도 8은 본 발명의 일 실시예에 따른 보강토 옹벽에서 보강조립구의 결속대 내부에 보조결속대를 삽입한 상태의 사시도이며, 도 9는 본 발명의 일 실시예에 따른 보강토 옹벽에서 보강조립구의 결속대를 수평연결대에 체결한 상태의 예시도이며, 도 10은 본 발명의 일 실시예에 따른 보강토 옹벽에서 보강조립구의 결속대에 저항판을 결합한 상태의 예시도이다. 8 is a perspective view of a state in which an auxiliary binding band is inserted into the binding band of the reinforcing assembly in the reinforcing soil retaining wall according to an embodiment of the present invention, Figure 9 is a binding of the reinforcing assembly in the retaining soil retaining wall according to an embodiment of the present invention 10 is an exemplary view illustrating a state in which a stand is fastened to a horizontal connecting rod, and FIG. 10 is an exemplary view illustrating a state in which a resistance plate is coupled to a binding band of a reinforcing assembly in a reinforcing soil retaining wall according to an embodiment of the present invention.

이를 보다 구체적으로 설명하면, 먼저 보조결속대(230a)(230b)를 수평연결대(130)의 외부를 감싸도록 위치시킨 후 제1,2결속대(210a)(210b)를 결합하거나, 제1,2결속대(210a)(210b)의 수평연결대삽입홈(211)에 보조결속대(230a)(230b)를 삽입한 상태에서 수평연결대(130)를 감싸도록 결합한다.In more detail, first, the auxiliary binding bands 230a and 230b are positioned to surround the outside of the horizontal connecting rod 130, and then the first and second binding bands 210a and 210b are coupled to each other. 2 is coupled to surround the horizontal connector 130 in a state in which the auxiliary binding band (230a, 230b) is inserted into the horizontal connecting groove insertion groove 211 of the (210a) (210b).

그리고, 결속대(210)의 저항판체결홈(212)에 저항판(220)의 체결대(222)가 서로 체결되도록 끼운다. 이때, 분할된 상태로 결합되는 제1,2결속대(210a)(210b)의 두께가 저항판(220)의 결속대삽입홈(221)보다 두꺼워지는 경우에도 탄성재질의 완충재(213)에 의해 체결이 용이해진다. 결속대(210)와 저항판(220)의 체결이 완료된 후에도 완충재(213)의 탄성에 의해 저항판(220)의 체결이 느슨해지는 것을 방지해 준다.Then, the fastening table 222 of the resistance plate 220 is inserted into the resistance plate fastening groove 212 of the binding table 210 to each other. At this time, even when the thickness of the first and second binding bands 210a and 210b coupled in the divided state becomes thicker than that of the binding band insertion grooves 221 of the resistance plate 220, the buffer member 213 is made of an elastic material. Fastening is easy. Even after the binding of the binding table 210 and the resistance plate 220 is completed, the fastening of the resistance plate 220 is prevented from being loosened by the elasticity of the shock absorbing material 213.

본 발명의 다른 실시예에 따른 보강조립구(200)를 수평연결대(130)에 조립하는 경우에는 제1,2결속대(210a)(210b)내부에 보조결속대(230a)(230b)를 삽입한 상태에서 수평연결대(130)와 밀착시킨다.In the case of assembling the reinforcing assembly 200 according to another embodiment of the present invention to the horizontal connecting rod 130, the secondary binding bands 230a and 230b are inserted into the first and second binding bands 210a and 210b. In one state it is in close contact with the horizontal connection 130.

그리고, 분할된 상태의 제1,2결속대(210a)(210b)를 체결부재(240)에 의해 견고히 체결한다. 제1,2결속대(210a)(210b)가 밀착 체결됨으로 인해 제1,2결속대(210a)(210b)에 구비되어 있는 저항판(220)도 밀착된다.Then, the first and second binding zones 210a and 210b in the divided state are firmly fastened by the fastening member 240. Since the first and second binding bands 210a and 210b are tightly fastened, the resistance plates 220 provided in the first and second binding bands 210a and 210b are also in close contact with each other.

전면블록(110)과 절개면(100) 사이에는 성토흙(140)이 성토되어 다짐 작업됨으로써 보강토 옹벽의 구축이 마무리된다. Filling soil 140 is filled between the front block 110 and the incision surface 100 is compacted to complete the construction of the retaining soil retaining wall.

한편, 전면블록(110)의 배면에 수평연결대(130)와 그리드(160)를 번갈아가며 설치하는 것도 가능하다.On the other hand, it is also possible to alternately install the horizontal connector 130 and the grid 160 on the back of the front block 110.

본 발명의 보강조립구(200)가 설치된 보강토 옹벽에 상부 압력이 가해지는 경우에도 저항판(220) 및 날개부(223)가 성토흙(140)의 횡방향 변위 발생을 차단하여 전면블록(110)이 전측으로 밀리는 것을 방지한다.Even when the upper pressure is applied to the reinforcing soil retaining wall in which the reinforcing assembly 200 of the present invention is installed, the resistance plate 220 and the wing 223 block the transverse displacement of the soil soil 140 so that the front block 110 ) Is pushed forward.

즉, 결속대(210) 내부에 삽입된 연질의 보조결속대(230)에 형성된 오목홈(231)과 돌출턱(232)이 수평연결대(130)의 돌출부분과 오목부분이 밀착되어 견고히 결합되어 있으므로, 저항판(220)이 성토흙(140)의 저항을 받는 경우에도 마찰계수가 커져 보강조립구(200)가 수평연결대(130)에서 밀리지 않게 된다.That is, the concave groove 231 and the projection jaw 232 formed in the soft auxiliary binding table 230 inserted into the binding table 210 are tightly coupled by the protrusion and the concave portion of the horizontal connector 130 are in close contact. Therefore, even when the resistance plate 220 is subjected to the resistance of the fill soil 140, the friction coefficient is increased so that the reinforcing assembly 200 is not pushed from the horizontal connection 130.

따라서, 본 발명의 보강토 옹벽은 성토흙(140)의 변위 발생이 차단됨으로써 전면블록(110)의 배부름현상이 발생하지 않게 되고, 안정적인 보강토 옹벽이 제공된다.Therefore, the reinforcement soil retaining wall of the present invention is prevented from generating displacement of the front block 110 by blocking the displacement of the fill soil 140, a stable reinforcement soil retaining wall is provided.

상기에서는 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해당 기술 분야의 숙련된 당업자는 하기의 특허 청구의 범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will 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 below I can understand that you can.
