India Vertical Band Drains and Soil Stabilisation Methods

  A network of vertical band drains is used to control ground water levels. The draining system uses wicking material, which is supplied in 280-metre rolls. The material is then threaded through a mandrel on a specially-adapted crawler rig. The mandrel then threads the lance and is connected to a slotted anchor plate at the foot of the lance. The lance is then pushed into the silt, which overlies the sandstone aquifer. Vertical band drains are particularly effective for soft clay because they increase the shear strength of the soil. In one study, an embankment raised on 1.5 m spacing and stabilized with vertical band drains showed 90 percent consolidation after 430 days. The embankment was also reinforced with granular piles, which increased the slope stability safety factor by as much as 25 percent. The design of vertical band drains is dependent on a number of parameters. These parameters include the width-to-thickness ratio, the surface area per unit length, and the sp

Soil Improvement Methods Used in the Construction Industry

  A wide range of soil improvement methods is used in the construction industry, ranging from the installation of drainage to the construction of soil-stabilized structures. Soil stabilization is achieved through the use of various techniques, including blending two or more soils, adding chemical additives, and excavating the existing soil. The goal of soil stabilization is to increase the properties of soil and increase its response to loading. This results in stronger, more stable soils and allows for more efficient construction and reduced environmental impact. A variety of ground improvement methods are available, but there are two primary methods for modifying soil: surcharging and overexcavation. Surcharging involves a large volume of water being placed in the ground to increase its density. The process is time-dependent and, depending on the soil type, can prolong a construction project. This method is suitable for soft clay and organic silt. Another method of soi

Indonesia Soil Consolidation Companies and Soil Stabilisation Methods

  Soil consolidation is an incidental process that requires no special equipment to complete. While soil consolidation is not a necessary part of building construction, it is important to understand its potential to help mitigate future foundation problems. These problems can manifest themselves in a variety of ways, including cracked facades, uneven slabs, and damage to utilities. In order to mitigate such problems, it is important to measure the amount of consolidation that is present in the soil and the amount that could be used to create a stronger foundation. To understand the process of soil consolidation, it helps to understand the physics behind the process. Basically, consolidation involves removing stress and then reinforcing it. This recompression process causes the soil to rebound and consolidate along a recompression curve. This recompression curve is described by an index called the recompression index. This index represents the gradient of the compression a

Madagascar Prefabricated Drains and Soil Stabilisation Methods

  A significant difference between prefabricated drains and conventional pipe drains is their structure. Prefabricated drains usually have a plastic core, a filter sleeve, and a system of vertical channels. In contrast, pipes are usually made of a single material. The width of the Colbond drain is substantially larger and its permeability boundary is lower than that of a conventional pipe drain. Prefabricated drains in Madagascar were first introduced to geotechnical engineering in the early 1930s. The first one on the market was the Kjeilman card'board wick, which consisted of two cardboard strips with ten longitudinal grooves. It was installed using a special machine. Prefabricated drains are very efficient and can speed up the consolidation process. Prefabricated drains are often used in soft ground improvement projects. They contain a plastic core and geotextile that acts as a filter. They are available in a variety of sizes and are designed for specific conditions
