Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a roadway support base and a roadway support device. Background Technology

[0002] Tunnel support is a crucial component in mining, tunnel construction, and other engineering projects, directly impacting construction safety and project progress. Traditional tunnel support bases often employ fixed structures, which are ill-suited for complex and variable geological environments.

[0003] In practical engineering, the surrounding rock conditions vary greatly in different areas of the tunnel. Fixed-spacing and fixed-shape bottom beam assemblies cannot be adjusted according to site conditions, leading to uneven distribution of support force and stress concentration in some areas, posing safety hazards. Furthermore, fixed-connection bases cannot flexibly adapt to spatial changes during tunnel excavation, and cannot dynamically adjust their position according to actual needs, affecting the stability and reliability of the support system. In addition, traditional bases lack effective adjustment mechanisms; when tunnel deformation occurs, they cannot be adjusted in a timely manner to maintain the support effect, increasing maintenance costs and potentially delaying project progress.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0051] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0052] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0053] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.
