Description

Technical Field

[0001] This utility model relates to the technical field of sealing cellar devices, and in particular to a structure for repairing cracks in cement concrete pavement without the need for grooving. Background Technology

[0002] China's cement concrete pavement industry has experienced rapid growth and development over the past 20 years, with current statistics showing that the total length of cement concrete pavement constructed and put into use has reached approximately 2 million kilometers. Cement concrete pavement is well-suited for heavy traffic loads and high speeds, as it has high strength, good stability, a long service life, and relatively low maintenance costs.

[0003] However, cement concrete pavements develop cracks due to factors such as the material itself, inadequate design considerations, improper construction methods or lax processes, poor operation and management, and various external forces that cause damage during use. These cracks can range from affecting the aesthetics of buildings to endangering traffic safety and shortening the pavement's service life.

[0004] Currently, the basic method for treating cracks in various engineering industries is to use a cutting machine to cut a groove of a certain width along the crack in the road surface, and then lay cement mortar in the groove. However, this method of repair is not effective, and cracks often reappear due to traffic loads or shrinkage of the adhesive, so it cannot truly repair the crack. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a non-grooving cement concrete pavement crack repair structure, which is achieved through the following technical solution:

[0006] A non-grooving cement concrete pavement crack repair structure includes a pavement crack with two ends. Each end of the pavement crack has an inclined hole. Between the two ends of the pavement crack, along the extension direction of the pavement crack, there are several equally spaced cross-cut holes. The cross-cut holes are vertically arranged. All inclined holes and cross-cut holes have countersunk holes. The pavement crack, inclined holes, and cross-cut holes are filled with grout. All inclined holes and cross-cut holes have studs. The top of the studs is not higher than the top of the countersunk holes. The grout contains granular filler.

[0007] As a preferred embodiment, the inclined hole is inclined along the direction of the crack, and the diameter of the inclined hole is greater than the widest part of the road surface crack.

[0008] As a preferred embodiment, the distance between two adjacent slit holes is 8-20cm.

[0009] As a preferred embodiment, the grouting material is epoxy resin potting compound.

[0010] As a preferred embodiment, the material of the particulate filler is corundum or yellow sand.

[0011] As a preferred embodiment, the stud is a single-sided rivet or a threaded steel bar.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the road crack repair structure of this utility model can achieve rapid repair, improve the overall stability of the road surface, effectively reduce the problem of repeated crack expansion after repair, and not only shorten the construction period, but also save costs.

[0013] It can quickly fill cracks and potholes in the road surface, preventing moisture and impurities from penetrating the road structure and thus protecting the road surface from further damage. This repair method not only restores the road surface's functionality but also effectively extends the overall service life of the road, reducing the cost of frequent road maintenance and reconstruction.

[0014] This can quickly restore road capacity, improve driving efficiency, and alleviate traffic congestion. This is of great significance for improving the overall operation of urban transportation and enhancing the travel environment for residents.

[0015] Traditional road repair methods often require extensive excavation and reconstruction, causing environmental pollution such as noise and dust, and consuming significant resources and energy. In contrast, non-grooving concrete pavement crack repair structures employ a more environmentally friendly approach, reducing environmental damage and pollution. Furthermore, due to their high repair efficiency and low cost, this technology also contributes to the sustainable development of the road maintenance industry. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0023] A groove-free cement concrete pavement crack repair structure includes a pavement crack 1, the pavement crack 1 includes two ends 2, each end 2 of the pavement crack 1 is provided with an oblique hole 3, and a plurality of equally spaced cross-cut holes 4 are provided between the two ends 2 of the pavement crack 1 along the extension direction of the pavement crack 1, the cross-cut holes 4 are vertically arranged, and both the oblique holes 3 and the cross-cut holes 4 are provided with countersunk holes 5.

[0024] The road surface cracks 1, inclined holes 3, and cross-cut holes 4 are all filled with grout 6.

[0025] Both the oblique hole 3 and the slit hole 4 are provided with studs 7, and the top of the studs 7 is not higher than the top of the countersunk hole 5.

[0026] The grouting material 6 contains granular filler 8.

[0027] Furthermore, the inclined direction of the inclined hole 3 is along the inclined direction of the road surface crack 1, and the diameter of the inclined hole 3 is greater than the widest part of the road surface crack 1.

[0028] Furthermore, the distance between two adjacent slit holes 4 is 8-20cm.

[0029] Furthermore, the grouting material 6 is made of epoxy resin potting compound.

[0030] Furthermore, the material of the particulate filler 8 is corundum or yellow sand.

[0031] Furthermore, the stud 7 is a single-sided rivet or a threaded steel bar.

[0032] In operation, this non-grooving cement concrete pavement crack repair structure involves first drilling an oblique hole 3 at each end 2 of the pavement crack 1. Several equally spaced cross-cut holes 4 are then drilled between the two ends 2 along the extension direction of the crack 1. A flexible hose is then inserted into the oblique holes 3 and cross-cut holes 4 to clean the pavement crack 1. Next, grout 6 is injected into the pavement crack 1 through the oblique holes 3 and cross-cut holes 4. Studs 7 are then driven into the oblique holes 3 and cross-cut holes 4, with the top of the studs 7 not exceeding the top of the countersunk hole 5 (i.e., the top of the studs 7 should not be higher than the pavement surface). Then, granular filler 8 is mixed into the pavement crack 1 to allow it to penetrate the grout 6. The addition of granular filler 8 increases the strength of the grout 6. After the grout 6 has solidified, it is ground smooth and flush with the pavement surface. The placement of the grout 6 allows it to penetrate the adjacent pavement structure, enhancing the firmness of the crack repair and minimizing the risk of secondary cracking. The driving in of the studs 7 increases the strength of the repair structure.

[0033] This type of road crack repair structure can achieve rapid repair, improve the overall stability of the road surface, and effectively reduce the problem of repeated crack expansion after repair. It can not only shorten the construction period, but also save costs.

[0034] It can quickly fill cracks and potholes in the road surface, preventing moisture and impurities from penetrating the road structure and thus protecting the road surface from further damage. This repair method not only restores the road surface's functionality but also effectively extends the overall service life of the road, reducing the cost of frequent road maintenance and reconstruction.

[0035] This can quickly restore road capacity, improve driving efficiency, and alleviate traffic congestion. This is of great significance for improving the overall operation of urban transportation and enhancing the travel environment for residents.

[0036] Traditional road repair methods often require extensive excavation and reconstruction, causing environmental pollution such as noise and dust, and consuming significant resources and energy. In contrast, non-grooving concrete pavement crack repair structures employ a more environmentally friendly approach, reducing environmental damage and pollution. Furthermore, due to their high repair efficiency and low cost, this technology also contributes to the sustainable development of the road maintenance industry.

[0037] The specific implementation of this utility model has been described in detail above, but it is only an example. This utility model is not limited to the specific implementation cases described above, and equivalent modifications to this utility model are also within the protection scope of this utility model.
