Problems solved by technology

When the slab breaks on the road surface, the road is already open for traffic. If the use of the road is suspended for a long time, it will not only affect people's normal travel, but also cause traffic pressure on other roads and cause unnecessary accidents.

Embodiment 1

[0031] Such as figure 1 and image 3 As shown, the present embodiment provides a road repair method, the specific steps are as follows:

[0032] S10: Excavate on the transverse fractured road surface, remove the fractured part according to the excavation situation, the depth of the excavation is greater than the depth of the fracture, and the notch of the excavation is regular to facilitate the cutting of the steel mesh;

[0033] S20: cleaning and trimming the four walls of the notch, and chiseling the joint parts of the notch;

[0034] S30: Due to the wide and shallow notch of the transversely fractured pavement, when installing the dowel bars, select 5 points with the same average distance to install the dowel bars, try to drive the dowel bars horizontally into the wall of the notch, and each dowel bar in the same horizontal plane;

[0035] S40: Cut the reinforcement mesh according to the shape of the notch so that it can be put into the notch evenly, place the reinforcemen...

Embodiment 2

[0039] Such as figure 1 , figure 2 and image 3 As shown, the present embodiment provides a road repair method, the specific steps are as follows:

[0040] S10: Excavate on the longitudinally fractured road surface, remove the fractured part according to the excavation situation, the depth of excavation is greater than the depth of the fracture, and the excavated notch is regular to facilitate the cutting of the steel mesh;

[0041] S20: cleaning and trimming the four walls of the notch, and chiseling the joint parts of the notch;

[0042] S30: Due to the small and deep notch of the longitudinally fractured pavement, when installing the dowel bars, select three points with the same average distance to install the dowel bars, try to drive the dowel bars horizontally into the wall of the notch, and each dowel bar in the same horizontal plane;

[0043] S40: Cut the reinforcement mesh according to the shape of the notch so that it can be placed in the notch flatly, place the ...

Embodiment 3

[0051] Such as figure 1 , figure 2 and image 3 As shown, the present embodiment provides a road repair method, the specific steps are as follows:

[0052] S10: Excavate on the longitudinally fractured road surface. According to the excavation situation, remove the fractured part. The depth of excavation is greater than the depth of the fracture. Since the depth of the longitudinal fracture is deep, the vertical notch is not conducive to the installation of the dowel bar , trim the excavated notches into pit rows;

[0053] S20: cleaning and trimming the four walls of the notch, and chiseling the joint parts of the notch;

[0054] S30: According to the size of each cross-section of the pit-shaped notch, select the number of dowel bars to install, 3 on the first layer, 5 on the second layer, and 7 on the third layer, and choose points with the same average distance to install the force transmission Rod, drive the dowel rod horizontally into the notch wall as far as possible...

Abstract

The invention provides a pavement repairing method. In order to solve the problem that the existing road surface repairing time is long, the invention provides the road surface repairing method which comprises the steps of digging a road surface, cleaning a notch, mounting a dowel bar, laying a strength structure, pouring concrete and the like, and ECO modified polyurethane concrete is used, so that the concrete curing time in repairing construction is greatly shortened; and the ECO modified polyurethane concrete has high strength and waterproofness, so that good connection between the repair structure and the original road surface is facilitated, and the driving danger caused by damage of the pavement structure is effectively prevented. Different road repair designs can be carried out according to different road fracture conditions, and quick repair of pavements with various fracture depths and widths is achieved by controlling the number of layers of the reinforcing meshes.

Description

technical field [0001] The invention relates to the field of road surface paving, in particular to a road surface repair method. Background technique [0002] When designing the pavement, the service life of the pavement will be required according to the specified vehicle load and the predicted traffic flow. However, after opening to traffic, there will be phenomena such as overloading and speeding during the actual use of the road surface, and the number of passing vehicles will be much greater than the predicted number. These factors will have a negative impact on the road surface. Among them, the most common and the greatest impact on driving safety is the fracture of the pavement slab caused by the above factors. When the pavement breaks, the road is already open for traffic. If the road is suspended for a long time, it will not only affect people's normal travel, but also cause traffic pressure on other roads and cause unnecessary accidents. Contents of the invention...
