Embodiment 1

[0051] Please see figure 1 and figure 2 , shows a prefabricated concrete road slab A for quick road surface repair provided by this embodiment, including a concrete slab body 1, and a steel mesh sheet is arranged inside the concrete slab body 1; Some dowel bars 2 are provided, and some dowel bars 2 are arranged at intervals, and the four sides of the concrete slab body 1 can all be provided with dowel bars 2 .

[0052] The concrete slab body 1 is provided with several slab bottom grouting holes 11, slab bottom grouting holes 12 and hoisting holes 13, wherein the slab bottom grouting holes 11 and the slab bottom grouting holes 12 are all through holes, which are connected to the concrete slab body 1. The bottom of the board is provided with a grouting diversion groove 14 communicating with the bottom grouting hole 11 and the grouting hole 12 at the bottom of the board.

[0053] Please see image 3 , the present embodiment also provides a construction method for quickly repair...

Embodiment 2

[0063] Please see Figure 6 , shows the second type of precast concrete pavement B for rapid pavement repair provided by this embodiment. Compared with Implementation 1, the difference lies in:

[0064] The side of the concrete slab body 1 in this embodiment is provided with anchoring tenons and grooves 15, and several anchoring tenons and grooves 15 are arranged at intervals, and the four sides of the concrete slab body 1 can be provided with anchoring tenons and grooves 15.

[0065] On the concrete slab body 1 corresponding to the position of the anchoring tenon and groove 15, there are tenon and groove grouting holes 16 and tenon and groove grouting holes 17, and the tenon and groove grouting holes 16 and the tenon and groove grouting holes 17 are through holes; The top surface is wider than the bottom surface.

[0066] This embodiment also provides a construction method for quickly repairing the road surface using the above-mentioned prefabricated concrete road slab B, co...

Embodiment 3

[0076] Please see Figure 8 , which shows the third precast concrete pavement slab for rapid pavement repair provided by this embodiment. Compared with Implementation 1, the difference lies in:

[0077] Please see Figure 9 The prefabricated concrete road slab C of the present embodiment is equipped with a connecting plate 6, and the groove on the side of the concrete slab body 1 is a slab groove 18, and the top surface of the slab groove 18 has an opening corresponding to the top surface of the concrete slab body 1.

[0078] Plate groove 18 depth and width are all slightly larger than connecting plate 6, and the length of plate groove 18 is slightly longer than 1 / 2 of connecting plate 6 lengths.

[0079] This embodiment also provides a construction method for quickly repairing the road surface using the above-mentioned prefabricated concrete road slab C, comprising the following steps:

[0080] Step S1: In the factory, produce precast concrete pavement C according to the sp...

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...
