FAQ

What is the role of the tunnel formwork trolley? What is the use of template trolley?

The utility model is mainly composed of a simple lining trolley, a full hydraulic automatic walking lining trolley and a grid type lining trolley. Full hydraulic lining trolley can be divided into the side and roof arch, circular needle beam, bottom mold, full circle needle beam through type etc.. It is also widely used in the construction of hydraulic tunnel and bridge that the lifting sliding mode, the lifting sliding mode and the turning mode, etc..

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

Where is the B-B section of the tunnel invert reinforcement

Tunnel invert refers to the bottom of the tunnel (anti arch, so called inverted arch)

How to design the general layout of the tunnel construction organization design

The location and sketch map of explosive storehouse, spoil yard, office location, living area, entertainment area, temporary drainage ditch.

A detailed method is introduced

1 overall construction planUsing the new Austrian tunneling method, the construction principle is "less disturbance, early spray anchor, ground measurement, tight closure". The rock excavation method of construction; rock class micro bench excavation, pre splitting blasting; IV surrounding rock by construction method (Section IV surrounding rock under the partial, the construction step method), smooth blasting technique; fault fracture zone by middle wall construction method.The ballast is unloaded by the side unloading loader.Two lining the rail trolley, concrete mixing truck to transport concrete, pumping concrete, lining after decoration engineering construction.It is necessary to strengthen the geological prediction in the fault fracture zone and water rich zone, and provide the basis for the construction.

Would you please tell me the difference between the concrete and shotcrete in the tunnel?

Jet coagulation: the construction method of spraying fine concrete with spray gun. It is often used to fill the lining of tunnel lining, wall, ceiling and other structures.

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.

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.
