Abstract

The invention discloses a vertical loading device for simulating the pile sinking process of a static pressure pile. A body structure comprises a model casing, a soil body, a model bar, self-balanced type loading reaction frame stand columns, stand column linear guide rails, a self-balanced type loading reaction frame lower cross beam, a self-balanced type loading reaction frame upper cross beam, a sucker base, a microcomputer control electro-hydraulic servo jack, a loading data controller, a guiding device horizontal sliding rod, guiding device sliding sleeves, an opening type casing pipe, a fixed base, a force transmission rod and a cushion block. Compared with the prior art, the guiding device horizontal sliding rod can slide freely on the self-balanced type loading reaction frame stand columns through the guiding device sliding sleeves, vertical loading in the pile sinking process of the static pressure pile is simulated, test data are accurate, and the testing efficiency is high.

Description

technical field [0001] The invention belongs to the field of pile foundation engineering, and relates to a loading device for simulating the process of sinking static pressure piles, in particular to a vertical loading device for simulating the process of sinking static pressure piles. Background technique [0002] Pile foundations have a wide range of applications, and a large number of industrial buildings and civil buildings use pile foundations. With the development of industrial technology and engineering construction, research on pile design theory and design methods, construction technology and pile bearing capacity has proposed more high demands. At present, static pressure piles are environmentally friendly due to the fact that they have no noise, no vibration, and good environmental protection. With the improvement of static pressure pile construction technology and machinery, static pressure piles are more and more suitable for urban areas with high requirements f...
