Outline of the
construction
method		 ㆍIt is an effective technique for preven -ting full filling and ground deformation of the poured adobe by injecting low- pressure into the foamed cement slurry of high-magneticity. ㆍA method of filling old pipes with pump cars, using cement mallet (1:1~1:3) ㆍA method of filling old pipes with pneumatic injection, using sand ㆍA technique to fill an old tube using urethane drug with two- component foam infusion material
infusion material ㆍCement+water + aerosol + (mixture)
ㆍspecific gravity : 0.5 ~0.6		 ㆍCement+Sand+Water
ㆍweight : 2.3 		ㆍCement+Sand+Water
ㆍweight : 2.3 		ㆍUrethane solution:TBU(A)+CBU(B)
ㆍspecific gravity: not more than 0.1
Advantage ㆍThe process is simple and construction is fast.
ㆍExcavation is not necessary (or minim -ized)
No risk of breakage and disposal costs.
ㆍIt has the best fluidity and long-distance injection (About 800M) is possible,
Can be minimized for branch offices.
ㆍLight weight (0.5 ~ 0.6) low pressure injection
(2 ~ 5kg / ㎠) affect the ground
around the pipe Not allowed.
ㆍExcellent insulation and vibration absor -ption effect.		 ㆍSimple process and fast construction.
ㆍHighest strength.		 ㆍExcellent insulation and vibration absorption effect. ㆍExcellent insulation and vibration absorption effect.
ㆍLightest weight
Weight 45kg/㎡ 100kg/㎡ 66kg/㎡ 120kg/㎡
Weakness ㆍThe existing closed pipe Removal costs are incurred when installing underground facilities. ㆍIt has more fluidity than light -weight bubble Con'c One injection distance is short.(Within 100M)
→ injection station / installation point of injection tube The con -struction cost is increased.
ㆍAs the injection distance (injection amount) increases Separation phenomenon of material (sand) As a result, It is difficult to secure full filling.		 ㆍFrom pneumatic injection At distances of up to 10 meters There are restrictions on injection.
→ short injection distance, homogeneous filling Difficult
→ Increase of installation point of injection base
ㆍThe injection amount of 20m3 / 8hr or less, Air increases unrealistically.
→ Apply to large doses difficulty.		 ㆍFoaming and hardening speed is fast Very short injectable distance (Within 30M).
→ The injection distance is short, Increase in installation area
ㆍMaterial cost is the most expensive.
→ except for urgent small sections Practically difficult to apply.
ㆍIt is weak in water and moisture. Due to its high fluidity, Not suitable.
Applicability ㆍTraffic is crowded, Excellent applicability to urban areas.
ㆍSection where drilling equipment is difficult to access.
ㆍConcerned about subsidence due to closed Areas requiring urgent action.		 ㆍTraffic is congested, Applicable to many urban areas.

Economics ㆍSchematic construction cost : about 220,000 won/m (design, direct construction cost)
※The incidental cost savings, such as shortening of air, handling of ground materials, and processing of civil complaints, are also very large		 ㆍSchematic construction cost: approx. 150,000 won/m (design, direct construction cost) ㆍSchematic construction cost : approximately 340,000 won/m (design, direct construction cost) ㆍSchematic construction cost : approximately 2 million won/m (design, direct construction cost)
