The invention discloses a large-span foundation pit soil layer temporary supporting system, and belongs to the technical field of soil layer temporary supporting. The large-span foundation pit soil layer temporary supporting system comprises a fender post which is inserted into the ground to form a continuous fender body, wherein a surrounding purlin bracket is arranged on the inner side of the fender post, a surrounding purlin is arranged at the upper end of the surrounding purlin bracket, and the surrounding purlin is connected end to form a supporting area; a middle connecting beam is in adouble-Y bottom butt joint shape, and the two ends of the middle connecting beam are connected with the two opposite side edges in the surrounding purlin correspondingly; and an oblique angle connecting beam is in a linear shape, and the two ends of the oblique angle connecting beam are connected with the two perpendicular side edges of the surrounding purlin correspondingly. The large-span foundation pit soil layer temporary supporting system can meet the requirement for supporting side face soil pressure, the structure is simple, mounting is convenient, enough space is reserved for the construction process, and in addition, the large-span foundation pit soil layer temporary supporting system can be repeatedly used after being dismounted.

本发明公开了一种大跨度的基坑土层临时支撑系统，属于土层临时支撑技术领域。包括：围护桩插入地下，形成连续的围护体。围护桩的内侧设置有围檩托架，围檩设置在围檩托架的上端，围檩首尾相接形成支撑区域。中间连接梁的形状呈双Y底部对接状，中间连接梁的两端分别与围檩内相互正对的两侧边连接。斜角连接梁呈直线型，斜角连接梁的两端分别与围檩相互垂直的两侧边连接。本发明提供的一种大跨度的基坑土层临时支撑系统，可满足对侧面土压的支撑，结构简单，便于安装，给施工过程预留有足够的空间，此外拆卸后可重复使用。
