The aforementioned side index member, the cloth only index member, and the bottom index member may be separated from each other or may be integrally connected to each other (the cover member can be integrally formed because it is elastically deformed by the elastic force of the index member).

The first and second drainage holes 111a and 112a are formed in the first and second water film panel main bodies 111 and 112 in such a manner that two or more drainage holes 111a and 112a are formed in a stepwise manner, Because it is easy to work and prevent safety accidents.

The first and second opening and closing plates 111b and 112b can be formed in a plate-like shape for opening and closing the first and second drain holes 111a and 112a. So that the first and second drain holes 111a and 112a are closed, and the first and second drain holes 111a and 112a are separated and opened. Therefore, the first and second water film panel main bodies 111 and 112 are provided with rails for sliding and engaging the first and second open / close boards 111b and 112b.

The inclined portions are formed on the surfaces of the first and second opening and closing plates 111b and 121b and / or the first and second water film panel main bodies 111 and 112 to increase water tightness of the first and second drain holes 111a and 121a, Or a packing of an elastic material may be applied.

The first and second water film panel main bodies 111 and 112 are not limited to the above-described sliding type, and may be of a pivoting type in which the opposite ends of the main body 111 and 112 are folded by the folding actuator while being connected by hinges. Of course, the rotatable first and second water film panel main bodies include first and second drain holes (111a, 112a), first and second open / close plates (111b, 112b) formed in the sliding first and second water film panel main bodies (111, 112) The first and second drain holes and the first and second opening and closing plates are formed and the index member is arranged in the vicinity of the four sides and tightly and tightly adhered to the inner circumferential surface of the conduit 1 through the actuator.

Up to this point, the upstream side water dam panel 110 has been described as having a quadrangle. However, as shown in FIG. 5, the upstream side water dam panel 110 may have a circular shape corresponding to a circular conduit.

As shown in FIG. 5, the first and second water film panel main bodies 111 and 112 are formed in a semicircular shape so as to be symmetrically arranged left and right (or vertically), connected by a hinge and forcedly folded by one or more folding actuators 113 And is installed in the conduit (1) through the first manhole (2) and is folded when it is dismounted to the ground, and at the time of installation for the order, the index member in the periphery is tightly adhered to the inner circumferential surface of the conduit by the actuator . It is preferable that the index member is integrally formed so as to maintain reliable watertightness at the hinge connection portions of the first and second water film panel bodies 111 and 112.

As shown in FIG. 5, the first and second water film panel main bodies 111 and 112, which are formed in semicircular shapes and are symmetrically arranged and connected by hinges, respectively have first and second drain holes, first and second drain holes Plates 111b and 112b are formed.

The upstream side order portion 100 includes an upstream side strut 120 for imparting a compressive force to the upstream side water film panel 110. The upstream strut 120 is connected to the bottom of the conduit 1 at the bottom and one or more telescoping supports 121 supported at the top of the conduit 1 and to the bottom of the support 121, A support plate 121 connected to an upper portion of the support 121 and supported by the ceiling of the conduit 1; a support 121 and an upstream side dam plate 110; And a connecting member 124 for connecting.

The stretchable support 121 can be a hydraulic cylinder, a support in which two pipes having different diameters are connected to each other in a contractible manner and fixed with a tightening nut, or the like.

The bottom plate 122 and the top plate 123 are preferably rubber or the like having elasticity for ensuring watertightness.

The connection member 124 includes a hook portion 124a (a horizontal portion and a vertical portion) formed in the support 121, a connection bar 124b formed on the upstream side water film panel 110 and connected to the hook portion 124a, .

On the other hand, in the case where the discharge end of the other side of the induction pipe 300 is inserted into the third manhole 4 and the sewage introduced and drained through the induction pipe 300 is introduced into the pipe 1 to be treated, The downstream-side order portion 400 is preferably applied so as not to flow backward to the upstream side.

The downstream-side order portion 400 has the same configuration as the upstream-side order portion 100 (the downstream-side deck panel 410 and the downstream-side strut portion 420), and thus a detailed description thereof will be omitted.

The induction drainage frame 200 is a box-shaped structure for inducing and draining sewage filled in the first manhole 2 and opening at the bottom. Of course, the induction drainage frame 200 is composed of various shapes (circular, square, etc.) corresponding to the shape of the first manhole 2.

The induction drainage frame 200 is composed of a box-shaped frame body 210 and a flange 220 formed outwardly at the bottom of the frame body 210 and fixed to the ground (such as the first manhole 2) through anchoring or the like do.

Since the induction drainage frame 200 allows induction drainage of the sewage filled in the induction drainage hose 300, the inlet end of the induction drainage hose 300 must be connected in fluid communication.

A method of connecting the inlet end of the induction drainage hose 300 to the induction drainage mold 200 may be a method in which a tube joint 230 is projected laterally around the periphery of the frame body 210, The inlet end of the induction drain hose 300 is connected to the inlet end of the induction drain hose 300 by inserting the inlet end of the induction drain hose 300 into the pipe joint 230 and fixing it by a band.

That is, the tube joint 230 is not limited to a protruded tubular shape, but may have various shapes such as a shape of a hole.

In addition, when a relatively small pipe joint 230 is formed in the box-shaped drain mold main body 210, when the sewage flowing into the drain mold main body 210 is drained through the pipe joint 230, A funnel-shaped guide portion may be formed between the drain pan main body 210 and the pipe fitting portion 230 so that the cross-sectional area gradually narrows toward the pipe fitting portion 230.

When the sewage is guided and drained through the pipe joint 230 and the induction drain hose 300, the pipe joint 230 is formed so that the sewage can be naturally introduced and discharged to the induction drain hose 300 by the water level difference without using a separate pump. Is higher than the discharge end on the other side of the induction drain hose 300.

The upper part of the mold body 210 of the induction drainage mold 200 may be opened to allow an operator to move in and out of the mold 210. In this case, the lid 240 is applied so that sewage does not overflow through the upper opening part. The lid 240 may be detachably coupled to the frame body 210 through fasteners (bolts, nuts, clamps, etc.) and may be provided with a transparent or transparent portion so that the interior of the lid 240 can be checked from the outside.

The packing 250 is applied so that leakage of the sewage does not occur between the bottom of the induction drainage frame 200 and the ground. Although the packing 250 is shown as being separated in FIG. 2, it is preferable that the packing 250 is coupled to the flange 220 of the drain mold main body 210 to be watertight.

The induction drainage frame 200 may be provided with a support tab supported by the inner wall of the first manhole 2. [ The support jaw may be formed as a ring formed as a whole in the mold main body 210, at least one piece formed at a predetermined interval, or the like, which is formed to protrude toward the bottom of the inner peripheral surface of the mold main body 210, So that the effect of preventing the frame 200 from moving and not leaving it is derived.

In the meantime, the position of the pipe joint 230 is a drainage position of the sewage, and a height adjusting frame 200-1 is provided to allow the pipe joint 230 to be set to a position corresponding to a change in the water level of the sewage, (Shown in Fig. 3) are selectively used when necessary.

The height adjustment frame 200-1 has a cylindrical structure with both upper and lower sides opened. The lower portion is fixed to the first manhole 2 or the ground through anchoring or the like, and the upper portion is fixed to the flange 220 of the induction drainage frame 200 and the flange joint do.

One or more height adjusting frames 200-1 may be stacked to set the height of the pipe fittings 230 to various heights.

Since the induction drainage frame 200 is installed in the first manhole 2 higher than the ground, it is possible to prevent the fall of the pedestrian.

The induction drainage frame 200 can be installed not only in the first manhole 2 but also in the third manhole 4 in which the discharge end of the induction drainage hose 300 is accommodated. The tube portion of the induction drainage mold 200 to which the discharge end of the hose 300 is connected maintains a height lower than that of the tube of the induction drainage mold 200 installed in the first manhole 2. [

The induction drainage frame 200 can be divided into two or more so that it can be easily applied to manholes of various sizes.

The induction drainage hose 300 can be a variety of products such as an inexpensive hose such as an inexpensive plastic hose or a stainless steel pipe. This is because the induction drain hose 300 is connected to the induction draining mold 210 without using a separate supporting means, so that a flexible vinyl hose or the like can be used.

The induction drainage hose 300 may be disposed inside the conduit 1 through another manhole, for example, the third manhole 4 in the conduit 1 where the upstream-side order portion 100 is installed, (See FIG. 1), and is disposed at various places other than the conduits or conduits which are not in fluid communication with the conduit 1 to be repaired, thereby inducing and draining the sewage.

When the discharge end of the induction drain hose 300 is disposed in the third manhole 4 of the maintenance target vessel 1 in the above-described example, the sewage water that is inductively drained may flow toward the upstream side, The side order portion 400 is used. Otherwise, the downstream side order portion 400 is not used because the sewage will not flow back to the upstream side.

The following is a description of the method of ordering the secondary vessel according to the present invention.

1. Upstream order.

For example, when repairing the conduit between the first manhole 2 and the third manhole 4, the upstream side waterkill panel 110 of the upstream-side order portion 100 is inserted through the first manhole 2, The first and second water film panel main bodies 111 and 112 are gathered in a small volume or folded so that the upstream side water film panel 110 is not interfered with the first manhole 2 and the conduit 1. [

The first and second water film panels 111 and 112 are opened to install the upstream side water film panel 110 and then the first and second opening and closing plates 111b and 112b are lowered from the upper portion to the lower portion of the first and second drain holes 111a and 112a Thereby closing the first and second drain holes 111a and 112a. The first and second drainage holes 111a and 112a are formed in multiple stages and can be sequentially closed from the first and second drainage holes 111a and 112a disposed at the lower portion.

The upstream side support part 120 can be firmly installed by installing the upstream side support part 120 after entering the inside of the conduit through the second manhole 3. [

2. Downstream order.

The downstream side order portion 400 is provided when the sewage is stagnant on the upstream side by the upstream side order portion 100 and the sewage is bypassed to the third manhole 4 through the induction drainage hose 300.

Of course, the downstream side order portion 400 is not used when the sewage is bypassed through the induction drain hose 300 to another location.

3. Installation of induction draining frame and induction drain hose.

The induction drainage hood 300 is installed in the first manhole 2 and the inlet end of the induction drainage hose 300 is inserted into the pipe joint 240 and the discharge end is inserted into the third manhole 4.

Therefore, the sewage water received in the conduit 1 by the upstream-side order portion 100 rushes inside the induction drainage mold 200 via the first manhole 2, and when the water level reaches the conduit 240 The sewage flows into the induction drainage hose 300 after passing through the pipe joint 240 and is bypassed to the downstream side of the conduit 1 through the third manhole 4. [

When the maintenance of the conduit 1 is completed, the first and second open / close boards 111b and 112b of the first and second water film panels 111 and 112 of the upstream side water level portion 100 are separated, , 112a.
