Embodiment Construction

[0052] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific embodiments.

[0053] like Figure 1 to Figure 9 As shown, a cement pavement repair method includes the following steps:

[0054] S1: Remove road debris, and use detectors to detect voids and voids at the bottom of the road panel;

[0055] S2: According to the detection results in S1, determine the drilling position of the road surface, and mark the drilling position;

[0056] S3: According to the position marked in S2, drill holes on the road surface, and drill to the subgrade below the road surface to stop drilling;

[0057] S4: Use reaming equipment to ream the subgrade below the drilling position of the pavement panel;

[0058] S5: insert a vibrating rod into the hole formed in the step S3, and vibrate the roadbed after the hole reaming;

[0059] S6...

Abstract

The invention belongs to the technical field of road engineering, and particularly relates to a cement pavement repairing method which comprises a bag body, an extension part and a connecting part. According to the method, a repairing bag is placed in the area needing to be grouted before grouting, then grouting is conducted in the repairing bag, filled grout is wrapped by the arranged repairing bag, leakage of the grout is prevented, then the grouting pressure is guaranteed, a settled panel can be lifted, and smooth pavement repairing is guaranteed; when grouting is not carried out, the repairing bag is in a folded state, the size is small, the repairing bag is more convenient to carry, meanwhile, the bag body of the repairing bag is folded into a cylindrical shape, the folded repairing bag is more attached to a drilled hole, and then the repairing bag can enter a damaged part of a roadbed through a hole in a pavement slab more easily; and by arranging the extension part, the repair bag is prevented from being blocked in the hole of the pavement slab, the repair bag can be better unfolded during grouting, and the repairing quality is improved.

Description

technical field [0001] The invention belongs to the technical field of road engineering, in particular to a cement pavement repairing method. Background technique [0002] Cement concrete pavement is generally called rigid pavement due to its high strength. However, due to the certain flexibility of the subgrade, when the foundation at the bottom of the pavement is damaged, the upper pavement is generally not broken. The collapse of the ground foundation will cause the concrete pavement to deflect in the vertical direction, which in turn will cause the height difference between adjacent pavement slabs, which will cause bumps in the process of driving, resulting in driving comfort. reduce. [0003] In the existing treatment methods, the foundation disease at the bottom of the pavement deck is usually filled in the form of drilling grouting, and the sinking pavement deck is lifted by the pressure of grouting, thereby eliminating the gap between adjacent pavement decks. heigh...
