Description
The present invention relates to a precast concrete segment that can prevent breakage of an end portion and a method of manufacturing the same. More particularly, the present invention can prevent breakage due to contact between segments at the time of tunnel construction and improve corrosion resistance, The present invention relates to a precast concrete segment and a method of manufacturing the precast concrete segment, which can prevent breakage of the end portion, which can improve the economical efficiency, without the need of separately installing a joining device for joining the segments.
Generally, the segment is a piece (piece) used to form the inner wall of the tunnel excavated during construction of a tunnel called shield construction, and the precast segment is assembled in the factory after being manufactured at the factory. Which can reduce noise and civil complaints and shorten the working time, thus making it possible to shorten the construction period. An example of a technique for such a segment is disclosed in U.S. Patent Application Publication No. 2012-0127473 which discloses a tower segment in which reinforced concrete bodies are connected by joints.
However, in the conventional precast concrete segment described above, due to the jack thrust during the assembling process in the course of moving the member or in the field, the segments made of the concrete come into contact with each other, . In addition, conventional precast segments are vulnerable to chemical erosion during application of tunnels, waterways, drainage wastewater, and wastewater tunnels due to the properties of concrete.
In addition, the above-described conventional precast concrete segment must be provided with a steel material joining apparatus (bolt box) for joining the segments together in a manufacturing process in a structure that forms a wall surface of a tunnel. However, since the conventional precast concrete segment is manufactured by separately manufacturing a joining apparatus and then joining the joining apparatus to the segment, there is a problem that the manufacturing process is troublesome due to the installation of the joining apparatus and the cost increases accordingly.
It is an object of the present invention to provide a method of manufacturing a semiconductor device capable of preventing end breakage of a segment and improving the performance by being strong against chemical erosion and preventing breakage of the end portion, It is an object of the present invention to provide a precast concrete segment and a manufacturing method thereof.
According to an aspect of the present invention, there is provided a precast concrete segment comprising a plurality of segments disposed adjacent to each other to form an inner wall surface, the segment comprising a segment body formed of a concrete material and a protection member formed of synthetic resin material Provided is a precast concrete segment capable of preventing breakage of an end portion.
According to another aspect of the present invention, there is provided a precast concrete segment comprising a plurality of segments disposed adjacent to each other to form an inner wall surface of a tunnel, the segments being formed of a segment body formed by pouring and curing concrete in an arc shape, and FRP material, A plurality of coupling grooves for coupling with the exponent material are formed on the outer side surface of the segment body adjacent to each other, and a protection member having a segment joint formed to be connected to each other and connected to each other, To provide a precast concrete segment that can be used as a precast concrete segment.
According to still another aspect of the present invention, there is provided a method of manufacturing a precast concrete segment in which a plurality of blocks are disposed adjacent to each other to form an inner wall surface, the method comprising: molding synthetic resin into a mold to produce a tubular protective member And a step of securing the protective member to the inner surface of the segmented frame and casting and curing concrete inside the protective member of the segmented frame to produce a precast concrete segment. A method for manufacturing a cast concrete segment is provided.
A precast concrete segment and a method of manufacturing the same that can prevent breakage of the end portion according to the present invention provide the following effects.
First, it is possible to prevent breakage due to joining between the segments at the time of construction, detachment of end portions, and breakage, thereby improving the performance and reliability of the product.
Secondly, since the segment joint portion is formed integrally with the protective member, it is possible to omit the step of separately manufacturing and installing the steel joining apparatus (bolt box) for the existing inter-segment inter-segment joint portion, And it is possible to improve the economical efficiency.
Third, it is made of reinforcement-free reinforcement structure, so it has good corrosion resistance, unlike the conventional reinforcing steel and steel reinforcement structure, and can prevent the resistivity and the communication trouble due to reinforcing bars when the power source and communication port are applied.
Fourth, waterway, drainage, and wastewater tunnel are excellent in performance due to chemical erosion and excellent in salt water resistance.
Fifthly, since the place where the amount of sunlight is projected is small, the protection member formed of synthetic resin material (FRP) is very low in possibility of damage due to ultraviolet rays, so durability can be maintained.
