Is it safe to have a concrete trench without a corbel carrying the 250mm thick pre-cast concrete cover? (road crossing)
trench = 250mm thick x 1100mm width edge to edge distance
(depth is 1000mm)
pre-cast cover = 800mm x 1m strip
concrete cover are placed within 1100mm trench, those only 100mm are carrying the concrete slab plus the vehicles passing the trench.
pls help me guys, i am a novice in the field of structural designing...tnx
