Embodiment Construction

[0030] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0031] The present invention provides a method for dismantling or erecting a bridge 1 over water, which is mainly carried out through the following steps: in dismantling or erecting the bridge 1 as a whole, according to the water level 5, rising / falling tide, etc. of the water area where the bridge 1 is located, the When the tide is low, the buoyancy generated by releasing the ballast water in the barge 2 is lifted to complete the dismantling of the bridge 1 at high tide; The bridge 1 is loaded into the pre-installation position, and the erection of the bridge 1 is completed. details as follows:

[0032] (-) Bridge dismantling

[0033] 1. Measure the water level 5, tide and environment in the water area where the elevation of the bridge 1 is located, and determine the required water le...

Abstract

The invention discloses a method for disassembling and assembling a superaqueous bridge, which combines the buoyancy change of a barge with the waterlevel change caused by the rising and the falling of the tide level. The method can be used in a light-draft area where a floating crane can not enter, and can be effectively and safely used within the carrying capacity range of a buoyant box.

Description

technical field [0001] The invention relates to a method for erecting a bridge, in particular to a method for dismantling or erecting a bridge over water. Background technique [0002] In the existing dismantling or erection of bridges over water, it is often affected by factors such as water level, environment, and operations in shallow draft areas where floating cranes cannot enter, and it is impossible to implement the overall dismantling or erection of bridges over water in shallow waters. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defect that the floating crane cannot be used for overall hoisting due to the influence of water level and environment in the dismantling or erection of the existing bridge, and to provide a bridge that can be installed in the shallow draft area where the floating crane cannot enter. It is a method of dismantling or erecting bridges that can efficiently and safely perform...
