Description

Protection device for measuring sign

Technical Field

The utility model relates to the field of constructional engineering, in particular to a protection device for a measuring sign.

Background

The measurement markers are generic names of the stone, target, and other markers used for measurement that demarcate the position of the ground measurement control point. Is a variety of signs that the mapping department establishes at the time of measurement and remains on the ground, underground, or building after the measurement. Each measuring sign is precisely measured and calculated to obtain the plane position and the altitude data of the measuring sign on the ground. In the existing measurement mark setting, a concrete cover plate which is engraved with specific point position information and is coated with paint is arranged at the top opening of a well after a measurement mark is arranged for protecting the well.

This prior art has drawbacks in use. The measuring mark is often located in the field environment, and the common concrete slab is easy to erode in use, so that the problems of concrete slab defect, surface handwriting corrosion, blurry and the like are caused.

In order to solve the problems in the prior art, the patent of the utility model with the authority bulletin number of CN202382737U discloses an adjustable measuring mark protection device, which comprises a steel pipe arranged outside a measuring mark, wherein the steel pipe is connected with a steel sleeve, and a steel cover plate is welded on the upper end surface of the steel sleeve. The device is arranged on the measuring sign, can avoid the damage of the measuring sign caused by the external interference, and is suitable for the protection of the measuring sign buried in the ground surface.
