The swivel coupling connection of head upper end, swivel coupling communicate with the inner chamber of drilling rod and drilling tool, when drilling tool rotates with unit head and drilling rod
When carrying out drilling, stirring to original place soil, injection solidify liquid, pressure-air and cement grout, because above-mentioned solidify liquid, high pressure are empty
The inner chamber of gas and the equal hollow drill pipe of cement grout regulates and controls and is not directly injected into stage by stage one by one, therefore, is needed in work progress
The switching of gases at high pressure, solidify liquid and cement grout pipeline is carried out in unit head upper end, thus be caused to workmen
Greatly operation inconvenience, meanwhile, often there is spillage in the junction of drilling rod and drilling tool, the situation that spraying high-pressure gas is hurted sb.'s feelings, and deposits
In larger potential safety hazard.With being continuously increased for underground drilling depth, because of situations such as complex formation, soft or hard soil are mingled with,
In the rotary drilling of mixing pile drilling machine, lifting and whipping process, bottom drilling tool bears bigger drilling and stirring resistance, makes
Polish drill rod, stirring vane and drilling tool produce it is larger rock, be eccentric, hard sand gravel and debris easily cause drilling tool in soil layer
Cutter tip, the serious wear such as blade the problem of, as cutter tip cutting edge and blade wear are serious, construction operation will be influenceed
Efficiency, cause original place soil stirring in drilling cell body uneven, increase cost of equipment maintenance, also have a strong impact on the whole of improvement reinforcing body
Body intensity and barrier performance, so that the cell body quality of diaphram wall cannot be effectively ensured.
