Abstract
The invention relates to a technology for grouting a karst subgrade of a high-speed railway, in particular to high-performance grouting slurry for the karst subgrade of the high-speed railway. The invention solves the problems that the shrinkage rate is relatively high, the sufficient filling cannot be realized and the cost is relatively high because the conventional parameters of grouting slurry are unreasonable. The high-performance grouting slurry for the karst subgrade of the high-speed railway is prepared from the following raw materials in part by mass: 100 parts of cement, 86 parts of water, 43 parts of fly ash, less than or equal to 43 parts of sand, and less than or equal to 6 parts of sodium silicate. By testing components and mixing ratio of the grouting slurry for multiple times, the following conclusion is drawn: compared with pure cement slurry, the high-performance grouting slurry for the karst subgrade of the high-speed railway has the advantages that: the cost is greatly saved, the solidification shrinkage rate of the slurry is low, dissolution cavities can be basically filled, the filling rate reaches over 90 percent, the stone formation rate reaches over 80 percent, and the level of strengthening construction of karst subgrades of high-speed railways in China is further improved.
Description
Technical field
The present invention relates to high-speed railway karst roadbed slurry injection technique, be specially a kind of high-speed railway karst roadbed high-performance grouting serous fluid.
Summary of the invention
Along with improving constantly of China Express Railway subgrade construction technology; In roadbed substrate strengthening construction; Grouting serous fluid is to be that water and the cement of 0.8:1 stirs and forms by ratio of weight and number, and slip casting accomplishes that to solidify post-shrinkage ratio big, and molten chamber can not fully be filled; And plain cement slurries cost is high, is unfavorable for grouting quality control and cost control.
Summary of the invention
The present invention can not fully fill more greatly and the cost problem of higher in order to solve the existing unreasonable shrinking percentage that causes of grouting serous fluid parameter, and a kind of high-speed railway karst roadbed high-performance grouting serous fluid is provided.
The present invention adopts following technical scheme to realize: high-speed railway karst roadbed high-performance grouting serous fluid is to be processed by the raw material of following mass fraction: 100 parts of cement, 86 parts in water, 43 parts in flyash, sand≤43 part, water glass≤6 part.
The composition of this grouting serous fluid is the parameter of confirming through a large amount of tests, adds sand, water, cement, flyash stirring in the slurries whipping process successively, treats that the grouting serous fluid use adds the water glass stirring before half a hour and gets final product.
High-speed railway karst roadbed high-performance grouting serous fluid is to be processed by the raw material of following mass fraction: 100 parts of cement, 86 parts in water, 43 parts in flyash.
The composition of this grouting serous fluid is the parameter of confirming through a large amount of tests, is used for high-speed railway filling-type Karst cave karst roadbed and the dead front type solution cavity karst roadbed of height smaller or equal to 1 meter.
High-speed railway karst roadbed high-performance grouting serous fluid is to be processed by the raw material of following mass fraction: 100 parts of cement, 86 parts in water, 43 parts in flyash, sand 1-43 part.
The composition of this grouting serous fluid is the parameter of confirming through a large amount of tests, is used for the high-speed railway height greater than 1 meter dead front type solution cavity karst roadbed.
High-speed railway karst roadbed high-performance grouting serous fluid is to be processed by the raw material of following mass fraction: 100 parts of cement, 86 parts in water, 43 parts in flyash, water glass 1-6 part.
The composition of this grouting serous fluid is the parameter of confirming through a large amount of tests, is used for the high-speed railway height smaller or equal to UNICOM's type solution cavity karst roadbed of 1 meter.
High-speed railway karst roadbed high-performance grouting serous fluid is to be processed by the raw material of following mass fraction: 100 parts of cement, 86 parts in water, 43 parts in flyash, sand 1-43 part, water glass 1-6 part.
The composition of this grouting serous fluid is the parameter of confirming through a large amount of tests, is used for the high-speed railway height greater than UNICOM's type solution cavity karst roadbed of 1 meter.
The present invention draws through the component of grouting serous fluid and proportioning are carried out test of many times; Compare with the plain cement thin pulp, practiced thrift cost greatly, the slurries solidification shrinkage rate is little; Molten chamber can be filled basically; Filling ratio reaches more than 90%, and the calculus rate reaches more than 80%, has further improved China Express Railway karst subgrade strengthening construction level.
