The central line of the perforating pipe and the central line of the capsule body are arranged in parallel, and one end of the perforating pipe, which is far away from the pressurizing opening, is a flaring section.

According to the scheme, through the arrangement of the feed-through pipe, on one hand, the water blocking function of the water blocking bag can be ensured, on the other hand, water on the upper and lower streams of the repairing pipe section can be conveniently dredged, and meanwhile, one end, far away from the pressurizing port, of the feed-through pipe is designed to be in the form of the flaring section, so that water on the upper and lower streams of the repairing pipe section is relatively stable, and impact generated when the water blocking bag enters and leaves can be avoided.

The other end of the feed-through pipe is a quick-release movable joint. This makes assembly or disassembly on site more convenient.

Another further proposal is that more than two leakage-proof rings are arranged on the outer surface of the capsule body along the axial direction at intervals. This scheme has strengthened the sealed effect of stifled water pocket, provides the guarantee for the construction in the restoration section.

A further embodiment is one wherein said leakage prevention ring is arranged at said flared section. The advantage of this scheme is that this way leak protection ring has still played the enhancement supporting role to the flaring section that the structure is weak relatively.

The further proposal is that the pressurizing port is a liquid pressurizing port. The water blocking bag is pressurized by adopting liquid, so that on one hand, the water blocking bag has the advantage of being capable of taking water on site, and on the other hand, the noise caused by inflation is effectively eliminated.

To achieve the above another object, the present invention provides a plugging diversion device comprising a pair of water plugging bags according to the above solutions.

The water plugging device further comprises an overrunning pipe, wherein two ends of the overrunning pipe are connected with the other ends of the pair of water plugging bags through quick-release movable joints respectively.

A further proposal is that the overrunning pipe is provided with a water pump. The excess water can be relatively increased according to actual needs.

The device further comprises a charging control unit, and the charging control unit is provided with a pressure maintaining pump. The advantage of this scheme is to the construction occasion that needs relatively long term, is convenient for provide the sealed guarantee of stifled water.

Detailed Description

Embodiment of the Water shutoff bag

Referring to fig. 1, the water shutoff bag 1 has a bag body 11 with a substantially cylindrical shape, a pressurizing port 13 for pressurizing and discharging is provided at one axial end, the center line of the through pipe 12 is arranged in line with the center line of the bag body 11, wherein the end far away from the pressurizing port 13 is a flared section 121, that is, the flared section 121 has a frustum-shaped opening. At the other end of the feed-through 12 is a quick release union 122 for interfacing with an overtaking tube. On the outer surface of the capsule 11, four leakage-proof rings 14 are axially arranged at intervals, wherein one leakage-proof ring 14 is arranged at the flared section 121.

The water blocking bag 1 can also have other embodiments, such as the shape of the bag body 11 can also be determined according to the specific section shape of the water supply and drainage pipe. The centerline of the feed-through 12 may be non-collinear with the centerline of the balloon 11, but parallel and at a certain distance from each other, which may allow a relatively narrow repair tube segment to have a repair space more convenient for construction, and may allow a repair spot to have a relatively large space. In addition, in some construction occasions where noise influence does not need to be considered and air sources are convenient, the pressure charging port can be used for charging and discharging air instead of charging liquid.

Plugging and diversion device embodiment

Referring to fig. 2, the plugging and guiding device has a pair of the above-mentioned plugging water bags 1, and both ends of an overrunning pipe 2 with a water pump 21 arranged in the middle are respectively connected to the quick release movable joints 122 of each plugging water bag 1. The pressurizing ports 13 of the two water plugging bags 1 are connected with the output pipe end of the pressurizing unit 3 through the pressure pipe 4. The charging unit 3 has a charging pump 31, a holding pressure pump 32, a pressure relief valve 33 and a pressure relief valve 34, and the input ends of the charging pump 31 and the holding pressure pump 32 are connected with water sources.

The plugging diversion device may have other embodiments, for example, for the repair with a very simple repair section, in the case of a short repair time, the water pump 21 may be omitted, and the pressurizing unit 3 may also be simplified as omitting the pressure maintaining pump 32, and even omitting the pressure relief valve 33 and the overflow valve 34. For occasions needing long-time repair, in order to further improve the sealing effect, a plurality of water plugging bags can be connected in series to form a pair of water plugging bags connected in series.

The use process of the plugging diversion device can be seen in fig. 3, when trenchless repair is carried out on a water supply and drainage pipe, a water supply and drainage well cover with the upstream side and the downstream side on the ground 6 is uncovered, the water plugging bag 1 is placed into the water supply and drainage well by using a support or a rope, the water plugging bag 1 in an un-pressurized state is placed into a pipe orifice to be plugged, the surpassing pipe 2 and the water pump 21 are connected, the pressurizing unit and the pressure pipe 4 are charged, the pressurizing unit 3 is started for rapid pressurization, rapid stamping is stopped when the pressure is charged to be close to the set pressure, and the system is switched to slowly boost the pressure to the set pressure. The leak-proof ring 14 is tightly attached to the pipe wall, and the repair section 5 is separated from the upstream section 51 and the downstream section 52, at this time, the video monitoring system can be used for observing to confirm whether the plugging is tight and the drainage is smooth. And when no problem is confirmed, the pressurizing unit is switched to a pressure maintaining state, and the repairing construction is carried out under the condition of always maintaining good plugging.
