Building Tunnel Formwork：
A compositional steel formwork system mainly used in the building which has regular structure
without beams, the excellent formwork system can make the integral pouring for the wall & slab
easily achieved.
Characteristics:
◆ High stiffness, make perfect shape for concrete.
◆ Easy operation, save labor and force.
◆ Fast forming, repeatedly turnover.
- Q: Ask, general highway tunnel measurement with the total station to measure which aspects? The more detailed the better
- Slag road slope line, shotcrete receiver measurement, measurement of highway tunnel excavation section, the most important measure is the monitoring and measurement precision of total station but couldn't finish that much. Ha-ha
- 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: For example, lining, invert, bias and so on words,, to answer the full thank you
- You haven't even touched the tunnel. Simply to say that the lining is the use of concrete or reinforced concrete tunnel inside the template pouring. The author is to stabilize the stability of the rock itself, followed by the tunnel in order to facilitate the application of.
- 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 hole in the template above people standing on the head of I welded pipe, connected with concrete pump.
- Q: How the arch of the tunnel concrete pouring up, how to support before pouring, using I-beam is directly support the earth?
- Two concrete tunnel lining, template is used according to the size and shape of the tunnel design custom-made, I-beam welded frame, welded steel plate, known as the "two trolley liner" (hydraulic jack lifting and installation of steel wheel moving on the rail), is generally the length of 9~12m, concrete pouring pump concrete.
- 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: 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: A detailed method is introduced
- 5) the construction of open cut tunnel reinforced concrete structure construction is divided into two parts: first, the construction of inverted arch and wall foundation of reinforced concrete, to be part of the concrete reaches certain strength, stripping, cutting hair construction joints, and construction of the upper side wall and arch of reinforced concrete. The inverted arch and wall part of the composite steel formwork, artificial pouring, side wall and arch concrete construction formwork for the internal mold, and molded with combined steel formwork, formwork and external bracing to ensure stable, symmetrical pouring concrete, steel processing plant in processing molding, binding site. The concrete is produced by the automatic metering concrete mixing station, the concrete transport vehicle transportation, the concrete pump into the mold, the insertion type tamping device is compacted, and the arch wall concrete is completed once.6) water proof construction, laying waterproof layer, tunnel construction on the surface of concrete repair chisel flat uneven place to prevent damage of waterproof board. The weld quality of the waterproof board shall meet the requirements. If there is any defect, corrective action must be taken to meet the requirements.7) arch backfilling: Myeongdong vault above maximum backfill height 2m, compaction degree '93% fill in the top-level clay layer of water, the backfill surface of turf.Back fill both sides of the symmetry at the same time, the bottom of the wall filled with 0.5m ~ 1m thick gravel and compacted, and then the use of artificial layered backfill, layer by layer compaction. Careful protection of the waterproof layer during backfilling is not destroyed.The water layer of clay and the side, the slope of the lap is good, close to prevent surface water leakage.
- Q: What is the first project of tunnel constructionNow to do some of the tunnel program, you need to be the first to list out, a total of what? I know that the first branch, two lining, inverted arch, tunnel, pavement these
- Summary of construction of the first two tunnel lining
- Q: I would like to ask the high-speed rail tunnel invert small side wall and arch with the small side of the wall of the hanging formwork of what a good method?
- The pouring of inverted arch and the pouring of the short side wall, do not step in place, install the side die on the invert
