- Q: I would like to ask the tunnel step method excavation, the height of each step is how to divide?
- The side ditch construction using composite steel formwork. (1) the temporary facilities of tunnel construction plan layout: in the single ended due to tunnel entrance, temporary facilities of tunnel construction in tunnel exit to the right. The layout for the layout of wind mechanical equipment in the right side of the roadbed export based on the terrain conditions, reservoir located in the left side from the position of about 80m. In the mechanical approach immediately after the entrance of earth excavation construction, roof slope and drainage ditches slope anchor slope reinforcement, well hole digging for. (2): the excavation and reinforcement the mechanical construction, according to the construction method of Subgrade Earthwork excavation, dig to the rock when, in order to minimize the disturbance of the entrance slope and subgrade slope, must adopt the method of weak blasting and presplitting blasting for excavation. The entrance slope using hang net shotcrete reinforcement, to facilitate the safety hole (3). The excavation and support of the shallow section of the surrounding rock of the cave: the construction method adopts the step method, and the advanced grouting bolt is adopted on the stage
- 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:
- Before pumping concrete, the water in the storage hopper is pumped out of the pipeline to achieve the purpose of wetting and cleaning pipes. And then added to the cement mortar and concrete mix proportion in the hopper (or 1:2 cement mortar), lubricating pipe can start pumping concrete; start pumping, pumping speed slow, hydraulic pressure in the acceptable range, to be pumping well, only with the normal speed of pump. Concrete pumping concrete for continuous operation, if not timely, need to reduce the pump speed, the pump is temporarily interrupted, don't stop stirring; pumping finished cleaning pipes, using air compressor driven cleaning ball, and then immediately wash the concrete pump and pipeline, pipeline disassembled according to different specifications of classification.
- 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: What is the role of the grid steel frame and steel mesh in the power tunnel
- The back cover, shaft ingate construction, to get rid of the upper advanced small pipe grouting reinforced concrete, erecting of ingate upper grille steel frame, injection, get rid of the upper concrete lower reinforced concrete, erecting of ingate to spray the concrete lower grille steel frame.
- Q: The arch and the arch of the tunnel
- This part of the tunnel lining is generally the first pouring, pouring formwork trolley can be placed on the inverted arch concrete and support, to the construction of the tunnel arch wall concrete.
- Q: What is the width of a ring in a tunnel
- The car is generally long 9m can be a one-time pouring, a ring is a pouring two lining length
- Q: In the tunnel construction, the water stop belt and the water stop strip are respectively used in what place, the construction joint and the subsidence seam many meters set a, above all has any function
- Fixed strip: the use of additional reinforcement fixation; special fixture fixed; the wire and fixed template (Figure 2), such as perforation, can only choose the installation area on the strip edge, not to damage other parts
- Q: Two tunnel lining reinforced concrete template to price behavior can be contracted
- Specific price mainly depends on the length of the tunnel, which is the size of the project, and the geological conditions of tunnel is the tunnel construction is now the price of pure artificial price, the specific price or to the bidding price and the construction unit price guide, after all, the project is now basically is the lowest bid, the inevitable choice to compress all fees is the construction unit.If you need to complete the tunnel labor contract price and the cost of all, you can continue to ask questions, hope to adopt!
- 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
