In terms of drainage network, then in accordance with the functions and the system works, channel types can be distinguished:
A. Channel interceptor (Interceptor Drain)
Interceptor drain channel is a channel that serves as a deterrent to the imposition of the flow from one area to another area underneath. These channels are amazingly constructed and placed on the relatively parallel to contour lines. Outlet from this channel are common to the collector channels, conveyors or directly in the natural drainage channels.
B. Channels Gatherers (Collector Drain)
Collector channel is a channel that serves as a collector discharge of drainage channels smaller and will eventually discharged into the conveyor channel (bearer).
C. Line Carrier (Conveyor Drain)
Conveyor channel is a channel that serves as a carrier of waste water from an area to the disposal site without having to jeopardize the region traversed. Lelak conveyor line at the lowest part of the valley area. so that it can effectively function as collecting tributary of existing channels. As conton is a channel flood diversion channel or channels or by-pass which works exclusively drain water quickly to the disposal site.
In another sense, this channel is different from the underground drainage. In this case the ingress of water through the soil infiltration by gravity into the holes contained in drainage channels are planted in the ground. In fact there is a channel can work at once to the second or even third type of the function.
Procedure Design Layout System Drainage Network
By looking at topographic maps, we can determine the direction of flow which is the natural drainage system that is formed naturally, and can determine the length tolerance of inundation of the area plan. Information situation and physical condition of the land, both current conditions, and planned to note, among others:
- Existing network systems (drainage, irrigation, electricity, etc.).
- Bottlenecks that may exist.
- Ownership boundaries.
- The location and number of existing infrastructure.
- Level requirement necessary drainage.
- Overview outlines priority areas.
All of the foregoing is intended to be in the preparation of the layout of the drainage network system is not a conflict of interest. In determining the layout of the drainage network aims to achieve the following objectives, namely:
- Drainage network system can function according to the destination (target).
- Pressing the negative environmental impact as small as possible.
- Can last a long time in terms of construction and function.
- The construction costs as low as possible.
To ensure the good functioning of drainage channels will require complementary buildings in certain places. Type of complementary buildings in question include:
(A) Building a cross, eg culverts.
(B) building energy solvers, such as buildings waterfalls and steep channels.
(C) Building seat erosion, for example, ground sill.
(D) Building inlet eg, side grill / flat.
(E) Building outlet for example, diving pool water
(F) Building floodgates, eg sliding door, the door atomatis.
(G) the pump house building
(H) Building a pool collector.
(I) Building control aperture (man holes)
All the buildings of the above does not always have to be on every network drainage. Existence depending on local needs that are usually affected by the channel functions, environmental conditions and the demands of network perfection.
