Description

Technical Field

[0001] This utility model relates to the field of prefabricated inspection well technology, specifically a prefabricated inspection well mold. Background Technology

[0002] Precast manholes are industrially produced municipal infrastructure components. They are made by prefabricating concrete components in a factory and then rapidly assembling them on the construction site. They are mainly used for the inspection, maintenance, and connection of urban underground pipe networks (such as drainage, power, and communication systems). Precast manhole molds are steel molds used for the mass production of concrete manholes, characterized by their sturdiness, durability, and ability to be repeatedly demolded. A precast manhole mold consists of an inner mold cylinder and an outer mold cylinder, forming a casting cavity between them.

[0003] Currently, when using precast manhole molds, the outer mold cylinder is assembled on the inner mold cylinder with bolts, which makes it inconvenient to disassemble and assemble the outer mold cylinder. The casting surfaces of the inner and outer mold cylinders are prone to sticking, causing problems such as difficulty in demolding the precast manholes and even damage during demolding. In addition, the casting cavity between the inner and outer mold cylinders is narrow, which makes it difficult to clean the forming surface inside the casting cavity. Utility Model Content
