The first RIC in China is produced in our factory, and we have excellent R&D and production capabilities.The rapid impact compaction can be directly installed on the forklift or excavator and is flexible and maneuverable, and the edge position does not need to be independently selected by small and medium-sized compaction tools; the depth of effect is large, and it can backfill 1-4m at one time, further improving the high efficiency of engineering construction; reducing the reduction of small and medium-sized The capital investment of tamping machinery and equipment and human resources reduces the utilization rate of the tamping machinery and equipment, and the construction cost is greatly reduced; it has a mild effect, and has a strong and well-proportioned working ability. A relatively uniform degree of compaction is obtained in a large depth range.
Application field of rapid impact compactor
The construction technology of rapid impact compaction equipment is suitable for backfilling of cover plate culverts, basic solutions for small areas and backfilling of deep pipe trenches.
The basic principle of rapid impact compaction machine processing technology
①The rapid impact compaction equipment is assembled on a forklift or excavator, and it is flexible and flexible; ②The rapid impact compaction does not need small and medium-sized compaction tools to solve the edge; 4. The single-machine version of the rapid impact compaction can be used for tamping work, reducing the expenditure of machinery and equipment and the cyclic backfilling work of tamping machinery and equipment; 5. The rammer raised to a certain height-to-width ratio accelerates the fall under the action of the force. , and repeatedly move under the effect of the hydraulic transmission system, quickly hit the tamper plate with shock-absorbing rubber pad and negative pressure on the road surface, and then ram the road surface according to the tamper plate.
Construction effect of backfilling on the back of rapid impact compaction equipment
(1) The rapid impact compaction is used for ribbing of the subgrade at the back of the platform, which can improve the compactness of the subgrade and reduce the settlement of the subgrade. The construction technology clearly proposed in the experiment is more effective, and the selected filler is effective.
(2) The large dynamic stress on the roadbed caused by the rapid impact compaction during operation is affected by the compaction potential, the relative height of the compacted subgrade and the elastic modulus of the subgrade, and the compaction potential is the key influencing factor. The dynamic stress caused by the rapid impact compaction equipment increases with the increase of the tamping frequency, slightly increases with the increase of the relative height of the tamped roadbed, and increases with the increase of the tamping potential. The dynamic stress caused by the first, second and third gears The trend analysis is basically the same.
(3) The longitudinal dynamic stress caused by the rapid impact compactor decreases rapidly with the increase of the depth, and the critical damage depth of stress is in the middle of 20~25m. The total hazard width of the tamper at a depth of 25m is approximately 15m.
(4) The dynamic stress caused by the vibratory roller at the same depth of the roadbed is about 16.0%~20.0% of the tamper, and the dynamic stress caused by the small and medium-sized rammer is about 31%~3.9% of the tamper.
(5) After the subgrade is compacted, the key to increase the bearing capacity is within the depth of 25m, and the average bearing capacity of the second and third gear areas within the range of 25m basically increases by about 20kPa and 30kPa respectively. The higher the tamped subgrade, the smaller the increase in bearing capacity basically.
(6) Subgrade settlement increases with the increase of compaction frequency, and its annual growth rate decreases with the increase of compaction frequency. The subsidence of the foundation gradually decreases with the depth, and the deformation amount mainly appears in the depth range of 15m.
(7) The density of the subgrade surface increases with the increase of the frequency of compaction. The subgrade in the three intervals has 16 times and 12 times of energy respectively in the second and third grades, and the density increases by 2.4%, 19%, 21% and 35% respectively. , 27%, 25%. The change of compactness along the depth mainly occurs in the upper and lower range of 2m.
(8) When the rapid impact compaction equipment is tamping, the concrete on the back of the platform mainly produces elastic deformation, and the larger strain force increases slightly with the increase of the tamping frequency, but it does not exceed 10.
