Product Description:

Single-side Bracket

During single-sided concreting, the concrete pressure is transferred into the sub-structure by

means of the single-side bracket.


Characteristics:

◆ For concrete heights up to 8.0m and a fresh concrete pressure up to a maximum of 60KN/m2.

◆ Good standard performance and versatility.

◆ Fast element coupling, all units can be quickly connected.

◆ The finished wall is excellent and absolutely waterproof.

◆ Optimized sizes for transportation.


Design Principle:

There is no wall-through tie-rod in the single-side bracket system. The whole system is adjusted by

the anchor system and the regulator system.

The stress situation from the sketch above.F1 can resist the side pressure of the concrete and F2

can resist the rising force. R can not only bear the gravity force of the bracket, but also the side

pressure of the concrete. This stress system is simple, reasonable and also with convenience and

high safety.

Q:What are the safety awareness of the tunnel lining formwork trolley?
No special requirements, not special equipmentFirst of all, it must be the track, the sleeper to the sleeper rail
Q:Tunnel lighting design steps, 2 teachers said to design a template
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:There are no recycling tunnel templates
If you want another company for the recovery of tunnel two lining trolley, the specific type of price and the address of the template of the trolley that would be able to better the template of the trolley recovery, to play its due value template trolley.
Q:How to arch the arch concrete pouring
Small pipe or large, medium pipe shed is the advanced support for the broken rock area or into, out of the hole, of course, grouting, grouting without losing the significance of the implementation.
Q:What are the driving jobs in the tunnel
Outside control traverse 2) elevation control survey 3) in construction traverse
Q:Loess tunnel construction quality control points
3) arch filled with rubble concrete should meet the requirements of the relevant regulations.4) concrete or rubble concrete arch above the back should reach the design strength of concrete arch in the back 70% after construction.
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: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 is the first project of tunnel construction
YK24 + 300 ~ YK24 + + 288 as the first project of the tunnel engineering. There are many factors that affect the quality of the two lining construction, each link in the construction process must be strictly in accordance with the construction specifications
Q:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?
According to the normal situation, three days a lining cycle, a month to play at least 9 plates!
