The South Interchange Project of Dongshuimen Bridge is located in Shangxin Street, Nan'an District, mainly connecting the traffic between the South Approach Road of Dongshuimen Bridge and the Inner Ring Expressway. There are 7 ramps A, B, C, D, E, F and G, with a total length of 3.6km (including 2595.5m long bridge and 1004.5m long subgrade). At the same time, the reconstruction of the original Tushan Road, the Shangxinjie Station and the section tunnel of the rail transit loop line will be constructed.

2.1 The xx interchange is located on the xx to xx (xx boundary) highway in the xx boundary of the xx to xx link line (G7011) of the national highway, which belongs to the terrain of the mountain area. The upper layer of the interchange area is gravel soil, pebble soil, etc. with a thickness of 2 to 12.6 meters. The structure is moderately dense, and there is a relatively thin layer of artificial fill on the local surface. Below it is strongly weathered phyllite, with the allowable bearing capacity of strongly differentiated phyllite of 1200~1400Kpa and moderately differentiated phyllite of 2000~2400Kpa. The stratum within the depth of 28.5m below the ground mainly includes: ① gravelly soil, ② pebble soil, ③ strongly weathered phyllite, ④ apoplastic phyllite. The groundwater on the site is mainly phreatic water. The site underground diving and site soil are not corrosive to concrete and reinforcement. 2.2 xx interchange is divided into 12 bridges according to design unit.

The box girder section is a single box with two chambers, the beam height is 1.4m, and the deck width is 10.5m. The second hole (22 #~23 # piers) of the continuous beam of this couplet spans the hillside with a gradient of 1:1 and a height difference of 8m. The 23 # pier is located on the hillside, 5m away from the slope toe. The mark of cast-in-place box girder concrete is C40. 8cm C40 cast-in-place concrete and 10cm asphalt concrete are used for bridge deck pavement. ）In order to reduce damage to existing hillsides and ensure safety during construction, the following support scheme is proposed for construction in the overall construction scheme: erecting buttress with bowl shaped scaffold at the slope toe; Build ground beams on the hillside; I56a I-beam is used as the main beam to erect the door opening at the buttress and beam, and the calculated span is 8m. （2） Specific construction process 1. Construction process 1. Leveling the site, hardening the foundation, erecting piers and building ground beams, erecting longitudinal distribution beams, erecting transverse support beams, installing longitudinal main beams, installing transverse main beams, erecting scaffolding 2. Construction process (1) erecting piers, erecting piers with bowl shaped scaffolding, The erection parameters are: the vertical and horizontal directions of the upright within the base plate range are 0.3m; The horizontal spacing of vertical poles within the flange plate is 0.6m, and the longitudinal spacing is 0.3m; The step distance of cross bar is 0.6; The cross bridging shall be set up every other row horizontally and not less than 5 times longitudinally. Since the buttress is not perpendicular to the line direction, at least 5 rows of short side scaffolds shall be erected. The scaffold is erected on a 30cm thick C15 concrete base. The concrete base is 12m long, 1.5m wide and 30cm thick. After the installation of buttress jacking, a 2m long 10 × 15cm square timber shall be longitudinally placed on the jacking as a distribution beam.

Construction of cast-in-place box girder of an overpass in Pingdingshan City programme
A road and overpass project in Pingdingshan City, starting from Wuyi Road in the south and ending at North Ring Road in the north, is the main connecting channel between the central urban area and Pingdingshan mining area. Its line intersects with the branch road at the upstream of Chengdong River and Chengping Road, and crosses three special railway lines of Pingmei Group. The total length of the project is 1449 meters. The main bridge of an overpass is a 7-connected 33 span straight web continuous box girder with equal height, starting at K0+370.98 and ending at K1+42.764, with a total length of 671.78m; The wing bridge is a continuous box girder with two 10 span straight webs of equal height, starting at K0+550 and ending at K0+762.764, with a total length of 212.76m. The substructure of the main bridge and wing way bridge is the curved slab pier. The top surface size of the main bridge 1 #~8 # piers is 2.25m × 1.2m, and the bottom surface size is 1.5m × 1.2m. The top surface size of other piers and wing way piers is 3.1m × 1.2m, and the bottom surface size is 2.35m × 1.2m. The superstructure of the main bridge is ordinary reinforced concrete box girder with equal height straight web. The beam height is 1.3m and 1.5m respectively, the top plate thickness is 22cm, the bottom plate thickness is 20cm, the middle beam width is 1.5m, the end beam width is 1.0m, and the web width is 0.45-0.7m, 0.5-0.8m and 0.5m.
