Detailed drawing of bridge pile foundation and cushion cap reinforcement of a project

Stage 1: Leveling the site, foundation pit excavation and slope protection. 2. Pile foundation construction, cushion cap construction, and tower base pouring. 3. Formwork erection and pouring of tower column starting section. 4. Install tower crane and construction elevator. 5. Pour the lower tower column in sections to the lower beam, and set the embedded reinforcement of the lower beam, formwork support and embedded parts of the truss piece. 6. Continue pouring tower columns in sections to a certain height, and set horizontal supports between tower columns. 7. Install the lower beam bracket and preload it. 　　

1、 The elevation shown in the figure is in meters, which is the 1985 national elevation datum. Other dimensions are in millimeters. 2、 Material: 1. Cement: ordinary Portland cement should be used, and efficient anti-seepage admixture should be used in construction. 2. Concrete: C25 for caisson wallboard, C15 3 for cushion concrete. Steel: symbol "^" means HPB235 rebar;

This drawing is the node diagram of simply supported beam abutment pile foundation reinforcement structure

2. Design standard According to the requirements of the assignment, the design load of this bridge is steam level 20 and hanging level 100. The bridge is 7.5m wide and the carriageway is 6.5m wide. Cement concrete deck is adopted. 3. Geology of the bridge site The landform of the bridge site belongs to the intermountain valley landform, and the terrain elevation varies from 37.00m to 45.00m. The two banks are the alluvial terraces of the Xinxing West River. Because of water storage and power generation, the water depth is always about 3.00m~4.00m. Stratum characteristics at the bridge site are Quaternary alluvium (clay, loam and round gravel) and Cambrian sedimentary rock (weakly weathered sandy shale, strongly weathered sandstone and weakly weathered sandstone) from top to bottom. The seismic fortification intensity of the site is 6 degrees, and the design basic seismic acceleration value is 0.05g.
