Abstract
Description
(1) 土壌に穴を開け、その部分の土壌を地表に導き出すことにより、単位面積当りの土壌密度を低下させる
(2) 土壌に穿った穴に土壌改良資材を充填することができ、そのことにより長期間にわたり土壌改良の効果を持続させ得る
(3) 噴出する圧縮空気が土壌に触れることにより、掘削部土壌表面の間隙を増やし、吸水性・通気性を高める
(4) 作業中の圧縮空気が土壌中に浸透するため、土壌中の根に酸素の供給をし易くする
などの効果を奏するものの、この文献記載の空気式土砂処理装置を用いての作業には、常時7~8気圧の圧縮空気を送り続けることとなり、また必要とされる圧縮空気総量が最終的に多くなるため、例えば重量が1トン前後といった大型コンプレッサーを用いる必要があり、庭木や街路樹などの樹木の手入れなどでは、作業性に欠け、コンプレッサーの運搬も容易ではない。また、土の排出能力が高く、作業員への土の跳ね返りもひどいので、作業が進め難く、作業後には全身が返り土で汚れてしまうといった問題もある。 By soil improvement treatment using such pneumatic soil treatment equipment,
(1) Decrease the soil density per unit area by making a hole in the soil and deriving that part of the soil to the ground surface. (2) The soil improvement material can be filled in the hole drilled in the soil. The effect of soil improvement can be maintained for a long period of time by (3) The compressed air that is blown out touches the soil to increase the gap on the soil surface of the excavated part and increase the water absorption and breathability. (4) Compressed air during work Is effective for supplying oxygen to the roots of the soil, but the work using the pneumatic soil treatment device described in this document is always 7-8 atm. Since compressed air will continue to be sent and the total amount of compressed air required will eventually increase, it will be necessary to use a large compressor with a weight of around 1 ton, for example, in the care of trees such as garden trees and street trees ,Workability It is not easy to transport the compressor. Moreover, since the soil discharging ability is high and the rebounding of soil to the worker is severe, there is a problem that the work is difficult to proceed and the whole body returns and gets dirty with the soil after the work.
