Product Description:

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:

◆ High stiffness, make perfect shape for concrete.

◆ Easy operation, save labor and force.

◆ Fast forming, repeatedly turnover.

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:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?
Seven hours after the maintenance of formwork, pouring a every day is no problem, that is to say a month to about fifteen die casting.
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 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 many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
6 excavation methods of tunnel1, full section method2 step method3, three steps of the 7 step excavation method4, septal wall method (CD method)5, the intersection of the next door method (CRD method)6, double side drift method
Q:What are the reasons for the two lining concrete lining of the tunnel?
(4) improper concrete mix, segregation, depending on the template part of the lack of slurry or template serious leakage;(5) no watering wood template wet, water bonding or early form removal, Chaimo missing edge off angle, resulting in reinforcement.
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 fill in the tunnel template
The template is firm and smooth, there is no error, such as leakage
Q:How to arch the arch concrete pouring
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:Two lining concrete pouring should adopt the combination of steel formwork system and formwork trolley two template system.
Two lining concrete pouring mould capable of self walking
