Water-permeable fabricated concrete pavement and construction method thereof

Abstract

The invention discloses a water-permeable fabricated concrete pavement and a construction method thereof. The pavement comprises a water seepage interlayer, a water storage base layer, a water-permeable base layer and a water-permeable concrete surface layer which are sequentially laid on a natural rammed foundation from bottom to top, the water-permeable concrete surface layer is formed by splicing a plurality of concrete prefabricated slabs, and the concrete prefabricated slabs are connected through grooves and tongues and grooves of tenons. The water storage base layer is formed by paving granular aggregates, and the bearing capacity and the water storage cooling capacity of the base layer are provided at the same time through the granular aggregates; the water seepage interlayer is composed of an upper seepage-proofing layer and a lower isolation layer, the upper seepage-proofing layer is connected with the water storage base layer, the lower isolation layer is connected with the natural rammed earth foundation, and the water seepage interlayer is provided with a drainage slope and can transversely drain seepage water of the water storage base layer to longitudinal blind ditches in the two sides of the road surface. The water storage and drainage capacity of the pavement is excellent, field construction is easy, the construction quality is uniform and stable, and the influence degree of the construction process on traffic is smaller.

Description

technical field [0001] The invention belongs to the field of pavement construction, and in particular relates to a permeable assembled concrete pavement and a construction method thereof. Background technique [0002] Impervious pavement with high strength, good durability and easy construction has been widely used in road engineering in my country. However, in today's abnormal global climate, impervious pavement blocks the exchange of matter and energy between the atmosphere and the surface. Detention on the road surface has caused problems such as water pollution, urban waterlogging, heat island effect, and decline in the anti-skid performance of the road surface, which seriously affects traffic safety. [0003] Whether it is new roads or road surface maintenance and repairs in China, most of them use on-site pouring, and they all face problems such as long on-site operation time, difficulty in accurately controlling quality, large construction disturbances, affecting traff...
