Problems solved by technology

[0003] Porous pavements have been used in developed countries such as Europe and the United States, but the strength of porous pavements is very low, and they cannot withstand medium or higher traffic pressure (20MPa), so the application range is very small
Some porous pavements use concrete additives, causing water and environmental pollution

example 1

[0024] Raw materials: 1 part of cement, 0.25 parts of water, 5.3 parts of stone (including 15 parts of stone under the 11mm sieve and 9.51mm sieve, 45 parts of 4.76mm sieve and 9.51mm sieve, 2.38mm sieve and 20 parts under 4.76mm sieve, 8 parts under 1.19mm sieve and 2.38mm sieve, 6 parts under 0.595mm sieve and 1.19mm sieve, 3 parts under 0.297mm sieve and 0.595mm sieve 0.149mm sieve and 0.297mm sieve are 2 parts, 0.074mm sieve and 0.149mm sieve are 1 part;

[0025] step:

[0026] A. Mix raw cement, water and stones according to the above proportions into concrete and put them into the pavement formwork for pouring;

[0027] B. Vibrate the pavement after pouring with a vibrator, vibrate once per square meter, and last for 3 minutes each time;

[0028] C. Curing. After the concrete is paved, cover it with a plastic film for 24 hours, then sprinkle water every four hours during the day for maintenance, and once every 8 hours at night for 28 days.

example 2

[0030] 1 part of cement, 0.27 parts of water, 5.4 parts of stone, the duration of vibration is 4 seconds, and the curing is 29 days. The rest are the same as in Example 1.

example 3

[0032] 1 part of cement, 0.3 part of water, 5.7 parts of stone, the duration of vibration is 5 seconds, and curing is 30 days, and the rest is the same as Example 1.

[0033] The sieve diameter refers to the diameter of the sieve holes. After the stones are sieved by a standard sieve, stones with different particle sizes are formed. Stones with various particle sizes are mixed with cement and water according to the above weight ratio to form high-strength porous concrete.

[0034] The above proportions are weight proportions.

Abstract

The invention discloses a high-strength pore concrete pavement and a preparation method thereof. The purpose of the invention is to provide the high-strength pore concrete pavement and the preparation method thereof. The high-strength pore concrete pavement comprises the raw materials by weight portion: 5.3-5.7 portions of building stones, 1 portion of cement and 0.25-0.3 portion of water. The method comprises the following steps of: A, mixing the building stones, the cement and the water into concrete according to the above proportion, putting the concrete into a pavement template to be watered; B, vibrating the watered pavement in the step A by a vibrator, wherein vibrating one square meter of pavement for one time, and lasting 3-5 seconds in one time; C, maintenance: after the concreteis paved, using a plastic film to be covered on the concrete for 24 hours, then carrying out watering maintenance for one time every 4 hours during the day, and carrying out watering maintenance for one time every 8 hours at night; and carrying out maintenance for at least 28 days, and finally obtaining a product. The method is mainly used for preparing the high-strength pore concrete pavement.

Description

technical field [0001] The invention relates to a concrete pavement and a preparation method thereof, in particular to a high-strength porous concrete pavement and a preparation method thereof. Background technique [0002] The pavement materials commonly used today can generally be divided into two categories, one is asphalt concrete and the other is cement concrete. The two types of common pavement materials are basically impermeable, and rainwater will quickly form surface runoff on the road surface, which can easily cause floods and urban floods. At the same time, there are also a large number of pollutants, such as solid particles, domestic waste, oil and other organic pollutants and nutrients (nitrogen and phosphorus), etc., accompanied by rain and floods. In addition, most cities in China are short of water, and rainwater, as a precious resource, directly enters the drainage system along the road and flows into rivers, which is wasted in vain. With the intensificati...
