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
Advantage
◆ Good concreting quality
◆ High-speed of installation and removal of the form
◆ Easy operation and safety
- Q: 1 tunnel lighting design steps, 2 teacher said to design a template, is not to create a tunnel, and then according to the numerical calculation of what?
- The pupil is 5 times as fast as the increases, which makes the dark adaptation time to defend much longer. Cone cells can produce or reduce pigment in 10 ~ 12min, and the rod cells are almost 60min need to produce all of the pigment, which makes it very difficult for people to adapt to a very dark environment. How long does it take, depending on the extent of illumination.
- Q: The tunnel lining is wood, how should support?
- 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: What are the driving jobs in the tunnel
- Control wire measurement in the cave 5) elevation control survey 6) through survey (7)
- 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 know the safety awareness of the tunnel lining formwork trolley Prawns to help answer oh
- Two during the 1 excavation of earthwork calculating boundary line is important??? 2 measuring points as far as the standard
- Q: What is the width of a ring in a tunnel
- Of course, the assembly of the tunnel, such as subway shield tunnel, a ring is the length of the shield segment, there are 1.0m, 1.2m, 1.5m, 2.0m.
- 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.
- 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: 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: 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
