Excavation Construction Auxiliary Device

Abstract

The invention discloses an auxiliary device for excavating construction. The auxiliary device for excavating construction comprises a main body, a reflecting part, wire reels, a first light beam transmitter and second light beam transmitters, wherein the first light beam transmitter is used for displaying excavating depth, the second light beam transmitters are used for displaying plane elevation, the reflecting part, the wire reels, the first light beam transmitter and the second light beam transmitters are fixed on the main body, and a light ray direction of the first light beam transmitter is vertical to that of every second light beam transmitter. The auxiliary device for excavating construction has the advantages that the reflecting part erected on a measurement main body of a total station instrument or a half-station instrument on an excavating construction site is used for calibrating accuracy of a mounting position of the auxiliary device for excavating construction; when the auxiliary device is operated in the daytime, a wire of every wire reel is pulled out horizontally to display the plane elevation and is pulled to a measurement position so as to obtain the excavating depth by means of measurement; when the auxiliary device is operated at night, the first light beam transmitter is arranged vertically and turned on to irradiate a marked position and therefore can reflect whether the excavating depth meets the requirements or not visually, and the second light beam transmitters are arranged horizontally and turned on to display the plane elevation.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an auxiliary device for excavation construction. Background technique [0002] Urban power grid is an important infrastructure of the city. With the rapid development of cities in our country, power tunnels have become the main way of laying urban power grids. Power tunnels have the advantages of not occupying land resources on the ground, high safety and reliability, and simple and convenient maintenance. Through the comprehensive planning of the power tunnel layout, the resources of the power tunnel are further optimized, the utilization rate of the power tunnel is improved, the cable entry and exit of the power station are convenient, the cable path is shortened, and the power operation environment is improved. At the same time, the overhead cables in urban areas have been comprehensively transformed to pass through the ground, improving the urban landscape, and...

AI Technical Summary

Problems solved by technology

Due to the small excavation area of ​​the working shaft of the power tunnel and the 24-hour uninterrupted construction, there is a safety risk of cross-construction and the interference of external factors at night leads to setting-out errors

Therefore, during the process of measurement, lofting and positioning, the excavation must be stopped, and the next process can only be carried out after the measurement, lofting and review work is completed. The construction period is affected, the efficiency is reduced, and the manpower and material resources are greatly invested
