Abstract

The invention relates to a pile sinking guide rail used for indoor tests, and belongs to the technical field of construction. The pile sinking guide rail includes a guide rail, which is closed on three sides and open on one side. A connecting plate is fixed on the upper part of the guide rail, and an adjuster is connected to each inner side of the guide rail. The guide rail is connected to the model box through the connecting plate, and the regulator and Model stake contacts. In the present invention, the steel plate on the guide rail is connected to the model box for limit fixing, and the pile body is kept vertical during the pile sinking process through the regulator, which is simple and convenient, effectively improves the test efficiency, and solves the gap between the model pile and the model box wall in the pile sinking process. Problems with penetration into sandy soil.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a pile sinking guide rail for indoor tests. Background technique [0002] Among all kinds of civil engineering, geotechnical engineering occupies a very important position. As geotechnical engineering involves rock, soil, underground, and water in civil engineering, it is usually necessary to use static pressure piles. The pile pressure mechanism of the static pile driver is provided by the weight of the pile driver and the counterweight on the frame The prefabricated piles are pressed into the design elevation by counter force, which avoids the vibration, noise and pollution caused by hammering piles compared with hammering piles. [0003] At present, scholars at home and abroad have carried out a lot of research on the soil deformation around the pile caused by the pile sinking process. Many scholars use the indoor test method to press the model pile into the soil through...
