Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure and a reinforcing method for reinforcing a water-mounted structure, and more particularly, to a reinforcing structure capable of observing a state of a concrete structure installed by a reinforcing operation To a structure for reinforcing an underwater installation structure and a reinforcement method.
There is a known method of making bridge piers by using a paddle filling method using a paddle to construct a pier in the process of extending a bridge.
Generally, the shape of the pail used in the pail filling method is to use a steel plate form. That is, the basic right and left water mold formwork is divided into an inner steel formwork and an outer steel formwork to form a metal steel plate, and an angle is provided between the inner steel formwork and the outer steel formwork to function as a tensile material. .
In case of constructing bridge pier by filler filling method, inner iron plate form is completely buried in concrete because it pierces concrete between inner plate form and outer form plate form.
When metal plate formwork is used, the outer plate form is oxidized little by little (approximately 0.9 mm or so) in the water every year, and the thickness thinning phenomenon is intensified and the corrosion of concrete is accelerated according to the elapse of time. In particular, in the water source waters, such iron plate forms an oxidizing action and discharges a large amount of harmful substances containing iron, thereby becoming a source of pollution in the water source. Further, the strength of the pier structure is gradually weakened due to the progress of corrosion, have.
Therefore, if the oxidation phenomenon or the corrosion of the structure caused by the corrosion of the structure is detected, the underwater structure is reinforced. As shown in FIG. 1, the reinforcing method for a bridge underwater structure generally includes a step of forming a
However, since the
In order to solve these problems, a method of reinforcing the underwater installation structure is also developed by forming the form using the FRP special frame and placing the cone in the inside thereof. In this case, the FRP special frame is not removed unlike other formwork after concrete hardening, but it is used as it is installed on the outer side of cone structure to protect the cone structure safely.
However, since the FRP special frame is an opaque material, there is a problem that the state of the concrete structure inside the FRP special frame can not be observed. That is, it is difficult to visually confirm deterioration of the concrete structure inside the FRP special frame, whether cracks have occurred, or the like, as the use period elapses.
The object of the present invention is to provide a structure for reinforcing an underwater installation structure and a reinforcement method having a structure capable of observing the inner state of a concrete structure installed by a reinforcement operation while a reinforcement structure is reinforced by using a reinforcement structure .
According to an aspect of the present invention, there is provided a structure for reinforcing an underwater installation structure, the structure comprising: an FRP frame installed at a predetermined distance from the underwater installation structure and surrounding the underwater installation structure; And an internal check part fixedly installed inside the FRP frame to provide a space for checking the state of the concrete structure filled between the FRP frame and the modified installation structure.
In the present invention, the FRP frame may include an FRP wall plate portion formed of an FRP plate and an angular steel pipe fixed to the FRP plate, the FRP wall plate portion forming an outer surface of the FRP frame; A plurality of steel reinforcing parts provided in a space between the FRP wall part and the underwater mounting structure at a predetermined distance from the FRP wall part to reinforce the FRP frame; And a connection part connecting and fixing one side of the plurality of steel reinforcement parts.
In addition, the FRP wall plate part may be formed of a plurality of FRP wall plate parts having a cylindrical shape, a cylindrical shape or a rectangular tube shape in an assembled state.
It is preferable that the FRP wall plate part further includes a fastening part formed by bending the corner of the FRP plate inward and fastened by the fastening member to the adjacent FRP wall plate part.
In the present invention, the internal check unit may include a plurality of steel reinforcing parts, which are installed in the FRP wall part in a space between the plurality of reinforcing steel parts, And a through-pipe fixing part fixing the camera through pipe to the FRP wall part.
Further, in the present invention, it is preferable that the upper end of the camera passage pipe is installed higher than the upper end of the upper FRP wall plate portion.
Also, in the present invention, it is preferable that the camera through pipe comprises an acrylic pipe.
It is preferable that a plurality of the internal identifiers are spaced apart from each other by a predetermined distance.
According to the present invention, the underwater installation structure is structurally reinforced by the reinforcing structure of the present invention, and the specific reinforcing effect that the structural reinforcement is continued unchanged after the lapse of time after the construction is generated. Further, There is an advantage that the condition of the concrete structure inside the part can be easily confirmed.
