Description
Technical Field
The invention relates to the technical field of permeable pavements, in particular to a permeable modification technology for an impermeable concrete pavement.
Background
Rainwater infiltration is an important process of natural water circulation, and facilities such as urban hardened pavements cut off the infiltration of surface water, so that the water level of urban underground water is reduced, the ground drainage pressure is increased, and urban waterlogging is easily caused. In recent years, the method has become one of the major construction projects for city construction.
Pervious concrete structures, such as pervious cement concrete, pervious asphalt concrete, pervious resin concrete and the like, play an important role in the construction of sponge cities in China in recent years, and as the pervious pore diameter of the pervious concrete is far higher than that of pervious building blocks, the pervious rate is far higher than that of the pervious building blocks, and the existing paving process also enables the pervious concrete structures to be flexibly applicable to various road surface projects with complicated and changeable levels and elevations. The method is widely applied to places such as roads, parks, squares and districts, and plays an important role in relieving urban drainage pressure, replenishing underground water, maintaining ecological balance, relieving urban heat island effect, beautifying environment and the like. A general typical permeable concrete pavement structure comprises a permeable concrete finishing layer (30-80mm), a permeable structure layer (90-180mm), a gravel base layer (200 and 300mm are different), a rammed earth base and the like. Part of the permeable structures do not have rainwater infiltration capacity due to low permeability coefficient of regional rock soil, or are laid with waterproof geotextiles at the lower parts of the permeable structure layers for rainwater collection and recycling because regional water resources are relatively barren.
Based on the characteristics, because the paving materials of each layer of the existing non-permeable structure are not permeable, the complete excavation needs to be carried out, and when a permeable concrete structure is newly built, the engineering requirements of large-scale disassembly and large-scale construction are often met. The ground excavation depth can reach 300-500 mm. A large amount of low-quality construction waste is generated after the construction waste is removed, and a large amount of energy and land resources are consumed in the processes of transferring, storing and consuming the construction waste. When the structure is newly built, a large amount of natural resources or building materials such as sand, stone, concrete and the like need to be invested again. In addition, because the scale of the engineering excavation and the new construction is large and the period is long, the method also has certain influence on surrounding residents and the environment.
Therefore, a permeable transformation technology for the impervious concrete pavement is provided.
