Description
Technical field
The invention belongs to underground engineering processing slurry injection technique field, more particularly to one kind to fill suitable for constructing tunnel goaf
Fill out the new filling paste slurry of processing.
Background technology
Tunnel is built in goaf, the prominent mud of gushing water is often faced with, the risk that face caves in, is brought to building for tunnel
Construction Difficulties.The stratum in goaf loosely, is played pendulum, and tunnel cave is easily caused after tunnel excavation disturbance.Tunnel
Road Overburden gob area easily causes the prominent mud of gushing water or face slump, goaf of underliing then easily cause tunnel and collapsed.At present, slip casting
Filling is the measure in processing goaf widely used in engineering practice.
Carrying out the conventional grouting material of goaf grouting filling treatment in engineering at this stage has：Ordinary cement slurry, cement flour
Coal ash slurries and cement-sodium silicate double liquid etc..Wherein, there is low, water resistant bad dispersibility of slurries calculus rate etc. in ordinary cement slurry
Defect；The early strength of Cement fly ash is relatively low, and the source of flyash is limited；During the condensation of cement-sodium silicate double liquid
Between be difficult to control, slurry filling technique is more complicated, and slip casting effect is had a great influence by construction level.Therefore, one kind is developed to be applied to
The material of goaf filling slip casting turns into this area urgent problem to be solved.
The content of the invention
The technical problems to be solved by the invention are to overcome the shortcomings of to mention in background above technology and defect, there is provided one
Kind calculus rate is high, filling effect is good, green, raw material is cheap and easy to get, setting time is controllable, preparation is convenient and site operation is grasped
Make simply suitable for the new filling paste slurry of constructing tunnel goaf filling processing.
In order to solve the above technical problems, technical scheme proposed by the present invention is：
A kind of filling paste suitable for constructing tunnel goaf is starched, the filling paste slurry mainly by clay magma, cement and
Water is formulated, and the clay magma is mainly formed by clay and water stirring, and modifying agent is added with the filling paste slurry, described
Modifying agent is the meta-aluminate of the cement quality 0.5-1.5% including volume and volume is the cement quality 0.2-0.4%
Lignosulfonates.If meta-aluminate volume is excessive, slurries rate of set is very fast, easy plugging, and concrete castability is poor；If volume
It is too small, do not reach the effect for accelerating slurries to condense.If calcium lignosulfonate volume is excessive, the mobility of slurries is too big, unsuitable
Control.Therefore, preferable effect can be obtained from the volume scope of above-mentioned meta-aluminate and lignosulfonates.
As the further improvement to above-mentioned technical proposal：
Preferably, the mass ratio of the clay magma and cement is (2-3)：1.
It is furthermore preferred that the proportion of the clay magma is 1.20-1.35g/cm3。
It is furthermore preferred that the plasticity index of clay is not less than 14 in the clay magma, particle diameter is less than 0.005mm's in clay
The quantity of clay is no less than 30%.The combination effect of clay and cement is optimal on this condition, and size performance is more preferable.
Preferably, the cement is Portland cement 42.5, the cement by the screen over-size after 80 μm of square hole screens not
More than 5%.
It is furthermore preferred that the mass ratio of the gross mass and water of clay and cement is (0.8-1.5) in the filling paste slurry：1,
The proportion of filling paste slurry is 1.3-1.6g/cm3.Under this match ratio, the basic performance and mechanical property of slurries are optimal.
It is furthermore preferred that the fluidity of the filling paste slurry is 102-150mm.The flowing degrees of data is justified mould by truncated cone and surveyed
, the filling paste slurry as constructing tunnel goaf should have suitable fluidity, if fluidity is too small will to be unfavorable for cream slurry
Perfusion, if fluidity too senior general cause cream slurry diffusion far cause very much to waste, consider, fluidity is between 110-150mm
It is more suitable.
It is furthermore preferred that the presetting period of the filling paste slurry is 5-25min, calculus rate is not less than 95%.Filling paste slurry
Setting time should be moderate, if the presetting period it is too short will be unfavorable for irrigating, and final setting time is oversize, is unfavorable for early strength
Generation.Calculus rate is big, and slurry will not occur to precipitate bleed phenomenon, preferable to the filling effect in goaf.
Preferably, the meta-aluminate is sodium metaaluminate；The lignosulfonates are calcium lignosulfonate.
Preferably, the 28d compression strength after the filling paste slurry condenses is not less than 2MPa.Meet that constructing tunnel goaf is filled out
Processing compression strength requirement is filled, tunnel safety can be made to pass through goaf.
Compared with prior art, the advantage of the invention is that：
(1) filling paste of the invention slurry cost is low, and the prices of raw materials such as cement used, clay are cheap and are easily obtained.
(2) filling paste slurry is prepared convenient and swift, and setting time is controllable, and site construction technology is simple.
(3) filling paste slurry fluidity is moderate, stability is good, calculus rate is high, can meet filling for tunnel goaf well
Fill out processing requirement.
(4) filling paste slurry is green, and environment will not be polluted.
