Research on Casing Rotator and Full Casing Construction Technology
摘要
Abstract
The paper summarized the research actuality and application fields both in China and abroad.The design struc-ture, specification and key techniques of QHZ-2000 casing rotator are elaborated.The paper analyzes the structure princi-ple and the application characteristics of casing string, hammer grab and drilling tools for underground obstacles removal;and also summarizes the construction process, mechanism and applicable scope of full casing cast-in-place pile, under-ground obstacles removal and pile extraction in full casing.This study fills the gap of independent research and development of casing rotator in China;it is environmental, universal and safe piling equipment and a new foundation drilling method with no mud used in urban construction and foundation works.关键词
