Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basic construction method for making a drainage channel and a basic ruler used in the basic construction method.

[0002]

2. Description of the Related Art Conventionally, when a drainage groove is formed by using a U-shaped groove block 1, before the drainage groove is first formed, a foundation 2 corresponding to the U-shaped groove block 1 used for this is installed. The usual method is to lay it out according to the plan, sequentially arrange the U-shaped groove blocks 1 on it, and carry out in the order of forming drainage grooves. Therefore, the process of laying the foundation 2 and arranging the U-shaped groove block 1 to form the drainage ditch was performed in separate steps, and during that time, weather and weather and other inconveniences were encountered and the construction period was increased. There were many troubles to grow up.

[0003]

DISCLOSURE OF THE INVENTION In the present invention, when laying a drainage groove, the installation of the laying material 16 which is the foundation 2 and the installation of the U-shaped groove block 1 are carried out as a simultaneous process, and a chain type continuous operation is performed. Has created a method to complete the drainage ditch all at once through a series of progressive processes.

[0004]

When a drain groove is formed by using the U-shaped groove block 1, the U-shaped groove block 1 is arranged so that the U-shaped groove blocks 1 are continuously arranged in accordance with the design according to the purpose. It is necessary to lay the laying material 16 of the foundation 2 according to the above at an inclination according to the design.

A laying material 16 which is a base 2 of the U-shaped groove block 1.
Has a sufficient width to support the weight of the U-shaped groove block 1 and has a minimum width, so it is necessary to continuously lay it with sand, mortar, concrete, crushed stone, etc. .

In order to make a drainage groove by using the U-shaped groove block 1, a water thread 14 corresponding to the slope formed by the upper surface of the U-shaped groove block 1 used first is stretched over the entire area of the drainage groove. With the water thread 14 as a reference, the laying material 16 to be the base 2 corresponding to the U-shaped groove block 1 used in parallel must be laid.

With the line of the water thread 14 as a reference, a base ruler 3 is made for continuously laying the laying material 16 of the foundation 2, and the laying material 16 is laid according to the base ruler 3.
By arranging the U-shaped groove blocks 1 and continuing the work in a chain manner, it is possible to lay a continuous foundation 2 and install drainage grooves by the U-shaped groove block 1.

The basic ruler 3 has the following structure. In order to make the width of the foundation 2 to match the U-shaped groove block 1, side guiders 4 for determining both sides of the foundation 2 are provided in parallel to the left and right sides, and the length thereof is longer than that of the U-shaped groove block 1.

Drainage laying direction 1 of the side guider 4
A jack bolt 6 for vertically adjusting the side guider 4 is erected vertically on the front end of 7, and an adjustment grip 7 is attached to the upper end and a ground plate 8 is attached to the lower end, and a lock nut 10 is used for fixing.

A mounting screw bolt 9 which stands vertically at a position slightly rearward of the jack bolts 6 of the left and right side guiders 4 and at the opposite position of the rear end is erected, and the height of the mounting screw bolt 9 is the height of the U-shaped groove block 1. It is higher than that.

In order to make the distance between the left and right side guiders 4 constant, a width determining angle 11 connecting both ends of both side guiders 4 is fitted into front and rear mounting screw bolts 9 and fixed with lock nuts 10.

The width-determining angle 11 can be fixed by expanding and contracting the length, and a level 12 is attached in the middle.
Make sure that the positions of the left and right side guiders 4 are horizontal so that they can be checked.

The width determining angle 11 is provided at the end of the drainage laying direction 17 which extends the U-shaped groove blocks 1 of the left and right side guiders 1 in sequence.
1. At the opposite end, the rear width determining angle 1
1, the front width determining angle 11 is mounted at a position slightly higher than the side guiders 4 on both sides via the spacer 5, and the rear width determining angle 11 is fixed to the rear side end guider 4 by the mounting screw bolts 9 on both sides. It is horizontally attached to the middle portion at a position higher than the upper surface of the side guider 4 by the height of the U-shaped groove block 1 and fixed by the lock nut 10.

For the mounting screw bolt 9 attached to the front part of the side guider 4, the guide antenna 13 is attached to the height of the U-shaped groove block 1 from the surface of the side guider 4 and the lock nut 10 is attached.
It is attached to and used to match the height with the water thread 14.

A handle 15 used for moving the base ruler 3 is provided on an upper portion of the mounting screw bolt 9.

[0016]

With the width-determining angle 11 of the basic ruler 3 having the above-described structure, the front and rear end intervals of the left and right side guiders 4 are set to the prescribed dimensions, and the water is extended to the height of the U-shaped groove block 1 of the drainage groove. The thread 14 and the lower surface of the rear width determining angle 11 are aligned, the jack bolt 6 attached to the front end of the side guider 4 is adjusted, and the height of the guide antenna 13 and the water thread 14 fixed to the attachment screw bolt 9 on the front side. And adjust the height of the left and right side guiders 4 horizontally while watching the level 12.

A laying material 16 is filled between the left and right side guiders 4, and is fitted to the upper surfaces of the left and right side guiders 4,
As shown in FIG. 2, a leveling plate 18 is used to smooth the upper surface of the laying material 16 to form a base 2 of the U-shaped groove block 1, and the U-shaped groove block 1 is set on the base 2.

Next, the foundation ruler 3 is installed in the drainage laying direction 1
7 Put the rear width determining angle 11 on the upper surface of the U-shaped groove block 1 just installed, adjust the jack bolt 6 to align the guide antenna 13 and the water thread 14, and set the level 1
Set the tips of the left and right side guiders 4 to the same level by using 2, and transfer the filling material 16. After that, while shifting the base ruler 3 in the drainage groove laying direction 17 along with the water thread 14, the base material 2 is filled with the laying material 16 to sequentially install the U-shaped groove block 1 and the laying of the foundation 2 alternately. Work in a chain manner to lay a drain.

[0019]

EFFECT OF THE INVENTION Conventionally, after the water thread 14 is stretched, the installation of the U-shaped groove block 1 and the setting of the foundation 2 of the U-shaped groove block 1 have been performed as separate steps. U-shaped groove block 1 by performing the groove installation basic method
The installation of and the setting of foundation 2 can now be performed as a continuous chain-type construction method.

Since the setting work of the foundation 2 and the installation work of the U-shaped groove block 1 can be simultaneously performed as a series of work in a chain type, the construction period is less affected by weather and weather.

The basic ruler 3 is the distance between the side guiders 4
Since the length of the width determining angle 11 and the position of the height of the guide antenna 13 can be freely changed, it can be applied to the installation of drainage grooves using various structures of the U-shaped groove block 1. is there.

Since the basic ruler 3 has a relatively light weight, it can be easily moved by human power.

By using the basic ruler 3, it has become possible for even an amateur to install a drainage ditch.
