[0002] Excavation face refers to a working surface excavated on the surface or underground in earthwork for underground construction or excavation of underground resources. The excavation face can be horizontal, inclined or vertical, depending on the purpose of excavation and engineering requirements. Support structures are usually required around the excavation face to prevent soil collapse or sliding. Support structures can be steel supports, concrete walls, soil nail walls, anchor supports, etc. The specific choice depends on factors such as the depth of the excavation face, soil properties and surrounding environment.

[0003] When the existing support structure for preventing the excavation surface from being deformed is used, it is generally supported and prevented by the cooperation of the support plate and the diagonal brace rod. However, since the support structure is only supported and fixed to the bottom end of the excavation surface by the diagonal brace rod, and there is no firm positioning structure, the stability of the support is not high and the support may become loose. For this reason, we propose a support structure for preventing the excavation surface from being deformed. Utility Model Content
