2. Design load: steam - level 20, hanging - 120; The crowd is 3.5KN/m2. 3. Bridge deck motorway: two-way four lane; Design clearance of motorway under the bridge: 4m. 4. The main structure of the bridge adopts prestressed concrete continuous monolithic slab, partially prestressed concrete Class A members, and longitudinal and transverse two-way prestressed system. 5. Cylindrical piers are used as piers, gravity abutment is used as abutment, and rigid expanded foundation is used as abutment foundation. 6. The bridge foundation shall be constructed by open excavation, and the superstructure shall be constructed by integral cast-in-situ support and one-time frame dropping. 　　

2. Design load: highway - Class I 3. The upper span of this bridge is composed of 3x50+(115+220+115)+5x50+25m, of which the 50m span is fabricated prestressed concrete continuous T-beam, the main bridge is prestressed concrete continuous rigid frame, and the 25m span is prestressed concrete cast-in-place box girder. The substructure is hollow thin-walled pier and pile column pier, the abutment is rib slab abutment and column abutment, and the whole bridge foundation is bored pile. 4. The seismic peak acceleration of the bridge site is 0.05g. 5. Pier beam consolidation is adopted for No. 2, 7, 8, 9 and 10 piers of this bridge. 　　

This document is the construction organization design for the replacement of the original pier by the new portal pier of a super large bridge. The new pier adopts the scheme of outsourcing prestressed concrete capping beam, with accurate design and clear nodes, which has certain reference value for bridge and culvert designers. 　　...... There are 5 CAD design drawings in total.

2、 Technical indicators: 1. Design load: highway Class I; 2. Environment category: Class I; 3. Structure importance coefficient: 1.1; 4. Span: 30m; 5. Skew angle: 0 °; The longitudinal bridge direction of the bridge is designed as flat slope, and the transverse bridge direction gradient is 2%. One link is a fabricated partially prestressed concrete T-shaped continuous beam of 3 × 30m to 6 × 30m. The structural system of multi T single prefabrication, simple support installation and cast-in-place continuous joint is adopted. The bearing setting mode shall be determined by calculation according to the temperature amplitude, the number of holes per link, the height of piers and other specific conditions, except that the sliding plate bearing shall be set at each link end bearing.

4.1.1 Double column piers are used for simply supported beams and rigid frame side piers, and tie beams are used to connect the top of pile foundation. 4.1.2 The main pier of rigid frame is double thin cantilever pier, the center spacing of thin cantilever pier is 570cm, the horizontal dimension is the same as the bottom width of box girder, which is 850cm, the vertical dimension is 130cm, the height of cushion cap is 350cm, the horizontal X vertical dimension is 1280X1120cm, and eight pile foundations are arranged in quincunx shape. 　　

2. Design load: highway - Class I 3. The upper span of this bridge is composed of 3x50+(115+220+115)+5x50+25m, of which the 50m span is fabricated prestressed concrete continuous T-beam, the main bridge is prestressed concrete continuous rigid frame, and the 25m span is prestressed concrete cast-in-place box girder. The substructure is hollow thin-walled pier and pile column pier, the abutment is rib slab abutment and column abutment, and the whole bridge foundation is bored pile. 4. The seismic peak acceleration of the bridge site is 0.05g. 5. Pier beam consolidation is adopted for No. 2, 7, 8, 9 and 10 piers of this bridge. 　　

This data is a general drawing of continuous structure of the bridge deck with a width of 13.5m. The design is accurate and the drawings are complete, which is worthy of reference. 　　..
