地牛在大型管线穿套管施工中的应用初探

摘要

对地牛的用途、特点、构造进行了介绍，结合工程实例，分析了地牛在大型管线穿套管施工中的应用技术，并探讨了地牛在施工中产生的经济效益，指出运用地牛滚动原理，由牵引装置拖拽管道，提高了推送功效，极大地降低了施工成本。%The paper introduces the usages, features and components of the forklift, analyzes the application technique of the forklift in the large-scale pipeline casing construction by combining with examples, explores its economic benefits in the construction, and points out its rolling mech-anism by drawing the device to drag the pipeline, so as to improve the propelling effect and lower the construction cost.
