Alhamdulillah.... Akhirnya kerja DN siap juga setelah bertungkus-lumus selama beberapa hari. Esok tinggal nak print dan susun untuk dijadikan dokumen tender. Lepas DN dah siapkan BQ (Bill of Quantity), tetiba DN rasa nak share sesuatu dengan kalian. Mana tahu berguna kan... Apa salahnya berkongsi. Betul tak...
Kali ini DN nak berkongsi tentang saiz telephone manhole. Kalian mesti tahu talian telefon yang masuk ke rumah kalian akan melalui pole (tiang) tapi tiang telefon ini kalian akan dapati bukan berada sepanjang-panjang jalan. Jalan utama nak masuk ke rumah kalian kebiasaannya akan ada telephone manhole ini.
Jika kawasan rumah kalian tiada tiang telefon, bermakna kesemuanya adalah underground dan kalian boleh nampak telephone manhole sepanjang jalan. Untuk bangunan-bangunan selain dari rumah kebanyakannya menggunakan telephone manhole ini.
Sebenarnya kalian takkan nampak sebijik2 manhole ini sebabnya ia sudah dikambus dalam tanah. Yang akan kalian nampak cuma cast iron cover yang terletak di atas pre-cast concrete top slab. Begini lah rupa telephone manhole tersebut...
Ini adalah contoh JC9 manhole. Manhole ini berbeza dari segi saiz dan bilangan duct way. Jom DN berkongsi dengan kalian jenis-jenis manhole tersebut.

- weight = 12.5 ton
2. R1B

6. JB30

ReplyDeleteThis brings us to proper fittings to be used in backyard drainage systems. The more fittings used in a drainage system or as many know as French drains (which we will discuss in this article and more in-depth in a future article soon to follow) will slow down the water so an ideal system is using the least amount of fittings as possible.
