Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the drawings and specific embodiments:

[0030] A device for inspecting the quality of digging and filling piles, such as figure 1 with figure 2 As shown, the main ruler 1, the auxiliary ruler 2, the beam emitter 3 and the legs for supporting the main ruler and the auxiliary ruler are included, wherein the legs include two main legs 41 and one auxiliary leg 42. The two ends of the main ruler 1 are respectively installed on the main leg 41; one end of the sub ruler 2 is hinged to the middle of the main rule 1, and the other end is installed on the sub leg 42; the beam transmitter 3 is suspended on the sub ruler 2 by a suspension line on.

[0031] The main leg 41 includes a support seat and a stud perpendicular to the upper surface of the support seat. Two nuts are arranged on the stud at intervals, and the end of the main ruler is located between the two nuts. The structure of the auxiliary...

Abstract

The invention discloses a device for detecting the quality of a hole formed in a hole-digging cast-in-place pile. The device comprises a main scale and an auxiliary scale hinged to the middle of the main scale, wherein landing legs used for adjusting the main scale to be in a horizontal state are arranged on the two ends of the main scale respectively, one end of the auxiliary scale is hinged to the middle of the main scale, a landing leg used for adjusting the auxiliary scale to be in a horizontal state is arranged at the other end of the auxiliary scale, and a light beam emitter used for emitting light beams downwards vertically is suspended on the auxiliary scale. The device for detecting the quality of the hole formed in the hole-digging cast-in-place pile is simple in structure, convenient to use and free of the influence of airflow in hole in the pile during measurement, the complicated operation of lifting and putting down of a hammer is eliminated, the precision is high, and the speed is high.

Description

Technical field [0001] The invention relates to a pile foundation construction auxiliary device, in particular to a quality detection device for digging and filling piles. Background technique [0002] Pile foundation is a supporting structure commonly used in infrastructure construction such as railways, bridges, and iron towers. It generally includes a concrete pile embedded in the pile hole and a concrete cap located above the pile. Bridges, iron towers and other buildings are built on concrete On the platform. Because the pile foundation can not only ensure the strength and bearing capacity, but also has the advantages of low cost, economy and practicality, so it is widely used in the field of engineering construction. [0003] Pile foundations can be divided into two categories: cast-in-place piles and precast piles according to the manufacturing process. The cast-in-place piles can be further divided into sinking pipe piles, bored piles and digging and cast-in-place piles ac...
