TYHEN small and medium-sized rotary drilling rigs contributed to Xiaoxian city construction

(Summary description)Recently, TYHEN Foundation Construction mobilized four KR125A and one KR220C rotary drilling rig in Nantong sixth Construction company’s rundown areas reconstruction project. The geological conditions of the site are mainly backfill soil, clay, strongly weathered and moderately weathered limestone, and karst caves of different sizes. The depth of the pile is 13~36m, and the diameter is 600mm. The bearing layer of the pile body is moderately weathered limestone, and there should be no karst cave 10 meters below the pile, otherwise, it is necessary to pass through the karst cave to reach the ideal bearing layer. The stratum is complicated and the construction is extremely difficult, especially having to go through the karst cave, back-filled layer to re-entering into the rock. Rotary drilling rig bored into the rock again need to ensure the verticality of the pile, so the rig stability and reliability requirements are very high, with the operator's skilled judgment. At the same time, with the full support of Tyhen experts, the bore holes were smoothly drilled wining good praise from the owner and the main contractor.
