Embodiment Construction

[0028] Examples see figure 1 As shown, this simple hole detector includes a fixed cross 1, a falling cross 3, a suspension wire 4 and a suspension wire reel 8 for winding the suspension wire. The fixed cross 1 is hinged into a cross shape by two upper arms 1.1, and two There is a threading hole 2 at the hinge of the upper arm, and the surface of the threading hole 2 is smooth. The falling cross 3 is hinged into a cross shape by two lower arms 3.1, and the hinge axis 3.3 of the falling cross 3 is symmetrically distributed. Four balance adjustment bolts 7, the suspension wire 4 is a wear-resistant suspension wire, the upper end is wound and connected with the suspension wire reel 8, the lower end of the suspension wire 4 passes through the threading hole 2 of the fixed cross 1, and is respectively connected with four balance adjustment bolts 7 at the four ends The balance suspension wire 4.2 is centrally connected, and the length of the balance suspension wire 4.2 can be adjuste...

Abstract

The invention relates to a simple hole verifier and an application method thereof. The simple hole verifier comprises a fixed cross, a falling cross and a suspension wire joining the fixed cross and the falling cross, wherein the fixed cross is formed by hinging two upper arms, the hinged position of the two upper arms is provided with a threading hole, the lower surface of each upper arm is symmetrically provided with an upper arm extension rod about the center, the falling cross is formed by hinging two lower arms, each lower arm is symmetrically provided with a balance adjusting bolt by adopting a hinge shaft as a center, two end parts of each lower arm are respectively provided with a second adjusting screw and a pair of lower arm extension rods which are fixed below the lower arms. The simple hole verifier is simple in structure, low in cost, flexible to use and simple and practical in operation process; a function for measuring aperture of a pile hole and a function for measuring the verticality of the pile are integrated, so that flexibility in adjustment can be realized according to the on-situ situation, not only can the accuracy in measurement be guaranteed, but also the measurement working efficiency can be guaranteed, and the success in work can be favored. The simple hole verifier can be widely used for measuring the aperture and the verticality of the pile hole.

Description

technical field [0001] The invention relates to a measuring tool for building construction and a using method thereof, in particular to a measuring tool for pile hole diameter and verticality and a using method thereof. Background technique [0002] For a long time, the traditional measurement of pile hole diameter and pile verticality mainly uses pendant hammer and steel ruler. The measurement process is slow and complicated, and the measurement data error is relatively large; The hole diameter design cannot measure the hole diameter and verticality at the same time, and this kind of tool has a complex structure and complicated operation process, which cannot guarantee work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a simple hole inspector and its use method, to solve the technical problem of measuring pile hole diameter and verticality at the same time; and to solve the problems of simplifying the measurement proces...
