Product Description:

STAYED-CABLE CANTILEVER TRAVELLER

Stayed-cable cantilever traveller is applicable to large-scale stay-cable
cantilever casting bridge with wide bridge deck, heavy and long segment. Most of
the componants concentrates on bottom frame and walking system. It has no main
frame, at the same time, the lift is done by the stay-cable of the bridge. Comparing
with other types, the sigle weight of stayed-cable cantilever traveller is heavier.

●Low gravity of front trancerse beam

●Applicable to large-scale stay-cable cantilever casting bridge with wide bridge deck

●Safe & easy operation, easy fixing, and safty during walking

●Big operational space under the main frame, and easy installation and removal

Q:When the hanging basket method is used for the construction of continuous beams, the adjacent fast
1, have been pouring section (such as 0# block) of the end of the concrete to do all the processing of cutting hair.2, the first of two adjacent segments (such as 0# and 1#, 0# and 1 '#) all the longitudinal bars between the (steel web comprises a bottom plate, the roof and corresponding welding together).
Q:80m hanging basket construction section of how to pull the longitudinal tensile reinforcement
Internal tooth block! You look at the construction plans will know.
Q:Hanging basket construction steel binding labor costs a ton of money
Specific include: including equipment installation, removal, transportation, raw material transportation, loading and unloading vehicles, on-site storage custody
Q:How to deal with the broken of the cross beam of the hanging basket
Measurement of cracks can be watered with black ink, and then cut a section of cracks observed.The subsequent construction, the need to strengthen quality control, especially the control of masonry cracks in protective layer, the protective layer is too large or because most of the causes of cast-in-situ box cantilever especially should improve the understanding of crack, prestressed anchor head near the pipeline, after the proposal directly after chiseling epoxy resin mending.
Q:When hanging blue construction, middle span closure, why must the counterweight
First of all, the basket itself has weight. The weight of the hanging basket has some influence on the stress of the bridge, especially the construction state
Q:This paper puts forward the quality control points and methods of hanging basket continuous casting box girder
The key points of quality control: 1, hanging basket template (including the bottom mold and the side mold) elevation 2, hanging basket preloading ensuring the load quantity; 3, the hanging basket forward, need special attention, when the cradle walking the preparatory work before the improvement, check again walking and walking condition of anchor beam connection rod the bottom, hanging point should adopt steel wedge pad, and ensure the stability of suspension;
Q:Construction process of hanging basket
The tension must be carried out after 90% of the design strength, and in accordance with the order of the transverse beam of the top plate of the web. At the end of the tension, the grouting is carried out immediately, and after the grouting is finished, the hanging basket can be moved forward, and the construction of the next section of the box girder can be carried out.
Q:Seven techniques of hanging basket
Concrete pouring management should pay attention to seven technical measures10, 1 square hole. When pouring the concrete at the bottom of the roof, the roof plate can be opened on the two 50x 50 cm square hole, the concrete poured into the hole, to be completed after the completion of the concrete pouring floor sealing hole;10.2. is not overweight. When hanging basket construction concrete pouring V type pier, the difference between the pouring weight of the cross box girder and the cross shore box girder can not exceed 15 tons;10.3. symmetry. When pouring concrete in the same box girder section, it is necessary to carry out the operation of the left and right symmetry, so as to avoid the lateral displacement of the guide beam and cause the displacement of the front plane of the beam;
Q:Hanging basket dry steel, steel hinge line, how much money a ton
580 or so, including: equipment installation, removal, transportation, raw materials distribution, loading and unloading vehicles, on-site storage and storage;
Q:Hanging basket construction contract unit price
