Abstract
The invention discloses a processing technique of irregular rock during indoor drilling coring, and relates to a rock processing technique in drilling a cylinder test sample from irregular rock blocks in a laboratory, which is advantageous for fixation processing of a coring machine during rock core drilling in the irregular rock. The processing technique is characterized in that four wood templates (2) form a rectangular frame and the rectangular frame is placed on a base plate (5) to form a pouring mold, next, a rock block (3) is put in the mold and finally, the premixed cement mortar mix is poured into the gap (1) between the rock block and the mold; and besides, cement mortar mix (4) with thickness of 2-3cm is pre-paved in the mold before the rock block is placed so that a drill bit protective layer is formed. The processing technique has the following major advantages that the mold can be reused, the material adopted is easily available and the operation of the processing technique is simple and convenient.
Description
Technical field
The present invention relates to a kind of sillar processing treatment technology when drilling through cylindrical sample in irregular block rock.
Background technology
When carrying out ROCK MECHANICS RESEARCH, the standard cylindrical test specimen is to obtain the experimental subjects that the effective physical and mechanical parameter of rock generally needs.Generally, can be by means of the coring of prospecting by boring time institute, through to its cutting, polish and be used for test job after processing, but long or do not keep properly due to drilling core open-assembly time, can not satisfy the demand of shop experiment test job, often carry out boring and coring indoor to the sillar of fetching from engineering site by means of the rock corning machine this moment, to obtain required standard cylindrical test specimen.But because the rock sample of fetching from engineering site is often also irregular, is not easy to directly be placed on and carries out the boring and coring operation on indoor rock corning machine chassis; Larger acting force between larger vibrations, drill bit end and surface of contact of corning machine when work has in addition increased the fixedly difficulty of irregular rock; Simultaneously, because the corning machine chassis is hardware, when being bored into the sample bottom, if misoperation is easy to damage drill bit because of drill bit contact corning machine chassis.Therefore, insecure if rock is fixed in getting the core process, will cause unnecessary unexpected injury to experimenter and corning machine, also can affect the quality of core-drilling simultaneously.
Summary of the invention
The deficiency that is difficult to fix when the indoor boring and coring for solving irregular rock sample, to be that design is a kind of guaranteeing to need not cutting, destroying under the rock sample prerequisite the technical problem to be solved in the present invention, can effectively irregular rock be fixed on the corning machine chassis, and guarantee corning machine and experimenter's safety in the boring and coring operating process.
In order to solve the problems of the technologies described above; the present invention is based on the clamping plate fixed environment on corning machine chassis; design a kind of mould technology of building of irregular rock; build up the block structure with regular profile indoor irregular rock sample is watered; in the middle of being positioned over clamping plate on the corning machine chassis, it is fixed; successfully solve the fixation problem of irregular block sillar, and by building the special processing technology in mold process, effectively protected corning machine drill bit and experimenter's safety.
Technical solution of the present invention is: select plank sheathing to be assembled into rectangular mould according to the irregular rock profile, and overlay 2 ~ 3cm solid cement mortar mix in mould, in the mould of then irregular rock being packed into after-pouring become that the bottom surface is smooth, the four sides uprightly and the regular block structure that is parallel to each other in twos; Overlay the sand-cement slurry mix as the drill bit protective seam, prevent that drill bit from directly touching the corning machine metal chassis after rock and damage because penetrating; Four regular planars for clamping plate fixedly rock compression face is provided.
The present invention has the beneficial effect of following aspect: 1, moulding is convenient to dismounting with plank sheathing, and is reusable; 2, cement and sandstone are all easily to obtain and cheap building materials; 3, the requirement of strength to the sand-cement slurry mix is not high; 4, be convenient to the fixing of rock; 5, can effectively protect the safety of drill bit.
Description of drawings
Accompanying drawing 1 is the vertical view of rule treatments sillar model
Accompanying drawing 2 is the A-A sectional view of Fig. 1
In figure 1: joints cement mortar block; 2: plank sheathing; 3: irregular rock; 4: overlay 2cm solid cement mortar material; 5: backing plate;
Embodiment
1, make mould: according to getting the rock sample profile from engineering site, make four slightly bigger rectangle plank sheathings (2), and with nail, it is combined into a rectangle wooden frame, then be positioned on the movable pad (5) of surfacing.
2, overlay drill bit protection bed course: the sand-cement slurry mix that will the mix in advance 2 ~ 3cm that packs in mould on backing plate is thick, forms drill bit protective seam (4).
3, place sillar: according to testing requirements boring and coring direction, irregular rock (3) is put into mould, and keeps between sillar and plank sheathing inwall, certain gap being arranged, gap length so that the sand-cement slurry mix that vibrates be advisable.
4, joints cement mortar mix moulding: then with in the sand-cement slurry mix injection sillar that mixes and plank sheathing gap (1), vibrate, floating surface, the amount of injection mix is so that identification rock boundary contour is advisable.
5, maintenance: maintenance 1-2 time-of-week under room temperature environment at last, the sand-cement slurry block can remove plank sheathing after having some strength.
At this moment; after building the mould processing through concrete, irregular block rock has had regular profile, and the sillar steady job when getting core for rock-boring is provided convenience; simultaneously have the thick concrete cushion of 2 ~ 3cm in regular block structure bottom, can effectively protect drill bit to get safety in the core process.
Claims (4)
1. the processing treatment technology of an irregular rock when being used for indoor boring and coring; It is characterized in that: adopt concrete to build the mould technology and irregular rock is wrapped in the sand-cement slurry block with regular shape, rely on fixedly cement bonded sand lumps of corning machine fixture, reach the purpose of fastening irregular rock.
2. the cement bonded sand lumps with regular shape according to claim 1 is characterized in that: the sand-cement slurry block is that bottom surface is smooth, four sidewalls are upright and regular block parallel to each other in twos.
3. according to claim 1 have four sidewalls regular block parallel to each other in twos, and it is characterized in that: the sidewall that is parallel to each other in twos consists of the plane of constraint that fixture stablize imposed load, with better fixedly sand-cement slurry block.
4. concrete block according to claim 1 is built the mould technology, it is characterized in that: during joints cement mortar block, put into irregular rock after wooden model bottom overlays 2 ~ 3cm solid cement mortar mix, pre-matting layer consists of the drill bit protective seam again.
