双子塔KLCC为马来西亚的一个国际性重要地标, 位于首都吉隆坡市中心。目前正在建设的双子塔二期项目的桩基工程已进入施工高峰期,该工程钻孔桩直径为2.2m和2.0m, 最大深度达105m, 地质情况极为复杂, 除了要穿过标贯值极高的覆盖层,桩基还需嵌入坚硬的石灰岩16~25m,更为复杂的是地层中还经常会遇到溶洞。宝峨两代“钻机王”BG 48和BG 46, 以及2台BG 40同时在该现场进行钻孔桩施工,为了保证如期完成该工程,由宝峨天津工厂生产的BG 38目前刚完成现场组装并已顺利投入施工。其中新一代“钻机王”BG 46配置外径559mm的、钻深可达105m的五层机锁凯氏钻杆, 负责大部分超深孔及困难地层钻孔施工。目前工程进展顺利,工程将如期顺利完成。
