Problems solved by technology

Due to the large fluidity of the mortar, the enclosure effect is not ideal, and the adjacent road surface is easily polluted. If the brush stays in the grouting area for a short time, it will not be able to form a certain liquid level, resulting in insufficient grout perfusion, which will affect the infusion composite The appearance and construction quality of the pavement; if the edge sealing method is used to seal the edge with a foaming agent, there will be grout leakage caused by the uneven spraying of the foaming agent, and it is not beautiful

Embodiment 1

[0023] The average flatness of the adjacent asphalt pavement 3 is 3.2mm before construction of the poured composite pavement, and the flatness of the pavement is relatively good. During the cooling process after the asphalt mixture with large pores is paved, before the grouting construction, use a forest fire blower and a broom to clean up the asphalt pavement 3 or curbstone 2 adjacent to the grouting area 1, and then in the grouting area 1 Two rows of edge banding strips with a certain height and weight are placed in parallel on both sides along the length direction of the grouting area. The width of a single edge banding strip 5 is 5cm, the height is 5cm, and the length is 400cm. The material is rubber. Construction conditions Tightly splice the edge banding strips 5 section by section along the length direction of the grouting area. The gaps between the strips 5 are filled, and the edge strips 5 are removed after the mortar is formed. The filling material 4 is early-streng...

Embodiment 2

[0025] The average flatness of the adjacent asphalt pavement 3 is 6.4mm before the construction of the poured composite pavement, and the flatness of the road surface is poor. During the cooling process after the asphalt mixture with large pores is paved, before the grouting construction, use a forest fire blower and a broom to clean up the asphalt pavement 3 or curbstone 2 adjacent to the grouting area 1, and then in the grouting area 1. Two rows of edge banding strips 5 with a certain height and weight are placed in parallel on both sides along the length direction of the grouting area. The width of a single edge banding strip 5 is 5 cm, the height is 8 cm, and the length is 600 cm. The material is rubber. The specific construction conditions are to closely splice the edge strips 5 one by one along the length direction of the grouting area. The gap between the two rows of edge strips 5 is controlled between 1cm and 3cm. The gap between the edge strips 5 is filled, and the ed...

Abstract

The invention discloses an edge sealing method for injected compound pavement grouting construction. The method includes the steps: cleaning the periphery of a grouting area after matrix asphalt mixedmaterials are constructed; parallelly placing two rows of edge sealing strips on two sides of the grouting area along the length direction of the grouting area, and reserving a certain gaps between the edge sealing strips; fully filling the gaps between the edge sealing strips with rapid curing filling materials; disassembling the edge sealing strips after the filling materials are harden to formstrength. The edge sealing method combines the edge sealing strips with the filling materials, brushes can be parallelly pushed and squeezed in starching construction after an injected compound pavement is grouted, slurry has a certain liquid level height in the grouting area, the pavement is fully grouted, appearance and construction quality of the pavement is improved, the edge sealing method adapt to be used on a rough pavement, peripheral flow of the slurry can be avoided, so that adjacent pavements cannot be polluted, slurry sealing effects are good, construction is simple, the edge sealing strips can be repeatedly used, and construction cost is reduced.

Description

technical field [0001] The invention relates to an edge sealing method for grouting construction of poured composite pavement, which belongs to the technical field of road construction. Background technique [0002] Pour-in composite pavement is a pavement that combines rigidity and flexibility by pouring cement-based grouting materials into the large-pore asphalt mixture matrix. It has the flexibility of asphalt pavement, good crack resistance, and no joints. And it has the characteristics of high rigidity, large bearing capacity and good anti-rutting performance of concrete pavement. [0003] Cement-based grouting is a very important step in the construction of poured composite pavement, which directly affects the appearance and construction quality of the pavement. Most of the cement-based mortar used is black and gray. If the edge sealing measures are not taken during construction, the adjacent road surface will be polluted by cement slurry, especially on the road with ...
