The sleeve valve pipe technology and split grouting reinforcement are mainly used for leveling or local reinforcement of soft soil foundations, anti-seepage of dams, reinforcement of ground settlement in deep foundation pits during construction, and plugging of foundation pit seepage. According to the different requirements of different construction sites for grouting, it can be divided into single hydraulic grouting method and double hydraulic grouting method. The general formula for single hydraulic slurry is composed of materials such as cement, fly ash, and bentonite, while for double hydraulic slurry, materials such as water glass that can quickly solidify cement are added to the single hydraulic slurry formula, which is generally used for engineering emergency response.

Composition: Composed of PVC outer pipe, galvanized grouting inner pipe, rubber sleeve, sealing ring, upper end plug and bottom conical plug.
