Q:What is the vault vault seal and dead seal please give a detailed drawing of the drawing bar do not know how to do?: The arch support is an adjustable template or a small template

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:I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh: No special requirements, not special equipmentFirst of all, it must be the track, the sleeper to the sleeper rail

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 first measurement group with total station will be five points (template center, 2 large side mode along the point, 2 small side mode along the projection point) in lofting invert, with nails into the inverted arch concrete as a symbol, and note the nail surface elevation. The trolley positioning, the first to the two lining trolley running mileage, and positioning, positioning process will have been completed two off the top two tight lining lining, free end positioning first center point positioning control of elevation and with a plumb line (top surface elevation is equal to the length of the plumb line + if the mileage of two the center point of elevation can be lining)

Q:There are no recycling tunnel templates: If it is a tunnel two lining car template, and the use of the tunnel after the car can continue to use the value of such a tunnel lining car basically has a market of two, but also to be recycled. The specific recovery and continue to use, mainly to see the two lining of the tunnel and the old and new without modification.

Q:Highway bridge template needs, probably with the thickness of both the construction requirements can be met, and more cost-effective?: It is best to use the high turnover times, can also be used as the use of the beam die, more cost-effective

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:How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?: This time you need to see the construction unit of customized templates or make a template for a few meters, such as the 6 template pouring 6 meters, 12 meters is 12 meters, but not more than 12 meters or less than 6 meters, the pouring of inverted arch lining 2, or a concrete filling or the floor, according to your concrete filling or bottom layer below is conducted when a one-time pouring process is only a few meters a few meters. You can take a look at TZ204-2008 "railway tunnel construction technical guide" fifth "construction method" learning

Q:How to put the positioning point is based on what is mainly based on my novice, do not: The trolley positioning, the first to the two lining trolley running mileage, and positioning, positioning process will have been completed two off the top two tight lining lining, free end positioning first center point positioning control of elevation and with a plumb line (top surface elevation is equal to the length of the plumb line + if the mileage of two the center point of elevation can be lining),

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.
