Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a portable protective device for workers working in a deep foundation pit. Background Art

[0002] For the existing deep foundation pit workers' protective equipment, its types are relatively few, and there is no protective equipment designed for special situations. The existing solutions are common foundation pit protection fences, pile and sheet pile support fences, etc., which can all be used as fences for deep foundation pits. During construction, foundation pit protection fences are generally placed around the foundation pit. They are a common safety facility in construction sites or other deep excavation projects, designed to ensure the safety around the site and prevent people, vehicles or other objects from accidentally falling or entering dangerous areas. They clearly define the area around the site, reduce the chance of accidents, and protect the safety of people and property inside and outside the site. Fences usually use eye-catching colors and signs, have good visibility, and can effectively warn surrounding pedestrians and vehicles to pay attention to dangerous areas. This helps reduce the risk of people mistakenly entering dangerous areas and reminds them to take necessary safety measures. Foundation pit fences can restrict unauthorized personnel or vehicles from entering the construction site and prevent unauthorized personnel from entering dangerous areas, thereby ensuring the safety order and construction progress of the construction site.

[0003] Pile-row and sheet-pile support fences are generally used in deep foundation pits. Pile-row and sheet-pile support fences are two common support structures in deep foundation pit projects. Their main function is to provide support and protection for the boundaries of the foundation pit to prevent accidents such as soil collapse, foundation sliding or pit collapse. To provide stable support, the pile-row support fence constructs the support structure of the foundation pit by driving piles, which can effectively support the surrounding soil and foundation to prevent them from collapsing or sliding. To strengthen the boundaries of the foundation pit, the pile-row support fence arranges the piles along the boundaries of the foundation pit to form a solid support wall, which effectively protects the boundaries of the foundation pit and prevents the soil from tilting inward or collapsing. To prevent water seepage, the pile-row support fence fills waterproof materials between the piles, which can effectively prevent groundwater or rainwater from infiltrating into the foundation pit, keep the foundation pit dry, and facilitate construction work. The role of sheet pile support fence is to provide temporary support. Sheet pile support fence provides temporary support by sinking sheet piles into the ground to prevent soil collapse or sliding around the foundation pit and ensure the safety of the construction site. To limit soil displacement, sheet pile support fence arranges sheet piles around the foundation pit to form a temporary wall, which limits the displacement and deformation of the soil and protects the safety of surrounding buildings and underground facilities. In general, both row pile and sheet pile support fences play an important role in deep foundation pit projects. Their main role is to provide temporary support and protection to ensure the safety and smooth progress of the foundation pit construction process. The specific type of support structure to be selected is usually determined by factors such as the specific requirements of the project, soil conditions, construction environment and economic considerations. These fences are usually made of materials such as metal, are strong and durable, and can effectively withstand external pressure and impact.

[0004] Existing foundation pit protection fences have significant performance, but existing support fences are prone to the following disadvantages: these fences can only be used for protection around the foundation pit, but not inside the foundation pit. They can only be used as basic foundation pit protection fences. Therefore, when working in a deep foundation pit of 4 to 5 meters deep, they cannot play a protective role for personnel. For pile-type and sheet-pile support fences, the construction period is long. The pile-type support fence requires the pile body to be driven first, and then the retaining wall is built. The construction period is relatively long, which may affect the overall project progress; the construction cost is high. The pile-type support fence requires a large number of piles and retaining materials, and the construction cost is high, especially when the soil is hard or deep excavation is required. The cost is higher; it cannot meet the safety protection requirements of the top of the foundation pit, the width cannot be flexibly changed, and it cannot be used for foundation pit protection of different sizes. It cannot meet the flexible construction requirements of various foundation pits, and the scope of use is small. The protection effect in the deep foundation pit will also weaken with the increase of the foundation pit depth, and there are safety hazards. Utility Model Content
