Shoring is a form of temporary support propped up during construction or repairs of a building due to its inability to support itself. The primary purpose is to prevent the building from collapsing since it can not accommodate its weight. Also, it is applicable in excavations to prevent the soil form overturning, which would result in a considerable interference of the ongoing project. In both areas, shoring reinforces to allow for the project to complete without mishappenings. There are several shoring methods, and the engineer has to assess the situation to know which one is ideal. Read on to find more about the different types.
Tangent Pile Shoring.
Tangent pile shoring comprises piles of soil placed in a position where the bases are almost touching each other. It is a standard method used in areas where there is minimal water pressure. It is ideal for clay soil since it has high retention levels for fills. The technique is not suitable for places with water as it would find its way in the ground and up the soil hence breaking apart the piles. However, if you prefer this method, you should set in place dewatering mechanisms.
H Or I Shoring.
It is the most common type of shoring method and also called soldier pile walls. To make this kind of shoring, you have to drill a steel pipe in the soil in an I or H form. Additionally, support the earth with a concrete wall between the beams. This shoring’s primary purpose is to offer reinforcement to excavation with a depth ranging from 1.2 meters to 6 meters. Nevertheless, the measurement can exceed as long as the design of the pit supports the load.
Sheet Pile Shoring.
The name comes about since the walls are flat like sheets. It is more or less similar to soldier shoring, but the uses are unique. Construction of the walls happens by driving a prefabricated sheet of steel into the ground to form either a Z or U shape. The layers run from one end to another but connect on every place where there is a corner. This method is vital in the retention of soil during excavation, especially when there is a need for isolation from a water body. It is ideal in ports or harbors. The sheets run deep in the ground to eliminate any chance of seepage, which in return leads to draining of the soil.
Secant Pile Shoring.
Secant pile shoring involves the construction of two piles in an intersecting position. The interlock then forms a wall to support the load. It can come out in two ways, a secondary reinforced pile, or a primary unreinforced pile. Before settling on any, you have to evaluate the situation in terms of drainage and soil type. Secant pile is ideal for areas with closed excavation designs due to lack of sufficient storage space. However, before installation, you have to take the surcharge load into account since the structure is close.
It is the last option for any project when the mentioned above methods don’t seem suitable. Construction of the walls should get tailored to suit the load that requires resistance. Such an approach makes it convenient as there are no chances of inaccuracies. The production material for the walls is reinforced concrete, thus can be used permanently or temporarily. It suits excavations located in dark areas like basements or tunnels.
The list of shoring methods is endless, but the above mentioned are applicable in various construction sites. Building and repairs is a tedious job that requires planning; otherwise, the situation can become unfortunate, leading to time wastage and losses.
