Q:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
5, the construction of the lining structure in the construction process of the power tunnel, the construction of the first lining structure is the eighteen word construction principle of the strong support principle. Construction of lining structure is the guarantee and foundation of tunnel construction safety.
Q:Who can give me detailed tunnel construction process
Tunnel construction process, the first branch is a temporary payment, two lining is a permanent support.1, the hole before the edge, the construction of the slope (including drainage, electricity, etc.);2, the construction of large pipe shed3, measurement positioning line;4, drilling, blasting;5, slag, playing anchor, steel, injection (including the initial spray and spray)6, ahead of the anchor (after the pipe section)7, measuring the line;
Q:I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
Tunnel lining trolley design software is CAD, the use of the software for the design of the structure
Q:What is the concrete construction of the tunnel invert
As the name implies, concrete is the concrete that needs to be supportedv
Q:How to remove the template of the two lining trolley moving outside the tunnel
In addition there is a template on the trolley Jack and hydraulic cylinder electric control, can be extended to shrink, when the formwork is to open the template of the trolley, when the contraction of template removal
Q:There are no recycling tunnel templates
Tunnel template, as far as I understand, is the tunnel two lining template
Q:Main diseases and prevention of tunnel
Insufficient anchor tensionPhenomenon: anchor installation is not strong, pulling force is not enough.The reason analysis: anchor length is not enough; mortar grouting is not full; mortar wrapped anchor thickness is not enough or not at all; holes in the debris is not clean; the depth of the hole with the length of the bolt is not matching.Preventive measures: the hole diameter should be matched with the bolt diameter; strictly according to design deep hole drilling; grouting pressure and wind pressure water rinse perforations; bolt rust, straightening, ensure the bolt and hole center line on the same line of installation; the hole from the bottom of the hole, uniform and continuous. Midway not interrupt; using earlystrong medicine package bolt, the bolt diameter should be treated with perforation diameter matching.
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:How to fill in the tunnel template
There seems to be a quality inspection form,Send a template to see
