2 reserved holes shall be accurate and shall not be allowed to bend.3 the pre tension of the hanging basket should be set according to the design.4 anchor bolts to be tightened by means of jack.5 the outer side of the mold at the anchor plate do not pack dead.6 when you walk in the basket, be sure to move smoothly.7 cantilever pouring concrete should be from the basket to the front of the basket to the end of the basket.8 jack is an important tool in construction, must be carefully maintained.9 walking system should be lubricated regularly.
The construction of a steel cable-stayed bridge, most of the factory welding process, transported to the site, with the crane as a whole lifting, or block lifting, in place after the formation of high-strength bolts.Two construction of concrete cable-stayed bridge with cast-in-place and precast assembly and other combinations of construction technology. 1 the installation elevation of the hanging basket should be in strict accordance with the designed value.
Short platform composite hanging basket construction: short platform composite hanging basket by hanging basket platform, tripod and servo system (including cable system, suspension system, walking system, anchorage system, horizontal support system, fine positioning system) three parts. As shown in the construction of the main girder section, under the condition of the front suspension and the pull rope, it must ensure that the front boom is under tension, and the tension value must be within the scope of the design. To install the dynamometer. Self-propelled front fulcrum hanging basket construction either truss or cable-stayed type are the fulcrum of form for the widespread use of cantilever hanging basket, the basket is a single cantilever force under negative bending moment is large, so the concrete segment length limitation. The front pivot hanging basket can make full use of the action of the stay cable and the negative moment of the cantilever is the force of simply supported positive bending moment. The pouring length and bearing capacity can be greatly improved. 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.
