Building Bridge Formwork:
A compositional steel formwork system mainly used in the building which has regular structure
without beams, the excellent formwork system can make the integral pouring for the wall & slab
easily achieved.
Characteristics:
◆ No assembling, easy operation with formed formwork.
◆ High stiffness, make perfect shape for concrete.
◆ Repeatedly turnover is available.
◆ Widely applied range, such as building, bridge, tunnel, etc.
- Q:Main diseases and prevention of tunnel
- Insufficient anchor tensionPhenomenon: anchor installation is not strong, pulling force is not enough.The reason analysis: anchor length is not enough; mortar grouting is not full; mortar wrapped anchor thickness is not enough or not at all; holes in the debris is not clean; the depth of the hole with the length of the bolt is not matching.Preventive measures: the hole diameter should be matched with the bolt diameter; strictly according to design deep hole drilling; grouting pressure and wind pressure water rinse perforations; bolt rust, straightening, ensure the bolt and hole center line on the same line of installation; the hole from the bottom of the hole, uniform and continuous. Midway not interrupt; using earlystrong medicine package bolt, the bolt diameter should be treated with perforation diameter matching.
- Q:There are no recycling tunnel templates
- If you want another company for the recovery of tunnel two lining trolley, the specific type of price and the address of the template of the trolley that would be able to better the template of the trolley recovery, to play its due value template trolley.
- Q:When the two lining of the tunnel is used as the lining concrete of the two, how to lay the trolley? Please kindly explain steps.
- If the template comparison rules, the design center line directly, that is, the center of the car can be, and then measured elevation and the design elevation of the introduction of the real distance from the real point of the vehicle
- Q:How the arch of the tunnel concrete pouring up, how to support before pouring, using I-beam is directly support the earth?
- The excavation of the tunnel face, slag, to the primary support system, first hit the bolt, then use steel or steel made of steel, installation support in tunnel contour, and then sprayed concrete (poor surrounding rock hanging steel mesh, then sprayed fiber concrete).
- Q:The tunnel structure of plastic mould
- The tunnel model is a kind of tool form template which is used for pouring concrete wall and floor at the same time.Total tunnel mode tunnel mode and half tunnel mode two, the basic unit of the tunnel mode is a complete tunnel template, half tunnel is composed of a plurality of unit angle die, and then use the 2.5 tunnel mode to fight and become a complete tunnel mode.
- Q:A detailed method is introduced
- 5) the construction of open cut tunnel reinforced concrete structure construction is divided into two parts: first, the construction of inverted arch and wall foundation of reinforced concrete, to be part of the concrete reaches certain strength, stripping, cutting hair construction joints, and construction of the upper side wall and arch of reinforced concrete. The inverted arch and wall part of the composite steel formwork, artificial pouring, side wall and arch concrete construction formwork for the internal mold, and molded with combined steel formwork, formwork and external bracing to ensure stable, symmetrical pouring concrete, steel processing plant in processing molding, binding site. The concrete is produced by the automatic metering concrete mixing station, the concrete transport vehicle transportation, the concrete pump into the mold, the insertion type tamping device is compacted, and the arch wall concrete is completed once.6) water proof construction, laying waterproof layer, tunnel construction on the surface of concrete repair chisel flat uneven place to prevent damage of waterproof board. The weld quality of the waterproof board shall meet the requirements. If there is any defect, corrective action must be taken to meet the requirements.7) arch backfilling: Myeongdong vault above maximum backfill height 2m, compaction degree '93% fill in the top-level clay layer of water, the backfill surface of turf.Back fill both sides of the symmetry at the same time, the bottom of the wall filled with 0.5m ~ 1m thick gravel and compacted, and then the use of artificial layered backfill, layer by layer compaction. Careful protection of the waterproof layer during backfilling is not destroyed.The water layer of clay and the side, the slope of the lap is good, close to prevent surface water leakage.
- Q:How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
- This time you need to see the construction unit of customized templates or make a template for a few meters, such as the 6 template pouring 6 meters, 12 meters is 12 meters, but not more than 12 meters or less than 6 meters, the pouring of inverted arch lining 2, or a concrete filling or the floor, according to your concrete filling or bottom layer below is conducted when a one-time pouring process is only a few meters a few meters. You can take a look at TZ204-2008 "railway tunnel construction technical guide" fifth "construction method" learning
- Q:Would you please tell me the difference between the concrete and shotcrete in the tunnel?
- Characteristics of shotcrete:(1) the sprayed concrete has the characteristics of rapid growth, strong bonding force, high density and good impermeability. It can better fill the gap between the rock blocks, increase the integrity of the surrounding rock, prevent the free surface weathering and loosening, and work together with the surrounding rock.(2) the construction of shotcrete will transfer, pouring and tamping a few processes into one, and do not need a template, so the construction of fast, simple.(3) sprayed concrete can play an important role as early as possible.(4) compared with the concrete, the physical and mechanical properties of sprayed concrete are improved.
- Q:I would like to ask the high-speed rail tunnel invert small side wall and arch with the small side of the wall of the hanging formwork of what a good method?
- The self - made invert sliding formwork trolley is used to fix the side plate directly on the trolley. This is the best way
- Q:How to fill in the tunnel template
- There seems to be a quality inspection form，Send a template to see
