Indoor physical model test device for foundation pit excavation support
The invention discloses a foundation pit excavation support indoor physical model test device. The device comprises a model box, an unearthing funnel, a support system, a pit top surface settlement monitoring system and a horizontal displacement monitoring system. A soil outlet and a sliding opening and closing door are reserved at the bottom of the right end of the model box. A supporting system is installed in the model box and used for simulating retaining structure soil retaining in the foundation pit excavation process. The top of the model box is provided with a ground settlement monitoring system. The supporting structure horizontal displacement monitoring system adopts a mode that a lead penetrates into a sleeve, two ends of the lead are respectively connected with a fender post and a measuring meter, and two ends of the sleeve are fixed on a positioning rod and a side surface measuring hole of a model box. The device can be used for different foundation pit excavation supporting physical model tests, excavation and cleaning of a soil body in a foundation pit are facilitated, meanwhile, settlement deformation of the top of the foundation pit and horizontal displacement of a supporting pile at different depths can be accurately obtained, and a basis is provided for research on foundation pit excavation supporting stress and deformation rules.
本发明公开了一种基坑开挖支护室内物理模型试验装置，该装置包括模型箱、出土漏斗、支护系统、坑顶地表沉降监测系统、水平向位移监测系统。模型箱左端外侧安装出土漏斗，右端底部预留出土口和滑动式开关门。模型箱内安装支护系统，用于模拟基坑开挖过程中围护结构挡土。模型箱顶部安装地表沉降监测系统。支护结构水平向位移监测系统采用引线穿入套管形式，将引线两端分别连接围护桩和测量表，套管两端固定在定位杆和模型箱侧面测量孔上。本发明可以用于不同基坑开挖支护物理模型试验，方便基坑内土体开挖和清理，同时可准确获得基坑顶部沉降变形和支护桩不同深度水平向位移，为研究基坑开挖支护受力和变形规律提供依据。
