Multi-functional dynamic penetration automatic recording system based on Internet of Things and test method

Abstract

The invention discloses a multi-functional dynamic penetration automatic recording system based on the Internet of Things and a test method. The multi-functional dynamic penetration automatic recording system based on the Internet of Things comprises a drilling machine supporting frame and a counting recording integrated device, and the system is configured with a central server and a data transmission system to realize synchronous and high-efficiency control over multiple drilling machine dynamic penetration tests. According to the disclosed test method, a standard penetration test and a conedynamic penetration test method are optimized, a rod length correction formula suitable for the standard penetration test and the cone dynamic penetration test is developed, programmed and input a counting processor and a computer. According to the multi-functional dynamic penetration automatic recording system based on the Internet of Things and the test method, the method is rigorous in structure, a counting module, a recording module, a data transmission module and a wireless communication module are integrated into a whole, the appearance is simple, use is convenient, automatic recordingof the number of hits can be realized, and count is accurate; and complexity of the dynamic penetration test in engineering investigation is reduced, and working efficiency of an in-situ test in geotechnical engineering investigation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering survey in-situ testing, in particular to a multifunctional dynamic penetrating automatic recording system and a test method based on the Internet of Things. Background technique [0002] Both the standard penetration test and the cone dynamic penetration test are dynamic penetration testing methods, which are two commonly used in-situ test methods for measuring various rock and soil layers on site. The physical state of soil, gravel soil, strongly weathered rock, etc., soil strength, deformation parameters, foundation bearing capacity, single pile bearing capacity, sand and silt liquefaction, and the possibility of pile formation are evaluated. Specifically: the standard penetration test uses a 63.5kg hammer, which falls freely from a height of 76cm. After a penetrating rod with a length of 51cm, an outer diameter of 5.1cm, and an inner diameter of 3.49cm is driven into the soil f...
