Description

Technical Field

[0001] This application relates to the field of building construction equipment technology, and in particular to a device for drilling holes in earthen walls during building construction. Background Technology

[0002] Anchor bolt support refers to a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as in underground chamber construction such as tunnels and mining areas.

[0003] In the construction of anchor bolt support on slopes, it is necessary to drill holes in the slope. However, the existing technology directly uses anchor bolt drilling. During this drilling process, soil inside the hole will fall into the drilled hole, resulting in soil debris falling into the hole when the concrete is poured, which reduces the quality of the pouring and requires re-drilling, thus reducing construction efficiency. Utility Model Content

[0007] The bracket is installed on the outside of the wall;

[0008] The sleeve is slidably mounted on the bracket;

[0009] An enlarged head anchor bolt includes a rod body and a head. The rod body is disposed inside the sleeve and extends to the outside of the sleeve at both ends. The head is fixedly connected to the rod body.

[0010] A rotating bearing is provided at the end of the sleeve, and the head is connected to the rotating bearing via a connecting rod. The enlarged head anchor rod and the sleeve can rotate relative to each other.

[0011] Furthermore, the support includes two legs and a crossbeam disposed on the top of the two legs. The top of the crossbeam is provided with a slide rail, a slider is slidably connected to the slide rail, a universal joint is slidably connected to the slider, and a clamp is connected to the other end of the universal joint. The clamp can be connected to the sleeve.

[0012] Furthermore, the bottom of the support leg is provided with a base.

[0013] Furthermore, the outrigger is a retractable outrigger.

[0014] Furthermore, the enlarged head anchor bolt is a hollow anchor bolt.

[0015] Furthermore, the support leg is provided with perforated ear plates on both sides, and the perforated ear plates are provided with limiting pins.

[0016] The above-mentioned at least one technical solution adopted in the embodiments of this application can achieve the following beneficial effects: during the drilling process, after the anchor rod enters the hole, it can drive the casing to enter together. The casing can prevent the soil above the hole wall from falling. After the hole is drilled, the anchor rod is grouted while the anchor rod is being withdrawn, which greatly improves the construction efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] This specification provides an embodiment of a borehole drilling device for earth walls in building construction. Please refer to [link / reference]. Figure 1 As shown, it includes a bracket 1, a sleeve 2, an enlarged head anchor rod, and a rotating bearing 4.

[0023] The support 1 is located on the outside of wall A; the sleeve 2 is slidably mounted on the support 1. In one possible embodiment, the support 1 includes two legs 11 and a crossbeam 12 located at the top of the two legs. The top of the crossbeam 12 has a slide rail 13, on which a slider 14 is slidably connected. A universal joint 15 is slidably connected to the slider 14, and the other end of the universal joint is connected to a clamp 16, which can be connected to the sleeve. A base 17 is located at the bottom of the legs to improve support stability. The end of the universal joint is rotatably connected to the clamp via a pivot, improving the flexibility of directional adjustment.

[0024] The enlarged-head anchor bolt includes a rod body 31 and a head 32. The rod body 31 is disposed inside the sleeve 2 and extends to the outside of the sleeve 2 at both ends. The head 32 is fixedly connected to the rod body 31. A rotating bearing 4 is disposed at the end of the sleeve 2. The head 32 is connected to the rotating bearing 4 through a connecting rod 5, allowing the enlarged-head anchor bolt and the sleeve to rotate relative to each other. The enlarged-head anchor bolt is a hollow anchor bolt.

[0025] When using it, install the bracket on the side of the wall to be drilled, as positioned. Please refer to [link / reference needed]. Figure 2 As shown, after the enlarged head anchor is installed inside the casing, the casing is installed in the clamp and supported by a bracket. The tilt angle can be adjusted via a universal joint, reducing the labor required for manual operation and adapting to different angles, thus improving flexibility during use. During drilling, the anchor enters the hole, pulling the casing along with it. The casing prevents soil from falling off the hole wall. After drilling, grouting is performed through the anchor, and the anchor is withdrawn while grouting, greatly improving construction efficiency.

[0026] Further optimized, the outriggers are retractable, adaptable to different working conditions.

[0027] In a further preferred embodiment, the outriggers are each provided with perforated lugs 6, and each perforated lug is provided with a limiting pin 7. During use, the outriggers are connected to the earthen slope via the limiting pins, improving stability.
