Horizontal foundation bearing capacity testing equipment and testing method

Abstract

The invention discloses horizontal foundation bearing capacity testing equipment and a testing method, and belongs to the field of geological in-situ test. The problem of larger error of experimental data measured by conventional equipment is solved. The testing equipment comprises a working plane, a drill rod, a railway upright column, a power chain, a power head and a drilling test device; the drilling testing device comprises a testing device and a tunneling device; the tunneling device is positioned below the testing device; the testing device comprises a steel plate frame, a hydraulic jack group and a pressure sensor; the hydraulic jack group is arranged in the steel plate frame; the pressure sensor is arranged at the end part of the telescopic end of the hydraulic jack group. Radial feeding is conducted by using the minitype hydraulic jack, and the bearing capacity of the horizontal foundation is tested by accurately controlling the journey of the jack, experimental data is acquired, the traditional flat plate experiment and stacking load experiment methods are broken, manpower and material resources required by experiments are greatly reduced, and the acquired experimental data is more accurate.

Description

technical field [0001] The invention belongs to the field of geological in-situ testing, in particular to a horizontal foundation bearing capacity testing device. Background technique [0002] At present, most of the tests for testing the bearing capacity of the foundation are to test the vertical bearing capacity. In the traditional horizontal bearing capacity test method, the push pile test and the side pressure test are generally used. The shortcomings of the side pressure test are: Yes: The measured foundation bearing capacity, foundation coefficient and elastic modulus cannot be directly applied, and the data source obtained from the test needs to be converted from physical quantities, which increases the test cycle. Moreover, the compression control of this method is inaccurate, and the pressure received is "confining pressure", which leads to large errors in the experimental data obtained, and has limitations in practical engineering application reference.
