1.Compaction of granular soil in a narrow site.
2. Backfill soil compaction for roadside stones, concrete structures, sidewalk drainage ditches, gas and sewage treatment projects.
3. Leveling and compaction of sand, gravel, soil and asphalt surface.
4. The surface of concrete is grouted and leveled.Vibration tamping machine compacts the pipe backfill Pipe top backfill.The compactness of the pipe top backfill is less than that of the pipe side backfill, so under the load, the soil at the top of the pipe settles more than the soil on the pipe side, causing relative displacement between the two, which can produce a kind of prevention The upward shear force caused by the sinking of the soil on the top of the pipe reduces the top load, reduces the pressure of the soil on the pipe, and thereby reduces the deformation value of the closed body. Of course, the soil near the road surface should still be constructed in accordance with the requirements of the roadbed to achieve road construction quality.Here we first use graded gravel to fill the top of the pipe, and then backfill 50cm on the top of the pipe with clay, hand-push the plate compactor, use a vibratory rammer, the plate compactor company, and then use an excavator to dig the trench to the road roller Wide, use an excavator to backfill the clay road roller and compact it in place. Pay attention to the geotechnical test.
