旋挖钻钻孔施工技术

The Construction Technology of Rotary Drill Rig

旋挖钻钻孔施工技术是在已定孔位上反复旋挖进,把渣掏出运走,直到应钻深度的一种施工方法,适用桥梁、房建深挖基桩基础。它的特点是设备结构紧凑、就位简便、埋设护筒省力、节能环保,按照有关施工标准和规范的工艺流程施工,不仅能缩短工期,提高工程质量和经济效益,还能为保护环境提供可靠的保障。

The construction technology of Rotary Drill Rig is the method of drilling boreholes repeatedly by Rotary Drill Rig in the hole that has been scheduled, carrying out the residue until the drilling is deep enough. The method is used in digging deep - pile foundation of bridges and housing construction, it＇s characterized by compact equipment, placing the simply, laying casing effort, energy saving and environmental protection. In accordance with the relevant construction standards and norms the construction can not only shorten the construction period and improve the quality and economic efficiency, but also provide reliable protection to protect the environment.
