Description

Foundation pile detection device

Technical Field

The utility model relates to a building engineering quality detects technical field, specifically is a foundation pile detection device.

Background

The foundation pile detection mainly judges whether the foundation pile is qualified or not by testing the integrity and the bearing capacity of the engineering pile, wherein the bearing capacity of a pile body of most foundation piles is generally the vertical compression-resistant bearing capacity of a single pile, the vertical pressure is gradually applied to the top of the foundation pile, and the settlement of the top of the foundation pile along with the time is observed in real time, so that the vertical compression-resistant bearing capacity of the foundation pile is determined. At present, most methods for detecting the vertical compression resistance bearing capacity of a foundation pile in the field of Chinese constructional engineering are to stack a plurality of concrete balancing weights on a bearing platform above the top of the foundation pile to form a pressure carrier, then observe the settlement of the pile top, and indicate that the vertical compression resistance bearing capacity of the foundation pile meets the requirements as long as the settlement of the pile top is within a specified range, namely a single-pile vertical compression resistance static load test; the test method is the most intuitive and reliable test method for detecting the vertical compression bearing capacity of the foundation pile which is generally accepted at present.

In the vertical resistance to compression static load test of foundation pile, the counter weight that provides vertical pressure mainly uses the concrete balancing weight, and the stability of loading is piled to the concrete balancing weight is also especially important at hoist and mount, test process. At present, the concrete balancing weights designed by some detection mechanisms and related building engineering enterprises have differences, but most detection mechanisms adopt a mode of directly stacking the concrete balancing weights on a stacking platform without any protective measures. The base stress in the stacking process is increased, and the situations of field subsidence, counterweight inclination instability and the like caused by the influence of various factors in the test process often occur. The concrete balancing weight is heavy, bulky itself, and this makes in the experimental process of actual static load, and the heap of concrete balancing weight carries and has certain difficulty and danger, also influences the safety condition who detects the operation process.
