Recently, Taiheng foundation KR285CS low headroom rotary drilling rig construction in Hangzhou Nongfu Spring Project. The project is constructed in the factory building, with a height limit of 11 meters, a narrow construction scope, a field aperture of 600mm, and a hole depth of about 6~18m. The geological conditions are mainly backfill soil layer, sand layer, backfill limestone and sandstone. The geological construction conditions are relatively complex. The backfill limestone has a large volume and a particle size of 200-2000mm. Drilling has great influence on the hole wall and the hole. The stone falls off the hole wall and the hole wall is very easy to collapse. Because the maximum content of large rocks in the backfilled stratum is more than 80%, long casing cannot be used for wall protection in site construction. In order to reduce the customer's cost, after drilling through the collapsed hole wall, red soil or clay is used for backfilling after backfilling limestone, and it is tightly compacted. The construction is extremely difficult. Passing through the backfilling formation requires 2 meters into the rock, which tests the stability and reliability of the drilling rig and the judgment ability of the operator. With the full support of Taiheng foundation construction experts, the hole is smoothly formed and won the unanimous praise of the owner Party A.
