Description
Technical field
The present invention relates to underground engineering reinforcing soft formation and antiseepage water blockoff slurry injection technique field more particularly to a kind of modifications
Dual-liquid slip-casting material.
Background technique
Slip casting is that certain material is configured to slurries, and being poured into stratum or gap with force feed equipment makes its diffusion, coagulates
Glue or solidification, to achieve the purpose that strengthening stratum or impervious leakage-stopping.Such as geological conditions during the construction of underground tunnel such as subway
Difference, rich groundwater when water level is higher, easily occurs the emergency events such as prominent mud water burst, first branch strain cracking, apply tunnel
There are great security risks for work, to ensure that tunnel excavation face stabilization is not collapsed, need to carry out grouting for water blocking reinforcing to the soil body, reduce
Surface subsidence improves soil sand body self-stability, ensures that bored tunnel normally excavates.The injecting paste material of good durability and working performance
It is the key that reach good slip casting effect, is of great significance to the safety and progress that ensure constructing tunnel.
Using waterglass and curing agent are short and controllable with setting time as the dual-liquid slip-casting material of host agent, calculus rate is high, slurry
The features such as liquid not easily runs off can achieve the purpose of fast blockage, in underground engineering in the biggish stratum of groundwater velocity
It is widely used.But there are still many shortcomings for traditional waterglass class dual-liquid slip-casting material, such as tie solid knot
Structure is unstable, and durability is poor, resists erodible difference.
Summary of the invention
The purpose of the present invention is provide a kind of pair of modification for defect existing for traditional waterglass class dual-liquid slip-casting material
Liquid grout material has many advantages, such as that stability is good, durability is good, set strength is high.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of modified dual-liquid slip-casting material, it is characterized in that, including A liquid and B liquid；
The A liquid is waterglass, and modulus is 2.0~3.5, and Baume degrees is 20~45Be '；The B liquid is modified water
Slurry liquid, by weight group become：500~900 parts of cement, 50~200 parts of zeolite powders, 50~300 parts of slag powders, 0~50
Part phosphoric acid, 1~10 part of naphthalene water reducer, 700~1500 parts of water；In use, A liquid and B liquid are pressed the (volume of 0.5~1.5) ︰ 1
Than uniformly mixing to get to the modification dual-liquid slip-casting material.
Further：
The cement is the ordinary portland cement or early-strength ordinary portland cement that strength grade is not less than 42.5.
The zeolite powder fineness (80 μm of square hole water sieves tail over)≤15%.
The slag powders are ground granulated blast furnace slag, specific surface area >=300m2/kg。
Compared with the prior art, the present invention has the beneficial effect that：
The present invention replaces part of cement to react with waterglass using zeolite powder and slag powders, and zeolite powder has microcosmic more
Pore structure can improve the workability and stability of cement grout, and the water energy of combination is adsorbed in zeolite powder hole in hydration reaction
Later period is released, and keeps knot solid aquation more abundant, improves compactness and intensity.Zeolite powder and slag powders are active silica-alumina
Pozzolanic reaction occurs under alkaline condition for material, can improve the pore structure of knot solid, makes to tie the total porosity drop of solid
Low, average pore size reduces, and pore structure refinement, pore size distribution is more reasonable, and knot solid is finer and close, to keep durability, water resistant molten
Corrosion, compression strength are improved.Phosphoric acid has deferred action, gel time can be controlled at several seconds to dozens of minutes, and
And the stability of cement grout can be improved.Naphthalene water reducer can form adsorption layer in cement particle surface, generate space bit
Resistance reduces internal friction, so as to improve the rheological property of slurries.Each component, which cooperates, in injecting paste material acts synergistically, and produces
Good effect has been given birth to, has made that injecting paste material stability is good, durability is good, set strength is high.
Specific embodiment
Below with reference to embodiment, the invention will be further described.
Examples 1 to 6
The preparation of A liquid：The water glass solution of concentration needed for selecting.The preparation of B liquid：It is measured by required mass parts, first into water
Phosphoric acid, naphthalene water reducer, zeolite powder and slag powders are added, adds cement after mixing evenly, continues to stir evenly.By A
Liquid and B liquid are uniformly mixed by required volume ratio to get the finished product of injecting paste material is arrived.Each group distribution ratio is shown in Table in Examples 1 to 6
1。
Table 1 is modified dual-liquid slip-casting material each group distribution ratio
Correlated performance test is carried out to dual-liquid slip-casting material modified in above-described embodiment 1~6, test result is shown in Table 2.
Table 2 is modified dual-liquid slip-casting material the performance test results
According to above-mentioned test result as it can be seen that injecting paste material of the present invention has stability good (B liquid 2h water absorption rate < 5%), coagulate
The knot time is adjustable, consolidating strength height (7d compression strength > 5MPa, 28d compression strength > 14MPa), and durability is good, and (corrosion is supported
Intensity rate of descent < 30% after shield 180d) outstanding advantages of.
