UNCONVENTIONAL RHOMBIC FORM TRAVELLER

Brief Introduction

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..

Advantage

● 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: A set of hanging basket refers to the symmetry of the left and right two hanging basket or a single hanging basket?: Through longitudinal prestress and longitudinal reinforcement connection

Q: Car hanging basket, green, yellow different license, according to what standard hang: Special vehicles: white red black; make,Consulate foreign car: black white and red "to" sign;Other foreign car: black white.

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: What are the key processes of hanging basket construction: 5, construction of prestressed beam shape control; 6, 7; and the closure above and the construction of system transformation are met according to arrangement of students problems in practical work and, for reference, if there is a problem, please timely communication.

Q: On the problem of the hanging basket preloading procedure? Construction of the two main piers, the progress of the first, the previous one to hang the basket pre pressure, then the second need to pre pressure?: Install side span closure section, installation of hanging mold closure segment skeleton, formwork, steel banding, installation of prestressed pipe and the core concrete pouring, side span closure segment and maintenance - tension closure segment longitudinal, transverse and vertical prestressed grouting, removing the side line and cross - - side span closure segment construction support the landing gear box girder.

Q: Summary of the hanging basket construction: 2 the girder structure system of the main girder structure system can be divided into four different systems according to the combination of the girder tower and the cable tower:Floating system: Tower Pier tower girder girder consolidation, separation, in addition to support at both ends, all the rest of the cable suspended, this system does not provide effective support for the transverse beam, to the temperature shrinkage and creep force structure, the cross section deformation and internal force changes smoothly, uniform stress, but must be in the cantilever construction in the tower at the temporary consolidation.Support system: Tower Pier tower girder girder consolidation, separation, set the vertical support in the tower, a three span continuous beam or cantilever beam with elastic support, the latter is in a cross hinge or a hanging hole, a hanging hole to a certain length, in order to avoid the side load, resulting in hanging hole excessive tilt.Tower beam consolidation system: the tower beam is fixed and supported on the pier, the stay cable is an elastic support, which can be used for continuous beam or cantilever beam.Rigid frame system: the beam pier is mutually consolidated to form a rigid structure with multi point elastic supports.3 overview of cable-stayed bridge construction process: the construction of cable-stayed bridge erection method in general there are three common methods: support method, push method and cantilever construction method. The first two methods used in the early construction of cable-stayed bridge, the cable-stayed bridge grew up in modern, especially from the tower to the cantilever construction on both sides of the multi span cable-stayed bridge with missile, inclined cable segment support.

Q: Operating rules for hanging baskets: The above adjustment process, on-site construction management personnel and engineering and technical personnel must grasp the seven technical problems o A1 pay attention to the relationship between the turning point elevation, to coincide with the design of 2B1 through the side of the mold bottom to adjust the tension screw

Q: Can you please list them ALL because I really need it for my book report =) thanks: Dasher, Dancer, Prancer, Vixen... er, no, wait Happy, Sleepy, Dopey, Sneezy... er, no, wait sorry, I never read it, maybe YOU should

Q: The construction of the hanging basket of the bridge needs to be pre - pressed in each suspension section: . After the completion of the construction of this paragraph, the hanging basket symmetrical move forward a section, the next beam section construction, progressive, until the cantilever beam section of the pouring completed.

Q: Hanging basket installation, removal of dangerous source identification: In practice, control and management of the hidden dangers of accidents and hazards of always together, because there is no hidden danger is not to control it; and to control the dangerous source, is to eliminate the hidden dangers of accidents or prevent the accidents. Therefore, in practice, sometimes the use of these two concepts are not the same.
