Abstract
Fine sand type ice-rich soil grouting material prepared from C3S-C2S--CaO is used as main mineral clinker, gypsum and industrial tailings are ground together to prepare cementing materialAdding fine sand or tailing sand with the grain diameter of 6-10 mu m into the master batch, and adding water and stirring. The beneficial effects of the invention are as follows: the fine sand ice-rich soil grouting material adopts C3S-C2S-
Description
Technical field
The present invention relates to a kind of building cementing material, specifically a kind of fine sand type rich ice soil property injecting paste material.
Background technology
Traditional winter executes spraying technique and often adopts OPC cement to add antifreezing agent, air entraining agent, accelerator etc. to reach and reduce liquid phase freezing point temperature, shorten setting time, improve freezing tolerance and obtain early strength, but when-30 DEG C of ultralow temperature, because the hydration and hardening of ordinary cement is slow, resist the ability extreme difference of ultralow temperature freeze injury, a large amount of antifreeze air entraining agent must be added, antifreeze and do not strengthen, soon solidifying and unhappy firmly, many, the impervious differences of concrete bubble, therefore concrete later strength and durability significantly reduce.Normal appearance cracking, crisp broken, peel off, the tunnel defect such as Mao Shui, seepage, extension ice, humidity, extreme influence construction quality.
Such as: under central development of the West Regions decision-making, large quantities of engineering project enters western part.Highway, railway, bridge, riverbed, hillside all need to build to be administered.State key project financing the Qinghai-Tibet Railway need pass through 547 kilometers of permafrost soil locations for many years, the Frozen Earth Railway Roadbed that dewaters is solidified, the nearly 5000m of height above sea level along the line broken section, weathered rock formation, richness (satisfy) ice soil property, landslide etc. all need outside supporting process, the water frozen soil layer tunnel urgent need ultralow temperature slip casting of two total lengths 3024 meters, injection.But traditional material and Dong Shi technology can not meet the construction requirement of severe cold area completely, such as tooth timberline, tender timberline, southern weak line etc., permafrost, Nan Han tunnel are due to weather severe cold, tunnel defects such as generally ftractureing in tunnel, shortcake is broken, peel off, hang ice, Mao Shui, ponding, freeze, serious threat owner of a trading company or a workshop safety and service life, maintenance work is heavy, administers very difficult.This is mainly low due to temperature, concrete Microstructure Fracture, caused by infiltration, Chen Rong vicious circle etc.
Summary of the invention
The object of this invention is to provide a kind of fine sand type rich ice soil property injecting paste material, be particularly suitable for sand content low use frozen soil layer fracture grouting, prevent soil layer from subsiding and reinforce pretreatment.
Technical scheme of the present invention is achieved in that a kind of fine sand type rich ice soil property injecting paste material, with C
