[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] common failings of governance to enhance the operating port but not when spraying cement slurry out, there is a large gap in the soil, the loss of the slurry Dandong rotating water - resisting curtain price, cause orifice not take slurry, the slurry flow should not gap at the reinforcement. Governance measures: shotcrete lifting operation, to observe the situation orifice take slurry, if not the entire hole oozing slurry Dandong rotating water - resisting curtain price, should immediately identify the reasons for processing. Other matters reference design drawings Dandong rotating water - resisting curtain prices, specification and project department regulations.
