ROWD Sled Data

Structural Calculations

The ROWD mobile dewatering sled is an alternative to conventional dewatering structures that are stationary. To determine the limits of the structural design an analysis of the critical components was performed. The structural analysis included evaluation of; the controlling vertical members, locking plate, and securing pins. In addition, 3D analysis of the long side gates, as a complete system, was conducted. For analysis the loading condition of the ROWD sled was evaluated completely full of water. Each structural component was observed to be within allowable stresses for A36 steel using ASD design methodology under the loading condition. Results indicate a minimum factor of safety equal to 1.5. The ROWD sled is safe to operate under conditions that are less than or equal to the extreme loading condition. Furthermore, these results are applicable regardless of ambient conditions the dewatering sled is exposed to.

ROWD SLED FLOW TEST

Flow tests were performed on 2 degree and 5 degree slopes with a 3-inch trash pump and a 6-inch trash pump. The purpose of this test was to try and identify the max flow rate of a standard size ROWD sled on different slopes.
