<p>PROBLEM TO BE SOLVED: To reduce underground pipe excavation cost by decreasing the embedding depth to an adequate value because the load of motor vehicle to an underground pipe is considered as a concentrated load if the embedded depth of underground pipe is shallower than 60 cm and conventionally in the underground pipe embedded construction, the embedded pipe is considered as being subjected to a partially uniformly distributed load or an uniformly distributed load thereby embedding the pipe to a deep position in many cases in which the excavation and relevant costs are increased; and if the embedding depth is shallow, the embedded underground pipe is easily affected by the load of motor vehicle. SOLUTION: A load receiving slab 3 having a predetermined area is embedded in earth directly above the embedded underground pipe 2 thereby receiving the load of motor vehicle by the slab 3 and reducing the influential force of the vehicle load to the underground pipe 2.</p> |
