Product Description:

UNCONVENTIONAL RHOMBIC FORM TRAVELLER

The front tranverse beam gravity height of unconventional rhombic
form traveller is betwwen the height of rhombic form traveler and
triangular form traveler. Comparing with rhombic form traveler and
triangular form traveler, it has the advantages of low gravity height,
more operational space than triangular form traveler, easy operation,
safety during walking and firm anchorage, etc..

● 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:What is the use of hanging basket
Are you talking about the construction of the bridge? Generally refers to the construction of continuous beams do not support the use of a special construction process
Q:Construction technology of bridge hanging basket
Beam section constructionA, adjust the elevation of the bottom mold, set the pre camber;B, lashing steel and web reinforcement, installation of floor and web longitudinal prestressed pipe;C, installation of internal mold;D, lashing roof reinforcement, the installation of vertical prestressed pipe;E, pouring concrete;F, health, tension, grouting, sealing anchor.
Q:Production and installation of hanging basket
In the construction, the construction quality of the corrugated pipe is good or bad, how to ensure the construction quality of the bellows? The main management measures are as follows:8.1. inventory. Bellows transported to the construction site, to enter the warehouse room stacked with the lower part of the board pad high, not rain, prevent rust o8.2. examination. Before the installation of corrugated pipe, to check the appearance to prevent deformation, there are trachoma bellows installed inside the o8.3. seal. The joint of the two bellows joints, to ensure that the length of the joint is not less than 30 cm, the distance between the two ends of the same, sealed with sealing tape joints to prevent leakage of slurry o
Q:Construction of extra large bridge
The installation span closure section hanging formwork installation, closure segment skeleton, formwork, steel banding, installation of prestressed pipe and the core concrete - span closure section, concrete curing - tension closure segment longitudinal, transverse and vertical prestressed grouting, demolition - span closure segment construction support.
Q:Seven techniques of hanging basket
10.5. tube. When the concrete is vibrated, we should pay attention to avoid the bellows to prevent the vibration rod from leaking;10.6. to nap. Because of concrete pouring, the surface still paving asphalt concrete, in order to enhance the bonding between the deck and asphalt layer layer of political government must firmly on the concrete surface roughening treatment:10.7. maintenance. After the concrete pouring, maintenance to improve the strength of concrete and prevent the formation of fine cracks, has an important role. Therefore, water conservation should not be less than seven days.
Q:Why from the beginning of cantilever beam pouring cantilever end?
General joints are the final processing, in accordance with this principle, you can infer the front end (Yuan Duan) pouring, and finally deal with the old and new material seam problem
Q:Is there any paperwork and forms a traveler from USA to Dubai should look into?
You do not need any paperwork if you travel to Dubai. USA citizens do not need visa for Dubai. You can just go trough the immigration and they will give you a visitor visa for 30 days.
Q:The definition of hanging basket construction, historical background
Construction craft: 1 hanging basket hanging void, at this point the anti force downward force to the hanging beam hanging basket, hanging basket and the longitudinal beams under negative bending moment. 2 hanging basket forward, hanging basket still bear negative moment, a single arm state. 3 hanging basket beam lifting, after anchorage anchorage, the hanging basket is in place, after the anti point elevation roughly leveling, set preraised height. The 4 cable is connected with the hanging basket, and the first cable tension is carried out, and the front pivot point of the hanging basket is stressed. 5 to the 1/2 beam section for the second cable tension. When the concrete beam of the 6 section is completely cross section, the elasticity of the end of the basket is less than the specified value. 7 detect the beam elevation, the concrete strength to reach the tension of prestressed beam. 8 hanging basket to be moved forward.
Q:Can the vertical prestress of the hanging basket be tensioned after the subsequent section construction?
In order to improve the service performance of prestressed structure, during the construction to the structure of pre applied stress structures of pre compressive stress can be wholly or partially offset load caused by tensile stress, avoid structural damage. Commonly used in concrete structure, concrete structure under load is before, in advance to put pressure on it to make it in the outside load when the concrete tensile stress compressive stress produced in order to offset or reduce the load due to the tensile stress, the structure in the case of normal cracks or crack late.
Q:Management measures of hanging basket
The 3#~10# box girder of the bridge is hanging up and down vertically, so the safety management is more important. In the implementation of safety management, focus on the following work:
