If the columnar hole is lowered and then raised, the internal earth and sand in the columnar hole and the soil hardening agent are well stirred and mixed. Therefore, after a certain period of time has elapsed, the soil in the columnar hole is hardened by the action of the soil hardening agent, resulting in the formation of two adjacent hard columns in the ground. After the traveling trolley 1 finishes excavating the left and right pairs of pillars and stirring and mixing the soil and soil hardening agent inside the pillars, it is moved by the pitch of the pair of pillars, and the same operation is repeated continuously thereafter. This forms a continuous vertical underground wall of pillars in the ground on both sides of the rail 1.

9, the pedestal elevating hydraulic cylinder device 33 is actuated to lower the cylinder pedestal 32, and in this state, when the liquid injection hydraulic cylinder device 34 lowers the liquid injection pipe 37, the liquid injection pipe 3 with a pointed tip is lowered.
7 penetrates into the ground below the road bed through a gap in the gravel of the road bed. After that, when pressurized soil hardening agent milk is supplied to the liquid injection pipe 37 via the supply pipe 38,
The milk permeates into the ground through the discharge hole 36.
Therefore, after a certain period of time has passed after the liquid injection pipe 37 is removed from the ground, the ground into which the soil hardening agent has permeated will harden. Installation interval of liquid injection pipe 37,
That is, it is preferable that the installation intervals of the liquid injection hydraulic cylinder devices 34 be determined so that the permeation ranges of the soil hardening agent milk by the respective liquid injection pipes 37 slightly overlap. Further, a relief valve is inserted into the hydraulic circuit of the hydraulic cylinder device 34, so that when a large insertion resistance is generated due to stones or the like, pressure oil is released and the descent of the liquid injection pipe is stopped. Note that when the above-mentioned work is performed by lowering the cylinder pedestal 32, the pedestal 32 and the fixed frame 31 are fixed with bolts 40, as shown in FIG. It is preferable that the upward reaction force of the device 34 is received by the fixed frame 31, that is, the entire traveling carriage 1.

Therefore, the same parts will be given the same reference numerals, and one will be explained with reference to FIG. A slider 51 is movably supported by the slider 50 . This slider 51 is configured to be moved manually or by a hydraulic cylinder device. A pivot seat 54 on which a swinging arm 52 is pivotally mounted via a pin 53 and a cylinder stand 56 supporting a hydraulic cylinder device 55 are fixed on the slider 51, and a piston rod 57 of the hydraulic cylinder device 55 is attached to the swinging arm. 52 by a pin 58, and the swing arm 52 can swing between a horizontal state (solid line in FIG. 5) and a vertical state (dashed line in FIG. 5) by means of a hydraulic cylinder device 55.

The rotating shaft 59 rotates by receiving the rotation of a hydraulic motor 63 mounted on the arm 52 through an endless chain 64.
A soil hardener milk supply pipe 66 is connected to the upper end of the soil hardener milk via a swivel joint 65. The pressurized milk supplied to the supply pipe 66 passes through the hollow rotary shaft 59 and the excavating stirring rod 62, and is discharged from a number of discharge holes 67 opened in the rod 62.

地盤中に横地中壁が形成されることとなる。 The horizontal underground wall construction machine 6 having the above configuration has a slider 51
Slide the pivot seat 54 onto the rail 2 as shown in Figure 5.
In this state, the hydraulic cylinder device 55 is operated by the hydraulic operation panel 68, and the swinging arm 52 is moved by the protrusion of the piston rod 57.
While gradually bending the hydraulic motor 63 downward,
When the excavation stirring rod 62 is rotationally driven, the ground on the lower surface of the rail 2 is excavated in an arc shape, and when the swing arm 52 finally reaches the vertical state, the excavation stirring rod 62 becomes horizontal, so that half of the lower surface of the rail 2 is excavated. Strong will be drilled. Therefore, for example, if the pressurized soil hardening agent milk is supplied to the supply pipe 66 while rotating the rocking arm 52 in a vertical state and the excavating stirring rod 62 penetrating the lower surface of the rail 2, the excavating stirring rod 62 Since the soil hardening agent milk discharged from the discharge hole 67 and the excavated earth and sand are stirred and mixed, a horizontal underground wall is formed in the ground under the rail 2 after a certain period of time.

横地中壁が形成できる。 The above is a case where a horizontal underground wall is formed on about half of the lower surface of the rail 2 using one of the horizontal underground wall construction machines 6, but if both construction machines 6 are used symmetrically, a continuous horizontal underground wall will be formed over the entire lower surface of the rail 1. If the above operations are performed continuously along the rail 2, a continuous horizontal underground wall can be formed.
上記地盤硬化機５および横地中壁構築機６は、

In principle, either one is selected and used depending on the ground conditions. An example of the selection criteria is
When the ground is relatively soft and the pressurized soil hardening agent milk easily permeates, the ground hardening machine 5 is used, and when the ground is hard, the horizontal underground wall construction machine 6 is used.

地中壁構築機６のいずれか一方でもよい。 This means that the present invention is realized by a combination of the vertical underground wall construction machine 4 and the soil hardening machine 5 or the horizontal underground wall construction machine 6. However, if these three devices are simultaneously mounted on the traveling trolley 1 as in the embodiment, there is an advantage that the soil hardening machine 5 and the horizontal underground wall construction machine 6 can be selectively used at the site.
However, either the vertical underground wall construction machine 4, the soil hardening machine 5, or the horizontal underground wall construction machine 6 may be used.
