TUNNEL FORMWORK

The automatic hydraulic tunnel formwork is the equipment to make
the concrete lining for the tunnel in one time.The empty gantry allows the
transport vehicles to pass. The motor gearbox is adopted to drive
the whole equipment, the formwork is fully hydraulic, with hydraulic
cylinder to prop & strip, and lock mechanically

◆  Good concreting quality,fully hydraulic.With hydraulic
cylinder to prop & strip, and lock mechanically

◆  High-speed of installation and removal of the form

◆  Easy operation and safety.The empty gantry allows the
transport vehicles to pass.

Q:How to calculate the lining formwork trolley in tunnel construction
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.
Q:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?
If the reinforcement in advance or tied to the design of no reinforcement, the normal situation down the car, plus the plug plate, pouring concrete
Q:How to remove the template of the two lining trolley moving outside the tunnel
No, the car is a mechanical structure, the first car on the template brush oil release agent or diesel oil, to prevent sticking
Q:Demolition of tunnel bearing formwork for several days
The average temperature of 20 degrees, can be removed for 28 days. High temperature removal time is short, low temperature stripping time longer.
Q:When the tunnel fight, there is no provision for the number of meters hit
Electric heating plate can be used for bonding or cold bonding (rubber water seal) or welding (plastic water stop) method, such as user connections are difficult, I can send technical personnel on-site guidance.
Q:Tunnel steel arch behind the steel mesh after a layer of fine iron wire mesh what effect is there?
4, the production and installation of the grid steel frame components of the steel truss structure for the production of the tunnel excavation of the initial support of the steel frame. The steel grid with steel and steel by welding is composed of steel frame, steel grille by assembling (bolting, welding) after the formation of the steel arch structure after initial support structure of sprayed concrete, which is applied in soft soil tunnel structure is the most effective measure.
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:How to set the location of the tunnel trolley,
The next two large positioning along the side mode, re positioning of two small side mode along the point, then turn to check the center point and elevation, if not the positioning deviation is complete, then re adjust the positioning deviation! If you have time to measure the location of the site can be set up, then you do not nail this method, the five points directly to the elevation and mileage can be controlled for a long time
Q:Two tunnel lining reinforced concrete template to price behavior can be contracted
There is two times of lining concrete pouring, the normal price is within 100 yuan, this is the pure artificial price, does not contain steel trolley and various materials two tunnel lining.
Q:Tunnel construction procedure A cycle of steps
The construction and tunnel portalWith the support from top to bottom layered excavation hole slopes, and Myeong Dong, and permanent and temporary outside waterproof and drainage should be first, make the surface smooth water, avoid surface water erosion on slope. Is necessary to take artificial slope repair, prevent overbreak, reduce disturbance to the adjacent area; excavation slope will be used in the design of the door, reducing exposure to rock weathering, support to follow, within the jurisdiction for high slopes, if not timely, can not guarantee the safety, and many of the human condition waste,The lining must check and recheck side wall foundation Myeongdong geologic condition and the bearing capacity of the foundation, to meet the design requirements, measurement lofting, frame formwork support, assembling reinforcement, inside and outside the template, the first wall arch integral casting lining concrete, mixing pump into the mold, insert type vibrator with attached type vibrator tamping compaction device.For the construction of portal portal with cut bamboo, also for cutting bamboo cut, plane mounted wooden formwork according to the slope, the slope angle and side end die die fixed into a whole.The waterproof layer and backfillingAfter the completion of open cut tunnel lining strength up to 50% can be removed outside the mold, with a waterproof layer, each layer of backfill should be symmetrical on both sides of the height difference is not greater than 30cm, not more than 50cm, after re stratified backfill to the vault, filled to the completion of a good surface aquifuge.
