Embodiment

[0048] figure 1 shows a structural view of an implementation of the static load test device 010 in the embodiment of the present invention (additionally shows the foundation pile 1 to be tested with a dotted line in the figure); figure 2 for figure 1 top view.

[0049] see figure 1 , figure 2 , the embodiment of the present invention also provides a static load test device 010, which includes a jack 3 and a large tonnage static load test reaction force structure 100. The force jack 3 is configured to be vertically supported on the upper surface of the foundation pile 1 to be tested, and the large-tonnage static load test reaction force structure 100 is supported on the force jack 3 for providing reaction force. Its use method is that the large-tonnage static load test reaction force structure 100 is fixedly connected to the foundation, and the jacking force 3 applies jacking force to the large-tonnage static load test reaction force structure 100, and the counterforce of...

Abstract

The invention relates to the field of buildings, aims to solve the problem that measured results are great in deviation as a test device in the prior art performs test on a large-tonnage foundation pile, and provides a large-tonnage static-load test counter-force structure and a static-load test device. The large-tonnage static-load test counter-force structure comprises a main beam, a stand column and inclined pulling structures, wherein the stand column is perpendicularly arranged on the mid-span position of the upper surface of the main beam in the vertical direction; the portions, at the two sides of the stand column, of the main beam are tensioned at the upper end of the stand column through the inclined pulling structures separately; and the inclined pulling structures at the two sides are symmetrical with respect to the stand column. Anti-pulling structures which are anchored on a foundation are separately arranged on positions near the two ends in the length direction of the main beam; the lower ends of the anti-pulling structures are anchored; and the upper ends of the anti-pulling structures are configured to match with corresponding ends of the main beam, and can limit upward displacement, in the vertical direction, of the main beam. The large-tonnage static-load test counter-force structure has the beneficial effects that the structure can be integrally suitable forthe foundation pile static-load test with larger tonnage, and can obtain higher measuring precision.

Description

technical field [0001] The invention relates to the construction field, in particular to a large tonnage static load test reaction force structure and a static load test device. Background technique [0002] Static load test is a test used to test the bearing capacity of foundation piles. It is usually based on the reaction force structure that provides the reaction force, and the foundation pile is pressed down with a force jack, and then the settlement value of the foundation pile under the test load is measured, which is used for calculation and analysis to obtain the bearing capacity of the foundation pile. [0003] However, the test device in the prior art has the problem of large deviations in measurement results when it is used to perform the test on foundation piles of large tonnage. Contents of the invention [0004] The present invention aims to provide a large-tonnage static load test reaction force structure to solve the problem that the test device in the pri...
