Description

Technical Field

[0001] The utility model relates to the technical field of underground continuous walls, in particular to an underground continuous wall groove wall reinforcement structure. Background Art

[0002] Underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to build a unit trench section. If the trench wall collapses after the trench is formed, it will make it impossible to continue construction, greatly affecting the construction progress. Therefore, the trench wall needs to be reinforced after the trench is formed;

[0003] For this purpose, the China Patent Network has published an underground continuous wall groove wall reinforcement device, with the publication number CN215165483U, which includes multiple side panels, multiple flange panels, multiple web panels, multiple flange panel and side panel plug-in mechanisms, and multiple side panel and web panel plug-in mechanisms. The bottom of the side panel is serrated, and the two ends of the side panel and one end of the adjacent flange panel are respectively connected in sequence through the flange panel and side panel plug-in mechanisms to form a groove wall side panel assembly whose length matches the length of the underground continuous wall groove wall; the two ends of the web panel and the corresponding middle of the flange panel are respectively vertically connected through the side panel and web panel plug-in mechanisms, thereby connecting two parallel groove wall side panel assemblies and multiple web panels vertically spaced between the two groove wall side panel assemblies into multiple grids of groove wall supports connected in a straight line. The utility model has a simple structure and is easy to construct, and can be modularly manufactured in the factory. The construction site occupies a small area, the construction period is short, and the construction safety risk is low, which can largely ensure the stability of the underground continuous wall groove;

[0004] However, there are still the following disadvantages: although the existing device can reinforce the trench wall, the size of the trench wall itself needs to be measured and laid out during the reinforcement process. After reinforcement, the device cannot adapt to underground continuous wall trench walls of other specifications. Therefore, an underground continuous wall trench wall reinforcement structure is proposed. Utility Model Content

[0039] In this embodiment, a buffer mechanism 3 is provided to buffer the device above the base plate 1 when it moves, thereby preventing parts from being damaged due to excessive vibration during movement. After the base plate 1 moves to a specified position, the height of the two buffer plates 301 can be adjusted according to the road conditions, so that the base plate 1 can be in a relatively horizontal state.

[0040] When in use, the base plate 1 can be moved to the underground continuous wall groove wall that needs to be reinforced through the self-locking wheel 4.

When the moving plate 210 moves, the two reinforcement plates 225 can be opened to both sides through the two control rods 211 and the two connecting blocks 212. When the two reinforcement plates 225 are opened to both sides, the underground continuous wall groove wall can be reinforced. When the two reinforcement plates 225 are opened to both sides, the lifting block 217 can be moved upward. When the lifting block 217 moves upward, the telescopic block 224 and the extrusion block 218 can be driven to move synchronously. When the extrusion block 218 moves upward, the elastic member 222 can make the extrusion block 218 move to the right side. After the adjustment of the two reinforcement plates 225 is completed, when the extrusion block 218 moves to the right side, the tooth plate 216 can support the space between the two reinforcement plates 225.
