Abstract

The invention belongs to the field of large-diameter and high-bearing-capacity foundation pile detection, in particular to a large-tonnage foundation pile pile-loading double-layer beam "sandwich" type structure ballast platform pileup method. It includes the following steps, S100~processing of the test site; S200~ erection of piled platform pier and main girder pier; S300~ loading device; S400~ erecting main girder; S500~ erecting lower level beam; Put the interlayer S700~set up the upper level beam platform; S800~place the counterweight; the invention avoids the influence of the secondary beam on the test due to the damage and deformation caused by the local stress concentration; "Word steel composition, easy to use and low cost.

Description

technical field [0001] The invention belongs to the field of large-diameter and high-bearing-capacity foundation pile detection, in particular to a large-tonnage foundation pile pile-loading double-layer beam "sandwich" type structure ballast platform pileup method. Background technique [0002] In recent years, the foundations of many important buildings (structures) in the construction field adopt large-diameter pile foundations, so the bearing capacity of foundation piles is getting higher and higher. In order to ensure the safety of the building, the bearing capacity of foundation piles must be tested and evaluated. The load test is a test method for testing the bearing capacity of foundation piles. Generally, the ultimate load exceeding 15000kN is called a large tonnage load test. This kind of large-tonnage load test requires strict control to ensure safety from the production of pile caps, the treatment of soil around piles, and the design and assembly of the overall r...
