Description

Precast Reinforced Roadbed Rigid Wall Structure and Construction Method {STRUCTURE FOR PRECAST RIGID WALL OF SURFACE CONNECTION TYPE, AND CONSTRUCTING METHOD FOR THE SAME}

The present invention relates to the construction of reinforcement roadbed rigid wall, and more specifically, to the surface structure of forming a reinforcement roadbed rigid wall (Rigid Wall) having a flexural rigidity as an assembly structure of precast concrete panels (hereinafter referred to as PC panels) The present invention relates to a connection precast reinforced roadbed rigid wall structure and its construction method.

In the case of ordinary trains, unlike roads, the operating load is large and many passengers are transported at one time. In addition, since there is no detour, re-construction after construction of the earthworks will cause great inconvenience to railway operation. Therefore, the stability of railway structures should be considered, including the application of stringent quality standards to the residual settlement of the ground where the railway is constructed.

In the case of railway construction on embankment construction, loads are concentrated near the wall of the retaining wall due to the foundation of the train. In the existing reinforced earth retaining wall, if the concentrated load is applied, excessive horizontal displacement occurs on the back surface of the wall, and the reinforcing earth retaining wall itself may be destroyed. Especially, due to the introduction and construction of concrete track, it is almost impossible to maintain and repair after constructing the earthwork. In order to utilize the reinforced earth retaining wall structure, the deformation of the structure should be minimized.

 In the case of such a conventional reinforced earth retaining wall, a concentrated load acts on the wall of the retaining wall, or a voltage due to the compaction roller (horizontal earth pressure applied to the front wall of the retaining wall by compaction) So that it is difficult to prevent the front wall from being pushed forward. Accordingly, there is a problem that it is difficult to smoothly perform the compaction work just behind the front wall. Particularly, due to the lack of compaction work, the reinforced earth retaining wall often has a phenomenon that a part of the front wall protrudes locally, and the front wall is separated from the back ground by a structure type in which the tensile force of the reinforcing material can not be utilized sufficiently .

In order to prevent such phenomena, it is necessary to maintain the elasticity over the entire length so that the reinforcing material can exhibit its function. However, it is very difficult to solve the problem by the structure and construction method of the present reinforced earth retaining wall in which the front wall is installed first.

In addition, in the case of existing reinforced earth retaining walls, there is a problem in that it is difficult to install electric wires, noise walls, and the like because the structure is not structured to construct structures on the front wall. In addition, it is necessary to form work in order to install the on-site concrete when constructing a reinforced roadbed rigid wall. Such a formwork requires a long period of construction time, There is a problem that a separate work space necessary for installation is required.

The reinforced roadbed construction using the reference frame according to the related art uses a reference frame 60 as shown in FIG. 3B as a field-mounted reinforced roadbed construction method, and constructs and disassembles the formwork 80. At this time, (80) and the reference frame (60).

However, in the case of the reinforced roadbed construction using the reference frame according to the related art, there is a problem that the construction speed is slow due to construction and demolition of the mold 80, connection of the mold 80 and the reference frame 60, .

The base portion 210 is embedded in the ground, and the base portion protruding rebar 220 is formed in the vertical direction.

The fill body 110 is formed by sequentially stacking the fill layer at a position spaced apart from the rear surface of the reinforcement roadbed rigid wall 140 by a fill material between the fill body 110 and the reinforcement roadbed rigid wall 140. By constructing 150, the reinforced roadbed rigid wall 140 and the landfill body 110 are integrated.

The reference frame 120 is provided with a reference plate connection plate 122, and is a welded metal mesh installed when the fill body 110 is formed, to prevent the verticality and fillet outflow from the surface of the steep gradient, and during the construction and after completion of the construction Installed to ensure the stability of the fill body (110). In addition, as shown in FIGS. 9 and 10 to be described later, a male threaded protrusion 121 is formed on the main reinforcing bar of the reference frame 120 to be combined with a female screw formed on the reference frame connecting plate 122, and the reference frame The connecting flat plate 122 may adjust the horizontal position by measurement before lamination of the PC panel.

The PC panel 130 includes a flat duct 131 and a root plate 132, and is laminated and assembled with each other through the convex portions 133 and the concave portions 134 to form a reinforced roadbed rigid wall 140. It is connected to the reference frame 120 in a plane manner. Here, the vertical reinforcing bar formed in the planar duct 131, after the stacking of the PC panel 130, the reinforcement roadbed rigid wall (laminated with the reinforcing bar 220 protruding upward from the base portion 210) ( The bending rigidity of 140) can be secured.

As shown in FIG. 5, the planar duct 131 is formed inside the PC panel 130 for axial reinforcement continuity, so that the surface-type connection for connection with the reference frame 120 is formed on the rear side of the PC panel 130. The wife root plate 132 is installed. That is, the root plate 132 is a plane type connection portion, and is connected to the reference frame connection plate 122 in a plane manner to resist the displacement of the wall outside due to pour pressure and external force when the filler 150 is injected. Accordingly, regardless of the construction error of the PC panel 130 and settlement of the fill body 110, the PC panel 130 and the back-filling portion can be connected to have a planar connection structure.

Filler 150 is injected between the reinforced roadbed rigid wall and the fill body. The filler 150 induces the integration of the reinforcement roadbed rigid wall 140 and the fill body 110 and transfers the load applied to the landfill body 110 to the reinforcement roadbed rigid wall 140. In this case, the filler 150 may be a non-shrink mortar that integrates the reinforcement roadbed rigid wall 140 and the fill body (110).

Therefore, the surface-type connection precast reinforcement roadbed rigid wall structure according to the embodiment of the present invention, the fast solidification filler 150 between the reinforced roadbed rigid wall 140 and the landfill body 110 in which the PC panel 130 is laminated and assembled. Injecting) may induce the integration of the reinforced roadbed rigid wall 140 and the fill body 110 and transmit the load applied to the fill body 110 to the wall.

In the case of the surface-type connection precast reinforcement roadbed rigid wall structure according to an embodiment of the present invention, it is possible to ensure the homogeneity of quality due to the standardized pre-production of the PC panel 130, and to reduce the construction time. That is, since the reinforced roadbed rigid wall 140 is formed by the PC panel 130, the formwork is unnecessary and the construction period can be shortened.

In addition, it is possible to improve the workability by the free connection method for construction errors and sediment settlement, and to ensure the flexural rigidity of the reinforced roadbed rigid wall by sequencing by the overlapping of the vertical bars.
