The most important parameter in the construction quality, the static load test of the pile foundation is a technology used in the engineering to detect the bearing capacity of the pile foundation. In the prior art, the jack is usually directly used and a simple auxiliary support is installed on the jack. During the load test, under the vertical load, if the jack on the upper surface is not placed horizontally and vertically, the resultant force of the jack will appear eccentric, and the existing auxiliary support is difficult to ensure the accurate position of the jack without reliable positioning. Therefore, the jack is easy to tilt under pressure, which interferes with the vertical load on the top of the pile, which not only affects the test results, but also increases the danger during the test. In severe cases, it will collapse and cause safety accidents and cause heavy losses. The coordination is not in place, and the use and operation are also very inconvenient.
