Summarize
Rapid impact compaction is also called hydraulic compactor, hydraulic rapid dynamic compactor, etc. Rapid impact compaction contractors has become a new type of compaction equipment widely used in roadbed and pavement construction. It is different from traditional manual compaction and small compaction equipment. In comparison, the rapid impact compaction has the advantages of convenient transition, flexibility and efficiency, safety and environmental protection, good control performance, and high ramming energy.
Rapid impact compaction method statement
1. The rapid impact compaction contractor further reduces sand, has poor ability to remove or weaken sand in the vertical direction, and has poor virtual beam combination. The construction site strictly controls the overall quality of the roadbed project, and reinforcement is not suitable for overpressure. Overpressure can easily cause sudden pressure and damage to nearby sand. original layer structure.
2. The original pavement reinforcement effect is remarkable, and marketing, promotion and application should be carried out; after the rapid impact compaction machine subgrade project is filled with an aspect ratio of 1m, point compaction can be selected instead of impact rolling; after the subgrade project is filled with an aspect ratio of 8m, full compaction is adopted Instead of static piles.
3. In the whole process of roadbed engineering reinforcement, if some foundations settle too much, reinforcement measures should be taken according to the specific situation, that is, 3-6 hammers should be filled in the middle of the four ramming points of the rapid impact compaction equipmentto improve the actual effect of the overall reinforcement. It is also beneficial to the leveling of the overall excavation working surface.
4. For some filling subgrade edges with narrow excavation face, the flexibility of rapid impact compactor should be fully utilized. The fast and small footprint further enhances the practical effect of filling the edge of the roadbed and chicken feet.
5. In the three-back reinforcement work, one side should be compacted according to the standard from both sides to the middle; the culvert backfill must ensure that the matching layers on both sides of the hole body are reinforced; offset monitoring observation points and real-time monitoring should be set before reinforcement system. If it is found that the asymmetric pressure throughout the working process changes the structure, the ramming potential should be reduced and the ramming frequency of the rapid impact compactor should be increased.
The characteristics of rapid impact compactor
1. The transition is convenient, flexible and efficient, and the control performance is good. The rapid impact compaction machine is installed on the excavator or loader of the equipment. The process of transition and construction is very flexible, and the operation is also very simple, which greatly improves the construction efficiency and reduces the construction cost.
2. Safety and environmental protection, eliminate noise. The hammer body of the rapid impact compaction equipment is placed in the skin, which can greatly reduce the accidental injury to people, and at the same time play a very large role in eliminating noise, thus achieving the effects of safety and low noise.
3. The impact on adjacent structures is far less than other compaction methods. During the construction of the rapid impact compactor, the force propagation direction is mainly vertical downward, and the impact on other adjacent structures is small. It can be constructed close to the bridge abutment, retaining wall and other structures, which is safe and reliable.
4. High speed and high efficiency, cost saving. The ramming frequency of the rapid impact compaction produced by Hangshen is 30-80 times per minute, which significantly improves the work efficiency, and the ramming frequency occupies the front row in the same industry.
5. Wide range of uses, suitable for various fillers. The rapid impact compactor is not sensitive to the cost and moisture content of the filler, and has obvious compaction effect.
6. Independent research and development and production, continuous product innovation. HC series rapid impact compactor was invented and named by Cao Bin, chief engineer of our factory in 2002. Our factory has been continuously updated to the sixth generation, and has passed the inspection of the Xi'an Road Construction Machinery Inspection Center of the Ministry of Transport.
Construction effect of rapid impact compaction
Rapid impact compaction plays an important role in eliminating the differences in construction progress and process conditions of different professional construction teams, as well as the differential settlement of the foundation caused by factors such as rushing the construction period and rushing into the schedule. The construction effect of rapid impact compaction is mainly reflected in the fact that it can eliminate or weaken the inherent defects and man-made defects of local road sections such as the layered roadbed, the back of the abutment, the half fill and half excavation, the local high fill, the junction of old and new roads, etc., which may occur. during basic use. Rapid impact compactor have very flexible applicability and effectiveness in solving the problem of low quality of backfill on highway abutments and bridge and culvert sides. It can flexibly and flexibly compact different compaction operation positions accurately and quickly, or compact the operation area in a single point or continuously.
Rapid impact compaction can be used with excavators and loaders. It has the functions of convenient transition, flexibility and efficiency. Its simple operation method has been liked by customers. Compared with traditional manual rammers and dynamic rammers, rapid impact compaction are convenient and flexible. , and economical, it performs very well in the compaction of foundations and roadbeds. Hangshen is a manufacturer of rapid impact compaction. It has strong production strength, independent research and development and innovation capabilities, reliable product quality, and perfect pre-sales and after-sales services.
