High-stability anti-collapse cement pavement construction method

Abstract

The invention discloses a high-stability anti-collapse cement pavement construction method, and belongs to the field of pavement construction.The high-stability anti-collapse cement pavement construction method comprises the following steps that embedded wire balls are added into a concrete layer, under the attraction action of a ball guide magnetic plate, collision thorn balls continuously collide with a fragile wire board, on one hand, surrounding concrete slurry is driven to achieve a certain vibration effect, the small void volume is reduced, the strength of the pavement is remarkably improved, and the collapse probability of the pavement is reduced; and on the other hand, when the collision thorn balls collide with the fragile wire board, the fragile wire board is gradually broken, the outer protective shell is crushed, at the moment, a joint mixture in the outer protective shell overflows, smaller gaps are further filled, meanwhile, flexible drawing wires can be gradually embedded into the whole concrete slurry, so that the connection degree of an integrally formed concrete layer is remarkably improved, the strength and the bearing performance of the road surface extruded byheavy vehicles are effectively improved, and the occurrence efficiency of cracks or collapses is reduced.

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...

AI Technical Summary

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
