Fixing device of inclination measuring pipes

Abstract

The invention discloses a fixing device of inclination measuring pipes. The fixing device comprises a fixing cylinder and a sliding cylinder which are arranged at an interval from top to bottom, wherein the fixing cylinder and the sliding cylinder are coaxially arranged; a plurality of steel wires are arranged between the lower end of the fixing cylinder and the upper end of the sliding cylinder and uniformly distributed circumferentially; the upper ends of the steel wires are connected with the lower end of the fixing cylinder, the lower ends of the steel wires are connected with the upper end of the sliding cylinder, the cylinder wall of the fixing cylinder is provided with guide holes, pull rods which are vertically arranged are sleeved with the guide holes, the lower ends of the pull rods penetrate through the lower ends of the guide holes and are connected with the upper end of the sliding cylinder, and the upper ends of the pull rods extend upwards from the upper end openings ofthe guide holes; the side wall of the fixing cylinder is provided with screw holes, the screw holes are in threaded connection with locking bolts, and displacement of a deep layer of an underground structure can be greatly reduced or the expense for detecting the inclination can be greatly reduced; not only can the inclination measuring pipes be well embedded and reinforced, the accuracy of the measurement values of the inclination measuring pipes is ensured, but also the inclination measuring pipes can be conveniently recovered. The fixing device is used for detecting the displacement or inclination of the deep layer of the underground structure.

Description

technical field [0001] The invention relates to the technical field of deep displacement monitoring, in particular to a fixing device for an inclinometer pipe. Background technique [0002] Under the site conditions of soft soil layer, the construction of underground structures such as building engineering piles or foundation pit support structures, these engineering structures are extremely vulnerable to being pushed by external forces or lateral earth pressure, or due to careless construction, they will be damaged. Cause the deviation and inclination of engineering pile or foundation pit support structure. The verticality and its change value of these structures in the process of use determine whether the bearing capacity of the pile foundation of the building project or the bearing function of the foundation pit support structure can be played normally, which is directly related to the safety of the project. In order to detect the displacement and inclination of engineer...
