How to use rapid impact compactor for loader

1. Do a good job of preparation before construction: choose a compacted road, and carry out the leveling of the site before hydraulic press compaction according to the new project prepared before construction; make safety technical disclosures to the employees, so that they can master the physical properties; configure experimental equipment and professional The technicians have passed the professional training and are familiar with the inspection and processing technology of roadbed engineering; if the tamping machine is in normal trial operation, inspection, inspection and maintenance shall be carried out on time.

2. Carry out edge solutions. When backfilling and compacting at the edge of the building, firstly backfill and compact the area around the building in layers. The thickness of each layer of loose fill is 0.5~-0.8m, and the thickness of the backfill is not less than 2.0m across the top of the structure. Carry out consolidation work.

3. Backfill a layer of backfill raw materials according to the overall planning of the design drawings, the backfill depth is 1~4m, and the surface is flat.

4. The tamping is ready for the construction of the project. The tamping solution is carried out by using the red plum blossom tamping method. The hydraulic cylinder is used to raise the rammer to a certain relative height and it has been released. Accelerate down and land, and after falling, the impact negative pressure will be on the rammer foot with shock-absorbing pad on the road surface, and then ram the road surface through the rammer foot. Because the effect of the rammer on the road surface is implemented by the negative pressure on the road surface with the tamping foot with shock-absorbing pad, and under the actual effect of maintaining the hydraulic airbag shock-absorbing equipment, compared with the traditional dynamic ramming foundation, its effect is stronger. The highest value is small, the actual effect time is long, the actual effect is mild, it is not easy to cut and fill the prominent characteristics, and it has the functions of anti-dust control and anti-splash. Compared with traditional vibratory rollers and small and medium-sized compaction machines, its surrounding work ability is strong and well-proportioned, and it is not easy to form surface hard blocks in the foundation solution, and a relatively well-proportioned compaction degree can be obtained in a large depth range.

5. The remaining step is to check the compactness. Check settlement and compactness.

1. Impact compaction has a large impact depth;

Rapid impact compactor can significantly change the structure of sandy soil, preload the subgrade soil again, reduce the expansion of basic raw materials, improve its anti-vaporization working ability, and remove collapsibility, etc., thereby improving the uniformity of soil quality and reducing the possibility of future The material shows that the reasonable hazard depth of rapid impact compaction machine is usually 4 meters long. With the expansion of ramming energy, the reasonable solution depth increases, and the hazard depth can reach 10 meters long.

2. Two compaction methods of high amplitude and high frequency can be completed

The impact tamping of rapid impact compaction machine has a large depth of damage due to its tamping effect of large vibration amplitude. Usually, rapid impact compaction machines are equipped with three stroke arrangement gears, large, medium and small. When the rapid impact compaction equipment is used in the construction of the car gear project, it has the The higher the working frequency of compaction, the fast speed of the rapid impact compactor refers to the "high frequency", and the high frequency is also beneficial to the foundation compaction.

3. It can complete large tonnage of narrow and small parts

Compaction Before the popularization of rapid impact compactors, the foundation compaction of some narrow processes usually only uses small and medium compaction machinery such as vibration compactors and frog compactors, or even manual compaction. Tonnage compaction, large amplitude compaction and high frequency compaction can be switched anytime and anywhere to meet different compaction requirements.

4. The post-construction settlement of the foundation can be removed early

The rapid impact compactor is the same as the Hongmeihua impact roller vibratory roller. The actual effect of the project construction is mainly reflected in the early removal or weakening of the subgrade compaction project, cover plate culvert back, half filling and half excavation, part of the high filling subgrade and new and old roads. The inherent problems and artificial shortcomings of some roads such as the junctions will be cleared in advance of the post-construction settlement that may occur during the foundation application process.

Rapid impact compaction machine has obvious effect on clearing the differential settlement of the foundation caused by the difference of the project progress and processing technology standards of different professional engineering construction teams, as well as other reasons such as rushing the construction period and rushing the progress of bridge piers and roadbed projects.
