The data put forward specific construction requirements and technical requirements for railway tunnel portal works, shotcrete, tunnel excavation, anchor rod construction, steel frame and reinforcement mesh construction, pipe shed and advance small conduit construction, lining construction, tunnel waterproof and drainage, surrounding rock monitoring measurement and other sub project operations, which can guide the construction of the same project. [Content excerpt] Construction procedures for tunnel excavation: advance geological prediction → surveying and setting out → drilling → charging and detonation → ventilation and smoke exhaust → danger removal → slag removal → entering the next process...... After the bending of the steel frame is completed, trial assembly shall be carried out on the processing site first. Each section of steel frame shall be assembled with accurate size and smooth arc. The error along the surrounding contour of the tunnel shall be no more than 3cm, and the middle error of the bolt hole of the connecting baseplate shall be no more than ± 5mm; When the profile steel frame is placed horizontally, the plane warpage is less than 2cm [attach chart], the portal construction process flow chart, the list of personnel and equipment, the allowable deviation and inspection method for the installation of the end wing wall formwork, the deviation and inspection method for the excavation size of the end wing wall foundation pit, the construction process flow chart for the excavation of the tunnel body, the main equipment configuration table for advance geological prediction, the geological advance prediction plan table Process flow diagram of advance geological prediction construction, schematic diagram of main control network of cross conductor, cut hole coefficient table, charging coefficient a value, full face excavation process, bench method construction process, ring excavation reserved core soil method excavation section and process, three bench temporary inverted arch method process and process, three bench seven step excavation method construction process flow diagram CRD method construction process flow, shotcrete construction process flow diagram, shotcrete anchor construction sequence diagram, allowable deviation of each plate of raw materials, anchor rod construction process flow diagram, steel frame and reinforcement mesh construction process flow diagram, allowable deviation of steel frame installation, construction process flow diagram of advanced long pipe shed, allowable deviation of pipe shed drilling, process flow diagram of advanced small tremie Invert and inverted arch filling construction process flow chart, lining construction process flow chart, formwork installation allowable deviation and inspection method, rebar processing allowable deviation and inspection method, minimum period of concrete curing, rebar installation and protective layer thickness allowable deviation (mm) and inspection method, tunnel waterproof and drainage construction process and flow chart, waterproof board laying construction process flow chart Schematic diagram of waterproof board hanging points, main physical properties of plastic waterproof board, flow diagram of surrounding rock monitoring and measurement, layout diagram of ground settlement measurement points, measurement frequency, deformation management grade table......
