Concrete pile foundation bearing capacity detection device

Abstract

The invention discloses a concrete pile foundation bearing capacity detection device. The concrete pile foundation bearing capacity detection device comprises paired supporting plates, wherein universal wheels are rotationally installed on the two sides of the bottom ends of the paired supporting plates, and a same top plate is fixedly installed at the top ends of the paired supporting plates; paired first hydraulic cylinders are fixedly installed on the top plate, and a same lifting base is fixedly installed at the free ends of the paired first hydraulic cylinders; two openings are formed in the lifting base, and the two supporting plates penetrate through the two openings; and a rotating shaft is rotationally installed on the top plate, scale lines are fixedly installed on the two sides of the rotating shaft correspondingly, and the two scale lines are wound on the rotating shaft. According to the concrete pile foundation bearing capacity detection device, a pile foundation is right opposite to the center positions of abutting bases in an annular array shape, the abutting bases abut against the pile foundation under the torsion effect of a torsional spring to adjust the lifting base to move downwards, a pressing plate is directly aligned to abut against the pile foundation, an extrusion cushion is controlled to press the abutting bases, the position of the detection device is limited, in the abovementioned way, the device is rapidly positioned, and the situation that a large amount of detection time is wasted due to the fact that the relative positions of a pressing piece and the pile foundation are determined is avoided.

Description

technical field [0001] The invention relates to the technical field of pile foundation detection, in particular to concrete pile foundation bearing capacity detection equipment. Background technique [0002] According to the relevant regulations of the Ministry of Transport, the bridge under construction or the deep soft foundation treatment of the roadbed must test the vertical compressive bearing capacity of its foundation piles or flexible piles (such as: gravel piles, high-pressure rotary grouting piles, deep mixing piles, etc.) , to ensure the safe operation of bridges and subgrade soft foundations after opening to traffic. The general pile foundation testing device cannot ensure flexibility when moving and stability when standing still. In addition, pre-positioning is required when testing different pile foundations sequentially. Otherwise, it will waste a lot of detection time to determine the relative position of the pressure member and the pile foundation. Differen...

Problems solved by technology

The general pile foundation testing device cannot ensure flexibility when moving and stability when standing still. In addition, pre-positioning is required when testing different pile foundations sequentially. Otherwise, it will waste a lot of detection time to determine the relative position of the pressure member and the pile foundation. Different embedding depths affect its bearing capacity performance, so it is necessary to determine the embedding depth of different pile foundations, and the additional use of measuring tools will increase the complexity of the operation. In view of this, we propose a concrete pile foundation bearing capacity testing equipment to solve the above problems
