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:I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
You are talking about the design of the tunnel two lining car software.
Q:1 tunnel lighting design steps, 2 teacher said to design a template, is not to create a tunnel, and then according to the numerical calculation of what?
The pupil is 5 times as fast as the increases, which makes the dark adaptation time to defend much longer. Cone cells can produce or reduce pigment in 10 ~ 12min, and the rod cells are almost 60min need to produce all of the pigment, which makes it very difficult for people to adapt to a very dark environment. How long does it take, depending on the extent of illumination.
Q:The arch and the arch of the tunnel
Tunnel arch wall refers to both sides of the tunnel wall and the top of the arch, the tunnel arch wall is generally the use of a template trolley.
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:When the two lining of the tunnel is used as the lining concrete of the two, how to lay the trolley? Please kindly explain steps.
The next two large positioning along the side mode, re positioning of two small side mode along the point, then turn to check the center point and elevation, if not the positioning deviation is complete, then re adjust the positioning deviation! If you have time to measure the location of the site can be set up, then you do not nail this method, the five points directly to the elevation and mileage can be controlled for a long time
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:What are the driving jobs in the tunnel
Control wire measurement in the cave 5) elevation control survey 6) through survey (7)
Q:There are no recycling tunnel templates
Tunnel template, as far as I understand, is the tunnel two lining template
Q:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
3, advance small catheter grouting small catheter with diameter of phi 32-50mm steel pipe, the tip of the tube and tube holes for special processing. The first row with drill drilling pipe. Row spacing is 30cm, fan shape, elevation of 5 degrees to about 8 degrees. The length is 2.25m, a single fluid grouting (cement) or double grout (cement water glass slurry). Adjust the grouting pressure according to the soil.
Q:How the arch of the tunnel concrete pouring up, how to support before pouring, using I-beam is directly support the earth?
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.
