Waterway B
And a height setting means 6 for holding a space formed between them.

More specifically, the bottom mold 4 is made of synthetic resin or steel, and is made of, for example, an elastic pipe made of vinyl chloride or the like. The traction means 7 has a slightly larger diameter, is formed by cutting one side surface of the tube 4 in the longitudinal direction at least with a width smaller than the diameter of the tube body, and is capable of extending and contracting opposing cut ends.
And is inserted into the waterway of the culvert-type side groove body 1 after being pulled against the elastic force, and is then inserted and held on the waterway bottom B of the culvert-type side groove body 1 by the return elasticity of the pipe itself. , And a space is formed between the bottom surface of the pipe 4 and the channel B of the culvert-side gutter 1.

Next, as shown in FIG. 3 and FIG. 4, the traction means 7 has a tan buckle 8 in the center, and is screwed to the tan buckle 8 and the tip is bent in an L-shape. It is composed of a pair of screw shafts 9a and 9b composed of a combination of screws.

As shown in FIG. 7, the pressing means 5 has a tan buckle 13 at the center thereof.
3, a pair of screw shafts 15a, 1 comprising a combination of reverse screws having square stoppers 14, 14 at their ends.
5b and a pair of U-shaped stoppers 14 and 14 which are inserted and held in the screw shafts 15a and 15b so as to be movable in the axial direction, are locked in a non-rotatable manner, and are locked in a non-removable manner. It is composed of pressing members 17, 17 and compression springs 16, 16 as urging means for elastically pressing the pressing members 17, 17 outwardly against both ends of the tambuckle 13.

The shaft 24 is formed by screwing.

Thus, the height setting means 6 is pressed by rotating the tambuckle 25 between the inner bottom of the tube 4 and the ceiling of the unit culvert-type side groove 1, and the tube 4
Is the distance from the channel bottom B at both ends in the longitudinal direction of the unit sewer-type gutter 1, that is, from the bottom of the unit sewer-type gutter 1 to the water bottom B.
The heights h1 and h2 can be set to a predetermined gradient and held.

Next, a description will be given of a manufacturing method for manufacturing a unit-side groove body having a sloping channel using the manufacturing apparatus configured as described above.

First, the procedure for setting the pipe 4 as the bottom type in the unit culvert type side groove 1 will be described. As shown in FIG. 4, opposing cut ends of the pipe 4 are pulled by the retractable pulling means 7 into the water channel of the unit-drain-type gutter 1 installed in a horizontal state.

Therefore, the unit-side groove body 1 formed in advance is
The pipe 4 as a bottom mold made of an elastic body is pulled in the width direction by the pulling means 7 on the inner wall H of both water paths above the water channel surface B of the water channel B to reduce its diameter, and then inserted into the water channel of the unit-side groove body 1 and then again. The diameter is increased, and the unit is closely joined to the inner wall H of the water channel of the unit sewer type side groove body 1 in a pressed state by a return elastic force in the width direction to set a gradient state over the entire length.

Next, as shown in FIG. 5, the pipe body 4 set and held at a predetermined inclination angle is pressed against the inner wall H of the culvert type gutter by the pressing means 5 and pressed and held. A space is formed between the bottom surface of the pipe and the channel bottom B of the culvert-type gutter 1. When the pipe 4 having the same diameter as the channel width is used, the inner wall of the pipe 4 is pressed and held by the pressing means 5 without using the traction means 7 to reduce the diameter. In this case, since the diameter of the pipe 4 is not reduced by the traction means 7, the bottom surface of the pipe 4 can obtain an arc having the same diameter as the width of the water channel.

Then, as shown in FIG. 6, at least both ends of the pipe 4 held and pressed by the height setting means 6 so that a gradient is formed with respect to the channel bottom B of the culvert-type side groove 1. It is adjusted and held in the height direction of the culvert-side gutter 1.

Next, as shown in FIG. 8, the space is filled with concrete C in a state where the unit sewer-type gutter 1 is set upright, so that the channel sewer of the unit sewer-type gutter 1 is filled. A gradient is formed in B.

As described above, by using, for example, a vinyl chloride tube 4 made of a general elastically deformable synthetic resin tube as the bottom mold 4, at least one side surface of the tube 4 is formed. It can be formed by simple processing of simply cutting in the longitudinal direction with a width smaller than the diameter, and this is temporarily held on the water channel surface B of the unit sewer type side groove body 1 using its own elastic force. In this state, it can be securely inserted and held.

In addition, even if the dimensions of the inner wall H of the waterway surface vary, the pressing body 17 can be elastically pressed and temporarily held by a predetermined pressure. Instead of the pressing body 17, the inside of the tube 4 is pressed by the stopper 14 to reliably press and hold the tube set at a predetermined inclination angle.

Further, since a gradient space is formed by the pipe 4 pressed and held above the water channel bottom B of the unit culvert-type gutter 1 formed in advance, the unit culvert-type gutter 1 in this state is formed. It is possible to easily form a slope waterway simply by placing the concrete in an upright state and filling the space with concrete C, and mass production in a factory becomes possible.

The present invention has the following effects.

(A) According to the first aspect of the present invention, when the unit-side grooves are sequentially connected and joined, the channel bottoms at the joint surfaces coincide with each other. It is possible to lay the culvert-type gutter connected in accordance with a predetermined length by simply burying it horizontally, thereby improving the construction work on site.

(B) According to the second aspect of the present invention, the space is formed by the bottom mold pressed and held above the water channel surface of the previously formed unit sewer type side groove body. The inclined channel surface can be easily formed only by filling the concrete in the space with the mold side groove body standing upright, and mass production in the factory is possible.

(C) According to the third aspect of the present invention, the space is formed only by holding the bottom molds in close contact with the inner walls of the water passages above the water passage surface of the unit-drain-type gutter in a gradient state. Since it can be formed, a unit sewer type gutter having a sloped waterway can be easily mass-produced in a factory.

(D) According to the fourth aspect of the invention, one side surface of the tubular body whose bottom mold is made of a general elastically deformable synthetic resin tube is cut in the longitudinal direction at least with a width smaller than the diameter of the tubular body. It can be formed by only simple processing, and is held on the water channel surface of the unit sewer-type gutter using its own elastic force, and can be reliably inserted and held in this state.

(E) According to the fifth aspect of the present invention, the pressing body can be elastically pressed by a predetermined pressure and temporarily held, even if the inner wall of the water channel varies, so that the tank is kept in this state. By rotating the buckle, the inside of the tube is pressed by the stopper instead of the pressing body, and the tube set at a predetermined inclination angle can be reliably held.
