Dynamic compaction machine construction and operation parameter acquiring system and operating method thereof

Abstract

The invention comprises a dynamic compaction machine construction and operation parameter acquiring system and an operating method thereof. The dynamic compaction machine construction and operation parameter acquiring system is characterized in that: a programmable logic controller PLC is connected with a signal receiving device, an optical encoder, a tension sensor, a buzzer and a display, and the signal receiving device communicates with a signal transmitting device; the optical encoder is connected with a pulley above a pounder hammer hook, and the tension sensor is connected with a steel wire rope; and the signal transmitting device is arranged outside a dynamic compaction influence range and is leveled, and is aligned with a dynamic compaction machine. The dynamic compaction machine construction and operation parameter acquiring system and the operating method thereof have the beneficial effects that precise acquisition and dynamic real-time display of tamping settlement, accumulated tamping settlement, pounder hammer weight, falling distance and tamping energy data can be realized, the detection result cannot generate measurement errors due to the influence of factors such as sagging of the dynamic compaction machine.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a system for collecting parameters of dynamic compaction construction operations including ramming sinkage, accumulated ramming sinkage, falling distance, hammer weight, and ramming energy, and a working method thereof. Background technique [0002] The dynamic compaction method is to impact the soil body through the free fall of the heavy hammer, causing the pores of the soil body to compress and reduce its compressibility, thereby increasing the strength of the soil body. The dynamic compaction method is widely used in foundation and subgrade reinforcement due to its advantages such as remarkable reinforcement effect, simple equipment, convenient construction, wide application range, easy economy and material saving. [0003] There are many construction control parameters in the process of dynamic compaction construction. The current "Technical Specifications for...

Problems solved by technology

This process is not only cumbersome and labor-intensive, but also the reliability of the data is not high. In the case of lax supervision, there may be data fraud and other phenomena, which will lead to a decrease in construction quality and cause serious engineering quality problems.

Secondly, because the ground is relatively soft, the vibration and other factors will inevitably lead to the subsidence of the dynamic compaction machine during the tamping process. Therefore, the detection method of the tamping amount based on the dynamic compaction machine itself will not be accurate in the actual measurement process. A certain measurement error is generated, which is not allowed for the control of construction quality

However, none of the existing tamping detection methods can solve the above problems.
