Static test device for engineering pile detection

Abstract

The invention discloses a static test device for engineering pile detection. The static test device for engineering pile detection comprises a tray and an ejector rod. The top of the ejector rod is provided with a spherical support. The tray is connected to the spherical support. The static test device for engineering pile detection further comprises a supporting component which is located below the tray and used for buffering the tray. The supporting component comprises a supporting assembly and a buffering assembly. Due to the fact that the supporting component is arranged at the position ofthe tray, when balance weight pieces are stacked on the tray, the tray is impacted and shakes up and down or moves downwards, elastic potential energy of damping springs is improved after the dampingsprings are compressed, buffering is carried out on the tray, moreover, when the tray descends to the position where supporting blocks make contact with the top of a main plate, the main plate generates supporting force to support and buffer the tray, the loss and damage of the tray and the balance weight pieces are reduced, and the service life of the tray and the balance weight pieces is prolonged. When the balance weight pieces with a buffering function are used in cooperation with the tray provided with the supporting component, the buffering performance and effects are more prominent, the loss of equipment is reduced, and the service life of the test equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of hydropower engineering construction, in particular to a device with a buffer function for static load testing of engineering piles. Background technique [0002] The qualification of testing engineering piles is mainly bearing capacity and integrity. Bearing capacity is the ability to resist load, and integrity is whether the foundation pile itself has any defects. The bearing capacity usually refers to the vertical bearing capacity for most foundation piles, that is, the settlement of the foundation pile must be within a certain range when the foundation pile is subjected to the upper load, and the most unfavorable thing for various building structures is the settlement beyond the range, especially uneven settlement. The most important method for detecting the vertical compressive bearing capacity of various foundation piles is to carry out the vertical compressive static load test of single pile found...

AI Technical Summary

Problems solved by technology

[0005] In practical applications, when performing static load tests on engineering piles, the configuration parts are usually stones or iron products with a certain weight. The test is carried out by stacking counterweights on the force device, because the pallet or the load reaction device does not have a buffer structure, and the counterweight itself does not have a buffer function. The force device causes a very large impact force, which also causes the counterweight to collide with the pallet, which is easy to cause damage, affects the service life of the experimental equipment, and cannot meet the needs of use
