The surveying nail 50 driven into the nail hole is fixed to the ground of concrete or asphalt by striking it. Are formed.

The number plate 53 is used for numbering the measurement points, and is made of a disc-shaped aluminum plate having a hole formed in the center thereof into which the survey nail 51 is driven. Of three or four digits (e.g., "521") indicating the serial number, and two digits (e.g., "04") or a number of "A" to "Z" indicating the block number of the measurement point. The letters of the alphabet are printed, and letters such as “land survey” are printed according to the order.

[0005]

[Problems to be solved by the invention]

 The surveying point display panel 52 and the license plate 53 are arranged side by side as shown in the figure, and each is nailed to the ground with individual surveying nails 50 and 51, so that the nailing work is troublesome. In addition, drilling was required in advance on hard ground such as concrete roads, which required a lot of time and labor for nailing work.

In addition, at least two types of survey nails 50 and 51, large and small, must be properly used for the point display panel 52 and the license plate 53. In addition, each of the survey nails 50 and 51 is used for concrete roads. It is necessary to prepare various sizes, such as short and small sizes, long and small sizes for gravel roads, and intermediate sizes for asphalt roads, and use them as appropriate according to differences in road surface conditions. And the number was large, and it was troublesome to use them properly.

[0007] In the license plate 53 installed on the road surface, the numbers, letters, and the like printed on the surface of the license plate 53 are easily lost due to abrasion caused by traffic of vehicles and people, and fading due to ultraviolet rays of sunlight. However, there is a problem that the service life is short.

Accordingly, the present invention reduces the type and number of surveying nails used when installing a survey display panel and a license plate to greatly reduce nailing labor, and at the same time, prints on the license plate. The technical task is to prevent the loss of the numbers and letters and improve the useful life of the numbers.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a new survey sign that uses a station display panel for marking station points and a license plate for numbering stations in an integrated combination. The surveying marker has a recess formed on the upper surface side of the survey point display panel for horizontally fitting a license plate, and a nail hole for driving a survey nail for fixing the survey point display panel at the center of the recess. It is characterized in that a nail hole is formed at the center of the license plate and has a hole diameter such that a survey nail for fixing the measuring point display panel can be driven.

In the surveying sign of the present invention, a number plate is fitted into a concave portion formed on the upper surface side of a point display panel, and a center of the concave portion of the point display panel is inserted through a nail hole formed at the center of the number plate. Driving a survey nail into the ground through the nail hole formed on the ground, and fix the station display panel and the license plate integrally on the ground.
