Description
Technical Field
The utility model relates to a crowded close stake hole of lime soil, in particular to a whitewashing dado mechanism in crowded close stake hole of lime soil that high backfill soil field set up on the ground.
Background
Some high-rise buildings are built on a high-backfill miscellaneous fill field, the soil permeability of the high-backfill fill field is good, the soil is loose soil, the water absorption saturation is strong, and the water in the soil is non-pressure saturated water; under the geological condition, the foundation of the high-rise building has two construction selection modes: the first is a method of setting a bored concrete pile, the depth of the bored concrete pile must penetrate high backfill miscellaneous fill to enter a rock stratum, and the depth of some high backfill soils reaches more than 30 meters, so that the pile length of the bored concrete pile needs to reach deeper depth, and the construction method is too high in cost; the second kind is for setting up intensive lime-soil compaction stake mode, with the extrusion of the soft foundation soil layer around the stake hole and consolidate, forms more firm lime-soil compaction stake hole, the execution process of lime-soil compaction stake is: firstly, spirally drilling a compaction pile hole in a backfill soil layer through an environment-friendly compaction pile machine, and filling lime soil with a designed proportion into the pile hole and tamping to form a lime soil compaction pile in the drilled compaction pile hole; in the process, water in the pile hole needs to be pumped out, the wall of the pile hole does not collapse, then the lime soil can be filled, and the problem to be solved in field construction is that the collapse phenomenon of the spirally drilled compaction pile hole does not occur due to the fact that the depth of the compaction pile hole is dozens of meters.
Disclosure of Invention
The utility model provides a high shotcrete dado mechanism in crowded close stake hole of lime soil that backfills soil field set up has solved crowded close stake hole and has taken place the technical problem who collapses easily.
The utility model discloses a solve above technical problem through following technical scheme:
a guniting wall protection mechanism for an ash soil compaction pile hole arranged on a high backfill soil field ground comprises the high backfill soil field ground, the compaction pile hole is arranged on the high backfill soil field ground, a winch frame is arranged on a pile opening of the compaction pile hole, a winch is arranged on the winch frame, a support ring is hung at the end part of a lifting rope of the winch, a rotary guniting machine is hung on the support ring, a rotary nozzle is arranged at the lower end of the rotary guniting machine, the support ring and the rotary guniting machine are arranged in the compaction pile hole, a slurry storage vehicle is arranged on the high backfill soil field ground outside the winch frame, and a slurry conveying pipe is arranged between the slurry storage vehicle and the rotary guniting machine.
The water pumping pipe is arranged in the pile hole of the compaction pile, the lower end of the water pumping pipe is connected with a filter screen, the filter screen is arranged at the bottom of the pile hole of the compaction pile, the upper end of the water pumping pipe is connected with a water pumping pump, and the water pumping pump is arranged on the ground of a high backfill soil place outside the winch frame.
The utility model discloses a to the dado of compaction stake hole inside wall, equipment operation is simple and convenient, the darker compaction stake of specially adapted degree of depth.
