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:

◆ 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:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
5, the construction of the lining structure in the construction process of the power tunnel, the construction of the first lining structure is the eighteen word construction principle of the strong support principle. Construction of lining structure is the guarantee and foundation of tunnel construction safety.
Q:In the tunnel construction, the water stop strip and the water stop strip are used in what place
5, the user should be based on the order of the project structure, design drawings to calculate the length of the product, the special-shaped structure should have drawings, as far as possible in the factory will be connected to the whole
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: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:Tunnel construction technology and method
The construction methods and technical measures2.1 construction processTo measure the slope, slope protection, Boulder rolling, processing or drainage construction, earthwork excavation, slope protection, inverted arch and side wall foundation construction, liming cave mould, steel banding, liming mould, pouring concrete, concrete outside the health to release, waterproof layer construction, backfilling and protection engineering construction.2.2 construction methods1) Myongdong and a complete portal excavation, excavation with full width transverse dredging method once formed, the first slopes, put the line before the excavation, then drain.2) with earthwork excavating, the small rock blasting method, drill hole, millisecond electric detonator, mucking loaders, dump truck transport, blasting near the slopes, with smooth blasting, in order to ensure the stability of slope. Excavation from top to bottom, side of the construction side slope excavation and slope into the face of the protection works.3) the first tunnel excavation after 10 ~ 20m, and then open cut tunnel lining. When construction, pay attention to Myeongdong and at the joint of the dark hole, from the inside out.4, before entering the cave, complete all slope reinforcement and protection measures.
Q:When the two lining of the tunnel is used as the lining concrete of the two, how to lay out the trolley
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:There are no recycling tunnel templates
Tunnel template, as far as I understand, is the tunnel two lining template
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:Tunnel construction sequence What is the sequence of construction process
Measuring and setting out the drill hole charge blasting, ventilation, smoke exhaust, water spraying and dust removing, the top of the vertical arch, the anchor rod and the reinforcing steel net, the spraying concrete operation enters the next cycle, and the first branch is stabilized and then the two lining is applied
Q:Would you please tell me the difference between the concrete and shotcrete in the tunnel?
These two kinds of concrete construction method is actually the difference.Formwork concrete: after the formwork is good, the concrete is the concrete, such as the tunnel lining, the bridge pier and so on.
