While it is not all uncommon to encounter jobs that require both vibrating and screeding concrete on a slope, it is quite unusual to find these two operations being performed simultaneously with the same piece of equipment. This feat has been accomplished with good success and economy on a 8 inch thick concrete flood wall slab recently constructed at Bradford, Pennsylvania. The concrete was placed by bucket to the approximate height of the forms. When an entire 15 foot wide by 18 foot high section had been covered with the stiff mix, the screed engines were stared up at the bottom of the slab. The screed was then slowly pulled up the face of the concrete by means of the winch cable which was attached to an eyebolt in the center of the screed beam. The tow truck was normally operated on the top of the bank, but when there was insufficient room for this a sheave was provided at the top to permit the truck to operate below the bank. Moving on rollers which engaged the side forms, the vibrating screed moved slowly up the embankment, both striking off and consolidating the concrete as it passed. It was found that under favorable conditions only one pass was required to obtain a satisfactory finish. Although on rare occasions the appearance of concrete bulges behind the screed made it necessary to make a second pass, even with these delays it was found that the average time for striking off and vibrating each section of the concrete was only a little over a minute. Upon the completion of each pass, the vibrating screed was attached by the eyebolt to the cable on a crane and lifted to the bottom of the adjoining section of floodwall. The final finish of the slab was obtained by means of hand troweling.
