Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] refer to figure 1 , is a pile foundation static load detection device disclosed in the present invention, comprising a load-bearing plate 1, which is horizontally arranged, a counterweight 2 is arranged on the upper surface of the load-bearing plate 1, and a supporting beam is formed on the lower surface of the load-bearing plate 1 3. The support beam 3 is cross-shaped, and the support beam 3 is set horizontally so that the load-bearing plate 1 is placed flat on the support beam 3. A jack 4 is arranged below the support beam 3. The jack 4 is vertically set, and the lower end of the jack 4 is used for Abutting against the pile foundation 8 , the counterweight 2 is lifted by the jack 4 , so that the pile foundation 8 is subjected to the load of the counterweight 2 .

[0040] refer to figure 2 and image 3, the upper end of the pile foundation 8 is pr...

Abstract

The invention relates to a pile foundation static load detection device comprising a bearing plate; a counter weight is arranged on the upper surface of the bearing plate, and a jack is arranged belowthe bearing plate vertically; the lower end of the jack is used for abutting on a pile foundation, and the upper end of the pile foundation is provided with a connecting frame fixed to the pile foundation; a plurality of support rods are arranged on the connecting frame, and one end of each support rod is hinged to the bearing plate; the end, far away from the bearing plate, of each support plateis hinged to the connecting frame, and the middle part of each support rod is provided with a pull wire; and the pull wire is connected between the middle part of the corresponding support rod and the jack in a pulling mode. The detection device has the effect that normal continuous inspection of the pile foundation stress is still maintained after the support plates are inclined.

Description

technical field [0001] The invention relates to the technical field of a pile foundation static load test, in particular to a pile foundation static load detection device. Background technique [0002] Pile foundation static load test is a technology used in engineering to test the bearing capacity of pile foundations. In terms of determining the ultimate bearing capacity of a single pile, it is the most accurate and reliable inspection method at present. As a judgment of whether a certain dynamic load inspection method is mature, it is based on the comparative error of the static load test results. Therefore, each code for foundation design and treatment puts the single pile static load test in the first place. In the static load test, the load acting on the pile is generally provided by the reaction device. The ease of use of the reaction device directly affects the process and results of the test. Commonly used are surcharge reaction device and anchor pile reaction devi...
