Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chemical drain material casting device used in a chemical drain construction method.

Here, the term "drain material" refers to a drainage material that is driven into the ground to improve soft ground, and a drain material made of nonwoven fabric made from chemically synthetic fibers is called a chemical drain material.

By driving this drain material into the ground, water in the ground is transmitted through the drain material and discharged to the ground.

Conventional casting equipment used in the chemical drainage method usually uses only one mandrel and is inefficient.
In addition, some devices equipped with a plurality of mandrels are used, but there is a problem in that it takes time to insert the mandrels and move the device.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide a highly efficient chemical drain material casting device that can sequentially cast a large number of drain materials in a predetermined arrangement in a short period of time.

Next, embodiments of the invention will be described with reference to the drawings.

In FIG. 1 showing the overall outline of the device, 1 is a chemical drain material casting device, which includes a casting machine body 2, a link 3, a horizontal arm 4, a mandrel 5, and a drain material supply mechanism 6.
, a leader 7 , and a guide section 8 .

These links 3, horizontal arm 4, mandrel 5, drain material supply mechanism 6, leader 7, and guide section 8 are each provided in pairs facing each other in the direction perpendicular to the plane of the paper.

The casting machine main body 2 is a power shovel from which the packet has been removed, and includes an arm 11 that is supported on the main body 2a via a pin 9 and is driven by a cylinder 10 to swing, and a cylinder 13 that is supported on the arm 11 via a pin 12. It is provided with an arm 14 that is driven by and swings.

Each link 3 is connected to the main body 2a via a pin 15,
Each horizontal arm 4 is connected to the tip of an arm 14 via a pin 16.

The other end of each link 3 is connected to a protrusion 18 of the horizontal arm 4 via a pin 17.

In this case, each pin 9, 15, 16, 17 corresponds to a vertex of a parallelogram link, and the horizontal arm 4 is parallel to the ground.

Each mandrel 5 is formed from a square pipe having appropriate rigidity, and a guide member 19 is fixed to the upper part of the mandrel.

The guide member 19 is fixed to the mandrel 5 using a pin,
This is carried out using a hydraulic chuck, an electric chuck, etc., so that the guide member 19 can be changed in position with respect to the mandrel 5.

The distal end of the horizontal arm 4 is slidably supported by this guide member 19.

The link 3, the horizontal arm 4, and the guide member 19 are connected to the arm 1.
This constitutes a transmission mechanism that transmits only the force in the vertical direction to the mandrel during the swinging of the mandrels 1 and 14.

Each drain material supply mechanism 6 includes a bracket 20 attached to a guide member 19, and a drain material 21 wound in a roll shape around a core rotatably supported by the bracket 20.
and a guide roller 22 that guides the drain material 21 being fed out.

The guide roller 22 is rotatably supported by the mandrel 5.

Each leader 7 is truss-shaped and is fixed at a position corresponding to each mandrel 5 on the main body 2a.

A leader support leg 23 for supporting and fixing the leader 7 is attached to the lower surface of the leader 7, and the leg portion 24 of the leader support leg 23 is moved up and down by hydraulic pressure or a screw method.

Each guide portion 8 is fixed to the tip of the leader 7.

Four rollers 25 are rotatably provided on this guide portion 8.

The rollers 25 are for holding the mandrel 5 vertically and guiding the mandrel 5 in the vertical direction when driving the mandrel 5.

The rolled drain material 21 is supplied from the upper end of the mandrel 5.

The drain material 21 fed out via the guide roller 22 is inserted into the mandrel 5 and pulled out by an appropriate amount from the lower end of the mandrel 5.

In this case, if a tension panel 26 having spring properties is provided to press the outer periphery of the roll-shaped drain material 21, it is possible to prevent the winding core of the roll-shaped drain material 21 from rotating more than necessary.

Drain material 21 is placed by the chemical drain material placing device 1 having such a configuration as follows.

The casting machine main body 2 is moved to a predetermined location by self-propulsion (in this case, the legs 24 are at the position indicated by the dotted line), the legs 24 are lowered until they touch the ground, and the leader 7 is horizontally supported and fixed. When the cylinder 10 is actuated to swing the arm IL14 clockwise from the position indicated by the solid line in FIG. 1 using the pin 9 as a fulcrum, the horizontal arm 4 moves from position A to position B while maintaining its horizontal posture.

As described above, this horizontal arm 4 is slidably fitted into the guide member 19 fixed to the mandrel 5 which is held perpendicularly to the guide part 8, so that the horizontal arm 4 moves from position A to position B. Due to the shifting movement, the mandrel 5 is driven perpendicularly to the ground.

When the arm IL14 is swung in the opposite direction to that described above after driving the required amount of the mandrel 5 into the ground in this way, the mandrel 5 is pulled out, but the drain material 21 is left in the ground.

This is because the drain material 21 pulled out from the lower end of the mandrel 5 during driving is buried in the soil.

In this way, the drain material 21 can be cast easily and smoothly in a short time.

If the length of the mandrel is so long that it is necessary to move the arm 11.14 up and down several times, once the mandrel is driven into the ground, the guide member 19 is released from the mandrel 5 and the arm is raised. By this, the guide member 19 is slid upward along the mandrel while leaving the driven mandrel as it is, and the guide member 19 is moved upward at the raised position.
By fixing the mandrel to the mandrel, even a long mandrel can be driven into the ground in several parts.

When one pouring operation is completed, the legs 24 are raised and removed from the ground, and the pouring machine main body runs two laps to move to the next pouring position.

At this position, the drain material 21 is placed in the same manner as described above, and by repeating this operation, the specified placement can be carried out extremely efficiently in a short period of time.

Another example is shown in FIG.

In this example, a guide member 28 having a long hole 27 is fixed to the upper part of the mandrel 5, and a pin 29 at the tip of the arm 14 is engaged with the long hole 27.

At the time of pouring, the arm 11 is first fixed at the position shown by the solid line, and the cylinder 13 is actuated to swing the arm 14 from the position A shown by the solid line to the position C shown by the chain line.
0 to swing the arms 11 and 14 from position C to position D to perform pouring.

In this process, the pin 29 that transmits the pressing force to the mandrel 5 moves in the horizontal direction, but the amount of movement becomes small, so the mandrel 5 does not curve significantly, and the guide part 8 near the ground surface moves the mandrel 5. can be driven perpendicular to the ground.

In this case, the link 3 and horizontal arm 4 as in the previous example are not required, and the structure is simplified.

Also, the leader 7' becomes shorter.

Note that the present invention is also applicable to the casting of paper drain materials.

As described above, according to the present invention, it is possible to position the device at the pouring position using the self-propelled pouring machine body (power shovel) and pour drain material one after another in a short time, thereby improving efficiency. can be significantly improved, and the work is extremely easy.
