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 pouring equipment used in chemical drainage methods usually uses only one mandrel, which is inefficient.
Additionally, some devices equipped with a plurality of mandrels are in use, but the work of inserting the mandrels and moving the device takes time and poses problems in terms of efficiency.

The present invention has been made to solve the above-mentioned drawbacks, 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 chemical 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 pair of mandrels 3, a pair of drain material supply mechanisms 4, and a pair of leaders 5. and a pair of guide parts 6.

The casting machine main body 2 is a power shovel from which the packet has been removed, and includes an arm 9 that is supported by the main body 2a via a pin 7 and swings by being driven by a cylinder 8, and a pin 10 attached to the arm 9.
The arm 12 is supported via a cylinder 11 and swings by being driven by a cylinder 11.

As shown in detail in FIGS. 2 and 3, a pin 13 is inserted into the tip of the arm 12 using a pin hole for supporting the packet.
Fixed.

Each mandrel 3 is formed from a square pipe having appropriate rigidity, and a joint fitting 14 is fixed to the inside of its upper end by welding or the like.

An elongated hole 16 is provided in the arm portion 15 of the joint fitting 14, and the elongated hole 16 fits into both ends of the pin 13, respectively.

Each drain material supply mechanism 4 includes a bracket 17 attached to the joint 1 and the metal fitting 14, a drain material 18 wound in a roll around a core rotatably supported by the bracket 17, and a drain material 18 to be fed out. It consists of a guide roller 19 that guides the material 18.

The guide roller 19 is rotatably supported by the mandrel 3.

Each leader 5 is transformer-shaped, and its base is fixed at a position corresponding to each mandrel 3 on the main body portion 2a of the driving machine main body 2.

A leader support leg 20 for supporting and fixing the leader 5 is attached to the lower surface of the leader 5.

The leg portions 21 of the leader support legs 20 are moved up and down by hydraulic pressure.

Each guide portion 6 is attached to the tip of the leader 5 via a hinge 22.

Four rollers 23 are rotatably supported on this guide portion 6.

The rollers 23 are for holding the mandrel 3 vertically and guiding the mandrel 3 in the vertical direction when driving the mandrel 3.

The guide portion 6 and the leader 5 are connected by a wire 24, and a wire winder 25 is provided in the middle of the wire 24.

When setting the mandrel 3 in the guide part 6, open the guide part 6 to the position shown by the dashed line in FIG. 1, insert the tip of the mandrel 3 between the rollers 23, and operate the winder 25. The guide portion 6 is pulled and set by the wire 24 to the position indicated by the solid line.

In this state, the mandrel 3 is vertical at the guide portion 6 and elastically curved above it as shown in FIG. , the shape of the mandrel 3 curved part is pin 7
In addition to making it nearly circular arc-shaped with the center at It is possible.

The rolled material 18 is supplied from the upper end of the mandrel 3.

The drain material 18 fed out through the guide roller 19 is inserted into the mandrel 3 and pulled out by an appropriate amount from the lower end of the mandrel 3.

In this case, if a tension panel 26 having spring properties is provided to press the outer periphery of the rolled drain material 18, it is possible to prevent the winding core of the rolled drain material 18 from rotating more than necessary.

Chemical drain material placing device 1 in which the mandrel 3 is set in this way and the drain material 18 is inserted into the mandrel 3
The drain material 18 is placed in the following manner.

The casting machine main body 2 is moved to a predetermined location by self-propulsion (in this case, the legs 21 are at the position indicated by the dotted line), the legs 21 are lowered until they touch the ground, and the leader 5 is horizontally supported and fixed. When the cylinder 8 is actuated and the arms 9 and 12 are swung clockwise from position A shown by the solid line in Figure 1 using the pin 7 as a fulcrum, the arms 9 and 12 move to positions B and C shown by the chain line in the figure. do.

At position B, pin 13 is on a horizontal line passing through the center of pin 7.

The mandrel 3 is curved between positions A and B, but becomes vertical at the guide portion 6, and the mandrel 3 is driven perpendicularly to the ground.

In this case, while the arms 9 and 12 pass the position B and reach the final swing position C, the pin 13 is inside (
However, since the arm portion 15 is fitted with the pin 13 through the long hole 16 and the pin 13 moves within the long hole 13, the mandrel 3 and the roller 23 are forced laterally. No excessive force is applied, and the driving progresses smoothly.

After the arms 9, 12 reach position C and complete driving, when the arms 9, 12 are swung counterclockwise, the mandrel 3 is pulled out, but the drain material 18 is left in the ground.

This is because the drain material 18 taken out from the lower end of the mandrel 3 during driving is buried in the soil.

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

When one pouring operation is completed, the legs 21 are raised and separated from the ground, and the pouring machine main body 2 moves by itself to the next pouring position.

At this position, the drain material 18 is cast in the same manner as described above.

Thereafter, by repeating this process, predetermined pouring can be carried out extremely efficiently in a short period of time.

In the above explanation, an example was described in which the mutual relationship between the arms 9 and 12 is fixed and the concrete is oscillated to perform pouring.
As shown in FIG. 4, the arm 9 is first fixed at the position shown by the solid line, and the cylinder 11 is actuated to swing the arm 12 from the position A shown by the solid line to the position D shown by the chain line. Pouring may be performed by operating the arms 9 and 12 to swing from position D to position E.

In this case, the league 5' is shorter than in the case of Fig. 1, and the amount of curvature of the mandrel 3 can be reduced, so the force for vertically straightening the mandrel 3 with the guide part 6 is reduced, and the bending strength of the mandrel itself is reduced. is small.

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 easily and quickly position the device at the pouring position using the self-propelled pouring machine main body (power shovel) and pour drain material one after another in a short time. This makes it possible to greatly improve efficiency, and the structure is simple.
