[0002] With the increasing demand for the construction of transmission line projects, improving construction efficiency has become the general direction of the industry's development. Due to the characteristics of optimizing construction technology according to the terrain of transmission lines, cast-in-place piles are used for one-time construction on-site. After the piles are formed, low-strain detection of the pile length and high-strain detection of the pile bearing capacity test are required. According to multiple on-site tests and trials, it is necessary to optimize the traditional high-strain detection device. In the prior art, when performing high-strain detection, the heavy hammer directly impacts the stressed component without an external isolation object, which easily causes deformation of the stressed component and damage to the top surface of the foundation. The utility model adopts a steel structure and strengthens the internal support frame to effectively and firmly support the impact force received by the upper stressed steel plate, and sets rubber pads to reduce the damage of the stressed component. Content of the Utility Model

The internal support frame is welded above to the upper stressed steel plate and below to the bottom protection foundation steel plate. The bottom protection foundation steel plate is provided with adjustable anchor bolt holes, and the rubber pad is arranged on the surface of the upper stressed steel plate.
[0006] The internal support frame is made of steel structure and is welded by I-beams, presenting a "field" shape.
[0007] The adjustable anchor bolt holes are oval and there are 4 of them, which are arranged on the bottom protection foundation steel plate.
[0008] Both the upper stressed steel plate and the bottom protection foundation steel plate are circular. The size of the upper stressed steel plate is larger than that of the bottom protection foundation steel plate, and the size of the rubber pad is larger than that of the upper stressed steel plate.
[0009] When conducting high-strain testing, the top surface of the foundation is connected through the adjustable anchor bolt holes provided on the bottom protective foundation steel plate. The anchor bolts can be adjusted and installed according to actual needs. The rubber pad is placed on the upper stress-bearing steel plate. When the heavy hammer hits the upper stress-bearing steel plate, the main piles of the foundation and the anchor bolts can be protected from being damaged by the impact force. The internal support frame is composed of I-beams, which can effectively and firmly support the impact force on the upper stress-bearing steel plate and prevent deformation. The utility model has a simple structure, is easy to disassemble and install, can be directly used for concrete top surface protection, and has a high reuse rate.
