Abstract
The invention relates to a method for constructing a flow plastic interlayer by adjusting a hole drill. A section of flow plastic interlayer is sandwiched between upper and lower sections of normal strata; and after a drilling machine drills through the flow plastic interlayer, a construction method can be adopted to prevent hole collapse of the flow plastic interlayer and comprises the following steps of: 1, taking the drilling machine out; 2, wrapping a hole protection pipe by using a layer of inverse filtering net, and putting into the flow plastic interlayer section; 3, retracting tool arms of the drilling machine by using hydraulic oil cylinders, putting a drill bit into the hole protection pipe again to make the tool arms stretch out, stretching the hole protection pipe along positive teeth and reverse teeth, namely increasing the diameter of the hole protection pipe, and extruding slot walls; and 4, ensuring that the drilling machine crosses the hole protection pipe by stretching the tool arms, and continuously drilling. By the method, the hole collapse of the flow plastic interlayer can be prevented during drilling or hole cleaning.
Description
One, technical field
The present invention relates to a kind of construction method, particularly a kind of method of adjusting hole drill construction stream to mould interlayer.
Two, background technology:
At present, for existing stream to mould the geology of interlayer, during boring, just strengthen the proportion of mud and denseness and reduce the probability of collapse hole, but, before concrete perfusion, need change slurry to hole body and reduce proportion and the denseness of mud, now may cause again that hole body stream moulds the collapse hole of interlayer.
Three, summary of the invention:
The present invention has overcome above shortcoming, and a kind of method of adjusting hole drill construction stream to mould interlayer is provided.
The present invention is achieved through the following technical solutions:
Between the normal stratum of two sections, accompany one section of stream and mould interlayer, at rig, bore overcurrent and mould after interlayer, for interlayer collapse hole is moulded in anti-fluid stopping, available following construction method:
The first, rig is proposed; The second, guard aperture pipe is wrapped up in to one deck anti-filter net outward, be placed in stream and mould sandwich segment, guard aperture pipe is the cylinder that Elastic Steel is manufactured, comprise second guard aperture pipe and first guard aperture pipe, the two ends of second guard aperture pipe are respectively equipped with several pawls, the two ends of first guard aperture pipe are also respectively equipped with several commutating tooths, the mutual interlock of commutating tooth and pawl; Three, by hydraulic jack, the tool arm of rig is bounced back, again drill bit is placed in guard aperture pipe, tool arm is stretched out, guard aperture pipe is stretched along the place of commutating tooth and pawl, be about to the enlarged-diameter of guard aperture pipe, push cell wall; Four, rig continues boring by the flexible guard aperture pipe of crossing of tool arm.
The present invention has following feature:
When the present invention can prevent from holing again or clear Kong Shiliu mould interlayer collapse hole again.
Four, accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A view.
In figure: 1, normal stratum, 2, stream moulds interlayer, 3, hole wall, 4, second guard aperture pipe, 5, drilling rod, 6, hydraulic jack, 7, tool arm, 8, first guard aperture pipe, 9, commutating tooth, 10, pawl.
Five, the specific embodiment:
Accompanying drawing is a kind of specific embodiment of the present invention, accompanies one section of stream and mould interlayer 2 between the normal stratum 1 of these embodiment two sections, at rig, bore overcurrent and mould after interlayer, and for interlayer collapse hole is moulded in anti-fluid stopping, available following construction method:
(1) rig is proposed;
(2) guard aperture pipe is wrapped up in to one deck anti-filter net outward, be placed in stream and mould sandwich segment, guard aperture pipe is the cylinder that Elastic Steel is manufactured, comprise second guard aperture pipe 4 and first guard aperture pipe 8, the two ends of second guard aperture pipe are respectively equipped with several pawls 10, the two ends of first guard aperture pipe are also respectively equipped with several commutating tooths 9, the mutual interlock of commutating tooth and pawl;
(3) by hydraulic jack 6, the tool arm of rig 7 is bounced back, again drill bit is placed in guard aperture pipe, tool arm 7 is stretched out, guard aperture pipe is stretched along the place of commutating tooth and pawl, be about to the enlarged-diameter of guard aperture pipe, push cell wall;
(4) rig continues boring by the flexible guard aperture pipe of crossing of tool arm.
Claims (1)
1. a method of adjusting hole drill construction stream to mould interlayer, between the normal stratum of two sections (1), accompany one section of stream and mould interlayer (2), at rig, bore overcurrent and mould after interlayer, for anti-fluid stopping, mould interlayer collapse hole, it is characterized in that: available following construction method: the first, propose rig; The second, guard aperture pipe is wrapped up in to one deck anti-filter net outward, be placed in stream and mould sandwich segment, guard aperture pipe is the cylinder that Elastic Steel is manufactured, comprise second guard aperture pipe (4) and first guard aperture pipe (8), the two ends of second guard aperture pipe are respectively equipped with several pawls (10), the two ends of first guard aperture pipe are respectively equipped with several commutating tooths (9), the mutual interlock of commutating tooth and pawl; Three, by hydraulic jack (6), the tool arm of rig (7) is bounced back, again drill bit is placed in guard aperture pipe, tool arm (7) is stretched out, guard aperture pipe is stretched along the place of commutating tooth and pawl, be about to the enlarged-diameter of guard aperture pipe, push cell wall; Four, rig continues boring by the flexible guard aperture pipe of crossing of tool arm.
