The system is in practical application, specific erection method is:
(1)Tower crane is completed by tower with suspended cable assembly pier.
(2)During pylon parts assembling, dissipate and spell according to underground, the principle of top assembling.Universal rod body is used on ground by two Root drum steel column is linked to be entirety.According to standard knot length, every 10m or the main pier tower crane of mono- section of use of 8m are successively installed upwards.Often One layer of standard knot is installed, is drawn according to design requirement and sets guy.And timely use steel pipe connecting clone be laterally attached stabilization.
(3)After the complete first segment of pylon parts assembling, first layer guy is installed, adjusts pylon perpendicularity, loosens facing for bearing When support, tensioning first layer guy to design Suo Li.Continuous assembly second section column, installs second layer guy, and be stretched to design Suo Li, loosens first layer guy.Until pylon assembly is completed.Interim guy is pricked screw-thread steel using steel strand wires and essence and is combined with each other, The pylon end of steel strand wires uses P anchors lower end for intermediate plate anchor, and sets locking device, is easy to operate, and guy is finely tuned in work progress Screw-thread steel is pricked with essence to adjust, two purlins should synchronously be carried out during adjustment.Assembled interim guy upper end steel strand wires, screw thread is pricked in lower end with essence Steel.
Hoist cable hanging cable, pretension, initial tensioning are carried out according to construction speed.
<1>Hanging cable
A. tower with suspended cable assembly is finished, and is casted anchor case arm-tie in the fraising engagement of girder steel connecting plate using the traction of 50t tackle pulleys, is inserted Enter hinge.
B. cable factory is manufactured and cable wire qualified by inspection, hangs on the front and back position for winding up design node, put rope Tiling, unnecessary sling length can be momentarily placed on bridge floor.
C. with single tower crane end 1.0 ~ 1.5m of anchor head of tower crane, anchor head is fed into upper anchor case rope hole, arc is put on Pad and nut, unclamp suspension hook, hang next, per totally 12 hoist cables before and after purlin, can before and after it is symmetrical, after upper end is all hung, then hang Lower end anchor head.
D. first rear rope cast anchor case install traction tensioning equipment(Including jack, tensioning nut, draw bar and connection Device), provinculum is extracted into anchor case rope hole by root with 10t reversible chain blocks or tackle pulley and attached the names of pre-determined candidates, rope pulling equipment after simultaneous tension, with flat Weigh horizontal force, controls tower top displacement, forward and backward rope anchor head nut installs two purlins should be synchronous, and forward and backward rope is installed(Attach the names of pre-determined candidates)After the completion of rope Anchoring temporarily.
<2>Pretension
With 2 hydraulic jack tensioning operations in each case that casts anchor.All around totally 4 casees that cast anchor are same for tower with suspended cable Walk operation, balanced, symmetrical tensioning pretension.Suo Li can not one-time-reach-place, should by 10~15t every time be incremented by tensioning by turns.Hoist cable tower Frame pretension is finished, and the stable guy of pylon assembly is loosened.
<3>Tensioning
A. tensioning
With 2 hydraulic jack tensioning operations in each case that casts anchor.All around totally 4 casees that cast anchor are synchronous for tower with suspended cable Operation, balanced, symmetrical tensioning.Tower with suspended cable is after tensioning operation, and girder steel can continue semi-girder and install until steel truss girder span centre.
B. rope is adjusted
Accurate measurement one searches high and low for power after hoist cable tensioning, is once finely tuned according to measurement result, and the Suo Li errors after fine setting should be controlled System is within ± 2%.Sarasota frame is adjusted after opening and adjusting rope, girder steel can continue cantilever erection until span centre.
(5)Cable force adjustment is carried out to hoist cable according to monitoring data, line style at the closure of girder steel front end is adjusted to design attitude, Carry out closure section installation.
In a word, the system carries out assembled be made using standard pylon component, it is possible to achieve tower with suspended cable unity of form, specification Unanimously.Its not only structure type simple type identifier, integral rigidity is big, and install convenient, it is intended to which it is various informative to solve tower with suspended cable, rule The problems such as lattice differ, it is applied to large-scale steel truss arched bridge, multispan freely-supported or the large steel girder such as continuous.
