Pile anchor deep foundation pit external corner supporting structure and construction method
The invention relates to a piled anchor deep foundation pit external corner supporting structure and a construction method, and belongs to the technical field of deep foundation pit engineering, the piled anchor deep foundation pit external corner supporting structure comprises a plurality of supporting piles, the supporting piles are divided into two groups to be arranged on two right-angle sides of a foundation pit external corner area respectively, and every two adjacent supporting piles are connected through a fixing mechanism; the foundation pit external corner area is internally provided with a stabilizing mechanism used for preventing the supporting piles from inclining, newly-added piles are driven into the soil body in the foundation pit external corner area according to a certain rule, and meanwhile different anchor cables are adopted for fixing the positions under the conditions that the foundation pit depth is common, the foundation pit depth is large and the foundation pit depth is very large; the problems that supporting in the external corner area of the foundation pit is weak and transverse anchor cables and longitudinal anchor cables of the external corner are mutually crossed and influenced are solved, through the technical scheme of making corresponding to different foundation pit depths, it can be guaranteed that under any condition, supporting piles in the external corner area of the deep foundation pit cannot incline towards the interior of the foundation pit, and the anchor cables cannot be crossed; the method can be widely applied to deep foundation pit engineering.
本发明涉及一种桩锚深基坑阳角支护结构及施工方法，属于深基坑工程技术领域，包括若干支护桩，若干支护桩分为两组分别设置在基坑阳角区域的两直角边上，每相邻两个所述支护桩之间通过固定机构连接，基坑阳角区域内设有用于避免支护桩倾斜的稳固机构，本发明通过在基坑阳角区域土体内按一定规律打入新加桩，同时通过对基坑深度一般、基坑深度较深和基坑深度很深三种情况采用不同锚索固定位置，解决了基坑阳角区域支护薄弱以及阳角横向和纵向锚索相互交叉影响的难题，通过对不同的基坑深度作出对应的技术方案，可以保证不论再哪一种情况下，深基坑的阳角区域中支护桩都不会向基坑内的倾斜且锚索都不会交叉，在深基坑工程中可以广泛应用。
