Description
Technical field
The present invention relates to constructing tunnel, a kind of dual-fluid synchronous slip casting block and its construction method are particularly related to.
Background technique
Shield machine is usually used in metro tunnel excavation, and critically important one is exactly to sedimentation, pipe sheet assembling in construction reference
The control of quality.In prior art construction means, how to fill in time, consolidate section of jurisdiction and excavate the gap between the soil body, be
Key point in shield machine development process.
The most effective measure of filling in section of jurisdiction behind gap is that it is synchronous may further to be subdivided into biliquid using synchronous grouting
Slip casting and single liquid synchronous grouting.Synchronous slurry designs main points include preventing from causing to fill not full, section of jurisdiction because slurries are lost
Float, etc..For dual-fluid synchronous slip casting relative to the latter, the presetting period is short, is not easy to plug, and is capable of the sky of Fast Filling section of jurisdiction behind
Gap, but disadvantage is that structure is complicated, volume is big, and needs matched cleaning device, will increase equipment cost and grouting amount.
In the selection of grouting program, the factors such as construction cost, use habit are comprehensively considered, domestic more options list liquid is synchronous
Slip casting+biliquid second pulp feeding (as shown in Figure 8), external more options dual-fluid synchronous slip casting.It is domestic with the development that shield machine is applied
It is more and more vigorous using the demand of dual-fluid synchronous slip casting, and the mode of single liquid synchronous grouting+biliquid second pulp feeding domestic now is
It is unable to meet demand, need to further be improved.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor
Embodiment shall fall within the protection scope of the present invention.
As illustrated in fig. 1 and 2, a kind of dual-fluid synchronous slip casting block, including slip casting block 1, slip casting block 1 is interior to be equipped with channel I7 and channel
The exit of II8, the channel I7 are equipped with flow velocity increasing device, the exit of reverse-osmosis-prevention device II, channel II8 are equipped with anti-return
Seep device I.
As shown in Fig. 3 to 6, it includes gasket ring 2 that the flow velocity, which increases device, and reverse-osmosis-prevention device II includes rubber pad 3, gasket ring
The section of 2 inner holes is less than the section of channel I7, can increase flow velocity, is set on gasket ring 2 there are three inner hole, gasket ring 2 is equipped with rubber
Pad 3, rubber pad 3 include three Rubber ends, and Rubber end and inner hole correspond, and it is logical that the section of Rubber end intake channel is greater than outlet
The section in road, intake channel gradually transit to exit passageway, and the section of exit passageway is cross or linear type, cross or one
Font is gradually raised away from the plane of slip casting block, and rubber pad 3 further decreases section on the basis of gasket ring 2, increases outlet stream
Speed, while can prevent bulk dregs from returning infiltration, gasket ring 2 and rubber pad 3 and be fixed on slip casting block 1 by bolt, connection ring 4, rubber
Rubber mat 3 is between gasket ring 2 and connection ring 4.
The reverse-osmosis-prevention device I includes check valve 6, and the section of check valve 6 is less than the section of channel II8, on check valve 6
Equipped with protective case 5,6 section of check valve is small can to prevent slurries reverse osmosis, and further increases B flow velocity, and protective case 5 can be protected
Impact failure of the check valve 6 by foreign matter is protected, protective case 5 and check valve 6 are bolted on slip casting block 1.
For example retrofitting of used machine, since most old machine is single liquid synchronous grouting, only including A liquid channel and A liquid alternate channel, then
The channel I7 is A liquid channel, and A liquid channel is connected to A flow container, and channel II8 is A liquid alternate channel, A liquid alternate channel difference
It is connected to A flow container, B flow container.
For example new mechanism is made, then is equipped with channel III on the slip casting block 1, and channel I7 is A liquid channel, A liquid channel with
The connection of A flow container, channel II8 are B liquid channel, and B liquid channel is connected to B flow container, and channel III is A liquid alternate channel, and A liquid is spare logical
Road is connected to A flow container.When A liquid channel encounters the situation that can not be dredged, may be selected the alternate channel continue inject single slurry or
Person's dual slurry avoids shield machine because that can not stop tunneling due to slip casting.
As shown in fig. 7, a kind of construction method of above-mentioned dual-fluid synchronous slip casting block, including following mode: two fluid grouting mode,
The A liquid sucked from A flow container enters channel I7, and the B liquid sucked from B flow container enters channel II8, and A liquid, B liquid are added by flow velocity respectively
Big device, reverse-osmosis-prevention device I increase flow velocity, and with form pressure difference in channel, A liquid and the quick of B liquid mix after spraying channel
It closes, realizes two fluid grouting, A liquid, B liquid proportional are changed by the adjusting of the flow of respective plunger pump, can be with after slip casting
Clear water is drawn respectively, cleans entire pipeline.When pipeline blockage, it can be dredged using high pressure water, drill rod；Single fluid grouting mould
Formula, the A liquid sucked from A flow container enter channel I7, carry out single fluid grouting, enter channel II8 from B flow container sucking clear water, with low stream
Amount prevents reverse-osmosis-prevention device I from being blocked by mortar or wearing that (this method is that have " single liquid synchronous grouting+bis- using as shown in Figure 8
It is realized when the retrofitting of used machine of liquid second pulp feeding " equipment).
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
