Compaction degree sensor, dynamic compaction machine and compaction degree detection method

Abstract

The invention discloses a compaction degree sensor, a dynamic compaction machine and a compaction degree detection method, and relates to the field of engineering machines. The compaction degree sensor comprises an accelerometer and a controller. The accelerometer collects the acceleration of a pounder in real time and sends the acceleration to the controller. The controller determines the compaction energy acting time of the pounder through comparison of the acceleration of the pounder and the preset acceleration threshold value and calculates the compaction degree of a soil body through the utilization of the inverse ratio relational expression of the compaction degree and the compaction energy acting time and according to the compaction energy acting time of the pounder. According to the compaction degree sensor, the dynamic compaction machine and the compaction degree detection method, the compaction energy acting time of the pounder is determined according to the pounder acceleration collected in real time, accordingly, the compaction degree of the soil body is calculated, and the compaction degree of the soil body can be automatically, accurately and comprehensively detected in real time; and the phenomenon of insufficient compaction or excessive compaction due to human factors is reduced, and the consistency of the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a compaction degree sensor, a dynamic compaction machine and a compaction degree detection method. Background technique [0002] The dynamic compaction machine is a kind of construction machinery equipment widely used in foundation treatment at present. The dynamic tamping machine uses lifting equipment to raise the rammer to a certain height, and then releases the rammer to let it fall freely, and uses the strong impact force generated when the rammer falls to compact the soil, thereby improving the strength of the foundation and reducing possible subsidence of the foundation. The object of the dynamic compaction machine is the foundation soil, and the purpose is to improve the strength and uniformity of the foundation soil. Therefore, the degree of compaction is one of the key indicators of the construction quality of the dynamic compaction machine. [0003] At present, ...
