Description

Technical Field

[0001] The present invention relates to a detection device and a use method, in particular to a detection device and a use method for a pile column of a Yunba track being in a broken pile head state. Background Art

[0002] When pouring cast-in-place piles, the top elevation of the cast-in-place piles should be 0.8-1.0m higher than the designed pile top elevation to ensure the strength of the pile head concrete. However, the pile head part that is higher than the designed pile top elevation must be chiseled off during the subsequent construction process. The work of chiseling off this part of the pile head concrete is called "breaking the pile head". In order to ensure the safety performance of the Yunba track, it is necessary to perform parameter detection on the Yunba track piles in the broken pile head state. Therefore, the detection device for the Yunba track piles in the broken pile head state is an important construction device. Among the existing detection devices for the Yunba track piles in the broken pile head state, there is no detection device for the Yunba track piles in the broken pile head state. The strength of the Yunba track piles is tested after the broken pile heads are completed. Since the parameters of the state of the Yunba track piles in the foundation are not detected, it is impossible to provide data support for the comprehensive evaluation of the pile head breaking method. The present invention uses the technical feature of detecting the comprehensive parameters affecting the pile column 1 during the pile head breaking process to effectively explore and study the technical problem of strength testing of the Yunba track pile column after the pile head is broken. The statements here only provide background technology related to the present invention and do not necessarily constitute prior art. The technical solution of the present invention is made based on the technical briefing document provided by the applicant on June 15, 2024, which solves actual technical problems in the work process, and the existing technical problems, technical features and technical effects in the similar patent literature and background technology obtained through retrieval.
