In order to solve the technical problem, the utility model is realized by the following scheme: the utility model relates to a supporting structure applied to a weathered rock roadway of a coal mine inclined shaft, wherein a plurality of steel rope anchor rods are anchored along the left side, the right side and the arc top of an arched wall body of the weathered rock roadway, an arched structural body with a channel formed by splicing a plurality of corrugated plates is installed by taking the visible end parts of the steel rope anchor rods as installation points, the lower end of the arched structural body and the ground of the weathered rock roadway are fixed through pre-anchors, and plain concrete is poured between the arched structural body and the wall body of the weathered rock roadway and is cured.
Further, the strength of the plain concrete reaches C20 concrete.
Furthermore, the corrugated plate is a steel corrugated plate.
Further, the corrugated plate has a corrugation direction perpendicular to the channel.
Compared with the prior art, the utility model has the beneficial effects that: the support structure applied to the weathered rock roadway of the inclined shaft of the coal mine forms an arch-shaped structural channel by using the steel corrugated plate and concrete, and the steel rope anchor rod is pre-anchored before the steel corrugated plate is installed and concrete is poured. The support structure has high safety performance and is beneficial to the rapid tunneling of the inclined shaft of the coal mine.

FIG. 1 is a schematic view of a supporting structure of a weathered rock roadway of a coal mine inclined shaft.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and thus the protection scope of the present invention is more clearly and clearly defined. It should be apparent that the described embodiments of the present invention are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or may be communicated with each other inside the two elements, or may be wirelessly connected or wired connected. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1: the concrete structure of the utility model is as follows:
referring to the attached drawing 1, the supporting structure applied to the weathered rock roadway of the inclined shaft of the coal mine is characterized in that a plurality of steel rope anchor rods 2 are anchored along the left side, the right side and the arc top of an arched wall body of the weathered rock roadway, an arched structural body with a channel formed by splicing a plurality of corrugated plates 4 is installed by taking the visible end parts of the steel rope anchor rods 2 as installation points, the lower end of the arched structural body and the ground of the weathered rock roadway are fixed through a pre-anchor 3, and plain concrete 1 is poured between the arched structural body and the wall body of the weathered rock roadway and is cured.
According to a preferable technical scheme of the embodiment, the strength of the plain concrete 1 reaches C20 concrete. The C20 concrete means the concrete with the strength grade of C20, and the concrete with the strength grade of C20 means that: represents the compressive strength of a standard cube of 20MPa, namely 15MPa < fcu<25 MPa. And the concrete strength grade is divided according to the standard value of the cubic compressive strength. The standard value of cubic compressive strength refers to a value in the overall distribution of compressive strength measured by a standard test method in 28-day age of a cubic standard test piece with the side length of 150mm manufactured and maintained by a standard method, and the percentage of the strength lower than the value is not more than 5%. The concrete strength grade adopts a symbol C and a cube compression strength standard value (in N/mm)2Meter) is shown.
According to a preferred technical scheme of the embodiment, the corrugated plate 4 is a steel corrugated plate.
In a preferred embodiment of the present invention, the corrugated plate 4 has a corrugation direction perpendicular to the channels.
In conclusion, the supporting structure applied to the weathered rock roadway of the inclined shaft of the coal mine forms an arch-shaped structural channel by using the steel corrugated plate and concrete, and the steel rope anchor rod is pre-anchored before the steel corrugated plate is installed and the concrete is poured. The support structure has high safety performance and is beneficial to the rapid tunneling of the inclined shaft of the coal mine.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
