Description

A kind of concrete road of Fast Installation
Technical field
The present invention relates to a kind of concrete road of Fast Installation.
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, production Quality is difficult to ensure.Big for environment pollution, poured in place concrete produces noise, sewage, the environmental pollution such as waste material.Tear open on road surface When removing or discarding, ground surface material formation building waste, it is impossible to reuse, cause the wasting of resources.Climate influence of constructing is big.Rain Season and cold season unfavorable construction, cause the seasonal downtime longer.Therefore, the disadvantage mentioned above of cast-in-place concrete road, into To restrict the 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 work Factory's mechanization production component, site machineryization is installed, and production efficiency is far above the artificial production in scene, and change builder is industry work People, lifts 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.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention is provided, the invention provides a kind of pin-connected panel Pre-coagulation dirt road Road.The road includes concrete pavement slab, and road deck is prefabricated in processing factory, is transported to job site positioning assembly, road surface Slab geomitry size, is determined according to the number of track-lines and design grade of design requirement.
To achieve these goals, the technical solution adopted by the present invention is:A kind of concrete road of Fast Installation, four Individual prefabricated board, the both sides of described prefabricated board, which are provided between the hole for placing steel strand wires, adjacent prefabricated board, passes through steel Twisted wire is connected;The a diameter of 14.50mm of steel hinge line,
Four sides of described prefabricated board, which are respectively provided between the hole with placement steel strand wires, adjacent prefabricated board, passes through steel strand wires Connection;
Four prefabricated boards using steel hinge line and constitute a road surface unit by steel connecting plate band on the outside of prefabricated board;
Prefabricated board between adjacent is also equipped with connecting bond structure, and described connection bond structure includes the shearing resistance cooperated Convex key and the recessed key of shearing resistance;
The convex key of described shearing resistance, which is one, has the pedestal of the raised conical surface;The recessed key of described shearing resistance, which is one, has depression cone The pedestal in face, the raised conical surface can be with depression cone match.
Two medial extremitys of described prefabricated board are mounted on the convex key of shearing resistance, and the side for corresponding prefabricated board is provided with The recessed key of shearing resistance.
The convex key of described shearing resistance and the recessed key of shearing resistance are embedded into prefabricated board side respectively, and are welded with anchor rib.
One block of rubber slab is set between described steel connecting plate band and prefabricated board plate contact surface.
Yellow sand is filled with gap between adjacent prefabricated board.
The material of described prefabricated board, is calculated by weight to 400-450 parts of cement, 40-90 parts of flyash, sand 600-700 Part, 100 parts of water, 0.2-0.4 parts of nylon fiber, 10-15 parts of calcium metasilicate, 10-13 parts of neopelex, carborundum 11-16 parts of powder.
The beneficial aspects of the present invention:
The road includes concrete pavement slab, and road deck is prefabricated in processing factory, is transported to job site positioning assembled. Road deck physical dimension, is determined according to the number of track-lines and design grade of design requirement.
For road surface plate convenient transportation, quick for installation, plate is divided into multiple by the ratio according to road deck short side and long side Species and model.
To ensure that fracture, breakage, the linkage interface between plate and plate do not occur under heavy-duty vehicle repeated action for road deck Place, there is provided some anti-shearing connecting keys of positioning.
To give full play to the bearing capacity of every block of plate, the present invention uses soap-free emulsion polymeization post-tensioned prestressing steel hinge line, and passes through plate Outside steel connecting plate band, an organic whole is connected into by adjacent four blocks of plates.
Under buffering heavy-duty vehicle repeated actions, 10-15mm gaps to be reserved at linkage interface, are filled with yellow ground, shape Into being flexible coupling.
Using special concrete batching, the prefabricated board made has preferable frost resistance.
