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.


◆ 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:In the tunnel construction, the water stop strip and the water stop strip are used in what place
5, the user should be based on the order of the project structure, design drawings to calculate the length of the product, the special-shaped structure should have drawings, as far as possible in the factory will be connected to the whole
Q:How to remove the template of the two lining trolley moving outside the tunnel
The template is removed, the car generally has a fixed track, easy to move. What do not understand, you can secretly I hope to help you!
Q:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?
According to the normal situation, three days a lining cycle, a month to play at least 9 plates!
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:Tunnel construction procedure A cycle of steps
Excavation and support of shallow buried and broken section of V grade surrounding rock of portalHole wayThe thin covering layer, poor geological conditions, when the depth of excavation to the arch line, first into the hole wall and the guide pipe shed, the open cut tunnel lining after the completion of the long pipe shed is overlapped on the Dong, to form a fixed end of pipe roof support, opening into the inner wall in the protection of pipe roof under the heading of the two side wall to stagger the footage before and after (5 ~ 10m). If there is a small spacing must also be set prestressed anchor.
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:The tunnel lining is wood, how should support?
The excavation of the tunnel face, slag, to the primary support system, first hit the bolt, then use steel or steel made of steel, installation support in tunnel contour, and then sprayed concrete (poor surrounding rock hanging steel mesh, then sprayed fiber concrete).
Q:Tunnel construction sequence What is the sequence of construction process
Closed arch fill concrete pouring pouring arch fill fill arch wall waterproof plate arch wall steel reinforced concrete side wall chisel template trolley in the end of the work of the arch wall two lining concrete
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:How to arch the arch concrete pouring
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.
