The utility model discloses a high-performance fiber cement-based composite material expansion joint structure of a continuous reinforced pavement, which comprises a base layer, a middle layer, a synchronous gravel seal and an asphalt concrete surface layer which are arranged from bottom to top in sequence; the middle layer comprises a high-performance fiber cement-based composite material layer arranged in the middle of the middle layer and continuous reinforced concrete arranged on two sides of the high-performance fiber cement-based composite material layer, an anti-crack paste is arranged between the joint of the continuous reinforced concrete and the high-performance fiber cement-based composite material layer and the synchronous gravel sealing layer, and longitudinal steel bars horizontally penetrating through at least one side of the continuous reinforced concrete and the high-performance fiber cement-based composite material layer are arranged in the middle layer. Use the utility model discloses, need not to set up expansion joint device, the road surface is continuous structure, adopts combined material's deformation as the deformation compensation under the road surface structure temperature effect, and road surface can reach seamless effect, improves the driving travelling comfort.
Description
Technical Field
The utility model relates to a highway, urban road pavement design and construction field, concretely relates to continuous reinforcement road surface high performance fiber cement base combined material expansion joint structure.
Background
The expansion joint device for processing the end part of the existing composite pavement is similar to the expansion joint of a bridge, the expansion joint is mostly arranged for a certain length, and the expansion joint compensates the length change of the pavement structure under the temperature change by adopting the expansion joint device. Although the expansion joint can effectively release the internal stress of the material under the temperature change, the expansion joint still exists in the road, the expansion joint can vibrate when a vehicle passes through, and particularly when the construction quality of the expansion joint is poor, the passing comfort of the vehicle is poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a continuous arrangement of reinforcement road surface high performance fiber cement base combined material expansion joint structure need not to set up expansion joint device, and the road surface is continuous structure, adopts combined material's deformation as the deformation compensation under the road surface structure temperature effect, and road surface can reach seamless effect.
In order to solve the technical problem, the utility model adopts the technical scheme that: a high-performance fiber cement-based composite material expansion joint structure for a continuous reinforced pavement comprises a base layer, an intermediate layer, a synchronous gravel seal layer and an asphalt concrete surface layer which are sequentially arranged from bottom to top; the middle layer comprises a high-performance fiber cement-based composite material layer arranged in the middle of the middle layer and continuous reinforced concrete arranged on two sides of the high-performance fiber cement-based composite material layer, an anti-crack paste is arranged between the joint of the continuous reinforced concrete and the high-performance fiber cement-based composite material layer and the synchronous gravel sealing layer, and longitudinal steel bars horizontally penetrating through at least one side of the continuous reinforced concrete and the high-performance fiber cement-based composite material layer are arranged in the middle layer.
Further, the intermediate level still includes the horizontal reinforcing bar of a plurality of equidistance settings, horizontal reinforcing bar sets up the height the same.
Compared with the prior art, the beneficial effects of the utility model are that:
use the utility model discloses, need not to set up expansion joint device, the road surface is continuous structure, adopts combined material's deformation as the deformation compensation under the road surface structure temperature effect, and road surface can reach seamless effect, improves the driving travelling comfort.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure, 1, a high-performance fiber cement-based composite material; 2. continuously reinforced concrete; 3. synchronously breaking a stone seal layer; 4. an asphalt concrete surface layer; 5. a base layer; 6. longitudinal reinforcing steel bars; 7. transverse reinforcing steel bars; 8. the anti-crack sticker.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, and the present embodiment is based on the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the present invention is not limited to the following embodiments.
The utility model provides a like the combined type road surface expansion joint device shown in figure 1, high performance fiber cement base combined material 1 is as the telescoping device of continuous reinforced concrete 2, is synchronous rubble seal 3 and asphalt concrete surface course 4 above being located the expansion joint, and what lower pavement was road base 5. The high-performance fiber cement-based composite material 1 and the continuous reinforced concrete 2 are connected together by adopting longitudinal steel bars 6, and the longitudinal internal force of a structural layer is transmitted. The transverse reinforcing steel bars 7 bear the transverse internal force of the road surface. In order to prevent the asphalt concrete surface layer 4 from generating reflection cracks, an anti-crack sticker 8 is arranged on the top of the joint of the 1 and the 2.
The utility model discloses utilize the higher bending of high performance fiber cement base combined material 1 to draw the performance, can compensate the deformation of continuous reinforced concrete 2 under the temperature variation.
The utility model provides a flexible scope will be with the limit of high performance fiber cement base combined material 1 draw strain and continuous reinforced concrete 2's temperature coefficient of deformation comprehensive consideration, reachs specific implementation length through calculating.
Through the utility model discloses, 2 road surfaces of reinforced concrete can accomplish seamless effect in succession, and when the vehicle passed through, the expansion joint can not take place vibrations, improves the driving travelling comfort.
It is right only to go up the preferred embodiment of the utility model discloses a it is not right the utility model discloses a scope is injectd, the event is not deviating from the utility model relates to an under the prerequisite of spirit, ordinary engineering technical personnel in the field is right the equivalent change or the decoration that structure, characteristic and principle do, all should fall into the utility model discloses the protection within range of applying for a patent.
