The pair of press rollers 17 are located on the upper side of the press pin 15 The insertion of the pipe 4 between the pair of press-in rollers 17 is not performed properly because the elasticity of the elastic member 14 elastically provided on the pipe 4 is narrowed inward by the elasticity of the elastic member 14.

Therefore, at this time, when the cylinder 18 installed between the pair of pushing ports 15 is actuated, the pair of pushing ports 15 are opened to the side of the pushing pin 15 by the expanding force of the cylinder 18, The press-in roller 17 provided on the pipe 4 is also opened so that the pipe 4 is easily inserted between the pair of press-in rollers 17.

After the pipe 4 is inserted into the press-fitting device 8 as described above, the motor 16 installed behind each press-in roller 17 is driven. As shown by an arrow in FIG. 2, And the other motor is rotated in the counterclockwise direction, the pipe 4 sandwiched between the pair of press-in rollers 17 is pushed inward by the elastic force of the elastic member 14, 17 are rotated in opposite directions to each other, insertion into the soft ground 5 is performed.

When a hard layer is formed on the soft ground 5 in the process of press-fitting the draining material 3 into the soft ground 5 by using the press-fitting device 8 as described above, the housing 1 of the press- A hard layer can be easily inserted by using the auxiliary press-fitting device 20 installed on the upper part.

When the pipe 4 into which the draining material 3 is inserted is forcibly press-fitted into the soft ground 5 by using the auxiliary press-fitting device 20, the both clamping cylinders 26 are operated so that the both- Descending cylinder 22 is lowered by the lowering pressure of the ascending and descending cylinder 22 so that the clamping cylinder 24 installed on the ascending and descending steel plate 24 The pipe 4 clamped to the both side jaws 25 of the pipes 26 is lowered by the lowering pressure of the lifting cylinder 22 so that the pipe 4 can be easily press-fitted into the end layer.

When the pipes 4 are pulled out, when the respective motors 16 are rotated in the direction opposite to the direction in which the pipes 4 are inserted, the frictional force between the press- It will come out.

When the drainage material 3 is planted on the soft ground 5 as described above, the moisture contained in the soft ground 5 is absorbed by the moisture absorption paper 32 of the drainage material 3, 31, and the collected water moves up to the top of the draining material 3 due to the capillary phenomenon along the valley of the drain board 31.

Thus, the water that has climbed on the top of the draining material 3 is dried and evaporated by the solar heat and the wind to remove moisture. When the water of the soft ground 5 is removed, the ground subsides and becomes rigid so that civil engineering structures and buildings can be constructed as desired. In the case of another embodiment of the present invention shown in FIG. 6, when the pipe 4 is pressed into the soft ground 5, when the hard layer comes out of the soft ground 5, When two or three pairs of press-in rollers 17 are provided, the frictional force is increased and the press-in can be easily performed even on hard ground.

As described above, according to the present invention, the draining material for removing moisture contained in the soft ground can be easily press-fitted into the soft ground by a friction force of the press roller at a time, , The construction cost is reduced by shortening the working time and the working efficiency is improved.

In addition, when a hard layer occurs at the time of the improvement of the soft ground, when the hard layer comes out from the soft ground, the pipe can be pressed into the hard layer by the auxiliary press-fitting device. There is a very useful effect that can be improved hard.
