Application of High Pressure Jet Extended Head Anchor in Anti-floating Construction of Basement
Based on engineering examples,the construction technology of high pressure jet expansion head bolt is analyzed,the construction quality of bolt is tested by field test,and the economic comparison is made with common bolt technology.The results show that the displace-ment of the bolt is positively correlated with the loading,the dispersion of the load-displacement curve of the bolt is small,and the bolt is not damaged in the test process,and the anti-floating bolt has good construction effect.
