The bracket is proposed to be erected by bowl buckle scaffold, and the whole bridge is designed to be constructed by pouring and tensioning in sections. The structural form is as follows: the vertical pole spacing is 90cm under the box girder longitudinally, the thickening section under the end diaphragm and the top and bottom plate is 60cm, and the horizontal spacing is 60cm within 510cm under the box girder. According to the actual situation of the site, one column of ordinary steel pipes shall be densified for the longitudinal spacing at this place to strengthen the bearing capacity of the support at the web, which is 90cm below the wing plate; In the height direction, the step distance of the cross bar is 120cm, so that all the vertical bars are connected as a whole. To ensure the overall stability of the support, cross bridging is set in the horizontal and vertical vertical bars. The support preloading shall be carried out section by section according to the pouring section, and the subsequent construction shall follow closely, and the concrete shall be poured section by section.. ...... 25 pages in total, prepared in 2011

The main bridge of this bridge is 40+65+40 variable cross-section box girder structure. The box girder is a single box single room structure with straight web. The width of the box girder roof is 10.99m, the box width is 6m, the outer cantilever is 2.5m, and the road centerline side cantilever is 2.49m. The middle beam at both ends and midspan is 2.2m high, and the beam at the root of the pier top is 3.8m high. The height of the main beam is changed by a secondary parabola. The diversion channel is used to change the channel, and the construction platform is built. The full support method is used for cast-in-place construction of the whole couplet, which is cast in two times The thickness of the bottom plate at the middle section of the side span and middle span of the box girder is 25cm. The thickness of the bottom plate at the section towards the middle pier changes in a straight line. The thickness equation of the bottom plate is t=25+35 * (X/2700), where X is the distance from the calculated section to the starting point of the beam height change section. The thickness of the bottom plate at the cross beam at the top of the middle pier is locally thickened to 90cm within 2m from the cross beam, which varies in a straight line. The thickness of the bottom plate at the beam at the top of the side pier is thickened to 50cm within 7m from the beam, which varies in a straight line. The thickness of the web at the middle section of the side span and middle span of the box girder is 45cm. The thickness of the web at the section towards the middle pier changes linearly. The thickness equation of the web is t=25+30 * (X/2700), where X is the distance from the calculated section to the starting point of the beam height change section. The thickness of the web at the cross beam at the top of the middle pier is locally thickened to 120cm within 2m from the cross beam, which varies in a straight line. The thickness of the web at the top beam of the side pier is thickened to 75cm within 7m from the beam, which varies in a straight line. The structural drawing of main bridge box girder is attached below. The center line of the designed road of this bridge is located on a circular curve with a radius of 1980. The box top and bottom plates are both provided with a 2% cross slope. The top plate of the box girder is parallel to the bottom plate. The box girder is made of C50 concrete. The box girder is designed as a full prestressed concrete member longitudinally, and the transverse and cross beams of the bridge deck are designed as reinforced concrete members.

The starting point of Wenzhou Longgang Bridge Reconstruction Project is located near Wenzhou Gift City, Longjin Avenue, Longgang Town, Cangnan County. The starting point stake is K-1+760. The main line intersects Yanjiang West Road (Yanhu Road). Longgang Bridge spans (4 × 30m ＋ 4 × 30m ＋ 103.56m ＋ 2 × 30m ＋ 4 × 16m ＋ 4 × 16m ＋ 4 × 16m) across the Aojiang River, crossing the planned Binjiang Avenue, passing through Daitou New Village, and ending at the intersection of the Pingyang side connection of the original Longgang Bridge in Aojiang Town, Pingyang County, and the 104 National Highway. The ending stake number is K0+878.466, and the total length of the main line is 1118.466m. The cast-in-place continuous superstructure is a 16m span reinforced concrete constant section cast-in-place continuous box girder. The 4-span continuous box girder is a unit, with 3 units in total, and each unit is separated from the left and right. The beam is a single box three compartment section, with the beam height of 1.2m, the top plate width of the left box beam of 15.75m, the bottom plate width of 11.75m, and the cantilever length of 2m. The right box girder is widened inwards, with the top plate being 17.25m wide, the bottom plate being 13.25m wide, and the cantilever arm being 2m long. The thickness of box girder top and bottom plate is 25cm, and the thickness of web plate is 50cm. The cross beam of the box girder is prestressed, and the height of the cross beam is 1.5m (that is, the local heightening of the box girder at the fulcrum cross beam is 1.5m). The lower part of continuous box girder adopts pile column pier without capping beam. Each pier is transversely composed of two piles with a diameter of 1.3m and 1.5m.
