Laboratory self-control pile sinking device

Abstract

The invention belongs to the technical field of traffic transportation and building test equipment. The invention relates to a laboratory self-control pile sinking device. A hydraulic oil cylinder isconnected with a high-pressure oil pump and a loading controller serving as a controller to form the pile sinking device. When pile sinking is automatically controlled in a laboratory, a counter-forceframe is used as a supporting system for automatically controlling pile sinking; a gear and a rack are driven by a motor to perform lifting control of the laboratory self-control pile sinking device;a miniature laser displacement meter monitors the positions of the pile sinking device and a pile body and the perpendicularity condition of the pile body in a laboratory; and a leveling rod is usedfor monitoring the perpendicularity of the pile body during initial pile sinking, and the miniature laser displacement meter and the leveling rod are used for monitoring the perpendicularity of the pile body at the same time. Therefore, the perpendicularity of the pile body is guaranteed, a pipe pile can be conveniently, rapidly and accurately sunk to a designated position, and a laboratory modelpipe pile test is successfully completed.

Description

Technical field: [0001] The invention belongs to the technical field of transportation and construction test equipment, and relates to a laboratory self-controlled pile sinking device. Background technique: [0002] In recent years, my country's infrastructure has continued to develop. In transportation and construction, pile foundation is an indispensable foundation type. Due to its high bearing capacity, reliable quality, fast pile making speed, convenient construction, clean site and relatively economical , The advantages of small impact on the surrounding environment have been more and more widely used. There is an urgent need to study the load-bearing performance of open pipe piles. Therefore, a large number of laboratory model pipe pile tests are needed to provide a reliable theoretical basis for the on-site construction of prefabricated pipe piles. Most of the existing laboratory pile sinking devices are fixed positions and cannot be moved, while a few pile sinking de...

AI Technical Summary

Problems solved by technology

Most of the existing laboratory pile sinking devices are fixed positions and cannot be moved, while a few pile sinking devices that can move horizontally are small in size, which limits the size of the model pile, making the size effect obvious, large eccentricity, large errors, and poor test results. Not ideal, therefore, it is necessary to design a laboratory self-controlled pile driving device to meet the pile driving test of laboratory model pipe piles
