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.


◆ 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 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: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 bridge template that the highway needs, probably with what kind of thickness can satisfy
According to the actual situation of your project
Q:What is the vault vault seal and seal
Directly in the template hole, make a steel plate bolt
Q:What are the reasons for the two lining concrete lining of the tunnel?
(3) the concrete pump tube, vibration rod and other mechanical repeated impact, workers trample or vibrator touch bar, caused by displacement and deformation of steel exposed.
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: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:How to arch the arch concrete pouring
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:Would you please tell me the difference between the concrete and shotcrete in the tunnel?
These two kinds of concrete construction method is actually the difference.Formwork concrete: after the formwork is good, the concrete is the concrete, such as the tunnel lining, the bridge pier and so on.
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
