[0010]

[Embodiment of device]

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0011]   As shown in FIGS. 1 and 2, a water discharge pipe 3 is provided below the inclined dam 2 of the reservoir 1. The bottom gutter pipe 6 which is a part of the water discharge pipe 3 is connected to the inlet of the water discharge pipe 3. Along the slope of the dam 2 on the reservoir side, the upper and lower gutter pipes 4 and 4 And 5 are provided.

[0012]   At the upper part of the peripheral wall portion of the upper gutter pipe 4, the intake pipes 7 and 8 are arranged at predetermined intervals in the length direction. Are respectively connected to the intake pipes 7 and 8 and the intake gates 9 and 10 ( For example, a sluice gate) is attached, and these gates 9 and 10 have a common operation lock. The operation handle 12 at the upper end of the operation rod 11 is connected to Therefore, both gates 9 and 10 can be opened and closed sequentially.

[0013]   The upper gutter pipe 4 is arranged in advance along the slope of the dam 2 on the reservoir side. Connect the lower end of the upper gutter pipe 4 to the upper end of the lower gutter pipe 5 at the site. ing.

[0014]   The lower end portion of the lower-stage slant pipe 5 is bent vertically downward so that its lower end (the outlet portion 5a ) Is integrally connected to the center upper part of the peripheral wall portion of the bottom gutter pipe 6 by welding at the factory. ing. The lower sloping tube 5 is bent so that the lower end and the upper end are eccentric, and The center axis of the gutter pipe 4 and the center axes of the water discharge pipe 3 and the bottom gutter pipe 6 are displaced in a plane. It is installed in.

[0015]   The upper part of the peripheral wall of the lower gutter pipe 5 is located vertically above the central axis of the bottom gutter pipe 6. Then, the intake pipe 13 is connected, and the intake gate 14 ( For example, a sluice gate) is attached, and the operating rod 15 of this gate 14 is The operating rod 15 is arranged in parallel with the operating rod 11 without interference. The gate 14 can be opened and closed by operating the operation handle 16 at the upper end of the ing.

[0016]   The inner surface of the peripheral wall of the bottom gutter pipe 6 facing the outlet portion 5a of the lower gutter pipe 5 has a lower stage. The water cushion recess 36 for receiving the discharge flow A from the slant pipe 5 is formed. Has been done.

[0017]   As shown in detail in FIGS. 4 and 5 (a), the recess 36 has an open upper surface. Is formed in a rectangular box shape and has a recessed portion in the opening 6a formed in the peripheral wall portion of the bottom gutter pipe 6. It can be formed by integrally fixing the material by welding. The above The recessed portion 36 is a hemispherical recess as shown in FIG. 5B or a rear portion as shown in FIG. 5C. It can be a hemispherical depression that is gently curved in one direction. The recess 36 is always Water is accumulated at the water level L, and the water is in the form of a waterfall.

[0018]   An installation leg 33 is fixed to the bottom gutter pipe 6, and the tip of the bottom gutter pipe 6 is That is, the bottom gutter gate 17 is provided at the side end 6B opposite to the connection end 6A of the water discharge pipe 3. There is. As shown in detail in FIG. 3 and FIG. Gate) 18, support frame 19, hoisting spindle 20, spindle bearing 21 And spindle operation handle 22 and attached to the bottom gutter pipe 6 at the factory It has been burned. In addition, in the upper part of the peripheral wall portion of the bottom gutter pipe 6 near the gate 17. A reservoir plug 23 is attached via an attachment pipe 24.

[0019]   The gutter pipes 4, 5 and 6 are connected to the intake gates 9, 10, 14 and the reservoir pond 23. It is filled with concrete up to the bottom, but in some cases it is underwater without being filled. You may leave it exposed to.

[0020]   In addition, 25, 26, 27, 28 are dust removing screens for gates, and 29 is an upper gutter pipe. 4. Air pipe connected to the upper end of 4, 30 is stairs for maintenance and inspection, 31 is operation rod support A base 32 is an operation rod bearing base.

[0021]   The above-mentioned bottom gutter pipe 6, lower stage gutter pipe 5, bottom gutter gate 17, intake pipe 13, reservoir pond 23, intake The water gate 14 and the installation legs 33 are manufactured and assembled in the factory, and It is finished as one.

[0022]   Therefore, the bottom gutter pipe 6 and others are transported from the factory to the installation site in the assembled state and installed. At the attachment site, it is placed on the foundation 34, centered and positioned, and bottomed at the inlet of the water discharge pipe 3. It can be installed by an extremely simple work of simply fitting and connecting the end 6A of the gutter pipe 6. , The field work can be significantly reduced.

[0023]   Then, at the time of installation, the mounting legs 33 of the gutter pipe 6 are connected to the bottom gutter pipe 6 by concrete. It is also embedded in the upper part, and further, the upper-stage sluice pipe 4 is connected to the lower-stage sluice pipe 5, and the intake gate The operating rod 15 is connected to 14.

[0024]   In addition, when viewed from the plane of FIG. 2, the lower stage gutter pipe 5 has the upper end thereof having the same axis line as the bottom gutter pipe 6. Alternatively, the lower end portion of the upper gutter pipe 4 may be bent at the upper position. In addition, the upper gutter pipe The number 5 can be plural.

[0025]   On the other hand, the recessed part 36 formed in the bottom gutter 6 is always in a water pool at the water level L. Therefore, the discharge flow A from the outlet portion 5a of the lower sluice pipe 5 is It is received by a waterhole-shaped water pool, and this water pool functions as a water cushion. Therefore, the discharge water pressure cannot be directly received by the inner surface of the peripheral wall of the bottom gutter pipe 6. It As a result, the durability of the bottom gutter 6 is dramatically improved.

[0026]   If the recess 36 has a hemispherical shape as shown in FIGS. 5B and 5C, it is received. Since the discharge water A is distributed almost evenly around the recess 36, the bottom gutter pipe 6 and the recess The durability of the portion 36 is further improved.

[0027]   In addition, the recessed portion 36 opens the opening 6a in the bottom gutter pipe 6 and fixes the recessed member by welding. Since the structure is simple and the manufacturing cost is low, the existing bottom gutter pipe It is also possible to add 6 by adding a slight modification.

[0028]   The present invention is not limited to the above-described embodiment, but the slant pipes (4, 5) may be used. The upper gutter pipe 4 and the lower gutter pipe 5 are not divided, and the bottom gutter pipe 6 is provided at the inlet of the discharge pipe 3. Not connected type gutter pipe structure, that is, a single inclined gutter pipe on the peripheral wall of the water discharge pipe 3. It goes without saying that it can also be applied to the gutter pipe structure of the water intake equipment in which (4,5) is directly connected. Nor.

[0029]

[Effect of device]

  As is apparent from the above description, the device of claim 1 is formed in the water discharge pipe. Since the depression is always in the state of water accumulation, the discharge flow from the outlet part of the slant pipe is It is received by the waterhole-shaped water pool in the depression, and this water pool is used as a water cushion. Since it performs the function of water discharge, the discharge flow pressure is directly received by the inner surface of the peripheral wall of the discharge pipe. The durability of the water discharge pipe will be dramatically improved.

[0030]   According to the second aspect of the present invention, the recess formed in the bottom gutter pipe is always in a water pool state. Therefore, the discharge flow from the outlet of the lower sluice pipe is received by the waterhole-like water pool in the depression. It will be stopped, and this water pool will function as a water cushion. The pressure cannot be directly received on the inner surface of the peripheral wall of the bottom gutter, and the durability of the bottom gutter is improved. Will be dramatically improved.
