Concrete impermeability test piece pressing device

A concrete impermeability test piece pressing device comprises a vertically-arranged dowel bar, the top of the dowel bar is fixedly connected with a stiffening beam, the bottom of the dowel bar is fixedly connected with a pedestal, the stiffening beam is in threaded connection with a spiral handle, the spiral handle penetrates through the stiffening beam, the bottom of the spiral handle is connected with a pressing disc in an abutting mode, and a pointer is arranged on the pressing disc. And the dowel bar pointed by the pointer is provided with scales. The stiffening beam, the dowel bar and the pedestal are arranged to form a supporting force transmission structure, the spiral handle is manually rotated to apply pressure to the pressure plate to press the test piece into the standard cover die, the device can enable the test piece to be stressed uniformly in the pressing process, the integrity of the test piece is ensured, and the working efficiency is improved. 一种混凝土抗渗试件压紧装置，包括竖直设置的传力杆，所述传力杆顶部与加劲梁固定相连，所述传力杆底
