Preferably, in described construction drainage pipeline air bag closed-water test device described in the utility model, described waterproof type cloth cover is interior outer double-layer structure, and its skin is PVC layer, and internal layer is terylene layer.

Preferably, in construction drainage pipeline air bag closed-water test device described in the utility model, the material of described rubber liner is latex.

Further, in construction drainage pipeline air bag closed-water test device described in the utility model, the link position of turnover valve and flexible pipe adds larynx hoop.

Preferably, in construction drainage pipeline air bag closed-water test device described in the utility model, after described rubber liner inflation, cross section biggest place diameter is 50 ~ 200mm.

Preferably, in construction drainage pipeline air bag closed-water test device described in the utility model, described rubber liner is spherical, elliposoidal or cylindrical.

Preferably, in construction drainage pipeline air bag closed-water test device described in the utility model, described flexible pipe is leather hose or sebific duct.

The utility model can be achieved as follows technique effect:

1, rubber liner of the present utility model, adopts slim high elasticity quality of rubber materials, and for example latex, has good elasticity and tightness.

2, the utility model rubber liner overcoat connects waterproof type cloth cover, can limit the maximum diameter of rubber liner inflation, owing to there being fabric restriction, inner bag just cannot expand after reaching certain diameter, be unlikely to break, and can also greatly improve the intensity of air bag entirety, in addition, waterproof type cloth cover is outer arranges PVC layer, can avoid the water inlet of cloth cover.

3, rubber liner external application flexible pipe Bonding pressure table and charging air inlet, wherein, pressure gauge can well be monitored air pressure, avoids excessive inflatable bladder explosion, and also observable goes out whether there is gas leakage situation.

4, charging air inlet can such as pump of external charger etc., adopts conventional equipment inflatable, facilitates easy to operate.

5, the present invention is mainly used in vertical drainage pipe, because high elasticity thin rubber inner bag and waterproof type cloth cover is very soft and easily folding, therefore can put into pipeline by drainage pipeline inspection opening, when use, inflate to rubber liner with pump, rubber liner elastic force is very large, inflation after and tube wall tightly fit, therefore pipeline can be blocked very soon.
