[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. During construction, pipe piles are needed as the foundation. Pipe piles are divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles, prestressed concrete pipe piles, prestressed concrete thin-walled pipe piles, and high-strength prestressed concrete pipe piles. Pre-tensioned prestressed pipe piles are a kind of hollow cylindrical slender concrete prefabricated components made by pre-tensioning prestressing technology and centrifugal forming method. They are mainly composed of a cylindrical pile body, an end plate, and a steel sleeve. Before the pipe pile operation, a hammer test is required for the environment of the pipe pile installation test area to facilitate the subsequent installation of pipe piles. The hammer test is an impact test in which a heavy hammer is dropped from a gradually increasing height until the heavy hammer produces a specific deflection.

The original soil restraint device includes original soil, a top cover, a first half-membrane, a second half-membrane, a pipe clamp, a rigid base, a vertical pole and a nut. The hammering device is composed of a handle, a guide rod, a core hammer, a hammer pad and a probe with a scale connected in sequence from top to bottom. The first half-membrane and the second half-membrane are fixed by the pipe clamp. The original soil is placed in the cavity surrounded by the first half-membrane and the second half-membrane and placed on the rigid base. The vertical pole is provided on the rigid base, and the top of the vertical pole is provided with a thread. A top cover is placed on the top of the original soil, and the top cover passes through the vertical pole and is fixed by a nut. The device has a simple structure and is easy to operate. It can not only ensure the accuracy of the test results, but also observe the impact of piling on the surrounding rock and soil, providing a reference for actual construction."

[0004] The above patent will require taking out soil samples from the test area. During the process of taking out and transporting, moisture will be lost and the soil samples from the test area may become loose, thus affecting the test data.
