Abstract
The invention discloses an installation method of towing cable hanging baskets. The installation method comprises the following steps that firstly, a support for temporarily bearing the load of a bridge is built, a cast-in-situ beam section is poured on the support, and a sliding track is installed beside a main tower; secondly, the two hanging baskets are assembled on the sliding track, wherein the hanging baskets can slide along the sliding track; thirdly, the support is demounted after the cast-in-situ beam section reaches the tensioning strength, and one end of the sliding track penetrates through the main tower and extends to the ground projection position of the installation position of the hanging basket on the other side; fourthly, the two hanging baskets slide to the ground projection positions, below the main bridge, of the installation positions of the two hanging baskets respectively; fifthly, the two hanging baskets are integrally lifted to the installation positions of the hanging baskets. By means of the method, aerial work is transformed into ground work, and thus construction risks are reduced; hanging basket assembling and bridge construction can be synchronously conducted, and thus the project period can be shortened.
Description
Technical field
The present invention relates to CONSTRUCTION OF CABLE-STAYED BRIDGE technical field, be specifically related to a kind of mounting method of dragging suspension basket.
Background technology
Dragging suspension basket utilizes to wait that the section of building suspension cable provides supporting force as Hanging Basket front fulcrum, Hanging Basket rear end is anchored at casting beams section, for cantilever cast-in-situ prestressed concrete cable stayed bridge, bear beam body own wt and construction load and the construction equipment that can move forward piecemeal.
The construction method of installation of dragging suspension basket of the prior art is: build the support for interim bearing bridge load beam, and on support after cast-in-place 0# block (or 0# block and 1# block), striking, the assembled dragging suspension basket in below, is then promoted at the bottom of beam and installs.
There are the following problems for above-mentioned construction method: the Cast-in-situ Beam section such as 1, to need reach stretch-draw intensity, complete the work such as stretch-draw mud jacking after striking, then could start assembled Hanging Basket, the duration is longer, add Cast-in-situ Beam section and follow-up cantilever casting beam section poor for the length of time; 2, during cradle assembly, main girder construction is stagnated, and causes personnel and the idleness of equipment, increases construction cost and drops into; 3, because dragging suspension basket component is more, single-piece lifting machine is long for service time, and risk is high, and after support removing, will again clear up assembled place; And according to hawk frame method construction, then increase workload and input altogether.
