Abstract
The invention provides a fine sand grouting material for ice-rich soil. The grouting material is characterized by taking C3S-C2S--CaO as an essential mineral clinker, grinding C3S-C2S--CaO, gypsum and industrial tailings jointly to prepare a master batch of a cementing material, then adding fine sand or tailing sand with a grain size of 6-10mu m, adding water and stirring the mixtures, thus preparing the grouting material. The grouting material has the beneficial effects that the grouting material is prepared by taking C3S-C2S--CaO as the essential mineral clinker; the mortar fluidity is generally controlled around 400mm; the setting time is 30-60 minutes; the strength of a composite soil layer varies between 0.2MPa and 2.5MPa with variation of the grout amount between 3% and 20%; and the grouting material is especially suitable for fracturing grouting of permafrost with low sand contents so as to prevent soil layer collapse and perform stabilization pre-treatment.
Description
Technical field
The present invention relates to a kind of building cementing material, specifically the rich ice of a kind of fine sand type soil property injecting paste material.
Background technology
Traditional winter executes spraying technique and often adopts OPC cement to add frostproofer, air entrapment agent, accelerating chemicals etc. to reach and reduce the liquid phase freezing point temperature, shorten time of coagulation, improve freezing tolerance and obtain early strength, but in the situation that-30 ℃ of very low temperature, because the hydration and hardening of Portland cement is slow, resist the ability extreme difference of very low temperature freeze injury, must add a large amount of antifreeze air entrapment agents, antifreeze and do not strengthen, fast solidifying and unhappy hard, the concrete bubble is many, impervious poor, therefore concrete later strength and weather resistance decrease.Normal occur cracking, crisp broken, peel off, emit water, seepage, extension ice, the tunnel defects such as moist, greatly affect construction quality.
For example: under central development of the West Regions decision-making, large quantities of engineering projects enter western part.Highway, railway, bridge, riverbed, hillside all need to build to be administered.The state key project financing the Qinghai-Tibet Railway need pass through 547 kilometers eternal frozen ground locations for many years, the Frozen Earth Railway Roadbed that dewaters is solidified, the broken section of the nearly 5000m of height above sea level along the line, weathered rock formation, richness (satisfy) ice soil property, landslide etc. all need outside supporting processes, the urgent need very low temperature slip casting of water frozen soil layer tunnel, injection that two total lengths are 3024 meters.Yet traditional material and Dong Shi technology can not meet the construction requirement of severe cold area fully, such as tooth timberline, tender timberline, the weak line in south etc., permafrost soil layer, Nan Han tunnel are due to the weather severe cold, general cracking in tunnel, crisp broken, peel off, hang ice, emit water, ponding, the tunnel defect such as icing, serious threat owner of a trading company or a workshop safety and work-ing life, maintenance work is heavy, administers very difficult.This is mainly because temperature is low, and the concrete Microstructure Fracture, due to infiltration, Chen Rong vicious cycle etc.
Summary of the invention
The purpose of this invention is to provide the rich ice of a kind of fine sand type soil property injecting paste material, be particularly suitable for sand content low use the frozen soil layer fracture grouting, prevent that soil layer from subsiding and reinforcing pre-treatment.
