Peat Soil Improvement Method Using Woven Bamboo and Cerucuk

Abstract

Most of the land in South Sumatera is the problematic soil, one of that is peat. Peat has low soil bearing capacity, and it becomes a problem when construction is built. Before the installation process, it is necessary to handle that soil. Soil improvement that can be done on peat to increase the bearing capacity value is the reinforcement method or physical stabilization. The results of research on woven bamboo and cerucuk are used as reinforcement material, which is expected to be an alternative to improve soil bearing capacity. The research methodology used was on the scale of the laboratory and analyzed by comparing the soil bearing capacity without reinforcement in bearing capacity ratio (BCR). The maximum bearing capacity with cerucuk reinforcement and without woven bamboo is 39.33 kPa with variations of the two outer rods of the left and right sides from 750 angle toward the foundation plane. However, using the 3 layers of reinforcement woven bamboo that is combined with cerucuk, which has diameter 1,5 cm and length 60 cm generates the highest soil bearing capacity value. The maximum of bearing capacity is 58 kPa. The BCR is 10,88 or in percentage is 988,2%, or 10 times greater than bearing capacity without reinforcement. So, it can be inferred that woven bamboo and cerucuk are used as an alternative to improve bearing capacity on peat soil.

Gelam Wood (Melaleuca cajuputi Powell) as a Substructure Construction Material

“…Reinforcement with gelam wood pile combined with 3 layers of woven bamboo itself was able to increase the bearing capacity of the soil up to almost 10 times the condition without woven bamboo reinforcement. This shows that the use of gelam wood pile, either with woven bamboo or not, is able to increase the bearing capacity of the foundation on peat soil [12].…”

Settlement Performance of Bamboo Dendrocalamus Asper for Improving Peat Soil Reinforcement Stability

“…The techniques are based on peat depth categories. Some studies have shown that the researchers have highlighted several techniques such as excavating, replacement, sand drain, lightweight fills, and stone columns [10]. In the current situation where the population of residents is increasing every year, need constructions player to identify alternative ways, and proper methods are needed to avoid the instability of the foundation structure caused by peat settlement [11].…”
