Method for in-place installation of water supply pipeline in lower belly of bridge

Abstract

The invention discloses an in-place mounting method for a water supply pipeline in a bridge lower belly in the field of water supply and drainage construction, which comprises the following steps of: 1, pre-burying a plurality of steel plates on a beam plate in the bridge lower belly, and welding a fixed bracket on the pre-buried steel plates; step 2, manufacturing a sliding bracket; 3, the pipeline is lifted and placed on the sliding support at one end, close to the shore, of the bridge through a forklift, and the pipeline is installed in place; 4, a first winch is placed at one end of the bridge, a nylon rope is tied to one end of a steel wire rope on the winch, and the steel wire rope is conveyed to the other end of the bridge after an installation person climbs up a fixing support; a second winch is arranged at the other end of the bridge; the pipeline can penetrate through the fixing support installed in the lower belly of the bridge, the pipeline is conveyed to one end of the bridge from the other end of the bridge to be installed in place, the pipeline and the pipeline which is installed in place are welded in a butt joint mode, the construction cost is greatly reduced, and the construction problem that other machines cannot conduct hoisting is solved.

Description

technical field [0001] The invention relates to a pipeline installation method in the field of water supply and drainage construction. Background technique [0002] When water pipes cross rivers, they are often installed on bridges. For this kind of construction, it is necessary to pre-select the location for installing the pipeline on the bridge. Generally, it is usually installed on both sides of the bridge. In this way, the crane can be directly used to drive the bridge deck to hoist the pipeline in place, which is easy to operate. However, sometimes due to special reasons, the surface of the bridge does not have a part reserved for pipeline installation, so it can only be installed in place from the underbelly of the bridge. However, after the bridge is built, auxiliary facilities such as floating bridges have been withdrawn. For installation, cranes and other equipment cannot be operated on the water surface, and the pipeline needs to be installed through the bottom of...

However, sometimes due to special reasons, the surface of the bridge does not have a part reserved for pipeline installation, so it can only be installed in place from the underbelly of the bridge. However, after the bridge is built, auxiliary facilities such as floating bridges have been withdrawn. For installation, cranes and other equipment cannot be operated on the water surface, and the pipeline needs to be installed through the bottom of the river, but the construction cost is extremely high
