  In addition, the water control body of the present invention is not particularly limited to the fluid valve 4 of the present embodiment, and may be anything that can be formed so as to be able to block, change, or switch the pipe line inside the existing pipe.

  Next, the water control body installation device of the present embodiment will be described based on the installation process.

  As shown in FIG. 1 and FIG. 2 (a), the joint rings 11 and 11 of the present embodiment are installed in the existing water pipe in the vicinity of the upstream side and the downstream side of the predetermined portion S where the existing water pipe 1 is cut as will be described later. Attached to the outer surface of the tube 1 along the circumferential direction.

  Further, the second seals 14 and 14 having elasticity formed in an endless shape by connecting both ends to the inner surfaces of the attached joint rings 11 and 11 are provided in the vicinity of the upstream side and the downstream side of the predetermined portion S. Attached to the outer surface of the existing water pipe 1 along the circumferential direction.

  Next, as shown in FIGS. 2B and 3, the joint ring 11 to which the predetermined portion S of the existing water pipe 1 and the second seal 14 attached to the existing water pipe 1 as described above are attached. A casing 10 formed so as to be able to surround the two is attached to the outer surface of the existing water pipe 1 in a watertight manner.

  The housing 10 has a vertically divided structure that can be removed by bolts and nuts 9 and connected in a watertight manner, and is formed on the facing side surface so as to have the same diameter as the outer diameter of the existing water pipe 1. The existing water pipe 1 is surrounded so that the side opening 10a and the peripheral surface of the existing water pipe 1 are aligned, and a packing 43 having water tightness is fitted between the side opening 10a and the existing water pipe 1 It is inserted and sealed with push wheels 41 and 42 having a divided structure.

  Moreover, the housing | casing 10 has the upper opening 10b of the planar view circular shape larger diameter than the outer diameter of the existing water pipe 1 in the upper part, and has the on-off valve 20 which can be opened and closed freely above the upper opening 10b. The hole saw cutter 30 of the existing water pipe 1, which will be described later, and the pipe piece 1a after cutting of the existing water pipe 1 enter and exit from the housing 10 through the upper opening 10b.

  Next, excision of the existing water pipe 1 will be described.

  As shown in FIG. 4, the hole saw cutter 30, which is an existing tube excision means of the present invention, includes a body 31 having an inner diameter substantially the same as the inner diameter of the upper opening 10 b, and a perforation that is accommodated in the inner space of the body 31. And a perforating machine 33 that can press the perforating cutter 32 toward a predetermined location S of the existing water pipe 1.

The center drill 32b is disposed in a position below the punching blade 32a and has a hollow cylindrical shape having a latch piece 32c provided at the tip of the center drill 32b.

  Next, the cutting process of the existing water pipe 1 will be described. The on-off valve 20 is closed, the central axis of the cylindrical piercing cutter 32 is substantially in the vertical direction, and the existing water pipe 1 in the housing 10 is closed. The body 31 is connected in a watertight manner above the on-off valve 20 so as to be disposed at a position substantially perpendicular to the central axis.

  Next, the piercing cutter 32 is moved by the piercing machine 33 in which the piercing blade 32a is moved forward and backward so as to pass through the entire cross section of the existing water pipe 1 while the on-off valve 20 is opened and the piercing cutter 32 is rotated. Move down. By rotating and lowering the drilling cutter 32, the existing water pipe 1 is gradually cut downward from the outer peripheral surface of the upper surface of the existing water pipe 1 at the two cut surfaces between the diameters of the bottom edge of the drilling cutter 32. The existing water pipe 1 is cut at the two cut surfaces at the point where the cutting blade 32a is lowered so as to pass through the entire cross section of the existing water pipe 1, and the pipe piece 1a is cut between the two cut surfaces. However, it is divided from the pipe line of the existing water pipe 1.

  In the cutting operation of the existing water pipe 1 described above, since the existing water pipe 1 is in an undisturbed water state, the existing water pipe 1 in the present embodiment is full of water, and in the cutting operation by the punching cutter 32, the center drill 32b When the fluid reaches the inside of the existing water pipe 1 from the outer peripheral surface of the upper surface of the existing water pipe 1, the fluid inside the existing water pipe 1 leaks out of the pipe, and the fuselage is connected to the inner space and the upper side of the housing 10. 31 will be filled. However, the fluid leaking from the inside of the existing water pipe 1 does not leak to the outside of the housing 10. Therefore, the cutting operation can be performed while the fluid in the existing water pipe 1 remains in an undisrupted water state.

  In addition, the chips generated when the existing water pipe 1 is cut can be discharged together with the fluid in the existing water pipe 1 through a discharge port 10c provided in a lower part in the vicinity of the predetermined location S of the housing 10 so as to be opened and closed. It has become.

  In addition, the step of carrying out from the inside of the housing 10 includes lifting the unloading material (the pipe piece 1a and the existing pipe cutting means) into the body 31, and then closing the on-off valve 20, thereby allowing the fluid in the existing water pipe 1 to be contained in the housing. The work can be carried out in an undisturbed state without leaking to the outside of the body 10.

  In addition, the existing pipe excision means in the present invention is not necessarily limited to the above-described configuration. For example, if the predetermined portion S of the existing pipe in the housing 10 is excised in a watertight manner, for example, the circumferential direction of the existing pipe The existing pipe may be cut by rotating the cutting means.

  Next, placement of the fluid valve 4 on the placement position will be described.

  As shown in FIGS. 5 and 6, guide pieces 50, 50 extending in the vertical direction are provided at two locations orthogonal to the tube axis C on the inner side surface of the housing 10, as will be described later. A pair of side end portions of the fluid valve 4 placed inside is provided so as to be sandwiched from both the upstream and downstream sides of the existing water pipe 1, and the fluid valve 4 is guided and placed at a predetermined location S. Is formed.

  Further, the separation distance at the upper part of the pair of guide pieces 50, 50 is formed wider than the separation distance at the lower part.

  Further, as shown in FIG. 8, a stopper 52 that specifies the placement position of the fluid valve 4 in the vertical direction is provided below the guide piece 50 on the inner surface of the housing 10.

  Next, the placement of the fluid valve 4 at the placement position in the housing 10 will be described. Insertion means (not shown) provided in the body that is watertightly connected to the upper opening 10 b of the housing 10. As a result, as shown in FIGS. 5 and 6, the fluid valve 4 is inserted into the mounting position from the upper side to the lower side inside the housing 10.

  Here, the placement of the fluid valve 4 in the placement position in the present invention means that the fluid valve 4 inserted into the housing 10 by the insertion means is guided to the guide piece 50 provided on the inner surface of the housing 10. However, it means a position (see fluid valve 4 ′ in FIGS. 7 and 8) placed at a predetermined location S in the casing 10, and a connection position of the fluid valve 4 described later (fluid in FIGS. 7 and 8). Different from valve 4).

  Further, laterally bulging guides 53, 53 are detachably attached to the fluid valve 4 main body by mounting bolts 54 on the left and right side surfaces of the fluid valve 4, and when the fluid valve 4 is inserted. Is inserted in a state in which the respective guides 53 and 53 are fitted between the guide pieces 50 and 50 provided in a pair so as to be sandwiched from both the upstream and downstream sides of the existing water pipe 1 as described above. . By doing in this way, when the fluid valve 4 is lowered toward the predetermined location S by the insertion means, the fluid valve 4 is guided by the guide piece 50 and placed at the predetermined location S. The operation of placing the fluid valve 4 is facilitated even under the influence of the flow or the like in 1.

  Further, as shown in FIGS. 5 and 6, the separation distance at the upper part of the pair of guide pieces 50 is formed wider than the separation distance at the lower part. In the initial stage of insertion of the fluid valve 4, the insertion operation is easy.

  Further, the separation distance at the lower part of the pair of guide pieces 50, 50 becomes narrow, and when the fluid valve 4 is lowered toward the predetermined position S by the insertion means, the fluid valve 4 is driven by the pair of guide pieces 50, 50. Therefore, the fluid valve 4 can be reliably placed without detaching from the predetermined location S.

  The guide pieces of the present invention do not necessarily have to be provided in pairs so as to be sandwiched from both the upstream and downstream sides of the existing water pipe 1 of the fluid valve 4 as long as they extend at least in the vertical direction on the inner surface of the housing 10. For example, the guide piece may be provided only on the downstream side of the existing water pipe 1 at two positions orthogonal to the pipe axis C on the inner side surface of the housing 10.

  In this case, the guide piece provided only on the downstream side of the fluid valve 4 placed in the housing 10 under the influence of fluid flowing from the upstream side of the existing water pipe 1 toward the downstream side. And is placed at the placement position while being guided.

  Furthermore, as long as the guide piece of the present invention extends at least in the vertical direction on the inner surface of the housing 10, the separation distance at the upper part of the guide piece does not necessarily have to be formed wider than the separation distance at the lower part. For example, the guide piece may be formed substantially parallel from the upper part to the lower part.

  Next, the lower end portion of the guide 53 attached to the fluid valve 4 inserted into the housing 10 is in contact with a stopper 52 provided on the inner surface of the housing 10 and below the guide piece 50. The fluid valve 4 is placed at the placement position of the predetermined location S. Since the placement position in the vertical direction of the fluid valve 4 placed in the housing 10 is specified by the stopper 52, the adjustment from the placement position of the fluid valve 4 described later to the connection position is adjusted in the planar direction. It can also be terminated with just
