Hole cleaning: after the drilling is completed, the hole shall be cleaned, that is, the thick mud in the hole shall be replaced with thin mud. When the proportion of returned mud is less than 1.1, the hole cleaning can be completed. After hole cleaning, immediately inject casing material into the hole. Casting casing material: casing material is made by mixing cement and clay slurry in proportion (cement: clay: water: 1:1.5~1.53:1.9). Lower the tremie to 10cm from the hole bottom, and use the grouting pump to send the casing material to the hole bottom through the tremie, so that the casing material can completely replace the mud in the hole from bottom to top, until the casing material overflows from the orifice. The casting of casing materials must be carried out continuously without intermission. The time for pouring casing materials shall be as short as possible, and the time shall not exceed 20 minutes.
