Description
Technical field
The present invention relates to suspension bridge construction field, the construction method laid particularly to a kind of suspension bridge cat road.
Background technology
Cat road is the temporary structure that suspension bridge construction is indispensable, construction operation platform, material and instrument transport channel is provided for the installation of main cable erection, cord clip and hoist cable, steel box-girder lifting, main cable protection etc., its use from start to finish runs through whole suspension bridge superstructure installation process, and cat road surface layer is made up of bearing net, sneakernet and the anti-skidding lumps of wood.
The laying of tradition cat road surface layer
After cat road track cable and cat road door frame track cable set up, sag adjustment completes, carry out the laying operation of cat road surface layer.Cat road surface layer uses downslide laying method.Before laying cat road surface layer, on cat road work platforms, at track cable lm, set up a work platforms, deposit cat road surface layer net.On ground by the various materials of composition cat road surface layer, such as anti-skidding batten, asperities layer net etc., carry out colligation by design attitude, with tower crane, surface layer net winched to tower top work platforms, then the shaped steel crossbeam needed for topping laying, U bolt etc. are hung to tower top work platforms.Interconnection and counterweight deadweight is utilized to drive veil to glide.Treat that interconnection and counterweight install, by tower top work platforms, lay surface layer net.With U-bolt by veil and shap steel on cat road track cable, to guarantee that surface layer on track cable slidably can often lay one section of surface layer, i.e. glide a certain distance, re-lays another Duan Mao road surface layer, is so recycled to cat road and closes up.
The shortcoming that tradition topping laying exists:
1, use the construction of downslide laying method need to set up platform, increase operating expenses and put into.
2, hanging device lifting cat road surface layer net, increases crane gear expense and puts into.
3, setting up platform and deposit cat road surface layer net, storage area is limited.
4, tower end operation, potential safety hazard is bigger.
Summary of the invention
The technical problem to be solved is the construction method providing a kind of suspension bridge cat road to lay for above-mentioned prior art, and safe and reliable, operation is simple, reduces work high above the ground risk, there is not cross-operation phenomenon and the problem of regional space limitation simultaneously.
The present invention solves the technical scheme that the problems referred to above are used: the construction method that a kind of suspension bridge cat road is laid, and said method comprising the steps of:
Step one, erection cat road track cable
Between the rope frame tower of suspension bridge, set up cat road track cable, the perpendicularity of track cable is adjusted；
Step 2, installation operating platform and power-equipment
Install hanging basket at track cable distance bridge lowest part, required equipment is placed in hanging basket, installs hoist engine simultaneously, utilize hoist engine to carry out the laying of cat road surface layer；
Step 3, the making of cat road surface layer steel fabric sheet unit
Stack fixing by shaped steel by upper and lower to a piece of little side's eye steel fabric sheet and a piece of generous eye steel fabric sheet in hanging basket, U-bolt is set on shaped steel simultaneously two panels mesh sheet is locked with shaped steel, make steel fabric sheet unit；
Step 4, the laying of steel fabric sheet unit
A piece of steel fabric sheet unit step 3 kind made is placed on track cable, U-bolt is stuck on track cable, connected with the shaped steel on mounted steel fabric sheet unit by steel wire rope of windlass, then utilize hoist engine take-up that mesh sheet is moved on rope frame tower end along track cable, often move a piece of steel fabric sheet cell distance, by steel wire, the shaped steel on newly installed a piece of steel fabric sheet unit is connected with front a piece of shaped steel, completes the laying from the bottom to the top of cat road surface layer steel wire in this way；
Step 5, anti-skidding plank are laid
The cat road surface layer steel wire that step 4 has been laid carries out the laying of non-slip wood plate, anti-skidding plank is fixed together with head-rope, thus complete the laying in whole cat road.
Compared with prior art, it is an advantage of the current invention that:
1, anchor road minimum point is hung and is set construction hanging basket, there is not cross-operation phenomenon.
2, hanging basket is as operation platform, safe and reliable, and operation is simple.
3, the lifting of anchor road minimum point surface layer net, not domain of the existence limited space.
4, hanging basket is installed at the lowest part of track cable, reduces work high above the ground risk.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Fig. 1 Fig. 3, the construction method that a kind of suspension bridge cat road in the present embodiment is laid, this construction method changes traditional down-sliding type laying method from high to low, uses the pull-up laying method hoisted by lower, and the method mainly comprises the steps that
Step one, erection cat road track cable
Between the rope frame tower of suspension bridge, set up cat road track cable, according to practical situation, the perpendicularity of track cable is adjusted, it is simple to the laying of follow-up cat road surface layer.
Step 2, installation operating platform and power-equipment
Utilizing support to install hanging basket at track cable distance bridge lowest part, utilize crane gear lifting to be placed in hanging basket required to steel fabric sheet, anti-skidding plank etc. equipment, hanging basket is heap material platform, is again the operating platform installing steel fabric sheet with anti-skidding plank；On the rope frame tower of both sides, it is respectively mounted hoist engine simultaneously, utilizes hoist engine to carry out the laying of cat road surface layer.Here hoist engine can also be laid on the ground, installs pulley assembly on rope frame tower simultaneously, and the steel wire rope of hoist engine is connected with steel fabric sheet after walking around pulley.
Step 3, the making of cat road surface layer steel fabric sheet unit
Cat road surface layer steel wire includes being positioned at the bearing net being made up of generous eye welding wire mesh sheet of bottom and being positioned at the sneakernet being made up of little side's eye welding wire mesh sheet on upper strata, workman in hanging basket by shaped steel by upper and lower to a piece of little side's eye steel fabric sheet and a piece of generous eye steel fabric sheet stack fixing, on shaped steel, arrange U-bolt two panels mesh sheet locked with shaped steel simultaneously, make steel fabric sheet unit.
Step 4, the laying of steel fabric sheet unit
A piece of steel fabric sheet unit step 3 kind made is placed on track cable, shaped steel is vertical with track cable, U-bolt is stuck on track cable simultaneously, to guarantee that surface layer can on track cable slidably, connected with the shaped steel on mounted steel fabric sheet unit by the steel wire rope of windlass of side, then utilize hoist engine take-up that mesh sheet is moved on rope frame tower end along track cable, often move a piece of steel fabric sheet cell distance, by steel wire, the shaped steel on newly installed a piece of steel fabric sheet unit is connected with front a piece of shaped steel, complete the half side laying from the bottom to the top of cat road surface layer steel wire in this way, the most half side adopting is laid in the same way, thus complete the laying of cat road surface layer steel wire.
Step 5, anti-skidding plank are laid
The cat road surface layer steel wire that step 4 has been laid carries out the laying of non-slip wood plate, workman from hanging basket on steel wire, carried out to both sides by lowest point, by steel wire or other locking devices, anti-skidding plank is fixed together with track cable, on the one hand anti-skidding effect when walking on cat road can be played, on the other hand steel wire can be pressed on track cable, thus complete the laying in whole cat road.
In addition to the implementation, present invention additionally comprises the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, all should fall within the scope of the hereto appended claims.
