Construction process of railway continuous beam arch bridge, arch springing and prestressed girder
The embodiment of the invention provides a construction process of a railway continuous beam arch bridge passing through a beam transporting vehicle, an arch springing and a prestressed girder. The construction process comprises the following steps: pouring the prestressed girder and arch springing lower bases, wherein the arch springing lower bases are the lower parts in the arch springing, the arch springing lower bases are lower than an edge wing at the top of a simply supported box girder when a girder transporting vehicle transports the simply supported box girder on the prestressed girder, the arch springing lower base is oppositely arranged in the width direction of the prestressed girder, and the arch springing is used for connecting the prestressed girder and an arch rib in the continuous beam arch bridge; and driving the girder transporting vehicle carrying the simply supported box girder to a preset position from the position between the arch springing lower bases, wherein abox body of the girder transporting vehicle and a box body of the simply supported box girder pass through the space between the arch springing lower bases, and an edge wing of the simply supported box girder passes through the space above the arch springing lower bases. According to the embodiment of the invention, the technical problem that the engineering quantity is huge due to the fact thata traditional construction process of the railway continuous beam arch bridge solves the problem that the girder transporting vehicle passes through is solved.
本申请实施例提供了一种通过运梁车的铁路连续梁拱桥的施工工艺，拱脚及预应力主梁。施工工艺，包括：浇筑预应力主梁和拱脚下基座；其中，拱脚下基座是拱脚中的下部分，拱脚下基座低于运梁车在预应力主梁之上运送简支箱梁时简支箱梁顶部的缘翼，拱脚下基座在预应力主梁的宽度方向相对设置，所述拱脚用于连接连续梁拱桥中的预应力主梁和拱肋；将运载有简支箱梁的运梁车从拱脚下基座之间行驶至预设位置；其中，运梁车和简支箱梁的箱体从拱脚下基座之间通过，简支箱梁的缘翼从拱脚下基座上方的空间通过。本申请实施例解决了传统的铁路连续梁拱桥的施工工艺为解决运梁车通过的问题，导致工程量巨大的技术问题。
