箱梁浇筑顺序图(国外英文资料) The concrete enters and vibrates 4.3.1 after the inspection of the steel bar and the template, the concrete is poured, the concrete is mixed, and the truck is carried to the cast-in-place. The entry mode of concrete is as follows: Floor: the concrete is carried by a portable vibrator in the interstitial space between the inner and outer membrane. Abdominal plate: the concrete is placed in the interstitial space between the inner and outer membrane. Roof: directly cast on the top plate 4.3.2 precast box girder concrete pouring from one end of the beam to the other end of the oblique layered each layer according to 30 cm casting, for casting to reverse casting when 1/4 span length, and closed the 1/4 span. The casting sequence is poured into the board and the roof concrete. The concrete of the bottom plate is laid in parallel, and the concrete of the concrete after the concrete of the bottom plate is fully vibrated, and the concrete of the roof is cast. The thickness of each layer is no more than 30cm. The concrete casting sequence is shown below Concrete casting profile Concrete casting facade 4.3.3 concrete vibrates The concrete vibrates in the way of artificial vibratory and mechanical vibratory. The insert vibrator is not allowed to vibrate steel beam anchor plate, not to be able to impact the steel reinforcement and vibration of the steel bar, etc. The steel beam is close to the template and the reinforced area of the anchor plate, which is to be used with the method of vibration. The ground plate is vibrating with vibratory rods, and then the sealing plate and the top of the back plate are sealed after the concrete is sealed. Web use 30 mm immersion vibrator, adherent vibrator support ascending bubbles way layered vibrating, layered thickness is less than 30 cm, attached type vibrator vibrating time control between 10 ~ 15 seconds, and shock vibration intensity is weak earthquake ~, adherent vibrator may not open strong earthquake.
