发明名称 Method and apparatus employing modular engageable components for formation of maintenance hole platforms
摘要 A method for forming a maintenance hole base for the bottom surface of a maintenance shaft using a configurable modular mold and thermoforming or rotational molding. The modular mold is formed of individual members of groups of central core components engageable to surrounding periphery components to yield a mold which will form the appropriate engagement and communication pathways for the base when installed. Polymeric material is employed with the mold to yield a finished component configured for use in the base of the maintenance shaft.

主权项 1. A method for forming a maintenance hole base, the method comprising: providing a first component having a top surface comprising at least one recess; providing a plurality of second components, the second components being configured to engage with the first component and thereby form a mold, wherein at least one of the second components has a top surface comprising at least one recess configured to align with the at least one recess of the first component so as to at least partially define at least one channel in the mold; and providing a polymeric material configured to be molded against the mold.
