Device for monitoring soil plug lifting height of prestressed pipe pile in hydrostatic process

Abstract

The invention discloses a device for monitoring soil plug lifting height of a prestressed pipe pile in hydrostatic process. The device comprises a measure instrument, a fixed disc, a multiturn potentiometer, a synchronous wheel, a synchronous belt, a first counterweight and a second counterweight. The fixed disc is provided with fixing legs, the multiturn potentiometer is fixed on the fixed disc, the synchronous wheel is inlayed on the multiturn potentiometer, the synchronous belt is twined on the synchronous wheel, the first counterweight and the second counterweight are respectively arranged at the two ends of the synchronous belt, the weight of the first counterweight is greater than the weight of the second counterweight, and the measure instrument is connected with the multiturn potentiometer. By the device, the change of the soil plug lifting height of the prestressed pipe pile in the hydrostatic process can be accurately monitored in real time. The device is simple in structure and clever in design, low in production cost, and high in data reliability.

Description

technical field [0001] The invention relates to a device for monitoring the rising height of a soil plug during the static pressure process of a prestressed pipe pile. Background technique [0002] In the prior art, there is no device capable of monitoring the rising height of the soil plug in the pile cavity during the pile driving static pressure process. The general practice in engineering is to measure the final rising height of the soil plug with a tape measure after the piling is completed. The real-time monitoring of the rising height of the soil plug can clarify the whole process of the rising of the soil plug during the piling process, the growth of the soil plug height when the pipe pile is driven into different types of soil layers, and the composition of the bearing capacity of the pipe pile. , to verify and revise the design of the pile bearing capacity. [0003] Therefore, a device for monitoring the rising height of the soil plug during the static pressure pr...
