With reference to embodiment come the present invention will be described in detail create.
A kind of device applied in the construction method for promoting high pier large-tonnage steel bearing, as shown in Fig. 1 to 5, including with bridge
The pier top slideway 2 that built-in fitting 1 is connected and fixed on pier, the pier top for being adjusted to pier coping portion can be slid through slideway by, which being equipped on slideway, hangs
Frame 3；The pier top hanger is equipped with the hoisting mechanism 5 for driving 4 folding and unfolding of steel strand wires, and the steel driven in hoisting mechanism twists
Line lower end, which is connected with, promotes hanging basket 6.
A kind of construction method promoting high pier large-tonnage steel bearing using above-mentioned apparatus is provided below, includes the following steps：
1. (in fact, final section slow setting soil here refers to pier shaft before the final section concrete of bridge pier pier shaft of constructing
Topmost can also be the concrete edge joist at the top of pier shaft signified in the following contents), (press force analysis in design position
With selected position after design) at be arranged built-in fitting；
2. after pier shaft concrete construction, pier top slideway is installed on built-in fitting, and pier top is set up on pier top slideway
Hanger；In general, pier top sliding provides space for the adjustment of pier top hanger installation site, and the slideway as adjustment uses.Pier top
Slideway can be perpendicular to pier shaft setting, facilitate pier top hanger towards being adjusted on bridge pier (closer or far from bridge pier) direction
It is whole, to reach best using effect, also for the bridle iron of matching different size.
3. in pier top hanger over-assemble hoisting mechanism, steel strand wires are worn on hoisting mechanism, and by steel strand wires lower end and pier
Promotion hanging basket connection at the position of bottom；Above-mentioned hoisting mechanism generally may include vertical jack, using vertically arranged very heavy
The stretching motion on top realizes the lifting of steel strand wires.Specifically, can be by extension bar one end of jack upward, and stretching out
Fixed seat is arranged in bar top, and steel strand wires upper end is fixed in the fixed seat, by the flexible of jack, drives fixed seat or more
Movement, and then realize the lifting of steel strand wires, to realize the lifting of the promotion hanging basket to steel strand wires lower end.
It is promoted on hanging basket 4. bridle iron to be hoisted is placed in, manipulates hoisting mechanism and pull steel strand wires, bridle iron is carried
Rise to pier top position.Using above-mentioned lifting method for improving, large-tonnage steel bearing can be easily promoted, lifting process stabilization can
It leans on, also, the position by adjusting pier top hanger on pier top slideway, effectively avoids bridle iron from being collided with bridge pier, lifting process
It is reliable and stable.
It in addition, being promoted bridle iron to after pier top, can be adjusted, be realized by sliding of the pier top hanger on pier top slideway
Installation in place can be efficiently completed bearing lifting work, while saving construction cost using this method.
Spatial position is limited at pier bottom, it is difficult to which when storing the promotion hanging basket, in pier bottom position, setting is carried for storing
The pier bottom hanging basket holder 7 of hanging basket.Such structure setting, it is ensured that in the case of space is limited, carried carrying out bridle iron
When rising operation, hanging basket will be promoted and be stored on pier bottom hanging basket holder, without transferring to pier bottom portion again.
It should be noted that when being provided with concrete edge joist 8, above-mentioned steps 1. in design position at include actually
The edge of concrete edge joist.I.e., it is possible to be that slideway is fixed on the slow setting soil side joist of bridge pier, by concrete edge joist
Reliable support is provided, keeps stablizing.
Above-mentioned built-in fitting includes the steel plate for fixing pier top slideway, pier top slideway is reliably fixed by steel plate, together
When, above-mentioned pier shaft top is equipped with concrete edge joist, and the pier top slideway is fixed by the concrete edge joist support, can be true
Guarantor's pier top slideway is fixed, and the stretching top of pier top slideway is practical to provide reliable support force by concrete side bar, and structure is steady
It is qualitative good, will not unstability, promoted large-tonnage steel bearing when, entire operation process stationarity is good.
Above-mentioned concrete edge joist setting is several, is uniformly arranged centered on bridge pier center line, pier top slideway can be divided into
Left and right two parts are separately fixed on corresponding concrete edge joist, to keep the stability for the pier top hanger installed on slideway.
The method for improving that the invention provides, can safely and effectively carry out the promotion work of high pier large-tonnage steel bearing
Make, is particularly suitable for the case where field condition is not suitable for using heavy mechanical equipment.Meanwhile the structural portion involved in method for improving
Part can be repeatedly utilized so that, construction cost is greatly saved, and the Improve Efficiency that high pier large-tonnage steel bearing is joined for overlength is particularly bright
It is aobvious.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection domain within.
