In 1957, the Wuhan Yangtze River Bridge was completed. Mao Zedong called it "a bridge flying from north to south, and "Natural transportation gap" becomes "unobstructed road"". It vividly describes the majestic momentum of the Wuhan Yangtze River Bridge and its important role in my country's north-south traffic. The "one bridge" in the word refers to the Wuhan Yangtze River Bridge, and "trench" means a ditch for traffic. "One bridge flies north and south, and the sky becomes a thoroughfare" means that after the Wuhan Yangtze River Bridge is completed, the Yangtze River will become a smooth road.

　　The "cable hanging basket" designed and manufactured by Hebei Dongfeng Shijing Railway Group Co., Ltd. is an artifact that realizes the bridge construction of the "Natural transportation gap" becomes "unobstructed road". "Cable hanging basket" is also one of the high-quality products that the company has independently developed and produced and obtained national patents.

　　Hanging basket is the main equipment in cantilever construction. According to the structure, it can be divided into truss type (including flat-chord unbalanced weight type, rhombus, triangle, bowstring type, etc.), diagonal type (including triangular diagonal type and prestressed diagonal type) Type), steel type and mixed type 4 types. According to the requirements of concrete cantilever construction technology and design drawings for the hanging basket, comprehensively compare the characteristics, weight, steel type and construction technology of various forms of the hanging basket to determine the structure of the hanging basket; the hanging basket construction does not occupy the road or river surface at all, and does not need to Interrupt the main and auxiliary road traffic and shipping, relying on the movement of the "hanging basket", so that the concrete box girder poured on site will be produced in the "hanging basket". The construction staff will cast 2-8 meters long each time, and the bridge body will harden and reach sufficient strength. , The hydraulic device will push the hanging basket forward, and then pour a new section of beam.

　　The design principles of the hanging basket: light weight, simple structure, strong and stable, easy to move forward, easy to assemble and disassemble, strong reusability, small deformation after stress, and sufficient space under the hanging basket, which can provide larger construction operations The surface is conducive to the construction operation of steel formwork.

　　Liuchuan Town, under the jurisdiction of Jianhe County, Guizhou Province, is located in the northwestern part of Jianhe County. It is mainly a gathering place for the Miao, Han, Dong, and Shui ethnic groups. The town’s forest coverage rate reaches 64%, with abundant forest resources. Qingshui River is the largest river in southeast Guizhou Province, belonging to the Dongting Lake water system in the Yangtze River Basin. The Qingshui River flows through Liuchuan Town, with high mountains and dense forests on both sides, speed boats on the river, fresh fish swimming in the water, beautiful and charming scenery.

　　Recently, the pouring operation of the 3# main tower 1# beam section of the Qingshui River Bridge 3# Main Tower 1# beam section of the Qingshui River Bridge in Guizhou Jianrong No. 4 Standard for the entire control project has been completed, marking that the bridge construction has officially entered the cantilever hanging basket construction stage.

　　The cantilever cast-in-place of the Qingshui River super large bridge section adopts a long platform compound suspending cradle, which is the first cable-stayed bridge constructed by this technology in China Communications First Public Bureau Group. In order to ensure the smooth progress of the cantilever construction of the hanging basket of the bridge, Hebei Dongfeng Shijing Railway Group Co., Ltd. designated technical personnel to actively communicate with the project department, optimize the construction plan, and complete the safety technical disclosure. From the installation and commissioning of the hanging basket formwork and stay cables On-site guidance to ensure the safety and quality of the suspension cable hanging basket during the construction phase.

　　The main bridge of the Qingshui River Bridge is a prestressed concrete cable-stayed bridge with two towers and a central double cable plane with a 300-meter span of "tower, beam and pier consolidation". It is divided into 97 beam sections, of which the 0# block and side span 24# beam section adopts the support cast-in-place construction method, the mid-span closing section adopts the hanger construction method, and the remaining beam sections adopt the front fulcrum hanging basket suspension cast construction method.

　　I wonder if you read the article of the editor, do you really understand that "Natural traffic gap" turned into "unobstructed road" is achieved through the help of the artifact "towing basket"?
