Navigation channel drilling on waterways method.
Background technology
Probing is from earth's surface to underground drilling and forming hole, so as to reach the engineering construction measure of preset requirement with plant.
Drilling method of the prior art is as follows：
The patent application of Application No. 02807756.3 discloses a kind of drilling method carried out with a drilling equipment, and this sets
A drilling rig is had, the device includes a case member and a drilling assembly, there is the of drill centers in its drill head
One boring tool and the flushing to the second boring tool of case member centre bore reaming and for rinsing caused scrap
Stream construction.First boring tool is connected in power transmission at least under drilling situation, and in order that the instrument moves from drilling
Go out, an extensible construction such as bayonet coupling etc couples with the second boring tool.In the scouring media that center is completed
Internal drilling of the feed flow by belonging to the first frame parts portion of the first boring tool is transported to its outer peripheral edge, and in order to complete
The inverse circulation of scouring media is called, the return stream of scouring media is conveyed from the drilling surface of the first frame parts by internal drilling therein
Into the space between the first frame parts and case member.
The patent application of Application No. 201380023210.6 discloses a kind of method using drill string drilling subterranean well,
Comprise the following steps：A, drilling fluid is injected into well by drill string, and by annular space return line from the ring around drill string
The drilling fluid is removed in shape space (annular space)；B, the pressure oscillation of the fluid in annular space is made；C, vibrated for each Fluid pressure
Determine well storage volume and well packing coefficient；D, store volume using well and well packing coefficient is determined in the pressure
Gas volume fractions and liquid volume ratio during forced oscillation in annular space.
Drilling is protected using borehole casing in the prior art, being generally arranged at drill mouth prevents aperture from collapsing, can also be
Some supporting section plays a supportive role under hole.When navigation channel drilling on waterways runs into solution cavity in deeper stratum, usual method is colored

Step 2：In the position of i-th layer of solution cavity, the drilling rod of drilling tool is drilled into i-th layer of solution cavity to the bottom plate position of i-th layer of solution cavity,
Wherein i is the natural number more than or equal to 1；
Step 3：Drilling rod is withdrawn, the solution cavity as described in claim 1-5 any one is installed in the drilling rod lower end of drilling tool and protected
Device, the solution cavity is sent at i-th layer of solution cavity with protector, entered with described sleeve pipe (1) completely through i-th layer of solution cavity
Row setting is defined；
Step 4：Rig is rotated backward so that solution cavity connects disk (4) with the casing joint (2) in protector and sleeve pipe departs from, is made
Obtain sleeve pipe (1), casing joint (2) and sleeve pipe cutting shoe (3) to stay at i-th layer of solution cavity, complete the protection of i-th layer of solution cavity；By band
There is sleeve pipe to connect the drilling rod of disk (4) to withdraw, remove after sleeve pipe connects disk (4) and continue to drill；
Step 5：In i+1 layer solution cavity position, repeat step two to step 4, and the solution cavity used at i+1 layer solution cavity is used and prevented
The model of solution cavity protector is small used at than i-th layer solution cavity of the model of protection unit；When without solution cavity and to reach probing deep
When degree requires, probing finishes.
