Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building construction technology, especially relates to a mobile hopper for bridge concrete retaining wall pouring. BACKGROUND

[0002] When pouring the concrete retaining wall on both sides of the bridge, the transition between the concrete pouring equipment and the retaining wall formwork needs to be realized through the hopper. One end of the hopper is directly lapped on the formwork, and the other end is fixed and supported through the support frame. In actual construction, the retaining wall formwork needs to be fixed through the tensioning bolt. In order to avoid the bolt hole on the upper part of the retaining wall after pouring, the tensioning bolt above the retaining wall formwork is generally arranged above the formwork through the outside support column, so that the hole in the poured retaining wall can be avoided. Therefore, when the hopper is poured at other positions through the upper tensioning bolt, the hopper needs to be separated from the formwork first, and then the tensioning bolt is bypassed from the outside of the formwork, which is very inconvenient.
