Plugging airbags using method

First, inflatable pipe plugging airbag use method

German vetter Witt 1.5 Bar Inner Sealing Bag

1. Preparation: First, combine the accessories of the water-suppressing airbag inflator to make a tool leak check. Place the water-suppressing air bag in a bucket filled with water and hold it. Inflate the water-suppressing air bag with the air bag and check whether the water-seal bag leaks.

2 , open the riser check port, the water blocking air bag slowly from this port into the about 0.2m , and then inflate the water blocking air bag, so that the water blocking air bag and the inner wall of the tube is in close contact with the water is not leakage degree. The staff was inflated in the lower floor and the upper floor was filled with water. Pay attention, stop water

Avoid placing on riser fitting joints for the following reasons:

( 1 ) There are joints on the inner wall of this place, which affects the tightness of water plugging.

( 2 ) In order to prevent the water blocking airbag from expanding to one side, the air pressure will not go up. If the airbag is inherited, the water blocking airbag will be broken. For cast iron drainage pipes, it is required that the sand is clean and the inner wall is flat. No burrs are allowed. Otherwise, the watertightness of plugging water will be impaired, and even the capsules will be punctured. Various sizes of water blocking air bags must be used in the corresponding pipelines, and they cannot be large and small.

3. Inject the water to the floor height at the water injection port on the floor (or at the inspection port), and then check the water injection pipe and fittings one by one. If any leaks are found, mark them and repair after draining; for example, The rubber ring flexible interface can be repaired with water tight bolts at the leaking interface. If there is no leakage point in the water injection pipeline inspection, the water level can be stabilized. The water injection time lasts for 15 minutes, and the water level for 5 minutes does not fall to the qualified level.

4. Deflate the water-suppressing air bag, then pull out the water-suppressing air bag. Be careful not to damage the water-sealable air bag. According to the design requirements, each structure must have a water-rejection test before the waterproof layer and the anti-corrosion layer are constructed after the concrete of the main structure has reached 100% design strength, so as to assess whether the water seepage of the sewage treatment structure meets the standard requirements, so as to avoid Leakage of sewage will pollute the environment again, and it will also prevent the steel bars in the reinforced concrete structure from being eroded and affect the safety of the structure. During this period, it should be noted that the closed water test must use clean water (do not use sewage ) and slowly discharge the water from the pool and find that the leakage point should be marked. The test water level shall be set to the highest level of normal use. After three days and nights of observation and recording, no leakage will occur and water will be gradually discharged.

Second, lanes quickly plug the use of air bags

Rapid sealing of the balloon wall

1. Lane Closure Airbag Introduction

The quick sealing of the airbag in the laneway is a kind of rapid plugging device that can insulate the spread of the poisonous and harmful gas after the fire in the mine and the combustion. It is also called the mine rapid sealing wall. It is the use of compressed air instantaneous release rapid expansion of the principle of the plugging device quickly inflated to the mine tunnel cross-sectional shape, and according to the compressibility of the air to make the plugging device closely fit the shape of the mine tunnel section, to prevent the spread of toxic and harmful gases purpose.

2. The characteristics of airbags sealed in Zhongmu tunnel

(1) Easy operation: When emergency rescue workers or staff members need to plug and construct toxic and hazardous gas barriers in the fire zone in the ventilation tunnel, the air bag is not placed in the position of the barrier, and only the gas cylinder is opened after deployment. Inflatable. The rapid temporary sealing device will automatically expand and block the roadway to achieve the purpose of isolating toxic and harmful gases.

(2) Blocking speed: After the gas tank is opened by the rapid temporary sealing device of the mine. In 2 minutes, the closed roadway can be closed.

(3) Strong maneuverability: The device can be folded and stored at ordinary times, and only need to open the inflation when using.

(4) The scope of application is wide: it can be used as rescue personnel for rescue and rescue, and can also be used as a temporary confined use when working staff. In addition, in order to facilitate emergency personnel or staff access, there is a lifesaving channel in the middle.

3, lane sealing function of airbag

Compared with the traditional plugging device, the Zhonghao brand laneway plugging airbag has the characteristics of simple operation, fast wind speed, strong mobility, and wide application range. It is the “protective god” for underground fire fighting and rescue. When the device is adapted to coal mine fires or gas leaks, for fast sealing mine tunnel, roadway cutting airflow, isolated from the air into the fire zone, so anoxic zone immediately extinguished the fire, but also blocking gas fleeing zone. At the same time, workers in the fire area or gas leakage area can quickly evacuation through the airbag type fast and safe closed channel.

The fast airtight airbag has the advantages of light weight, simple operation, quick installation, wide application range, freedom from roadway section, geometry, type of bracket, strong randomness, and its material is flame-retardant, antistatic, impact-resistance, and softness. Features.
