Pile fixing device and method for pile foundation model test

Abstract

The invention discloses a pile body fixing device and method for a pile foundation model test, and solves the problem that a pile foundation model test in the prior art cannot realize differential settlement of a pile foundation. The pile body fixing device and method for the pile foundation model test have the effects of simple structure, convenient operation and capability of meeting multiple sets of diversification requirements of the model test. The technical scheme is as follows: the device comprises a model box, a pile body fixing device body and a movable clamping device, the model boxis used for filling soil samples, the pile body fixing device body comprises an upper supporting plate and a lower supporting plate, the upper supporting plate and the lower supporting plate are connected through a plurality of screws, the corresponding positions of the upper supporting plate and the lower supporting plate are uniformly provided with a plurality of through holes, and the movable clamping device is arranged above the model box and can clamp the pile fixing device body after the pile fixing device body is placed in the model box.

Description

technical field [0001] The invention relates to the field of pile foundation model tests, in particular to a pile fixing device and method for pile foundation model tests. Background technique [0002] Model test refers to the method of conducting corresponding tests on a specific engineering geological problem according to a certain similarity principle in a laboratory environment with a reduced or proportional model to obtain relevant data and check design defects. The main research method in the field of engineering. Pile foundation, as the foundation form widely used in my country at present, is widely used in high-rise buildings, bridges, high-speed rail and other projects. Therefore, to determine the pile bearing type and accurately calculate the ultimate bearing capacity of the pile body, to ensure that the pile foundation can meet the needs of the project, the superstructure (structure) To ensure that the building can operate safely, it needs to be tested and verifie...

Problems solved by technology

The inventors found that in the pre-embedding method, the method of fixed connection of the top of the pile is mostly used for fixing the piles, and there is no difference in the settlement between the piles, which is quite different from the actual project. At the same time, the settlement and soil pressure of the single pile in the pile group cannot Carry out effective measurement, bring large error to model test
