Provide engineering solutions. By Prof. Dr. Amorn Pimanmas, President of the Structural Engineers Association of Thailand From the incident of the temporary manhole cover collapsing. Causing a 10-wheel truck to fall into a conduit pit on November 8th. Prof. Dr. Amorn Pimanmat, President of the Structural Engineers Association of Thailand, explained that it was a failure of the concrete cover slab that was placed on the manhole of the electrical wire pipe. which is considered a temporary structure It will be opened for work during the night. and close the lid for daytime traffic.
As for the assumption of the cause of the failure of the manhole cover. It was formed from a steel beam which was the supporting structure for the disaster pit cover. There are 3 factors that may be the cause: truck weight That is more than what is required by law. which is for a Email Data ten-wheel truck The law specifies that the load should not exceed 25 tons. It will cause damage to the road. Structure supporting the well cover It is a steel I beam. And deformed steel bars are used as stiffeners on the sides of the beams. You must check how much weight the steel beams can support.
And the use of deformed bars as chevrons attached to the sides of the beams. Does it meet the standards? Work steps and use of steel beams Which position is placed during closing and opening the pond cover? and the movement of the well cover as the vehicle moves past. This may cause the steel beam to move out of position. or caused by the misalignment of the action force It may cause the steel beam to twist. and causing the pond cover to lose its support point and collapsed following it Even though the analysis framework has been laid out in the above 3 points.
