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
◆ High-speed of installation and removal of the form
◆ Easy operation and safety
- Q: Where is the B-B section of the tunnel invert reinforcement
- 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 the arch of the tunnel concrete pouring up, how to support before pouring, using I-beam is directly support the earth?
- The excavation of the tunnel face, slag, to the primary support system, first hit the bolt, then use steel or steel made of steel, installation support in tunnel contour, and then sprayed concrete (poor surrounding rock hanging steel mesh, then sprayed fiber concrete).
- Q: I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
- You are talking about the design of the tunnel two lining car software.
- 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: 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
- Closed arch fill concrete pouring pouring arch fill fill arch wall waterproof plate arch wall steel reinforced concrete side wall chisel template trolley in the end of the work of the arch wall two lining concrete
- 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: 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
- The construction methods and technical measures2.1 construction processTo measure the slope, slope protection, Boulder rolling, processing or drainage construction, earthwork excavation, slope protection, inverted arch and side wall foundation construction, liming cave mould, steel banding, liming mould, pouring concrete, concrete outside the health to release, waterproof layer construction, backfilling and protection engineering construction.2.2 construction methods1) Myongdong and a complete portal excavation, excavation with full width transverse dredging method once formed, the first slopes, put the line before the excavation, then drain.2) with earthwork excavating, the small rock blasting method, drill hole, millisecond electric detonator, mucking loaders, dump truck transport, blasting near the slopes, with smooth blasting, in order to ensure the stability of slope. Excavation from top to bottom, side of the construction side slope excavation and slope into the face of the protection works.3) the first tunnel excavation after 10 ~ 20m, and then open cut tunnel lining. When construction, pay attention to Myeongdong and at the joint of the dark hole, from the inside out.4, before entering the cave, complete all slope reinforcement and protection measures.
- 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: 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
