Abstract

The invention discloses a force measurement pile cap. The force measurement pile cap is fixed to a pile located in a supporting layer and comprises a bottom board, a loadometer, a top board and a pile cap body which are distributed from bottom to top; the lower side surface of the bottom board is fixed to the pile; the bottom of the loadometer is fixed to the upper side surface of the bottom board, and the top of the loadometer is fixed to the lower side surface of the top board; the pile cap body is arranged on the upper side surface of the top board; the force measurement pile cap further comprises a vibration string, a cable and a reading device; and the loadometer is connected with the reading device sequentially through the vibration string and the cable. By means of the force measurement pile cap, load transmitted to a single pile can be accurately measured, and therefore, the accurate bearing load of earth among piles is obtained; the single-pile bearing load in a rigid pile or flexile pile composite foundation can be monitored, the reliable actual measurement basis is provided for study of a design theory of the pile-foundation composite foundation, and accordingly, the pile-foundation composite foundation optimal design which is technically reliable and low in construction cost can be obtained; and the security and stability of the pile-foundation composite foundation can be guaranteed by monitoring the change rule of the single-pile load in the construction process.

Description

technical field [0001] The invention relates to the technical field of pile foundation quality detection in civil engineering, in particular to a force-measuring pile cap. Background technique [0002] For composite foundations, such as pile-net composite foundations, the load bearing between piles and the soil between piles is two important indicators. At present, there is no method to directly measure the pile load and the soil load between piles, and it is generally calculated by measuring the earth pressure. Since the measurement accuracy of the earth pressure is affected by many factors, the earth pressure varies greatly at different horizontal positions and height positions; the earth pressure at the center of the pile cap, and the earth pressure around it may be affected by the effect of the reinforced cushion And there are obvious differences. Therefore, it is difficult to obtain more accurate pile bearing load and soil bearing load between piles by measuring the e...
