  Hereinafter, a first embodiment of a placing device such as a mortar according to the present invention will be described in detail with reference to the drawings. First, a waterway constituent member for using a placing device such as a mortar of the present embodiment and a waterway construction method will be described with reference to FIGS. FIG. 1: shows the water channel structure member which comprises the novel water channel for implementing the water channel structure construction method of this embodiment, (a) is a front view, (b) is a side view which shows a connection state, FIG. It is a perspective view which shows a state.

  1 and 2, the water channel component 1 is basically shaped like a cylinder divided in half along the axial direction, and has a bowl-like shape that forms a water channel that opens upward and flows sewage and the like. An invert unit 2 is provided. For example, the invert section 2 is formed in a substantially semicircular arc shape with a radius of about 100 to 150 mm, and has a bowl shape with a length of about 0.5 to 1 m. Joining flange portions 3 and 3 extending at a right angle toward the outside are formed at both ends of the waterway constituent member 1 in the waterway direction, and a plurality of connecting holes 4 are formed at predetermined intervals. The water channel component 1 includes inclined portions 5 and 5 that continue upward ascending from the upper end of the invert portion 2 and the gradient of the inclined portions 5 and 5 is preferably about 20%.

  The waterway component 1 is integrally formed of reinforced plastic (FRP) reinforced with glass fiber or the like, but is not limited to FRP, and is not a reinforced normal plastic molded product, metal casting, or sheet metal processed product. For example, an angle material or the like may be embedded in a corner portion between the invert portion 2 and the inclined portions 5 and 5 for reinforcement. In addition, although the length of the water channel direction in which the sewage etc. of the water channel component 1 flows is formed to about 50 cm, it is not limited to this length, and can be set to any length according to the size of the manhole that can be inserted. Can be set.

  The above-described waterway constituent member 1 can be connected to a predetermined number in the direction of connecting the waterways to form a waterway. That is, it is necessary in the direction of the water channel by connecting the joint flange portions 3 and 3 of the water channel component members 1 and 1 and fastening the connecting hole 4 with a bolt nut or a long bolt and a fastening member 6 such as two nuts (FIG. 1b). It is possible to form a new water channel in the pipe line by connecting only a certain length. Further, as described above, the connecting flange portions can be connected in contact with each other, and the connecting flange portions 3 and 3 can be connected with a spacer 7 described later interposed therebetween.

  The spacer 7 includes a contact portion 7a having the same shape as the joint flange portion 3 and a leg portion 7b extending downward from the contact portion. The joint portion 4a has a connecting hole 4 in the joint flange portion. A through hole is formed at the same position, and a fold line for cutting is formed at the leg portion 7b. The height of the spacer 7 can be changed by cutting along a broken line, and the spacer 7 functions as a gradient imparting member that imparts a gradient to the connected waterway component 1. The new water channel formed in this way can form a water channel with an arbitrary slope set in a pipe whose slope has changed due to uneven settlement or the like.

  Next, for example, a water channel construction method for forming a new water channel in the existing pipe P using the water channel component 1 will be described with reference to FIGS. FIG. 3 is a cross-sectional view of a state in which the waterway constituent member is installed in the pipe, FIG. 4 is a cross-sectional view in the longitudinal direction thereof, and FIG. 5 is a cross-sectional view showing an example process of the waterway constitution method. 3-5, first, the above-mentioned waterway constituent member 1 is carried into the pipe P from the manhole, and the joining flange portions 3, 3 of the waterway constituent members 1, 1 to be connected are opposed to each other. The fastening member 6 such as a bolt and nut is fastened and connected through the connecting hole 4 and the through hole with the spacer 7 interposed between the two members.

  When connecting the waterway component 1, the height of the leg portion of the spacer 7 is cut and set in accordance with the slope of the pipe line P measured in advance. Then, the spacer 7 having a set height is sandwiched between the joining flange portions 3 and 3 and fastened with a fastening member 6 such as a bolt and nut. This operation is repeated, and a length corresponding to, for example, a pipe line between two manholes. The water channel constituent member is inserted into the pipe P and connected. In this way, the invert part 2 of the waterway constituent members 1... Connected and installed becomes a new waterway with an appropriate gradient.

  In the above process, when a new water channel is formed in the pipe P, the hose 8 is placed on the water channel as a liquid container (FIG. 5a). This hose is soft and preferably flattened and flat when no liquid 9 is contained therein. Such a hose can be wound up in a crushed state, and is also suitable for conveyance and loading from a manhole into a pipeline. Further, the diameter of the hose is preferably substantially equal to the width of the invert portion 2, and the length of the hose is preferably longer than the length of the connected waterway constituent member. When one end of the hose placed (preferably downstream side) is closed and water 9 is injected as a liquid from the other end side (FIG. 5b), the hose is filled with water and becomes cylindrical, so the other end The side also occludes. In the case of a soft hose, the end of the hose may be closed by being tied with a rope or the like, or may be closed with a cap-shaped lid.

  When the water 9 is filled in the hose 8, the hose has a circular cross section and is in close contact with the invert portion 2, and the water channel components 1... Connected by its weight are pressed toward the bottom surface of the pipe P, and the next step Since the mortar is prevented from being lifted by buoyancy during placement, it is stably installed, so that the water channel constituent members 1 in the next step can be smoothly fixed to the pipeline. In this fixing step, a filler such as mortar M is placed in the space on both sides in the direction intersecting the water channel direction of the water channel component member with the water channel component members 1 pressed downward. Placing the mortar M is preferably performed in two steps, for example. After the first mortar is placed, it is preferably left to cure for about half a day, and then the second mortar is placed the next day. is there. In addition, although the example using the pressing force due to the weight of the liquid in the hose was shown as a means to prevent the waterway constituent member from floating when mortar is placed, a restraining tree or the like is inserted between the waterway constituent member and the upper surface of the pipe Thus, lifting may be prevented, and an appropriate means can be used.

  The first mortar placement is performed with an amount of injection that is about the half of the total amount injected (FIG. 5c). When the mortar M1 placed for the first time is cured, the lower part of the spacer 7 is firmly fixed to the bottom surface of the pipe P, and the movement of the water channel components 1 is prevented, so that the second mortar placement is easy. Can be done. In this way, after the mortar M1 is placed between the waterway constituent members 1... And the pipe P and fixed to the pipe, the filled water is discharged when the closed portion on the downstream side of the hose 8 is opened. The hose 8 is crushed and flattened, and is wound up and removed. The hose 8 is wound to have a small diameter and is light in weight so that it can be easily removed. In other words, since the downwardly connected waterway constituent members can be easily pressed and the equipment used for the pressing can be easily removed, the fixing operation of the waterway constituent members can be completed in a short time.

  The second placement is performed up to the inclined portions 5 and 5 of the water channel components 1... And the upper surface of the mortar M2 is finished with a smoothing plate or the like on the inclined surface Ma in accordance with the gradient of the inclined portion (FIG. 5d). As described above, when the mortar placing operation is performed in two steps, the ironing operation can be efficiently performed and the workability is improved. The mortar placement may be completed once, and is particularly suitable when the pipe has a small diameter. The new water channel formed by connecting and installing the water channel components through the above steps is compatible with the fact that the gradient is maintained properly even when the gradient of the existing pipeline is not appropriate, and the cross-sectional area of the water channel is reduced. Thus, the flow rate of sewage and the like can be secured, and the sewage and the like can smoothly flow down.

  As described above, after the plurality of waterway constituent members 1 are connected and installed in the pipe P, a predetermined gradient is given, and a filler such as mortar M is provided in the space between the pipe P and the waterway constituent members 1. Is injected and fixed. In this embodiment, when connecting the waterway constituent members 1..., The spacers 7 are sandwiched and fixed in a watertight state, and the height of the spacers 7 is adjusted to provide a gradient. Thereby, even when the gradient is reversed due to, for example, non-settlement in the existing pipeline P, a water channel having an appropriate gradient can be formed by the invert portions 2 of the water channel components 1. It should be noted that in the above-described process, the water channel constituent member that is connected and installed at the time of mortar placement is pressed downward to prevent the water channel constituent member from being lifted. It may be fixed by, for example, to prevent floating.

Move. By this movement, the leveling plate portions 53, 53 are rough-finished into an inclined surface that scrapes the upper surface of the mortar and extends to the inclined portion. This first leveling device D3 is basically towed and moved together with the second placement device D2, and can smooth the top surface of the mortar after placement of the mortar by a single movement. . In FIG. 14 a, the leveling plate portion 53 and the inclined portion 5 are opposed to each other with a gap, but at the time of leveling work, they move in contact with each other to form a mortar surface Ma that extends to the inclined portion 5. . The mortar dropped on the invert part 2 during the leveling work is scraped out by the removal plate 57.

  The first placing device D1 or the second placing device D2 described above and the first leveling device D3 may be integrally configured. For example, the base plate portion 31 of the second placing device D2 is extended rearward in the moving direction and also used as the main body portion of the first leveling device D3, and the upper surface of the mortar is leveled on the base plate portion 31. By fixing the leveling plate, it is possible to configure so that the mortar placement work and the mortar top surface can be done at once, making the mortar placement work in the waterway construction method more efficient. This can shorten the work time.

  Next, a modified example of the first leveling device D3 will be described with reference to FIG. The leveling device D3A shown in FIG. 16 protrudes from the leveling plate portions 53, 53 of the first leveling device D3 to the front side in the moving direction, and a filler such as mortar flows into the invert portion 2 of the water channel component 1 Inflow prevention plates 58 and 58 for preventing this are continuously provided in the leveling plate portion. The two inflow prevention plates are close to the upper surfaces of the inclined portions 5 and 5 of the water channel component 1 and may be brought into contact with each other via a rubber plate (not shown). The inflow prevention plates 58 and 58 are formed so as to spread downward as is apparent from the front view of FIG. 16a, and are spread in the moving direction (arrow A) as is clear from the plan view of FIG. 16b. It is formed as follows.

  For example, as shown in FIG. 17, the leveling device D3A is moved by being pulled by the second driving device D2 with the rope R1. When the mortar m1 is discharged by the second placing device, the mortar m1 is initially injected into the gap between the water channel component 1 and the pipe P, and as the injection proceeds, filling gradually proceeds from the lower side to the upper surfaces of the inclined portions 5 and 5. When discharged, the mortar m2 accumulates in a space surrounded by the leveling plates 53 and 53 and the inflow prevention plates 58 and 58. The mortar m2 accumulated up to the top of the inclined portions 5 and 5 is prevented from flowing into the invert portion 2 by the inflow preventing plates 58 and 58 with the movement of the second placing device D2, and the lower side is the rear side. Since the mortar m2 is leveled so as to be pressed by the leveling plate portions 53, 53 inclined in the direction, a uniform level surface can be obtained. Moreover, even if the discharge amount of the mortar discharged from the second placement device D2 is not constant on the left and right, the mortar is once averaged after being stored in the mortar reservoir (m2). The finished state of the surface Ma is constant.

  Next, a second leveling device D4 such as a mortar according to the present invention will be described with reference to FIGS. 18 to 20 are a front view, a plan view, and a side view, respectively, of the second leveling device D4. This leveling device D4 is basically composed of a main body 60 that moves on the waterway components 1 ..., and a leveling plate 70 that leveles the upper surface of the mortar placed on the outer peripheral side of the main body. 70. The two leveling plates are supported so as to be movable with respect to the main body 60, that is, swingable so as to spread outward, and are biased outward.

  The main body portion 60 is formed by welding steel materials in the same manner as in the above-described embodiment, and a rectangular portion is formed by two vertical members 61 and three cross members 62 positioned on the front side in the movement (arrow A) direction. Further, two inclined members 63 on the rear side, a cross member 64 on the rear end, and an intermediate member 65 are provided, and support plate members 66 and 66 are welded outward from the vertical members 61 and 61 on the front side. The second leveling device D4 moves the flat leveling plates 70, 70 in a plane direction on the mortar M, thereby finishing the mortar surface Ma flat. Note that the moving direction may be linearly slidable in addition to the axis that swings at a predetermined swing angle with respect to the shaft.

  Two rollers 67 and 67 are fixed to the lower surface of the two vertical members 61 of the main body 60 on the front side. Further, four guide pieces 68 that enter the invert portion 2 are fixed to the front cross member 62 and the rear cross member 64. These guide pieces 68 have a shape in which the front end portion is curved inward and is easy to move along the invert portion 2. The leveling plates 70, 70 are in contact with the inclined portions 5, 5 at their lower surfaces. The front end of the main body 60 is supported by two rollers 67, the two leveling plates 70 are in contact with each other at the rear, and the leveling plates 70, 70 are inclined along the water channel constituting member 1 by the guide pieces 68. It can be moved to slide.

  The leveling plates 70, 70 can swing around swinging shafts 71, 71 fixed to the support plate members 66, 66 of the main body 60, and the support shafts 72, 72 and the fixed shaft of the vertical member 61 are fixed. The tension springs 73 and 73 mounted therebetween are biased outward. The leveling plates 70, 70 are formed of flat plates and can swing along the inclination angle of the inclined portions 5, 5, and a forward inclined surface 70a for pressing the mortar is formed on the lower surface on the front side. Yes. A reinforcing thick portion 70b is formed on the upper surface of the leveling plate 70 along the outer periphery on the front side.

  The second leveling device D4 configured as described above can be finished by stroking the upper surface of the mortar roughened by the first leveling device D3 in the surface direction with the leveling plates 70, 70. The top surface of the mortar M can be a smooth inclined surface Ma. Further, since the leveling plates 70 and 70 can swing according to the diameter of the pipe P, the surface can be finished according to the placement width of the mortar M. The leveling plates 70, 70 are both swung inward, whereby the tension springs 73, 73 are positioned on the rocking shafts 71, 71 and can be held in elastic contact with each other. can do.

  The placement device of the present invention can be configured by connecting the first leveling device D3 for roughening to the second placement device D2. In addition, both the first leveling device D3 and the second leveling device D4 can be connected to the second placing device D2. For example, as shown in FIG. 21, when both the rough leveling device D3 and the finish leveling device D4 are connected to the second placing device D2, the first mortar placement is performed by the first placing device D1. The second mortar placement with the second placement device D2 of FIG. 21 is performed with the discharge pipe 43 of the piping section 40, and the roughening of the upper surface of the placed mortar is performed with the first leveling device D3. The mortar that has fallen to the invert section 2 is removed by the removal plate 57, and the finish leveling can be simultaneously performed by the leveling plate 70 of the second leveling device D4. It is suitable for installation. As the connecting means, ropes R1, R2 and chains can be used, and they may be connected using a connecting tool such as a shackle. Further, the second driving device D2 is configured to include a self-propelled drive mechanism, and the first leveling device D3 for roughening and the second leveling device D4 for finishing leveling are pulled. You may comprise as follows.

  In the above-described embodiment, an example in which the height of the spacer 7 sandwiched between the waterway constituent members is changed as means for imparting a gradient to the waterway constituent members 1... Is shown in FIGS. As in the member 1 </ b> A, a water channel component member having a plurality of leg portions 80 may be used to change the length D of each leg portion 80 to give a gradient. This waterway component 1A is provided with at least one or more leg portions 80, and is provided with a gradient by changing the length D of each leg portion 80. In this water channel component 1A, as shown in FIG. 22b, the joining flange portion 3 is connected by the fastening member 6, the lower end sphere is brought into contact with the inner surface of the pipe, and the length D of the two leg portions 80 (see FIG. 22a). ) To adjust the overall height and slope.

  Needless to say, the means for imparting the gradient is not limited to the above-described configuration. For example, the water channel components 1... Are inserted into the pipeline P along a gradient rail (not shown). Can be fixed. Further, the leg portion 80 of the water channel component member 1A is not limited to two, and may be configured to have, for example, four leg portions, and may include a water channel component member having four leg portions and a leg portion. It is also possible to connect the non-waterway constituent members alternately and adjust the lengths of the four legs located alternately to set the gradient.

  22 and 23, the water channel component 1A will be described in detail. 1 A of waterway structural members are provided with the bowl-shaped invert part 2 which comprises the waterway which opens upwards and a sewage etc. flow through like the above-mentioned waterway structural member 1, and is right-angled outward toward the both ends of a waterway direction. Are formed with a plurality of connecting holes 4 at predetermined intervals. This waterway component 1A is also inverted by bringing the joint flange portion 3 into contact with the joint flange portion 3 of the other waterway member 1A, inserting a bolt into the connection hole 4 as a fastening member 6, and tightening with a nut. The parts 2 can be connected so as to extend. The water channel component 1A is provided with inclined portions 5 and 5 that continue upward ascending outward from the upper end of the invert portion 2, and the outer peripheral ends of the inclined portions are extended upward to rise up portions 5a and 5a. Is formed. The gradient of the inclined portions 5 and 5 is preferably about 20%, and the rising portions 5a and 5a are extended in the vertical direction. The rising part 5a continuing from the inclined part 5 is not necessarily required.

  For example, when the water channel constituent member 1A is installed in an existing pipe-shaped pipe P, at least one or more stretchable members whose lower ends abut on the inner surface of the pipe P are supported to support the water channel constituent member 1A. Legs 80 are provided. That is, two attachment plate portions 5b are fixed to the lower surfaces of the inclined portions 5 and 5 in the vicinity of the joint flange portion 3 on one side, and the attachment plate portion 5b is bent in the horizontal direction at the intermediate portion. A leg portion 80 is fixed in the vertical direction to the extending end portion of the plate portion 5b in the horizontal direction. For this reason, each of the two leg portions 80 can be expanded and contracted in the vertical direction in a parallel state, and two points are in contact with the pipe line. The reason why the mounting plate portion 5b is separated from the joining flange portion 3 is to facilitate the connection with the fastening member 6 such as a bolt and nut when connecting the water channel component 1A.

  The leg portion 80 is formed in a double structure from an outer peripheral fixed pipe portion 81 and an inner peripheral central shaft portion 82, and the outer peripheral thread portion of the central shaft portion 82 is screwed into the inner peripheral thread portion of the fixed pipe portion 81. ing. The outer periphery of the fixed pipe portion 81 is a hexagonal column, and is screwed to the mounting plate portion 5b with a screw portion 81a (see FIG. 23) whose upper end is reduced in diameter. The central shaft portion 82 on the inner periphery is formed with a screw on the outer periphery over the entire length of the shaft, a hexagonal hole 83 (see FIG. 23) into which the hexagonal bar spanner S can be fitted is formed on the upper end, and a screw hole is formed on the lower end. A sphere 84 is screwed. Therefore, by rotating the hexagonal bar spanner S fitted in the hexagonal hole 83, the central shaft part 82 moves up and down with respect to the fixed pipe part 81, and its vertical length D can be continuously changed. . The leg portion 80 of the present embodiment has a double structure of a fixed pipe portion 81 and a central shaft portion 82 having the same length, and the contracted state can be made relatively small, and from the contracted state to the maximum extended state. There is an advantage that a large adjustment range can be taken.

  Further, due to the sphere 84 fixed to the lower end of the leg portion 80, the end portion of the leg portion that comes into contact with the inner surface of the pipe line is a spherical surface, and the leg portion 80 comes into contact with the inner wall of the pipe line P by this spherical surface. It is configured as follows. Thus, since the spherical surface is in point contact with the inner wall surface of the pipe P, when the central shaft portion 82 of the leg portion 80 is continuously rotated, the water channel constituent member 1A can be moved up and down continuously. It is possible to prevent the water channel constituent member 1A from rising or falling rapidly during up and down movement. Since the sphere 84 of the leg 80 and the wall surface of the pipe P are in point contact, the insertion of the water channel component 1A into the pipe P can be easily performed with low resistance. The lower end of the central shaft portion 82 may be formed in a spherical shape without fixing the sphere to the lower end of the leg portion 80.

  The upper end of the leg portion 80 is exposed from the upper surface of the water channel component member 1A so that it can be adjusted after installation, and a hexagonal hole 83 that is an adjustment unit for adjusting the vertical position of the water channel component member is exposed. Adjustment operation is possible. For this reason, it is possible to adjust the length D by inserting the hexagon wrench spanner S from above into the hexagon hole 83 and rotating the central shaft portion 82. When the central shaft portion 82 is rotated clockwise and lowered, for example, the hexagonal hole 83 moves deep inside the fixed pipe portion 81, the hexagonal bar spanner S needs to be longer than the fixed pipe portion 81. . Moreover, although the above-mentioned leg part 80 is a double structure of the outer periphery fixed pipe part 81 and the center shaft part 82, although not shown in figure, the adjustment width | variety may be enlarged as a triple structure or a quadruple structure. it can.

  The leg portion 80 as the gradient imparting member shown in this embodiment is connected by adjusting the length D by rotating the hexagonal bar spanner S fitted in the hexagonal hole 83 exposed on the upper surface. In addition, the gradient of the waterway constituting member 1A can be easily set, and the gradient once set can be easily changed. Also in the case of the waterway component 1A... Connected to have a desired gradient in this way, a container such as a hose 8 that can store liquid is placed on the top, and the liquid 9 is filled in the hose 8. The leg 80 can be fixed with mortar or the like in a state where a pressing force directed downward is applied to the water channel component 1A, and the water channel component 1A is pressed against the pipe P. And after fixing, the hose 8 can be easily removed by discharging the liquid. Furthermore, in-service sewage can be used as the liquid.

  Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention described in the claims. Design changes can be made. For example, although the thing provided with the invert part, the joining flange part, and the inclination part was shown as a water channel component member, it may have a flat part which does not have an inclination part. Moreover, it does not have a joining flange part, and can use suitably what has a groove part for joining, press-fits, what joins by adhesion | attachment, etc.

  In the above-described embodiment, the second driving device is configured to pull the first leveling device that performs roughening and the second leveling device that performs finishing leveling. One of a first leveling device for roughing the first or second driving device and a second leveling device for finishing leveling. Or both leveling devices may be configured to be towed.
