Construction method for narrow steel hanging box of straining beam in water

Abstract

The invention relates to the field of wading bridge construction, in particular to an underwater straining beam narrow steel hanging box construction method which comprises the steps that a narrow steel hanging box composed of a bottom plate, side plates and an I-shaped steel framework platform is built, the position of the steel hanging box is adjusted through finish rolling spiral steel bars, the steel hanging box can move up and down, and the elevation is easy to control; a rubber plate, concrete and a self-secreting expansion mortar water stopping bag are adopted for sealing water, a good water sealing effect can be achieved, and then steel bar binding and concrete pouring operation is conducted in the steel hanging box subsequently. According to the method, the construction cost is greatly saved, the construction process of the straining beam in water is greatly simplified, the influence on the width of the cross section of the river channel is reduced to the greatest extent, the problems of complex underwater construction process, difficult construction, large investment, high cost and the like are solved, and meanwhile, the working efficiency and the working quality are improved.

Description

technical field [0001] The invention relates to the construction field of wading bridges, in particular to a construction method of narrow-width steel suspension boxes for tie beams in water. Background technique [0002] With the rapid development of my country's social economy, the development of my country's transportation engineering industry has been rapidly improved. At the same time, the transportation industry is also an important basic construction of my country's economic construction. Transportation not only facilitates people's travel, but also speeds up industrial transportation. As an important project in the traffic engineering industry, bridge engineering is widely used in today's engineering construction. [0003] In the process of bridge engineering, wading bridges are usually encountered. For the construction of tie beams in water, the traditional construction method mostly adopts the steel cofferdam construction method. These construction methods all need...
