摘要： PROBLEM TO BE SOLVED: To provide a construction method for a road which can be inexpensively constructed in a relatively short construction period, suppresses consolidation settlement caused by a dynamic load in the use of the road constructed on soft ground by filling, and prevents a step from being generated in a boundary between an upper part of an underground structure of the road and a part adjacent to the upper part in the use of the road crossing an area above the underground structure such as a covered conduit provided on the soft ground. SOLUTION: A plurality of columnar bodies 20, which are short enough to prevent an arrival at a bearing layer below the soft ground 11, are constructed in the soft ground 11 of a road foundation at an improvement rate of 10-50%, a net-like body 21 for reinforcement is laid on the columnar bodies 20; either or both of an additive material and an additive agent is or are further added to sediment and a solidifying material, and fixed for solidification, so that a shallow-layer improving soil layer 13 can be laid on the net-like body 21; and a road pavement 18 is constructed on the soil layer 13.

摘要： PROBLEM TO BE SOLVED: To suppress the consolidation settlement of a road by constructing multiple columnar bodies in the soft ground at the length not reaching a bearing stratum and at the improvement factor of a specific ratio, installing a reinforcing net-like body on the columnar bodies, and applying road pavement on the net-like body. SOLUTION: Multiple ground improving columnar bodies 20 are constructed in the object soft ground 11 of a road foundation by the machine stirring method at the length not reaching a bearing stratum below the soft ground 11 and at the improvement factor of 10-50%. A reinforcing net-like body 21 made of glass fibers is installed on the columnar bodies 20. A crusher run layer 18a, a graded grain crushed stone layer 18b, and asphalt concrete 18c are installed in sequence on the net-like body 21 to construct road pavement 18. A mixture of sediment and a solidifying agent or a mixture of the sediment and solidifying agent and an additive such as foam beads, rice hulls, a bubble generator, a clinker, and steel fibers may be installed on the columnar bodies 20 to form a shallow improved earth layer. The consolidation settlement of the road can be suppressed.

摘要： PURPOSE:To make improved soil affinitive to a lower layer and a side wall excellently by allowing improved soil to permeate in agrid and enhance a ground improvement effect by wrapping improved soil with a geotextile between the lower layer and an upper layer, in which original-position soil and a solidifying material are mixed and agitated. CONSTITUTION:A poor subsoil is excavated and a recessed section 2 is formed, the bottom ground of the recessed section 2 is agitated by a bucket mixing system, and cement 6and EPS beads 7 are mixed with original-position soil 5 and an improved-body lower layer 3 is formed. A geotextile sheet 4 is laid on the improved-body lower layer 3, and the side edge section of the sheet 4 is overhung to the outside of the recessed section 2. The excavated original-position soil 5, cement 6 as a solidifying material, the EPS beads 7 and water 8 are mixed by a mixer 9 and the inside of the recessed section 2, in which the sheet 4 is laid, is impregnated with improved soil 10. The peripheral section of the improved soil 10 is wrapped and fixed by the overhung geotextile sheet 4, and an improved-body upper layer is executed. Accordingly, the safety and workability are improved, a ground improving body resists banking and car load, and settlement and side flowing are prevented and the ground improving body can be constructed at a low cost.

摘要： PROBLEM TO BE SOLVED: To suppress settlement due to consolidation caused by dynamic load by specifying the height from the tips of soil-cement column bodies, constructed in the weak ground at a specified top view improvement ratio, to the road paved surface. SOLUTION: Soil-cement column bodies 1 are constructed in the weak ground of a road foundation at a top view improvement ratio of 20-60%, and a shallow improving soil layer 11 with cement group consolidating material mixed and consolidated is laid thereon. A grading-adjusted crushed stone layer 15 is further laid thereon and paved with asphalt-concrete 16. In this case, the height from the tips of the soil-cement column bodies 1 to the road paved surface is to be 4m or more. The plane layout of the soil-cement column bodies 1 is to be of grated shape, and it is desirable that the spacing of grating is not more than twice the height from the upper ends of the soil-cement column bodies 1 to the road paved surface. Settlement due to consolidation caused by dynamic load is thereby suppressed in spite of the small improved area of the deep layer ground, and a road can be constructed efficiently at a low construction cost.

摘要： A novel method to construct a reinforcing block in an embankment is provided, wherein a core rod to which a protrusion is molded on the tip, is preset inside a hollow rotating shaft with drilling and agitating blades affixed around its circumference, but with the protrusion on the core rod exposed at the front of the shaft. This drilling and agitating shaft rotates and bores into the earth while simultaneously mixing the soil so agitated with a fixing agent; then at a specified depth, the rotating shaft is withdrawn leaving the core rod to remain anchored in the soil while the fixing agent continues to discharge from the end of the hollow rod; and when the hollow rod is completely removed, a reinforcing block is intact within the soil and the tail end of the core rod exposed on the surface of the banking is directly or indirectly affixed to this surface. Alternatively a core rod with no protrusion can be inserted into the hollow rotating shaft which is first drilled into the embankment, such that the nose end of the said core rod is anchored into unagitated soil. In either case the reinforcing block so formed is comprised of an outer concentric tube of agitated soil mixed with a fixing agent molded around an inner concentric tube of reinforcing fixing agent molded around a core rod, and wherein the nose tip of the core penetrates into the unagitated soil beyond the end of the concentric reinforcing layers.

摘要： A method to construct a reinforcing block (3) in an embankment is provided, wherein a core rod (2) to which a protrusion is molded on the tip, is preset inside a hollow rotating shaft (13) with drilling and agitating blades (11,12) affixed around its circumference, but with the protrusion on the core rod (2) exposed at the front of the shaft. This drilling and agitating shaft (13) rotates and bores into the earth while simultaneously mixing the soil so agitated with a fixing agent; at a specified depth, the rotating shaft (13) is withdrawn leaving the core rod (2) to remain anchored in the soil while the fixing agent continues to discharge from the end of the hollow rod (13); when the hollow rod (13) is completely removed, a reinforcing block (3) is intact within the soil and the tail end of the core rod (2) exposed on the surface of the banking is directly or indirectly affixed to this surface.
