Abstract

(57) [Abstract] [Problem] The present invention improves the construction ability by switching the roadbed position and thickness management, which depend on actual measurement in road pavement work, to a safe and fast operator's visual inspection. It is characterized by displaying the roadbed line indicating the roadbed position of the roadbed designated by the owner, which is a quick, cheap, and good-quality paved road construction and serves as a guide for visual observation to enable switching. It concerns a gutter. According to the present invention, in road pavement construction, prior to roadbed construction, the owner designates on the side wall 3 of the gutter which is buried by aligning the upper surface 2 of the gutter horizontally at the position of the road surface indicated by the owner. The position of the roadbed from the road surface is indexed from the upper surface 2 of the gutter which is horizontal to the road surface, and the roadbed line that is the target of visual measurement is displayed at that position. Made possible to build a roadbed based on.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention replaces dangerous and time-consuming, time-consuming, actual measurement-dependent roadbed construction with operator's visual inspection, which is dangerous and time-consuming, to interrupt the operation of power shovels at hand during road paving work. In order to improve the road capacity and the construction capacity, the roadbed line of the present invention showing the roadbed position of the roadbed designated by the owner, which enables the switching, is embedded in the roadway structure in advance. The present invention relates to a gutter displayed on the side wall.

[0002]

[Prior art]

 In the road pavement work designated by the owner, excavation, leveling, pavement material input, leveling, rolling compaction, road layer position, thickness, etc. are all managed by skilled operators. Then, it was a construction method that interrupted the operation of the power shovel, was dangerous for the personnel at hand, took time, and relied on actual measurement.

[0003]

[Problems to be solved by the device]

 The present invention replaces the above-mentioned faulty construction method, which depends on actual measurement, with a construction method that depends on the operator's eye side, which is safe and excels in speed, in order to improve safety and construction ability. The roadbed line according to the present invention, which indicates the roadbed position of the roadbed designated by the owner and serves as a guideline on the operator's eye side that enables the switching, is embedded before the roadbed is made. The purpose of the present invention is to provide a gutter that is characterized by being displayed on the side wall of the gutter, to enable the construction of a paved road that is safe, fast, cheap, and has a high finishing accuracy, and to solve the above-mentioned drawbacks.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a method for burying a gutter 1 in which the upper surface 2 of the gutter 1 is horizontally aligned and buried at the height of the road surface instructed by the owner prior to roadbed construction in road repair work. On the side wall 3, the position 4, 5, 6 of the roadbed from the road surface designated by the owner is indexed from the upper surface 2 of the gutter 1 which is horizontal to the road surface, and at that position, the accurate eye side, which is the basis of the present invention, is located. The roadbed lines 7, 8 and 9 that indicate the roadbed position, which serves as a guideline, were marked to enable the construction of the roadbed depending on the eye side, which was a means of solving the problem.

[0005]

[Embodiment of device]

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings with reference to the drawings. The drawings show an embodiment of a three-layer paved roadbed according to the present invention, in which 1 is a gutter previously buried in a road pavement work, and 2 is an owner's instruction. The upper surface of the gutter 1 that is horizontal to the position of the road surface, 3 is the side wall of the gutter 1 that indicates the roadbed lines 7, 8 and 9 that serve as a guide for visual measurement, 4 is the lower roadbed of the crushed crushed stone, and 5 is the grain crushed stone Upper layer roadbed, 6 is a surface layer roadbed of dense grain ascon, solid lines 7, 8 and 9 are the roads of the roadbeds 4, 5 and 6 designated by the owner, which are indexed from the upper surface 2 of the gutter 1, which is horizontal to the road surface designated by the owner. The roadbed line according to the present invention showing the floor, 7 is the roadbed of the lower roadbed, 8 is the roadbed of the upper roadbed, 9 is the roadbed of the surface roadbed, and the roadbed line is limited to the solid line shown in the embodiment Do not use broken lines and chain lines with different colors.The thickness of the subgrade line should be within the tolerance of the subgrade position unless specified by the owner. The number of subgrade lines match the number of subgrade designated by the Buyer, subgrade line is also a line indicating the ceiling of the lower path layers.

[0006]

[Effect of device]

 According to the present invention, as described above, since the roadbed line according to the present invention indicating the position of the roadbed designated by the owner is marked on the side wall of the gutter, it is possible to make the roadbed depending on the eye side. Produce an effect.

[0007] It is possible to eliminate the dangerous and time-consuming work of the personnel at hand, to reduce the work on the actual side, improve the safety of the personnel at hand, and save labor.

[0008] The operation of the power shovel is interrupted, the actual work is reduced, and the construction capacity is improved.

Roadbed construction is facilitated by using the roadbed line as a guide, no skilled operator is required, and it is easy to secure an operator.

Inspection and supervision can be performed at any time by using the roadbed line as a guideline, and construction management becomes easy.
