Abstract

1. 발명이 속하는 기술분야1. Field of invention

토목이나 건축구조물의 기초공사를 행함에 있어서 물의 유입을 방지하거나 지반을 보강하기 위한 연약지반 개량방법에 관한 것임It relates to a method for improving soft ground to prevent the inflow of water or to reinforce the ground in the foundation work of civil engineering and building structures.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

주입재를 개량대상 지반에 주입하였을 때 주입재가 빠른 시간 내에 고화(固化)되도록하고, 주입재의 고화시간을 조절할 수 있도록하여 연약지반의 지질상태에 따라 효과적으로 지질을 개량할수 있도록 하는 것임When the injection material is injected into the ground to be improved, the injection material can be solidified in a short time and the solidification time of the injection material can be controlled to effectively improve the lipid according to the lipid state of the soft ground.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

물유리와 물을 혼합한 A액과 물과 시멘트의 첨가재를 혼합한 B액을 각각 분리된 상태로 개량 대상 지반에 주입하여 개량 대상 지반에서 A액과 B액이 혼합되면 빠른 시간내에 고화반응을 일으키도록한 것이며, A액과 B액을 이루는 각 성분량의 조절로 고화시간을 조절하는 것임A liquid mixed with water glass and water and B liquid mixed with additives of water and cement are injected into the ground to be separated separately, and when A and B liquid are mixed in the ground to be upgraded, a solidification reaction occurs quickly. It is to control the solidification time by controlling the amount of each component that forms A and B liquids.

4. 발명의 중요한 용도4. Important uses of the invention

연약지반의 지질상태에 따라서 효과적으로 지질을 개량할 때 사용됨Used to effectively improve lipids according to the geological condition of the soft ground

Description

연약지반 개량방법Soft ground improvement method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명을 실시하기 위하여 개량 대상지반으로 주입관을 설치하여 주입하는 설명도,1 is an explanatory diagram for installing and injecting an injection tube into the ground to be improved to carry out the present invention;

제2도는 (가)도는 순결재 사용시 고결시간을 나타내는 그래프로서는 B액 200ℓ중 시멘트가 50㎏. DAGS-1호가 25㎏, 물이 172ℓ일 때 고결시간의 변화를 나타내고는 B액 200ℓ중 시멘트가 75㎏. DAGS-1호가 25㎏ 물의 164.4ℓ일 때 고결시간의 변화를 나타내며는 B액 200ℓ중 시멘트가 100㎏, DAGS-1호가 25㎏ 물이 156.4ℓ일 때 고결시간의 변화를 나타내는 것임, (나)도는 완결재 사용시 고결시간을 나타내는 그래프로서는 B액 200ℓ중 시멘트가 50㎏, DAGS-2호가 25㎏. 물이 164.4ℓ일 때 고화시간의 변화를 나타내며는 B액 200ℓ중 시멘트가 75㎏. DAGS-2호가 25㎏. 물이 164.4ℓ일 때 고화시간의 변화를 나타내며는 B액 200ℓ중 시멘트가 100㎏ DAGS-2호가 25㎏. 물이 156.4ℓ일 때 고결시간의 변화를 나타내는 것으로 용시의 고결시간을 보여주는 것이다.2 is a graph showing the freezing time when using pure material (50). When DAGS-1 was 25 kg and water was 172 l, the freezing time was changed. 75 kg of cement was contained in 200 l of liquid B. DAGS-1 shows the change of freezing time when 164.4ℓ of 25kg water is 100kg of cement B solution, and DAGS-1 shows the change of freezing time when 156.4ℓ of 25kg water, (b) The graph showing the freezing time when using the finished material is 50 kg of cement and 25 kg of DAGS-2 in 200 l of liquid B. When the water is 164.4ℓ, it shows the change of solidification time.It is 75㎏ of cement in 200ℓ of liquid B. DAGS-2 No. 25 kg. The change in the solidification time when water was 164.4ℓ was 25kg of 100kg DAGS-2 in cement of 200ℓ of liquid B. When water is 156.4ℓ, it shows the change of freezing time.
