Description
Technical field
The present invention relates to a kind of injecting paste material, and in particular to is applied to low strength stratum shield duct piece grouting behind shaft or drift lining to one kind
Slurries.
Background technology
After shield machine propulsion, because groundwater resources are abundant, occurs larger space between section of jurisdiction and hole body, if filling is not
In time, the stress on stratum is released, so as to cause hole body deformation.The result is that occur surface subsidence, neighbouring buildings or structures
Sedimentation, deformation or destruction etc..In order to ensure that shield machine is constructed safely, successfully in low-intensity red beds stratum, applied in shield method
Synchronous grouting and secondary grouting are implemented in work, low-intensity red beds stratum is solved with this and meets the problem of water easily softens.Slip casting
Main purpose is to prevent stratum deformation.Secondly, moreover it is possible to suppress the relaxation of DRIFT AND SEPARATION-PILE, prevent stratum deformation；Make pipe early
Loop is stabilized, and jack thrust is smoothly transmitted to stratum；The soil pressure for acting on section of jurisdiction is set averagely to disperse, reduction acts on pipe
The stress and segment deformation of piece, the direction of shield are easier control；And form effective waterproof layer.Slip casting slurry of the prior art
Liquid poor fluidity, gelling time is long.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of slurry suitable for low strength stratum shield duct piece grouting behind shaft or drift lining
Liquid, improves the mobility of shield duct piece grouting behind shaft or drift lining slurries, shortens gelling time.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of slurries suitable for low strength stratum shield duct piece grouting behind shaft or drift lining, include the slurries and secondary injection of synchronous grouting
The slurries of slurry,
The Mortar mix proportion (mass ratio) of the synchronous grouting is：
Cement：Sand：Water：Flyash：Bentonite=160:830:450:400:50；
The Mortar mix proportion (mass ratio) of the secondary grouting is：
Cement：Water：Waterglass=445:356:685.
According to such scheme, the sand in the slurries of the synchronous grouting is the fine sand that modulus of fineness is 1.66~2.3.
According to such scheme, the flyash in the slurries of the synchronous grouting is II grades of flyash of F classes.
According to such scheme, the bentonite in the slurries of the synchronous grouting is calcium-base bentonite.
According to such scheme, the waterglass in the slurries of the secondary grouting is I class waterglass.
Compared with prior art, the beneficial effects of the invention are as follows：The slurries of synchronous grouting of the present invention have calculus
The features such as durability that rate is high, consolidating strength is high, good, prevent in synchronous grouting, washing away and leach due to underground water
The invalid slip casting caused.The slurries of secondary grouting of the present invention overcome the setting time length of single liquid cement mortar and are difficult to control
The low shortcoming of calculus rate under system, river channels, improves the effect of cement injection, expands the scope of cement injection, it is to avoid
Ordinary cement slurry slip casting effect is bad, multiple slip casting, so that wasting situation.
Embodiment
It is most after shield machine driving it is an object of the invention to carrying out slip casting after the shield duct piece wall of low-intensity red beds stratum
Early filling stratum, reduces subsidence of foundations amount, it is ensured that the security of surrounding environment；Ensure early stage stability and the gap of pipe-plate lining
Density；As the first line of defence of lining waterproof, there is provided long-term, homogeneous, stable water-proof function；It is used as tunnel-liner knot
The enhancement layer of structure, makes it have durability and certain intensity.
The general requirement of synchronous grouting is：
1. gelling time:Generally 3~10h.According to formation condition and driving speed, coagulant is added by field test
And change matches to adjust gelling time., can for highly permeable stratum and the location for needing slip casting to provide higher early strength
Proportioning is further adjusted by field test and early strength agent is added, further shortens gelling time.
2. concretion body strength:It is not less than within one day 0.2MPa, is not less than 2.5MPa within 28 days.
3. slurries calculus rate:>95%, that is, consolidate shrinkage factor<5%.
4. slurry consistency:8~12cm.
5. pulp stability:Decantation rate (the ratio between floating water volume and cumulative volume after staticly settling) is less than 5%.
The Mortar mix proportion (mass ratio) of the synchronous grouting used in common engineering for：
Cement：Sand：Water：Flyash：Bentonite=210:1180:294:315:84.
When its water-cement ratio is 0.48, slurry consistency about 8cm, gelling time about 6h.Although construction can be met, with regard to data
From the point of view of slurry consistency it is relatively low, gelling time is too short, but its Strength surplus coefficient is higher.For low-intensity red beds stratum difficulty of construction
Greatly, field control is not easy to, higher surplus strength also result in unnecessary waste.
The Mortar mix proportion (mass ratio) of neoteric synchronous grouting is：
Cement：Sand：Water：Flyash：Bentonite=160:830:450:400:50.
When its water-cement ratio is 0.73, slurry consistency about 11cm, gelling time about 8h improve fluidity and gelling time,
Its enough Strength surplus coefficient is also ensure that, can preferably be applied to low-intensity red beds stratum.
The characteristics of chance water easily softens is had according to low-intensity red beds stratum, the slurries of neoteric synchronous grouting with the addition of swelling
The material such as soil and flyash, makes the features such as slurries have the durability that calculus rate is high, consolidating strength is high, good, prevents same
Walk in slip casting, washing away and leach the invalid slip casting caused due to underground water.Used cement is P.O42.5 normal silicates
Cement.Used sand is the fine sand that modulus of fineness is 1.66~2.3, does not allow the rubble or debris for being mingled with more than 5mm, must
When wanting sieving processing need to be carried out to sand.Used flyash is II grades of flyash of F classes, and used bentonite is that calcium base is swollen
Profit soil, used drinking water is drinkable water.
The general requirement of secondary grouting is：
1. the grouting pressure of cement mortar：0.2MPa~0.4Mpa.
2. slurry flow：10~15L/min.
3. the grouting pressure of pair slurries：0.3MPa~0.6Mpa.
The Mortar mix proportion (mass ratio) for the secondary grouting that common engineering kind is used for：
Cement：Water=560:875.
The Mortar mix proportion (mass ratio) of neoteric secondary grouting is：
Cement：Water：Waterglass=445:356:685.
The slurries of neoteric secondary grouting can be along the more uniform seepage flow of section of jurisdiction outer wall, and will not cleave the soil body, the group of being formed
Shape stabilization zone；In order to not influence slip casting effect, general every 5 ring of secondary grouting is noted once, to be formed with a range of hoop, from
And limit the deformation and sedimentation in tunnel.Slip casting hole position is the centre bore of support block and contiguous block, and long interval is such as adjacent block slip casting
When hole is sealed, then in next ring slip casting；It is particularly suitable for use in the low-intensity red beds stratum for meeting water easily soft characteristic.
The raw material selection of secondary grouting is cement, water and waterglass, and slurries are made into by a certain percentage as secondary injection
The slurries of slurry, also referred to as double slurries, this slurries overcome the setting time length of single liquid cement mortar and be difficult to control to, river channels
The lower low shortcoming of calculus rate, improve the effect of cement injection, expand the scope of cement injection, it is to avoid ordinary cement slurry note
Starch effect bad, multiple slip casting, so that wasting situation.Cement used is P.O42.5 Portland cements, is made
Waterglass is I class waterglass, and used water is drinkable water.
