Description

Technical Field

[0001] The utility model relates to the field of safety protection devices, in particular to an adjustable engineering foundation pit safety protection device. Background Art

[0002] The engineering foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane size. Since the foundation pit may exist for a period of time, in order to prevent people from falling into the foundation pit, it is necessary to set a guardrail around the foundation pit to prevent people from entering and improve safety. In the prior art, the Chinese utility model type patent with the public document number: CN214740502U discloses a foundation pit safety protection device for highway engineering. The utility model can not only play a protective effect on the foundation pit, but also bend and adjust according to the shape of the foundation pit, so as to provide more comprehensive safety protection for the foundation pit.

[0003] However, when the shape of the foundation pit is irregular, the length of the side of the foundation pit is also variable. In this utility model, it is not enough to simply allow the two protective plates to be bent to fit the angle of the foundation pit. The length of the guardrail between the columns also needs to be adjusted according to the length of the side of the foundation pit. However, the angle of the foundation pit and the length of the side do not necessarily occur at the same time. In this utility model, after the protective plate is bent, the straight-line distance between the columns will gradually decrease. The two occur at the same time, which is too restrictive and not very practical, and therefore needs to be improved. Utility Model Content
