Abstract
The invention relates to a novel inner-cooling soft rock core drill. The novel inner-cooling soft rock core drill is characterized by comprising a drill provided with cooling water circulation channels in the interior, a water-blocking soft plug and heat-conduction copper rings and realizing drill cooling by internal cooling water circulation and the heat-conduction copper rings. The novel inner-cooling soft rock core drill can be used in the existing vertical core-drilling machine, has a simple structure, is convenient for production and popularization, and has wide application prospects.
Description
Technical field
The invention belongs to soil test test specimen manufacture field, particularly a kind of novel inner-cooled soft rock coring bit is applicable to the core work of soft rock sample.
Technical background
Soft rock refers to that intensity is low, factor of porosity big, degree of consolidation is poor, influenced significantly by structural surface cutting and weathering or contain the pine of a large amount of swelling clay mineral, diffusing, soft, incompetent beds; Mostly this rocks is mud stone, shale, siltstone and shale ore deposit rock, is the geologic medium of the complicacy of natural formation.
Soft rock is distributed widely in earth surface, and only mud stone and shale just take up an area of about 50% of all rocks of table.In China; Area, the northwestward, the Yunnan-Guizhou Plateau, the clear low river basin in Hunan, the Sichuan Basin, northeast, Gansu and southeastern coast and the Northeast all have soft rock to distribute in flakes or sporadicly; Fast development along with the great infrastructure construction of China; The normal soft rock strata that meets with in the engineering construction in fields such as traffic engineering, hydroelectric project and municipal works; Because characteristics such as soft rock has that intensity is low, factor of porosity is big, degree of consolidation is poor, swelling clay mineral content height, thus soft rock to meet water after-tack disintegration effect obvious, brought a large amount of engineering problems and caused the generation of a series of disaster accidents.
Therefore, carry out that soft rock is softening, disintegration properties and mechanical property research becomes one of the hot issue in Geotechnical Engineering field, shop experiment is a kind of important research means.In the research of soft rock shop experiment; The normal sample preparation difficult problem that meets with: because soft rock has the characteristics that are prone to softening disintegration behind the water of meeting; Under the immersion of sample preparation instrument chilled water with the mechanical disturbance of sample preparation instrument under soft rock very easily destroy; Cause the sample preparation failure,, invented a kind of novel inner-cooled soft rock coring bit to this problem.
Summary of the invention
The objective of the invention is; Need drench during to the vertical corning machine processing of existing rock soft rock sample and water a large amount of chilled waters; The problem that causes the soft rock disintegration to destroy; Developed a kind of novel inner-cooled soft rock coring bit, provide a kind of and can be applied to existing vertical corning machine, and the soft rock that chilled water need not directly to contact with the soft rock sample has been got the core mode.
A kind of novel inner-cooled rock coring bit that the present invention relates to; It is characterized in that containing the drill bit of chilled water circulation passage by inside; Sealing cork and heat conduction copper ring are formed; Utilize inner chilled water circulation and the acting in conjunction of heat conduction copper ring, the soft rock that the realization chilled water need not directly to contact with the soft rock sample is got the core mode.
1) sealing cork
Sealing cork plug is in the drill bit internal upper end, and inner chilled water circulation passage water inlet is exposed in the cork top, and the cork bottom is the space that holds core, and cork makes chilled water to pass through in chilled water two spaces that are not connected up and down that are separated in core.Chilled water circulation passage water inlet is discharged from the cork upper end.
2) heat conduction copper ring
Heat conduction copper ring hoop is in bit exterior, with the temperature conduction of the drill body part of no-cooling-water passage to the drill body part that contains cooling-water duct.
3) high-strength alloy steel bit
The drill bit internal upper end contains screw thread; Identical with the used drill bit screw thread of common vertical corning machine, can be installed on the common vertical corning machine, this moment, sealing cork top formed confined space; After getting into, the chilled water of vertical corning machine can only get into circulation passage from the water inlet of drill bit internal chilled water circulation passage; After in circulation passage, flowing, finally the freeing port through the chilled water circulation passage flows out, because there is pressure in the chilled water that inserts; Therefore chilled water is ejection from the form of freeing port discharge, can not fall on the rock sample of below.
The present invention has the following advantages:
1, can be installed on the existing vertical corning machine of rock, need not existing vertical corning machine is reequiped, have a extensive future.
2, structure is simple relatively, realizes easily, is easy to commercial running and produces.

Embodiment
Specify use-pattern of the present invention below in conjunction with accompanying drawing 1,2.
(1) heat conduction copper hoop is installed in the drill bit outside.
(2) the sealing cork is filled in from drill bit below, sealing cork upper end plug stops to fill in action during to chilled water circulation passage water inlet.
(3) drill bit is installed on the vertical corning machine, opens cooling water switch, whether inspection sealing cork leaks.
(4) the soft rock sample is installed, is got core in a conventional manner.
Claims (1)
1. novel inner-cooled soft rock coring bit; It is characterized in that containing the drill bit of chilled water circulation passage by inside; Sealing cork and heat conduction copper ring are formed; Wherein sealing cork plug is in the drill bit internal upper end, and inner chilled water circulation passage water inlet is exposed in the cork top, and the cork bottom is the space that holds core; Heat conduction copper ring hoop is in bit exterior, with the temperature conduction of the drill body part of no-cooling-water passage to the drill body part that contains cooling-water duct; The drill bit internal upper end contains screw thread; Identical with the screw thread of the used drill bit of common vertical corning machine, can be installed on the common vertical corning machine, this moment, sealing cork top formed confined space; The chilled water of vertical corning machine gets into the water inlet entering circulation passage of back from drill bit internal chilled water circulation passage; After in circulation passage, flowing, finally the freeing port through the chilled water circulation passage flows out, because there is pressure in the chilled water that inserts; Therefore chilled water is ejection from the form of freeing port discharge, can not fall on the rock sample of below.
