Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a device for detecting the verticality of foundation piles in civil engineering. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and the pile base, is referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low-cap pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high-cap pile foundation.

[0003] After existing pile foundation construction is completed, the quality of the pile foundation needs to be inspected, including the verticality of the pile foundation. Currently, this is done by connecting a pendant to a hole in the pile foundation. The laser light at the end of the pendant then strikes a scale plate on the underside for inspection. However, during actual inspection, the pendant and its suspension rope can sway due to wind, affecting the accuracy of the inspection. Furthermore, drilling holes in the pile foundation is cumbersome. Therefore, we propose a device for inspecting the verticality of civil engineering pile foundations. Utility Model Content
