APPLICATION OF CORE DRILLING AND ANCHOR CABLE DRILLING TECHNOLOGY IN DEEP FOUNDATION PIT SUPPORT ENGINEERING
In order to improve the integrity of obtaining geological information during the survey process of deep foundation pit support engineering,a survey method for deep foundation pit support engineering in construction engineering is proposed based on the drilling technology of core anchor cables with follow-up pipes,taking a construction site of a deep foundation pit support engineering as an example.By using the additional stress method,the exploration depth of deep foundation pit support engineering is determined,and the engineering exploration points are arranged according to the survey range.The anchor cable is tensioned and locked using the core anchor cable drilling technology with the pipe,achieving the exploration of deep foundation pit support engineering in construction engineering.The final survey results obtained are the same as those obtained from manual surveys,which also proves that the core drilling and anchor cable drilling technology with pipes has high integrity in obtaining geological information,and therefore has good application effects.
