Multilayer precast paved road
Provided is a multilayer precast paved road that enables simple coupling between upper pavement panels and lower pavement panels using joint members and enables easy and quick assembly and removal without requiring a large number of processes. A multilayer precast paved road including a plurality of precast lower pavement panels laid on a road panel and a plurality of precast upper pavement panels laid on upper surfaces of the lower pavement panels is configured such that the lower pavement panels 3 and the upper pavement panels are arranged in a zigzag manner, and joint members are provided to lie between upper and lower joining surfaces of the lower pavement panels and the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through engagement or fitting between the lower pavement panels and the upper pavement panels achieved by the joint members.
1. A two-layer precast paved road comprising:
a plurality of precast lower pavement panels laid on a road panel; and
a plurality of precast upper pavement panels laid on upper surfaces of the lower pavement panels,
wherein the lower pavement panels and the upper pavement panels are arranged in a zigzag manner, and
joint members are provided to lie between upper and lower joining surfaces of the lower pavement panels and the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through engagement or fitting between the lower pavement panels and the upper pavement panels achieved by the joint members,
wherein cup-shaped receiving members are embedded in and fixed to upper surfaces of the lower pavement panels and lower surfaces of the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through fitting of upper half portions and lower half portions of the joint members to the respective receiving members,
wherein the upper pavement panels and the lower pavement panels are coupled to each other with the joint members through the fitting between a plurality of protrusions formed over the entire inner peripheral surface of a cylindrical portion of the receiving members and a plurality of protrusions similarly formed over the entire outer periphery of a disk portion of the joint members, and
wherein each of the receiving members includes a bottom surface portion with a circular shape, a side surface portion with a tapered cylindrical shape extending with a diameter increasing from the bottom surface portion toward an upper side, and the cylindrical portion with a low height standing from the side surface portion in parallel and forming an opening portion peripheral edge of each of the receiving members.
2. The two-layer precast paved road according to claim 1 , wherein a certain upper pavement panel of the upper pavement panels is made of a hollow pavement panel having a hollows penetrating in a road extending direction and including a water stop seal to surround an opening portion of the hollow.
3. The two-layer precast paved road according to claim 2 , wherein the hollow pavement panel is made of any of plastic, carbon fiber reinforced concrete, and FRP ferroconcrete and includes a non-contact power supply coil disposed inside the hollow.
4. The two-layer precast paved road according to claim 1 , wherein the upper pavement panels are made of a water-permeable material or a running noise reducing material with a porous structure or a slit surface.
5. The two-layer precast paved road according to claim 1 , wherein the lower pavement panels have water stop seals on side surfaces that face the adjacent lower pavement panels.
6. A two-layer precast paved road comprising:
a plurality of precast lower pavement panels laid on a road panel; and
a plurality of precast upper pavement panels laid on upper surfaces of the lower pavement panels,
wherein the lower pavement panels and the upper pavement panels are arranged in a zigzag manner, and
joint members are provided to lie between upper and lower joining surfaces of the lower pavement panels and the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through engagement or fitting between the lower pavement panels and the upper pavement panels achieved by the joint members,
wherein cup-shaped receiving members are embedded in and fixed to upper surfaces of the lower pavement panels and lower surfaces of the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through fitting of upper half portions and lower half portions of the joint members to the respective receiving members,
wherein the upper pavement panels and the lower pavement panels are coupled to each other with the joint members through the fitting between a plurality of protrusions formed over the entire inner peripheral surface of a cylindrical portion of the receiving members and a plurality of protrusions similarly formed over the entire outer periphery of a disk portion of the joint members, and
wherein each of the joint members includes a disk portion and cylindrical portions extending vertically from the centers of upper and lower surfaces of the disk portion, and the disk portion and the upper and lower cylindrical portions are coupled to each other with a plurality of reinforcing ribs with a triangular shape.
