Problems solved by technology
[0005] The purpose of the present invention is to provide a locator for hole position review to alleviate the situation in the prior art that in order to reduce the deviation of the pile foundation hole position during the pile foundation construction process, it is necessary to use the measurement repeatedly during the pile foundation construction process. The stakeout method determines the center position of the pile foundation to review the pile position, but the process of measurement and stakeout is cumbersome, resulting in a large amount of review work and low work efficiency technical problems

Embodiment
[0033] like figure 1 As shown, the locator for hole position review provided in this embodiment includes a first marking rod 1 and a second marking rod 2 . The first marking rod 1 and the second marking rod 2 are connected and arranged at an included angle. The first marking rod 1 is provided with a first marking point, and the distance between the position where the first marking rod 1 and the second marking rod 2 are connected and the first marking point is not less than the radius of the hole to be checked. The second marking rod 2 is provided with a second marking point, and the distance between the position where the second marking rod 2 is connected to the first marking rod 1 and the second marking point is not less than the radius of the hole to be reviewed.
[0034] In the process of using the hole position review locator provided in this embodiment, first align the connection between the first marking rod 1 and the second marking rod 2 with the hole center that has b...

The invention provides a positioner for hole site rechecking, and relates to the technical field of construction tools. The positioner for hole site rechecking comprises a first marking rod and a second marking rod, wherein the first marking rod and the second marking rod are connected and are arranged in an included angle mode; the first marking rod is provided with a first marking point, and the distance between the position where the first marking rod and the second marking rod are connected and the first marking point is not smaller than the radius of a hole site to be rechecked; and the second marking rod is provided with a second marking point, and the distance between the position where the second marking rod and the first marking rod are connected and the second marking point is not smaller than the radius of the hole site to be rechecked. According to the positioner, the technical problems that in the prior art, in order to reduce the deviation of the pile foundation hole site in the pile foundation construction process, the central position of a pile foundation needs to be determined by utilizing a measuring and lofting mode for multiple times in the pile foundation construction process so as to recheck the pile position, but the measuring and lofting process is tedious, so that the rechecking workload is large, and the working efficiency is low are solved.
Description
technical field [0001] The invention relates to the technical field of construction tools, in particular to a locator for hole position review. Background technique [0002] In the construction of highway, railway and municipal engineering, the construction quality of bridge pile foundation is very important. [0003] When constructing the pile foundation, it is necessary to measure the stake out on the ground to mark the position of the pile foundation, and then cast the lock for protecting the pile position at the mark of the pile position (the lock usually has a center corresponding to the shape and size of the pile foundation. Through-hole concrete structure), after the lock construction is completed, the hole digging construction is carried out, after the pile hole is formed, the pile foundation reinforcement cage is installed, and then the concrete is poured, and the pile foundation can be formed after the concrete is formed. [0004] Due to the errors in the measurem...
