It is easy, it is quick and easy for installation, shorten the casting cycle of precast beam, it is ensured that draining is unobstructed and traffic safety, extends using the longevity
Life.
The present invention solves technical problem and adopted the following technical scheme that：
A kind of construction technology of high-speed rail bridge tapping pipe, comprises the following steps：
（1）By mould installion corresponding to tapping pipe reserving hole in the fixed template of precast beam combination；
（2）Hole is buried using pvc pipe, it is ensured that embedded hole is vertical, pours into a mould concrete, after health 26~30 days, removes
Tapping pipe hole presetting mold；
（3）Pvc pipe is cut, mounting groove is dug out at the top of bridge floor, tapping pipe is put into hole, tapping pipe is fixedly mounted；Use
Grouting material around sluicing tube wall with mounting groove to blocking；Specifically by water and grouting material according to mass ratio 3~6：1
Mixed slurry is obtained after being mixed evenly, is flowed into by mounting groove in the space between tapping pipe and bridge, mixed slurry is smash
It is real；The grouting material includes the raw material of following parts by weight：50~80 parts of Portland clinker, 20~35 parts of epoxy resin,
10~18 parts of kaolin, 5~12 parts of flyash, 2~6 parts of glass fibre, 0.6~2.5 part of polycarboxylate water-reducer, curing agent 0.5
~2 parts, 0.02~0.06 part of catalyst, 0.05~0.16 part of defoamer；
（4）When the grouting material intensity of closure cast reaches 20~26MPa, building sealant is smeared around tapping pipe is suitable for reading；
The building sealant includes the raw material of following parts by weight：20~40 parts of PPG, phenylethylene-maleic anhydride copolymerization
10~20 parts of thing, 3~8 parts of sodium lignin sulfonate, 1~6 part of paraffin, 3~6 parts of epoxy resin, 1~5 part of aluminium hydroxide, thixotropic agent
0.2~0.6 part, 0.02~0.08 part of age resistor.
Further, the step（1）The size of tapping pipe reserving hole is 280~320 × 300~320mm.
Further, the grouting material includes the raw material of following parts by weight：68 parts of Portland clinker, epoxy resin
28 parts, 15 parts of kaolin, 10 parts of flyash, 5 parts of glass fibre, 1.8 parts of polycarboxylate water-reducer, 0.8 part of curing agent, catalyst
0.03 part, 0.09 part of defoamer.
Further, the curing agent in the grouting material is selected from benzene dimethylamine, diaminodiphenyl-methane, 2- methyl miaows
One or more combinations in azoles, maleic anhydride；Catalyst in the grouting material is selected from sodium butylnaphthalenesulfonate, two
One or more combinations in sodium butylnaphthalenesulfonate, diisobutyl sodium naphthalene sulfonate；Defoamer in the grouting material is selected from
GPE types defoamer or GPES type defoamers.
Further, the building sealant includes the raw material of following parts by weight：32 parts of PPG, styrene-suitable
15 parts of maleic anhydride copolymer, 5 parts of sodium lignin sulfonate, 3 parts of paraffin, 4 parts of epoxy resin, 2 parts of aluminium hydroxide, thixotropic agent
0.3 part, 0.05 part of age resistor.
Further, it is fine to be selected from precipitated silica, organobentonite, ethoxy for the thixotropic agent in the building sealant
One or more combinations in dimension element, age resistor are selected from octylated diphenylamine, N, N ＇-diphenyl-para-phenylene diamine, styrol
One or more combinations in phenol, 2- sulfydryl benzo benzenediols.
Further, the step（3）Consolidated during mixed slurry top surface 3 ~ 8mm lower than tapping pipe top opening.
Further, the step（4）Building sealant needs to install sluicing double-edged fine-toothed comb after smearing solidification.
Compared with prior art, the present invention has the advantages that：
（1）The construction technology of the high-speed rail bridge tapping pipe of the present invention, main embedded, filling including hole mould installion, pvc pipe
