The invention discloses a device and a method for monitoring differential settlement in portfolio for a soil-stone combined region with a hydraulic structure. The device comprises a bottom-through shaft and an inner carrying tube positioned inside the bottom-through shaft, wherein a displacement station is arranged in the inner carrying tube; drill driving devices are symmetrically arranged on two sides of the displacement station, and are connected with conical drills; the drill driving devices on two sides are respectively connected with lifting devices which are used for promoting motion of the drill driving devices; correcting devices which are used for correcting level of the displacement station are symmetrically arranged at two ends of the displacement station; the middle part of the displacement station is connected with one end of a group of symmetrically arranged springs, and the other end of each spring is hinged with a vertical measuring tape; an optical fiber hanging drum is arranged between two springs, and is filled with a corrugated loop optical fiber; and an optical fiber buckle is arranged on the corrugated loop optical fiber. The device has the advantages of use repeatability, convenience in assembly, real-time detection and maintenance and the like, and has the characteristics of distribution type, micro-macro structure, real-time performance, high adaptability to complex environment and the like.
Description
technical field [0001] The invention relates to a monitoring method of a combination monitoring device for uneven settlement in an earth-rock combination area of ââa hydraulic structure, which belongs to the field of construction. Background technique [0002] The soil-rock bonded areas in hydraulic structures such as embankments and sluices often have uneven settlement during operation, which has adverse effects on the safety and normal use of buildings, and even leads to building damage or accidents. By arranging monitoring instruments or devices in the soil-rock combination area, real-time acquisition of regional settlement information, reasonable analysis of the spatial and temporal variation of regional settlement, timely detection of abnormal conditions of regional settlement (especially uneven settlement), and scientifically taking preventive or control measures, It is of great significance to ensure the safe service of hydraulic structures. [0003] At present, conv...
