ESC TRENCH SAFETY SOLUTIONS - Trench Box Manufacturer
A 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.

Dewatering Methods for Excavations at Construction Sites
Deep 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.

Braced Excavations - Struts - Cross Lot - DeepExcavation
A 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
