Description

Technical Field

[0001] This utility model belongs to the field of road construction technology in Yecheng City, and more specifically, it relates to an adaptive stabilization device for road foundation pits. Background Technology

[0002] In urban road construction, foundation pit excavation is an essential step. Traditional foundation pit support methods, such as reinforced concrete supports, can effectively provide structural support, but they are complex to construct, time-consuming, and not easily recyclable, generating a large amount of construction waste and adversely affecting the environment. Furthermore, due to variations in geological conditions, deformation is inevitable during foundation pit excavation, and traditional support methods often struggle to effectively adapt to this deformation, potentially leading to foundation pit instability.

[0003] Self-stabilizing foundation pit support technology uses steel components instead of traditional reinforced concrete supports, enabling vertical excavation and the recycling and reuse of steel components, resulting in significant economic and environmental benefits. However, the existing technology still needs further improvement, particularly in enhancing the adaptability and stability of the support device. Utility Model Content

A plug rod 201 is fixedly welded to the outer end face of the fixing block 22, and the adjustment rod 21 is connected to the inside of the fixing block 22 through thread engagement. After the plug rod 201 at the end of the fixing block 22 is fixedly embedded, the adjustment rod 21 is rotated by rotating the pull rod, so that the stop block 2101 at the end of the adjustment rod 21 fits against the main plate 11 or the side plate 12. At the same time, the plug rod 201 at the end of the stop block 2101 is fixedly inserted into the foundation pit.
