It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the drawings.
The conventional steel pipe support method is a construction method commonly used for installing a steel structure bridge deck, a bridge deck system and arch ribs cannot be constructed and prepared at the same time, and when the support is not dismantled after the advanced bridge deck system is installed, the arrangement of an arch center is not directly realized because the inward inclination of the angle of the bridge deck system support cannot be used for arranging the arch center, so that the bridge deck system support needs to be dismantled and then the arrangement of the arch center support needs to be carried out; when the advanced arch support is arranged, the bridge deck support cannot be built on the premise of not dismantling the arch support because the arch support usually exceeds the height of a bridge body, and therefore the arch support needs to be dismantled. That is, the conventional steel pipe support method is a construction method commonly used for installing the bridge deck of the steel structure bridge, and the bridge deck system and the arch ribs cannot be constructed and prepared at the same time, so that the integral support cannot be arranged on the basis of the original mechanism arrangement. Therefore, the steel pipe support is complex in structure and consumes a large amount of materials and working hours when being disassembled and assembled in construction.
As shown in fig. 1, the application of the invention relates to a steel pipe support shared by a bridge deck system and arch ribs of a steel structure arch bridge, the steel pipe support shared by the bridge deck system and the arch ribs of the steel structure arch bridge is used for building a first support 1 of an arch frame and a second support 2 of the arch frame and the bridge deck system, the first support 1 and the second support 2 are structurally connected, the second support 2 is higher than the first support 1, a tie beam 4 is arranged at the joint of the top surface of the first support 1 and the second support 2, and an angle adjusting device for adjusting the inward inclination angle of the bridge deck system is arranged between the tie beam 3 and the first support 1.
In a preferred embodiment of the present invention, the first bracket 1 and the second bracket 2 are both steel pipe brackets formed by at least steel pipe piles, and in a further preferred embodiment, channel steel parallel links 5 and diagonal braces 6 for ensuring the whole steel pipe brackets are welded between the steel pipe piles. In a further preferred embodiment of the present invention, a steel plate is welded at the intersection of the steel pipe pile and the channel steel parallel connection 5 to serve as a connecting plate, so as to improve the stability of the overall structure of the steel pipe support.
In a preferred embodiment of the present invention, a total of 6 steel pipe piles are arranged at the bottoms of the first support 1 and the second support 2, each 2 steel pipe piles form a group, and 3 groups of steel pipe piles are arranged side by side, wherein 2 steel pipe piles located at the middle position are shared by the first support 1 and the second support 2, and the other 2 groups of steel pipe piles located at the two sides belong to the first support 1 and the second support 2, respectively.
In the preferred embodiment of the invention, because the supports need to be used in a turnover manner, the supports in the same group need to be manufactured into an integral structure in order to avoid material waste and influence on work efficiency caused by multiple cutting and welding during support dismantling.

When keeping away from second support 2's jack is higher than and closes on during the jack of second support 2, the tie beam is in the inboard slope under angle adjusting device's the drive, and then realize adjusting under the prerequisite of the technical effect of bridge floor system inclination angle, first support with the second support is overall structure design, has reduced steel pipe support's in the work progress dismouting process, has saved the material, has shortened man-hour.
The technical scheme of the invention can be implemented by the following specific construction method:
utilize DZ120 type pile hammer hammering steel-pipe pile to design position to guarantee that the whole atress of steel-pipe pile satisfies the designing requirement, it is preferred, the steel-pipe pile size is: the diameter is 800mm, and the thickness is 8 mm.
After the steel pipe pile is inserted and driven in place, the channel steel parallel connection and the inclined strut are welded to ensure the stability of the whole structure of the steel pipe support. A 10cm steel plate is welded at the crossing position of the steel pipe piles and the parallel connection to serve as a connecting plate, when channel steel parallel connection and inclined struts are installed, back clamping connection is carried out for welding and fixing, the channel steel parallel connection and the inclined struts among the steel pipe piles adopt 2[20a channel steel, and the scissor struts adopt [20a channel steel;
after the installation of the bearing beam is completed, the construction of the bridge deck system can be carried out by using the four steel pipe columns on the left side as the supports, and in order to ensure that the arch rib can also be constructed by using the support, the steel pipe piles on the right side and in the middle of the steel pipe support are connected to the designed position of the arch rib. And similarly, the channel steel parallel connection, the inclined strut and the bearing beam are arranged as stressed components. Because the supports need to be used in a turnover manner, in order to avoid material waste and influence on work efficiency caused by multiple cutting and welding during support dismantling, the same group of supports need to be manufactured into an integral structure, steel pipe piles are connected through flange plates, and the supports are specifically arranged according to material conditions during construction;
the integral support is used for high connection treatment, so that the steel structure arch bridge deck system and the arch ribs can simultaneously share one group of steel pipe supports for simultaneous construction and construction preparation.
