摘要
结合具体工程实例介绍了气动(锤击式)小口径顶管技术的原理及施工工艺,分析了气动(锤击式)小口径顶管施工管材选择问题。着重介绍了对切土头、气压出土、减摩等工艺的技术改进措施。
The author introduced principle and building technology about air-powered (hammering) small-bore pipe jacking problems about pipe material choice with a practice. Then, improving measures about instrument pipe, air-power coming out of earth, reducing friction were emphasized.
