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.

Q:On the measurement of total station
Slag road slope line, shotcrete receiver measurement, measurement of highway tunnel excavation section, the most important measure is the monitoring and measurement precision of total station but couldn't finish that much. Ha-ha
Q:How to remove the template of the two lining trolley moving outside the tunnel
In addition there is a template on the trolley Jack and hydraulic cylinder electric control, can be extended to shrink, when the formwork is to open the template of the trolley, when the contraction of template removal
Q:Demolition of tunnel bearing formwork for several days
The average temperature of 20 degrees, can be removed for 28 days. High temperature removal time is short, low temperature stripping time longer.
Q:How the tunnel template is calculated
The construction specification requires that the main hole should adopt the full section lining formwork trolley, and the other cars can be connected, the man and the equipment can be assembled.At present, the construction of the tunnel in our country basically uses the steel formwork trolley, many provinces and cities have set the minimum thickness of the template.
Q:What are the safety awareness of the tunnel lining formwork trolley?
Second, check the obstacles before starting, the process of attention to observe at any timeWire, wind
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:Concrete construction technology of tunnel roof?
Concrete construction technology of tunnel roof:Due to the main roof, the floor of a large amount of concrete pouring, consider the construction period and other factors, the site is equipped with 2 sets of automotive pump or HBT60 pump and 300m Phi pipe and a variety of accessories.
Q:How to design the general layout of the tunnel construction organization design
I need to contact you to provide a template..
Q:How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
And these kinds of excavation methods need to determine the number of excavated meters according to the grade of surrounding rock. Tunnel invert and floor is completed after the initial support (that is, shotcrete, a layer of concrete, in the excavation of rock on some hard rock without vertical spray arch thin, weak surrounding rock shall be sprayed on the vertical arch thickness in this special project map will show) for pouring 2 reinforced concrete lining when left in general is 6~12 meters
Q:What grade of concrete used for tunnel cushion
The thickness of the cushion should not be less than 70mm, and the concrete strength grade should not be less than C10;
