Device for measuring pile settlement

The utility model relates to a device for measuring pile settlement, and belongs to the field of rock-soil and underground engineering monitoring. Comprising stand columns, connecting rods and bubble levels. The bottom ends of the stand columns penetrate into a soil layer and are fixed, and the four stand columns are connected through connecting rods at the positions close to the top ends of the stand columns to form a whole frame in an enclosing mode. The bubble level is fixed at the midpoint of each connecting rod; the stand column and the connecting rod are spatially hinged together. By means of the device, settlement of a soil layer around a pile hole at several important time nodes in the construction process of the cast-in-situ bored pile can be monitored, and construction safety control is assisted to be completed. 本实用新型涉及一种测量桩沉降的装置，属于岩土与地下工程监测领域。包括立柱、连接杆、气泡水平仪；所述立柱底端深入土层并固定，在接近立柱顶端的位置，用连接杆将四根立柱连接起来，围合成一个框架整体；所述气泡水平仪固定在每个所述连接杆的中点处；所述立柱与连接杆空间铰接在一起。通过该装置能够对钻孔灌注桩施工过程几个重要的时间节点上桩孔周围的土层沉降进行监测，辅助完成施工安全控制。
