The Key Construction Calculation Of Long Wang Bridge

In this paper, based the project of Long Wang Bridge, namely in terms of pier construction,0#construction, construction and closure basket construction design and layout, etc. construction program, the technical quality of the construction requirements to make clear requirements for critical engineering design and carry out a special checking has important reference value for the actual construction. The main conclusions are as follows:First, a special program designed for the construction of a large volume of construction concrete bearing units located in water4#,5#piers were put forward in the fight to build the island cofferdam directly inserted locking steel pipe pile cofferdam cap forming method and the actual hydrological conditions were calculated, presented the performance indicators used in construction materials;Second, construction0#block is controlling the entire bridge construction project, the relationship between the quality and post-operation of the whole project. For Wang Long Bridge project, this paper presents the entire work program and construction0#0#Scaffording and design and calculation, and calculation of the mechanical properties of the stent0#calculate the force of the bottom die, vertical distribution of the beam the force, lateral force distribution of the beam, the beam Bailey force, the force distribution of the beam and pile pipe piles force, from all aspects of the bracket and the bracket template force calculation performed to ensure that the construction safe and reliable;Tird, using Cradle Construction of the bridge, the main beam construction is basically done on hanging basket, hanging basket or bad quality and stability is directly related to the construction of the security and control of linear. In this paper, the main girder bridge construction Cradle Lonwon were designed and targeted to meet the specific requirements of Stages make the bridge. Cradle of articles designed the overall composition, Cradle installation, Cradle Cradle of preload in advance. In this paper, hanging basket designed for the corresponding calculations carried out in order Cradle bottom mold systems and computing boom, the bottom mold stringers checking, before the end of the mold, the lower beam of the mechanical properties, the force on the beam performance analog front end, the mechanical properties of the strap, and the Cradle of the main truss and Cradle migration stress analysis carried out under its own weight and impact loads, making it one by one by checking to ensure the safe use of Cradle to ensure the able to guarantee the successful completion of the project quality and quantity;Forth, cross Close section of this article on the bridge and in the cross-section has been closed construction design, and closure plan for the corresponding checking. Cross Close calculated by the cross-section and the closure section, the control force conditions closed to ensure the smooth closure of the bridge, but also to ensure the safety and quality of closed construction.In this paper, based on the project, Wang Lung Bridge, studied the entire process of bridge construction, the construction process and the key construction projects for the corresponding program design, and the design of the program was the corresponding checking to ensure that every step of the job science and integrity, for the smooth construction of the bridge to provide a scientific basis, to ensure the safety and quality of construction of the bridge, to provide reference for similar projects.
