Bridge widening and splicing method

Abstract

The invention discloses a bridge widening and splicing method which comprises the following steps: 1, pre-embedding reinforcing steel bars and pouring required splicing pieces in advance in a factory, cooling and forming the splicing pieces, and storing the splicing pieces indoors; 2, transporting the poured splicing pieces by a plurality of transport vehicles, and transporting the needed splicing pieces to a construction site for standby application; 3, unloading the splicing pieces transported to the construction site one by one, quality inspection is conducted one by one after unloading is completed, whether the splicing pieces meet the construction standard or not is checked, meanwhile, whether the splicing pieces are damaged or not in the transportation process is checked, and registration is performing if the splicing pieces are damaged; and 4, starting to prepare equipment for new and old bridge construction. According to the method, the balance degree of widening of the new and old bridges is considered by means of laser, so that the problems that when the new and old bridges are widened, people need to observe the balance degree by means of eyes, deviation is caused, and the service life is shortened are effectively solved.

Description

technical field [0001] The invention relates to the technical field of bridge widening, in particular to a bridge widening splicing method. Background technique [0002] In recent years, with the rapid development of my country's economy, my country's transportation industry has made great progress. However, due to the increasingly frequent flow of people and materials, the demand for transportation has increased sharply. The existing scale and level of highways are increasingly difficult to meet the requirements of economic development. The "2012 Statistical Bulletin on the Development of Highway and Waterway Transportation Industry" compiled by the Planning Department of the Ministry of Communications in 2013 pointed out that the national highway daily average in 2012 The traffic volume is 21,305 vehicles, the average daily driving volume is 2,047.17 million vehicle kilometers, and the annual average traffic congestion degree is 0.35, an increase of 7.3%, 20.2% and 5.7% resp...

Problems solved by technology

[0005] Another object of the present invention is to provide a bridge widening splicing method, which realizes the consideration of the balance degree of widening the old and new bridges by relying on lasers, thereby effectively avoiding the need for personnel to rely on eyes to observe the balance degree when widening the old and new bridges, resulting in confusion Misalignment occurs, which reduces the service life of the problem
