Abstract

In an LCD waste glass mixed precast concrete retaining wall, an eco-friendly precast concrete block has a texture like natural stone so that the appearance is excellent. The precast concrete retaining wall can be simply constructed by assembling blocks so that a construction period can be reduced by one fourth as compared to other construction methods. In addition, the concrete retaining wall places concrete by using LCD waste glass to have great economic feasibility and be eco-friendly.

Description

LCD 폐유리 혼입 프리캐스트 콘크리트 옹벽{LCD Waste Glass Precast Concrete Retaining Wall}LCD Waste Glass Precast Concrete Retaining Wall

건설 및 토목재료Construction and civil engineering materials

옹벽을 구축함에 있어서, 콘크리트 블록을 이용하는 다양한 형태의 종래 기술이 알려져 있다. 대한민국 등록실 용신안공보 제20-0412264호에는 옹벽을 축조하기 위한 블록과 이를 이용하여 축조된 옹벽의 일예가 개시되어 있다. 그런데 종래기술에서는 블록을 축조하여 옹벽을 구축하되, 블록만으로는 배면토사를 충분히 지탱하기 어려우므로 블록의 배면에 토목섬유들을 포설하여 배면토사에 토목섬유가 매설되도록 하여 배면토압을 지지하는 구성을 가지는 경우가 많다. 따라서 이러한 종래 기술에서는 옹벽 시공에 많은 비용이 소요되고 매우 번거로운 공정을 거쳐야만 하는 문제가 있다.특히, 종래의 블록을 이용한 옹벽의 경우, 모서리부분의 형성이 매우 어렵다는 한계가 있다. 즉, 옹벽에서 직각으로 꺾여서 돌출된 모서리부분을 형성하거나 오목하게 직각으로 꺾인 모서리부분을 형성하는 것이 종래기술 로는 매우 어려우며, 따라서 종래기술에 의해서는 다양한 선형의 옹벽을 구축하기가 어렵다는 한계가 있는 것이다.In constructing a retaining wall, various types of prior art using concrete blocks are known. Republic of Korea Registration Office Yongsinan Publication No. 20-0412264 discloses a block for building a retaining wall and an example of a retaining wall constructed using the same. However, in the prior art, a retaining wall is constructed by constructing a block, but since it is difficult to sufficiently support the back soil by using only the block, it has a configuration to support the back soil pressure by laying the geotextiles on the back of the block so that the earth fibers are buried in the back soil. There are many. Therefore, in the related art, there is a problem that a retaining wall construction is expensive and requires a very cumbersome process. Particularly, in the case of a retaining wall using a conventional block, there is a limitation that formation of corners is very difficult. That is, it is very difficult in the prior art to form a protruding corner part by bending at a right angle from the retaining wall or concavely bent at a right angle, and accordingly, there are limitations in that it is difficult to construct various linear retaining walls by the prior art. .

보편적인 철근콘크리트 옹벽은 공법으로 옹벽 종류는 중력식, L형, 역T형, 부벽식 등이 있고 배면의 토압을 지지하는 방식이다. 옹벽면의 토사가 충분히 다짐되지 않으면 물의 침투가 쉽고 별도의 배수구멍을 설치해야 하며 침투수 발생시 붕괴위험이 발생할 수 있다. 또한 옹벽체 시공과 뒷채움재 공사를 별도로 시행해야 하므로 공기 지연이 발생한다. 옹벽시공에 대한 비용이 상대적으로 크다.The common reinforced concrete retaining wall is a construction method. The types of retaining walls are gravity type, L type, reverse T type, butt type, etc., and support the earth's earth pressure. If the soil on the retaining wall is not compacted enough, water penetration is easy and a separate drainage hole must be installed, and the risk of collapse may occur in the event of infiltration. In addition, since the construction of the retaining wall and the construction of the backfilling material have to be performed separately, there is an air delay. The cost for retaining wall construction is relatively high.

블록식 보강토 옹벽으로 흙과의 결속력이 큰 보강재가 흙 속의 횡방향 변위를 구속함으로서 토체의 안정을 기하는 공법이다. 표면수 처리는 상부의 U형 풀륨관을 통해 옹벽체 밖으로 유도하며, 지하수 및 침투수는 기초 속채움 뒷채움잡석과 기초잡석내의 유공관으로 배수처리한다. LCD 폐유리르 활용하여 콘크리트의 재료를 대체한다.This is a block-type reinforced soil retaining wall, which is a method of stabilizing the soil by restraining lateral displacement in the soil by a reinforcing material having a large binding force with the soil. The surface water treatment is guided out of the retaining wall through the upper U-type pullium pipe, and the groundwater and infiltrate are drained to the backfilling basin and the perforated pipe in the foundation rubble. It uses LCD waste glass to replace the material of concrete.

성토는 대 회 95% 다짐을 시행, 보강토공법에서는 뒷채움재에 대한 다짐공정이 필연적으로 시공 완료 후 압밀 발생량이 상대적으로 적다. 블록설치와 뒷채움 토공작업의 병행 시공으로 옹벽공사와 뒷채움재 성토가 동시에 완료, 전면블록은 가용성이 적어 불균형한 외력에도 버틸 수 있다. 또한 공장 완제품으로 기초 저면에서 상부까지 동일작업의 반복으로 공기단축 효과, RC옹벽에 비해 40%이상 공기단축이 가능하다. 또한 LCD 폐유리를 활용하여 친환경재료일 뿐만 아니라 비용절감도 발생한다. The soil filling was performed 95% of the time, and in the reinforced earthwork method, the compaction process for the backfill material was inevitably relatively small after the completion of construction. With the installation of the block and the backfill earthwork, the retaining wall work and the backfill material fill are completed at the same time, and the front block has little availability and can withstand unbalanced external forces. In addition, it is possible to shorten the air by more than 40% compared to the RC retaining wall by repeating the same operation from the bottom to the top of the basic product. In addition, not only is it an eco-friendly material by using LCD waste glass, but it also reduces costs.
