Embodiment Construction

[0024] In order to better understand the present invention, the present invention will be further described below in combination with the accompanying drawings.

[0025] Such as Figure 1 to Figure 4 As shown, a prefabricated cement concrete road slab for rapid maintenance of road surfaces includes a prefabricated concrete panel 1, and two layers of metal reinforcement bars are distributed in a criss-cross pattern inside the precast concrete panel 1, and the precast concrete panel 1 is in the driving direction. Dowel bars 3 are evenly protruded from the middle of both ends of the panel, and tie bar grooves 4 are evenly arranged on both longitudinal sides of the precast concrete panel 1 .

[0026] The metal reinforcement includes an upper metal reinforcement 11 composed of No. 4 epoxy resin coated steel bars and a lower metal reinforcement 12 composed of No. 4 ordinary steel bars from top to bottom, wherein the distance between the upper metal reinforcement 11 and the precast c...

Abstract

The invention discloses a prefabricated cement pavement slab for quick pavement repair. The prefabricated cement pavement board comprises a cement concrete pavement slab, force transmission rods and internal steel bars, wherein the force transmission rods are arranged in the center of the total thickness of the two side plates of the slab at intervals; the internal steel bars are arranged in the slab and are used for preventing the slab from being warped. The pavement slab provided by the invention is fabricated in a factory building in advance and is transported to a pavement to be repaired for pavement replacement; the pavement replacement operation is performed at 10 p.m. and the pavement is opened to traffic at 5 a.m. on the next day, so that the prefabricated cement pavement slab is efficient and durable.

Description

technical field [0001] The invention belongs to the field of road engineering and relates to a prefabricated cement road slab used for rapid road surface maintenance. technical background [0002] After a long period of use, or due to natural factors and heavy loads from accompanying vehicles, the road surface will be damaged to varying degrees, affecting or even hindering the normal operation of traffic. Almost all pavement design specifications in the world stipulate that the design life of cement pavement is 30 years, but this design life is difficult to achieve in reality, and it is very common to start maintenance within one or two years, which is common with low construction quality and overweight related. In my country, the traditional and current cement pavement maintenance method is on-site construction and repair. During the repair process, traffic on the road section needs to be blocked or semi-blocked. After the repair of the new road surface is completed, it w...
