Further technology: the prefabricated assembled arch ring is left and right symmetrical two-part structure, and two parts connector uses tenon The docking of fourth of the twelve Earthly Branches card slot.
Further technology: the top of the prefabricated assembled left and right symmetrical two-part structure of arch ring is respectively equipped with prefabricated Assembled arch ring built-in fitting and prefabricated assembled arch ring bear down on one attachment beam hanging plate, prefabricated assembled arch ring built-in fitting and prefabrication and assembly construction Formula arch ring, which bears down on one, to be equipped with prefabricated assembled arch ring between attachment beam hanging plate and bears down on one attachment beam hanging plate connector, described prefabricated assembled The prefabricated assembled arch ring on the top of the left and right symmetrical two-part structure of arch ring, which bears down on one, is equipped with prefabrication and assembly construction between attachment beam hanging plate The cast-in-place attachment beam that bears down on one of formula arch ring.
Further technology: the prefabricated assembled arch ring is monoblock type arch ring.
Further technology: the bridge floor setting water shutoff layer prevents from penetrating into filler under water.
Further technology: the backfill expects that drainage blanket is arranged close to panel side, the unexpected lower water seeped is discharged in time.
Further technology: ditch is set at the concrete foundation and ground.
Further technology: the panel is armored concrete panel, prefabricated plain concrete building block or dry-pressing stone imitated building block.
Using utility model has the advantages that bracket and template are eliminated, using industrialized production, scene sliding construction Installation does not need complicated connection, easy construction.The structure uses reinforced earth technology, effectively reduces soil body load, so that knot Structure is light-dutyer, and structure connection is simpler, constructs convenient for rapid assembly, reduces bumping at bridge-head risk, save engineering Investment, improves operation comfort level.
Detailed description of the invention:
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings;
Fig. 1 is industrialization reinforced earth arch bridge structure three-dimensional figure;
Based on Fig. 2 and arch ring cross-sectional view;
Fig. 3 is reinforcement cross-sectional view;
In figure: 1-concrete foundation, 2-prefabricated assembled arch rings, 3-panels, 4-muscle materials, 5-backfill material, 6-is broken Slip draw-in groove, the prefabricated assembled arch of 2-1-are reserved in stone drainage blanket, 9-bridge floors, 10-gutters, 11-ground, 1-1-basis Circle sliding Tenon card slot, the prefabricated assembled arch ring built-in fitting of 2-2-, the prefabricated assembled arch ring of 2-3-bear down on one attachment beam hanging plate, 2- 4-prefabricated assembled arch rings bear down on one attachment beam hanging plate connector, the cast-in-place attachment beam that bears down on one of the prefabricated assembled arch ring of 2-5-.
Specific embodiment:
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described implementation Example is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field Those of ordinary skill's every other embodiment obtained without creative efforts, belongs to the utility model The range of protection.
