Problems solved by technology

[0017] 1. Two sets of buckle systems are required, which are costly
[0018] 2. Using two sets of buckle cable systems, the installation process is more complicated and may interfere with each other, affecting the progress of the project
[0019] 3. If the two sets of buckle cables are fixed with the same ground anchor, the force of the ground anchor is calculated according to the force exerted by the two rib arches connected by the two sets of buckle cables. anchor cost
If two sets of buckle cables are connected to different ground anchors, a new ground anchor needs to be added, which also increases the engineering cost

Embodiment Construction

[0047] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0048] Examples such as figure 1 , 2 Shown: a box arch bridge installation method, including the following steps:

[0049] (1) Excavate the earthwork of the main arch abutment and install the cable system;

[0050] (2) Pouring the main arch abutment concrete and arch section;

[0051] (3), hoisting of arch section

[0052] (4) Bent rack installation on the arch

[0053] (5), T beam installation

[0054] (6), Bridge Deck Construction

[0055] In the hoisting of the arch section, the cast arch section is hoisted in place by a cable system, wherein the installation of the arch section adopts single ribs to close together to form an arch ring, and the specific steps are as follows:

[0056] (1), use the cable system to hoist the first arch section 1 in place, hang the first arch section 1 through the left buckle cable 2, and buckle the first wind cable 3 t...

Abstract

The invention discloses a method for mounting a box arch bridge. The method comprises the following steps: (1) excavating earth and stone work of a main arch abutment, and mounting a cable system; (2) pouring concrete of the main arch abutment and haunch; (3) hoisting the haunch; (4) mounting a bent on the arch; (5) mounting a T beam; and (6) constructing a bridge floor system. In haunch hoisting, after a first arch rib is mounted, a knotted rope used for stabilizing the haunch is detached, and the knotted rope is used for mounting a second haunch, and the like, so that all haunches can be mounted by the first knotted rope. The method simplifies mounting program of the box arch bridge, and greatly saves construction cost.

Description

technical field [0001] The invention belongs to the technical field of bridge construction methods, and in particular relates to a box-shaped arch bridge installation method. Background technique [0002] At present, the installation of box arch bridges is mainly completed in the following steps: [0003] (1) Excavate the earthwork of the main arch abutment and install the cable system; [0004] (2) Pouring the main arch abutment concrete and arch section; [0005] (3), hoisting of arch section [0006] (4) Bent rack installation on the arch [0007] (5), T beam installation [0008] (6), Bridge Deck Construction [0009] In the hoisting of the arch section, the cast arch section is hoisted in place by a cable system, wherein the installation of the arch section adopts single ribs to close together to form an arch ring, and the specific steps are as follows: [0010] (1), use the cable system to hoist the first arch section 1 in place, hang the first arch section 1 thr...
