Background
The grouting composite pavement is a novel pavement with good rigidity and flexibility and good anti-rutting performance formed by pouring cement-based grouting materials into a macroporous asphalt mixture matrix. The pouring of the cement-based grouting material is a very important step in the construction of grouting composite pavements, which directly affects the pavement appearance and construction quality, the cement-based grouting material used in the construction of the grouting composite pavements is black or gray, if precautionary measures are not made during grouting construction, greening between adjacent pavements and roadside can be polluted by the cement-based grouting material, the grouting area has a problem of being raised relative to the original pavement or the edge of the grouting area has no kerbstone, kerbstone and the like to block the construction, and the edge sealing is also carried out by adopting a traditional method: the periphery of a grouting area is subjected to edge sealing treatment or is only horizontally covered with a film, then a large amount of manpower is adopted to continuously enclose and block mortar by brushes on two sides of a road, and because the mortar has good fluidity, the enclosing and blocking effect is not ideal, and adjacent asphalt pavements cannot be prevented from being polluted, so that the appearance and the construction quality of the semi-flexible pavement are influenced.
Disclosure of Invention
The problem that the regional original road surface of grout raised relatively of grout region to compound road surface stops the constitution with regional limit portion of grout does not have curb, curb etc. and leads to the grout in-process, and the slurry flows from the regional limit portion of grout, pollutes adjacent bituminous paving problem, the utility model provides a half flexible compound road surface construction banding structure of grout formula, this structure encapsulation is effectual, and maneuverability is strong.
In order to achieve the purpose, the utility model discloses a realize through following technical scheme:
the utility model relates to a novel compound road surface construction banding structure of grout, including flexible road surface grout blanket, lay waterproof roll material layer in the side portion of flexible road surface grout blanket, the part on waterproof roll material layer is pressed in the lower part of flexible road surface grout blanket, another part on waterproof roll material layer is in the side portion of flexible road surface grout blanket, set up first foaming layer and the second foaming layer of caulking in the outside on waterproof roll material layer, through the fixed waterproof roll material layer of first foaming layer and the second foaming layer of caulking, the outside on first foaming layer of caulking is road surface limit portion, the outside on second foaming layer of caulking is adjacent road surface.
The utility model discloses a further improvement lies in: the thickness of the waterproof roll material layer is more than 5cm larger than that of the flexible pavement grouting layer.
The utility model discloses a further improvement lies in: the length of the waterproof roll material layer pressed on the lower part of the flexible pavement grouting layer is 10-20 cm.
The utility model has the advantages that: the utility model discloses a combined edge sealing structure of waterproof coiled material layer and earth and stock form foaming joint filling layer, under the prerequisite that different structural layers, grouting area differ from the height of former road surface, other pitch road surface smoothness of the regional limit portion of grout is not good, can effectively exert the effect of stopping the excessive slurry, be applicable to the condition of the difficult banding because of various reasons, waterproofing membrane provides the skeleton for the banding in this structure, earth plays and supports waterproofing membrane, polyurethane foaming joint filling agent can seal the gap and the hole of waterproofing membrane and road surface, this kind of combination can adapt to the road surface condition of different roughness, it is effectual to seal the thick liquid; this combination banding structure construction is simple, maneuverability is strong, and the grout construction back is bare leaking the waterproofing membrane manual work outside all around to the region of will being in the milk and is demolishd, furthest reduces construction cost. The edge sealing structure has very wide application value.

Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It should be understood, however, that these implementation details should not be used to limit the invention. That is, in some embodiments of the invention, details of these implementations are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.
As shown in fig. 1-2, the utility model relates to a novel grouting composite road surface construction edge sealing structure, which comprises a flexible road surface grouting layer 1, wherein the flexible road surface grouting layer is a large-aperture asphalt mixture paving layer, a waterproof roll material layer 3 is paved at the side edge part of the flexible road surface grouting layer 1, the waterproof roll material is a high-polymer modified waterproof roll material, is a curlable sheet-shaped waterproof material, has the length of 10m, the width of 1.5m and the thickness of 2mm, can be randomly cut into different shapes, the waterproof roll material is cut according to the field condition, the cutting thickness of the waterproof roll material layer 3 is ensured to be more than 5cm higher than the thickness of the flexible road surface grouting layer 1, the part of the waterproof roll material layer 3 is pressed at the lower part of the flexible road surface grouting layer 1, the length of the lower part of the flexible road surface grouting layer 1 is 10, the other part of the waterproof roll material layer 3 is arranged at the side edge part of the flexible pavement grouting layer 1, a first foaming joint filling layer 4-1 and a second foaming joint filling layer 4-2 are arranged at the outer side of the waterproof roll material layer 3, the waterproof roll material layer 3 is fixed through the first foaming joint filling layer 4-1 and the second foaming joint filling layer 4-2, clay or sand or gravel is randomly obtained at the periphery of a grouting area by the clay and the polyurethane foaming joint filling layer, local materials are obtained, the purpose of supporting the waterproof roll material is achieved, a polyurethane foaming joint filling agent, specifically a polyurethane foaming filling elastic sealing material, is selected in the foaming joint filling layer in the clay and polyurethane foaming joint filling layer, and is sprayed to a part to be constructed through a matched glue applying gun or a manual spray pipe during construction, so that the forming, foaming, bonding and sealing processes can be completed in a short time, the foaming joint mixture is a quick-drying joint mixture with the surface drying time within 15 minutes, the outer side of the first foaming joint mixture layer 4-1 is a pavement edge part 5, and the outer side of the second foaming joint mixture layer 4-2 is an adjacent pavement 2.
