Description

Technical Field

[0001] The utility model relates to an anchor rod, in particular to a microbial pipe seam anchor rod. Background Art

[0002] The pipe seam anchor is a commonly used anchor form in the engineering industry. It is a new type of anchor that is full-length anchored and actively reinforces the surrounding rock. Its three-dimensional part is a high-strength steel pipe with a longitudinal slit. First, a hole is drilled in the rock mass, and then the steel pipe with a slit is driven into the hole. When the pipe seam anchor is installed in a hole slightly smaller than the pipe diameter, radial pressure and friction to prevent the surrounding rock from sliding can be immediately applied to the hole wall over the entire length. In addition, the supporting force of the anchor tray plate puts the surrounding rock in a three-dimensional stress state, and the rock formation is stabilized, making the construction simple and quick. Because some rock masses contain a certain amount of moisture, or the rock mass itself is relatively soft, this will reduce the friction between the hole wall and the pipe seam anchor, reduce the bonding performance between the steel pipe and the rock mass, and it is difficult to meet higher anchor fixing requirements. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a microbial pipe seam anchor rod which can improve the bonding performance between a steel pipe and a rock mass.

[0004] The technical solution adopted by the utility model is: the utility model comprises an anchor rod tube body, a tube slit parallel to the center of the anchor rod tube body is provided on the tube wall of the anchor rod tube body, a plurality of wall holes are also provided on the tube wall of the anchor rod tube body, the internal space of the anchor rod tube body is connected with the external space of the anchor rod tube body through the tube slit and the wall holes, and a microbial filler is provided in the anchor rod tube body.

[0005] Furthermore, the anchor rod tube body is a steel tube.

[0006] Furthermore, sealing rubber plugs are provided at both ends of the anchor rod tube body, and sealing rubber strips are provided on the tube seam.

[0007] Furthermore, baffles or nets are provided at both ends of the anchor rod tube body and on the tube seam to prevent the microbial filler from overflowing. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] like Figures 1 to 3 As shown, in this embodiment, the utility model includes an anchor rod tube body 1, and in this embodiment, the anchor rod tube body 1 is a steel tube. A pipe seam 2 parallel to the center of the anchor rod tube body 1 is provided on the tube wall of the anchor rod tube body 1, and a plurality of wall holes 3 are also provided on the tube wall of the anchor rod tube body 1. The internal space of the anchor rod tube body 1 is connected to the external space of the anchor rod tube body 1 through the pipe seam 2 and the wall holes 3, and a microbial filler 4 is provided in the anchor rod tube body 1.

[0013] In this embodiment, the microbial filler 4 includes Bacillus pasteurianus, which is a bacillus widely present in soil, water and air. Bacillus pasteurianus is well known for its spores formed under adverse conditions. These spores have extremely strong tolerance, can survive in extreme environments, and germinate again under suitable conditions. Bacillus pasteurianus has excellent metabolic adaptability and can utilize a variety of carbon sources and nitrogen sources, so that it can survive and reproduce in different ecological environments, and can absorb carbon dioxide in the air and produce crystalline calcium carbonate.

[0014] In this embodiment, the microbial filler 4 includes quartz sand, which is a hard, wear-resistant, and chemically stable silicate mineral. Filling the anchor rod tube body 1 with quartz sand can not only support the inner wall of the steel pipe, but also accelerate the reproduction of Bacillus pasteurianus due to its good permeability.

[0015] In this embodiment, sealing plugs or baffles or screens are provided at both ends of the anchor rod tube 1, and sealing strips or baffles or screens are provided on the pipe seam 2. The design of the blocking structure can effectively prevent quartz sand mixed with Bacillus pasteurianus from scattering from the anchor rod tube 1.

[0016] like Figure 4 As shown, in order to further improve the bonding performance between the steel pipe and the rock mass, Bacillus pasteurianus and quartz sand are loaded into the steel pipe. When the microbial pipe seam anchor of the utility model is installed in place, there is a gap between the pipe wall of the steel pipe and the hole wall of the rock mass 6. Bacillus pasteurianus will gradually absorb carbon dioxide in the air to produce a crystalline calcium carbonate layer 7, which gradually fills the gap, thereby improving the bonding performance between the pipe seam anchor and the rock mass.

[0017] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
