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:How to fill in the tunnel template
The template is firm and smooth, there is no error, such as leakage
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:Tunnel lighting design steps, 2 teachers said to design a template
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:What is the simple calculation method of the tunnel excavation unit price
Comprehensive unit price = labor cost + material equipment fee + mechanical + management fee + profit
Q:How to set the location of the tunnel trolley,
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),
Q:What are the driving jobs in the tunnel
Outside control traverse 2) elevation control survey 3) in construction traverse
Q:The small side wall of the small side wall and inverted arch in the high speed tunnel
The self - made invert sliding formwork trolley is used to fix the side plate directly on the trolley. This is the best way
Q:The bridge template that the highway needs, probably with what kind of thickness can satisfy
Hello, highways, bridges, tunnels, dams, railways and other projects, are generally used in bridge plate 12/15/18MM specifications
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:I would like to ask the tunnel step method excavation, the height of each step is how to divide?
On the circular arc heading cutting method, the excavation of each cyclicfootage and steel frame with same interval, after the excavation will be used in the initial support, the excavation behind the steps of 8~10m, after the excavation construction of initial support and invert, and then the middle rock pillar grouting reinforcement. (4) of excavation the surrounding rock and the surrounding rock in deep buried section IV and supporting: IV rock by step excavation method, step up the steps behind 8~10m, up and down the steps of primary support construction must follow with the excavation. Rock class take the whole section excavation method. (5) are the simple types of rock excavation self assembling drilling trolley, with dump truck shipment mucking loader. In order to ensure the safety and stability of tunnel construction in soft rock section, the construction must follow the "weak blasting, little disturbance, short excavation, strong support and frequent measurement, tight lining", in the application of The following measures shall be taken
