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: For example, lining, invert, bias and so on words,, to answer the full thank you
- Bias: refers to the formation of the tunnel, resulting in uneven pressure. To provide you with a few books you go to see the explanation. The site is easy to understand.
- 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: The arch and the arch of the tunnel
- Tunnel invert refers to the bottom of the tunnel (anti arch, so called inverted arch)
- 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: Main diseases and prevention of tunnel
- Tunnel shotcretePhenomenon: the concrete spray layer and the rock surface is not bonded, concrete spray layer between the bond is not good.Cause analysis: the loose rock not clear spray surface; shotcreted rock debris is not scum washing or flushing thoroughly with wind pressure, water pressure; surface by spraying water, water, water concentration of untreated concrete spraying interval; before a layer of spray surface without wind, water washing scum. The air pressure is inconsistent with the spray distance.Preventive measures: remove the loose rock, clear surface by spraying of water, slag floating debris; water, concentrated water point of the surface by spraying with gouge, guide the drainage treatment of buried pipe; sprayed concrete before spray test, to determine the wind and spray distance coordination relationship between.
- Q: What are the steps? If you build a template, how to fill in the concrete. The tunnel is to dig all the generalist pouring, or digging into the side. Simply say. Better picture. In addition, we have seen a video, the shield machine to dig up the tunnel after the installation of a number of prefabricated panels, but these prefabricated plate is curved. Do not have to fill in a semicircle tunnel?
- Two lining trolley consists of two parts, one is the erection and welding of steel trolley, and the other is pouring trolley.
- 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: 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: How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
- And these kinds of excavation methods need to determine the number of excavated meters according to the grade of surrounding rock. Tunnel invert and floor is completed after the initial support (that is, shotcrete, a layer of concrete, in the excavation of rock on some hard rock without vertical spray arch thin, weak surrounding rock shall be sprayed on the vertical arch thickness in this special project map will show) for pouring 2 reinforced concrete lining when left in general is 6~12 meters
