Technical Field

The invention belongs to the technical field of pavement construction, and particularly relates to a municipal road rapid repairing structure and a construction method.

Background

The concept of "sponge city" was first proposed in "2012 low carbon city and regional development science and technology forum". The sponge city means that the city can rapidly permeate into the ground when raining like a sponge, can release the water stored in rainy seasons when dry, and solves the urban problem through city self-regulation.

The construction of a sponge city can not be separated from a sponge body. The urban land features conforming to the characteristics of the sponge body comprise water systems such as rivers, lakes and the like, and urban supporting facilities such as green belts, gardens, permeable ground and the like. Rainwater falls onto the sponge body and can quickly seep to the ground, and the natural ground surface has the functions of storing, purifying and recycling the rainwater, so that various urban diseases are reduced. The permeable road pavement is an important measure in sponge city construction, and covers urban roads, urban green land and square roads, residential road, urban road and other urban roads at all levels. Due to the particularity of the permeable pavement structure, the characteristics of the structure and the material of the permeable pavement structure are greatly different from those of the original road pavement. In the process of research on water permeable pavement, the state issues technical specifications of water permeable brick pavement, water permeable asphalt pavement, water permeable cement concrete pavement and the like in succession, and can guide the construction of water permeable pavement of urban roads to a certain extent.

The pervious concrete is developed and used by countries such as Europe, America, Japan and the like aiming at the defects of the road surface of the original urban road, can make rainwater flow into the ground, effectively supplements the ground water, and relieves some urban environmental problems such as rapid decline of the underground water level of the city and the like. And can effectively eliminate the harm of oil compounds on the ground and the like to the environmental pollution; meanwhile, the material is an excellent paving material which can protect underground water, maintain ecological balance and relieve urban heat island effect; it is beneficial to the benign development of human living environment, the management of urban rainwater, the prevention and treatment of water pollution and the like, and has special significance.

During the use of the concrete road, due to the influence of factors such as climate or geology, the road surface can crack, and the smoothness of vehicles running on the road surface can be seriously influenced after the road surface cracks. At present, the method for repairing the concrete pavement mostly pours new concrete at the crack of the pavement, and in order to ensure the stability of the newly added concrete and ensure that the crack can be filled with the new concrete, the adding amount of the asphalt concrete is often larger than the volume of the crack in the construction and repair process, so that the concrete forms a bulge on the originally flat pavement, the concrete pavement is uneven, and certain potential safety hazards exist.
