Fabricated prestressed high-strength concrete pavement

Abstract

The invention discloses a fabricated prestressed high-strength concrete pavement. The fabricated prestressed high-strength concrete pavement comprises two or more single plates, prestressed tendons, prestressed anchorage devices and fabricated parts. A veneer is made of high-strength concrete, thickness of the veneer is 6-10 cm, transverse and longitudinal crossed prestressed tendon hole channelsare formed in the veneer, and bent hole channels are formed in the crossed points; more than two veneers are mutually inserted along the transverse direction and / or the longitudinal direction, the prestressed tendons are arranged along a center line of the veneer body and are inserted into corresponding prestressed tendon ducts, the prestressed tendons are in a transverse and longitudinal crossedstate in space, and a distance between every two adjacent transverse or longitudinal prestressed tendons is 1-3m, the prestressed tendons extend out of the end single plates and then are anchored andfixed through the prestressed anchorage devices to form assembling and splicing units. And more than one assembling and splicing unit is connected through assembling pieces to form a pavement. The fabricated prestressed high-strength concrete pavement is advantaged in that the thickness of a pavement slab is reduced, and on-site rapid assembly can be realized.

Description

technical field [0001] The invention relates to the technical field of concrete pavement structures, in particular to an assembled prestressed high-strength concrete pavement. Background technique [0002] Concrete pavement refers to a pavement that uses cement concrete slabs as the surface layer. It refers to the pavement structure composed of cement concrete slab as the surface layer, base layer and cushion layer, also known as rigid pavement. The prefabricated concrete pavement is a pavement that is prefabricated in the factory and then paved at the construction site. The disadvantage is that the pavement is generally thick and difficult to connect, and cannot be widely used; the prestressed concrete pavement Stress tendons are arranged obliquely, the weaving effect is not good, the loss of prestress is large, the construction process is relatively complicated, the construction period is long, and the concrete pavement of the pavement is also relatively thick, which incr...

The prefabricated concrete pavement is a pavement that is prefabricated in the factory and then paved at the construction site. The disadvantage is that the pavement is generally thick and difficult to connect, and cannot be widely used; the prestressed concrete pavement Stress tendons are arranged obliquely, the weaving effect is not good, the loss of prestress is large, the construction process is relatively complicated, the construction period is long, and the concrete pavement of the pavement is also relatively thick, which increases the difficulty of on-site paving
