喷冲气举机构试验研究

Experimental Research on the Jetting and Air-pumping Mechanism

介绍了气举机构的工作原理,并对正压冲固平台特定沉贯施工条件下的多种气举泵设计方案进行了系列试验研究。试验研究获取了气举装置的输气量与排水量的关系和气举高度特性以及各种泵体结构参数,为正压冲固平台基础的沉贯设备设计提供了科学依据。

In this paper, the working fundamentals of air-pumping mechanism are introduced, and the experimental researches on different air-pumping device design schemes under the penetration construction conditions of jetting and cementing platform were made. The relationship between air-input and displacement of air- pumping device, the characteristics of air-pumping height and different parameters of pump structure were obtained, which provides scientific basis for designing the penetration equipments of jetting and cementing platform foundation.
