Various Processes of The Most Complete Curve Construction in History

Various Processes of The Most Complete Curve Construction in History

01 /Road engineering
1. Fill in road embankment: Construction preparation → Filling before base treatment → base detection → filling layer Filling → Fluttering of the bulldozer → flat aircraft and flat → test → record inspection visa → renovation formed molding
2. Excavation roads: Construction preparation → venue cleaning → excavation interceptor → excavation (slope repair) → transportation soil, stone square → digging side ditch → road slot renovation, crushing, molding → inspection and acceptance
3. Inorganic binding materials at the grassroots level: construction preparation → mixing material mixing → transportation → paving → compact → health → detection
4. Asphalt surface layer: construction preparation → Judu Stone installation → spraying through layer of oil → Test section Construction → mixed material mixing → transportation → compact → detection → testing
5. Cement surface layer: Construction preparation → template installation (sliding mold) → mixing material mixing → transportation → shop → vibration → seam treatment → anti -slip structure → health care
02/bridge engineering
1. The foundation of expansion and expansion: Construction preparation → excavation interceptor → precipitation facilities → encirclement structure (placed slope) → excavate layer by layer (human -machine cooperation; alternate with support) → base treatment → reinforced band bundle → template production → Watering → Conservation Demolition Model → Back Filling Flatter
2. Digging piles: Jingkou Protection Circle → (Artificial excavation → making wall protection) (cycle; air) → clearing the bottom → hanging steel cage → irrigation concrete
3. Drilling pile: Construction preparation → Buried protective tube → drilling rig position → Preparation of mud → drilling → clearing hole → reinforced cage production and hanging → irrigation underwater concrete
Plate steel bars processing and installation, prestressed pipe installation → internal mold installation → top plate steel processing installation and installation, end mold and anchor panel installation → prestressed tendon making → pouring box beam concrete → concrete maintenance → prestressed tendon tension → channel pressure Purgatory, sealing anchor → removing side molds, bottom molds and brackets → demolition, falling frame
5. Hanging basket method: The top 0 block of pier pier on the bracket or rack → The hanging basket is installed on the block No. 0 in order to be symmetrically poured into the Heilong section → the pouring side of the stent span the main Lianghelong section → the mid -crossing dragon section continuous (Heilong Dragon section continuous (Heilonglong (Heilonglong (Heilonglong Sequence: first, cross, then cross, and then cross)
6. Box Han top: On -site survey → engineering precipitation → work pit excavation → back production → skateboard production → laying lubricating isolation layer → box culvert production → top equipment installation → existing reinforcement → box culvert test top → eat soil → eat soil → eat soil → eat soil Top in → Monitoring volume test → box body position → removing reinforcement facilities → removing the back and the top equipment → workplace recovery
03/Rail
1. Underground continuous wall: excavation groove → build guide walls → excavation grooves → clearing slug bottom silt and residue → hanging joint pipe (rigidity, flexible) → hanging steel cage (hidden acceptance of supervision engineers) → lower catheter → irrigate concrete → pull out the joint tube
2. Light burial and dark excavation tunnel: advanced support → excavation → initial support → waterproof layer laying → secondary lining
3. Pipe shed construction: Put holes → Drilling machine position → Horizontal drilling → Pressing into the steel pipe → grouting (to the steel pipe or around the tube) → sealed → excavation → excavation
04/Water Supply and Sewerage
1. Overall watering pool: Measurement positioning → Turkish excavation and foundation treatment → cushion construction → waterproof layer construction → bottom plate pouring → pool wall and top plate support pillar watering → top board pouring → functional trials
2. Unit combined pool: Earthwriting excavation and foundation treatment → central pillar pouring → construction of pool bottom anti -seepage layer construction → concrete cushion layer of pouring pond → waterproof layer in the pond Silence → Pond Wall Waterproof Layer Construction → Functional Test
3. Test of the pond full water: test preparation → water injection in the pool → water level observation in the pool → evaporation measurement → finishing test conclusion
05/Domestic waste treatment engineering
1. Mud waterproof layer: Basis of acceptance site → Select the source of the anti -seepage layer → do multiple groups of different quantitative tests → Make multiple sets of soil -like water seepage tests → select the anti -penetration standard and economical ratio as the construction ratio as the construction ratio as the construction ratio as the construction ratio → Mix the soil samples according to the corresponding ratio of the construction site → Earth samples on the spot, compacted → layered construction synchronization test (compactness, water seepage test)
2. GCL pad: Base test → Hanging Putting on Putting → Artificial Putting Exhibition → Adjusting Width → Splending Palatum Powder at the overlap → Make follow -up construction
3.HDPE membrane: Hanging for position → laying → test adjustment → test welding (welding machine test welding, welded parts inspection) → welding (double seam heating, single seam extrusion) → weld detection (air pressure, vacuum, electricity, electricity, electricity, electric Spark; destructive) → Construction of the next step
4. HDPE osmotic collection of flower pipes: State debugging of the welded machine → Pipe preparation position → Pipelines to positive inspection → preheating (210 ± 10 ° C) → heating and melting → pressurization → reducing cooling (20-30min) (20-30min)
