본 발명은 정착구를 이용한 부벽식 옹벽 시공방법에 관한 것으로 보다 상세하게는 옹벽벽체에 설치된 다수의 정착구가 옹벽저판에 삽입되어 확장날개가 확장된 상태에서 그라우트를 주입하여 보다 견고하게 옹벽벽체를 지지하므로 하중 저항이 종래보다 더욱 강화된 것이다.The present invention relates to a method of constructing a buttress-type retaining wall using anchors. More specifically, a plurality of anchors installed on the retaining wall are inserted into the retaining wall bottom plate and grout is injected with the expansion wings expanded to support the retaining wall more firmly. Load resistance is further strengthened than before.

일반적으로 옹벽은 자연적으로 형성된 경사면이나 도로공사, 철도, 택지개발등으로 인한 인위적인 경사면의 지지기반을 확보하거나, 구조물을 지지하고 있는 토압이 연약하여 구조물의 파괴 우려가 있는 경우 또는 부등침하가 예상되는 경우에 실시하는 지지기반 확보를 위한 구조체이다.In general, retaining walls are used to secure the support base for naturally formed slopes or artificial slopes caused by road construction, railroads, housing development, etc., or when the earth pressure supporting the structure is weak and there is a risk of destruction of the structure, or when differential settlement is expected. It is a structure to secure a support base in case of emergency.

종래의 옹벽은 일례로, 첨부된 도면 도 1에서 보는 바와 같이, 지면에 대해 수직으로 세워진 벽체(10), 벽체(10)의 일면을 지지하도록 세워진 보벽체(20), 지반에 매설되면서 벽체(10)와 보벽체(20)의 하부가 고정되는 바닥체(30)를 포함하여 이루어진다.As an example, as shown in Figure 1 of the attached drawing, a conventional retaining wall includes a wall 10 erected perpendicular to the ground, a reinforcement wall 20 erected to support one side of the wall 10, and a wall (20) buried in the ground. 10) and a floor body 30 to which the lower part of the reinforcement wall body 20 is fixed.

여기서, 벽체(10)와 바닥체(30)의 고정은 바닥체(30)에 가공된 벽체삽입홈(31)에 벽체(10)의 하단 부위가 삽입되어 이루어질 수 있다.Here, the wall 10 and the floor 30 can be fixed by inserting the lower part of the wall 10 into the wall insertion groove 31 machined in the floor 30.

그리고 보벽체(20)와 바닥체(30)의 고정은 바닥체(30)의 상부에 배치되는 삽입고정몸체(32)에 보벽체(20)의 하단면으로부터 돌출된 고정돌출체(21)가 삽입 고정되어 이루어질 수 있다.In addition, the securing wall 20 and the floor 30 are fixed by inserting and fixing the body 32 disposed on the upper part of the floor 30 with a fixing protrusion 21 protruding from the lower surface of the strengthening wall 20. It may be inserted and fixed.

하지만, 삽입고정몸체(32)가 수용되도록 바닥체(30)에 가공된 고정체안치홈(33)에 매입되는 정착봉의 돌기 및매입 깊이가 얕으므로 삽입고정몸체(32)와 바닥체(30) 간의 고정력이 약할 수 밖에 없는 구조적인 문제점이 있었다.However, since the projection and embedding depth of the fixing rod embedded in the fixture resting groove 33 machined in the bottom body 30 to accommodate the insertion and fixation body 32 are shallow, the insertion fixation body 32 and the bottom body 30 There was a structural problem where the fixation between the liver was inevitably weak.

상기와 같은 문제점을 개선하기 위하여 본인의 특허등록 제10-2127192호인 '하중 저항력이 강화된 부벽형 옹벽 및 이의 제작방법'이 개시되어 있다.In order to improve the above problems, the author's Patent Registration No. 10-2127192, 'Buttress-type retaining wall with enhanced load resistance and method of manufacturing same', is disclosed.

상기 등록특허는 첨부된 도면 도 2에서 보는 바와 같이 벽체(100), 벽체(100)의 일면을 지지하도록 세워진 보벽체(200), 벽체(100)와 보벽체(200)를 고정하기 위해 지반에 매설되는 바닥체(300)와, 보벽체(200)와 바닥체(300)를 결합시키는 체결수단(400)을 포함하여 이루어진다.As shown in the attached drawing FIG. 2, the registered patent covers a wall 100, a reinforced wall 200 erected to support one side of the wall 100, and a reinforced wall 200 on the ground to fix the wall 100 and the reinforced wall 200. It includes a buried floor body 300 and a fastening means 400 that couples the reinforcement wall body 200 and the floor body 300.

상기 체결수단(400)은 보벽체(200)의 하부와 바닥체(300)의 상부를 체결하는부재이며, 지지판(410)과 체결구(420)로 이루어져 있다.The fastening means 400 is a member that fastens the lower part of the reinforcement wall 200 and the upper part of the floor body 300, and is composed of a support plate 410 and a fastener 420.

그러나, 상기 등록특허는 보벽체(200)를 견고하게 지지하지 못하는 문제점이 있었다.However, the registered patent had a problem in that it could not firmly support the reinforcement wall 200.
