Construction method for road base concrete side mold

Abstract

The invention provides a construction method for road base concrete side molds. Construction steps are as follows: 1) laying of a sub-layer; 2) measuring and arranging of sidelines of vertical curbstones; 3) installation of templates; 4) pouring of concrete side molds; 5) laying of a lower base of lime-fly ash stabilized aggregate, an upper base of lime-fly ash stabilized aggregate and a cement stabilized crushed rock layer; 6) laying of vertical curbstone concrete foundation; 7) installation of vertical curbstones on the vertical curbstone concrete foundation; 8) pouring of vertical curbstone reinforced concrete at external sides of vertical curbstones; 9) laying of an asphalt sealing layer, a coarse-grained asphalt layer, a medium-grained asphalt layer and a fine-grained asphalt pavement layer at internal sides of vertical curbstones. When the road base concrete side molds are poured, the sidelines are arranged accurately, a straight degree and top elevation of the road base concrete side molds are strictly controlled, and paving width and thickness of the road bases are effectively controlled. The concrete side molds are used as an elevation control reference surface for pavingof the road bases and installation of vertical curbstones, which enables flatness of the road bases, straightness of the vertical curbstones and a qualified rate of top elevation to be greatly improved.

Description

technical field [0001] The invention relates to the technical field, in particular to a road base concrete side form construction method. Background technique [0002] At present, steel formwork or wooden formwork is generally used for the paving of the road base of municipal engineering according to the traditional construction technology, and soil formwork is also used if there is soil source on site. Steel molds and wooden molds have sufficient strength and rigidity, and are easy to disassemble and assemble, but they are not suitable for support and reinforcement. The advantage of the soil model method is that the materials are obtained locally, the construction is simple and fast, but its strength is insufficient, it is easy to loosen, and it is not easy to use in the rainy season, and it is greatly affected by the season. The above several side formwork construction techniques require multiple measurements of alignment and elevation, resulting in large cumulative error...

Problems solved by technology

[0008] The above two construction techniques require multiple measurements of alignment and elevation, resulting in large cumulative errors and inaccurate elevation control

When the mixture of the road base is rolled, it will be pushed laterally, resulting in a lower elevation of the edge and a larger cross slope, and the compactness of both sides of the road base cannot be guaranteed.
