Product Description:

Building Tunnel 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:

◆ High stiffness, make perfect shape for concrete.

◆ Easy operation, save labor and force.

◆ Fast forming, repeatedly turnover.

Q:Who can give me detailed tunnel construction process
Tunnel construction process, the first branch is a temporary payment, two lining is a permanent support.1, the hole before the edge, the construction of the slope (including drainage, electricity, etc.);2, the construction of large pipe shed3, measurement positioning line;4, drilling, blasting;5, slag, playing anchor, steel, injection (including the initial spray and spray)6, ahead of the anchor (after the pipe section)7, measuring the line;
Q:I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
You are talking about the design of the tunnel two lining car software.
Q:Tunnel construction technology and method
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:What is the role of the tunnel formwork trolley? What is the use of template trolley?
The use of full circle wear line; side and roof arch lining are most commonly used, two concrete lining construction commonly used in highway, railway tunnel and underground cavern.
Q:Main diseases and prevention of tunnel
Main diseases and prevention of tunnel1 over excavation in tunnel excavationPhenomenon: in tunnel excavation, the upper, lower, left and right contours are exceeded.The reason analysis: the measurement is not allowed, the deviation is big; the hole position deviation is bigger; the hole in the hole drilling process does not have the straight hole to have the slanting hole to exceed the limit; the blasting parameter choice is wrong, the charge quantity is too much or unreasonable.Preventive measures: to ensure the measurement work turnover review system; accurate calculation of blasting parameters, the formal process test before entering the tunnel, timely adjust the parameters change of geological condition; hole position and direction control in drilling process.
Q:The tunnel lining is wood, how should support?
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:Concrete construction technology of tunnel roof?
The floor concrete is made by the method of subsection pouring, the length of each section is about 16 ~ 24m, and the construction joint is kept between each construction section. After pouring concrete floor, due to the need for roughly 7 days to meet the design requirements of concrete strength, to remove the floor above the first steel purlin and support. During this period of time can be the first construction of steel bars and formwork works, and then the construction of the outer wall of the leveling layer and the wall of the waterproof layer.
Q:On the interpretation of the specialized words in tunnel
You haven't even touched the tunnel. Simply to say that the lining is the use of concrete or reinforced concrete tunnel inside the template pouring. The author is to stabilize the stability of the rock itself, followed by the tunnel in order to facilitate the application of.
Q:What grade of concrete used for tunnel cushion
Course (bed) refers to the structural layer below the base level. Its main function is to separate water, drainage, antifreeze in order to improve the working conditions of the base and foundation, and its water stability requirements.
Q:Would you please tell me the difference between the concrete and shotcrete in the tunnel?
Jet coagulation: the construction method of spraying fine concrete with spray gun. It is often used to fill the lining of tunnel lining, wall, ceiling and other structures.
