摘要： A boring-injection device comprises a fluid supplying hollow rod, a fluid discharge portion at the lower end of the rod, and a packer element inflatable from the rod to seal a space between the rod and a borehole wall at a desired depth position. The rod is surrounded by a sheath so that the packer element and fluid discharge portion can be protruded out of and retracted within the sheath in a body. They are retracted during the boring operation and protruded during injecting or investigating operation. The device can be used for practising a method of ground improvement or a method of ground investigation.

摘要： A method for improving the ground or foundation by injecting a grouting agent from the tip end of a hollow injection rod inserted into a boring hole formed in the ground at site so as to infiltrate it into the ground to be solidified. The injection is carried out by varying an injection pressure or injection rate depending on the intensity, particularly, the tensile strength, of the ground so that no vein-like coagulation can be formed around the injection rod, and a columnar or spherical coagulation can be formed.
摘要翻译：一种用于通过从插入到现场的地面中形成的钻孔中的中空注射杆的尖端注入注浆剂以将其渗透到地面中以固化来改进地面或基础的方法。注射通过根据强度，特别是地面的拉伸强度改变注射压力或注射速率来进行，使得在注射杆周围不会形成静脉状凝结，并且柱状或球形凝结可以是形成。
