DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a work management device for tunnel construction, and in particular, to automatically calculate the actual working time of tunnel construction, which is constructed in a series of work procedures, along with the work progress state. The present invention relates to a management device that can display information.

(Background of the Invention) A blasting method using explosives is known as a method of excavating rock to construct tunnels and the like.

This type of blasting method usually involves a drilling process in the face, a charge detonation process in which an explosive is attached to the hole and the explosive is detonated, a shearing process, a primary spraying process, a rock bolt installation process, and a second process.
The next spraying process is followed by the water stop process, and the tunnel is constructed by repeating this process.

By the way, when constructing crude oil storage tanks in bedrock, a large number of faces may be constructed at the same construction site, such as for excavating rock tanks and connecting tunnels between tanks.

Under such construction conditions, work management for each face has traditionally been carried out by selecting a manager for each construction process mentioned above, and having the selected manager report work hours and other information to the site office through daily reports. Ta.

However, with such work management methods, daily reports are only submitted the day after the work is completed, making it impossible to obtain information in real time, and it is difficult to obtain an overall understanding of the progress status of work at multiple faces. There was also the problem that it took a long time to compile the data.

This invention was made in view of these conventional problems, and its purpose is to provide a system for tunnel construction in which work information can be grasped in real time and the work at a large number of faces can be easily aggregated. The purpose of the present invention is to provide a work management device.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a face drilling process, a charge blasting process in which explosives are attached to the hole and detonated, a shearing process, a primary spraying process, Rock bolt installation process, 2

A work start signal and a blaster operation signal for the charge blasting process, an operation signal for a loading machine that loads waste onto an earth and sand transport vehicle in the scrap removal process, and an entrance/exit signal for an earth and sand transport vehicle for transporting the waste; The first spraying is based on the operation signal of the spraying machine in the process,
A driving signal for a nut tightening machine in the lock bolt installation process, an operating signal for a spraying machine in the secondary spraying process, and a driving signal for a nailing machine in the water stopping process are input signals, respectively, and these input signals are used as input signals. The present invention is characterized by comprising an arithmetic device that tabulates the working time of each of the steps in the order of the steps based on the signal.

(Operation and Effect of the Invention) According to the work management device for tunnel construction having the above configuration, electric signals corresponding to the start and end of the work are output in each process from drilling to water stoppage, so the work status in each process is can be understood in real time.

Furthermore, since the signals output from each process are automatically processed by the arithmetic unit and tabulated in the order of the processes, even if there are a large number of faces, it can be easily handled and tabulation becomes easy.
