Description
Technical field
The utility model relates to a kind of grouting device, particularly a kind of shield structure biliquid slurry filling adaptor.
Background technology
Along with China's expanding economy, city track traffic engineering is all being built in each main cities, the interval shield constructions that adopt more, and shield structure secondary grouting adopts biliquid slurry, and biliquid slurry grouting process is complicated, and liquid slurry is short time of setting, often causes line clogging; My company No. 4 line first stage of the project civil engineerings of Chengdu subway 7 bid section province Federation of Literary and Art Circles station~beautiful two-way station shield structures of being responsible for constructing are interval, left line total length 990.637m, right line total length 1310.134m, cutter head of shield machine diameter 6280mm, section of jurisdiction external diameter 6000mm, after pipe sheet assembling is complete, deviate from shield tail, radial clearance together with section of jurisdiction forms with between the soil body; Sand-pebble layer is under groundwater effect simultaneously, and rock mass is loose, and without cementing, self-stability is poor, and during cutterhead rotary cutting, stratum is easy to destroy original relatively stable or equilibrium state, causes larger Stratum Loss self-stability and poor, after disturbance, very easily caves in; Shield structure hole employing synchronous grouting is filled, and slurries adopt single liquid slurry, and single liquid slurry setting time is long, in rich water sand-pebble layer, lose greatly, and effectively filling pore and fixedly section of jurisdiction, single liquid slurry intensity is low, is unfavorable for tunnel duct piece stable and antiseepage in early days.For making up the deficiency of synchronous grouting, generally again carry out secondary grouting filling, slurries adopt single liquid slurry and biliquid slurry, and single liquid slurry adopts water mud, and single liquid slurry is simple to operate, and the initial setting time is long, the stable and antiseepage of unfavorable section of jurisdiction; Biliquid slurry is mixed by neat slurry and water glass, and biliquid slurry is short time of setting, and intensity is high, can effectively stablize section of jurisdiction, prevents section of jurisdiction seepage, and the slip casting of single biliquid slurry is complicated, in note biliquid slurry process, easily causes pipeline blockage, clears up cumbersome.。
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the shortcoming of above-mentioned background technology, provides a kind of and can effectively fill the hole between section of jurisdiction and the soil body, and good ground, settlement prevention can also effectively shorten the shield structure biliquid slurry filling adaptor that biliquid slurry mixes distance.
The technical solution of the utility model is: a kind of shield structure biliquid slurry filling adaptor, described shield structure biliquid slurry filling adaptor comprises: ball valve, internal thread tee piece, one way valve, relief valve, section of jurisdiction connector, socket I, socket II, hollow tee piece, described internal thread tee piece left side is provided with ball valve, this ball valve connects cement paste Grouting Pipe, described internal thread tee piece connects hollow tee piece by socket I, described hollow tee piece right side is connected with section of jurisdiction connector, described hollow tee piece top is provided with socket II, socket II is provided with for controlling the one way valve of injected water glass interface, water glass pipe is connected with one way valve, by hollow tee piece to injected water glass in the connector of section of jurisdiction.
Described internal thread tee piece below is provided with relief valve.In slip casting process, cement paste grouting pressure generally reaches 0.5MPa, and instantaneous pressure is larger sometimes, while preventing from dismantling pipeline, hurts sb.'s feelings, and can lay down grouting pressure by the relief valve on side, has guaranteed operating personnel's safety.
Described hollow tee piece length is 89mm, and external diameter is 70mm, and internal diameter is 32mm, and described hollow tee piece side face drilling diameter 15mm hole communicates with inner tube, the socket II of outside welding DN15, height 18mm; The socket I of described hollow tee piece one end welding DN25, length is 20mm, the section of jurisdiction connector of other end welding hollow, length is 79mm.
The beneficial effects of the utility model are: adopt this filling adaptor, can effectively fill the hole between section of jurisdiction and the soil body, good ground, settlement prevention can also effectively shorten biliquid slurry and mix distance, two kinds of slurries are mixed fast, uniformly, make slurries mix and solidify after the wall of section of jurisdiction, avoid slurries frozen plug pipeline in pipeline, thereby improve biliquid slurry slip casting effect, increase work efficiency.
