A horizontal member; And an upper roof structure formed on both side portions of the horizontal member and formed of a guiding member for preventing the water from falling on the road or the rail by flowing earth and rock. The present invention relates to a hybrid slope collapse safety structure having a function of a cancerous tunnel.

In Korea, more than 70% of the country's land is mountainous, so when large-scale land construction, road construction or railway construction is inevitably formed cut slopes, the number and size is also increasing. Therefore, securing safety in the design and construction of cut slopes is a basic requirement for safe and smooth use of structures such as constructed land or newly established roads and railways. In particular, in recent years, the slopes of natural slopes or artificial slopes have to be urgently constructed in terms of environmental protection or construction cost reduction. Therefore, the risk of slope safety due to natural disasters will be greater. In particular, it is required to secure the safety of these cut slopes in the guerrilla heavy rain in summer, typhoon or spring soil or rock slope in Korea, and if the cut slope loses its safety, it collapses. In this case, it can lead to the loss of railroads and roads, the loss of traffic, the destruction of houses, buildings, etc., as well as the loss of property, as well as the loss of life. will be.

Disaster prevention measures against the collapse of steep slopes require various regulations to be established by setting standards for the design, construction, and maintenance of slopes, but there is still a problem in Korea that there is not enough consideration for them. In the case of cut slopes, measures commonly used in Korea to secure safety are largely divided into protection method (safety rate maintenance method) and reinforcement method (safety rate increase method) according to the safety rate and function of the slope itself. Here, the protection method is divided into rockfall protection net, rockfall prevention fence, rockfall prevention retaining wall and rock tunnel.

The type of protection tunnel, which is one of these protection methods, is relatively small in Korea, and it is mostly designed and constructed as a concrete structure. 1A and 1B show cross-sectional views of a conventional reinforced concrete armed tunnel and a corrugated steel armed tunnel, respectively. As shown in the figure, the conventional arm tunnel has a considerable amount of coverings 30 and 30 'from the slopes 20 and 20' from the slopes 20 and 20 'onto the arm tunnels 10 and 10'. However, if the cover is installed with a gradient of more than 1: 1.5 above such conventional tunnels, the soil pressure on the tunnels will increase considerably, making the tunnels very structurally unstable and possibly collapsed. There is a problem in that the soil can not be stacked with a gradient of 1: 1.5 or more. In order to solve the problems of the conventional armed tunnels against such increased earth pressure, a method of raising the cross section of the used member and increasing the amount of used rebar is proposed, but this method only complicates construction. But there is a problem of increasing the construction cost.

In order to solve some of the problems of the conventional Fiamese tunnel, Utility Model Registration No. 20-245924 filed as Utility Model No. 2001.5.10. Discloses an installation structure of a rockfall prevention tunnel. As shown in FIG. 2, the rockfall prevention tunnel installation structure according to the above technique has a fan-shaped corrugated steel sheet structure in which a plurality of corrugated steel sheets are assembled by bolting between an edge portion of a road and a rocky surface in a tunnel shape that surrounds the road. Constructed, the concrete foundation portion (3) is installed at the upper and lower end of the corrugated steel sheet structure, characterized in that the soil fill layer (2) is formed on the top of the corrugated steel sheet structure (1) to pile the soil in a circular form do.

However, the structure according to the conventional registration utility model is difficult to install on a wide road due to its structural characteristics, there is a problem that the soil fill layer to be stacked on the structure can not be stacked to the desired thickness. Furthermore, if the slope collapses during heavy rain or heavy rain, soil or rock load acts on the soil fill layer of the structure, and the structure may be collapsed due to excessive load.

The present invention was created to solve the problems of the conventional arm tunnel, the first pillar member which is continuously installed along the slope located at one edge of the road, and is provided at regular intervals along the other edge of the road A reinforced concrete or corrugated lower body structure comprising a second pillar member and a slab member which is connected in a transverse direction to the first pillar member and the second pillar member in a longitudinal direction of the armed tunnel; And a plurality of first vertical column members formed at regular intervals on the first pillar member of the reinforced concrete or corrugated steel lower body structure and formed at regular intervals on the second pillar member of the lower body structure. A vertical member composed of a plurality of second vertical pillar members formed shorter than the vertical pillar members; It is installed on the first and second vertical pillar members formed at regular intervals and connected from the first longitudinal member and the inclined first longitudinal member extending across the road or railway width to the opposite safety zone. A horizontal member comprising an inclined second longitudinal member fastened to a slope having a predetermined slope and a cover plate installed on the inclined first and second longitudinal members and receiving and sliding soil and rock; (horizontal member); And an upper roof structure formed on both side portions of the horizontal member and formed of a guiding member for preventing the water from falling on the road or the rail by flowing earth and rock. By providing a hybrid type of slope collapse structure that has the function of the arm, the one-side backfill of the arm can be made only to the lower body structure. Its purpose is to make it easy and safe to install the Fiam tunnel while reducing construction costs by reducing the amount of steel used.

The present invention is a patent application No. 10-0790759 filed by the applicant of September 21, 2006 and patented on September 21, 2007 "improved slope collapse safety structure having one side opening with the function of the arm cancer tunnel" As an invention, it is possible to install in existing type of existing rock tunnels in any type of new or already constructed, so that the safety zone on the opposite side of the slope can be safely and simply dropped on the road or railway without dropping large amounts of soil or rock flowing from the slope at low cost.
