Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to a concrete rectangular trough with safety protection. Background Art

[0002] Concrete rectangular trough is a prefabricated concrete component used in the fields of construction and civil engineering. It is mainly made of a mixture of raw materials such as cement, sand, and stone. It is generally used for drainage, especially in scenes such as roads and farmlands.

[0003] After the concrete rectangular trough is installed in the ditch, multiple concrete slabs are placed on the top of the concrete rectangular trough to effectively isolate external debris, such as garbage, fallen leaves, etc., to prevent them from entering the rectangular trough and causing blockage or affecting its function. At the same time, it can withstand a certain load from vehicles or pedestrians to ensure the normal use of the rectangular trough and the space above it, and prevent people from being hoisted into the concrete rectangular trough. However, most of the existing concrete slabs are placed directly on the top of the concrete rectangular trough. If the concrete slab does not need to be covered under the soil layer in the later stage, it is easy for the concrete slab to be displaced by external force or children's moving, which can easily cause damage to the concrete slab. At the same time, it will also cause the top of the concrete rectangular trough to be exposed, which will pose a safety hazard. Utility Model Content
