Precautions in Timbering
In the case of deep excavation, timbering process takes an important role. It provides temporary support to the collapsible sides of the trench. Failure of timbering can lead to a serious accident, and should therefore be entrusted to very experienced hands. It may also affect the stability of the adjoining properties. Following precautions should be taken care of while timbering.
1. Slip of The Earth
One should keep eye on tendency of the soil to slip. In general, cracks are formed on the ground before the actual slip of soil takes place. In other words, the formation of cracks on the ground is acts as an indicator of the possibility of soil slipping. Therefore, any formation of crack on the ground should carefully be inspected and, if possible, sufficient measures should be taken to keep the soil from slipping.
2. Traffic
The movement of heavily loaded vehicles like truck, wagons, etc., and other mechanical equipments should not be allowed too close to the trench.
3. Safety of Adjoining Structure
If the adjacent structure does not seem safe due to deep excavation, temporary support should be provided to the structure with the help of shores.
4. Ladders
The ladder should be provided at a suitable intervals as these help the staff to get out from the trenches during any accident. In case of very poor soil, the spacing between two ladders should be around 15 m. But, in case of good soil it may be more than 15 m.
