According to the requirements of the drawings, the surface of the foundation roadbed of the rapid impact compactor needs to be leveled to ensure that the roadbed of the rapid impact compaction machine is evenly impacted to achieve the due impact rolling effect. During the compaction process, it is necessary to clearly mark the obstacles on the ground, such as underground structures, pipelines, cables and other facilities within the construction scope. During the compaction process, it is necessary to clearly mark the obstacles on the ground, such as underground structures, pipelines, cables and other facilities within the construction scope.
Before construction, all relevant information on the site should be collected, the construction should be planned according to the requirements of the construction period, construction conditions and climatic conditions, and the number of rapid impact compactors and the number of construction operations should be reasonably arranged. Complete the construction work in accordance with the requirements of the technical specifications for highway subgrade construction, complete the re-measurement of the conductor, center line, leveling point, cross-section inspection and supplementary measurement, and increase the leveling point, etc., and determine the embankment toe and slope protection according to the requirements of the design documents.
The tamping frequency of rapid impact compaction machine is generally about 30-80 times per minute. The tamping depth and tamping frequency produced by Hengda Machinery can be controlled by the controller. However, in actual engineering, it is affected by many aspects, which will affect the tamping frequency and tamping depth. At the same time, there are many external factors that affect the construction quality, including five aspects: materials, machinery, methods, environment, and personnel.
As far as rapid impact compaction machines are concerned, although operators and mechanical equipment are easy to fix, once the construction environment changes, it may be affected and restricted by external factors such as the properties of basic materials, water content, and road construction requirements, and it may be necessary to change the construction method or construction. craft. Of course, the construction party or the designer can also summarize and accumulate more construction experience.
The working principle of the rapid impact compaction is to use the hydraulic cylinder to send the tamper to a certain height, and then quickly release it from a certain height, and accelerate downward under the combined action of gravity and hydraulic accumulator. The rammer accelerates backward and hits the tamper plate with a special cushion, the function of which is to maximize the transmission of the vertical impact force to the ground. At the same time, the rammer moves up and down rapidly under the action of the hydraulic device. The rapid impact compaction is pulled by the loader or excavator supporting device to achieve the purpose of quickly changing the compaction position. The three-back backfill and other subgrade joints are compacted, the overall construction quality of the subgrade is improved, the post-construction settlement of the joint is effectively reduced, and the domestic large-scale compaction is made up. The quality defect that the machine cannot be compacted in place.
