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

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: Loess tunnel construction quality control points: The main points of concrete construction of tunnel invert:1) should advance concrete arch wall concrete construction of inverted arch arch and the construction should be removed before water, slag and other sundries, false

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: The tunnel lining is wood, how should support?: Small pipe or large, medium pipe shed is the advanced support for the broken rock area or into, out of the hole, of course, grouting, grouting without losing the significance of the implementation.

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.

Q: Design of lining concrete is C30, what should be used in the construction of concrete arch cushion concrete?: 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: 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.: 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: What are the reasons for the two lining concrete lining of the tunnel?: (3) the concrete pump tube, vibration rod and other mechanical repeated impact, workers trample or vibrator touch bar, caused by displacement and deformation of steel exposed.

Q: Tunnel construction procedure A cycle of steps: 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: 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).
