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.

Building bridge tunnel formwork

Q: The tunnel structure of plastic mould: In the use of the whole tunnel mode is not as flexible as semi tunnel mode, the lifting equipment requirements are higher, it is gradually being semi tunnelMode substitution.

Q: Highway bridge template needs, probably with the thickness of both the construction requirements can be met, and more cost-effective?: Hello, highways, bridges, tunnels, dams, railways and other projects, are generally used in bridge plate 12/15/18MM specifications

Q: For example, lining, invert, bias and so on words,, to answer the full thank you: Inverted arch: the general shape of the tunnel are horseshoe. Then the bow that you look up at is called an arch or vault

Q: How to put the positioning point is based on what is mainly based on my novice, do not: The next two large positioning along the side mode, re positioning of two small side mode along the point, then turn to check the center point and elevation, if not the positioning deviation is complete, then re adjust the positioning deviation! If you have time to measure the location of the site can be set up, then you do not nail this method, the five points directly to the elevation and mileage can be controlled for a long time

Q: How the arch of the tunnel concrete pouring up, how to support before pouring, using I-beam is directly support the earth?: Two concrete tunnel lining, template is used according to the size and shape of the tunnel design custom-made, I-beam welded frame, welded steel plate, known as the "two trolley liner" (hydraulic jack lifting and installation of steel wheel moving on the rail), is generally the length of 9~12m, concrete pouring pump concrete.

Q: What are the driving jobs in the tunnel: Outside control traverse 2) elevation control survey 3) in construction traverse

Q: What is the concrete construction of the tunnel invert: The construction of concrete is related to the non - construction concrete

Q: In the process of tunnel construction, two kinds of formwork system should be adopted in the construction of the two lining concrete. Q: what is the template trolley?: Generally, a plurality of arc and straight steel die!Normal lining trolley

Q: When the tunnel fight, there is no provision to fight how many meters left, only by one of the construction: Fixed strip: the use of additional reinforcement fixation; special fixture fixed; the wire and the fixed template (Figure 2).

Q: There are no recycling tunnel templates: If it is a tunnel two lining car template, and the use of the tunnel after the car can continue to use the value of such a tunnel lining car basically has a market of two, but also to be recycled. The specific recovery and continue to use, mainly to see the two lining of the tunnel and the old and new without modification.
