ZEKAN cable manholes are used in the construction of cable ducts as access points for the installation of elements, crossing, branching and cable inspection. Other utility elements can also be installed in them. Compared to concrete or masonry manholes, they are considerably lighter, the parts are made of HDPE. They can be installed quickly and easily and, due to the modular system, they allow the actual change of the manhole size according to the project or construction requirements. Their mechanical load capacity is high, corresponding to the parameters of the ČSN EN 124 standard.
The preformed holes for the protectors in the cable manholes are at the same spacing as the protectors in the spacers. The holes for the protector outlet from the manhole are easily made with a grubbing drill for the required protector diameter.
The manholes are supplied with covers with load class B 125 and D 400. The lids of the covers are made of cast iron and are housed in steel frames. The covers in class B 125 are installed directly on the manhole body. According to the installation instructions, the D 400 class covers have to be under-concreted to form a concrete lifting tower to ensure the required mechanical strength. The covers are designed for load class D 400 in a travelling surface environment, they are not intended for heavy traffic in exposed locations. If covers for paving are required, they can be supplied – the lids and the perimeter of the manhole are fitted with stainless steel frames at the required height (according to the paving used). If covers for paving are required, these can be supplied – the lids and the perimeter of the manhole are fitted with stainless steel frames at the required height (according to the paving used).
