DETAILED DESCRIPTION
[0025] The following embodiments are only a part of the technical solution of the present utility model, and are not intended to limit the entire technical solution of the present utility model. The embodiments of the present utility model are provided to further explain and illustrate the details of the technical solution of the present utility model.
[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 shown.
[0027] A movable inner support device for controlling local deformation of a rubber dam bag, the device comprising a rubber dam bag 1, a guide slide 2, a pressure sensor 3, a signal transmitter 4, a positioning block 5, a power cord 6, a repair airbag 7, an inflation port 8, an inflation tube 9, a traction rope 10, a pressure relief port 11, a traction rope winch 12, a protective sleeve 13, an inflation device 14, and a power supply device 15.
[0028] The repair airbag 7 is cylindrical in shape after being inflated. The repair airbag 7 is made of a tape product made of nylon canvas skeleton material and rubber airtight material vulcanized, using three cloths and four rubbers, model JBD5.0-400360-3, and adopts an inner lap joint form without lap seams on the surface. The aforementioned tape should be resistant to aging and wear, with fewer wrinkles when inflated and flat after exhaust. After inflation, it expands, fits tightly with the rubber dam bag 1 and provides radial support force, thereby repairing the local deformation of the dam bag upward to eliminate the notch. The inflation pressure in the repair airbag 7 shall not exceed the design pressure. The main loads of the repair airbag 7 design are the inflation pressure in the dam bag and the inflation pressure in the airbag. The pressure ratio between the airbag and the dam bag should be selected from 1.0 to 1.1. The filling and exhaust control equipment of the repair airbag 7 and the dam bag use the same set of equipment. The movement of the repair airbag 7 is dragged to the vertical deformation of the dam bag by the traction rope winch 12 before the rubber dam collapses or before exhausting. In order to protect the repair airbag 7 from being scratched and damaged, the inflation port and the exhaust port of the rubber dam bag 1 can be provided with protective caps.
[0029] The guide slides 2 are evenly distributed outside the circumference of the repair airbag 7, and the number is 12. They are made of rubber, have a semicircular cross section, and are equal in length to the repair airbag 7. The bottom wide side 2.1 of the guide slide 2 is firmly attached to the repair airbag 7 with an adhesive, and the dome side 2.2 is coated with a lubricant. After the repair airbag 7 is inflated, the guide slide 2 should fit tightly with the rubber dam bag 1.
[0030] The protective sleeve 13 is arranged in the bank walls at both ends of the rubber dam, one end is connected to the rubber dam bag 1, and the other end is connected to the control room. The pipeline of the protective sleeve should be provided with fewer elbows, and the bending angle of the elbow is not less than 60 degrees. The traction rope 10 is passed through the protective sleeve, and the inner diameter of the protective sleeve is not less than 100 mm. A sealing plug is used at one end of the control room to seal it tightly and prevent air leakage.
[0031] There are two traction ropes 10, one end of which is connected to one end of the repair airbag 7, and the other end is connected to a traction rope winch 12. By winding the traction rope 10 with the winch, the repair airbag 7 can be pulled to move along the axis of the dam bag in the rubber dam bag, and the winch winding can be driven by electricity or manually rotated.
[0032] The inflation tube 9 is connected to the repair airbag 7 through an inflation port 8, and the inflation tube 9 is laid at the inner bottom of the rubber dam bag in a pressure-bearing hose curve.
[0033] The inflation port 8 is arranged at the lower part of one end of the repair airbag 7 and is connected to the inflation tube 9.
[0034] The pressure relief port 11 is arranged at the upper part of one end of the repair airbag 7, and is arranged at a different end from the inflation port 8. It is used for exhausting when the dam collapses and for the overpressure safety valve function during pressure increase and operation.
[0035] The pressure sensor 3 is arranged on the side of the repair airbag 7 and connected to the signal transmitter 4. The signal transmitter 4 is arranged beside the pressure sensor 3 and connected to the pressure sensor 3. The pressure sensor 3 sends the pressure detection data in the airbag to the data display screen in the control room through the signal transmitter 4, and the management personnel dynamically adjust the pressure according to the pressure data.
[0036] The power line 6 is arranged beside the signal transmitter 4 to provide low-voltage power to the pressure sensor 3 , the signal transmitter 4 and the positioning block 5 .
[0037] The positioning blocks 5 are arranged at the middle and both ends of the repair airbag 7, and the total number is 3. The positioning blocks 5 use position sensors and are attached to both sides and the top surface of the repair airbag 7. When the position of the repair airbag 7 is moved, the position of the repair airbag 7 is transmitted to the control room through the signal transmitter 4.
[0038] The traction rope winch 12 is arranged in the control room and connected to the traction rope 10 .
[0039] The utility model partially explains the principle: the repair airbag 7 is moved and dragged to the vertical deformation of the dam bag through the traction rope winch 12. The repair airbag 7 expands after being inflated, fits tightly with the rubber dam bag 1 and provides radial support force, thereby repairing the local deformation of the dam bag upward to eliminate the notch.
[0040] The construction method of the utility model is as follows:
[0041] When the rubber dam civil engineering is implemented, protective casings 13 are buried in the shore walls at both ends, and a traction rope winch 12 is installed in the control room.
