Design and Construction of Deep Excavations
Get a quoteA trench box is therefore ideal for quick-phased and long-term construction projects. Worker protection . Trenching and excavation work can be very dangerous, as trench collapses can occur even if safety precautions are strictly followed. It is, therefore, a good idea to add an extra layer of protection to ensure worker safety on such projects.

Get a quoteDiaphragm walls are ideal for lateral earth support for deep excavations as well as forming a cut off wall, and are often incorporated as the permanent building basement walls. This can create project savings by eliminating the need for temporary earth support and dewatering.
Get a quoteDeep Well Method of Dewatering Excavations Just like the wellpoint method, wells are drilled around the excavated area, but the diameter of wells, in this case, varies between 150-200mm. By creating deep wells around the vicinity, the groundwater is made to fall into them under the influence of gravity.
Get a quoteJan 15, 2021 · With the increasing exploitation and utilization of underground spaces, the excavation of deep foundation pits adjacent to existing metro tunnels is becoming increasingly common. These excavations have the potential to cause safety problems for the operation of the nearby metro. Therefore, to prevent metro tunnel accidents from occurring during the …
Get a quoteA typical sequence of excavation in cross-lot braced excavations is shown in Figure 1. The struts rest on a series of wale beams that distribute the strut load to the diaphragm wall. Pre-loading ensures a rigid contact between interacting members and is accomplished by inserting a hydraulic jack as each side of an individual pipe strut between
Get a quoteWhen it comes to excavations for major projects, particularly in densely developed urban areas, there are more options than just the conventional bottom-up building approach writes geotechnical specialist John Endicott. While just about every major construction project involves digging large holes in the ground, the methods of excavation can have a significant impact on …
