Embodiment Construction

[0037] The following is attached Figure 1-8 The application is described in further detail.

[0038] The embodiment of the present application discloses a high strain detection device for foundation piles.

[0039] refer to figure 1 , the detection device includes a support frame 1, a weight 2 and a lifting mechanism 3, the weight 2 and the lifting mechanism 3 are both arranged on the support frame 1, the foundation pile 4 is pierced in the support frame 1, and the weight 2 is lifted by the lifting mechanism 3 Make the weight 2 impact on the foundation pile 4, thereby insert the foundation pile 4 into the ground.

[0040] see figure 1 and figure 2The support frame 1 includes a base 11, a number of support columns 12 vertically arranged on the base 11, and a bearing plate 13. When the support frame 1 is in use, the base 11 is fixedly connected to the ground, and the foundation pile 4 is penetrated on the base 11. The support columns 12 One end of the base is fixedly conn...

Abstract

The invention relates to a foundation pile high strain detection device, and belongs to the technical field of foundation pile detection. The foundation pile high strain detection device comprises a supporting frame, a heavy hammer and a lifting mechanism arranged on the supporting frame and used for lifting the heave hammer, wherein the heavy hammer comprises a bottom plate and at least one balancing weight connected to the bottom plate, and the lifting mechanism is connected to the heavy hammer. The counterweight blocks of the heavy hammer can be set according to the actual situation, the weights of the heavy hammer are different by adding different numbers of counterweight blocks, then the heavy hammer matches with foundation piles of different sizes, and the working efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of foundation pile detection, in particular to a high strain detection device for foundation piles. Background technique [0002] The high-strain method is to use a heavy hammer to impact the pile top, measure the velocity and force time-history curve of the pile top, and analyze the vertical bearing capacity of the single pile and the integrity of the pile through the analysis of the wave theory. [0003] The foundation pile detection device in the related art includes a support frame, a weight arranged on the support frame, and a lifting mechanism arranged on the support frame for lifting the weight. The weight is lifted by the lifting mechanism so that the weight hits the foundation pile, but The size of foundation piles will vary depending on the construction area, and the weight of the weight is generally fixed, so that the weight cannot be adapted to different foundation piles.
