Embodiment Construction

[0045] The following is attached Figure 1-4 The application is described in further detail.

[0046] refer to figure 1 , in this embodiment, the original two-way four-lane road surface is transformed into a two-way six-lane road surface, that is, two new lanes are added on the basis of the original two-way four-lane road surface to alleviate traffic pressure, and the original two-way four-lane road surface is upgraded at the same time. Improve road conditions. Specifically, the two road surfaces where the two original one-way lanes are located are successively set as the old road surface 2 on the inside and the old road surface 2 on the outside. The old road surface 2 is constructed first, and then the new road surface 1 is expanded.

[0047] The sequence of construction on the old pavement 2 is as follows: first, construct the inner repair surface 21 on the surface of the old road surface 2 on the inner side. The direction of the center line is inclined downward, and the ...

Abstract

The invention relates to a drainage system and a construction method for a road surface in a road reconstruction and extension project communication keeping stage, which are applied to the field of road drainage technology, and comprise an inner side repair surface paved on the surface of an inner side old road surface and an outer side repair surface paved on the surface of an outer side old road surface, the inner side repairing surface and the outer side repairing surface are obliquely and downwards arranged in the direction away from the center line of the road, and the inner side repairing surface and the outer side repairing surface are coplanar; the temporary groove is arranged between the old road surface and the new road surface, and a temporary drainage ditch is arranged in the temporary groove. The construction method has the effects that the construction of the new pavement does not cause interference on the drainage system of the old pavement, so that the old pavement and the joint of the old pavement and the new pavement are not easy to generate water accumulation, and the normal passage of the road can be ensured.

Description

technical field [0001] The application relates to the field of road drainage technology, in particular to a drainage system and a construction method for road surface in the maintenance stage of highway reconstruction and expansion projects. Background technique [0002] As the traffic flow continues to increase year by year, the roads built in the early days can no longer meet the current traffic situation at the current stage. In addition, due to the continuous load of large tonnage, the road surface has various degrees of disease such as subsidence, cracks, and bulges. The service level of the roads under construction has dropped significantly. In order to upgrade and reconstruct the roads built in the early stage and improve the traffic situation, on the one hand, it is necessary to repair the damaged road surface, and on the other hand, it is necessary to widen the road surface on the basis of the original road surface, for example, to transform the original two-way fou...
