Embodiment Construction

[0050]Referring to the embodiment shown in Figure 1, this imitation stone texture permeable concrete floor includes a compacted foundation 1, a gravel layer 2, a permeable concrete structure layer 3, and a permeable concrete surface layer 4 from bottom to top, and is characterized in that: the permeable concrete surface Layer 4 is a stone-like texture permeable concrete surface layer; the raw materials used in the permeable concrete surface layer 4 and the weight ratio of concrete per cubic meter are:

[0051] (a), the fine aggregate is river sand, and the addition amount is 2200kg / m 3 ;The river sand is sieved with sieves of 5mm, 2.5mm and 0.16mm, and the gradation is adjusted to: 60-70% of the particle size of 1.25-5mm, and 30-40% of the particle size of 1.25mm or less;

[0052] (b), 42.5 ordinary Portland cement: 330kg / m 3 ;

[0053] (c), silica fume: 40kg / m 3 ;

[0054] (d), Class I fly ash: 25kg / m 3 ;

[0055] (e), water reducer: 3.5kg / m 3 ;

[0056] (f), tap wate...

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...
