Inspection chamber

Telescopic 400/315 manhole for inspection and maintenance of drainage systems. Can also be used as a stormwater grate manhole (in this case, the customer service representative should be informed that you wish a grate cover, instead of a full cover).

The manhole is made of smooth-walled polyethylene pipe with ring stiffness SN2 kN/m². Load capacity of the cast iron cover 40T.

It is a modular manhole, which means that the customer will assemble the manhole components directly on site (the working depth of the well can be adjusted between 1.3-1.8 m.) The manhole consists of a plastic base cover (not welded to the pipe), a De400 riser pipe, a 400/315 telescopic ring, a De315 telescope pipe and a cast iron cover. You can choose between full or grate cast iron cover. In addition, the price includes two rubber in-situ gaskets for the De110 pipe connection.

Manhole components will be delivered as separate parts.

If the customer needs a manhole deeper than 1.8m or with a larger diameter (e.g. 560/500), please contact our customer service directly and we will provide you with a quotation.
