Description

Incremental launching method (I.L.M) for Arch bridge structure using atemporary segment-supporter installed to substructureof bridge}

The present invention relates to an arch bridge construction method using a continuous extrusion method (ILM), and in particular, by forming a ground assembly site having a propulsion facility and a propulsion field corresponding to the bridge length on the bridge or extension of the bridge to be constructed Span bridge is constructed by extruding the completed cross-linked structure from the subassembly to the arch bridge construction site, and another arch structure assembled from the sub-assembly is extruded to be placed on the span bridge of the constructed cross-linked structure Arch bridges are formed by lifting the extruded arch structure upwards by lifting device and dismantling by feeding back the cross-linked structure to the paper assembly field and finally setting the arch structure raised by lifting device on both sides. Construction of the structure has limitations in the space of the geometry, Bypassing will also ensure that in providing the arch to fit in a limited area.

Road bridges constructed across roads, railways, waterways or rivers, valleys, farmland, and the sea can vary in length from 8 to 10m to 2000m long suspension bridges.

In general, bridges include MSS method, ILM method (Incremental Launching Method), FCM method, PSM method (Prestressed Concrete Beam Bridge), FSM method (Full Staging Method).

Among them, the continuous extrusion method (ILM) continuously manufactures the upper structure of the bridge (bridge bottom plate of various shapes made of concrete or steel, etc.) in the unit of segment at the manufacturing site (paper assembly site) located on the rear side of the shift ( And the horizontal compression force that can pass through the span of the bridge by the extrusion bridge and extrusion guide device such as vertical and horizontal jacks, with the nose connected to the front of the bridge. Completion of the bridge by launching a step of advancing one by one segment in the alternating direction in the state introduced into the segment structure by the tension method and repeatedly connecting the extruded top plate to another top of the segment unit It is a construction method.

The initial continuous extrusion method produced and extruded the upper girder segment of the entire length in the workshop with the length as long as the extension of the bridge. However, it took too much workshop and moved the upper girder segment to the predetermined position. The cost was excessively consumed and evaluated as not economical.

Since then, a teflon plate (sliding pad) with a very low coefficient of friction has been developed, and a pre-stressing method has been developed such as the introduction of prestressing to concrete upper girder segments, which has been applied to bridge construction until now. .

Since the continuous extrusion method (ILM) can be constructed without scaffolding, it is suitable for obstacles (roads, railroads, rivers, building protected areas, deep valleys), and construction cost for formwork is reduced according to the construction scale. There is. In addition, all-weather construction is possible regardless of climate by using steam curing and cover installation, and in case of long bridge extension, construction period is shortened.

In addition, the segment production and construction site is constant so that it can be repeated without construction delay, so it is easy to manage the process, and the segment production and the entire bridge construction work are cycled, so that the skilled work can be done with a few people, and the segment formwork is Fast assembly and disassembly, easy to manufacture molds with high degree of cross-sectional dimension, and all the processes are made in a certain place, there is an advantage that it is convenient to transport the material to streamline the work.

In addition, it is particularly economical when traversing deep valleys or streams, which are not easy to install, since it does not require the Dongbari hypothesis, and the bridge upper process is performed in parallel with the substructure process.

On the other hand, strict construction management is required when manufacturing a segment, and it is disadvantageous that it is restricted in the installation of the workshop because it is necessary to secure a workshop paper for manufacturing the segment at the rear of the shift or the rear of the first shift. In the case of workplaces crossing the congested highway area, it is not only difficult to control the vehicle, but it is also possible to secure a detour road due to overlapping reinforcement soils and adjacent constructions. There is an urgent need for a rational alternative method that is free of space and requires no additional steps such as securing a bypass.

Therefore, the problem to be solved by the arch bridge construction method using the continuous extrusion method (ILM) of the present invention, there is a difficulty in controlling the vehicle during the construction of the temporary construction in the intersection of the existing national road, highway, high-speed train, etc. The purpose of this is to construct the arch bridge in a reasonable way even if the detours are limited by overlapping reinforcement soil and adjacent construction.
