Prefabricated vertical drains have become one of the significant techniques to minimize the impacts of liquefaction on buildings. Many vertical drains have been installed in Malaysia to prevent damage to the structures. The effectiveness of the vertical drains is proven by the fact they alleviate the pressure caused by an earthquake.
During the prefabricated vertical drain installation, a depth of 4 to 65 meters can be covered. Moreover, options of customized installation, which includes a variety of options for various soil types and layers, are also present. The components used are one of the strongest for vertical drain installation in Malaysia. Moreover, an experienced and thoroughly professional team is present to make sure the drain is installed correctly.
In order to thoroughly understand the significance of the vertical drains, you should be familiar with the basics of vertical drains and the techniques used in their installation.
Vertical drains, also called the wick drains, are installed to condense the dissipation path of surplus water. They have also used to fast-track the process of consolidation by prefabricated vertical drain (PVD) installation.
The process includes the fitting of drainage paths or vertical drains into the soil. It is made sure that the prefabricated vertical drain used during the installation can withstand high pressure and extreme conditions. They can work in almost any condition and can be catered to a specific location as well.
Certain types of soil, for example, sand, are highly porous. As a result, it can adapt to the pressure quickly, and drain the porewater quite easily and quickly. On the other hand, some soils have poor permeability, for example, clay. Such types of soils resist the compression, and the dissipation of the pore water is very slow in this scenario.
Therefore, the process of reducing the excess pore pressures, also called the process of consolidation can be very slow on low permeability soils. Vertical drains are used in such cases to enhance consolidation.
The primary reason for using a vertical drain is to fasten the consolidation process. Reduced time of consolidation helps in accelerating the usual construction timeline. Moreover, vertical pipes help in regulating residual settlements. Various studies prove that the subsoil is solidified appropriately with a good consolidation process, supported by the vertical drains.
Some of the best vertical drain installation services are available in Malaysia. Through these services, people can get the following benefits to reduce the total time needed for consolidation and intensify the strength rate by the consolidation of stable soft soil.
Vertical drains have applications in numerous areas of Malaysia. Some of these sectors are:
The installation of the prefabricated vertical drain is done very cautiously. The service and the parts used are approved through the concerned authorities and posses long-lasting effects.
PVDs are fitted through steel around the material from which vertical drain is made. The hollow mandrel is put in the ground using different stitchers. Static, as well as vibrating options, are present, depending on the type of the surface in which PVD is to be installed.
Once the mandrel has reached an appropriate depth, it is pulled back so that the drain can be cut. Sometimes, a problem may arise in pulling back the mandrel. In that case, predrilling is performed by an experienced team.
The depth and width of the PVD installation are determined after thorough research. Many factors, such as the type of the soil and consolidation margin, are considered while deciding a definite depth to which the vertical drain is to be installed.
