Embodiment Construction

[0027] The specific implementation is as follows:

[0028] 1. Prefabricate the round convex prefabricated parts according to the following process

[0029] 1. Processing tire mold and flat steel ring

[0030] see figure 1 , using cast steel tire mold 1, according to the size and shape of the diameter of each circular protrusion, the surface of the tire mold 1 is set to be a conical concave surface, and each "U" type anti-skid groove 2 is set in concentric circles on the conical concave surface, flat The steel ring 3 stands upright on the outer circumference of the tire mold 1, and on the outer circumference of the tire mold 1, a thread opening is arranged, and each steel gasket 4 and the outer round nut 5 pairs of flat steel rings arranged on the outer circumference of the tire mold 1 3 Position the entire circle, adjust the slight deformation of the flat steel ring 3 due to external force or local high temperature generated during welding, so that the outer wall of the flat...

Abstract

The invention discloses a pavement construction method with big and small bosses. The method is characterized in that the boss fabricated parts are firstly produced in advance, then the boss fabricated parts are installed and the pavement concrete is poured. The method of the invention is simple and the pavement quality is reliable.

Description

technical field [0001] The invention relates to a construction method of concrete pavement, more specifically a construction method of concrete pavement applied in special occasions. Background technique [0002] Large and small round convex roads are the requirements for the road surface in some special occasions. For example, in the China FAW Nong'an Automobile Proving Ground, the large and small circular convex roads are located at K0+340~K0+510 and K2+800~K2+ of the durability test. Section 920, the pavement structure is cement concrete, the large round convex road is 170m long, the road surface width is 6.50m, the small round convex road is 120m long, and the road surface width is 6.50m. This kind of road surface is mainly for the test of cars passing through obstacles, and the distribution of large and small circle bumps is irregular. [0003] But, so far, there is no public report about the large and small round raised pavement construction methods. Contents of the...
