| description | The invention relates to a large-section deep hole grouting construction method for a complex stratum in a water-rich area, which belongs to the technical field of underground engineering construction, and is characterized in that different grouting slurries are selected by combining different surrounding rock conditions, and the slurry with the optimal mix proportion is obtained by matching with a test in a laboratory. During site construction, the grout proportion is dynamically adjusted, the grout gelation time is adjusted, and the grouting and water stopping effect is guaranteed. The deep hole grouting hole sites are arranged according to the section of the pilot tunnel, in order to achieve the section water stopping effect and the waterless excavation condition, multiple sets of deep hole grouting hole sites are arranged along the side wall of the pilot tunnel at intervals, each set of deep hole grouting hole sites are continuously arranged in the vertical direction, and the number of each set of deep ho |
