Background technology
China's economy is in high-speed development period at present, and the annual road building a large amount of various grade is wherein concrete road greatly.Current domestic concrete road mainly adopts cast-in-place concrete construction technique, needs on-the-spot formwork supporting plate, assembling reinforcement, concreting, the work progresss such as concrete curing.It is mainly as follows to there is drawback in cast-in-situ concrete production technology:
Production efficiency is low, the manpower of at substantial, long construction period.Site operation mainly adopts manual work, and product quality not easily ensures.Big for environment pollution, poured in place concrete produces noise, sewage, the environment pollutions such as waste material.Road surface is removed or when discarding, ground surface material forms building waste, cannot reuse, cause the wasting of resources.The impact of construction climate is large.Rainy season and unfavorable construction cold season, cause the seasonal downtime longer.Therefore, the above shortcoming of cast-in-situ concrete road, has become the bottleneck of restriction concrete road industrialization development.
And precast concrete road has following advantage:
1) production efficiency is high, saves manpower, is conducive to realizing highway construction industrialization.Precast concrete road produces component in millworkization, and site machineryization is installed, and production efficiency is manually produced far above scene, and change construction worker is industrial worker, promotes industry industrialization level.
2) construction period is short, reduces Climatic risk.The weatherproof of precast concrete road in-site installation, winter still can construct, and without the need to concrete curing, substantially reduces the road construction cycle, reduces the economic loss because climate change brings.
3) civilized construction and environmental requirement is met.Precast concrete road in-site installation noiselessness, sewage, airborne dust, can keep the operating environment that job site is good, little to surrounding environment influence.
4) good product quality.Precast concrete road product is that factory's shaping standardization is produced, and achieve Specialty Design, make, the cast-in-situ concrete road than field fabrication in product quality and security performance is more guaranteed.
5) resource utilization is high, is conducive to social sustainable development.Precast concrete road can realize disassembling reusing, and when road needs to remove or move, concrete pavement slab can be disassembled resettlement and reuse.And industrial waste and circular regeneration material can be used in a large number in precast concrete road process of factory production, to economizing on resources, energy-saving and emission-reduction are significant, are conducive to social sustainable development.
Can predict: industrialized level is higher, the precast concrete road of better quality will be the developing direction of highway construction.Promoting the use of lifting road engineering industry level of precast concrete road, reduces construction cost, accelerates construction period, reduce Construction on Environment impact and all have positive role.
