Problems solved by technology
In practical operation, when workers plug and unplug the mobile vibrating rod, they cannot accurately grasp the position, range, depth and duration of vibrating. It is often an empirical operation, which is highly random and difficult to quantify the effect, especially the insertion depth and duration. Whether the vibration time meets the process requirements is the key to defects such as under-vibration, over-vibration or leakage
At present, there is no reliable technical solution at home and abroad. Therefore, it is necessary to use sophisticated and intelligent vibrating operation process judging equipment and technical means to effectively monitor the quality of concrete vibrating

The invention discloses a real-time and intelligent judgment device and method for the valid vibration depth and state of concrete. The device comprises a collection device, a positioning module and a vibration state collection device, wherein the collection device is arranged on site and collects the distance between an operation handheld stick part and a stick head. The collection device for collecting the distance between the operation handheld stick part and the stick head comprises a Hall sensor set, a magnetic working glove and an intelligent module. The Hall sensor set is arranged on a vibration stick body. The magnetic working glove is worn by an operator. The Hall sensor set is connected with the intelligent module. The positioning module comprises two GPS positioning antennas arranged on the two shoulders of the operator. The vibration state collection device judges the vibration stick working state through a non-contact type vibration time intelligent detection system and method (the patent number 2014104379939). The intelligent vibration depth and state judgment process can be achieved, and the process of obtaining vibration point positions is high in data precision, stable and reliable.
Description
technical field [0001] The invention relates to a device and method for intelligently determining the effective vibration depth and state of concrete in real time, and belongs to the field of concrete pouring quality control. Background technique [0002] In concrete construction, vibration is the key to the quality of concrete buildings. Reliable testing and evaluation of the vibration depth and continuous vibration time of fresh concrete pouring is one of the important links in quality control. [0003] At present, the vibrating method used on the construction site is based on the effective radius of the vibrating rods of different rod types, and it is required to insert the vibrating rods in a staggered manner to ensure that the concrete pouring area is basically vibrated and compacted. The vibrating regulations in the construction specification are relatively vague, and the standard is based on the basic bleed and no sinking. In practical operation, when workers plug an...
