How much do you know about the technological process of an air - shield dam?
5.The concrete is transported by special concrete mixer trucks from the mixing plant, and a concrete truck pump with a boom length of 36m is used for concrete pouring. Before pouring, the construction road from the main road to the working surface should be repaired.
6.The slump of the concrete is 160 - 180mm.
7.The concrete pouring must be carried out continuously, with an intermittent time not exceeding 2 hours.
8.A flat - type vibrator is used for vibrating the cushion layer concrete. After vibrating it densely, workers use a wooden float to level the surface.
9.Concrete curing
(1) Before the initial setting of the concrete after pouring, avoid water accumulation on the silo surface and direct sunlight exposure.
(2) After the final setting of the concrete, use the method of watering for curing or cover it with plastic film.
(3) The concrete curing should be continuous. During the curing period, the surface and all sides of the concrete should always remain moist. The curing time is 28 days.
