Description
Technical field
The present invention relates to a kind of slurry shield discarded slurry field, is exactly that a kind of major diameter slurry shield discarded slurry recycles synchronous slip casting.
Background technology
In slurry shield process, produce a large amount of discarded slurries, discarded slurry re-injection after processing, to underground, in the work progress in tunnel, makes full use of discarded slurry, for reducing financial cost, reduces discharge environmental protection important in inhibiting. At present, bentonite clay particle disperses to form suspension in water, has good pulping, and expensive use amount is large, and financial cost is high. Cement adding amount is little, if recruitment is too much, easily cause setting time short, pipe in flow not smooth problem, sand skewness, easily causes lamination; Mud easily water suction too much expands, and causes to transport middlely by pipeline protuberance cracking, and security is lower.
Summary of the invention
The object of this invention is to provide a kind of major diameter slurry shield discarded slurry and recycle synchronous slip casting, there is cheap, setting time of long, mobility advantages of higher.
The present invention for achieving the above object, be achieved through the following technical solutions: major diameter slurry shield discarded slurry recycles synchronous slip casting, prepare every cubic metre of product and comprise following weight raw material: cement 100-180kg, calcium hydroxide 50-120kg, flyash 120-350kg, sand 1300-1500kg, discarded slurry 500-800kg, water-retaining admixture 0.5-2kg, water reducer 0.5-2kg, set retarder 0.5-2kg, air entraining agent 0.5-2kg.
The following particle of 0.075mm of described discarded slurry particle is that the following particle of 99.6%, 0.005mm is 44%, and proportion is 1.15～1.45.
Described water-retaining admixture is methylcellulose, hydroxypropyl methyl fiber or mortar densification powder.
Described water reducer is lignosulfonates, casein or powder polycarboxylate.
Described set retarder is wooden sodium, natrium citricum or sodium pyrophosphate.
Described air entraining agent is colophonium pyrolytic polymer, alkylsulfonate or sodium alkyl sulfate.
Prepare every cubic metre of product and comprise following weight raw material: cement 180kg, calcium hydroxide 50kg, flyash 265kg, sand 1300kg, discarded slurry 500kg, methylcellulose 1kg, lignosulfonates 2kg, wooden sodium 1.5kg, colophonium pyrolytic polymer 0.5kg.
Prepare every cubic metre of product and comprise following weight raw material: cement 100kg, calcium hydroxide 95kg, flyash 180kg, sand 1500kg, discarded slurry 570kg, hydroxypropyl methyl fiber 0.5kg, casein 1kg, natrium citricum 2kg, alkylsulfonate 1.5kg.
Prepare every cubic metre of product and comprise following weight raw material: cement 160kg, calcium hydroxide 70kg, flyash 285kg, sand 1350kg, discarded slurry 530kg, mortar densification powder 1.5kg, powder polycarboxylate 0.5kg, sodium pyrophosphate 1kg, sodium alkyl sulfate 2kg.

The invention has the advantages that: the present invention is without adding expensive bentonite, every side's mortar is saved bentonite 100kg left and right, effectively reduce costs, the present invention has that pump-conveying property is good, water-retaining property, lubricity, mobility and the advantage such as filling is good, and discarded slurry is made full use of. Cheap cement, addition increases, and extends setting time, can not condense in long-time, in way train smoothness, is difficult for plugging, and water retentivity of mortar is better. Sand can be dispersed in slip casting, and water-retaining property improves, and mortar there will not be lamination. Calcium hydroxide water absorbing capacity reduces, and avoids absorbing water too much expanding, and expansion can cause the protuberance cracking of transport pipeline, reduces potential safety hazard. The present invention has peptizaiton to cement, can improve cement mixture mobility, reduces water consumption, improves the workability of mortar, the impervious and corrosion resistance of energy reinforced mortar; Regulate mortar coagulation time, regulate, control water retentivity of mortar, make mortar within the required time period, keep good mobility and pumpability; Improve the workability of Mortar mix, reduce segregation, the bleeding of mixture, improve impermeability and frost resistance. After the present invention sclerosis, there is the effects such as freeze proof, diminishing, antiseepage, durable, cracking resistance.
