Invert Level (IL)
Contoh gambarajah
Camne kita nak tahu berapa invert level (IL) untuk setiap manhole (MH) yang kita sediakan dalam pelan. Sebelum tu, kena ingat... setiap orang mungkin berbeza...
Jom kita tengok contoh pengiraan di bawah... ---->>
Jom kita tengok contoh pengiraan di bawah... ---->>
Gradian Penggalian 1:200
Diberi :
Aras Tanah / Ground
Level = A m
Kedalaman / Depth MH1 = B mm
Jarak / Distance MH1 ke MH2 = C mm
Jarak / Distance MH2 ke MH3 = D mm
Kedalaman MH 1 = B mm
IL MH1 = Aras Tanah –
Kedalaman MH1
= A – B
= E
Beza kedalaman MH 1 & MH 2
= Jarak
MH1 & MH 2
200 ( Gradian Penggalian)
= C
200
= F mm
Kedalaman MH2
= kedalaman MH 1 + beza kedalaman MH1 dan MH2
= B + F
= G mm
IL MH 2 = Aras tanah – Kedalaman MH2
= A – G
= H
Beza kedalaman MH2 & MH3
= Jarak
MH2 & MH3
200 (Gradian Penggalian)
= D
200
= I mm
Kedalaman MH3
= kedalaman MH 1 + beza kedalaman MH2 dan MH3
= B + I
= J mm
IL MH 3 = Aras tanah – Kedalaman MH3
= A – J
= K
Ok semua... selamat mencuba..
