Description

Technical Field

[0001] The present invention relates to the field of anti-floating anchor bolt detection, and specifically relates to an anti-floating anchor bolt detection device and a detection method. Background Art

[0002] An anti-floating anchor bolt is a kind of anti-floating measure for the underground structure of a building project. It refers to a structural member set to resist the upward displacement of the building thereon. The anti-floating anchor bolt is used to resist the upward displacement of the building caused by the buoyancy of groundwater. In areas with a relatively high groundwater level, the foundation of a building may be affected by the buoyancy of groundwater, resulting in structural instability. The anti-floating anchor bolt connects the building foundation with the foundation rock layer to form an integral body, effectively resisting the upward buoyancy of groundwater and ensuring the stability of the building.

[0003] By detecting the pull-out bearing capacity and deformation of the anchor bolt, the anti-floating capacity of the underground building is evaluated to ensure its stability under the action of groundwater buoyancy. The purpose is to check whether the construction quality meets the design requirements. By applying a certain load to the anchor bolt and observing its displacement and deformation, it is judged whether the bearing capacity and stability of the anchor bolt meet the requirements.

[0004] For example, the anti-floating anchor bolt detection device and detection method for underground space with the publication number CN114527006B, although greatly reducing the manual operation intensity, and having simple operation and convenient use, only requiring an external hexagonal wrench to complete the fixation of the hydraulic cylinder body and the fixed shaft, the fixation between the anti-floating anchor bolt and the device is unstable. When the device provides an upward pulling external force to the anti-floating anchor bolt, the anti-floating anchor bolt is prone to slide and disengage from the device, so that the performance of the anti-floating anchor bolt cannot be correctly detected, and there is a certain danger.

Clamping sleeves are clamped inside the two semi-circular holes. Semi-circular washers are fixedly connected to the upper surfaces of the two clamping sleeves. The same conical block is clamped inside the two semi-circular washers. The upper end of the conical block is fixedly connected to a pressure plate. A plurality of arc-shaped openings are opened on the surface of the pressure plate. Arc grooves are opened at both ends of the inner walls of the two semi-circular inner cylinders. Two hydraulic cylinders are clamped inside the four arc grooves.

[0007] Specifically, the pressing-down component includes two threaded cylinders, two jacks opened on the outer walls of the upper ends of the two semi-circular outer cylinders, and two through holes opened on the upper surface of the pressure plate. The two threaded cylinders are fixedly connected to the centers of the inner walls of the upper ends of the two semi-circular outer cylinders. Threaded rods are threadedly connected inside the two threaded cylinders. The upper ends of the two threaded rods are inserted into the two jacks. Push rods are fixedly connected to the upper ends of the two threaded rods. The two push rods are inserted into the two through holes. Fixed rings are fixedly sleeved on the upper end surfaces of the two push rods. Cylinders are fixedly connected to the upper ends of the two push rods.

At the same time, the bent anti-floating anchor rods can increase the friction force with the semi-circular washer, prevent the anti-floating anchor rods from sliding between the cone block and the semi-circular washer, and prevent the sliding of the anti-floating anchor rods from affecting the accuracy of the detection results.

[0014] (2) For the anti-floating anchor rod detection device of the present invention, by inserting the threaded rod into the through hole and the jack hole in sequence, then rotating the rotating rod to drive the cylinder to rotate, the cylinder drives the push rod to rotate, the push rod drives the threaded rod to rotate, so that the threaded rod is threadedly connected in the threaded cylinder. When the threaded rod rotates, it will drive the push rod to move downward. The push rod pushes the pressure plate to move downward through the fixing ring, making the downward movement of the pressure plate more labor-saving. Description of the drawings
