Abstract
The utility model provides a drilling rod fixer is executed in tunnel construction, including a location section of thick bamboo, the internal diameter more than or equal to drilling rod external diameter of a location section of thick bamboo, the outer wall of a location section of thick bamboo is fixed with at least three connector link along circumference distribution, and the outside of every connector link all corresponds and is provided with pre-buried horizontal pole, through turn-buckle fixed connection between connector link and the pre-buried horizontal pole that corresponds, the coupling hook at turn-buckle both ends hooks respectively and locates on connector link and the pre-buried horizontal pole. The method solves the problem that the existing construction method is difficult to ensure the positioning precision of the drilling. Belongs to the field of tunnel construction.
Description
Technical Field
The utility model relates to a tunnel construction is executed and is bored drilling rod fixer belongs to the tunnel construction field.
Background
At present, drill rod positioning in tunnel construction is a big difficulty, and the drill rod positioning can only be guaranteed by means of stable drilling of an operator to control the drill rod in the existing method, but the mode is extremely unstable, the problems of drilling deviation and the like can often occur, and the drilling precision cannot be guaranteed.
Disclosure of Invention
The utility model provides a drilling rod fixer is bored in tunnel construction to it is difficult to guarantee the problem of drilling positioning accuracy to solve current construction method.
For realizing above-mentioned purpose, plan to adopt such a tunnel construction to execute and bore drilling rod fixer, including a location section of thick bamboo, the internal diameter more than or equal to drilling rod external diameter of a location section of thick bamboo, the outer wall of a location section of thick bamboo is fixed with at least three connector link along circumference distribution, and the outside of every connector link all corresponds and is provided with pre-buried horizontal pole, through turn-buckle fixed connection between connector link and the pre-buried horizontal pole that corresponds, the coupling hook at turn-buckle both ends hooks respectively on locating connector link and pre-buried horizontal pole.
In the drill rod fixer, the inner diameter of the positioning cylinder is 5-30mm larger than the outer diameter of the drill rod;
in the drill rod fixer, the embedded cross rods are embedded in the tunnel face;
in the drill rod fixer, a steel plate is welded and fixed on the outer wall of the positioning cylinder, and the connecting fastener is a connecting hole formed in the steel plate or a steel fastener welded and fixed on the steel plate;
in the drill rod fixer, the connecting buckles are all arranged on the same cross section of the positioning cylinder;
among the aforementioned drilling rod fixer, the outer wall of a location section of thick bamboo is provided with three connector link along circumference equidistant distribution, and three pre-buried horizontal pole one-to-one sets up in the outside of three connector link.
Compared with the prior art, the utility model discloses in tunnel construction, confirm the drilling position of drilling rod earlier, use drilling as the center again, select three position along circumference distribution ground, it is pre-buried to pre-buried horizontal pole on the face, aim at the location of drilling with a location section of thick bamboo again, the connector link in the location section of thick bamboo outside is respectively through the turn-buckle connection pre-buried horizontal pole, tighten up the turn-buckle, keep a location section of thick bamboo aim at drilling and with drilling coaxial can, it can to pass the location section of thick bamboo with the drilling rod again and carry out the drilling operation, can guarantee the precision of drilling position well, and can also effectively avoid the drilling rod to beat partially under the condition that a location section of thick bamboo has certain length, suitable popularization and application.

fig. 2 is a bottom view of fig. 1.
Detailed Description
To further clarify the objects, technical solutions and advantages of the present invention, a more particular description of the invention will be rendered by reference to the appended drawings, which are illustrated in the appended drawings.
Examples
Referring to fig. 1 and 2, this embodiment provides a drilling rod fixer is executed in tunnel construction, including a location section of thick bamboo 1, the internal diameter of a location section of thick bamboo 1 is 20mm bigger than the drilling rod external diameter, and the outer wall of a location section of thick bamboo 1 is fixed with three connector link 2 along circumference equidistant distribution, and the outer wall welded fastening of a location section of thick bamboo 1 has steel sheet 5, connector link 2 is for offering connecting hole or the steel knot of welded fastening on the steel sheet 5, and connector link 2 all sets up in the same cross section department of a location section of thick bamboo 1 to guarantee location section of thick bamboo 1 axial stability, the outside of every connector link 2 all corresponds and is provided with pre-buried horizontal pole 3, and the one end of pre-buried horizontal pole 3 is all pre-buried on the face, through 4 fixed connection of turn-buckle between connector 2 and the pre-buried horizontal pole 3 that corresponds, and the hook respectively on connector link 2 and pre-buried horizontal pole 3.
During the use, confirm the drilling position of drilling rod earlier, use drilling as the center again, select three position along circumference distribution ground, it is pre-buried to pre-buried horizontal pole on the face, aim at the location section of thick bamboo drilling location again, the connector link in the location section of thick bamboo outside connects pre-buried horizontal pole through the turn-buckle respectively, tighten up the turn-buckle, keep the location section of thick bamboo aim at drilling and with the drilling coaxial can, pass the drilling rod again the location section of thick bamboo carry out the drilling operation can, can guarantee the precision of drilling position well, and then guarantee construction precision and accuracy.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
