我公司(铁二局重庆工程公司)采用 CZ-30型钻机施工冲孔灌注桩已历经数十年,广泛应用于铁路、公路、市政桥梁、工业与民用建筑等的桩基础,经历过不同地质地层。对于一般沉积紧密的、坚硬的漂石及风化的基岩等一般地层,均较容易施工;而对于某些特殊地层,如多层溶洞地区、填海造陆地区、河谷
Our company (Iron 2 Bureau Chongqing Engineering Company) has been using CZ-30 drilling rigs to construct punched cast-in-place piles for decades. It has been widely used in pile foundations of railways, highways, municipal bridges, industrial and civil buildings, and has experienced different geological conditions. Formation. For general formations such as tightly packed, hard rock and weathered bedrocks, it is easier to construct; for some special formations, such as multi-layer caverns, land reclamation areas, and river valleys
