Safety monitoring system of full-automatic static load test bed

Abstract

The invention discloses a safety monitoring system of a full-automatic static load test bed. The safety monitoring system comprises a static load platform, a deformation measuring system and a risk monitoring system; the static load platform comprises a force transmission supporting assembly, a jack, a ballast and buttresses; the jack is arranged at the upper end of a detection pile; two ends of the force transmission supporting assembly are erected on the buttresses on two sides respectively; the upper end of the jack abuts against the bottom of the force transmission supporting assembly; theballast is located at the upper end of the force transmission supporting assembly; the gravity center of the ballast, the center of the force transmission supporting assembly and the center of the jack are all superposed with a stress axis of the detection pile; the deformation measuring system is connected with the force transmission supporting assembly and used for collecting and sending deformation data of the force transmission supporting assembly in real time; and the risk monitoring system is used for receiving the deformation data, carrying out specific mathematical analysis and judging whether the force transmission supporting assembly has a lifting risk and an overturning risk or not. According to the safety monitoring system of the full-automatic static load test bed, risks in the static load test process can be effectively monitored and found in advance, and safety accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of pile foundation detection, and in particular relates to a safety monitoring system for a fully automatic static load test bed. Background technique [0002] Single pile vertical compressive static load test is the most commonly used method for pile foundation testing. It sets concrete buttresses on both sides of the test pile, and utilizes the main beam on the test pile and the multi-row distributed beam weight across the concrete buttress. The blocks together form a static load test bench, and the test pile is loaded by the reaction force generated by the upward load of the jack on the test pile, and the displacement of the top of the pile is recorded at the same time. [0003] However, in engineering applications, due to the insufficient weight or eccentricity of the counterweight stones and the insufficient bearing capacity of the foundation soil, various major safety accidents such as lifting and over...

Problems solved by technology

[0003] However, in engineering applications, due to the insufficient weight or eccentricity of the counterweight stones and the insufficient bearing capacity of the foundation soil, various major safety accidents such as lifting and overturning of the static load test bench occurred, which caused huge damage to the lives and property safety of the test workers. threaten

At this stage, the manual observation method is generally used for the risk of static load test benches, and there is a serious lag
