Description

Technical Field

[0001] This utility model belongs to the field of hydraulic tunnel construction technology, and in particular relates to a device for positioning the angle of consolidation grouting holes. Background Technology

[0002] Hydraulic tunnels are an important component of water conservancy projects. They include arc-shaped tunnel linings, and the tunnel linings generally require vertically penetrating consolidation grouting holes extending outwards.

[0003] During the construction of consolidation grouting holes, the location of the consolidation grouting holes is often determined by measurement and layout. However, it is not possible to accurately determine the verticality of the consolidation grouting holes relative to the tunnel lining based on the cross-section of the arc-shaped tunnel lining. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a consolidation grouting hole angle positioning device, which can accurately position the verticality of the construction consolidation grouting hole relative to the tunnel lining.

[0005] The objective of this utility model is achieved through the following technical solution: A consolidation grouting hole angle positioning device, comprising: The tunnel single-arm drilling rig head includes a drill rod support and a drill rod for drilling consolidation grouting holes, with the axis of the drill rod coinciding with the axis of the drill rod support. An arc-shaped positioning plate is fixedly connected to the outer end of the drill rod support. The axis of the drill rod support is perpendicular to the arc-shaped positioning plate. The arc-shaped positioning plate is provided with a through hole for the drill rod to pass through. The outer surface radius of the arc-shaped positioning plate matches the inner surface radius of the tunnel lining.

[0006] The beneficial effects of adopting the above technical solution are as follows: When constructing the consolidation grouting hole, by adjusting the angle of the tunnel single-arm drilling rig head, the outer surface of the arc-shaped positioning plate can be completely fitted with the inner surface of the tunnel lining, so that the drill rod support and the drill rod on it are perpendicular to the tunnel lining, thereby making the consolidation grouting hole vertically opened on the tunnel lining, and thus accurately positioning the verticality of the construction consolidation grouting hole relative to the tunnel lining.

[0007] Furthermore, the arc-shaped positioning plate includes a first arc-shaped surface located on the outer side and used to conform to the inner surface of the tunnel lining.

[0008] The beneficial effects of adopting the above technical solution are: the arc-shaped positioning plate uses the first arc-shaped surface to fit the inner surface of the tunnel lining.

[0009] Furthermore, the arc-shaped positioning plate includes a second arc-shaped surface located on the inner side, the axis of the second arc-shaped surface coinciding with the axis of the first arc-shaped surface.

[0010] Furthermore, the second arc-shaped surface is welded to the outer end of the drill pipe support, and the axis of the drill pipe support is perpendicular to the second arc-shaped surface.

[0011] The beneficial effect of adopting the above technical solution is that the drill rod support is fixedly connected to the arc-shaped positioning plate by welding with the second arc-shaped surface.

[0012] Furthermore, the outer end of the drill pipe support is provided with an end face for welding the second arc-shaped surface.

[0013] The beneficial effects of adopting the above technical solution are as follows: the drill rod support uses the end face of the outer end to weld with the second arc-shaped surface, thereby realizing a fixed connection with the arc-shaped positioning plate.

[0014] Furthermore, the end face is arc-shaped and fits the second arc-shaped surface.

[0015] The beneficial effects of adopting the above technical solution are as follows: this setting makes the contact area between the drill pipe support and the arc-shaped positioning plate larger, thereby making the connection between the drill pipe support and the arc-shaped positioning plate more stable.

[0016] Furthermore, the middle part of the arc-shaped positioning plate is fixedly connected to the outer end of the drill pipe bracket.

[0017] The beneficial effects of adopting the above technical solution are as follows: This setting avoids the arc-shaped positioning plate being subjected to force on one side, thereby facilitating the outer surface of the arc-shaped positioning plate to fit the inner surface of the tunnel lining.

[0018] Furthermore, a through hole is provided in the middle of the arc-shaped positioning plate.

[0019] Furthermore, the axis of the through hole coincides with the axis of the drill pipe support.

[0020] The beneficial effect of adopting the above technical solution is that this setting facilitates the passage of the drill pipe.

[0021] Furthermore, the diameter of the through hole matches the outer diameter of the drill bit on the drill rod.

[0022] The intended effect of adopting the above technical solution is that this setting allows for the use of through holes to assist in the positioning and installation of the drill rod.

[0023] The beneficial effects of this utility model are as follows: During the construction of consolidation grouting holes, by adjusting the angle of the tunnel single-arm drilling rig head, the outer surface of the arc-shaped positioning plate can be completely fitted with the inner surface of the tunnel lining, so that the drill rod support and the drill rod on it are perpendicular to the tunnel lining. This allows the consolidation grouting holes to be opened vertically on the tunnel lining, thereby accurately positioning the verticality of the construction consolidation grouting holes relative to the tunnel lining.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] This utility model provides a device for positioning the angle of a consolidation grouting hole, such as... Figure 1-4 As shown, it includes: The tunnel single-arm drilling rig head includes a drill rod support 2 and a drill rod 4 for drilling consolidation grouting holes 11. The axis of the drill rod 4 coincides with the axis of the drill rod support 2. Arc-shaped positioning plate 3 is fixedly connected to the outer end of drill rod support 2. The axis of drill rod support 2 is perpendicular to arc-shaped positioning plate 3. Arc-shaped positioning plate 3 is provided with through hole 33 for drill rod 4 to pass through. The outer surface radius of arc-shaped positioning plate 3 matches the inner surface radius of tunnel lining 1. Among them, the inner surface of the tunnel lining 1 is the first lining surface 12, and the arc-shaped positioning plate 3 can be a steel plate.

[0028] Understandably, during the construction of the consolidation grouting hole 11, by adjusting the angle of the tunnel single-arm drilling rig head, the outer surface of the arc-shaped positioning plate 3 can be made to completely fit with the inner surface of the tunnel lining 1, so that the drill rod support 2 and the drill rod 4 on it are perpendicular to the tunnel lining 1, thereby making the consolidation grouting hole 11 vertically opened on the tunnel lining 1, and thus accurately positioning the verticality of the construction consolidation grouting hole 11 relative to the tunnel lining 1 to meet the construction requirements.

[0029] It should be noted that both the tunnel lining 1 and the arc-shaped positioning plate 3 have the side closer to the axis as the inner surface and the side farther from the axis as the outer surface.

[0030] In one embodiment, the arc-shaped positioning plate 3 includes a first arc-shaped surface 31 located on the outside and used to fit the first lining surface 12. The arc-shaped positioning plate 3 uses the first arc-shaped surface 31 to fit the inner surface of the tunnel lining 1.

[0031] In one embodiment, the arc-shaped positioning plate 3 includes a second arc-shaped surface 32 located on the inner side, the axis of the second arc-shaped surface 32 coincides with the axis of the first arc-shaped surface 31; the second arc-shaped surface 32 is welded to the outer end of the drill rod bracket 2, and the axis of the drill rod bracket 2 is perpendicular to the second arc-shaped surface 32.

[0032] Understandably, the drill pipe support 2 is fixedly connected to the arc-shaped positioning plate 3 by welding to the second arc-shaped surface 32.

[0033] It should be noted that the second arc-shaped surface 32 can also be connected to the outer end of the drill rod support 2 by means of detachable connection such as bolt connection. This is beneficial to replace the arc-shaped positioning plate 3 with different outer surface radii according to the inner surface radius of the actual tunnel lining 1, thereby improving the applicability of the consolidation grouting hole angle positioning device.

[0034] In one embodiment, the outer end of the drill pipe support 2 is provided with an end face 21 for welding the second arc-shaped surface 32.

[0035] It is understandable that the drill rod bracket 2 uses the end face 21 of its outer end to weld to the second arc-shaped surface 32, thereby achieving a fixed connection with the arc-shaped positioning plate 3.

[0036] In one embodiment, the end face 21 is arc-shaped and fits the second arc-shaped surface 32, and a hole for the drill rod 4 to pass through is correspondingly provided on the end face 21.

[0037] Understandably, this arrangement is intended to increase the contact area between the drill pipe support 2 and the arc-shaped positioning plate 3, thereby making the connection between the drill pipe support 2 and the arc-shaped positioning plate 3 more stable.

[0038] In one embodiment, the middle part of the arc-shaped positioning plate 3 is fixedly connected to the outer end of the drill rod bracket 2.

[0039] Understandably, this design is intended to prevent the arc-shaped positioning plate 3 from being subjected to force on one side, thereby facilitating the outer surface of the arc-shaped positioning plate 3 to adhere to the first lining surface 12.

[0040] In one embodiment, a through hole 33 is provided in the middle of the arc-shaped positioning plate 3, and the axis of the through hole 33 coincides with the axis of the drill rod bracket 2 to facilitate the passage of the drill rod 4.

[0041] In one embodiment, the diameter of the through hole 33 matches the outer diameter of the drill bit of the drill rod 4, so as to use the through hole 33 to assist in positioning and installing the drill rod 4.
