일반적으로 산업사회의 발전 및 토목기술의 발전으로 인하여 토지의 사용에 대한 효율성을 향상시키고, 비탈면을 타고 흘러내리는 빗물을 인위적으로 유도하여 배수시키기 위해 비탈면에 배수로 등의 시설물을 매설하고 있다.In general, due to the development of industrial society and the development of civil engineering technology, facilities such as drainage channels are buried on slopes to improve the efficiency of land use and to artificially guide and drain rainwater flowing down slopes.

그리고, 성토지의 연약한 비탈면을 보강하기 위해 잔디 또는 초지로 조성하거나, 육각, 사각형으로 조립되는 블록을 조성하여서 비탈면을 보강하여 주기도 한다.In addition, to reinforce the soft slope of the filly land may be made of grass or grass paper, or by forming a block assembled into a hexagon, a square to reinforce the slope.

그러나, 지구의 온난화상태로 인하여 생태기 변화에 따른 국지적인 집중호우가 간간히 발생하게 되는데, 이에 따라 쏟아지는 호우가 상기 지표에 침투하면서 절개지에 성토된 성토지를 스며들어 비탈면의 붕괴를 불러와서 막대한 피해가 발생하는 것이다.However, due to the global warming condition, localized heavy rains occur occasionally due to changes in the ecological period. As a result, the heavy rains penetrate the surface and infiltrate the land filled in the incision, causing the collapse of slopes and causing enormous damage. It happens.

절개지(69)에 성토된 성토지(64)에 의해 형성되는 비탈면(55)에 소정의 간격마다 배수관(52)을 다수열 매설하되, 상기 배수관(52)은 소정의 폭으로 바닥면(63)이 형성되고, 바닥면(63)의 양측으로 양측벽면(61)(62)이 돌출된다. 양측벽면(61)(62)의 외측으로는 각각 안전리브(71)(72)가 형성된다.A plurality of rows of drain pipes 52 are buried at predetermined intervals on the slope 55 formed by the land 64 formed at the cutout 69, and the drain pipe 52 has a predetermined width at the bottom surface 63. Are formed, and both side wall surfaces 61 and 62 protrude to both sides of the bottom surface 63. Safety ribs 71 and 72 are formed outside the side wall surfaces 61 and 62, respectively.

배수관(52)의 일측 안전리브(71)에는 상측 방향으로 돌출되는 유도대(70)가 결합된다.One side safety rib 71 of the drain pipe 52 is coupled to the guide bar 70 protruding upward.

배수관(52)과 배수관(52)의 사이 비탈면(55)에는 블록(80)을 결합하여 비탈면(55)으로 빗울이 침투하지 못하도록 덮어 주되, 블록(80)의 양측으로는 배수관(52)의 안전리브(71)(72)와 결합하기 위한 결합리브(77)(78)가 절곡 형성되며, 결합리브(77)(78)에는 고정구(81)가 형성되어 고정볼트(86)에 의해 배수관(52)과 결합된다.Block 80 is coupled to the inclined surface 55 between the drain pipe 52 and the drain pipe 52 so as to prevent rain from penetrating into the inclined surface 55, but the safety of the drain pipe 52 is provided on both sides of the block 80. Coupling ribs 77 and 78 for coupling with the ribs 71 and 72 are bent, and the coupling ribs 77 and 78 are formed with fasteners 81 to form a drain pipe 52 by fixing bolts 86. ) Is combined.

블록(80)에는 다수개의 식생구(79)와 식생조립구(75)가 형성되어 조경수 또는 초지 등을 식생하는 경우 뿌리가 비탈면(55)의 토사에 견고하게 식생되도록 지지하여 준다. 식생수의 식생에 의해 연약지반의 비탈면이 보강된다.In the block 80, a plurality of vegetation spheres 79 and vegetation assembly sphere 75 is formed to support the roots are planted firmly in the soil of the slope 55 when vegetation of landscape water or grassland. Vegetation of vegetation water reinforces the slope of soft ground.

상기 설명된 바와 같이 성토된 비탈면(55)에서 지표면에 흘러내려오는 빗물의 량이 너무 다량으로 내려오는 경우에도, 안전적으로 배수관(52)으로 빗물을 유도하여서 성토된 비탈면의 침하를 방지할 수 있다.As described above, even if the amount of rainwater flowing down to the ground surface from the sloped slope 55 is too large, it is possible to safely guide the rainwater to the drain pipe 52 to prevent settlement of the sloped slope.

본 발명은 절개지(69)에 성토된 성토지(64)로 형성되는 비탈면(55)에서 폭우 등으로 장마 등이 발생하는 경우, 절개지(69)에 인위적으로 성토지(64)를 성토하여 형성하는 비탈면(55)에 빗물이 침투하면서 지지력이 약해져 성토지(64)의 붕괴로 이어지는 것을 방지한다.According to the present invention, when rainy season occurs due to heavy rain or the like on the inclined surface 55 formed of the fillet 64 deposited on the cutout 69, the landfill 64 is artificially formed in the cutout 69. Rainwater penetrates the slope 55 to prevent the support force from weakening and leading to the collapse of the land 64.

본 발명은 블록(80)의 일측에 형성되는 식생조립구(75)에다, 조경수 등을 심어서 식생을 할 수 있도록 식생지지구(65)를 삽입 조립하며, 식생지지구(65)는 상측에 조립링크(66)가 구비되고, 측면에는 성토지(64)의 지지력 보강 및 블록(80)에 식생되는 초지 등의 뿌리의 착근력을 보강하기 위해 유통구(67)가 형성된다.
블록(80)에는 보조지지체(90)를 상측으로 돌출 형성하여 주고, 유통구(93)를 관통 형성한다.
따라서, 본 발명은 비탈면(55)의 경사지는 표면을 덮어주면서 보호하는 블록(80)에서, 장마 등으로 폭우와 동시에 토사, 간벌목, 자갈 등이 흘러내리는 경우, 배수관(52)을 막거나, 비탈면(55)의 하측방향으로 구축되는 도로, 경작지에토사가 범람하는 것을 방지할 수 있다.
한편, 본 발명은 성토지(64)에 폭우로 인한 빗물의 침투로 인하여 지지력이 약해지면서 발생하는 침하를 방지하기 위한 발명으로서, 블록(80)의 일측에 소정의 길이의 조립구(87)를 형성하여 준다.
그리고, 조립구(87)에는 성토지(64)의 침하 및 이동을 방지하여 주기 위해 지지벽체(82)를 삽입하여 조립하되, 상기 지지벽체(82)의 상측에는 걸림대(85)가 돌출 형성되고, 벽체에는 유통구(83)가 형성된다.In the present invention, the vegetation assembly (75) is formed on one side of the block 80, the vegetation support (65) is inserted and assembled so that the vegetation can be planted by planting landscape water, etc., the vegetation support (65) is on the upper side An assembly link 66 is provided, and a distribution port 67 is formed on the side to reinforce the bearing capacity of the land 64 and the reinforcement of roots such as grass paper that is vegetated in the block 80.
In the block 80, the auxiliary support 90 is formed to protrude upward, and a through hole 93 is formed therethrough.
Therefore, the present invention, in the block 80 to cover the inclined surface of the inclined surface 55 to protect the drain pipe 52 when the soil, thin lumber, gravel or the like flows at the same time as rainy weather, such as rainy season, or It is possible to prevent the earth and sand from overflowing into roads and farmland constructed in the downward direction of the slope 55.
On the other hand, the present invention is an invention for preventing the settlement caused by the weakening of the bearing capacity due to the infiltration of rainwater due to heavy rain in the land (64), an assembly (87) of a predetermined length on one side of the block (80) Form it.
In addition, in order to prevent settlement and movement of the land 64, the assembly port 87 is assembled by inserting the support wall 82, but the upper side of the support wall 82, the locking stand 85 is formed to protrude The distribution port 83 is formed in the wall.
