摘要
在昆明市盘龙区世博停车场内地下连续墙施工中,采用了中风化岩层地下连续墙入岩成槽施工工艺,该施工工艺进行了改进,在不增加机械设备的情况下极大地改善了入岩段连续墙偏孔的问题,且缩短了成槽时间,效果显著。通过对相同地质条件下两种施工工艺进行了数据上的比对分析证明,改进后施工工艺具有推广应用价值。
Based on the construction technology of the underground continuous wall of intermediate weathering rock found in the Kunming Metro Line 5 station, the construction process was studied and practiced in the construction of the underground continuous wall in the parking lot of the Expo in Panlong District, Ktmming. Improvements have been made to greatly improve the problem of the offset hole in the continuous wall of the rock entering the section without increasing the mechanical equipment, and the slotting time is shortened. The effect is significant. The data analysis and analysis of the two construction technologies under the same geological conditions are mainly conducted to prove that the improved construction technology does have promotion and application value.
