Under the requirements of the three compactness standards, earth backfilling is carried out according to a specification requirement and a layer of 300-500 mm, and the earth backfilling is difficult to meet the standards regardless of mechanical operation or manual operation. In particular, in some special structure types, large-scale machinery such as a road roller and a roller machine cannot be used for construction, and only manual matching auxiliary rammers can be used for construction. However, by combining the construction experience after the backfilling of the original artificial earthwork, the compactness of most earthwork can not meet the design requirement and can only be close to the design requirement at most. Therefore, the manual rammer has low soil ramming efficiency and overlong ramming time, and influences the next procedure.
Through routine calculation, the power of a common manual tamper is less than 3000W, the effective tamping area of one tamper is about 300 multiplied by 300mm, the tamping area of one hour is 60-80 square meters, and the efficiency is realized under the condition that personnel do not stop. However, the tremor of the tamper can cause the involuntary tremor of the arms of workers, occupational diseases are easy to cause, and the workers can have a rest or change people after tamping for 15 minutes under the normal condition. Thus reducing construction efficiency and increasing personnel costs.
