Description
Technical Field
The application relates to the technical field of deep displacement monitoring, in particular to a fixing device of an inclinometer pipe.
Background
Under the condition of a weak soil layer site, underground structures such as building engineering piles or foundation pit supporting structures are constructed, and the engineering structures are extremely easy to push by external force or lateral soil pressure or cause deflection and inclination of the engineering piles or foundation pit supporting structures due to construction carelessness. The verticality and the variation value of the structures in the use process determine whether the bearing capacity of the pile foundation of the building engineering or the bearing function of the foundation pit supporting structure can be normally exerted, and the engineering safety is directly related. In order to detect the displacement and inclination of engineering piles and supporting structures, positioning and inclination measurement technology (inclinometry) is required to be applied, stable inclinometer pipes are arranged, and accurate data of inclination of underground structures can be obtained by observing with an inclinometer.
The burying technical methods of the inclinometer mainly comprise two methods: 1. synchronous pre-burying of concrete pouring; 2. core pulling and hole reserving post implantation. The cast-in-situ engineering pile or supporting structure (pile and wall) needs to adopt synchronous pre-buried arrangement of inclinometer pipes, and the inclinometer pipes are fixed in position along with the casting of the structure by concrete, so that the inclinometer pipes buried by the method can only be consumable materials which are put into once. Except for the tubular engineering piles such as precast concrete pipe piles, steel pipe piles and the like, the core-pulling reserved holes are monitored by arranging the inclinometer pipes after the core-pulling reserved holes are implanted in the structure to be tested or the rock stratum under the conventional condition. When the hard (rock) stratum or the existing underground structure (cast-in-situ bored pile and underground continuous wall) adopts core drilling and hole drawing, stable inclinometer pipes can be arranged in the hollow position or core pulling hole of the pile. If sand and stone landfill or cement slurry fixation is adopted for the periphery of the inclinometer pipe, the inclinometer pipe is also a disposable consumable. Whether the inclinometer pipes are synchronously embedded or post-implanted, only the materials and labor cost for the arrangement of the monitor pipes are different from thousands of yuan to tens of thousands of yuan.
