摘要
结合工程实例，介绍了复杂地层非开挖钻进铺管实践，认为在复杂地层中导向钻进，应根据所钻地层的情况及时变换适当钻头，并且适时调节冲洗液的性能。使用小型钻机在复杂地质层中回拉铺设钢管，可辅以顶管机顶进。
Combined with engineering case study, introduced non-excavating piping in complicated strata, considered that directional drilling in complicated strata should change drilling bit on time according to strata, and adjust flush fluid as well. Use small drilling rigs piping in complicated strata by pulling, assist by tube push bench.
