Problems solved by technology

[0003] Low production efficiency, consume a lot of human resources, long construction period
On-site construction mainly adopts manual work, and product quality is not easy to guarantee
Great environmental pollution, on-site concrete pouring produces noise, sewage, waste and other environmental pollution
When the pavement is demolished or abandoned, the pavement materials will form construction waste, which cannot be reused, resulting in a waste of resources
Construction is greatly affected by the climate
Rainy and cold seasons are unfavorable for construction, resulting in longer seasonal downtime
Therefore, the above shortcomings of cast-in-place concrete roads have become a bottleneck restricting the industrialization of concrete roads

Embodiment 1

[0027] A preparation method of high-strength frost-resistant concrete is characterized in that the method comprises the following steps:

[0028] Add 300 parts of cement, 60 parts of quicklime, 600 parts of aggregate, 2.5 parts of activator and 5.8 parts of amphoteric dispersant into 300 parts of water, stir and mix evenly, control the dispersion degree of the slurry at 18cm, the temperature at 45°C, and the stirring speed 650r / min;

[0029] The material obtained in the above steps is poured, and after pouring, it is sent to a static chamber with a temperature of 50°C and a humidity of 60°C for thickening for 3 hours;

[0030] After thickening, the material is demolded and cut to obtain the green body of the required specification and size, and then the green body is

[0031] Send it to the autoclave for steam curing for 2 hours. After leaving the autoclave, it will be naturally cured for one week to obtain the final high-strength frost-resistant concrete.

[0032] Wherein t...

Embodiment 2

[0046] Add 300 parts of cement, 60 parts of quicklime, 600 parts of aggregate, 1 part of activator and 8 parts of amphoteric dispersant into 300 parts of water, stir and mix well, control the dispersion degree of the slurry at 18 cm, the temperature at 45 °C, and the stirring speed 650r / min;

[0047] The material obtained in the above steps is poured, and after pouring, it is sent to a static chamber with a temperature of 50°C and a humidity of 60°C for thickening for 3 hours;

[0048] After the thickening is completed, the material is demoulded and cut to obtain the green body of the required specification and size, and then the green body is sent to the autoclave for steam curing for 2 hours. After leaving the autoclave, it is naturally cured for a week to obtain the final high-strength antifreeze concrete;

[0049] All the other preparations are the same as in Example 1.

Embodiment 3

[0051] Add 400 parts of cement, 10 parts of quicklime, 500 parts of aggregate, 2.5 parts of activator and 5.8 parts of amphoteric dispersant into 300 parts of water, stir and mix evenly, control the dispersion degree of the slurry at 18cm, the temperature at 45°C, and the stirring speed 650r / min;

[0052] The material obtained in the above steps is poured, and after pouring, it is sent to a static chamber with a temperature of 50°C and a humidity of 60°C for thickening for 3 hours;

[0053] After the thickening is completed, the material is demoulded and cut to obtain the green body of the required specification and size, and then the green body is sent to the autoclave for steam curing for 2 hours. After leaving the autoclave, it is naturally cured for a week to obtain the final high-strength antifreeze concrete;

[0054] All the other preparations are the same as in Example 1.

Abstract

The invention discloses a prefabricated concrete road. The prefabricated concrete road comprises a plurality of concrete road modules, wherein square notches are formed in the four corners of each concrete road module, and a tongue-and-groove is formed in each corner; through holes are formed in every two adjacent tongues-and-grooves, and each concrete road module is provided with four through holes including two horizontal through holes and two longitudinal through holes; and the concrete road modules, horizontal connecting shafts and longitudinal connecting shafts are used in a matched mode.The prefabricated concrete road is assembled by the concrete road modules, and in particular, quick assembly and road paving can be achieved and the installation speed is high.

Description

technical field [0001] The invention relates to a prefabricated assembled concrete pavement structure. Background technique [0002] At present, the society builds a large number of roads of various grades, a large part of which is concrete roads. At present, domestic concrete roads mainly adopt cast-in-place concrete construction technology, which requires on-site support formwork, binding steel bars, pouring concrete, concrete curing and other construction processes. The disadvantages of the cast-in-place concrete production process are mainly as follows: [0003] The production efficiency is low, a large amount of human resources are consumed, and the construction period is long. The on-site construction mainly adopts manual operation, and the product quality is not easy to guarantee. Great environmental pollution, on-site pouring of concrete produces noise, sewage, waste and other environmental pollution. When the pavement is demolished or abandoned, the pavement mat...
