随着基坑工程深度的增加,相应的基坑工程施工难度也增大。尤其在城市和工程地质、水文地质条件差的地区,施工的困难就更大。一般而言支护方式有多种,如:直接放坡、喷锚支护、桩锚结构支护以及地下连续墙支护。它们各有特点,直接放坡的工期虽然最短最经济,但受施工场地的限制。所以,需要将深基坑支护施工作为一个有机整体,围绕质量管控进行施工管理,保证深基坑支护施工质量及边坡安全,促进建筑行业的整体发展。文章就此进行分析。
With the increase of the depth of foundation pit engineering, the corresponding difficulty of foundation pit construction also increases. Especially in urban and engineering geology, hydrogeological conditions in poor areas, construction more difficult. In general there are a variety of support methods, such as: direct grading, spray anchor support, pile anchor structure support and underground diaphragm wall support. They have their own characteristics. The shortest and most economical timetable for direct grading is limited by the construction site. Therefore, it is necessary to take the construction of deep foundation pit support as an organic whole and carry out construction management around quality control to ensure the construction quality of deep foundation pit support and slope safety, and promote the overall development of the construction industry. The article analyzes this.
