- Corrugated polyethylene manholes 𝐂𝐨𝐫𝐫𝐮𝐠𝐚𝐭𝐞𝐝 𝐏𝐄 𝐌𝐚𝐧𝐡𝐨𝐥𝐞𝐬
➖➖➖➖➖➖➖➖➖➖
Corrugated polyethylene manholes 𝐂𝐨𝐫𝐫𝐮𝐠𝐚𝐭𝐞𝐝 𝐏𝐄 𝐌𝐚𝐧𝐡𝐨𝐥𝐞𝐬 / 𝐃𝐨𝐮𝐛𝐥𝐞 𝐖𝐚𝐥𝐥 𝐏𝐄 are now widely used in main lines of sewage transport by slope
💮 The manholes are characterized by their superior resistance to acids and gases produced from wastewater, so they do not need any internal protection, as well as resistance from outside to highly aggressive soils that do not need external protection.

♦ Condition of winding polyethylene pipes 𝔻.𝕎 ℙ𝔼
---------------------------------------
☀️ The connection of the polyethylene manholes with the polyethylene pipes by welding with a short connection of polyethylene head / tail 𝑆𝑜𝑐𝑘𝑒𝑡 /, then the connection of the pipes from the inlet and outlet, and the fixed connection in the manhole can also be connected with the corrugated polyethylene pipes by means of a (copling) polyethylene bushing Meander 𝐂. 𝐏𝐄 which acts as a flexible connection
♦ ️ Condition of plastic pipes𝕌𝕡𝕧𝕔
--------------------------
☀️ The connection of the polyethylene manholes with the plastic pipes by welding the وصلة / tail / polyethylene short joint, then the connection of the joint with the plastic pipes by means of a plastic bushing as a flexible connection
The condition of the fiberglass pipes
----------------------------
☀️ The connection of the polyethylene manholes with the fiberglass pipes by welding a short connection of polyethylene tail / /, then welding a short connection of fiberglass with the polyethylene connection with the resin, then the connection of the fiberglass connection with the fiberglass pipes through a fiberglass bushing 𝐺𝑅𝑃 𝐺𝑅𝑃. That works as a flexible link
Types of corrugated polyethylene manholes
➖➖➖➖➖➖➖➖➖➖
Polyethylene manholes differ according to the diameter of the pipes 𝐃𝐍
1️⃣- Central manhole ℂ𝕖𝕟𝕥𝕣𝕒𝕝 / 𝕊𝕥𝕒𝕟𝕕𝕒𝕣𝕕
-------------------------------
Central manholes are fountains on the same axis as the piping axis
Central manholes are used if the diameter of the pipes is less or equal to the diameter of the manhole
🔹 Central manholes are manufactured in diameters 𝔻ℕ / 𝕀𝔻 {𝟠𝟘𝟘 ~ 𝟙𝟘𝟘𝟘 𝕞𝕞}
2️⃣- Manhole Tangential 𝕋𝕒𝕟𝕘𝕖𝕟𝕥𝕚𝕒𝕝
-------------------------
Tangential manholes are manholes touching the body of the pipes, meaning that the manhole is not on the axis of the pipes
Tangential manholes are used in the event that the diameter of the pipes is greater than the diameter of the standard manhole
3️⃣- Special manhole 𝕊𝕡𝕖𝕔𝕚𝕒𝕝
--------------------
🔹 Concrete manholes equipped with 𝑃𝐸 inlets and outlets, suitable for connection with polyethylene pipes.
♦ The connection of the fixed urinary joints with the concrete manholes shall be sealed against leakage either by using a sealant gasket 𝑅𝑢𝑏𝑏𝑒𝑟, or by using joints with a non-shrinking material 𝑁𝑜𝑛- 𝑆ℎ𝑟𝑖𝑛𝑘
