Description

[Detailed explanation of the invention] The conventional cement milk injection and stirring method takes 3 to 4 days to harden, and the stirring is performed using an impeller installed on a vertical shaft, which causes deformation of hardened columns due to mud pressure, prolongation of construction time, and damage to boards. There were defects that caused phenomena such as water swelling and made it difficult to improve work efficiency. In addition, it is difficult to perform reciprocating stirring action from the bank in the river width direction using a long arm and long boom to stir the mud bottom across the width of the river between both banks, and where plants such as reeds grow on the mud bottom. There was a problem in that stems, leaves, roots, etc. became obstacles to stirring, making stirring difficult.

In order to solve the above-mentioned problems, this project aims to
A horizontal rotating shaft 2 is provided at the tip of the horizontal rotating shaft 2, a plurality of portal frames 3 are provided on the same shaft 2, and a stirring plate is provided at the tip of the portal frame 3 in a direction parallel to the rotating shaft 2 and intersecting with the rotating direction. 4 are provided in the diameter direction of the rotating shaft 2, and the agitator 4 is provided with large and small cutting claws 22, 23 protruding outward, and the base end of the machine frame 1 is connected to the arm 6 of the backhoe 5. The operating arm 1 provided at the tip and the arm 6
The soft ground agitator is formed so that it can be pivotally attached to the tip of the soil agitator 7 by means of pins 7 and 8, respectively.

A reduction sprocket 9 is provided at one end of the horizontal rotating shaft 2, and a drive chain 13 is wound between it and a drive sprocket 12 provided on an output shaft 11 of a hydraulic motor 10 provided at the base end of the machine frame 1. The portal frame 3 has radial arms 14, 14 provided at both ends of the rotation shaft 2.
Connect the tip of the coaxial 2 with a parallel rod 15,
The stirring plate 4 is provided on the inner surface of the continuous rod 15, and the longitudinal section T
Four of them are provided on the shaft 2.
The connecting rod 15 is provided in the direction of rotation, and the stirring plate 4 is provided to intersect at right angles to the direction of rotation. Above machine frame 1
A shaft support plate 16 is provided protruding from the base end of the arm 6, and pins 7 and 8 are fitted into two through holes drilled in the plate 16, respectively, and one pin 7 is drilled at the tip of the arm 6. By fitting the other pin 8 into the through hole drilled at the tip of the bucket operating arm 17 provided on the same arm 6, the bucket hoe 5 is attached as shown in FIG. Instead of the bucket, the base end of the machine frame 1 can be rotatably pivoted. Arm 6,
A long arm and a long boom can be used as the boom 18. In the figure, 19 indicates the operating cylinder of the operating arm 17, and 20 indicates the operating arm 1.
A link between the base of 7 and the arm 6, 21 is a pipe for the hydraulic motor 10, 24 is a cylinder for operating the arm 6, 25 is a cylinder for operating the boom 18, 26
27 is a crawler track for traveling of the backhoe 5, and 27 is a heavy cone.

Therefore, the water from the creek in the Saga Plain, etc. is drained, lime powder or cement powder 29 is spread in layers on the muddy bottom surface 28, the boom 18 and arm 6 are extended to the opposite bank, and the machine frame 1 is supported vertically by the cylinder 19. Then, by rotating the portal frame 3 in the direction of the arrow a in Fig. 4, immersing the same frame 3 from the bottom surface 28 to a depth of about 1 m, and moving it in the direction of the arrow b in Figs. 3 and 4, large and small cuts can be made. Leaves of plants such as reeds are removed by the claws 22 and 23.
Stems, roots, etc. are cut. Then, the stirring plate 4 rotates in a trajectory line 30 shown by the imaginary line in FIG. 4, and the cement powder 29 can be mixed and stirred in the mud in a layer with a depth of about 1 m. That is, when the stirring plate 4 rotates along the trajectory line 30 from the solid line position in FIG.
transports the cement powder 29 into the muddy soil, and moves the cement powder 29 into the fourth groove toward the groove-shaped space 31 formed by lowering the plate 4.
The mud and cement powder rotate and enter from the left side of the figure, and the stirring plate 4 of the gate frame 3 successively repeats this process to mix lime powder or cement powder into the mud. This mixed layer hardens to the extent that people can walk on it in about 1.5 hours, and fully hardens in 3 to 4 hours, allowing waterways,
It is possible to form roadbeds for temporary roads, etc. The amount of cement powder varies depending on the purpose, but it should be around 60Kg/ ^m3 . Such a mixing and stirring operation is performed by reciprocating in the width direction between both banks 32 and 33 by the long arm 6 and long boom 18 as shown in FIG. 3, and as shown by the imaginary line in FIG. Meandering shore 34,3
In 5, the above machine frame 1 is replaced with a bucket and the straight bank 3 is installed.
2 and 33, and by using a bucket instead of the machine frame 1, the waterway can also be corrected.

Since this project is structured as described above, Batsukuho 5
The above-mentioned ground agitator can be used instead of the bucket, and when it is located on the bank 33, both banks 32, 3 can be used.
By cutting plants such as reeds growing on the bottom surface 28 of the muddy soil between the long boom 18 and the long arm 6, the upper layer of the muddy soil can be evenly stirred and lime powder or cement powder can be evenly mixed into the upper layer. There is an advantage in that mixing and stirring can be carried out quickly and easily over a wide range.
