Steel Tunnel formwork system

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:: Concrete construction technology of tunnel roof:Due to the main roof, the floor of a large amount of concrete pouring, consider the construction period and other factors, the site is equipped with 2 sets of automotive pump or HBT60 pump and 300m Phi pipe and a variety of accessories.

Q: How the tunnel template is calculated: According to the experience and the reuse rate of the template, the thickness of the single lane tunnel template is 10mm, the thickness of the single three lane template is 12mm, and the thickness of the one-way tunnel is 15mm. Consider the length of the template and the construction of the impact of general 10m, not more than 12 meters.

Q: How to design the general layout of the tunnel construction organization design: I need to contact you to provide a template..

Q: The tunnel has the super big pipe shed and the lead small conduit, is carries on the blasting excavation first or carries on the advance support first, has the anchor rod in the tunnel, this between the construction craft order is any: The excavation of invert waterproof plate, blind pipe and steel bar at the bottom of the tunnel, and the pouring of invert arch

Q: I would like to know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh: Second, check the obstacles before starting, the process of attention to observe at any timeWire, wind

Q: What is the role of the tunnel formwork trolley? What is the use of template trolley?: The car is often used in the construction of hydraulic tunnel, the tunnel is not allowed to have concrete construction longitudinal joints, in the hydraulic tunnel span is large

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: How to calculate the lining formwork trolley in the tunnel construction, is the fixed assets or the turnover materials?: In the construction of the tunnel lining template can belong to the low value consumables in accounting, purchasing back into low value, and share in the future cost of 50%, scrap reamortization into 50% of the cost of this method is of low value consumables 55 amortization method; fixed assets, equipment car belonging to the class the asset depreciation period of 10 years. The lining template trolley for a device, rather than separate accounting, and the template should be turnover materials? Added: I engaged in casting model in the low value consumable, car is of course equipment assets added: template is a collar with the repeated use of the low value consumables, which belongs to the class of tools, you can also be classified as turnover materials, but according to the use of reasonable cost sharing principle after ask: you the manufacture of accounting, and it is in the tunnel construction, the construction enterprise to buy trolley. I personally feel that the template should be separated from the car accounting, so more true and accurate. Thank you

Q: Two tunnel lining reinforced concrete template to price behavior can be contracted: Specific price mainly depends on the length of the tunnel, which is the size of the project, and the geological conditions of tunnel is the tunnel construction is now the price of pure artificial price, the specific price or to the bidding price and the construction unit price guide, after all, the project is now basically is the lowest bid, the inevitable choice to compress all fees is the construction unit.If you need to complete the tunnel labor contract price and the cost of all, you can continue to ask questions, hope to adopt!

Q: There are no recycling tunnel templates: If you want another company for the recovery of tunnel two lining trolley, the specific type of price and the address of the template of the trolley that would be able to better the template of the trolley recovery, to play its due value template trolley.
