Pressing and pulling integrated experimental indoor pile model test device

Abstract

The invention discloses a pressing and pulling integrated experimental indoor pile model test device. The pressing and pulling integrated experimental indoor pile model test device comprises a model pile, an experimental box body, a loading device, a monitoring device and an auxiliary experimental device, wherein the model pile is positioned in the center of the experimental box body; the loading device comprises a lever and heavy weights, one end of the lever is connected to the box wall on one side of the experimental box body in a swinging manner, the application point of the lever is positioned above the model pile, the other end of the lever penetrates the box wall on the opposite side, and a suspender used for suspending the heavy weights is arranged at the tail end of the other end of the lever; the motoring device comprises a measuring system, a sensing system, a signal acquisition system and a signal processing system; and the acting force of the heavy weights acts on the model pile by the lever and / or a steel wire rope on the lever. The pressing and pulling integrated experimental indoor pile model test device has obvious beneficial effects, can be used for conveniently conducting experiments on various compressive piles and uplift piles, saves both manpower and material resources and improves the experimental efficiency.

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
