Pile foundation detection device and method for constructional engineering supervision

Abstract

The invention discloses a pile foundation detection device and method for constructional engineering supervision in the technical field of engineering supervision. The device comprises a bottom plate,the bottom of the bottom plate is fixedly connected with a horizontal adjustment mechanism, the horizontal adjustment mechanism comprises a six-rod adjustment nut and a U-shaped frame, and the middleof the top of the bottom plate is fixedly connected with a positioning mechanism. The positioning mechanism comprises an adjusting rod, L-shaped connecting rods, a clamping cross rod, an extrusion cross rod and a rotating connecting rod, the top of the bottom plate is fixedly connected with a lifting mechanism, the lifting mechanism comprises a support, a rope winding base and a rope winding roller, and the left side of a pile foundation is fixedly connected with a detection device. Through the combined action of the adjusting rod, the L-shaped connecting rods, a positioning ring and the clamping cross rod, on one hand, the to-be-detected pile foundation, a lifted heavy hammer and a steel wire rope for hoisting the heavy hammer are kept at the same axis position, the detection accuracy isimproved, and on the other hand, the lifted heavy hammer is rapid and stable, and the detection waiting time is shortened.

Description

technical field [0001] The invention relates to the technical field of engineering supervision, in particular to a pile foundation detection device and method for construction engineering supervision. Background technique [0002] Pile foundation testing is divided into pre-construction and post-construction testing of pile foundations: before construction, testing of testing piles that provide a basis for design, mainly to determine the ultimate bearing capacity of single piles; after construction, testing of engineering piles that provide basis for acceptance, mainly Carry out single pile bearing capacity and pile body integrity testing, the main methods of pile foundation testing include static load testing, core drilling method, low strain method, high strain method, acoustic transmission method and so on. [0003] Some invention cases of pile foundation detection devices and methods for construction engineering supervision are disclosed in the prior art. The Chinese pat...

Problems solved by technology

[0006] The purpose of the present invention is to provide a pile foundation detection device and method for construction engineering supervision, to solve the above-mentioned background technology proposed in the current high strain method pile foundation dynamic detection, the positioning of the weight and pile foundation is estimated by manual visual inspection There is no clamping mechanism to stabilize the heavy hammer after it is lifted. On the one hand, it cannot ensure that the heavy hammer is concentric with the pile foundation, which reduces the accuracy of detection. On the other hand, it cannot make the lifted heavy hammer fast and stable, which increases the stability of the heavy hammer. waiting time problem
