Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a supporting pile foundation pit supporting device. Background Art

[0002] Pile-anchor support means that when a building's foundation pit is under construction, if the foundation needs to be excavated very deep, the soil around the foundation pit is prone to collapse. In order to ensure the stability of the foundation pit, the foundation pit must be supported;

[0003] For example, a utility model patent with Chinese patent publication number CN214245745U discloses a foundation pit pile anchor support device, including a baffle and a ground. A fixing nail is welded and fixed on one side of the baffle. The baffle is perpendicular to the ground. A slide groove is provided inside the baffle. A limiting tooth is arranged inside the slide groove. A slider is slidably connected inside the slide groove. A reset spring is welded and fixed inside the slider. A fixing tooth is welded and fixed on the other end of the reset spring. The fixing tooth and the limiting tooth are meshed with each other. Blocks are symmetrically welded and fixed on both sides of the slider. A movable seat is welded and fixed on the outer side of the slider. The movable seat is rotatably connected to a support rod through a pin shaft. The other end of the support rod is connected to a connecting seat through a pin shaft. A fixing block is fixed to the connecting seat. The fixing nail and the baffle are connected to a fixing device together;

[0004] It was found during use of the above-mentioned prior art that the device supports the baffle plate by sliding the slider to engage the fixed teeth with the limit teeth, thereby preventing the support rod from slipping and improving the stability of the device. However, the height of the baffle plate of the device is fixed, which is not easy to adapt to foundation pits of different depths. It has certain limitations in use, reduces work efficiency, and thus leads to poor practicality. Utility Model Content
