A kind of arbitrarily angled churning technique, is mainly used in the construction of complicated geological structure, including drilling system, backstage system
System, the part of Computerized monitor system three, wherein drilling system include multifunctional drill, drilling rod, drill bit, shower nozzle, guide instrument；Backstage is
System includes automatic water mud stirring backstage, air compressor machine, high-pressure pump；Computerized monitor system.
Multifunctional drill moves to specified location, and rig is connected respectively with drilling rod, high-pressure pump, air compressor machine, and installs
Upper drill bit, mounting spray head on drill bit, high-pressure pump is connected with automatic water mud stirring backstage, and equipment is connected with the power supply at scene
Connect, main switch of closing, startup power supply, cement and water are added into automatic water mud stirring backstage by the appropriate ratio of mud, start to stir
Mix, multifunctional drill operating, the bit insertion soil body, air compressor machine supply prevents soil plug shower nozzle gas outlet, using guiding
Instrument makes drill bit creep into by planned course, reaches design path termination, starts high-pressure pump, and in soil cement mortar is injected, by injection
Stream carrys out cutting soil and cement is mixed with soil stirring, forms soil-cement body and reinforces, and drill bit is made by original design road by guide instrument
Footpath returns to ground.Computerized monitor system monitor in real time used in course of injection, checking whole work progress, and monitor drill bit is
It is no to creep into by design path, it is ensured that construction quality.
A kind of method of arbitrarily angled churning technique of employing of the present invention, comprises the following steps：
Step 1）Smooth location, accomplishes " three supplies and one leveling "；
Step 2）Measurement and positioning；
Step 3）Erection construction platform, equipment；
