| description | The invention provides a sleeve valve pipe grouting reinforcement construction method for a water-rich stratum with loose soil texture. The sleeve valve pipe grouting reinforcement construction method for the water-rich stratum with loose soil texture comprises the steps of setting out and positioning a hole site of a grouting hole, and drilling the hole at the hole site vertical to the stratum to a designed depth; lowering a sleeve valve pipe into the drilling hole to the bottom of the hole and temporarily fixing the sleeve valve pipe; filling an annular gap between the outer wall of the sleeve valve pipe and the inner wall of the drilling hole with a filling layer with the fixed height to ensure that the sleeve valve pipe is fixed in the drilling hole through the filling layer; casting a sleeve shell material in the annular gap above the filling layer; and controlling the grouting pipe to conduct grouting on the sleeve valve pipe. According to the sleeve valve pipe grouting reinforcement construction method |
