All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] To ensure that the oblique holes drilled outside the tray, which are not parallel to the anchor cable holes, can connect with the anchor cable holes, an embodiment of this utility model provides a construction device for obliquely connecting anchor cable holes. Referring to Figures 1 and 2, Figure 1 is a schematic diagram of one embodiment of the construction device for obliquely connecting anchor cable holes, and Figure 2 is a schematic diagram of another embodiment. The construction device for obliquely connecting anchor cable holes may include a connecting locator, which may include a tray 1, a hollow clamping device 2, a fixing device 3, and a hollow locator 4; the fixing device 3 is disposed on... The inner side of the tray 1 has a first end and a second end connected to the tray 1 and evenly distributed on both sides of the hollow locator 4, and a third end connected to the side wall of the hollow clamp 2; the hollow clamp 2 is disposed on the inner side of the tray 1, and has openings at both ends; the hollow locator 4 is obliquely disposed on the inner side of the tray 1, with one end connected to the tray 1 and having a first opening leading to the outside of the tray 1, and the other end exposed on the inner side of the tray 1 and having a second opening, and the other end of the hollow locator 4 is in the same plane as the third end of the fixer 3.

[0022] Specifically, the first end of the hollow locator can be tightly attached to the surrounding rock wall on the outside of the tray. The first and second ends of the fixing device are positioned in the middle of the hollow locator. The other end of the hollow locator and the third end of the fixing device are positioned in the same plane. The third end of the fixing device is connected to a hollow clamping device so that the hollow clamping device and the hollow locator are in the same plane, thereby enabling the oblique hole drilled outside the tray that is not parallel to the anchor cable hole to connect with the anchor cable hole.

[0023] The construction device for inclined connecting anchor cable holes provided in this embodiment of the utility model includes a tray, a hollow clamping device, a fixing device, and a hollow positioning device. The fixing device is disposed inside the tray, with its first and second ends connected to the tray and evenly distributed on both sides of the hollow positioning device, and its third end connected to the side wall of the hollow clamping device. The hollow clamping device is disposed inside the tray, with openings at both ends. The hollow positioning device is inclinedly disposed inside the tray, with one end connected to the tray and having a first opening leading to the outside of the tray, and the other end exposed inside the tray and having a second opening. The other end of the hollow positioning device and the third end of the fixing device are in the same plane. This facilitates the connection between the inclined holes drilled outside the tray that are not parallel to the anchor cable holes and the anchor cable holes.

[0024] Referring to Figure 2, which is a schematic diagram of another embodiment of the construction device for inclined connecting anchor cable holes of this utility model, in order to make the hollow clamping device and the hollow positioning device in the same plane, in some embodiments, the fixing device includes a first fixing device 31, a second fixing device 32 and a third fixing device 33; the first fixing device 31 and the second fixing device 32 are disposed on the inner side of the tray, and their first ends are both connected to the tray and evenly distributed on both sides of the hollow positioning device 4, and their second ends are both connected to the first end of the third fixing device; the third fixing device 33 is disposed in the middle of the first fixing device 31 and the second fixing device 32, and its second end is connected to the side wall of the hollow clamping device 2, and the hollow clamping device 2 and the hollow positioning device 4 are in the same plane.

[0025] Specifically, the fixing device can be composed of three fixing devices connected together, including a first fixing device, a second fixing device, and a third fixing device. The first plane containing the first fixing device, the second plane containing the second fixing device, and the third plane containing the tray surround the hollow positioning device. The third fixing device connects the hollow positioning device and the hollow clamping device to the same plane.

[0026] For example, when the hollow locator is an inclined cylindrical structure and the hollow clamping device is a cylindrical structure, the third end of the fixing device, the centerline of the inclined cylinder, and the centerline of the hollow clamping device can all be in the same plane. Therefore, when the drill bit and drill rod are inserted into the hollow locator to construct the inclined hole of a preset length, it helps to ensure that the inclined hole can connect with the anchor cable hole within the designed distance. This allows for sealing and grouting of the anchor cable hole, increasing the length of the anchoring section, improving the strength of the surrounding rock of the anchor cable hole, and enhancing the anchor cable support effect.

[0027] To save on the manufacturing cost of the fastener, in some embodiments, the fastener includes a hollowed-out polygonal plate-shaped fastener.

[0028] Specifically, the fastener can be composed of multiple hollowed-out sheet-like structures, which can be triangular, quadrilateral, pentagonal, or other shapes. The fastener can also be composed of multiple cylinders, and the fastener can be hollowed out, which can save on the manufacturing cost of the fastener while ensuring the fastening effect.

[0029] Referring to Figure 3, which is a schematic diagram of another embodiment of the construction device for inclined connecting anchor cable holes of the present invention, in order to seal and grout anchor cable holes at different heights, in some embodiments, the hollow locator includes at least two inclined circular tubes disposed on the inner side of the tray.

[0030] Specifically, multiple inclined tubes can be set on the tray, and the inclination angle of each inclined tube can be the same or different. The inclination angle can be 30 degrees, 45 degrees, 60 degrees, etc.

[0031] Referring to Figure 3, for example, the area above the tray is surrounding rock, and the area above the anchor cable hole 6 is the anchoring section 61. A first inclined circular tube and a second inclined circular tube with different angles can be set on the tray. The first ends of the first and second inclined circular tubes are both connected to the tray and are close to the surrounding rock wall. The second ends of the first and second inclined circular tubes are both exposed on the inner side of the tray. A drill bit and a drill rod 5 can be inserted into the inclined circular tubes from the second ends of the first and second inclined circular tubes to construct a first inclined hole 41 and a second inclined hole 42 of a preset length on the surrounding rock so that the inclined holes can communicate with the anchor cable hole 6.

[0032] In some embodiments, the hollow clamping device includes a suspended circular tube disposed inside the tray.

[0033] Specifically, the clamping device can be a suspended circular tube.

[0034] In order to fix the position of the hollow clamp and prevent slippage, in some embodiments, the hollow clamp further includes a fastener, which is disposed on the side wall of the hollow clamp and has a length of 10mm to 1000mm.

[0035] Specifically, the fastener can be used to fix the position of the hollow clamp.

[0036] In some embodiments, the fastener includes one of a screw, a wedge, or a clamp.

Referring to Figure 4, the method includes:

[0039] S1: Pass the hollow clamp through the exposed section of the anchor cable and place the hollow locator against the surrounding rock wall on the outside of the tray.

[0040] Specifically, the hollow positioner may include at least two inclined circular tubes disposed on the inner side of the tray, and the inclination angle of each inclined circular tube may be the same or different, and the inclination angle may be 30 degrees, 45 degrees, 60 degrees, etc.

[0041] S2: Determine the angle and position of the tilting hole.

[0042] Specifically, the inclined hole is generally located on the outside of the tray. The angle and position of the inclined hole to be selected can be determined according to the desired sealing and grouting height, thereby enabling the sealing and grouting of anchor cable holes at different heights.

[0043] S3: Insert the drill bit and drill rod into the hollow locator to construct the inclined hole of the preset length so that the inclined hole can be connected with the anchor cable hole.

[0044] Specifically, after determining the angle and position of the inclined hole, the drill bit and drill rod can be inserted into the hollow locator corresponding to the inclined hole for construction, and the inclined hole of a preset length can be constructed to connect the inclined hole and the anchor cable hole.

Then, the angle and position of the inclined hole are determined. Finally, a drill bit and drill rod are inserted into the hollow locator to construct the inclined hole of a preset length, so that the inclined hole can connect with the anchor cable hole. This ensures that the inclined hole drilled outside the tray, which is not parallel to the anchor cable hole, can connect with the anchor cable hole.

[0046] In order to seal and grout anchor holes at different heights, in some embodiments, determining the angle and position of the inclined holes includes: determining the angle and position of at least two of the inclined holes; inserting the drill bit and drill rod into the hollow locator to construct the inclined holes of a preset length includes: inserting the drill bit and drill rod into at least two of the hollow locators to construct at least two inclined holes of a preset length so that the inclined holes can communicate with the anchor holes.
