Manual hole digging pile quality control device and application method thereof

Abstract

The invention discloses a quality control device and a use method for artificially digging piles. The device is composed of a horizontal positioning frame, a central positioning rod and a pile aperture detection ruler; The center line of the hole pile is vertical; the center positioning rod is parallel and concentric with the center of the artificial hole pile; Concentric and perpendicularly intersecting; the upper end of the central positioning rod is perpendicularly intersected and consolidated with the horizontal positioning frame, and the lower end is perpendicularly intersected and consolidated with the pile aperture detection ruler; the invention is beneficial to accurately control the center displacement during the construction process of artificial excavation piles. , pile diameter, pile concentricity, pile hole verticality quality, can also be used as a quality inspection tool, economical and practical, with significant economic benefits.

Description

technical field [0001] The invention discloses a quality control device and a use method for manual digging piles, which are designed for controlling the hole quality of manual digging piles during construction, and belong to the technical field of construction quality detection. Background technique [0002] The pile position of the manual digging pile is determined by accurate measurement and setting out, and the manual digging pile is set out according to the aperture before excavation; the hole formation of the manual digging pile is carried out every 1 meter by manually installing the excavation line One-time retaining wall construction; since the excavation and retaining wall are carried out in sections every 1 meter, during the manual excavation pile construction, the offset of the center line of the pile hole, the verticality of the pile, the pile diameter, and the concentricity of each section are very important. Difficult to control; the existing control method is ...

[0002] The pile position of the manual digging pile is determined by accurate measurement and setting out, and the manual digging pile is set out according to the aperture before excavation; the hole formation of the manual digging pile is carried out every 1 meter by manually installing the excavation line One-time retaining wall construction; since the excavation and retaining wall are carried out in sections every 1 meter, during the manual excavation pile construction, the offset of the center line of the pile hole, the verticality of the pile, the pile diameter, and the concentricity of each section are very important. Difficult to control; the existing control method is to pull steel wires perpendicular to each other on the top of the pile hole, take the intersection point of the steel wires as the center point of the pile hole, hang a vertical line through this point, and use the vertical line as the center line of the pile hole, use Steel tape measures the distance from the vertical line to the hole wall to check the pile diameter and the offset of the centerline of the pile hole, the verticality of the pile, and the concentricity of each section. Since the positions of the mutually perpendicular steel wires set at the top of the pile hole are different each time, As a result, the results of each test have a large deviation. At the same time, because the vertical line is flexible, the measurement error with a steel tape is large, resulting in time-consuming, laborious, unstable and large errors in the quality control of manual excavation piles.
