Description
Technical field
The utility model belongs to a kind of drilling tool, more particularly to a kind of to add for diaphram wall construction, soft soil foundation improvement
Solid mixing pile drilling machine combination drill tool.
Background technology
With the rapid development of the national economy, Construction of Urban Rail Traffic, underground are being accelerated in China main cities now
The urban infrastructures such as utilization, the isolation of rubbish heap buried place and the river dyke foundation stabilization in space, wherein, often should
With a kind of shaped steel cement-soil composite mixing pile construction technology（That is SMW construction of diaphragm walls technique）, driven and connected using power head
The hollow drill pipe of its output shaft and hollow drilling tool are connected on, drilling tool carries out drilling using anterior cutter hub after rotating and stirring is constructed, such as
During construction of diaphragm wall, drilling tool one side drilling stirring, while gases at high pressure, solidify liquid are sprayed into underground, to accelerate
The flowing and stirring of underground, certain ratio is sprayed into after drilling and agitating procedure are completed by hollow drill pipe and hollow drilling tool
The cement mortar of example, finally extracts whole drilling rods and drilling tool, removes drilling machine insertion shaped steel, contains cement in diaphram wall groove body
