Description

technical field [0001] The invention belongs to the field of concrete construction, and in particular relates to an integrated equipment for intelligent vibrating and plastering of concrete based on vibration wave signal control, which is suitable for efficient and accurate construction of continuous long-line cast-in-place planar structures such as ballastless track concrete bases and ballast beds. Background technique [0002] Vibration is an important link in the concrete construction process. Through low-amplitude and high-frequency vibration, energy is transferred to the concrete mixture, so that all particles within the vibration range are forced to vibrate. Vibration reduces the viscosity and internal friction of the concrete mixture within the effective range of the vibration, changes the fluidity of the slurry, the aggregate particles sink and slide under the action of gravity, and the large air bubbles float up and discharge under the action of buoyancy. Or be vibr...

Problems solved by technology

However, in the actual construction process, due to the large interference of human factors and extensive management, it is difficult to accurately control the concrete vibration work by relying on supervisors and construction personnel to manually control the vibration, resulting in leakage, under-vibration, and vibration during construction. Over-vibration and other problems, the construction quality cannot be guaranteed, and the construction efficiency is difficult to improve

[0003] Concrete vibrated compactness can be evaluated by parameters such as density, strength, and pore structure after hardening, but an evaluation method similar to "post-feedback" is very unfavorable for actual engineering quality control. remedial measures to resolve

In the actual pouring process, there is no uniformly determined index for evaluating the compactness of concrete vibrating. The quality control of vibrating construction depends on human experience, which can only be roughly estimated and cannot be finely controlled.

Measuring and comparing the performance parameters of the fresh mix before and after vibration can evaluate the concrete compactness in real time, but the equipment structure is often complicated and the operation is difficult, so it is not suitable for on-site construction

[0004] The research on vibrating automation and intelligent construction is gradually increasing. The patent "An Automatic Vibrating Equipment" uses automatic vibrating equipment to replace manual work, which greatly reduces the labor burden of workers, realizes human-computer interaction, and improves vibrating efficiency. However, it is difficult to disassemble and move the equipment, so it is not suitable for long-term cast-in-place structures

The patent "A CRTSⅢ Ballastless Track Base Plate Concrete Automatic Forming Machine" can accurately plaster and lift the CRTS Ⅲ ballastless track base plate, but it does not have the vibration function, and the structure is complicated, so it can only be used in specific structures

"A Smart Vibrator for Cast-in-place Ballastless Track of High-speed Railway" realizes on-site pouring and automatic vibration of high-speed rail track slabs by pre-setting the vibration time, insertion depth and vibration interval, but it cannot intelligently judge the degree of concrete density in real time

In addition, for example, GPS devices are used to test parameters such as the position, depth, and angle of the vibrating rod, and image simulation analysis software and devices are used to monitor the vibrating construction. New technologies have begun to be applied in vibrating construction. These studies can intelligently determine Construction status and planned construction route, but construction still relies heavily on manpower, it is impossible to determine the compactness of concrete vibration in real time, and it is impossible to realize precise and unmanned intelligent vibration construction of concrete

After vibrating, it is necessary to carry out a second finishing process on the surface. At present, the surface plastering construction relies heavily on manpower, the construction progress is slow, and the process connection time is long
