Description

Technical Field

[0001] The utility model belongs to the technical field of water-stabilized maintenance, and in particular relates to a cement-stabilized crushed stone base maintenance device. Background Art

[0002] Maintenance regulations for cement stabilized gravel base: 1. After a section of the working surface is rolled and passed the compaction test, it is immediately covered with a blanket and pressed with cement blocks to prevent it from being blown away by the wind. After the cement of the water-stabilizing layer is finally set (2-3 hours after rolling), it is then exposed to water and moistened. At the same time, all traffic is closed. 2. During the curing period, people are often sent to check the watering and blanket coverage. For places that are not covered in place, the surface of the mixture should be immediately sprinkled with water and then covered again. Avoid long-term water loss or alternating dryness and wetness on the surface of the water-stabilizing base to ensure the strength of the structural layer and reduce the possibility of shrinkage cracks. The curing period is not less than 7 days. 3. After the construction is completed every day, the front-field construction worker of the water-stabilizing will give instructions to the person in charge of the maintenance team. The instructions include specific construction sections and construction dates. 4. The maintenance period after the completion of the water-stabilizing construction is 7 days. The sprinkler truck will sprinkle water at least 7 times a day in the first 3 days of maintenance, and the water will be exposed to water at least 4 times a day in the last three days. The water must be thoroughly watered by the water truck.

[0003] In the existing cement-stabilized gravel base maintenance devices, such as the cement-stabilized gravel base maintenance device disclosed in Publication No. CN211472081U and the cement-stabilized gravel base maintenance device disclosed in Publication No. CN216891890U, plastic film is used instead of blanket covering in their technical solutions. The disadvantage is that the plastic film is not water-permeable and water-infiltrative, and the cement-stabilized gravel base needs to be maintained for seven days, and watering is required many times during the period. The use of plastic film seriously affects the watering operation. The plastic film needs to be uncovered each time for the watering operation, and then the plastic film needs to be re-laid. The operation is frequent, which affects the construction progress. In addition, the plastic film is a non-recyclable item, which also has a certain impact on environmental protection.

Several blankets are arranged in sequence along the length direction of the cement-stabilized gravel base, and a blanket with good water permeability is used to replace the existing plastic film, which does not affect the watering operation during maintenance.
