Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit protection, and specifically relates to a foundation pit Internet of Things fence. Background Art

[0002] The foundation pit is a pit dug at the design location of the foundation according to the base elevation and the plane size of the foundation. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the slope can be used to stabilize the slope, and the slope size is determined according to relevant construction regulations. For deep excavations and nearby buildings, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing; if there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation; in cold areas, natural cold air freezing method can be used for excavation, etc.

[0003] After the foundation pit is dug, a fence is needed to prevent accidental falling. Although the existing fence is equipped with Internet of Things cameras with the advancement of technology, it is not convenient to perform adaptive assembly when assembling the fence during actual use. That is to say, it is not convenient to adjust and lock the angle of stable connection according to the shape of the foundation pit, and the overall height of the fence is not convenient to be adaptively adjusted. At the same time, there is no effective early warning and protection mechanism when the fence accidentally topples or is accidentally knocked over. Utility Model Content

[0004] The purpose of the utility model is to provide an Internet of Things fence for a foundation pit to solve the problem that although the existing fences mentioned in the above background technology are equipped with Internet of Things cameras as technology advances, it is not convenient to perform adaptive assembly when assembling the fence during actual use, that is, it is not convenient to adjust and lock the angle of stable connection according to the shape of the foundation pit, and the overall height of the fence is not convenient to perform adaptive adjustment. At the same time, there is no effective early warning and protection mechanism when the fence accidentally topples over or is accidentally knocked over.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foundation pit Internet of Things fence, including a fence frame, the fence frame including a lower guardrail, a plurality of mounting plates are fixedly installed on the side of the lower guardrail, the mounting plates are provided with mounting holes, a plurality of fixed columns and two connecting columns are fixedly installed on the upper surface of the lower guardrail, the two connecting columns are located at the two end positions of the lower guardrail, the top ends of the plurality of fixed columns and the top ends of the two connecting columns are fixedly installed with the same upper guardrail, two rotating sleeves are rotatably installed on the outer surface of one of the connecting columns, and two fixed sleeves are fixedly installed on the outer surface of the other connecting column, and the outer surfaces of the two rotating sleeves and the two The outer surface of the fixed sleeve is fixedly installed with assembly blocks, and the two assembly blocks at the same horizontal height are staggered one above and one below.
