Abstract

PURPOSE: A soil solidification stabilizer is provided, which solidifies and stabilizes the soil to obtain the porous soil having excellent water permeability and air ventilation by generating ettringite through the hydration with the water contained in the soil. CONSTITUTION: The soil solidification stabilizer comprises 55-65 wt% of fly ash (CaO); 20-30 wt% of gypsum (SiO2); 5-10 wt% of aluminum sulfate; and 1-5 wt% of potassium carbonate.

Description

지반고화안정제{Soil Stabilizer}Soil Stabilizer

종래 공법에서 사용되는 시멘트 · 석회계 무기질 재료는 대체로 건조경화반응형 지반고화제로서 지반이 안정화되는 시간이 길어 시공후 3∼4일 정도의 양생기간이 필요하여 양생기간 내에 강우가 내릴 경우 지반이 유실될 우려가 있으며 형성되는 지표면이 불안정하여 표면의 균열과 홈이 많이 발생하여 만족할 만한 결과를 얻지 못하였다.The cement-lime mineral materials used in the conventional method are dry curing reaction type ground hardeners, which require a curing period of about 3 to 4 days after construction because of the long time to stabilize the ground. In addition, the surface formed is unstable, so many cracks and grooves on the surface did not produce satisfactory results.

또한 토질이 강알칼리성으로 되며 알칼리 장해는 시간이 흐르면서 물이나 토양에 녹아들어 점차적으로 식물 생육 및 토양에 좋지않은 영향을 미친다.In addition, the soil becomes strongly alkaline, and alkali disturbance dissolves in water or soil over time, and gradually adversely affects plant growth and soil.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서 토양의 수분과 수화반응하여 토양을 내수성 단립화 시킴으로서 시공후 단시간(2∼3시간)내에 지반을 고화안정화시키어 다공질이며 보수성과 통기성이 우수한 중성역의 지반고화안정을 형성함에 있다.The present invention is to solve the above problems by hydration reaction with the moisture of the soil to make the soil water-resistant granules to stabilize the soil within a short time (2 to 3 hours) after construction, porous, water-retaining and breathable neutral zone It is in forming ground stability.

이하 본 발명의 무기질 재료는 주성분이 CaO 60%+SiO225%+Al2O38%+Fe2O32%+기타 성분이 5% 정도로 구성된 미세 분말로서 수분과 반응하여 경화반응 생성물인 에트린카이트(ETTRINGITE)를 생성시키고 포조란(POZZOLAN) 반응촉진과 함께 토양입자를 그물망과 같이 결합형성하여 무수한 다공질 성상을 만들며 입자간 공극을 충전하며 그 자체의 경도와 강도를 유지케한다. 또한 토양중의 수분을 흡수하고있고 통기성과 보수성이 우수하며 토질의 PH 조절치가 중성역으로 유지되어 환경보존에도 기여한다.Hereinafter, the inorganic material of the present invention is a fine powder composed of CaO 60% + SiO 2 25% + Al 2 O 3 8% + Fe 2 O 3 2% + other components as about 5%, and reacts with moisture to produce a curing reaction product. It produces Ettringite and promotes the reaction of POZZOLAN, and forms soil particles in the form of a mesh to form a myriad of porous properties, fills pores between particles, and maintains its own hardness and strength. In addition, it absorbs moisture from the soil, has excellent breathability and water retention, and contributes to the preservation of the environment by maintaining the pH of the soil in the neutral zone.

[실시 예1]Example 1

강우로 인해 불량해진 공원의 조깅용 보도 원토(일반 마사토) 약 10㎥과 본 발명의 무기재료 300kg을 굴삭기를 이용 교반한 후 돌과를 사용하여 전압하여 보도를 조성하였다. 시공 약 3시간 후 수압 실험을 한 결과 단시간내에 수화반응에 의한 단립화가 진행되어 고화 안정화되었으므로 세굴이나 표토의 수니화 현상이 나타나지 않았으며 조깅에 적당한 강도와 탄성을 유지하고 있음을 발견하였다.The jogging sidewalk raw material (general Masato) of about 10m3 and 300kg of inorganic material of the present invention were stirred with an excavator and then voltaged using a stone wall to make a walkway due to rainfall. As a result of the hydraulic test about 3 hours after construction, the solidification was stabilized by the hydration reaction in a short time, so it was found that the scour or topsoil did not appear and the jogging and topsoil were maintained.

[실시 예2]Example 2

강우시 표토의 질척거림과 함몰로인해 차량통행에 지장을 초래하는 토목공사장의 차량진입로 불량원토 약 20㎥과 본 발명의 무기재료 500kg을 실시 예1과 같이 교반 전압하여 진입로를 조성하였다. 시공 약5일 후 폭우가 쏟아졌으나 고화안정된진입로는 덤프트럭 등 중장비의 통행에 아무런 문제가 없었다.The entrance road was formed by stirring voltage of about 20m 3 of poor raw soil and 500kg of inorganic material of the present invention as a vehicle entry of a civil engineering work site, which causes obstacles to vehicle traffic due to scouring and depression of the topsoil during rainfall. After about 5 days of construction, heavy rains poured out, but there was no problem with the passage of heavy equipment such as dump trucks.
