Siphon pit Ø1000

The manholes for sanitation of the RASAN brand consist of several elements made of elements made of PE using the rotational moulding technique.

The manholes for sanitation are made of several elements made of PE using the rotational moulding technique.

The The manholes are supplied with the desired height and for this purpose these elements are welded together. welded together; or they are supplied in single pieces to be joined together on site with a are joined together on site by means of a rubber gasket.

In both cases the union is perfect and watertight between the different pieces, which are provided with which are provided with reinforcement ribs, resulting in a highly resistant assembly to the high resistance to earth pressure.

Also Polyethylene is also perfectly resistant to all the components of domestic and industrial waste water and is domestic and industrial wastewater and is resistant to most acids and aggressive sales. acids and aggressive sales.

RASAN RASAN manholes are manufactured in the following diameters:

D800

D1000

D1200

D2000

The wells of D800, D1000 and D1200, are fitted with stainless steel protected with PE and equidistant every 30 cm.

The D2000 manholes are fitted with a fixed aluminium ladder with rungs equidistant every 28 cm. equidistant every 28 cm.

All D2000 manholes are fitted with a fixed aluminium ladder with steps equidistant every 28 cm.

All wells are fitted with an eccentric reduction at the top. eccentric reduction. This reduction is D600 in the D800 and D1000 shafts, D600 or D800 in the D800 and D1000 shafts, and D600 or D800 in the D1000 shafts. D600 or D800 in D1200 wells, and D600, D800, D1000 or D1200 in D2000 wells. D2000 wells.

In the for through wells (D800, D1000 and D1200), the inner bottom of the well has a ribbed is ribbed so that it is easy to channel the water, preventing it from remaining stagnant. water from still remaining stagnant.

The manholes are supplied with the connections prepared according to the needs of the according to the needs of the project or they can be made on site by means of bi-labelled joints. bilabiate joints. In both cases with the possibility of connecting a smooth or corrugated pipe. corrugated pipe.

As a final result we obtain a perfectly watertight polyethylene manhole, which prevents any infiltration of water water infiltration into the ground or vice versa, which makes these wells ideal for ideal for land with phreatic levels and avoids the contamination of aquifers. contamination of aquifers.
