Method for installing bridge girder erection machine at tunnel portal
The invention discloses a method for installing a bridge girder erection machine at a tunnel portal. The method is used for completing installation and use of the bridge girder erection machine under the condition that the inner space and the outer space of the tunnel portal are limited. The method comprises the steps that a middle supporting leg assembly, a front supporting leg lower cross beam rail, a front supporting leg lower cross beam and a front supporting leg wheel box combination are placed at a tunnel portal; the height of a base supporting cushion of the beam transporting vehicle is adjusted according to the wheel face height of the middle supporting leg assembly, a main beam is hoisted to the beam transporting vehicle, a rear supporting leg is installed at the tail of the main beam, and the main beam is formed by splicing a plurality of main beam sections; the main beam is conveyed to the middle supporting leg assembly at the tunnel portal from the other end of the tunnel through the beam conveying vehicle; a front supporting leg, a front upper cross beam, a rear upper cross beam and a rear support are installed on the main beam, and a balance weight is additionally arranged on the rear section of the main beam; a longitudinal joist barrow and a crown block are mounted on the main beam; and the rear supporting leg is jacked to enable the main beam to move forwards, so that the front supporting leg moves to a pier stud in front of the tunnel portal.
本申请公开了一种隧道口安装架桥机的方法，用于在隧道口内、外空间受限的情况下完成架桥机的安装使用。本申请方法包括：在隧道口安放中支腿总成、前支腿下横梁轨道、前支腿下横梁以及前支腿轮箱组合；根据所述中支腿总成的轮面高度调整运梁车的底座支垫高度，将主梁吊装至所述运梁车上，并将后支腿安装在所述主梁的尾部，所述主梁由若干节主梁段拼接而成；通过所述运梁车将所述主梁从隧道的另一端送至所述隧道口的所述中支腿总成上；在所述主梁上安装前支腿、前后上横梁以及后托，并在所述主梁的后段增加配重；在所述主梁上安装纵行桁车和天车；顶升所述后支腿使所述主梁前移，使得所述前支腿移动至所述隧道口前的墩柱处。
