Crossing a water conveyance channel at stake 1+000, the bridge is temporarily called No. 3 Bridge. According to the principle of simplicity, economy and generosity, the bridge type of 30m simply supported beam plus arch abutment on both sides is selected. 1、 Design basis and specifications 1. Code for Design of Urban Bridges (CJJ11-93) 2. Standard for Design Load of Urban Bridges (CJJ77-98) 3. General Code for Design of Highway Bridges and Culverts (JTG D60-2004) 4. Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts (JTG D62-2004) 5. Code for Design of Subgrade and Foundation of Highway Bridges and Culverts (JTJ024-85) 6. Technical Standard for Highway Engineering (JTG B01-2003) 7. Technical Code for Construction of Highway Bridges and Culverts (JTJ041-2000) II. Technical Standard 1. Bridge design load standard: urban level B, population 4.0KPa. 2. River conditions: the planned river width is 40 meters, the river bottom elevation is -1.250 meters, the normal water level is 1.350 meters, and the flood level once in a century is 4.020 meters; It is controlled according to the navigation standard of Class 7 channel, and the normal navigation water level is 2.350m. 3、 Bridge crossing pipeline 1, power, communication and other pipelines with smaller diameters pass under the sidewalk slab. The water pipe and low-pressure gas pipe pass through the reserved pipe position. 4、 The planned width of the river channel where the No. 1 and No. 3 bridges are located is 40m, The bridge is 90 ° orthogonal to the river channel, the central stake is 1+000, and the form of cross section is: 3.5m (sidewalk)+3.5m (non motorway)+5m (green belt)+8m (motorway)+8m (motorway)+5m (green belt)+3.5m (non motorway)+3.5m (pedestrian road)=40m 2. The cross slope of motorway and non motorway is 1.5% outward, and the sidewalk is 1.5% inward. 3. The upper part of the bridge is a simply supported beam with a span of 30 meters, and arched abutments are arranged on both sides. The 30m hollow slab beam is 110cm high, the arch ring is 30cm thick, the arch axis is R275 arc, and the side wall is 50cm thick. The abutment arch is filled with 5% cement stabilized macadam. Arch ring, side wall, abutment, abutment cap and cushion cap shall be cast-in-situ. Support beam and cushion cap shall be cast at the same time. C-40 expansion joints are set on both sides of the abutment. The lower part of the bridge adopts bored pile foundation with a pile diameter of 100cm. V. Construction methods and precautions 1. Concrete construction requirements (1). The concrete color should be consistent with the whole bridge. The exposed parts should use the same type of cement from the same manufacturer and the same release agent. (2) The mix proportion of concrete shall be determined by test to ensure the strength of concrete. (3) Strictly control the geometric dimensions of each part, and control the construction error within the allowable deviation range of the construction specification. 2. Precautions for upper and lower construction (1). Construction procedures: excavation, hollow slab prefabrication - abutment - embedding and adjusting bearings - beam erection - backfill - bridge deck system - handrail. (2) During the prefabrication of the hollow slab of the superstructure, attention should be paid to embedding various embedded components, mainly including the railing embedded reinforcement. (3) Before erecting the beam, ensure that the contact surface of the support is horizontal. (4) After the bridge deck is erected, the overlapping reinforcement shall be welded firmly. Before the hinge joint concrete is poured, the floating skin on the joint surface must be removed, and the concrete and cement mortar in the hinge joint can only be poured after being washed with water. The hinge joint concrete and mortar must be vibrated and compacted. The beam bottom shall be hooked with flat joint. (5) In order to closely combine the bridge deck pavement with the precast hollow slab as a whole, the top surface of the precast hollow slab roof must be roughened and washed with water before pouring the bridge deck concrete. (6) The construction of bored piles shall be carried out in strict accordance with relevant construction procedures. Drilling, hole cleaning, reinforcement cage lowering and underwater concrete pouring shall be strictly organized during construction. (7) Requirements for filling behind abutment: graded gravel shall be used for filling in layers, each layer shall be 30cm thick, and the compactness shall be greater than 95%. Backfill behind abutment shall be filled to half the height of abutment before girder erection, and other filling shall be completed after girder erection.
