Technologies of Collapsed Pile Pore Treatment with Home-made Grouting Device for Pore Excavation Piles

介绍灌注法灌浆的目的、施工材料的选用及适用性 ,同时计算浆液扩散半径及容许灌浆压力。自制注浆设备处理挖孔桩坍孔 ,最终扼制流砂现象 。

In this article,the author introduces some aspects of grouting of the grouting method such as purposes,selection and applicability of construction materials,and how to calculate the diffusion radius of slurry and the allowable grouting pressure.Engineers adopted home-made grouting device to handle collapsed pores of pore excavation piles,finally stopped shifting sand and ensured the successful and safe construction of excavation piles.
