[0002] Arch bridges are mostly used in urban and landscape design, and are also used to cross canyons and for mountain rafting. Top-supported arch bridges use a main arch ring, upper columns and a belly arch structure.

[0024] The present invention also proposes a method for using an arch ring formwork for supporting a super-high arch bridge, comprising the following steps: Step 1. First, design the bracket according to the construction drawings. According to the design plan and the support system plan, use a total station and a steel ruler to determine the position of the support base 1 made of concrete; chisel off the loose layer on the rock surface until the hard rock surface is reached, and the bottom is cleared and leveled before the temporary concrete pier construction can be carried out; the temporary pier is made of C25 reinforced concrete, with a length of 6.0m, a width of 1.0m, and a height of 0.3m. The site is leveled and the foundation is reinforced, and then the support base 1 is made by pouring concrete. After the concrete support base 1 is completely solidified, a nail column 16 is inserted into the connecting support protrusion 14 at the side end of the support base 1 to reinforce the support base 1, and then a support column 2 connected by a flange of multiple assembly columns 13 is installed on the upper end of the support base 1, and a support plate is installed on the top of the support column 2.

[0025] Step 2, then mark the position of the Bailey truss longitudinal beam on the support plate with paint, lift the installed Bailey beam 3, place it behind the installed Bailey beam 3, and make it in a straight line with it, two people use a wooden stick to pass through the node plate to lift the front section of Bailey beam 3, align the lower chord pin hole, insert the pin, and then lift the rear end of Bailey beam 3, insert the upper chord pin and set the safety pin, Bailey truss assembles single-layer double row on the ground, the assembled single-layer double row Bailey beam 3 is 24m long and weighs about 4.8t; single-layer three-row Bailey beam 3 and single-layer double row, single-layer three-row interval installation arrangement can be used in some reinforced areas, single-layer three-row Bailey beam 3 is 24m long and weighs about 7.2t; after the strength of the supporting base 1 reaches 100% and passes the inspection, the Bailey beam 3 is hoisted.

[0026] Step 3: Then, an I-beam 5 is fixedly installed on the upper end of the Bailey beam 3 as a distribution beam, and the spacing between the I-beams 5 is 60 cm. Then, a full-height bracket 4 is set up on the I-beam 5 to form an overall bracket system. The bottom mold 7 is installed on the full-height bracket 4. During the installation process, the height of the lifting threaded support rod 8 can be adjusted to better lift the bottom mold 7 that fits the arc, so that the bottom mold 7 can remain stable at different heights.

[0027] Step 4: In order to avoid the adverse effects of arch frame deformation on arch ring construction, according to the design drawing requirements, before the main arch ring is constructed, the support must be pre-stressed with a weight not less than the arch ring and the building on the arch to ensure that it has sufficient strength, rigidity and stability, and the construction pre-arch degree is set according to the construction load. Through the setting of the support base 1 and the nail column 16, the upper support structure can be more stably supported, and the support status of the support base 1 can be detected by the level detector 15, thereby preventing tipping during the pouring process; pre-stressed ton bags filled with sand are used as load test materials. The bottom area of ​​each cylindrical pre-stressed ton bag is 1.2m 2, height 0.8m, weight controlled at 1500kg, weighed with a scale; the pre-compression loading of the bracket simulates the working conditions of the actual pouring of the arch ring concrete. Within the full width of the arch ring, sandbags are stacked layer by layer and step by step from the arch feet on both sides to the arch top simultaneously and symmetrically. The sandbags are stacked and loaded in a uniform distribution manner.

[0028] Step five, finally, fix the retaining side plates 10 on both sides of the bottom form 7, and then insert the partitioning plug plates 11 between the retaining side plates 10 to separate the casting area, and then tie the steel bars and cast the concrete in the partitioned formwork. Through the setting of the anti-collapse groove 31 and the sealing gasket 28, the connection gap of the splicing formwork 18 can be blocked, so that the splicing formwork 18 can ensure the sealing of the connection while being spliced ​​with each other. Through the setting of the supporting spring 29 in the shrinking protrusion 27, the anti-collapse groove 31 in the shrinking protrusion 27 can be propped up, so that the shrinking protrusion 27 can better fit the splicing formwork 18 on both sides and prevent the top middle part of the shrinking protrusion 27 from collapsing under pressure. After the concrete solidifies, the construction can continue on the concrete arch structure. After the construction is completed, the formwork is removed, and the use of the device ends.
