Description

Technical Field

[0001] The utility model relates to the technical field of protection for operations in low spaces, in particular to an upper protection device for operations in low spaces. Background Art

[0002] A foundation pit is a temporary pit excavated for the foundation of a building. The foundation pit is a temporary project and its function is to provide a space so that the foundation masonry work can be carried out in the position specified by the design. The foundation pit excavation volume is calculated according to the volume of the foundation pit. After the excavation is completed, the foundation pit needs to be protected by protective devices to prevent pedestrians from falling into the foundation pit and getting into danger.

[0003] Existing protective devices generally use support rods for protection. The support rods have a relatively simple structure when in use. The construction foundation pit is used for a long time. Due to the influence of weather environment, water will accumulate inside the well-drilled foundation pit. If it is not discharged in time, the accumulated water inside the foundation pit will affect the subsequent construction work. At the same time, due to the influence of rain and snow weather, the soil on the top and both sides of the foundation pit is prone to collapse, which causes a certain degree of damage to the foundation pit, resulting in unnecessary casualties and poor protection performance.

[0004] Therefore, those skilled in the art provide an overhead protection device for working in a low space to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a protective device above working in a low space is proposed. A plurality of fixed bottom plates, baffles and limit plates are connected by mortise and tenon joints. The number and size of the fixed bottom plates, baffles and limit plates can be adjusted according to the size of the foundation pit. At the same time, the mortise and tenon joints can quickly connect and disassemble the protective device, which effectively improves the use efficiency of the protective device. The limit plates can facilitate workers to work near the foundation pit, and the water pump inside the protection box can be used to pump out the accumulated water inside the foundation pit, so that the foundation pit can be prevented from being affected by the accumulated water, resulting in the inability to carry out the foundation pit work, and the accumulation of water inside the foundation pit can also be avoided. Mixing with mud and sand to reduce the mud content causes the strength of the foundation pit to be reduced and cannot be used. Multiple connecting rods can be used to fix multiple baffles and also support the multiple baffles. By fixing the bottom plate, baffles and limit plates, the soil around the foundation pit can be fixed and supported, which can prevent the foundation pit from collapsing due to rain and snow and causing casualties. The limit plates can limit and fix the soil around the foundation pit, which can prevent workers from walking near the foundation pit and falling into the foundation pit due to loose soil around the foundation pit, causing injuries to the workers. At the same time, the limit plates can facilitate workers to work near the foundation pit.
