[0002] Pile foundation engineering is widely used in the fields of construction, bridges, elevated roads, high-speed rail construction, etc. Domestic and foreign testing workers are studying reliable methods for testing the vertical compressive bearing capacity of single piles. At present, static load tests cannot be completely replaced by other testing methods due to their high reliability of test results. With the continuous and rapid development of the national economy, more and more buildings with super-high-rise and large-span designs are being adopted, and the requirements for the vertical compressive bearing capacity of single piles in pile foundations are becoming greater and greater, which puts higher requirements on the vertical compressive static load test capacity of single piles.

[0003] At present, during the static load test of traditional pile foundations, a bearing plate needs to be placed between the jack and the top surface of the pile to transfer the top pressure provided by the upper counterweight to the pile body.

[0004] However, traditional bearing plates only consider the use of steel plates with greater rigidity, without considering the axial alignment between the jack, steel plate and pile top. In actual inspections, installation is generally based on manual experience and visual inspection, which can easily lead to eccentricity when the top weight pressure is transmitted to the pile body, affecting the accuracy of the inspection data.

[0008] Wherein, the static load detection auxiliary centering pressure plate device also includes a guide component, and the guide component is arranged in the jack fixing position.

[0009] Among them, the guiding assembly includes two limit sleeves, two guide arc blocks and two springs. The two limit sleeves are symmetrically arranged in the fixed position of the jack. The two ends of each spring are respectively connected to the loading and unloading grid and the corresponding limit sleeve. Each guide arc block is respectively connected to the corresponding limit sleeve and is respectively located above the limit sleeve.
