[0005] The upper frame and lower frame are rectangular, and smaller than lower frame.

[0006] The short side of the lower frame is equipped with mounting groove, the mounting groove is rectangular groove, and the leg lower end is fixedly installed in the mounting groove.

[0007] The leg is triangular steel.

[0008] The intermediate support frame is equipped with a row of rectangular holes, and the upper and lower ends of the intermediate support frame are welded in the middle of the long side of the upper frame and lower frame, and the two sides of the intermediate support frame are equipped with X-shaped reinforcing rib, one side of the X-shaped reinforcing rib is welded on the leg, and the other side is welded on the intermediate support frame.

[0009] The upper frame is not less than the bottom area of high strain guide frame.

[0010] The utility model provides a kind of auxiliary device for high strain detection of foundation pile, its beneficial effect lies in, the stability of original high strain guide frame is increased, so that guide frame is more safe and reliable;High strain guide frame height is increased, and then the height of weight hammering is increased, so that hammering energy coverage is more extensive, and the situation that the higher potential energy is needed is adapted to the higher bearing capacity.

[0016] With reference to the drawings, in combination with an embodiment, a kind of auxiliary device for high strain detection of foundation pile provided by the utility model is described in detail.

[0017] EMBODIMENT

[0018] Referring to Figs. 1-3 , a kind of auxiliary device for high strain detection of foundation pile of this embodiment, install at the bottom of high strain guide frame 1, including upper frame 2, lower frame 4, leg 3 and reinforcing support, the upper frame 2, lower frame 4 are set up to each other, the leg 3 upper end is welded in the four corners at the bottom of upper frame 2, the leg 3 lower end is fixed on lower frame 4, the long side side between the upper frame 2 and lower frame 4 is equipped with reinforcing support, and the short side side between the upper frame 2 and lower frame 4 is equipped with inlet 9, to facilitate entering installation sensor and position adjustment etc., the reinforcing support includes X-shaped reinforcing rib 5 and intermediate support frame 6, the intermediate support frame 6 is the bracket with hole.

[0019] The upper frame 2, lower frame 4 are all rectangle, and smaller than lower frame, increase the stability of auxiliary device.

[0020] The short side of the lower frame 2 is equipped with mounting groove 8, the mounting groove 8 is rectangular groove, the lower end of leg 3 is fixedly installed in mounting groove 8, and it is simple and convenient and reliable to install.

[0021] The leg 3 is triangular steel, simple structure, convenient to weld firmly.

[0022] The intermediate support frame 6 is provided with a row of rectangular holes 7, the upper and lower ends of the intermediate support frame 6 are respectively welded to the middle of the long side of the upper frame 2 and the lower frame 4, both sides of the intermediate support frame 6 are provided with X-shaped reinforcing ribs 5, one side of the X-shaped reinforcing rib 5 is welded to the support leg 3, and the other side is welded to the intermediate support frame 6, thereby increasing the stability of the auxiliary device carrying higher hammering potential energy.
