A model experimental device for compressing and pulling comprehensive indoor experimental piles

Abstract

The invention discloses a comprehensive indoor experiment pile model experiment device for pressing and pulling, which includes a model pile, an experiment box body, a loading device, a monitoring device and an experiment auxiliary device; the model pile is located in the center of the experiment box body, and the loading device includes a lever and Weighting weight, one end of the lever is swingingly connected to one side of the model box, the action point of the lever is above the model pile, the other end of the lever passes through the opposite side of the box wall, and the end of the lever is equipped with a hanger to suspend the weight The monitoring device includes a measuring system, a sensor system, a signal acquisition system and a signal processing system; the force of the weight is applied to the model pile through the lever and / or the steel wire rope provided on the lever. The invention has obvious beneficial effects, can conveniently carry out experiments on various types of compression piles and uplift piles, saves manpower and material resources, and improves the efficiency of experiments.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a soil engineering test instrument and equipment, in particular to a comprehensive indoor experimental pile model experimental device for pressing and pulling. Background technique [0002] The performance test of piles has always been an important means of pile foundation engineering theory. However, when conducting outdoor field experiments, a large amount of mechanical equipment, manpower and material resources are needed. [0003] Traditional outdoor field tests cannot directly observe the changes in the soil around the pile body, and it is difficult to sample the soil around the pile body after compression. The bearing capacity of the pile body will be affected by the bearing capacity of the pile tip during the experiment, etc. A lot of inconvenience. In addition, traditional outdoor experiments are difficult to monitor and record the stress state of the soil throughout the ...

Problems solved by technology

However, when conducting outdoor field experiments, a large amount of mechanical equipment and manpower and material resources are needed.

[0003] Traditional outdoor field tests cannot directly observe the changes in the soil around the pile body, and it is difficult to sample and study the soil around the pile body after compression. The bearing capacity of the pile body will be affected by the bearing capacity of the pile tip during the experiment. many inconveniences

In addition, traditional outdoor experiments are difficult to monitor and record the soil stress conditions throughout the experiment process, and cannot accurately measure the load and settlement of the pile top
