Model barrel device for indoor vacuum preloading model test
The invention relates to a model barrel device for an indoor vacuum preloading model test. The model barrel device comprises a barrel cover, a bottom plate and a model barrel body, wherein the model barrel body is made of transparent materials, a first flange and a second flange are respectively arranged at an upper end opening and a lower end opening of the model barrel body, the first flange is connected with the barrel cover, and the second flange is connected with the bottom plate in a sealed mode; the bottom plate and the model barrel body form a cavity for containing a soil body; a vacuum film is arranged on the upper end of the model barrel body, and the outer edge of the vacuum film is tightly pressed between the first flange and the barrel cover; a vacuum meter hole, a pore water pressure sensor hole and a vacuum pump connecting pipe hole are formed in the upper wall surface of the model barrel body in a penetrating mode, a first rubber plug and a second rubber plug are respectively arranged in the vacuum meter hole and the pore water pressure sensor hole, and a vacuum measuring head and a pore water pressure sensor are respectively inserted into the first rubber plug and the second rubber plug from the outside; and a drainage plate, the vacuum measuring head and the pore water pressure sensor are arranged in the soil body, and the drainage plate is connected with a vacuumizing system through a wired hose. According to the model barrel device, a side surface opening and vacuumizing mode is adopted, so that the precision of test data is increased.
一种用于室内真空预压模型试验的模型桶装置,包括桶盖、底板和透明材质制成的模型桶体,模型桶体的上、下端口分别设有第一翻边、第二翻边,第一翻边与桶盖连接,第二翻边与底板密封连接;底板与模型桶体形成用于容纳土体的空腔;模型桶体的上端设有真空膜,真空膜的外边缘压紧在第一翻边与桶盖之间;模型桶体的上部壁面贯穿设有真空表孔、孔隙水压力传感器孔和真空泵连接管孔,真空表孔、孔隙水压力传感器孔内分别设有第一橡胶塞、第二橡胶塞,分别从外部插入真空测头、孔隙水压力传感器;土体内设有排水板、真空测头、孔隙水压力传感器,排水板通过钢丝软管与抽真空系统连接。本发明采用侧面开孔抽真空的形式,提高了试验数据精度。
