drenaje
El tubo perforado juega un papel esencial en muchas de las aplicaciones de la tubería de polietileno de alta densidad (HDPE). Generalmente, el tubo perforado se utiliza para acelerar la remoción de agua subterránea en suelos o para permitir que el agua pluvial se filtre al suelo. Actualmente se especifican dos clasificaciones de perforaciones en la
especificación de materiales AASHTO para tubos HDPE; Clase I y Clase II. Las perforaciones Clase I, se utilizan comúnmente en combinación de sistemas pluviales/drenaje, mientras Clase II incorpora campos de lixiviación y sistemas de retención/detención. Ambos casos se explican con más detalle en las especificaciones de materiales AASHTO (M294, M252 y MP7). La AASHTO M252 cubre las dimensiones de tubo de 3 – 10 pulgadas (75 – 250 mm), mientras que la M294 cubre las de 12 – 48 pulgadas (300 – 1200 mm). Actualmente, una especificación provisional, MP7 cubre tubos de 54 – 60 pulgadas (1350 – 1500 mm).
APLICACIONES  

DRENAJE TRADICIONAL EN GREENS

The round pipe and fittings are also well suited for drainage of putting greens. Illustrated at right is a typical layout using 4” perforated laterals and 6” solid N-12® pipe installed in
gravel-filled trenches in the subgrade.

Course drainage
Unmanaged storm water results in ponding and mushiness, which damages turf and reduces the number of rounds that can be played. Tee boxes and fairways can be effectively
drained with polyethylene pipe. Smaller diameter, perforated, single wall pipe is used for laterals and local
collection, feeding larger trunks and outlet lines made with N-12® pipe. Nyloplast inline drains and drain basins collect surface water from low spots.

Horizontal Drain Basin (HDB):
A cure for wet bunkers

Sand traps present a special drainage challenge due to periodic clogging of the perforated drain lines. Removing the accumulated silt has been a time-consuming and costly
process. The ADS Horizontal Drain Basin (HDB) is an effective and economical solution to this problem.
The HDB consists of a 12” high x 16” wide x 48” long polyethylene water receptacle covered by a filtration screen sandwiched between two fiberglass grates. It is installed in the subgrade at the lowest point(s) of the bunker. Drainage pipes are tapped into the sides, and an exit drain is installed at the downstream end. The mesh screen helps to keep silts out of the drain water, and greatly extends the cleaning interval. When rejuvenation is needed, simply uncover the unit, remove the grate, flush out the screen and receptacle,
reassemble and re-cover.

CAMPOS DEPORTIVOS

Pipe depth

Most athletic fields have uniformly structured soils in the root zone, which drain relatively quickly. The depth of the pipe is primarily determined by the permeability of the surrounding soil, and the inches of water that need to be removed in a 24-hour period.
Turf grass root zones are fairly shallow, and drainage for most athletic fields is needed in only the top foot of soil. This, plus rapid water removal requirements, dictates a drain depth of one to two feet. However, in areas where salinization may be a problem, a deeper drain depth may be warranted. Many times, particularly in stadiums, a 6” to 8” soil/sand mix is imported to the site. This soil is usually of higher permeability than the existing subgrade, which can be compacted up to 95%. Because the imported soil does drain quickly, it is important to position the drainage lines close to the soil mixture in order to accept and carry the water away to an outlet. Pipe should never be covered with an impermeable layer of soil.

Turf aeration equipment should also be considered. Some aeration tines can penetrate to a depth of 9”, which could damage the buried pipe.

Water removal rate
Professional sports stadiums, particularly those subject to frequent heavy rainfall, may call for several inches per hour of water removal, while for most other venues, a removal rate of a half-inch per hour would be adequate.
If we know the playing field dimensions, the desired water removal rate, and the space between 4” lateral drain lines, we can calculate the water removal rate needed for each
line as follows:

Given:
Area of football field = 160 ft. x 360 ft. = 57,600 sq. ft. = 1.32 acres
Desired water removal rate = 12” in 24 hrs = 288 GPM per acre
4” lateral drain pipe = 10 lines, each 360 ft. long, 16 feet apart
Then:
Area drained by each pipe = 16 ft. x 360 ft. = 5,760 sq. ft. = .132 acres
Removal rate for entire field = 288 GPM x 1.32 acres = 380 GPM
Removal rate per line of pipe = 380 GPM ÷ 10 lines = 38 GPM per line
