Abstract
The utility model discloses a kind of core orientation coring fixators, including whole steelframe (1), rock core slot (2), boring positioning plate (3) and rock core fixed plate (4)；Whole steelframe (1) is fixedly connected with rock core slot, makes rock core slot and ground in 45 degree of angles or parallel to the ground；Long cores A is packed into rock core slot；Rock core fixed plate (4) is arranged in long cores side, is fixedly connected with rock core slot (2), radially limits to long cores；Boring positioning plate (3) is fixed on the upper surface of whole steelframe (1), which is provided with circular open.45 degree of angles and orthogonal positioning when the utility model can be realized core hole sampling do not need to carry out complicated calculating and preparation, and easy to operate, sampling is more convenient, and the used time shortens 50%, greatly improves working efficiency.
Description
Technical field
The utility model belongs to engineering geology field, and in particular to a kind of core orientation coring fixator.
Background technique
According to the requirement of sound emission geostress survey, when drilling through oriented core sample, need in diameter > 50mm long cores
6 directions (as shown in following table) take out diameterLength is greater than the short rock core of 40mm, and each direction needs 5
Short rock core more than root.
| Sample azimuth/inclination angle |
| 000°/90° |
| 180°/00° |
| 090°/00° |
| 135°/00° |
| 180°/45° |
| 270°/45° |
At the scene of sampling, the direction of rock core is drawn on the label bus of rock core with marking pen, is directed toward bottom hole from aperture,
And the depth of sampling need to be indicated, oriented core sample is then drilled through according to label directly on rock core with drilling machine.Due to long cores
This does not use the tool of some fixed rock cores such as cylinder, and it is non-directly to drill through the short rock core of orientation on long cores with drilling machine
Often difficult, especially 45 ° of directions drill through short rock core and are difficult to complete.
Utility model content
The purpose of the utility model is to provide a kind of core orientation coring fixators, are in when solving core hole sampling
Horizontal and 45 degree of inclination angles are not easy the problem of positioning.
A kind of the technical solution of the utility model are as follows: core orientation coring fixator, it is characterised in that: including whole steelframe
1, rock core slot 2, boring positioning plate 3 and rock core fixed plate 4；Whole steelframe 1 is fixedly connected with rock core slot, makes the rock core slot be in ground
45 degree of angles or parallel to the ground；Long cores A is packed into rock core slot；Rock core fixed plate 4 is arranged in long cores side, with rock core slot
2 are fixedly connected, and radially limit to long cores；Boring positioning plate 3 is fixed on the upper surface of whole steelframe 1, which is provided with circle and opens
Mouthful.
The utility model has the advantages that 45 degree of angles and orthogonal positioning when the utility model can be realized core hole sampling, do not need
Complicated calculating and preparation are carried out, easy to operate, sampling is more convenient, and the used time shortens 50%, greatly improves
Working efficiency.

Specific embodiment
To keep the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
It is described in further detail.
The utility model provides a kind of core orientation coring fixator, including whole steelframe 1, rock core slot 2, boring positioning plate
3 and rock core fixed plate 4；Each component is welded by channel steel and square steel.
Whole steelframe 1 is fixedly connected with rock core slot, makes rock core slot and ground in 45 degree of angles or parallel to the ground；Long cores
A is packed into rock core slot；The bolt hole C that rock core fixed plate 4 is arranged on long cores side, with rock core slot 2 is bolted, and is made
Rock core fixed plate 4 is tightly sticked together with long cores, thus long cores are radially fixed, prevent long cores from moving in drilling operation
It is dynamic, cause rock core to drill through failure；Boring positioning plate 3 is fixed in the bolt hole B of the upper surface of whole steelframe 1, which is provided with circle
Shape opening starts drilling machine, can drill through the short rock core sample of positioning for being put into drill bit vertically.The position of the circular open with
Need the position of drill hole sampling corresponding.
Rock core slot and ground are illustrated in figure 2 in the structural schematic diagram of entirety steelframe 1 when 45 degree of angles, is used to fix rock
The inclined-plane of heart slot is horizontal by 45 degree of angles；
When rock core slot and ground level, the face that whole steelframe 1 is used to fix rock core slot is horizontal plane.
Each part dimension is as shown in attached drawing 2~5, unit mm.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
