The explanation of the each parts of highway bridge of the present embodiment:
The first, the present invention has abandoned tradition and has dug bridge foundation, quantities is large, and cost is high, is applicable to the bridge pier and abutment of permanent bridge engineering, the bridge pier and abutment that adopts easy installation and removal, this bridge pier and abutment comprises for fixed abutment and is positioned at the first steel plate under bridge pier; Under described the first steel plate, be provided with the steel column that welds mutually with the first steel plate and for inserting road surface, the first steel plate and road surface are fixed, on the first steel plate, be also provided with the rivet the first steel plate and road surface being fixed for inserting road surface. Wherein, the cylinder quantity on the first steel plate is indefinite, specifically determines according to actual conditions, and quantity can be 6,9,12 etc. But rivet on the first steel plate is positioned at the surrounding of the first steel plate, quantity can be determined according to actual conditions, is generally more than ten, for fixing more firm, can increase the quantity of rivet and steel column. But bolt quantity on the second steel plate also can determine according to actual conditions, the present embodiment has been installed 16 bolts, the quantity that user can be concrete according to the Location of requirement of oneself.
This bridge pier and abutment construction is as follows: on road surface, punch, concrete hole count is identical with the steel column quantity on the first steel plate, and aperture should be greater than steel column external diameter slightly, with placing concrete in backward hole, again by the steel column patchhole on the first steel plate, then use rivet the first steel plate and road surface to be fixed to (will guarantee the first upper surface of steel plate and road surface keeping parallelism), after concrete reaches prescribed strength, just can be arranged on bridge pier (bridge pier is by the second steel plate being connected by bolt with the first steel plate and be arranged at the second steel plate top and form with the support column that the second steel plate welds mutually) is installed on the first steel plate, workmen only need be fixed on the second steel plate on the first steel plate by bolt. when dismounting, only need the second steel plate be separated with the first steel plate by bolt, just can easily bridge pier and abutment be removed, it is extremely convenient to operate. utilize bridge pier and abutment of the present invention, avoided need on road surface, excavating larger foundation ditch before construction, cause the phenomenon of road surface extensive damage to occur, avoided affecting vehicle on road surface, pedestrian's safe passing simultaneously. but in the time that needs are removed bridge, bridge pier and abutment of the present invention also can be removed faster, make road surface recover original looks.
The second, the present invention adopts box beam body to replace conventional concrete pontic, thereby in concrete layer, increases embedded bar strengthened beam body intensity; In concrete layer bottom, the first metallic plate with the first screwed hole is set, to realize Fast Installation, the quick-detachment of box beam body with Bridge Beam architecture; Meanwhile, in concrete layer surrounding, the second metallic plate with the second screwed hole is set, thereby realizes box beam body with Fast Installation, quick-detachment between bridge extension joint. Feature: lightweight, lifting easily, Fast Installation, quick-detachment, be easy to maintaining, can reuse.
Three, traditional bridge extension joint belongs to semi-permanent structure, thereby use welding to realize and being connected with pontic with concreting, difficult maintenance, difficult replacing, installation duration, the bridge extension joint that the present invention adopts uses bridge extension joint connecting plate to replace reinforcing bar part in traditional bridge extension joint, increases between rubber mat plate increase pontic simultaneously and allows side-play amount. Feature: bridge extension joint of the present invention have easy installation, stability high, be easy to dismounting, recycling, in the construction of light-type bridge utilizes, more significantly embodied " recycling fast, " feature of bridge.
Four, traditional bridge only has a girder between two bridge pier and abutments, by the pontic of having manufactured be directly lifted into bridge floor carry out assembled, by girder power transmission to bridge substructure; Bridge Beam architecture of the present invention by crossbeam (also claiming girder), longeron, side bar overlap, assembled, increase the contact-making surface between box beam body, ensure the stability of the box beam body that more traditional beam body is less, box beam body can be delivered to load and self gravitation on crossbeam by longeron, side bar, is being delivered to bridge substructure by crossbeam. Feature: this Bridge Beam architecture in the time bearing the less box beam body of size, have practicality, stressed more evenly, power transmission is more reasonable. In the time building and remove, also expect simultaneously convenient, fast, safeguarding, while changing its parts and box bridge beam body convenient easily.
The course of work of the present invention:
1, the segmentation of novel road bridge is manufactured, segmentation transport, Assembling;
2, the reserved bus zone in novel road bridge both sides, heavy vehicle road, to alleviate bridge burden;
3, novel road crane span structure is established and is started from encircling and hunting down outside region on normal passing road, when work, bridge on part dilly, pass through in public transport, heavy vehicle both sides, upper bridge vehicle through climb and fall section, through guide section, enter active section, again through guide section, enter climb and fall section, finally pass through construction area;
4, when novel road bridge is removed, segmentation is removed one by one, is transported to and reclaims or the next place that need to set up.
According to above-described embodiment, just can realize well the present invention. What deserves to be explained is; under prerequisite based on said structure design, for solving same technical problem, even if some that make in the present invention are without substantial change or polishing; the essence of the technical scheme adopting is still the same with the present invention, therefore it also should be in protection scope of the present invention.
