Q:Hanging basket construction and demolition of blue construction should meet the following requirements

(6) after assembling the basket, the installation quality should be checked, and the load test should be carried out in order to measure the deformation of the basket and eliminate the non elastic deformation. If the local deformation is too large in the pre pressing process, the load should be stopped immediately.(7) the removal of the hanging basket shall be removed in accordance with the requirements.

Q:Combined with the hanging basket pouring construction process, the 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: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:

Q:What is the bridge hanging basket through hole

Is the pier construction after the hanging basket construction of continuous beam structure!

Q:Hanging basket construction which test items

Motor, electric box, and limit are generally provided by manufacturers.

Q:Summary of hanging basket construction:

Pay attention to the influence of asymmetric force and wind force. The development of cable-stayed bridge in the direction of simplifying and reducing the construction machinery and equipment, strengthening construction control and management. Prior to the construction of the construction to do a detailed calculation, construction to strengthen the measurement analysis to adjust the construction.

Q:The definition of hanging basket construction, historical background

With the development of material science and computer science, a lot of cable-stayed bridges have been built at home and abroad since the Stromsun bridge in 1956 started the apex of modern cable-stayed bridge. The cable-stayed bridge has been developed rapidly because of its advantages such as large span, good structural performance, simple construction, easy maintenance, low cost and attractive appearance.

Q:In the construction of the bridge hanging basket, the temporary prestressing force is adopted in the closing section

Slightly under the pull, the clip is loosened, the jack to the starting point of less than the place on the clip

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:What's the meaning of the main truss in the basket?

H ngli ng trussThe [brace girder] is composed of a plurality of slats of the web and the two sides of the connection of the girder
