Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to an auxiliary device for positioning anchor bolts in tunnel construction. Background Technology

[0002] Tunnel engineering is a crucial component of highway engineering structures. In the initial support construction of tunnels, anchor bolt support is a key process for ensuring the stability of the surrounding rock, and its construction quality directly affects the overall safety and long-term stability of the tunnel. Currently, the installation and positioning of anchor bolts within tunnels typically relies on traditional methods employed by construction workers, using simple tools such as tape measures and calipers combined with visual inspection, or directly determining the drilling positions of the anchor bolts based on experience. However, the complex working environment within tunnels, limited lighting conditions, and often uneven rock wall surfaces all contribute to significant difficulties and errors in manual positioning, leading to inaccurate positioning, low efficiency, and potentially increased construction costs due to rework.

[0020] According to one aspect of this application, embodiments of this application provide an auxiliary device for anchor bolt positioning in tunnel construction, which can be found in conjunction with the following description. Figure 1 and Figure 2 The auxiliary device for anchor bolt positioning in tunnel construction includes an arc-shaped fixed rod 1, a first telescopic component 2, a positioning rod 4, and a second telescopic component 5. The first telescopic component 2 is located at the end of the arc-shaped fixed rod 1 and has a fixing hole 3 for fixing it to the tunnel steel mesh device. The positioning rod 4 is arranged perpendicular to the arc-shaped fixed rod 1 and one end of the positioning rod 4 is fixedly connected to the arc-shaped fixed rod 1. The second telescopic component 5 is located at the other end and has an anchor bolt positioning hole 6 for positioning the anchor bolt drilling position.

[0021] In this embodiment, the auxiliary device for anchor bolt positioning in tunnel construction includes an arc-shaped fixed rod 1, a first telescopic component 2, a positioning rod 4, and a second telescopic component 5. The arc-shaped fixed rod can change its length through the first telescopic component 2, and the positioning rod 4 can change its length through the second telescopic component 5, allowing the auxiliary device to be flexibly adjusted to adapt to different tunnel cross-sectional dimensions and anchor bolt spacing parameters of different designs, thus exhibiting good versatility. The auxiliary device is connected to the tunnel steel reinforcement mesh through the device fixing hole 3 located on the first telescopic component 2, ensuring the stability of the auxiliary device during construction. The anchor bolt positioning hole 6 on the second telescopic component 5 provides a precise guiding reference for drilling anchor bolt holes, effectively avoiding errors from manual visual inspection and significantly improving the installation accuracy of the anchor bolts.

[0022] In one embodiment, see Figure 1 and Figure 2 The arc-shaped fixing rod 1 is an arched structure adapted to the contour of the tunnel's initial support surface, with the first telescopic component 2 at each end. The end of the first telescopic component 2 has a device fixing hole 3 for fixing the device to the tunnel's reinforcing mesh using connectors such as wires, cable ties, or bolts.

[0023] In one embodiment, see Figure 2 The positioning rod 4 is vertically connected to the top of the arc of the arc-shaped fixing rod 1. This design ensures that the positioning rod 4 is located on the center line or key position of the tunnel cross section, so that the positioning of the anchor rod has better symmetry and reference on the tunnel outline.

[0024] In one embodiment, see Figure 1 and Figure 2 The arc-shaped fixing rod 1 has at least two adjustable length specifications through the first telescopic component 2. The first telescopic component 2 adopts a sleeve-type telescopic structure, that is, steel pipes of different diameters are connected to each other and locked by a pin or a set bolt as a locking mechanism. It is inserted into a series of equally spaced locking holes in the arc-shaped fixing rod 1 to achieve multi-level adjustment of length. The adjustable length specifications of the arc-shaped fixing rod include 1.6 meters and 2.0 meters, and can also be set to other commonly used length specifications.

[0025] In one embodiment, see Figure 1 and Figure 2 The positioning rod 4 has at least three adjustable length specifications via the second telescopic assembly 5. The second telescopic assembly 5 also employs a sleeve-type telescopic structure, consisting of steel pipes of different diameters interlocked and locked using pins or set bolts. These are inserted into a series of pre-set, equally spaced locking holes on the positioning rod 4 to achieve multi-level length adjustment. The adjustable length specifications of the positioning rod 4 include 0.8 meters, 1.0 meters, and 1.2 meters, and can also be set to other commonly used length specifications. An anchor positioning hole 6 is provided at the end of the second telescopic assembly 5 to provide precise guidance for the drill bit.

[0026] In one embodiment, see Figure 1 The device fixing hole 3 is used to fix the device to the steel mesh in the tunnel through the connector. The device fixing hole 3 is a through hole for wire, cable tie or bolt to pass through in order to fix the device to the steel mesh in the tunnel.

[0027] Before the tunnel anchor bolt support construction, the arc-shaped fixing rod 1 and the positioning rod 4 are adjusted to the required lengths using the first telescopic component 2 and the second telescopic component 5, according to the circumferential spacing and radial angle of the anchor bolts determined in the design drawings. They are then securely tied to the steel mesh at the tunnel working face through the device fixing holes 3. Subsequently, the drill bit is aligned with the anchor bolt positioning hole 6 for drilling. After completing the work at this position, the connecting parts are loosened, the device is moved to the next position and re-fixed, allowing for rapid and precise positioning of subsequent anchor bolts.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
