Construction method for deep foundation pit excavation
The invention provides a construction method for deep foundation pit excavation. The method comprises the following steps of a mounting step, specifically, mounting a plurality of support piles at a preset mounting position; a first excavation step, specifically, performing layered symmetrical excavation in a first preset depth range away from the ground, and performing supporting after excavationis completed; a second excavation step, specifically, performing regional and symmetrical excavation in a second preset depth range away from the ground, and performing supporting after excavation iscompleted; and a third excavation step, specifically, performing regional and symmetrical excavation in a third preset depth range away from the ground, and performing supporting after excavation iscompleted. According to the construction method, excavation supporting is conducted in three layers from the ground to the underground, all the layers do not influence one another, do not collide withone another and are not limited by space, construction of foundation pit excavation operation is facilitated, displacement of a foundation pit structure is reduced, the stability, safety and stress uniformity of foundation pit supporting are improved, and the construction method is also suitable for foundation pits with small foundation pit areas and deep excavation depths, and is wide in application range.
本发明提供了一种深基坑开挖的施工方法，该方法包括如下步骤：安装步骤，在预设安装位置安装多根支护桩；第一开挖步骤，在距离地面第一预设深度范围内进行分层对称开挖，并在开挖完成后进行支护；第二开挖步骤，在距离地面第二预设深度范围内进行分区域且对称开挖，并在开挖完成后进行支护；第三开挖步骤，在距离地面第三预设深度范围内进行分区域且对称开挖，并在开挖完成后进行支护。本发明中，从地面向地下分为三个层次进行开挖支护，各层之间互不影响互不碰撞，也不受空间限制，便于基坑开挖作业的施工，并减小了基坑结构的位移，提高了基坑支护的稳定性、安全性和受力的均匀性，还能适用于基坑面积较小且开挖深度较深的基坑，使用范围大。
