Rapid impact compaction is also known as hydraulic impact rammer, rapid impact compaction, etc., rapid impact compaction can be equipped with excavator, loader application, HC series products hydraulic impact ramming completion system automatic operation, hydraulic speed and other roles, compaction compressive strength multi-level adjustable, the impact depth can be achieved 1 ~ 10m.
1.Construction technical characteristics. (1) The rapid impact compaction is assembled on the forklift or excavator flexibly and maneuverable, and the edge position does not need to be solved by independently selecting small and medium-sized tamping tools; (2) The effect is deep, and it can be backfilled by 1 to 4m at one time, and the high efficiency of engineering construction is further improved; (3) Reduce the expenditure of small and medium-sized compaction machinery and equipment and labor costs, reduce the utilization rate of compaction machinery and equipment, and greatly reduce construction costs; (4) With mild efficacy, strong and symmetrical around the ability.
2.Application field. This construction method applies to the backfilling of the dark plate culvert, the small-scale foundation treatment and the backfilling of the deep pipe ditch.
3.Process principle. (1) The rapid impact compaction is assembled on the forklift or excavator, which is flexible and flexible; (2) rapid impact compaction tamping does not use small and medium-sized tamping tools to solve the edge; (3) The effect of the tamping machine is deep, and it can be backfilled for 1~4m depth at a time; (4) The rapid impact compaction can carry out the tamping work, reduce the expenditure of small machines and the backfilling work of compaction machinery and equipment; (5) Rammer hammer raised to a certain height and width ratio in gravity
Rapid impact compaction is a new type of hydraulic compaction machinery and equipment widely used in the current stage of the tamping engineering project, which can support the application of forklifts, excavators, loaders and other applications, the installation method is simple, the use is more convenient, and it has the advantages of faster conversion site and higher work efficiency.
1. At the cost level, with the continuous increase in the cost of fuel and manpower, the price and cost of the pneumatic rammer or tamping machine that have been used for a long time are getting higher and higher. Although the price of the rapid impact compaction is still relatively expensive, for new projects with many structures and a very large backfill, the corresponding cost of applying the rapid impact compaction is better.
2. At the construction period level, the owners of new projects now have more stringent regulations on the construction period of the project, and the construction of the three-back backfill project is the main factor that hinders the progress of structural engineering construction and subgrade filling. The reasonable compaction depth of the rapid impact compaction is 2m-2.5m, which can reduce the frequency of backfilling and compaction, the social benefits are significant, and the construction period can not only control the cost, accelerate the overall progress of the project, but also reduce the cost of industrial equipment and various management methods for new projects.
3.In terms of quality, the quality management of rapid impact compaction is simpler than that of the old tamping process. The rapid impact compaction can meet the technical standards of the newly created and expanded highway subgrade reinforcement solution, providing an efficient compaction method for unique roads such as drainage engineering backfilling, tunnel substrate solution, rock filling subgrade, filling and digging joint part, new and old subgrade engineering joint part "chicken claw irrigation canal", especially suitable for unique roads with narrow working surfaces or common compaction machines.
