Description
Technical field
The invention belongs to geotechnical engineering investigation field, more particularly to a kind of well head core is held and cutting device and its use
Method.
Background technology
In geotechnical engineering investigation, to obtain the distribution of strata situation in place to be reconnoitred, need to bore at the exploratory spot of arrangement
It visits coring and is edited and recorded.During boring coring, after drill bit is drilled into designated depth, operating personnel rise and unload drilling rod, by core
Pipe is promoted to outer wellhead, unloads core barrel, water pipe will be connected at the top of core barrel, is rushed the core in core barrel using the pressure of water
Go out to ground on the waterproof cloth or plank being laid with.After core is gone out completely, operating personnel are blocked core using scoop, by core
It is carried in rock core box, core is put by the sequencing for going out core barrel.Personnel are edited and recorded to name and sentence to soil layer according to core
Then round trip label and geotechnical stratified label according to core putting in rock core box, are attached to by disconnected geotechnical stratified situation in time
On core, and record to live boring log table.
But disadvantage there are many this processes is found in real work：
1, during core is gone out, the waterproof cloth or hardwood plate friction that core is laid with ground cause core distortion even
Bending is difficult to distinguish the upper and lower relation of the core after bending sometimes；
2, after core is gone out, operating personnel block core with scoop, and are carried in rock core box, and rock core box length is 1m,
During this, the estimation of operating personnel is leaned in the position blocked entirely, and core usually less than 1m or is more than 1m, when this will cause to edit and record
The error of strata division depth；
3, the core after manual intercept is placed on ground, and operating personnel is needed to bend over to be carried to rock core box, and working strength is larger,
The problem of core fractures is likely to occur in handling process.
Invention content
To solve the above-mentioned problems, the present invention propose a kind of well head core hold with cutting device and its application method,
It can effectively ensure that the integrated degree of core, improve core quality and layering precision.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of well head core is held and cutting device, including inner sleeve, outer tube, one end of the inner sleeve and housing
One end of pipe connects together；In inner sleeve, outer tube junction, the internal diameter of the outer tube is more than the outer diameter of inner sleeve, because
This, after core barrel is brought up, drill bit position can be stuck in inner sleeve, outer tube junction；And after the other end of inner sleeve is equipped with
Baffle；
Water fender is installed on the outer tube close to inner sleeve, outer tube junction, the water fender passes through hinge
It is connected on outer tube, water fender can open and close；
It is equipped with the guide rail parallel with its axis in the outside of the inner sleeve, being equipped on the guide rail can be along it
The sliding block to slidably reciprocate is equipped with coupled cutter on the sliding block, and cutter is the semicircle stalloy for having blade, directly
Diameter diameter is slightly less than inner sleeve bore, and the cutter can be with free-open-close relative to inner sleeve.
Preferably, diameter of the housing bore slightly larger than drill bit on core barrel.
Preferably, the inner sleeve bore is slightly larger than core diameter.
Preferably, the inner sleeve, outer tube cross section be semicircle or fan-shaped.
Preferably, it is equipped with fore-stock in the bottom of the outer tube, after-poppet is equipped in the bottom of the inner sleeve.
Preferably, fore-stock, after-poppet height be 1.2m or so.
Preferably, the rear baffle is equipped with notch.
Preferably, the guide rail is equipped with scale, and the sliding block is equipped with fastening bolt, for fixing sliding block.
Further, the present invention also provides a kind of well head cores to hold the application method with cutting device, specific as follows：
In use, core barrel is proposed well head, place it on outer tube, along outer tube forward slip, through outer tube with
Inner sleeve junction resists, and closes water fender；
The drilling rod being connected with core barrel is unloaded, water pipe is connected with core barrel, opens the switch of control water pipe, core is by water
Inner sleeve is gone out and entered to pressure, and the muddy water into inner sleeve is flowed out through rear baffle central incision；After core is gone out completely, open
Water fender takes core barrel away, opens cutter, so that sliding block is slid into core end along guide rail with a scale, close cutter, tighten
Fastening bolt is eliminated part core epidermis using scoop, exposes fresh face from front to back, convenient for naming and being layered to soil layer, rock
Core and cannot be slided arbitrarily backward due to the blocking of end cutter.Later, fastening bolt is unclamped, sliding block is made to be led along with a scale
Rail slides, and according to the scale on guide rail with a scale, closes cutter, and core is cut to the core of setting length；The rock that will be cut
Core takes out from inner sleeve, is carried in rock core box.
Further, the present invention also provides another well head cores to hold the application method with cutting device, specifically such as
Under：
In use, placing plastic rock core in the inner sleeve in advance holds pipe, core barrel is then proposed into well head, it will
It is placed on outer tube, along outer tube forward slip, is resisted through outer tube and inner sleeve junction, closes water fender；Unload with
The connected drilling rod of core barrel, water pipe is connected with core barrel, opens water pipe control switch, and core is gone out by water pressure into inner sleeve
Pipe, the muddy water into inner sleeve are flowed out through rear baffle central incision；After core is gone out completely, core barrel is taken away, opens cutter,
So that sliding block is slid into core end along guide rail with a scale, close cutter, tighten fastening bolt, is eliminated from front to back using scoop
Part core epidermis, exposes fresh face, and convenient for naming and being layered to soil layer, core, and cannot be to due to the blocking of end cutter
Arbitrarily sliding afterwards.Later, fastening bolt is unclamped, so that sliding block is slided along guide rail with a scale, according to the quarter on guide rail with a scale
Degree, closes cutter, core is cut to the core of 1m long；Pipe and core are held after cutting together with plastic rock core to take out together, on ground
It is put on face neatly, it is labelled, it takes pictures.
Beneficial effects of the present invention are as follows：
One, the configuration of the present invention is simple, it is easy to use, whole device use integral structure, with put with.
Two, the present invention is cheap, convenient for promoting.
Three, The present invention reduces the actions once bent in handling process, reduce labor intensity of operating staff.
Four, it present invention reduces the requirement to levelling of the land degree and place size, avoids before starting operation every time all
It is laid with the work of waterproof cloth or hardwood plate, convenient for quickly carrying out operation.
Five, core layering precision and core quality is greatly improved in the present invention, effectively prevent core bending, distortion, fracture.
Six, the present invention effectively prevent core and mud pollution place, reduces the workload of recovery place original appearance behind whole hole
