| Steel Mortar Composite Foundation
Thousands of transmission line towers all over Indonesia stand on Steel Mortar Composite Foundations (SMCF). While they differ in dimension and size, they have one thing in common:
They are all made with BSM owned equipment.
PT. BSM is proud to be the only company in Indonesia owning SMCF equipment.
How it works
The Steel Mortar Composite Foundation (SMCF) comprises an “H” beam with a welded driving shoe at its base. A powerful hammer is then driving the H beam into the soil. While driving the H beam into the soil, mortar is introduced under pressure through pipes connected directly to the pile base. The mortar fills the hole formed by the driving shoe and, being of higher density than the surrounding soils restricts the ingress of ground water and minimizes the possibility of the soil wall collapsing into the hole formed by the driving shoe. The mortar also provides an anti-corrosion cover to the “H” beam and transmits the pile forces into the surrounding soils.
Advantages
Comparing SMCF with conventional foundation types, SMCF reveals great advantages:
- Significant time savings
- Significant cost savings
- Reduced logistic efforts
- Reduced complexity
- Compatible with soft soils (> soil class 3)
Success Story
Due to its advantages, SMCF is frequently used in many countries and especially in Indonesia. Especially in soft soils (soil class >3), SMCF is almost without alternative. Thus, in swampy soils or in rice paddies, as found throughout Indonesia, SMCF plays a major role. Many projects have already been realized in Sumatra, Kalimantan and Jawa.
The following list only contains a few of projects with SMC foundations in Indonesian:
- UNGARAN – KRIAN (500 kV)
- GRESIK – KRIAN – PAITON (500 kV)
- CIRATA – CIBATU (500 kV)
- CILEGON – CIBINONG – SAGULING (500 kV)
- CIBINONG – BEKASI (500 kV)
- KLATEN – TASIKMALAYA (500 kV)
- LAHAT – LUBUK LINGGAU – BANGKO – MUARA BUNGO (275 kV)
- PAYAGELI – BINJAI – P- BRANDAN – LANGSA (150 kV)
- KISARAN – P. PRAPAT (150 kV)
- TANJUNG PRIUK – PULOGADUNG (150 kV)
- PALARAN SAMBUTAN (150 kV)
- MARIANA – KAYU AGUNG (150 kV)
Next Steps
If you are facing challenges when it comes to soft or even flooded soils, SMCF is your solution and we look forward to your inquiry.
Of course, we also look forward to hearing from you in case there are open questions regarding Steel Mortar Composite Foundations.
