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.

Bridge Formwork System for Building construction

Q: I would like to ask the tunnel step method excavation, the height of each step is how to divide?: Tunnel excavation adopts mechanical construction, tunnel excavation using simple self assembling drilling trolley, millisecond detonator, in order to improve the effect of smooth blasting around the eyes, around the eye using special Nonel detonation. Tunnel outlet using muck loader, dump truck with transport ballast. Two tunnel lining concrete use of the length of integral pouring formwork trolley 12M, concrete mixing station in centralized mixing, concrete transport vehicle transport pump into the mold.

Q: 1 tunnel lighting design steps, 2 teacher said to design a template, is not to create a tunnel, and then according to the numerical calculation of what?: When the light into the human eye increases, the pupil contraction, when the surrounding environment becomes dark; into the human eye when the light is reduced, the pupil increases.

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: What are the driving jobs in the tunnel: Control wire measurement in the cave 5) elevation control survey 6) through survey (7)

Q: Who can give me detailed tunnel construction process: In addition, after blasting excavation contour line must be used with artificial picks excavation, fill hole hole blasting is prohibited, should use the diamond, completes the construction of temporary drainage hole, the pump discharge hole, quartz, mica schist will accelerate the loss of self stability in water immersion, and will accelerate the development of the formation of rock joints, if the groundwater pressure too much damage to increase support.

Q: Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?: 2, ingate construction shaft sealing, to get rid of advanced small pipe grouting reinforced concrete, and supported the upper ingate upper grille steel frame, injection, get rid of the upper concrete lower reinforced concrete, erecting of ingate to spray the concrete lower grille steel frame.

Q: I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh: Two during the 1 excavation of earthwork calculating boundary line is important??? 2 measuring points as far as the standard

Q: Tunnel two lining car moving outside the template after the demolition of how the car is similar to the nature of the sliding movement and concrete off: No, the car is a mechanical structure, the first car on the template brush oil release agent or diesel oil, to prevent sticking

Q: Two tunnel lining reinforced concrete template to price behavior can be contracted: This problem should belong to the industry confidential!If the two lining of the tunnel is pure manual, the normal price is between 800 and 650,

Q: How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?: 6 excavation methods of tunnel1, full section method2 step method3, three steps of the 7 step excavation method4, septal wall method (CD method)5, the intersection of the next door method (CRD method)6, double side drift method
