[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is an invention relating to an improvement of a staff used for road construction work for newly passing a road and a staff support for erecting the staff.

[0002]

[Prior Art]

 17 and 18 are vertical cross-sectional views showing the state of road construction work. When newly constructing a road to pass through a road, first install a water thread tensioning tool to a width according to the design dimensions. After installing and tensioning the water thread 9 between the tensioning tools 10 and 10, digging a groove 12 having a predetermined width and a predetermined depth in the ground surface 11 to a predetermined width and depth necessary for road construction work. When the excavated trench 12 is completed, it is required to work within the strict standard range to eliminate the error between the design dimension and the finished dimension of road construction. It is also obliged to take a record-keeping photo that shows the progress of road construction work in order to confirm whether the road construction work conforms to the standard. These strict requirements are also demanded on the thickness of the crushed stone laid in the groove 12. For example, in the design of the thickness of the crushed stone 14 laid in the trench 12 dug by road construction work, the measurement frequency is set to -50 mm and the measurement frequency is set to 1 point for every 20 m of extension and 5 points for 1 point. In such a case, the person who constructs the road construction work manages the construction based on this design and submits the management result to the orderer. However, like the crushed stone 14, the thickness of the crushed stone 14 after the road construction work is completed. Since it is no longer possible to check, it is necessary to take a picture of the management situation and keep it as a record. Therefore, if there are 5 points in one place, as shown in FIG. Five people and one person who will take recorded photographs and six persons in total will be required, and if the length of road construction work is 300 m, it will be taken at 16 places. 1 work for each layer Since performed six times from 3 times to a large number of manpower required, labor costs increase. In addition, in this way, many people are not on the water line 9, the staff 2 and the road surface for the purpose of taking a picture, which may cause obscurity in the picture taking. Regarding the measurement, as shown in FIG. 13, after putting the crushed stones 14 into the groove 12 and flattening the surface 13 of the crushed stones, 16 or more persons holding the staff 2 again with one hand on the crushed stones surface 2 2.2.2 Stand up vertically and measure whether the thickness of the crushed stone 14 is in conformity with the planning criteria using a surveying instrument. That is, the difference obtained by subtracting the distance L2 from the crushed stone surface 13 to the water thread 9 from the distance L1 from the groove bottom surface 15 to the water thread 9 becomes the thickness L3 of the crushed stone 14 laid in the groove, and the formula is L1-L2 = It is represented by L3.

[0003] According to the method described above, it is impossible to save an accurate record photo because the record photo of the depth of the groove and the thickness of the crushed stone is measured with a large number of hands, so that the labor cost is reduced. However, there is a drawback that the work efficiency is extremely poor because the road construction work cannot be carried out quickly and effectively.

[0004]

[Problems to be solved by the device]

 The present invention, when recording and photographing the management results such as the thickness of the crushed stones 13 in the groove 12 for road construction work by a photograph, surely and clearly by raising the staff on this support, Compared to the large number of manpower required, by using the staff for supporting the staff of the present invention, it was devised in order to record and photograph with extremely few manpower.

[0005]

[Means for Solving the Problems]

 According to another aspect of the present invention, there is provided a staff member for mounting a plurality of legs on a lower end of the pillar and a supporting portion for mounting a staff on the pillar, and an upper portion of the pillar is bent at a right angle to the pillar.
