Beam erecting method for widened bridge erecting machine in ramp area
The invention discloses a ramp area widening bridge erecting machine beam erecting method which comprises the following steps that beam pieces are erected in a segmented mode in the longitudinal bridge direction of a ramp area, the position of a beam erecting machine in the transverse bridge direction in each segment can be adjusted by moving supporting legs at the bottom of the beam erecting machine so that the beam pieces can be erected at different positions in the transverse bridge direction of the segment, and the beam pieces can be erected at different positions in the transverse bridge direction of the segment. A post-cast strip is reserved between the adjacent beam pieces in the same section; and concrete is poured at the post-cast strip, so that the adjacent beam pieces are connected together, and widening of the ramp area is achieved. The method has the advantages that the beam pieces are erected in the longitudinal bridge direction of the ramp area in a sectioned mode, the post-cast strips are reserved between the adjacent beam pieces in the same section, and concrete is poured at the post-cast strips to enable the beam pieces to be connected together, so that widening of the ramp area and weight reduction of the beam pieces are achieved.
本发明公开了一种匝道区加宽架桥机架梁方法，所述方法包括以下步骤：沿匝道区的纵桥向分区段架设梁片，其中，每一区段内均可通过移动架梁机底部的支腿来调整所述架梁机的横桥向位置，以便在区段横桥向的不同位置架设所述梁片，并且同区段相邻所述梁片之间预留有后浇带；在所述后浇带处浇筑混凝土，以使相邻所述梁片连接在一起，实现对所述匝道区的加宽。本发明的优点是：通过沿匝道区纵桥向分区段架设梁片，并在同区段相邻梁片之间预留后浇带，通过在后浇带处浇筑混凝土以使梁片连接在一起，实现了对匝道区的加宽以及对梁片的减重。
