Brief:
Fracturing grouting reinforcement is mainly used for soil preparation or local reinforcement of soft soil foundation, the dam seepage control and ground Sedimentation appeared in the process of deep foundation pit in construction reinforcement, the plugging of seepage water of foundation pit. According to different site of grouting requirements can be divided into single hydraulic slurry and double hydraulic slurry method. General formula of the single hydraulic slurry has cement, fly ash, bentonite material composition and so on, and double hydraulic slurry is in the single hydraulic slurry formulated can make rapid solidification of cement material such as sodium silicate, rescue and commonly used in engineering.

Commonly used in grouting method, there are flowers pipe grouting and two one-way valve tube grouting method. Two methods of grouting can be used for osmotic grouting, and splitting grouting can only use one-way valve tube grouting. In the soil permeability coefficient is less than 10 cm/s - 4, generally using flower tube grouting is hard work, rather than using one-way valve tube fracturing grouting. Practice has proved that in certain depth below the ground's soil reinforcement and track grouting reinforcement, fracturing grouting construction is convenient, the advantages with better effect, especially in deep soil of fixed-point, quantitative grouting, can repeat a hole grouting is generally flower tube pressure grouting is unable to substitute.
