Embodiment Construction
[0036] The following are preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also considered as the present invention. protection scope of the invention.
[0037] The first aspect of the present invention provides a green upgrade structure transformation method for concrete pavement, the construction flow chart is as follows figure 1 shown, including the following steps:
[0038] 1) Concrete pavement treatment: milling 5~10cm on the surface of the concrete pavement 1, and cutting the real seam of the concrete pavement 1 to form a pavement filling groove 2 with a width of 10~20cm, and remove the dust on the surface of the concrete pavement 1 ;
[0039] 2) Concrete pavement joint treatment: firstly install the pavement filler 3 in the pavement filler laying groov...

The invention provides a green upgrading structure of concrete pavement and a reconstruction method thereof. The A reconstruction method comprises the following steps: concrete pavement treatment, concrete pavement joint treatment, reinforcing bar mesh layer laying, filling and excavating partition box laying, recycling concrete layer construction, upper reinforcement layer and partition mortar layer construction, water-proof base layer and asphalt mixture surface layer construction, filling and excavating partition box taking out and draining and storing water partition belt laying. The method provided by the invention realizes the full utilization of the milling material of the concrete pavement and saves the building resources. At the same time, in order to prevent the crack from reflecting, the upper reinforced layer and the spacer mortar layer can effectively prevent the crack from blocking the reflection channel and enhance the integrity of the pavement structure. It reduces thedifficulty of setting up the water drainage and storage partition belt in the later period and improves the compaction effect of the pavement structure. The utility model meets the needs of storing and utilizing rainwater, greening construction of partition belt and assembling installation of curb stone, and effectively improves the construction efficiency on site.
Description
technical field [0001] The invention relates to the technical field of road engineering, in particular to a concrete pavement green upgrade structure and reconstruction method with good structural integrity, high on-site construction efficiency, and separation strips with drainage and storage functions. Background technique [0002] With the rapid advancement of urban construction in our country, drivers and passengers have higher and higher requirements for road comfort and safety. Due to the large driving noise and poor flatness of concrete pavement, its traffic capacity and forming comfort are often lower than that of asphalt pavement. In this regard, in order to improve driving comfort and safety and improve road traffic capacity, a series of concrete pavement needs to be transformed into asphalt pavement. [0003] At present, the common structure of concrete pavement reconstruction is to dig out all the surface course of the old concrete pavement or the seriously damag...
