    摘要: A gate valve box adaptor structure, the present invention provides a permanent support for the key box bonnet that is unaffected by the surrounding environment. The adaptor is supported on the gate valve to a positive location for the key box bonnet at a level which prevents infiltration of soil and moisture into the bonnet. The adaptor is provided with a resilient gasket of a unique design to provide a cushion and to create a seal for the bonnet on the gate valve. A plurality of liquid infiltration prevention structures for preventing liquid infiltration into manhole assemblies.

    摘要: An improved liquid infiltration adapting structure for preventing liquid infiltration around a gate valve box. The structure has an annular tube structure that is tapered to more easily receive a mating pipe. The tube structure may also comprise at least one bead for further securing the mating pipe. The adapting structure is also improved by providing a stepped inner flange for ease of installing the structure around the gate valve box.
