Example Embodiment

[0050] Example 1:

[0051] see figure 1 and figure 2 , shows a prefabricated concrete pavement A for rapid road repair provided by this embodiment, including a concrete plate body 1, and the concrete plate body 1 is provided with reinforced mesh; A plurality of dowel rods 2 are provided, and the plurality of dowel rods 2 are arranged at intervals.

[0052] The concrete slab body 1 is provided with a number of bottom grouting holes 11 , bottom grouting holes 12 and hoisting holes 13 , wherein the bottom grouting holes 11 and the bottom grouting holes 12 are all through holes, which are located in the concrete slab body 1 . The bottom is provided with a grouting guide groove 14 communicating with the bottom grouting hole 11 and the bottom grouting hole 12.

[0053] see image 3 , the present embodiment also provides a construction method for quickly repairing the road surface by applying the above-mentioned precast concrete road panel A, comprising the following steps:

Abstract

The invention provides a precast concrete pavement slab structure for quick repair of a pavement and a construction method of the precast concrete pavement slab structure. A reinforcing mesh is arranged in a concrete slab body of the concrete pavement slab; the side face of the concrete slab body is provided with a protruding rod piece or provided with an open groove. The concrete slab body is provided with a slab bottom grouting hole, a slab bottom grout outlet hole and a hoisting hole, and the bottom of the concrete slab body is provided with a grouting diversion trench. The original concrete pavement is provided with corresponding rod pieces or grooves, grouting is conducted in the grooves to achieve connection between the prefabricated concrete pavement slab and the original concrete pavement, and grouting is conducted to the slab bottom of the prefabricated concrete pavement slab to achieve tight attachment between the prefabricated concrete pavement slab and the base layer, so that connection between the prefabricated concrete pavement slab and the original pavement and connection between the prefabricated concrete pavement slab and the base layer are guaranteed. The problems that in the prior art, a cast-in-place concrete pavement repairing mode and an original concrete pavement are poor in connecting effect and durability are solved. And compared with a cast-in-place concrete mode, the construction time is short, the hardening speed is high, and therefore rapid traffic recovery can be achieved.

Description

technical field [0001] The invention belongs to the technical field of assembled prefabricated concrete pavement, and in particular relates to a prefabricated concrete pavement structure and a construction method for rapid pavement repair. Background technique [0002] At present, many concrete pavement projects such as municipal projects, bridges, and airport roads in our country are damaged. After the damage, it is usually repaired by cast-in-place concrete. The hardening time of cast-in-place concrete is long, which greatly affects the time to restore traffic. It is difficult to maintain the cast-in-place concrete in such an environment, and the connection effect between the repaired concrete pavement and the original concrete pavement is poor, there are many cracks, poor durability, and a short service life. [0003] The production and maintenance of precast concrete pavement are all carried out in the factory, and its quality is obviously better than that of cast-in-pla...
