AI Technical Summary

Technical Problem

Conventional automated green cutting devices require cumbersome manual input of planned driving routes and adjustments for varying concrete surface conditions, leading to inefficiencies and quality issues in construction joints due to time differences in concrete hardening across a work area.

Method used

A green cutting device equipped with a time information input means, area defining means, mapping means, self-position estimation means, and driving control means, which automatically adjusts its travel path based on elapsed time and weather information to ensure timely and uniform removal of laitance layers.

Benefits of technology

Simplifies automatic travel control and improves the quality of construction joints by ensuring green cutting operations are performed at the appropriate timing, reducing manual input and accounting for varying concrete conditions.

Abstract

To simplify the automatic running control of a green cutting device and to improve the quality of seams by performing green cutting work at appropriate timing.SOLUTION: A green cutting device 10 includes: a device main body 11 having a travelling unit 12; time information input means for inputting time information when the compaction work of concrete 3 is completed; area defining means for defining the range of a work prohibited area 2a in which work by the device main body 11 within a work area 2 is prohibited to be reduced in accordance with the elapsed time from the time information input by the time information input means; mapping means for creating map information of the range traveled by the device main body 11; self-position estimating means for estimating the position of the device main body 11; and travel control means that drives and controls the traveling unit 12 based on the positional relation between an area 2b excluding the work prohibited area 2a and the device main body 11 in the work area 2.SELECTED DRAWING: Figure 1
