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.

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:How the tunnel template is calculated
According to the experience and the reuse rate of the template, the thickness of the single lane tunnel template is 10mm, the thickness of the single three lane template is 12mm, and the thickness of the one-way tunnel is 15mm. Consider the length of the template and the construction of the impact of general 10m, not more than 12 meters.
Q:Two tunnel lining reinforced concrete template to price behavior can be contracted
There is two times of lining concrete pouring, the normal price is within 100 yuan, this is the pure artificial price, does not contain steel trolley and various materials two tunnel lining.
Q:The small side wall of the small side wall and inverted arch in the high speed tunnel
The pouring of inverted arch and the pouring of the short side wall, do not step in place, install the side die on the invert
Q:What is the role of the grid steel frame and steel mesh in the power tunnel
The production of the grid steel frame component production and installation grid steel frame component is suitable for the production of the steel frame of the initial lining and the support of the digging tunnel. The steel grid with steel and steel by welding is composed of steel frame, steel grille by assembling (bolting, welding) after the formation of the steel arch structure after initial support structure of sprayed concrete, which is applied in soft soil tunnel structure is the most effective measure.
Q:On the interpretation of the specialized words in tunnel
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: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: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:How to fill in the tunnel template
The template is firm and smooth, there is no error, such as leakage
Q:When the two lining of the tunnel is used as the lining concrete of the two, how to lay out the trolley
The first measurement group with total station will be five points (template center, 2 large side mode along the point, 2 small side mode along the projection point) in lofting invert, with nails into the inverted arch concrete as a symbol, and note the nail surface elevation. The trolley positioning, the first to the two lining trolley running mileage, and positioning, positioning process will have been completed two off the top two tight lining lining, free end positioning first center point positioning control of elevation and with a plumb line (top surface elevation is equal to the length of the plumb line + if the mileage of two the center point of elevation can be lining)
