Embodiment Construction

[0016] Take, for example, vibratory rollers whose vibration frequency and operating amplitude can be adjusted electronically.

[0017] The vibration wave when the road roller is working is continuously transmitted into the soil and propagates to the surroundings. Due to the effect of geometric damping and viscous damping, its amplitude will attenuate with the increase of distance.

[0018] The propagation and attenuation of vibration waves are mainly related to the characteristics of the vibration source (the working amplitude and vibration frequency of the vibratory roller, etc.), the medium conditions (the vibration attenuation characteristics of the soil), and the distance from the vibration source.

[0019] The impact of construction vibration on buildings is mainly based on the maximum vibration velocity, maximum vibration acceleration, maximum amplitude, and spectral intensity as evaluation indicators. In this embodiment, the maximum vibration acceleration is used as the ...

Abstract

A road roller early warning device for preventing building damage relates to an early warning device for preventing surrounding building damage caused by road roller vibration. The road roller early warning device mainly comprises a rotating speed sensor, a distance sensor, a manual parameter inputting device, a working amplitude signal inputting device, a microprocessor, an alarming indicating device, a signal processing device, and the like, wherein the rotating speed sensor measures the vibration frequency of the road roller; the distance sensor measures the distance between a road roller and a building; the manual parameter inputting device is used for manually inputting vibration attenuation characteristic parameters of soil; the working amplitude signal inputting device is used for inputting the working amplitude signal of the road roller; and the microprocessor analyzes influences of the vibration of the road roller on the building according to the collected parameters and allows the alarming indicating device to give an alarm to an operator of the road roller in time. The road roller early warning device can achieve damage protection for the building, avoids worries of the operator about the influences on the building, improves work quality and increases the work efficiency.

Description

technical field [0001] The invention relates to a road roller early warning device, in particular to a road roller early warning device for preventing damage to surrounding buildings caused by the vibration of the road roller. Background technique [0002] The road roller is a kind of construction machine whose main purpose is to increase the density of the working medium. It is widely used in the construction of road engineering, hydropower engineering, port airport, and municipal engineering. [0003] In new road construction and old road renovation projects, in order to improve the strength of the roadbed and pavement and ensure the quality of the road surface, it is necessary to use a road roller to compact the roadbed and pavement. When the road roller is working, vibration waves are continuously transmitted into the soil and spread around to cause peripheral vibration. However, in the road construction near residential areas and buildings, the strong vibration waves o...
