Question

Throughout concreting of diaphragm walls, three tremie pipes are used in single time. But, only one concrete truck is obtainable. How have to concreting works been approved out?


Answer

Most ideal state is to supply each tremie pipe with a single concrete truck. Though, if in case only one concrete truck is obtainable, all fresh concrete in truck have to not be placed in one single tremie pipe. With all fresh concrete located in one single tremie pipe while others left void, then because huge provider of concrete to tremie pipe, a little concrete hump may form at base of tremie pipe and it is likely that it might collapse and trap the slurry inside diaphragm walls. Therefore, fresh concrete have to be consistently shared among tremie pipes to keep away from such incidence.
