Cad construction drawing for design of simply supported bridge with a span of 10m

Content introduction [Project overview] In order to meet the navigation requirements of the river section with a net width of 40.00m and a net height of 6.00m, it is not appropriate to build piers in the river, and try to reduce the design elevation of the bridge deck and the filling height of the bridge head connection, so as to meet the requirements of the longitudinal slope of the bridge head connection and reduce the amount of engineering fill. Therefore, the through tied arch scheme with a net span of 56m is adopted for the superstructure, The substructure is connected to the bored pile foundation by the cushion cap. [Technical standard] (1) Plane line type: the whole bridge is in a straight section. (2) Load standard: Class II highway. (3) Channel class: the peer class of this reach is Class VI channel, two-way navigation. (4) Navigation clearance: according to the relevant provisions of the Inland River Navigation Standard (GB50139-2004), the navigation clearance width is 40.00m, 3. The navigation clearance height is 6.00m, the top angle is 3.50m wide, and the top angle is 2.00m high. (5) The highest navigable water level is 9.70m. (6) The design elevation of midspan is 16.525m, and the design elevation of beam bottom is 15.825m. [Structural key points] 1. Span combination: the main span is a through steel pipe concrete tied arch. The calculated span is 56m; One span prestressed concrete hollow slab beam is set on both sides, and the span combination is 20+56+20. 2. Main bridge: through steel pipe concrete tied arch. This bridge type is an external statically determinate structure, which has no horizontal thrust on the foundation, is suitable for soft soil foundation, and has a large span, small bridge building height, and greatly reduces the embankment filling height. 1) Arch rib: consists of two pieces, each of which is a φ 1000 × 12mm steel pipe (A3), and C40 micro expansion concrete is pumped in the pipe. Three zigzag wind braces are set between the two arch ribs, and φ 600 × 12mm steel pipes (A3) are used for the wind braces. 2) Tie beams: 2 in total, prestressed concrete rectangular section beams, with beam height of 1.00m and beam width of 1.20m; The beam height at 5m near the fulcrum gradually increases to 2.00m. The corbel is set at the pier top, on which the plate beam is placed. Eight bundles of 9 φ 15.24 high-strength steel strands are arranged in the tie beam. 3) Suspender: each arch rib has 9 suspenders. Except that the distance between the end suspender and the center of the tie beam support is 6.0m, the distance between other suspenders is 5.5m. The suspender is composed of 36 φ 7 high-strength steel wires, OVM-DM type heading anchorage is used, stainless steel pipe is covered, and micro expansion cement mortar is pressed to prevent steel wire corrosion. The upper end of the suspender is anchored in the arch rib, the lower end is anchored in the tie beam and tensioned at the bottom of the tie beam. 4) Cross beam and bridge deck: the two forms an integration, the cross beam is T-shaped, bottom width is 0.7m, height is 0.7m, and 4 bundles of 7 φ S15.2 steel strands are configured; The bridge deck is cast in situ with a thickness of 0.2m, and is configured with longitudinal prestressed tendons with a spacing of about 1.5m. 5) Bridge deck pavement: cast-in-place C40 waterproof concrete, with a thickness of 12cm. 3. Approach bridge: one 20m span prestressed concrete hollow slab girder bridge is set at both ends of the main bridge, and the slab girder height is 0.90m. The hollow slab is prefabricated and installed. 4. Substructure: bored piles are used for all foundations, the bearing layer of pile tip is pebble soil layer, and double row piles are used for main piers and abutments, with pile diameter of φ 1.0m. Single row piles with diameter of φ 1.2m are used for approach piers. The pier shafts are reinforced concrete column piers; Rib slab embedded abutment is used for abutment. An approach slab is set behind the abutment to connect with the approach road, and the length of the approach slab is 6.0m. The embankment behind the abutment shall be backfilled with power plant waste fly ash or fly ash spacer soil. The filling thickness of each layer shall be 0.3m, and the compaction degree shall adopt the heavy compaction standard. The compaction degree below 0.80m from the structural layer shall be 0.90. The compactness within 0.80m from the structural layer is 0.93.
