A construction method for high-stability anti-collapse cement pavement

Abstract

The invention discloses a construction method for a high-stability anti-collapse cement pavement, which belongs to the field of pavement construction. It relates to a construction method for a high-stability anti-collapse cement pavement. The attraction effect of the slab, the collision thorn ball continuously collides with the brittle line slab, on the one hand, it drives the surrounding concrete slurry to play a certain vibration effect, reduces the small void volume, and then significantly improves the strength of the pavement and reduces its collapse. On the other hand, when the brittle wire board collides with the brittle wire board, the brittle wire board is gradually broken and the outer shell is crushed. At this time, the caulking agent inside it overflows to further fill the smaller gaps. Gradually embedded in the entire concrete slurry, it can significantly improve the connection degree of the overall formed concrete layer, effectively improve the strength and bearing capacity of the pavement when it is squeezed by heavy vehicles, and reduce the occurrence efficiency of cracks or collapses.

Description

technical field [0001] The invention relates to the field of pavement construction, in particular to a construction method for a high-stability anti-collapse cement pavement. Background technique [0002] Cement concrete pavement refers to the pavement with cement concrete as the main material, referred to as concrete pavement. Also known as rigid pavement, commonly known as white pavement, it is a high-grade pavement. Cement concrete pavements include plain concrete, reinforced concrete, continuously reinforced concrete, prestressed concrete and other pavements. The materials used for cement concrete surface include ordinary concrete, reinforced concrete, continuous reinforced concrete, steel fiber concrete, roller compacted concrete, etc. [0003] To prepare concrete for pavement, soft-fired No. 425 or No. 525 ordinary Portland cement, medium sand or coarse sand, and Class I and II crushed (gravel) stones should be used. The 28-day ultimate compressive strength of concr...

Problems solved by technology

[0006] When the cement pavement is poured, although the internal voids are reduced by the vibrating rod, there are still a certain number of small voids, so that the connection strength between the formed concrete layers is not high, resulting in the existing cement pavement being used for several years. After that, the pavement usually cracks or even collapses, so that the overall service life of the pavement is not long, and higher maintenance costs need to be added later
