顶管施工中采用钢花管注浆加固土体技术

Technology of applying perforated steel pipe grouting reinforced soil body in pipe-jacking construction

介绍了钢花管注浆加固施工的特点及工艺原理,并从测量放样、钻孔、钢花管加工运输、浆液制备、注浆等方面,阐述了顶管施工中采用钢花管注浆加固土体的技术要点,达到了加固地层、减少土体扰动的效果。

The thesis introduces construction features and technological principles of perforated steel pipe grouting reinforcement. Starting from aspects of sampling,drilling,perforated steel pipe manufacture and transportation,slurry prefabrication and grouting,it describes technological points of applying perforated steel pipe grouting reinforced soil body in pipe-jacking construction,which achieves the effect of reinforcing stratum and reducing soil disturbance.
