Title:
SOIL PRESSURE AND DISPLACEMENT MONITORING SYSTEM AND METHOD FOR MINIATURE STEEL PIPE PILE BODY
Document Type and Number:
WIPO Patent Application WO/2021/017984
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of pile foundation engineering field tests, relates to a soil pressure and a displacement monitoring system and method for miniature steel pipe pile body, the predetermined positions on the outer side of the pile body are drilled and sensor metal protective shells with the thickness slightly smaller than that of XY-TY02A resistance type miniature soil pressure gauges are welded, the XY-TY02A resistance type miniature soil pressure gauges are attached to the pile body, transmission lines of the XY-TY02A resistance type miniature soil pressure gauges are led out from the inside of a steel pipe pile through sensor mounting holes to communicate with a data acquisition system, and a reflector base is welded to the predetermined position of the miniature steel pipe pile for pasting a reflector to realize displacement monitoring. The device has a simple structure, operation is simple and convenient, reliability and stability are achieved, measurement accuracy and survival rate are high, the cost is low, manpower, material resources and time are saved, the soil pressure change of miniature steel pipe pile support in a rock and soil foundation pit can be monitored in real time, test data is provided for a miniature steel pipe pile support theory for on-site monitoring in rock and soil foundations, and reference value is provided for engineering practice.
