Description

Pile foundation allowable bearing capacity measuring device Technical Field The application relates to the field of pile foundation detection technology, in particular to a pile foundation allowable bearing capacity measuring device. Background The pile foundation is a deep foundation consisting of piles and pile caps (called caps for short) connected with the tops of the piles or a single pile foundation connected with the piles by the piles. Pile foundations are widely used in high-rise buildings. ‌ testing the allowable load bearing capacity of pile foundations is critical ‌ to ensure building safety and stability. The allowable load capacity refers to the maximum load capacity that can be borne per unit area of the foundation, and reflects the strength and stability of the foundation. Insufficient load bearing capacity, if allowed, may result in the building settling, tilting, or even collapsing. The utility model provides a detection device for building engineering pile foundation bearing capacity for "CN219219135U", it includes two I-shaped support frame, two equal fixed mounting in top of I-shaped support frame has two backup pads, two fixed mounting has two connecting plates between the backup pad, two fixed mounting has the slide bar between the connecting plate, two the outer wall of slide bar all slides and runs through there is the slider, and fixed mounting has same movable box between two sliders. According to the utility model, the weight can be quantitatively added into the movable box, so that the bearing capacity of the detected pile foundation is conveniently and clearly displayed, the weight can be conveniently and rapidly taken out after detection, and the next detection is convenient. However, in practice, when testing the allowable bearing capacity of the pile foundation, it is often judged by the depth of sinking caused by the load applied to the pile foundation in a static state. However, in this document, when a weight is added to the movable box, the weight falls into the movable box, and a vertical impact force is generated on the movable box. Under the impact force, the movable box can be subjected to instantaneous force to move downwards, so that the accuracy of the test result is lost. Therefore, the above patent has disadvantages.
