It is an object to provide a sandbag which can form a permanent construction with which it does not need to be removed after construction.

必要でないことはいうまでもない。[Means for Solving the Problems and Actions] The sandbag for civil works according to the present invention comprises (A) 100 parts by weight of soil and (B) (a) 100 parts by weight of portland cement, and (b) slaked lime and silica fine powder. At least one of 10 to 70 parts magnesium chloride, calcium chloride, at least one of soda ash 10 to 30 parts montmorillonite 3 to 20 parts zirconia 3 to 20 parts and sodium lignin sulfonate, potassium lignin sulfonate, tripoly A curing composition (b) containing 1 to 5 parts by weight of at least one of sodium phosphate and potassium tripolyphosphate (provided that the total of,, and is 100 parts by weight) And 5 to 20 parts by weight of a soil hardening agent, which is filled in a bag that is permeable to water but impermeable to soil.
When water penetrates into the soil of the present invention, the soil hardener mixed with the soil reacts with the water and hardens, resulting in the high compressive strength required for a permanent construction. Therefore, when this sandbag is piled up for construction, it is necessary to sprinkle water while stacking or to spray water after stacking to make the sandbag contain water. It is needless to say that such watering is not required when the sandbag is put into water or when the work is performed during rainfall.

の強度が低下する。In the present invention, the hardening composition (b) in the soil hardener (B) to be mixed with soil has the above-mentioned composition. Of this composition, slaked lime and silica fine powder participate in the development of long-term strength based on the so-called pozzolanic reaction. Loses balance and decreases strength. Magnesium chloride is a fast-strengthening agent that recovers the delay in solidification time due to the incorporation of a dispersant such as ligninsulfonate.
If it is less than 0%, the effect is weak, and if it exceeds 30%, the balance with other components is lost, resulting in lack of long-term strength and rapid weathering. Although montmorillonite is extremely useful for reducing the water absorption of a cured product and improving weatherability, zirconia is particularly effective in increasing the uniaxial compressive strength and bending strength of a cured product and producing a tough block. ,
If the content is less than 3% of the total amount of the composition, the expected effects cannot be obtained. If the content is more than 20%, the balance with other components is lost as described above, resulting in a lack of long-term strength. Is particularly indispensable for the blending of montmorillonite and zirconia, but if it is less than 5% of the total amount of the composition, the contribution to the dispersion of particles of other compositions is insufficient.
If it exceeds 60%, the balance with other components is lost, and the strength of the cured product decreases.

０ｋｇｆ／ｃｍ２以上にする必要があるからである。[0007] The mixing ratio of the soil (A) and the soil hardening agent (B) is determined by the hardening of the hardening agent or the portland cement.
It is desirable that the compressive strength of the mixed soil be about 20 kgf / cm 2 . The permeability coefficient of the mixed soil is 10 −6 to −7 cm / s
In general, a uniaxial compressive strength of 2

When the sandbags are piled up, a gap is formed between the sandbags, and a water blocking wall cannot be formed. Therefore, the weight is preferably 60 to 90% by weight, more preferably 70% by weight based on the bag.

な箇所を修繕する等、二度手間となることが多い。Although there are various methods for slope protection work, it is necessary to reinforce the slope protection wall when the ground is soft or easily collapsed. In this case, for example, if an attempt is made to form a slope with soil mixed with concrete or a hardening agent, a formwork is provided inside the excavated slope and the ready-mixed concrete is poured between the ground and the formwork. Then, the soil will be launched while compacting the soil mixed with soil and hardener. The construction of this formwork is extremely time-consuming work, and when the formwork is completed and completed, it is often troublesome to find a leaked portion or repair a defective portion.

It has the feature that it can definitely build a slope even in the recent lack of skilled workers. If there is a risk of water leakage, fill the joints with soil mixed with a solidifying agent.

In the above, 2 'indicates a joint. As mentioned above, it is preferable to spray water while stacking the sandbags and to firmly compact the sandbags.

It can be either raised and hammered into the water barrier or concrete poured into the water. If the sandbag of the present invention is put into the excavated trench, tamped and consolidated, the water blocking wall can be easily formed.

A trench is excavated to a depth that can be excavated with a yumbo or the like, and the sandbag of the present invention is put into the trench and compacted (first sandbag). If the target depth cannot be reached by a single excavation, the soil is removed while pumping up to the second water level indicated by 9 in FIG. 3, and a trench is excavated therefrom, and the sandbag is inserted and tightened. Harden (second sandbag). When the target depth is reached, the soil inside is removed while pumping, and the sandbags of the bottom slab are laid to complete the outer wall of the storage. If a finished surface layer is applied as a blind on the inside, a storage room can be easily provided underwater.

After flooding, the sandbags often do not have sufficient strength as a dike, so they must be removed to build a dike. If this sandbag is the sandbag of the present invention, the sandbag will have sufficient strength over time, so if this is used as the core of the embankment and a regular embankment is built on it, The embankment will be stronger than the existing embankment, and the emergency work will be utilized as it is, which will be economical and help save labor.

In this case as well, when the water content of the soil is reduced and the restoration work is performed, the strength of the input sandbag is insufficient, and the slope is restored separately. If
If the sandbags of the present invention could be used for first aid,
Since the slope can be restored using the sandbags, the restoration can be carried out at an early stage, thereby increasing safety and reducing costs.
