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: 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 periphery of the tunnel outline has been sealed with steel seal, and can be used as the external formwork when the concrete is poured. The 3 parts of the tunnel are divided into floor, side wall and roof. When pouring, the concrete can only be pumped in the tunnel, the outside of the tunnel is the Pearl River, and the construction can not be carried out outside the tunnel. The roof pouring, only from the bottom to the pump. Question: 1, the roof concrete pouring, how to discharge the air? How to tamper? 2, the tunnel width of 23 meters, you need to do the construction of the seam or after pouring it? Time is pressing, please reply as soon as possible. Good addition score. Thank you。 If you can't see the picture, click this link:
- Before pumping concrete, the water in the storage hopper is pumped out of the pipeline to achieve the purpose of wetting and cleaning pipes. And then added to the cement mortar and concrete mix proportion in the hopper (or 1:2 cement mortar), lubricating pipe can start pumping concrete; start pumping, pumping speed slow, hydraulic pressure in the acceptable range, to be pumping well, only with the normal speed of pump. Concrete pumping concrete for continuous operation, if not timely, need to reduce the pump speed, the pump is temporarily interrupted, don't stop stirring; pumping finished cleaning pipes, using air compressor driven cleaning ball, and then immediately wash the concrete pump and pipeline, pipeline disassembled according to different specifications of classification.
- Q: Loess tunnel construction quality control points
- 3) arch filled with rubble concrete should meet the requirements of the relevant regulations.4) concrete or rubble concrete arch above the back should reach the design strength of concrete arch in the back 70% after construction.
- Q: Would you please tell me the difference between the concrete and shotcrete in the tunnel?
- These two kinds of concrete construction method is actually the difference.Formwork concrete: after the formwork is good, the concrete is the concrete, such as the tunnel lining, the bridge pier and so on.
- Q: What are the driving jobs in the tunnel
- Control wire measurement in the cave 5) elevation control survey 6) through survey (7)
- 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: What is the width of a ring in a tunnel
- The car is generally long 9m can be a one-time pouring, a ring is a pouring two lining length
- Q: What are the steps? If you build a template, how to fill in the concrete. The tunnel is to dig all the generalist pouring, or digging into the side. Simply say. Better picture. In addition, we have seen a video, the shield machine to dig up the tunnel after the installation of a number of prefabricated panels, but these prefabricated plate is curved. Do not have to fill in a semicircle tunnel?
- Tunnel concrete is completed by the way of edge excavation and lining. After the excavation, the shotcrete is used as the initial support, and then the reinforcing steel mesh is set up. Only after the two lining.
- Q: I would like to ask the high-speed rail tunnel invert small side wall and arch with the small side of the wall of the hanging formwork of what a good method?
- Die casting. Install the inverted L hanger on the side wall.
- 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
