Chapter 14 – AutoCAD Civil 3D 2013 Essentials – The Essentials and Beyond

hello this is Eric Chappell author of
autocad civil3d 2013 essentials and this
is the additional exercise for chapter
14 and this exercise we're going to
continue the design of the storm system
so in the previous exercises you develop
the storm system for the northern part
of Jordan court and now we're going to
look at the remainder of the roads
Madison Lane and Logan Court and the
rest of Jordan court and creating inlets
and pipes for for that part of the
system we basically have two isolated
systems we have this front area that
drains out to the road and then we have
this back section that's going to drain
through through a drainage easement here
ultimately into the stream or possibly
into a detention area so we've got a
list of parameters that we need to
adhere to the first one says that all
pipe should lead to the South inlet at
station 17 plus seventeen point three
four that's right here this one so
everything is going to funnel into this
location this is the low point and then
there's going to be a 36 inch pipe that
goes from that Inlet through the
drainage easement into the into the open
area back here so I'm going to start by
creating the inlets in a way to match
what we've done in previous chapters so
to get started I'll go to the Home tab
of the ribbon and we'll say pipe network
pipe network creation tools we're going
to create a new network I'm gonna call
it storm to make sure our parts list is
set to storm sewer our surface will be
the road finished ground and for now
let's do inlets along Jordan Court so
that's the stationing most of our pipes
and structures are let's say half of
them are going to reference Jordan
courts so that's what we'll set is the
alignment that's default for this pipe
network but as you learned in previous
chapter previous parts of this chapter
you can assign a different alignment to
any pipe or structure anytime you want
so click OK that brings up my tool bar
and I'm going to put that over here and
I'm going to set this to curb inlet and
then choose the structures only tool and
I'm just going to play structures at the
Centers of these circles all right so
these are just going to be inlets not
gonna worry about their rotation for now
we'll fix them in a moment
now these inlets will reference the
Jordan Court alignment even though
they're a long Madison Lane no problem
we can change them later on
and I think that takes care of all of
the inlets if I missed any we can add
them later so now that the inlets are in
place I'm going to spend a little time
getting them oriented properly and one
of the nice things about having the
inlets across the road from each other
is that you can you can leverage the
grips and align them pretty quickly just
like this now obviously if they're not
perpendicular to each other that little
trick is not going to work but a lot of
times they are so it works out very
nicely
now I'm pretty sure we're going to need
some manholes as well but we really
don't know where those are gonna be just
yet so we're going to ignore them for
now and just start with the inlets
okay so that gets the inlets in place
and now they're all oriented
perpendicular to the road what I'll do
now is begin connecting these inlets
with pipes so if you remember our one of
our parameters was that the pipes
furthest upstream should be 15 inches so
I'm going to set my default pipe size or
my current pipe size to 15 inches and
I'm gonna use the pipes only command and
I'm just going to play a little game and
connect the dots here I'm watching for
the glyph which tells me the little
yellow symbol that tells me that the
pipe is connecting to the structure and
we'll say that's a 15 inch pipe and also
this one now without a hydraulic
analysis we don't really know if 15 is
an adequate size for that we're going to
assume that it is and that now we have
to jump to 18 inch so we're going to
make some assumptions about the pipe
size as we need here that's okay for our
purposes I'm going to switch this to 24
inch again when you do this you can
choose whatever pipe sizes you want just
make sure that as you work downstream
that the pipes get larger it can't flow
from our larger pipe into a smaller one
now I'm going to skip right across to
this one and then across the road with a
30 inch pipe and then I'm going to
change my structure to a head wall for a
36 inch pipe and change my pipe size to
36 inches and I'll jump right across
here and provide my 36 inch pipe with
the N wall now what I forgot to do was
to choose the pipes and structures
command so now I'm going to go to
structures only and and drop that
structure now what I did is I clicked
off of it a little bit so I kind of
missed the end of the pipe no problem
I'm going to say connect part
gonna connect it to that part right
there you saw the pipe move over and now
I can take the structure and move it as
well so I'm kind of centered through
that that easement a little better all
right so now we've got this little guy
to worry about well since this is an
upstream leg this pipe right here can be
15 inches so I'm going to change my pipe
size back to 15 inches and I'll use the
pipes only command and just connect from
there to there and again the reason this
pipe can be just 15 inches is because
the water that's entering that pipe is
only being collected by one Inlet where
as this this pipe here is conveying the
flow of several inlets upstream so it's
going to be seeing a lot more flow
probably so that takes care of the
connections of the pipes and we'll move
on to the next step which is adding some
manholes
so to do that I'm going to change my
structure to a cylindrical Junction
structure storm manhole and I'll switch
this to structures only and I see two
spots that are kind of glaring that I
need I'm cutting right through you know
probably right under someone's house
that I need to bend the pipe run and get
it in the right of way and a third one
right here it looks like I need one here
as well so what I'll do is just drop a
manhole about about right there I'll
drop a manhole about right here I can
move it around once it's in and I'll
also put one here and then I can click
that manhole move it inward again we're
trying to get that pipe into the right
away so if I need to sneak it out on the
road a little bit that's usually okay
it's better to have the pipe on the road
than to have it crossing within
somebody's property for this one we can
maybe pull that out there
that's looking pretty good and for this
guy we'll pull it over here and we can
probably move that one out to the
right-of-way no we still have a little
bit of a problem right there so I think
we're just going to place this one out
in the road and that takes care of
keeping all the pipes in the
right-of-way and then the last thing we
need to do is to show all of these pipes
and structures in their respective
profile so I'll start with Jordan court
and since these are right across from
each other I'm just going to pick one of
them so I'll pick that structure that
pipe that manhole working on down the
line and I'll stop with that with that
structure right there and I'll say draw
parts in profile to find my Jordan court
profile view which is this one so there
we have those pipes and structures next
I'll do Madison lane so for Madison lane
I'll do this structure this pipe this
manhole working our way down this
structure right here again draw in
profile
this time I'll pick the Madison Lane
profile you can see we've already got
some sanitary shown in that profile and
then finally Logan Court will choose
this one this one
and this manhole
and that takes care of showing the pipes
and structures in profile view and that
satisfies all of their requirements for
our additional exercise and completes
all of our tasks for the additional
exercise of chapter 14
