24 altogether, and the arrangement distance controlling of each grouting pipe is within the 5-6m scope of code requirement, adopt circulating slip casting one by one, simple to operate.Adopt modified epoxy grouting liquid initial viscosity little, penetrating power is strong, adhesion strength and compressive strength high, the features such as anti-permeability performance is good, can fabulous the coupling together by very trickle gap, and utilize its adhesion strength high feature waterstop and concrete can be combined, play sealing effect.
Wherein, in S3, if centre have indivedual grouting pipe 8 because of blocking cannot pulp time, keep pressure after 10-15 minute, proceed next root grouting pipe 8 slip casting.
Wherein, in S3, the grouting pressure of every root grouting pipe 8 controls between 0.5MPa ~ 1MPa, and the slip casting duration should control at 7 ~ 15 minutes.
Wherein, in S3, the grouting pressure of last root grouting pipe 8 reaches 0.6MPa and keeps pressure preferably within 5 minutes, can stop slip casting without when obviously reducing in 3-5 minute.If grout outlet does not flow out slurries smoothly, grouting pressure can be strengthened, but pressure should not more than 1MPa.After whole grouting completes, according to drawing the liquid level height exposing conduit slurries, determine whether to need back-grouting.
Wherein, in S1, be also provided with rubber strip 9 at the joints of segment place of adjacent two concrete components, it is inflatable that described rubber strip 9 meets water, thus when slurries are noted in seam, described rubber strip 9 preferably by joint sealing, thus can play good hermetic seal effect after expanding.
Slip casting effect of the present invention is good, and the utilization rate of slurries is high; And better economy, construct also simpler.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
