Product Description:

Building Tunnel Formwork:

A compositional steel formwork system mainly used in the building which has regular structure

without beams, the excellent formwork system can make the integral pouring for the wall & slab

easily achieved.


Characteristics:

◆ No assembling, easy operation with formed formwork.

◆ High stiffness, make perfect shape for concrete.

◆ Repeatedly turnover is available.

◆ Widely applied range, such as building, bridge, tunnel, etc.

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:What is the vault vault seal and seal
The arch support is an adjustable template or a small template
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:What is the role of the grid steel frame and steel mesh in the power tunnel
The production of the grid steel frame component production and installation grid steel frame component is suitable for the production of the steel frame of the initial lining and the support of the digging tunnel. The steel grid with steel and steel by welding is composed of steel frame, steel grille by assembling (bolting, welding) after the formation of the steel arch structure after initial support structure of sprayed concrete, which is applied in soft soil tunnel structure is the most effective measure.
Q:Tunnel lighting design steps, 2 teachers said to design a template
When the light into the human eye increases, the pupil contraction, when the surrounding environment becomes dark; into the human eye when the light is reduced, the pupil increases.
Q:Two tunnel lining reinforced concrete template to price behavior can be contracted
This problem should belong to the industry confidential!If the two lining of the tunnel is pure manual, the normal price is between 800 and 650,
Q:How to set the location of the tunnel trolley,
The next two large positioning along the side mode, re positioning of two small side mode along the point, then turn to check the center point and elevation, if not the positioning deviation is complete, then re adjust the positioning deviation! If you have time to measure the location of the site can be set up, then you do not nail this method, the five points directly to the elevation and mileage can be controlled for a long time
Q:How many meters can be poured in the first floor of the 2 level of the surrounding rock of the railway tunnel?
6 excavation methods of tunnel1, full section method2 step method3, three steps of the 7 step excavation method4, septal wall method (CD method)5, the intersection of the next door method (CRD method)6, double side drift method
Q:I would like to ask the tunnel hydraulic trolley steel template design is the use of what software
You are talking about the design of the tunnel two lining car software.
Q:The arch and the arch of the tunnel
Tunnel arch wall refers to both sides of the tunnel wall and the top of the arch, the tunnel arch wall is generally the use of a template trolley.
