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:Tunnel two lining car moving outside the template after the demolition of how the car is similar to the nature of the sliding movement and concrete off
- In addition there is a template on the trolley Jack and hydraulic cylinder electric control, can be extended to shrink, when the formwork is to open the template of the trolley, when the contraction of template removal
- 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
- The first project of concrete lining of this section as I bid the tunnel project, on the next two plays a role model leading lining construction, so the various factors must be considered in detail, before the construction plan, reasonable arrangement, strict control of construction process, construction timely summary, finally reached the first the United States, the project entity information is true and complete, the project finished good target
- Q:Loess tunnel construction quality control points
- 2) the invert, invert the filling layer and dry concrete construction should be concrete accurately, use the template, mechanical tamping compaction. The inverted arch concrete by pumping casting, should use the arch template ensure molding size meets design requirements. The construction of invert arch and filling layer should be completed according to the design of inverted arch concrete construction, the appropriate interval, and then change the proportion of concrete, filling layer of concrete construction;The construction of inverted arch and the cracks and deformation joints should be waterproof treatment according to design requirements, should be in accordance with the relevant provisions of this guide.Invert the overbreak in the allowable range, should be used with the same strength grade of concrete lining casting; overbreak exceeds, should according to the requirements of design and specification of the backfill, shall not use the random hole slag backfill, non intrusive rubble arch section.
- Q:The tunnel lining is wood, how should support?
- 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:Tunnel construction procedure A cycle of steps
- Excavation and support of shallow buried and broken section of V grade surrounding rock of portalHole wayThe thin covering layer, poor geological conditions, when the depth of excavation to the arch line, first into the hole wall and the guide pipe shed, the open cut tunnel lining after the completion of the long pipe shed is overlapped on the Dong, to form a fixed end of pipe roof support, opening into the inner wall in the protection of pipe roof under the heading of the two side wall to stagger the footage before and after (5 ~ 10m). If there is a small spacing must also be set prestressed anchor.
- 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:In the process of tunnel construction, two kinds of formwork system should be adopted in the construction of the two lining concrete. Q: what is the template trolley?
- Generally, a plurality of arc and straight steel die!Normal lining trolley
- 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: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 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
