Inspection chamber for a pipe structure for drainage or sewerage

Inspection chamber for a pipe structure for drainage or sewerage, the chamber having an inspection entrance at a first side for connecting up with an inspection shaft, the chamber further being provided with a feet-structure at a second side, the first side and the second side being opposite sides of the inspection chamber, the feet-structure comprising at least two feet which are in combination constructed and arranged to:

• stabilize the inspection chamber when positioned on a supporting ground in such a way that the inspection entrance is at an upper position, therewith hindering sideways falling of the inspection chamber;
• and
• maintain a manufactured shape of an inspection entrance of another one of such an inspection chamber when the feet-structure is placed in a mating position with the inspection entrance of that other one of such an inspection chamber;
• and of which each foot itself is constructed and arranged to:
• resist sinking of the inspection chamber into a sandy ground when positioned on such a sandy ground in such a way that the inspection entrance is at an upper position, wherein the inspection entrance for connecting up with an inspection shaft lies in an imaginary plane, and wherein each of the feet comprises a base plate extending in a direction that is parallel to that imaginary plane, and wherein at least one of the base plates extends over an area that corresponds to 5 to 40% of an area defined by the inspection entrance and/or at least one of the base plates has an edge that would cover a part of an inner periphery of the inspection entrance of that other one of such an inspection chamber, when in the mating position.
