A comprehensive operation parameter acquisition system of a dynamic compaction machine and its working method

Abstract

The invention discloses a complex dynamic compactor operation parameter collecting system and a working method thereof. The working method comprises the steps that the input end of a trigger is connected with a hammer hook; the output end of the trigger is connected with a GPS position information collecting module and a dynamic compactor operation parameter collecting module; the output end of the GPS position information collecting module and the output end of the dynamic compactor operation parameter collecting module are connected with a controller; the controller is further connected with a displayer, a memorizer and a timer; the timer begins timing automatically when the system is started; the trigger is started at the moment when the hammer hook is opened and closed, and shut down immediately after being started; and the GPS position information collecting module and the dynamic compactor operation parameter collecting module are triggered to work only at the moment when the trigger is started. The complex dynamic compactor operation parameter collecting system and the working method thereof have the beneficial effects that all or any one of a dynamic compaction construction quality parameter, a position parameter, a time parameter and other parameters can be automatically collected, and the dynamic compaction quality parameters are automatically collected and recorded.

Description

technical field [0001] The present invention relates to the technical field of engineering machinery, and in particular to a tamping machine including position information of tamping points, times of tamping, tamping energy (hammer weight, weight drop distance), tamping weight, cumulative tamping weight, number of tamping times, front and rear A system for collecting comprehensive operation parameters of a dynamic compaction machine such as the rest time of two compactions and a working method thereof. Background technique [0002] The dynamic compaction method is to drop a heavy hammer from a high place to impact and vibrate the roadbed, thereby increasing the strength of the foundation soil and reducing its compressibility. This method was initially only used to strengthen sandy soil and gravel soil foundation. After more than ten years of application and development, it has been applied to gravel soil, sandy soil, clay soil and silty soil with low saturation, and collapsi...

Problems solved by technology

This process is cumbersome and labor-intensive. However, it is impossible for the owner and the supervisor to supervise the quality of the whole process of dynamic compaction construction. Therefore, it is easy for the construction personnel to artificially miss the compaction, perform compaction without following the layout of compaction points, or insufficient compaction energy. , or the monitoring data provided is falsified, and the project quality is difficult to carry out effective supervision, which leads to serious project quality problems
