Stone texture-like permeable concrete ground and construction method thereof

Abstract

The invention relates to a stone-simulating pervious concrete floor and a construction method thereof. The concrete floor includes a tamped foundation, a crushed stone layer, a pervious concrete structural layer and a pervious concrete surface layer from bottom to top; the pervious concrete surface layer is a stone-simulating pervious concrete surface layer, which adopts the following materials and weight ratio: 2100-2300kg / m<3> of river sand; 325-335kg / m<3> of cement; 39-41kg / m<3> of silicon power; 24-26kg / m<3> of Grade I coal ash; 3.4-3.6kg / m<3> of water reducer and 78-80kg / m<3> of tap water. The invention leads the pervious concrete road surface to have water permeability and decoration simultaneously, and improves the water-permeable and air-permeable effect of the concrete road surface on the premise of ensuring the strength of the road surface and having the texture of the concrete road surface.

Description

technical field [0001] The invention relates to a concrete pavement and a construction method thereof. Background technique [0002] Due to global climate change, overexploitation of groundwater and environmental pollution, many available water sources have been destroyed, and my country is facing the threat of a wide range of water shortages, especially in the vast areas of the north, which is becoming a constraint on my country's economy. bottlenecks in development and social progress. On the other hand, my country's urbanization process is progressing rapidly, and large areas of the ground are covered with dense concrete, causing a large amount of rainwater loss, and often causing traffic paralysis due to excessive rainfall exceeding the drainage capacity of municipal works. Therefore, constructing permeable pavement, returning rainwater to the ground, replenishing groundwater sources, and maintaining the ecological balance of groundwater is a systematic technology that i...

Problems solved by technology

[0005] Existing permeable concrete pavement, such as the Chinese patent with publication number CN 101003962, its pavement structure is composed of compacted soil layer, ordinary concrete base, permeable concrete structure layer and permeable concrete surface layer from bottom to top. The pavement surface is also porous and rough without decorative texture, and it is also subject to some restrictions when it is used on the ground with landscape requirements.

However, if the decorative texture is made on the permeable concrete pavement, the surface of the decorative texture must be dense, which will reduce the water permeability and air permeability of the pavement. How to make the permeable concrete pavement both water permeable and decorative has become an urgent technical problem to be solved
