The present invention relates to a sub-wall retaining wall using a high-strength plastic (FRP), to solve the problems of the existing concrete retaining wall has a high strength durability while reducing the retaining wall to reduce the construction and maintenance of the color expression, It relates to a subwall retaining wall using environmentally friendly high-strength plastic that can be freely harmonized with the surrounding environment.

Due to the increase of the back load due to the corrosion of the reinforcing steel due to the cracking of concrete occurring on the concrete retaining wall and the clogging of the drainage hole after installation, the retaining wall is damaged due to the sliding and the filling of the retaining wall, the assembly of the reinforcing bars and the concrete pouring and hardening Problems of human time and economics and mismatches with the surrounding environment due to concrete color

The present invention relates to a sub-wall retaining wall using a high-strength plastic (FRP), the corrosion of the reinforcing bars generated in the existing concrete retaining wall, the damage of the concrete retaining wall due to aging and the delay of time due to concrete hardening, dry shrinkage It eliminates cracks, maintenance and problems, and builds and transports sub-wall retaining walls using high-strength plastic in a male and female type block type to minimize the construction period by assembling equipment in the field. In preparation for the risk of earth pressure, the hollow part was made to increase the weight of concrete by placing the hollow part in the hollow part of the wall part of the subwall retaining wall using high strength plastic. In addition, in order to solve the increase in earth pressure generated from the back of the existing concrete retaining wall due to poor drainage, the hollow part is placed inside the subwall retaining wall using high-strength plastic, and it is used as a drainage passage for smooth drainage and at the same time. By reducing earth pressure, we make sub-wall retaining wall using structurally stable high-strength plastic. By using high-strength plastic, we can freely produce color, appearance and shape to provide sub-wall retaining wall using eco-friendly high-strength plastic of various colors and outstanding aesthetics. There is a purpose.

In order to achieve the object of the present invention as described above, the present invention,

In the subwall retaining wall using high strength plastic,

Subwall retaining wall using high-strength plastic made of double joint type resists the effects of flexural load due to earth pressure using high-strength plastic ribs and wing walls, and considers the problem of sliding by placing a comb-type resistance key on the bottom of the retaining wall. In addition, by installing drainage passages inside the subwall retaining wall using high-strength plastic, the incomplete drainage that may occur during rainfall can be solved to create a safer structure.The subwall retaining wall using high-strength plastic is more environmentally friendly with various colors. A subwall retaining wall using high strength plastic is provided.

The technical contents of the present invention will be described in detail with reference to the accompanying drawings. In the sub-wall retaining wall using high-strength plastic, as shown in the drawing, the sub-wall retaining wall using the high-strength plastic is formed in the male and female form of the sub-wall retaining wall (2) (4), and the sub-wall retaining wall using the high-strength plastic made of unit length is assembled. For this purpose, the structure is made in the form that can be overlapped as in (6), (8), (10) and (12), and the subwall retaining wall using high strength plastic made of each unit length is firmly using epoxy. It is possible to make a structure that can be integrated by bonding, and to prepare for the behavior due to the expansion and contraction of the structure, the joint part of the subwall retaining wall using high-strength plastic uses a thin rubber plate (28) to secure the structure. The side wall of the subwall retaining wall using high-strength plastic acting on the back side earth pressure is flexural failure against tension. By using a high strength plastic ribs 14 and nalgaebyeok 22 reinforcement to cope with tension to prevent it was to be a safer structure.

The wing wall 22 is placed on the rear part of the subwall retaining wall using high-strength plastic to increase the frictional force with the backfill soil on the back, thus securing the safety of sliding of the subwall retaining wall using the high-strength plastic. In order to increase, the comb-type resistance key 26 was placed to make the structure safer to slide, and the part using high-strength plastic to minimize the increase of the back side earth pressure caused by the rainfall or the incomplete drainage causing the sliding. The drainage passage 18 is provided inside the side wall of the wall retaining wall, and the drainage hole 20 is disposed on the side wall and the discharge port 24 is disposed on the outer side of the wall for smooth drainage. Safety in sliding by entering this drain passage and blocking the hole for drainage to prevent incomplete drainage In order to make this excellent structure, the concrete weight of reinforcement concrete frame (16) can be increased according to the site conditions, and the self-weight of the subwall retaining wall using high-strength plastic can be increased, so the situation may be dangerous. . In addition, by using high-strength plastic, it has the advantage of freedom of color and shape that can not be expected in concrete, so that it becomes a subwall retaining wall using environment-friendly high-strength plastic in harmony with the surrounding environment.

The present invention relates to a sub-wall retaining wall using a high-strength plastic as described above, by making the retaining wall into a high-strength plastic, the assembly structure is solid and drainage can be drained into the retaining wall. High-strength plastic is a durable material due to its high chemical resistance in areas where corrosion and salt degradation are expected due to its material properties, and it is possible to shorten air, unlike concrete retaining walls. As a result, the construction cost for the structure is reduced, so that color can be expressed economically and unobtained from the concrete retaining wall, thereby making it possible to create an eco-friendly prefabricated retaining soil retaining wall that can be harmonized with the surrounding environment.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims You will understand.
