Device and method for rapidly and precisely measuring perpendicularity of drilled pile body

Abstract

The invention relates to the field of control over the perpendicularity of drilled pile bodies, in particular to a device and method for rapidly and precisely measuring the perpendicularity of a drilled pile body. By applying the device, the problem that the pile-diameter perpendicularity after hole forming of an existing drilled pile cannot be measured effectively can be solved, the blanks of theprior art are filled up, and the construction quality of the drilled pile is improved. The device comprises a centered connecting plate and four measuring rulers fixed to the centered connecting plate and having measuring ruler scale values, the central lines of two of the measuring rulers are located on the same straight line and are in the same direction as the transverse radial direction of asteel casing, the central lines of the other two measuring rulers are located on the same straight line and are in the same direction as the longitudinal radial direction of the steel casing, and thetwo measuring rulers located on the transverse radial direction of the steel casing are perpendicular to the two measuring rulers located on the longitudinal radial direction of the steel casing. Themeasuring process of the method is simple, the perpendicularity can be measured rapidly and precisely, operability is high, the measuring result is more accurate, and the construction quality of the pile body is ensured. The manufacturing cost of the complete device is low, recycling can be achieved, and thus the construction cost is lowered.

Description

technical field [0001] The invention relates to the field of verticality control of bored pile bodies, in particular to a device and method for quickly and accurately measuring the verticality of bored pile bodies. The application of the device can solve the problem that the verticality of the pile diameter cannot be effectively measured after the existing bored piles are formed, fill in the gaps in the prior art, and improve the construction quality of the bored piles. Background technique [0002] The verticality of the pile body is one of the important indicators to measure the construction quality of the bored pile. During the construction of the bored pile, if the verticality of the borehole is too large, the reinforcement cage and the conduit cannot be placed, which will bring many troubles to the construction. If the borehole deflection is too large, the effective bearing capacity of the foundation pile will be weakened, resulting in uneven settlement of the upper par...
