10. Flattening Pressure Endurance Ratio
Flexible Permeable Hose with the screw like reinforcement structure is constructed by using the strong
carbon steel wire which is to let external pressure to spread evenly around the body of the hose when press.
1.The list of pressure added with tolerence of +5%.
2.The test results is based on 25cm hose length,if testing length is 1 meter, then the pressure added will be 4 times of
this listed test results.
The test results is 1 meter.

12. Methods of Installation
Flexibility, lightweight and easy to install cost effective.
。
Geotextiles is not required, for wrap-around the pipes.
No fittings is required for jointings (i.e.T-joints, Y-joints or elbows)
。
(We fabricate bends, tees, elbows reducer by using the parent hose.)
The hose can be installed horizontally, vertically, diagonally or in
herringbone design or 90
。
or any other way the client wishes to
install.

Sub-Soil Drainage Technology At Its Best
Static Pressure of Ground
The static pressure of ground above the buried
pipe can be counted pre following formula:
P: Static pressure of ground (kg/m2)
h: the burying depth
B: the width of ditch
W: the weight of 1 m3 soil (2000kg/m3,soil and
rock)
Ө: 40ﾟ (the angle of ____ ) (May adjust)
e: the base of _____ (May adjust)
B: Pipe diameter (D)X2
18. Typical Trench Details
Recommendation I :
- Road Base
Drainage
- Railside Drainage
Recommendation II :
- Concealed Perimeter
Drain
Recommendation III :
- Field Drainage
NOTE:THE BACKFILLING MATERIALS WILL DEPENDS ON.
1.COST BETWEEN AGGREGATE AND SAND.
2.THE RATE OF INFILTRATION, USING AGGREGATE WILL CREATE A BETTER POROUSITY AND WILL
ENHANCE THE PERMEABILITY RATES.
** 回填土溝之材料選擇,將隨著下列因素變更
1.骨材與粗砂的成本。
2.用粗砂會獲得較好的孔隙率,且會增進其滲透率及排水量。
