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:Who can give me detailed tunnel construction process
In addition, after blasting excavation contour line must be used with artificial picks excavation, fill hole hole blasting is prohibited, should use the diamond, completes the construction of temporary drainage hole, the pump discharge hole, quartz, mica schist will accelerate the loss of self stability in water immersion, and will accelerate the development of the formation of rock joints, if the groundwater pressure too much damage to increase support.
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:Demolition of tunnel bearing formwork for several days
The removal time of concrete wall and beam column pouring template is determined according to the strength of concrete, different situations: different removal time of concrete strength of the bottom die and the bracket removal should meet the following requirements:
Q:How to set the location of the tunnel trolley,
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:Where is the B-B section of the tunnel invert reinforcement
Tunnel invert refers to the bottom of the tunnel (anti arch, so called inverted arch)
Q:There are no recycling tunnel templates
Tunnel template, as far as I understand, is the tunnel two lining template
Q:On the measurement of total station
Steel arch support and Lifang line checking, bottom excavation and invert excavation, lining template checking and lofting, invert pavement template checking, reinforced lofting and lining ditch school inspection, line and template checking
Q:How to fill in the tunnel template
There seems to be a quality inspection form,Send a template to see
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.
