Description
The application is the patent No. 201510486778.2, and the applying date is August in 2015 11, and entitled " one kind is anti-
The divisional application of the high solidifying soil prepackage road of folding intensity ".
Technical field
The present invention relates to a kind of concrete road of High anti bending strength.
Background technology
China's economy is currently under high-speed development period, the annual road for building a large amount of various grades, wherein very big one
It is concrete road to divide.Country's concrete road mainly uses cast-in-place concrete construction technique, it is necessary to which live formwork supporting plate, is tied up at present
Wire-tie, casting concrete, the work progress such as concrete curing.It is mainly as follows to there is drawback in cast-in-place concrete production technology：
Low production efficiency, expends substantial amounts of human resources, long construction period.Site operation mainly uses manual work, product matter
Amount is difficult to ensure.Big for environment pollution, poured in place concrete produces noise, sewage, the environmental pollution such as waste material.Road surface remove or
When discarded, ground surface material formation building waste, it is impossible to reuse, cause the wasting of resources.Climate influence of constructing is big.Rainy season and
Cold season unfavorable construction, causes the seasonal downtime longer.Therefore, the disadvantage mentioned above of cast-in-place concrete road, it has also become system
The about bottleneck of concrete road industrialization development.
And precast concrete road has the advantage that：
1）Production efficiency is high, saves human resources, is advantageously implemented road engineering industrialization.Precast concrete road is in factory's machine
Tool metaplasia produces component, and site machineryization is installed, production efficiency production artificial far above scene, change builder into industrial worker,
Lift industry industrialization level.
2）Construction period is short, reduces Climatic risk.Precast concrete road in-site installation weatherproof, winter still may be used
Construction, and without concrete curing, the road construction cycle is substantially reduced, reduce because of the economic loss that climate change is brought.
3）Meet civilized construction and environmental requirement.Precast concrete road in-site installation is noiseless, sewage, airborne dust, can protect
The good operating environment in job site is held, it is small to surrounding environment influence.
4）Good product quality.Precast concrete road product is factory's shaping standard metaplasia production, realizes Specialty Design, makes
Make, the cast-in-place concrete road than making in product quality and security performance is more guaranteed.
5）Resource utilization is high, is conducive to social sustainable development.Precast concrete road, which can be realized, disassembles reuse,
When road needs to remove or moved, concrete pavement slab can disassemble resettlement and reuse.And concrete dirt road
Industrial waste and circular regeneration material, to economizing on resources, energy-saving and emission-reduction meaning weight can be largely used in the process of factory production of road
Greatly, social sustainable development is conducive to.
It is contemplated that：Industrialized level is higher, the precast concrete road of better quality by be road engineering development side
To.Promoting the use of to lifting road engineering industry level for precast concrete road, reduces construction cost, accelerates construction week
Phase, reducing Construction on Environment influence all has positive role.
