Description

  The present invention relates to a pump gate facility in which a pump gate is installed in a drainage gate or drainage pipe that forms a part of a drainage channel, and in particular, a reduction in construction cost and a pump using a management bridge. The present invention relates to a gate facility with a pump that realizes ease of inspection and maintenance.

As shown in FIG. 7, in order to guide and guide the pumped gate that goes up and down on the upstream side outside the pressure regulating water tank 102 provided in the drainage lock gate or the drainage pipe 101 constituting a part of the drainage channel. The gate pillar structure 103 is constructed. The gate pillar structure 103 has side pillars on the left and right, and has a structure in which a ceiling wall 103a is horizontally placed between the upper ends of the left and right gate pillars.
Guide grooves for guiding the left and right ends of the pumped gate that moves up and down are formed inside the both side columns of the gate column structure, respectively. In addition, an elevating mechanism for elevating and lowering the gate with a pump is installed on the ceiling wall 103a between the upper ends of the left and right gate pillars.
In addition, a management bridge 105 is laid across the water channel 104 near the pumped gate. The management bridge 105 is attached at a position where the gate with the pump that moves up and down does not hit.

However, in the case of the above-mentioned gate post structure, when removing for maintenance of the door body or removal for maintenance of the pump, the ceiling wall is horizontally placed above the equipment, so this ceiling wall is obstructive. Therefore, it was difficult to work with cranes.
In addition, when constructing the above-mentioned gate pillar structure, it is necessary to construct a ceiling wall, and it is necessary to construct an upper part of a side pillar that is connected to the ceiling wall, resulting in an increase in the quantity of concrete and the amount of reinforcing bars used. It takes time and effort, and the construction cost is high.
In addition, the management bridge was provided at a position where it would not interfere with the raising and lowering of the pump, but when checking the pump, it was lowered into the water channel or pulled up to a predetermined position, and the work scaffold was assembled and worked.

  In view of the above problems, the present invention was created to solve the problems, and the object of the present invention is to reduce construction costs and to inspect and maintain pumps using a management bridge. The object is to provide a gate facility with a pump that can realize the ease of inspection and maintenance.

  In order to achieve the above-mentioned object, the invention according to claim 1 is provided on the both side walls on the upstream side outside the pressure regulating water tank provided in the drainage sluice or drainage drainage pipe constituting a part of the drainage channel. The side pillars of the gate pillar structure are constructed adjacent to each other, and guide grooves are formed in the vertical direction to guide the left and right sides of the pumped gate that goes up and down on the side pillar and the side wall of the lower water channel. A gate elevating mechanism that raises and lowers the gate with a pump is installed on both sides of the upper side of the pump, and a management bridge is horizontally installed above the pump elevating path of the pumped gate and a part of the management bridge located on the pump elevating path is opened and closed. It consists of freely provided means.

  Further, the invention of claim 2 is provided on the side walls on the upstream side of the inside of the pressure regulating water tank provided in the drainage lock or the drainage drain pipe constituting a part of the drainage channel, and on the side wall of the lower side of the channel connected to the side wall. A pump that forms guide grooves to guide the left and right ends of the pumped gate that moves up and down in the vertical direction, and has a gate lifting mechanism that raises and lowers the pumped gate on both sides above the pressure regulating water tank. A management bridge is installed on the upper side of the hoistway of the attached gate pump and a part of the management bridge located on the hoistway of the pump is provided so as to be openable and closable.

As is clear from the above description, according to the gate equipment with a pump according to the first and second aspects of the invention, when performing removal for maintenance of the door body and removal for maintenance of the pump, Since there is no ceiling wall above the facility, the use and placement of cranes and cargo handling equipment are facilitated, and workability can be improved.
In addition, since it is not necessary to construct the ceiling wall and the upper part of the side pillars that lead to the ceiling wall, the amount of concrete and rebar is reduced, and the number of man-hours required for construction is reduced. In addition, the construction work time can be shortened.
In addition, the pump removed from the gate can be placed on the management bridge, and the pump can be inspected using the management bridge. There is no need to assemble a work scaffold and work can be facilitated.

  Moreover, according to the gate equipment with a pump of Claim 2, since the side wall of a pressure regulation water tank can be utilized in addition to said effect, construction of a side pillar can be made unnecessary and reduction of the quantity of concrete and the amount of reinforcement used can be reduced. Further efforts can be made.

  Further, in the case of claim 3, the gate can be raised by extending the cylinder upward, and the gate with pump is lowered by utilizing the dead weight of the gate and the pump by contracting the cylinder downward. Can be fully closed.

  Moreover, in the case of Claim 4, the gate with a pump can be raised / lowered reliably using the meshing of the rack beam and the rack type elevator.

  Hereinafter, the present invention will be described more specifically based on the best mode for carrying out the invention described in the drawings.

[Best Mode-1]
Here, FIG. 1 is a sectional side view of a gate equipment with a pump, FIG. 2 is a left half view of FIG. 1 as viewed from the arrow A, a right half is a view of arrow B of FIG. 1, and FIG. 3B is a cross-sectional side view of the structure to which is attached, FIG. 3B is the left half side view of FIG. A, the right half side is the B arrow view of FIG. It is a sectional side view.

  In the figure, a gate 1 with a pump is used to remove water from an upstream water channel 2a adjacent to the outside of a pressure regulating water tank 3a provided in a drainage sluice gate or a drainage culvert pipe 3 constituting a part of the drainage channel. It is forcibly discharged to the pressure regulating water tank 3a provided on the inflow side of the drainage lock or drainage pipe 3 on the side waterway 2b side, and has a structure in which the pump 6 is attached to the gate 1a. The water channel 2 is installed in the transverse direction. The gate with pump 1 has a structure that opens and closes the water channel 2 by raising and lowering a gate 1a as a door body. The drainage lock or the drainage lock pipe 3 is a culvert structure provided across the river bank, and the drainage lock pipe is a small culvert compared to the drainage lock.

  The gate 1 with a pump raises the gate 1a during natural drainage and drains water during forced drainage, and uses the pump 6 attached to the gate 1a with the gate 1a closed during forced drainage. Is forcibly drained to the pressure regulating water tank 3a provided on the inflow side of a drainage drainage lock or drainage drainage pipe 3 serving as a downstream water channel 2b.

  The gate 1a is composed of a rectangular and plate-like skin plate, vertical and horizontal reinforcing girders attached to the surface of the skin plate facing the upstream water channel 2a. The skin plate of the gate 1a is reinforced by these reinforcing girders to increase the rigidity.

  On the left and right sides of the water channel 2 where the gate 1 with a pump is installed, that is, on both side walls on the upstream side outside the pressure regulating water tank 3a provided on the inflow side of the drainage lock or drainage pipe 3, Side pillars 4 are respectively constructed adjacent to the pressure-regulating water tank 3a. That is, the left and right side columns 4 are integrally constructed adjacent to the left and right side walls of the pressure-regulating water tank 3a.

  Since the side pillar 4 having the non-post pole structure has no ceiling wall between the upper ends of the left and right side pillars as in the case of the gate pillar structure, the structure is simplified and the construction cost is greatly reduced. In addition, until now, when removing the gate 1 with a pump using a crane or the like, the height of the gate pillar must be set to a crane work or other equipment should be used so that the ceiling wall is not obstructed. However, since there is no ceiling wall as shown in FIG. 5, the crane a can be used, and the removal work of the pumped gate 1 can be performed efficiently.

  Guide grooves 2c for vertically moving and guiding the left and right ends of the pumped gate 1 are formed in the vertical direction on the left and right side columns 4 and the lower water channel side walls. The gate 1a is structured to move up and down along the guide groove 2c. Rollers 1b around the horizontal axis parallel to the transverse direction of the water channel 2 that reduce sliding resistance with the guide groove 2c are respectively provided at the left and right ends of the gate 1a. It can be moved up and down smoothly along the groove 2c.

  On both sides of the upper side of the pumped gate 1, gate lifting mechanisms 5 that lift and lower the pumped gate 1 are provided. The gate elevating mechanism 5 is composed of a cylinder 5b that elevates upward and downward and moves up and down the pumped gate 1 via a wire rope 5a connected to the pumped gate 1 at one end.

  Between the upper parts of the left and right side pillars 4 which are the upper side of the gate 1 with pump, a mounting girder 5c is provided horizontally in the width direction of the gate 1a. Both ends of the mounting girder 5c are connected and supported on the upper side of the left and right side columns 4, and the cylinders 5b are respectively mounted on the left and right sides of the mounting girder 5c upward. The upper side of each cylinder 5b is attached, for example, with a hinge structure around a horizontal axis.

  A sheave 5d is attached to the tip of the piston rod that expands and contracts in each cylinder 5b. Each sheave 5d is rotatable about a horizontal axis in the width direction of the gate 1a. Each of the left and right sheaves 5d is provided with an intermediate side extending upwardly of the wire rope 5a, one end of which is connected to the pumped gate 1, and the intermediate side extending upward of the wire rope 5a is the upper side of the circular shape of each sheave 5d. The other end of the wire rope 5a that is turned downward on the half side and extends downward is connected to and fixed to a fixture 5e on the lower side column 4 on the lower side of the cylinder 5b.

  When the piston rod of the cylinder 5b extends upward, the sheave 5d moves upward, and when the sheave 5d moves upward, the intermediate side of the wire rope 5a is pushed upward. At this time, since the other end of the wire rope 5a is connected and fixed to a fixing tool 5e below the side column 4 that does not move, when the intermediate side of the wire rope 5a is pushed upward, the wire rope 5a follows the wire rope 5a. One end side of 5a is moved upward, and a mechanism for pulling up the gate 1 with pump to which the one end side is connected is lifted by one end side of the wire rope 5a moving upward.

  On the contrary, the sheave 5d moves downward when the piston rod that the cylinder 5b has extended contracts downward, and the sheave 5d moves downward so that the intermediate side of the wire rope 5a is connected to the wire rope 5a. Since the dead weight of the pumped gate 1 is acting on one end of the shaft, it moves downward together with the sheave 5d. At this time, since the other end of the wire rope 5a is connected and fixed to a fixture 5e below the side column 4 that does not move, the wire rope 5a follows when the intermediate side of the wire rope 5a is lowered downward. The one end side of the wire moves downward, and the one end side of the wire rope 5a moving downward is a mechanism for pulling down the pumped gate 1 connected to the one end side.

  Since the cylinder 5b pushes up and lowers the intermediate side of the wire rope 5a whose one end is connected to the gate 1 with the pump and the other end is fixed, the gate 1 with the pump has 2 of the expansion / contraction speed of the piston rod of the cylinder 5b. Ascend and descend at double speed.

  A connector 1c to which one end side of a wire rope 5a for raising and lowering the gate 1a is connected is attached to the upper end of the gate 1a. For example, two connecting tools 1c are attached to the left and right sides of the upper end.

  A pump 6 is attached to the gate 1a on the surface of the lower part of the gate 1a facing the upstream water channel 2a of the water channel 2 so as to protrude toward the upstream water channel 2a. With the gate 1a closed, the pump 6 directs the water in the upstream water channel 2a of the gate 1a toward the pressure regulating water tank 3a provided on the drainage gate or the inflow side of the drainage pipe 3 on the downstream water channel 2b side. It performs the function of forced drainage. In the drawing, for example, two pumps 6 are attached to the left and right sides of the lower part of the gate 1a. For example, an axial pump is used as the pump 6.

  The pump 6 is attached to the gate 1a by the method shown in FIG. 1, for example. For example, in the case shown in FIG. 1, the peripheral edge side of the rear end of the water conduit 6a is integrally attached to a hole (not shown) formed in the pump mounting plate 1d attached to the surface of the gate 1a by a bolt or the like.

  An opening / closing door 7 is attached to the rear end side of the water conduit 6 a of the pump 6. For example, a flap gate is used for the open / close door 7. For example, the open / close door 7 made of a flap gate is provided on the inflow side of the drainage gate or drainage drainage pipe 3 on the downstream side water channel 2b side back to the back side of the pump mounting plate 1d on which the pump 6 is attached. It is attached toward the pressure-regulating water tank 3a side. For example, the open / close door 7 formed of a flap gate faces the pressure-regulating water tank 3a through an opening formed in the skin plate of the gate 1a.

  The open / close door 7 is directed toward the pressure regulating water tank 3a provided on the drainage gate or the inflow side of the drainage pipe 3 on the downstream water channel 2b side of the discharge pipe 7a attached to the back surface side of the pump mounting plate 1d. It is attached to the front end side surface that can be opened and closed. For example, the open / close door 7 formed of a flap gate is connected by a hinge structure 7b to the back side of the pump mounting plate 1d above the discharge pipe 7a whose upper end faces the pressure regulating water tank 3a.

  For example, the open / close door 7 formed of a flap gate has a pressure regulating water tank 3 a side provided on the inflow side of the drainage gate or drainage pipe 3 on the downstream water channel 2 b side of the gate 1 a with the hinge structure 7 b at the upper end as the rotation center. It has a so-called check valve structure that opens toward the top and closes toward the upstream water channel 2a of the gate 1a. The open / close door 7 is closed when the water pressure of the pressure regulating water tank 3a is high to prevent a reverse flow from the pressure regulating water tank 3a, and is opened by the water pressure of the discharged waste water from the pump 6 during forced drainage by driving the pump 6. The upstream water channel 2a can be drained to the pressure regulating water tank 3a side.

  The discharge pipe 7a and the open / close door 7 in a closed state are accommodated in a space between the pump mounting plate 1d and the skin plate on the inner side of the gate 1a, that is, the thickness side of the gate 1a. The discharge pipe 7a attached to the inner side of the gate 1a and the open / close door 7 in a closed state are accommodated within the thickness of the gate 1a that moves up and down. There is no hindrance to lifting.

  The management bridge 8 is a passage used when managing the pumped gate 1 and is installed across the water channel 2 between the upper part of the upstream water channel 2a of the pumped gate 1. The management bridge 8 is composed of a metal square planar floor 8a and a safety handrail 8b provided at the side edge of the width side of the floor 8a.

  In the management bridge 8 installed in the transverse direction in the upstream water channel 2a, one side in the width direction of the floor 8a, that is, the side on which the handrail 8b is attached is from the suction port 6b of the water conduit 6a of the pump 6 below. Is further extended to the upstream water channel 2a side. The other side in the width direction of the floor 8a extends to the vicinity of the front of the gate 1a of the upstream water channel 2a, but there is a gap between the front of the gate 1a and the floor 8a contacts the gate 1a that moves up and down. It is installed so as not to.

  The downstream side portion of the floor 8a of the management bridge 8 that is on the ascending / descending path of the water conduit 6a of the pump 6 is the floor of the management bridge 8 when the natural drainage is performed or when the gate 1a is pulled up when the pump 6 is inspected. The board 8a opens upward so as not to get in the way, and has a structure that does not hinder the passage of the water conduit 6a of the pump 6 that rises integrally with the gate 1a.

  That is, for example, a metal opening / closing lid 8c is partly attached to the downstream side portion of the floor 8a of the management bridge 8 that is directly above the pump 6. The open / close lid 8c is attached to both sides of the center of the water channel 2, and the open / close lids 8c attached to both sides of the open / close lid 8c are connected to the floor 8a by a hinge structure, for example. It is structured to open and open upward as the center of rotation.

  When pulling up the gate 1 with the pump by inspection or the like, the path of the water conduit 6a of the pump 6 that rises integrally with the gate 1a by opening the opening / closing lid 8c of the floor base 8a of the management bridge 8 in advance. To avoid getting in the way. Since the pump 6 pulled up on the floor 8a of the management bridge 8 is located on the management bridge 8, the operator can easily check the pump 6 using the management bridge 8 without making a separate scaffold. Can be performed.

  A gap is formed between the side edge of the floor 8a and the outer surface of the pressure-regulating water tank 3a where the gate 1a is installed so that the side edge of the floor 8a of the management bridge 8 does not contact the gate 1. Since there is a danger of falling from this gap sometimes, a safety cover 8d that opens upward is attached to this gap portion to ensure safety.

Next, the operation based on the configuration of the best mode for carrying out the invention will be described below.
When the gate 1a is raised for inspection of the pump 6 or natural drainage, the cylinder 5b of the gate lifting mechanism 5 is extended upward. When the piston rod of the cylinder 5b extends upward, the sheave 5d attached to the tip of the cylinder 5b also moves upward. The intermediate side of the wire rope 5a is wound around the upper half side of the sheave 5d that moves upward. For this reason, the sheave 5d moving upward pushes up the intermediate side of the wire rope 5a upward.

  At this time, since the other end of the wire rope 5a is connected and fixed to a fixing tool 5e below the side column 4 that does not move, when the intermediate side of the wire rope 5a is pushed upward, the wire rope follows this. One end side of 5a moves upward, and the gate 1 with pump to which this one end side is connected is pulled up by one end side of the wire rope 5a that moves upward.

  Since the sheave 5d pushes up the intermediate side of the wire rope 5a that is inverted upward, the pumped gate 1 to which one end of the wire rope 5a is connected rises at a speed twice the extension speed of the piston rod of the cylinder 5b.

  When the gate 1a is lifted, if it is desired to lift the gate 6a to the upper side of the floor 8a of the management bridge 8 for inspection of the pump 6, the pump 6 attached to the rising gate 1a The opening / closing lid 8c located on the ascending / descending path of the pump 6 is opened in advance so as not to hit the floor 8a. Similarly, the safety cover 8d attached just above the gate 1a is also opened.

  The pump 6 attached to the rising gate 1a can move to the upper side of the floor 8a from the opening of the floor 8a of the management bridge 8 with the opening / closing lid 8c opened without hitting the floor 8a. Then, the pump 6 moved to the upper side of the floor board 8a is inspected using the management bridge 8.

  When the gate 1a that has been raised is lowered, the piston rod that the cylinder 5b has extended is contracted. When the piston rod contracts downward, the sheave 5d moves downward, and when the sheave 5d moves downward, the weight of the gate 1 with the pump acts on one end of the wire rope 5a on the intermediate side of the wire rope 5a. Therefore, it goes down together with the sheave 5d.

  At this time, since the other end of the wire rope 5a is connected and fixed to a fixing tool 5e below the side column 4 that does not move, when the intermediate side of the wire rope 5a falls downward, the wire rope 5a follows this. The gate 1 with a pump to which this one end side is connected is pulled down by one end side of the wire rope 5a that moves downward. The pumped gate 1 is lowered by its own weight due to the weight of the gate 1a and the pump 6, and the water channel 2 is fully closed.

  Since the sheave 5d pushes and supports the intermediate side of the wire rope 5a that is inverted upward, the gate 1 with a pump to which one end of the wire rope 5a is connected descends at a speed that is twice the extension speed of the piston rod of the cylinder 5b. .

When the opening / closing lid 8c of the floor 8a of the management bridge 8 is opened for inspection of the pump 6, the opening / closing lid 8c opened after the gate 1a is lowered is closed. Similarly, the opened safety cover 8d is closed.

[Best Mode-2]
Here, FIG. 5 is a side sectional view of the gate equipment with a pump, and FIG. 6 is a left half side view of FIG. 5 A and a right half side of FIG.

  In the figure, the gate 11 with a pump is used for the downstream side of the upstream side water channel 12a provided outside the pressure regulating water tank 13a provided in the drainage sluice gate or the drainage culvert pipe 13 constituting a part of the drainage channel. It is forcibly discharged to the pressure regulating water tank 13a provided on the inflow side of the drainage lock or drainage pipe 13 on the side waterway 12b side, and has a structure in which the pump 16 is attached to the gate 11a. The water channel 12 is installed in the transverse direction. The gate with pump 11 has a structure that opens and closes the water channel 12 by raising and lowering a gate 11a as a door body. The drainage lock or drainage pipe 13 is a culvert structure provided across the river bank, and the drainage pit is a small culvert compared to the drainage lock.

  The gate 11 with a pump raises the gate 11a for natural drainage, and drains water for forced drainage, and uses the pump 16 attached to the gate 11a with the gate 11a closed for forced drainage. Is forcibly drained to the pressure regulating water tank 13a provided on the inflow side of the drainage drainage gate or drainage drainage pipe 13 serving as the downstream water channel 12b.

  The gate 11a includes a rectangular and plate-shaped skin plate, vertical and horizontal reinforcing girders attached to the surface of the skin plate facing the upstream water channel 12a, and the like. The skin plate of the gate 11a is reinforced by these reinforcing girders to increase the rigidity.

  The gate 11 with a pump is installed in a pressure-regulating water tank 13a provided on the inflow side of the drainage gate or drainage drainage pipe 13 so as to be movable up and down. For this reason, it is not necessary to construct a gate pillar structure outside the pressure regulating water tank 13a as in the prior art, and the construction cost is greatly reduced. In addition, until now, when removing the gate 11 with a pump using clay, etc., the height of the gate post is assumed to be crane work or other equipment is used so that the ceiling wall of the gate post structure is not hindered. However, since the frame 15e to which the gate lifting / lowering mechanism 15 directly above the pumped gate 11 is attached can be removed together with the gate lifting / lowering mechanism 15, the clay can be used, and the removal work of the pumped gate 11 can be efficiently performed. Can be performed.

  Guides for raising and lowering the left and right side ends of the pumped gate 11 on the left and right side walls on the upstream side inside the pressure regulating water tank 13a in which the pumped gate 11 is installed and the lower side water channel side walls connected thereto. Grooves 12c are formed in the vertical direction. The gate 11a is structured to move up and down along the guide groove 12c. Rollers 11b around the horizontal axis parallel to the transverse direction of the water channel 12 that reduce sliding resistance with the guide groove 12c are provided at the left and right ends of the gate 11a, respectively, and guide when the gate 11a moves up and down. It can be smoothly moved up and down along the groove 12c.

  Gate raising / lowering mechanisms 15 for raising and lowering the pumped gate 11 are provided on both sides outside the pressure regulating water tank 13a. The gate elevating mechanism 15 includes a rack type elevator 15b that meshes with a rack girder 15a that extends upward on both sides of the upper end of the pumped gate 11 and moves the pumped gate 11 up and down.

  The rack type elevators 15b are respectively installed on both sides outside the pressure regulating water tank 13a. The rack type elevator 15b is provided with a rotating pinion that meshes with the rack beam 15a. A handle 15c for rotating the pinion is attached to the rack type elevator 15b. The left and right rack type elevators 15b are interlocked and connected by an interlocking shaft 15d. When the handle 15c is turned, the pinions of the left and right rack type elevators 15b rotate around the same direction at the same speed.

  When the pinion is rotated in a certain direction by the handle 15c, the rack girder 15a meshing with the pinion moves upward, and the lower end side of the rack girder 15a moving upward is connected to the upper end of the gate 11 with the pump. It is a mechanism for pulling up the pumped gate 11 to which the sides are connected.

  Further, when the pinion is rotated in the direction opposite to the above by the handle 15c, the rack girder 15a meshing with the pinion moves downward, and the lower end side of the rack girder 15a moving downward is connected to the upper end of the gate 11 with pump. Thus, a mechanism is provided for pulling down the pumped gate 11 to which the lower end side is connected.

  A connector 11c to which the lower end side of the rack beam 15a for raising and lowering the gate 11a is connected is attached to the upper end of the gate 11a. For example, two connecting tools 11c are attached to the left and right sides of the upper end.

  The surface of the pump mounting portion below the gate 11a on the side facing the upstream water channel 12a of the water channel 12 is opened, and the tip of the pump 16 protrudes from the surface of the gate 11a to the upstream water channel 12a in this opened interior. It is installed in a state that does not. The pump 16 is mounted substantially horizontally to the vertical gate 11a in a state of protruding toward the pressure adjusting water tank 13a provided on the inflow side of the drainage lock or the drainage pipe 13 on the downstream water channel 12b side. ing. The pump 16 functions to forcibly drain the water in the upstream water channel 12a of the gate 11a toward the pressure-regulating water tank 13a with the gate 11a closed. In the drawing, for example, two pumps 16 are attached to the left and right sides of the lower part of the gate 11a. For example, an axial pump is used as the pump 16.

  The pump 16 is attached to the gate 11a by a method as shown in FIG. 6, for example. In this way, the water conduit 16a of the pump 16 faces the pressure regulating water tank 13a provided on the drainage gate or the inflow side of the drainage pipe 13 on the downstream water channel 12b side of the gate 11a via the pump mounting plate 11d. Attached to the surface.

  An open / close door 17 is attached to the rear end side of the water conduit 16 a of the pump 16. For example, a flap gate is used for the open / close door 17. For example, the open / close door 17 formed of a flap gate is attached toward the pressure regulating water tank 13a provided on the inflow side of the drainage gate or the drainage pipe 13 on the downstream side water channel 12b side.

  The open / close door 17 is directed toward the drainage lock or the pressure regulating water tank 13a provided on the inflow side of the drainage pipe 13 on the downstream water channel 12b side of the discharge pipe 17a attached to the rear end side of the water conduit 16a. It is attached to the front end side surface that can be opened and closed. For example, the open / close door 17 formed of a flap gate is connected to an upper portion of a flange that joins the rear end of the water conduit 16a facing the pressure-regulating water tank 13a and the discharge pipe 17a with a hinge structure 17b.

  For example, the open / close door 17 formed of a flap gate has a pressure regulating water tank 13 a side provided on the inflow side of the drainage gate or the drainage pipe 13 on the downstream water channel 12 b side of the gate 11 a with the hinge structure 17 b at the upper end as the rotation center. It has a so-called check valve structure that opens toward the top and closes toward the upstream water channel 12a of the gate 11a. The open / close door 17 is closed when the water pressure on the pressure regulating water tank 13a side is high to prevent a back flow from the downstream water channel 12b, and is opened by the water pressure of the discharged waste water from the pump 16 during forced drainage by driving the pump 16. The water in the upstream water channel 12a of 11a can be drained to the pressure regulating water tank 13a side.

  The management bridge 18 is a passage used when managing the pumped gate 11, and a pressure regulating water tank provided on the inflow side of the drainage gate or the drainage pipe 13 on the downstream water channel 12 b side of the pumped gate 11. It is installed across the water channel 12 between the upper parts of the inside of 13a. Moreover, the management bridge 18 is installed across the water channel 12 between the upper part of the upstream water channel 12a outside the pressure regulation water tank 13a.

  The management bridge 18 installed inside the pressure-regulating water tank 13a is made of a metal square planar floor board 18a, and the management bridge 18 installed outside the pressure-regulating water tank 13a includes the floor board 18a and the floor board 18a. It is comprised from the handrail 18b for safety provided in the side edge of the width one side.

  The management bridge 18 installed in the transverse direction inside the pressure regulating water tank 13a is in contact with the inner wall on the downstream side of the pressure regulating water tank 13a on one side in the width direction of the floor board 18a. The other side of the floor 18a in the width direction extends to the vicinity of the upstream gate 11a. However, there is a gap between the gate 11a and the floor 18a is installed so as not to come into contact with the rising and lowering gate 11a. ing.

  The upstream side portion of the floor 18a of the management bridge 18 on the ascending / descending path of the water conduit 16a of the pump 16 is the floor of the management bridge 18 when natural drainage is performed or when the gate 11a is pulled up when the pump 16 is inspected. The board 18a opens upward so as not to get in the way, and has a structure that does not hinder the passage of the water conduit 16a of the pump 16 that rises integrally with the gate 11a.

  That is, for example, a metal opening / closing lid 18c is partially attached to the upstream side portion of the floor 18a of the management bridge 18 that is directly above the pump 16. The open / close lid 18c is attached to both sides of the center of the water channel 12, and the open / close lid 18c attached to both sides of the open / close lid 18c is connected to the floor 18a by a hinge structure at the width end of the water channel 12, for example. It is structured to open and open upward as the center of rotation.

  When pulling up the gate 11 with the pump by inspection or the like, the path of the water conduit 16a of the pump 16 that rises integrally with the gate 11a by opening the opening / closing lid 18c of the floor 18a of the management bridge 18 in advance. To avoid getting in the way. Since the pump 16 pulled up on the floor 18a of the management bridge 18 is located on the management bridge 18, the operator can easily check the pump 16 using the management bridge 18 without making a separate scaffold. Can be performed.

  A gap is formed between the side edge of the floor 18a and the external surface of the pressure regulating water tank 13a where the gate 11a is installed so that the side edge of the floor 18a of the management bridge 18 does not contact the gate 11. Since there is a risk of falling from this gap at times, a safety cover (not shown) that opens upward is attached to the gap as necessary.

Next, the operation based on the configuration of the best mode for carrying out the invention will be described below.
When the gate 11a is raised for inspection of the pump 16 or natural drainage, the handle 15c of the rack type elevator 15b of the gate lifting mechanism 15 is turned in a certain direction to move the rack girder 15a upward. When the handle 15c is rotated in a certain direction, the left and right rack type elevators 15b interlocked and connected by the interlocking shaft 15d rotate the pinions engaged with the rack beam 15a around the same direction at the same speed.

  When the pinions of the left and right rack type elevators 15b are rotated in a certain direction by the handle 15c, the left and right rack girders 15a meshing with the pinions of the left and right rack type elevators 15b move upward, and the lower end side of the rack girder 15a moving upward is By being connected to the upper end of the gate 11 with pump, the gate 11 with pump to which this lower end side is connected is pulled up.

  When the gate 11a is lifted, if it is desired to lift the gate 16a to the upper side of the floor 18a of the management bridge 18 for inspection of the pump 16, the pump 16 attached to the rising gate 11a is connected to the management bridge 18 just above it. The opening / closing lid 18c located on the ascending / descending path of the pump 16 is opened in advance so as not to hit the floor 18a. In addition, the safety cover attached as necessary directly above the gate 11a is also opened.

  The pump 16 attached to the rising gate 11a can move to the upper side of the floor 18a from the opening of the floor 18a of the management bridge 18 in which the opening / closing lid 18c is opened without hitting the floor 18a. The pump 16 moved to the upper side of the floor board 18a is inspected using the management bridge 18.

  When lowering the gate 11a that has been raised, the handle 15c of the rack type elevator 15b of the gate lifting mechanism 15 is turned in the opposite direction to move the rack girder 15a downward. When the handle 15c is rotated in the reverse direction, the left and right rack type elevators 15b interlocked and connected by the interlocking shaft 15d rotate the pinions that mesh with the rack beam 15a around the same reverse direction at the same speed.

  When the pinions of the left and right rack type elevators 15b are rotated in the reverse direction by the handle 15c, the left and right rack girders 15a meshing with the pinions of the left and right rack type elevators 15b move downward, and the lower end side of the rack girder 15a moving downward is By being connected to the upper end of the gate 11 with pump, the gate 11 with pump to which this lower end side is connected is pulled down.

  When the opening / closing lid 18c of the floor 18a of the management bridge 18 is opened for inspection of the pump 16, the opening / closing lid 18c opened after the gate 11a is lowered is closed. Similarly, the safety cover provided as needed is closed.

  Note that the present invention is not limited to the best mode for carrying out the invention, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described best mode-1, the case where the wire rope 5a is used for the gate elevating mechanism 5 has been described, but a belt-like belt may be used instead. Alternatively, the cylinder 5b and the pumped gate 1 may be directly connected without using the wire rope 5a. Further, in the above best mode-2, the gate elevating mechanism 15 is a rack type elevator 15b that meshes with the rack girder 15a extending upward on both sides of the upper end of the pumped gate 11 and moves the pumped gate 11 up and down. Although explained in the case of being configured, the present invention is not limited to this, and the gate with pump is explained through the wire rope 5a which is extended upward and connected to the gate 1 with pump as explained in the best mode-1. 1 may be composed of a cylinder 5b that moves up and down. In this case, the cylinder 5b is similarly installed at the place where the rack type elevator 5b is installed.
