Transparent soil model pile experimental testing device and application method thereof

Abstract

The invention relates to a transparent soil model pile experimental testing device and an application method thereof. The whole system comprises an experiment table and a model experiment device, wherein the experiment table can be leveled through setting adjustable table legs; a desktop is provided with a bracket and a bracket fixing plate so as to mount an engineering diffuser, a camera and a laser device, and is provided with a slide model fixing plate and a vertical and transverse slide limiting plate so as to position and fix a model testing groove; a counter-force frame is arranged above the model testing groove, is adjusted by an adjustable type screw rod and a fixed screw cap and is fixedly arranged on the tabletop; the counter-force frame is provided with a small-size hydraulic jack and a pressure meter; artificially synthesized transparent soil is arranged in the model testing groove and the model testing groove is provided with a model pile and a model pile loading head so as to carry out a post-period model test. The whole system is reasonably arranged, and a loading test and observation on displacement and deformation conditions can be conveniently carried out on the model pile in the artificially synthesized transparent soil.

Description

technical field [0001] The invention relates to a transparent soil model pile test system and a use method thereof, which are mainly suitable for research in fields such as the loading and sinking process of miniature model piles in a laboratory, soil failure modes, and the like. Background technique [0002] Pile foundations are widely used in many engineering fields such as high-rise buildings, railways, highways, bridges, ocean platforms and port terminals. With the advancement and development of technology, various types of piles have emerged as the times require, and have been used in various projects and have occupied an important position. In order to better study the bearing capacity characteristics of various pile foundations and carry out more technological innovations, indoor experiments on various model piles are gradually increasing. In the field experiment, the stress deformation of the pile foundation and the settlement deformation of the soil can only be mon...

Problems solved by technology

Before the patent of this invention, there was already a preparation method of artificially synthesized transparent soil material (201410178910.9) and a model test device for measuring the internal displacement of soil during the soil extraction process and its use method (201410178638.4). Both inventions are under examination , but no detailed development and research on the experimental device system was carried out for the loading and sinking of the model pile in the artificial synthetic transparent soil, the force deformation and the settlement deformation of the soil around the pile.
