Q:Short platform pull rope type hanging basket

The construction scheme for main bridge superstructure: installation of steel pipe column bracket in the cap on the box girder construction 0, No. 1 block on the bracket; 0, 1 complete block construction after the erection of rhombic hanging basket, piecewise symmetric cast until the completion of the No. 18 block construction (including 7 ~ 17 block cable block), forming the largest cantilever structure of T, and then by the side span to middle span by span symmetric closure.

Q:Is hanging basket equipment special equipment? Need to record it?

Special equipment regulations on safety supervision of special equipment is the safety of life, the risk of large boilers, air compressor and the air storage tank, tunnel construction hoisting machinery (construction elevator, tyre crane, crawler crane, gantry crane, tower crane, bridge machine), hanging basket construction equipment etc..

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:What is the meaning of "hanging basket" in building construction

Hanging basket, also known as "hanging basket", is a kind of tool without scaffolding for the construction of exterior wall.

Q:Management measures of hanging basket

12.1. re education. In the hanging basket construction, pay close attention to all the technical personnel of the technical disclosure and security. Everyone pays attention to safety management. Safety education 1 security inspection system form 012.2. hat. Hanging on the construction site, the line of life and safety, safety and happiness linked to two banners. And hanging into the site must wear helmets warning signs 0

Q:Hanging basket construction which test items

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

Q:Continuous beam bridge hanging basket construction post tensioning method, prestressed tension also need to measure the strain value?

Construction technology of concrete cable-stayed bridge with cast-in-place and precast assembly and other combinations.

Q:After the completion of prestressed tension grouting on the basket can move forward

Therefore, it is necessary to strictly control the grouting process. Do not allow the prestressed tension after the completion of the grouting on the basket forward. In reality no grouting on the hanging basket forward without accident, mainly due to the design is conservative, safety factor and other factors, to ensure the normal operation of the structure, however, once appear quality accident, it will investigate the problems existing in the construction.

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:T type steel bridge, the river, river on both sides of the main girder by cantilever pouring symmetrical design, no clear requirements,

The comprehensive understanding of asphalt pavement construction, road design, highway bridge design and construction, and the design and layout of highway related facilities deepen our understanding of the curriculum knowledge and make the practice of combining
