Embodiment Construction

[0018] like figure 1 , figure 2 As shown, the structure of the present invention includes a cylindrical post body 1 and an elastic steel belt 2 plugged in the center of the post body. The post body 1 has a diameter of 50 mm and a height of 120 mm, which can be formed by condensation of various building materials. , the shear strength is within the range of shear strength that can be scraped off by the leveling machine, and the compressive strength is not lower than the strength of the surrounding foundation. The elevation control line 3 of the roadbed construction is set at a height of 100mm from the main body of the pillar. The marking column body 1 is divided into an upper monochrome column section 4 and a lower monochrome column section 5; the elevation control line is located on the upper monochrome column section, and the upper end of the elevation control line 3 up to the upper monochrome column section 4 is the specified subgrade construction. The height of the deviat...

Abstract

The invention relates to a guard post for roadbed construction and a roadbed construction method. The structure of the guard post for the roadbed construction comprises a cylindrical guard post body and an elastic steel strip which is inserted at the center of the guard post body; the shear strength of the guard post is within the shear strength range within which the guard post body can be scraped by a scraping machine; the height of the guard post body is not less than 120 mm; the elevation control line of the roadbed construction is set at a height of at least 100 mm on the guard post body; the guard post body comprises an upper monochromatic column section and a lower monochromatic column section; the bottom end of the elastic steel strip is fixed at the center of the lower monochromatic column section; and the top end of the elastic steel strip is higher than the top surface of the guard post body. The guard post for the roadbed construction has the advantages of obvious marking effect, convenient use, simple and convenient making and so on.

Description

technical field [0001] The invention relates to a roadbed construction marking tool and a roadbed construction method, in particular to a roadbed construction marking post and a roadbed construction method. Background technique [0002] During the construction of the subgrade of the road square, elevation control is an important factor related to the construction quality. The elevation thickness of lime soil at each step requires elevation control. If the thickness of lime soil is inconsistent, it will lead to inconsistent compaction of this layer of soil, which will not only affect the construction of subsequent processes, but also affect the construction quality. If the gray soil elevation exceeds the error range, it will inevitably lead to rework and reconstruction of the project. Therefore, elevation control is a tedious and important task for construction and road construction enterprises. [0003] The patent document (ZL201320767770.X) discloses a kind of white gray...
