Problems solved by technology

Because the installation methods are mainly pier type and wall type, it cannot be used for the measurement of deep displacement. At present, it is difficult to measure the displacement of different depths of the pile body, the pile bottom and the bottom of the cap. It is urgent to invent a device that can Multi-point settlement measurement system for deep pile foundation

Abstract

The invention discloses a parallel deep multi-point static leveling system used for a pile foundation and a method. The system includes a plurality of displacement measuring devices and a data collection system. Each displacement measuring device includes liquid storage tanks, a buoy, a detection rod and a sensor. The liquid storage tank is used for containing liquid, an upper part thereof is provided with a vent hole, and a lower part is provided with a liquid outlet. The buoy floats on a surface of the liquid. The top of the buoy is provided with a measuring rod. A sensor is mounted on the measuring rod. The vent holes of the multiple liquid storage tanks are in communication through a vent tube. The liquid outlets of the multiple liquid storage tanks are in communication through a liquid passing tube. The sensor of each displacement measuring device is connected with the data collection system. The data collection system can accurately collect settlement data, carry out real-time recording, and automatically draw correlation curves.

Description

technical field [0001] The invention relates to a parallel deep multi-point static leveling system and method for pile foundations. Background technique [0002] The function of the pile foundation is to transfer the upper load to the lower hard rock layer. Because of its high bearing capacity and small settlement, the pile foundation is more and more widely used in urban high-rise buildings, port terminals and seismic engineering. . The static load test of prototype piles at the engineering site is the most direct and reliable method to design and determine the bearing capacity of the pile foundation and to study the bearing deformation performance of the pile foundation. [0003] At present, the static leveling system is a precise instrument for measuring the relative elevation change between two points or multiple points. The measuring unit collects data and connects with the computer through wired or wireless communication to realize automatic observation. Because the...
