Embodiment Construction

[0022] A technical method for treating roadbed diseases, comprising the following steps: drilling pile holes on the roadbed; the hole positions are arranged according to plum blossom piles, and the distance between piles is 1 meter. The pile aperture is 10-20cm, and the pile aperture is determined according to the water content. Generally, the pile aperture is 15cm. The depth of the pile hole is 1-3 meters embedded in the original road surface, and generally 2-3 meters embedded in the original road surface according to the road damage situation. Tamp the bottom of the pile hole. Use the mixture to mechanically mix the uniform cement gravel, which is the C30 concrete grade, the mixture of 32.5R ordinary Portland cement and gravel, and fill the pile hole with cement and gravel; compact the cement in the pile hole during the filling process gravel. That is, every time the virtual paving is uniform in thickness of 25-30cm, use a heavy hammer weighing more than 120kg, and tamp it...

Abstract

The invention relates to a tech method for treating defect in a roadbed. Wherein, pile holes are bored on the roadbed; the holes are arranged as plum blossom piles, distance between piles is 1 m. The diameter of pile hole is 10-20 cm depending upon the water content, generally the diameter is 15 cm. The depth of pile hole is 1-3 m into the original road surface, generally the depth is 2-3 m depending upon the disease in the roadbed. The bottoms of the pile holes are tamped. Cement and gallets that are mixed evenly by a mixture machine are used, which is the mixture of C30 concrete from 32.5Rplain Portland cement and gallets; the cement and gallets are filled in the pile holes; the cement and gallets are tamped while filling, that is, 25-30 cm thick is laid evenly each time, a hammer more than 120 kg are fallen 7 times with a falling distance more than 100 cm to tamp the cement and gallets. When the filling is up to the road surface, C30 expansion concrete is used to vibrate tight the surface, then the surfaces are smoothened, holes are closed. Backfilling shall be done immediately after each hole.

Description

technical field [0001] The invention belongs to the technical protection field of road pavement, specifically the technology of repairing pavement. Background technique [0002] The main cause of roadbed diseases is that the roadbed has a high water content and a low dry density. Subgrade subsidence, muddy mud, muddying, bridge head jumping, subgrade slipping and other subgrade and pavement disease problems caused by low subgrade compaction and high water content. In the early days, solutions to road surface defects such as subsidence, muddying, and muddying were mostly adopted, such as grouting, structural layer excavation, and milling overlay. These methods have not been completely resolved due to the low degree of roadbed compaction and high water content of the roadbed. , the above-mentioned diseases will continue to occur within a certain period after treatment. In order to solve the above problems, Patent No. 98118272.0 discloses a construction method for controlling...
