Fabricated foundation pit supporting structure test model device
The invention relates to an assembly type foundation pit supporting structure test model device. The method is suitable for physical model tests of foundation pit excavation support and support structure failure. According to the technical scheme, the device is provided with a plurality of straight piles which are vertically fixed to the edge of the bottom of a foundation pit and arranged in rows, waist beams and top beams are detachably installed on the waists and the tops of the straight piles through fixing buckles, a plurality of inclined piles are installed on the waists through force transmission buckles, the bottom ends of the inclined piles are supported at the bottom of the foundation pit, and the top ends of the inclined piles are supported on the force transmission buckles on the waist beams; the force transmission buckle is provided with an inverted-U-shaped buckle and a limiting angle plate, the inverted-U-shaped buckle is buckled on the waist beam, and a gap is reserved between the side face, facing the foundation pit, of the waist beam and the corresponding inner side wall of the inverted-U-shaped buckle. The cross section of the limiting angle plate is in a V shape, one side plate of the limiting angle plate is inserted into the gap between the inverted-U-shaped buckle and the waist beam and fixed to the waist beam through a screw II penetrating through the side wall of the inverted-U-shaped buckle and the side plate, and the other side plate of the limiting angle plate supports the top end of the corresponding inclined pile.
本发明涉及一种装配式基坑支护结构试验模型装置。适用于基坑开挖支护及支护结构失效的物理模型试验。本发明的技术方案为：该装置具有若干竖直固定于基坑底部边缘并布置成排的直桩，直桩的腰部和顶部经固定扣可拆卸的安装有腰梁和冠梁，腰部上经传力扣装有若干斜桩，斜桩底端支撑于基坑底部，斜桩顶端支撑于腰梁上的传力扣上；所述传力扣具有倒U型扣和限位角板，其中倒U型扣扣于所述腰梁上，并在腰梁的朝基坑侧侧面与倒U型扣的相应内侧壁之间留有间隙；所述限位角板的横截面为V字形，该限位角板的一侧板插装于所述倒U型扣和腰梁之间间隙内并经穿过倒U型扣侧壁和该侧板的螺钉Ⅱ固定于腰梁上，限位角板的另一侧板支撑相应斜桩的顶端。
