Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: while the jacking mechanism on the beam exerts a lifting force on the lifting base frame, it also applies a downward pressure to the beam, which is transmitted to the ground by the two support seats below the beam. ;The positions of the two support bases may be subsidence in different degrees due to the difference in the underground soil layer, which will make the beam skew and cause the jacking force exerted by the jacking mechanism on the lifting base frame to deviate from the vertical direction, eventually resulting in The detection value of anti-floating engineering pile load test is too large or the test data is distorted

Embodiment 1

[0040] refer to figure 1 , is an anti-floating engineering pile vertical load test detection device disclosed in the present invention, comprising a first support base 1, a second support base 2, a beam 3, a lifting base frame 4, a connecting frame 5 and a jacking mechanism, wherein, The first support base 1 and the second support base 2 are installed symmetrically on the ground on both sides of the anti-floating engineering pile 14 respectively. The lower end surface of the second support base 2 is larger than the lower end surface, increasing the contact area between the first support base 1 and the second support base 2 against the ground. The crossbeam 3 is a strip-shaped steel beam, and the crossbeam 3 is erected between the first support base 1 and the second support base 2 .

[0041] refer to figure 1 and figure 2 , the upper end of the first support base 1 is provided with a hinge groove 1a, one end of the beam 3 is hinged to the first support base 1, and a first d...

Embodiment 2

[0052] A vertical load test and detection method of an anti-floating engineering pile disclosed by the present invention comprises the following steps:

[0053] S1. Install the detection device, and make the lifting frame above the anti-floating engineering pile 14, and use the first driving mechanism 7 to adjust the angle of the crossbeam 3, so that the adjustment crossbeam 3 is in a horizontal state.

[0054] Manually mark the center point on the upper end surface of the anti-floating engineering pile 14, use the second driving mechanism 9 to adjust the position of the lifting base frame 4, make the alignment part below the lifting base frame 4 align with the marking point of the anti-floating engineering pile 14, and The connecting frame 5 is fixedly connected with the upper end of the anti-floating engineering pile 14 , and the connecting frame 5 is connected with the lifting base frame 4 using a steel cable 12 .

[0055] S2. Use the hydraulic jack 6 to apply a vertical ja...

Abstract

The invention relates to the technical field of anti-floating pile quality detection, in particular to an anti-floating engineering pile vertical load test detection device and method. The detection device comprises a first supporting seat, a second supporting seat, a cross beam, a lifting base frame, a connecting frame and a jacking mechanism, the first supporting seat and the second supporting seat are symmetrically arranged on the two sides of an anti-floating engineering pile; a horizontal detection piece is arranged on the cross beam, one end of the cross beam is hinged to the first supporting seat, a first driving mechanism for driving the cross beam to rotate is arranged between the other end of the cross beam and the second supporting seat; the cross beam is sleeved with a slidingsleeve, the cross beam and the sliding sleeve are provided with a second driving mechanism for driving the sliding sleeve to move; the lifting base frame is slidably connected to the sliding sleeve, the center lines in the vertical direction of the lifting base frame and the sliding sleeve are collinear, an alignment piece is arranged in the center of the lower surface of the sliding sleeve; the connecting frame is fixedly arranged at the upper end part of the anti-floating engineering pile and is connected with the lifting base frame through a steel cable; and the jacking mechanism is arranged between the sliding sleeve and the lifting base frame and connected with a detection box. The anti-floating engineering pile vertical load test detection device has the advantage of being more accurate in detection.

Description

technical field [0001] The invention relates to the technical field of quality detection of anti-floating piles, in particular to a vertical load test detection device and method for anti-floating engineering piles. Background technique [0002] With the rapid development and utilization of underground space in the construction industry, more and more buildings are subjected to floating loads. In order to offset the effect of floating loads in the project, anti-floating pile foundations will be installed underground. This kind of vertical anti-floating piles It is called anti-floating engineering pile. In order to determine the vertical uplift ultimate bearing capacity of the anti-floating engineering piles and determine whether the vertical uplifting bearing capacity meets the design requirements, it is usually necessary to conduct a vertical load test on the anti-floating engineering piles. [0003] In the prior art, the detection device for vertical load test of anti-flo...
