[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] grouting common problem of governance: one, from the high-pressure grouting equipment and drilling too Liaoning High Pressure Rotary Jetting Water Curtain, will lead to pressure loss, high gauge reading the pressure of the injection hole on the unit so that the body is less than the test piles consolidation value. Governance measures: distance high-pressure grouting equipment and drilling control within 40m. Second, note the slurry uneven mixing the slurry with a rare thick, resulting in uneven pile strength. Control measures: the slurry mixing time control is not less than 3min, storage slurry, stirring constantly, Liaoning high pressure jet grouting sealing curtain to prevent precipitation. Third, for various reasons, the high-pressure injection process is interrupted Liaoning Rotary Jetting Water curtain, pile hole will naturally precipitate slurry to continue to enhance the cement slurry spraying segregation occurs at an elevation of Minting of such low intensity that zone . Governance measures: lap length is not less than 0.2m, interruptions recovery injection Liaoning high pressure jet grouting sealing curtain, drop multiplexing spray lap length is not less than 0.5m. [Tianjin-strong high-pressure pump Co. propose to you the star product] safety measures to take to deal with the process of the construction environment slurry proper disposal, are not free to discharge in the venue. Mud pump the slurry can be pumped to the settling tank, the slurry of water and solid particles precipitation, the precipitated solids to the designated place of release
