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: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:How to evaluate the construction scheme of bridge hanging basket: For example: 1 you choose the form of hanging basket to meet the design requirements2 is there any difference in the reliability of the bridge design

Q:Hanging basket concrete pouring construction control points: Management points:1 the concrete pouring on both sides of the beam should be symmetrical and balanced, and the unbalanced construction load should not be greater than the allowable value;2 concrete should be rapid, continuous construction, in the first pouring of concrete before the first pouring all completed;3 the bottom plate, the web and the roof are symmetrically layered, and the layer thickness should not be greater than 30cm;4 continuously change the height of the hanging basket in the process of concrete pouring;5 the quality of the installation of the prestressed channel, unobstructed inspection and plugging treatment;6 the vibration of concrete should meet the requirements of construction technology, it is appropriate to use high-frequency attachment vibrator with vibration;7 the temperature and air content of concrete in mold meet the design requirements;8 test specimens of concrete strength and elastic modulus.

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:Construction of hanging basket hanging blue construction: 1, should hold a special type of work permit;2, before the job requirements for safety technical disclosure;3, simple and flexible clothing, wear non slip shoes;4, is strictly prohibited drink posts;

Q:The construction of the hanging basket is not every section of the pre pressure: The construction of the hanging basket is not the pre pressure of each section.Hanging basket construction steps are as follows:

Q:Hanging basket construction continuous beam, the adjacent fast is how to connect, such as Block 0 and block No. 1: 3, installation of connecting two adjacent segments (such as 0# and 1#, 0# and 1 "#) corrugated pipe hole, and wear long (such as 1# to 0# to 1" # through wearing steel strand).

Q:You know how space travelers are astronauts and time travelers are crononauts? Well, what is the naut form of an inter dimensional traveler? (Obviously in fiction).: Internaut? ;) I don't think one exists yet. You could try making it up. If Cosmos is the universe and inter-dimensional travel is travelling between different parallel universes, maybe it should be Cosmonaut (though the Russians already took that one...)

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:Construction of extra large bridge: 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.
