摘要 |
<p>The invention relates to an inspection chamber part (3, 4, 5) comprising a spigot- socket structure (10). This spigot- socket structure comprises a spigot shaped first section (11) and a socket shaped second section (12). The sections are integrally connected to each other, at least initially and at least one of the sections is integrally connected to the inspection chamber part. The first and second section have a compatible shape, such that if the integral connection between the first and second section were to be severed, the first section could closely fit into the second section so as to establish a spigot- socket connection. The inspection chamber part may be integral part of a monolithic inspection chamber or be a separate part, such as a base, a shaft or a cone from which a modular inspection chamber can be assembled. The invention furthermore relates to a method for preparing such an inspection chamber part for installation.</p> |
