Foundation pit settlement detection device
The invention relates to the technical field of settlement detection, in particular to a foundation pit settlement detection device which comprises a cylinder, a pressure sensor and a first pressure regulating mechanism. The first pressure regulating mechanism comprises a mounting column, a sealing column and a pressure balancing assembly, the mounting column is fixedly mounted at the top of the barrel, a through groove communicating the cavity with the outside of the barrel is formed in the mounting column, the sealing column is slidably arranged in the through groove, and the pressure balancing assembly can control the sealing column to slide in the through groove; the pressure difference between the gas in the cavity and the gas outside the barrel is kept at a second preset value; when the pressure difference between the gas in the cavity and the gas outside the cylinder body is a first preset value, the cavity is communicated with the outside of the cylinder body, and when the pressure difference between the gas in the cavity and the gas outside the cylinder body is a second preset value, the cavity is separated from the outside of the cylinder body, and the pressure in the cavity is still within the range which the pressure sensor can bear. And the measuring range of the pressure sensor is indirectly improved.
本发明涉及沉降检测技术领域，特别是涉及一种基坑沉降检测装置，包括筒体、压力传感器和第一调压机构；第一调压机构包括安装柱、封闭柱和衡压组件，安装柱固定安装于筒体的顶部，安装柱上开设有连通空腔和筒体外部的通槽，封闭柱滑动设置于通槽中，衡压组件能够控制封闭柱在通槽中的滑动，使空腔内气体与筒体外部气体之间的压强差保持为第二预设值；当空腔内气体与筒体外部气体之间的压强差为第一预设值时，空腔与筒体外部连通，当空腔内气体与筒体外部气体之间的压强差为第二预设值时，空腔与筒体外部隔断，空腔内的压力仍在压力传感器所能承受的量程内，间接提高了压力传感器的量程。
