Just it, can avoid the contraction baffle device for water for municipal sewage well trepanning of underwater operation.
To achieve the goals above, the utility model uses following technical scheme:
A kind of contraction baffle device for water for municipal sewage well trepanning described in the utility model, including water fender, waterproof
Item and cable wire, it is characterised in that:The two panels water fender is " V "-shaped to be arranged and passes through hinge between the inboard side of two panels water fender
Chain link constitutes openable and closable integral structure, and the outside of hinge is equipped with waterproof covering, and the both sides of waterproof covering are glued respectively to two
On the lateral surface of piece water fender, water-proof strip, the both ends difference of several cable wires are equipped in the outer side edges of the water fender and bottom edge
It is fixedly connected with two panels water fender and constitutes stable three-legged structure.
According to above scheme, the pressing plate of fixed water-proof strip, pressing plate are equipped in the outer side edges of the water fender and bottom edge
It is bolted with water fender.
According to above scheme, the water-proof strip is p-type rubber water-proof item.
According to above scheme, the inboard face of the water fender is equipped with several crosspieces of putting more energy into, crosspiece compartment of terrain successively of putting more energy into
It is welded on water fender.
According to above scheme, the crosspiece of putting more energy into is equipped with the fixed ring of connection cable wire, and the both ends of several cable wires connect respectively
It is connected in corresponding fixed ring.
The utility model has the beneficial effect that:The utility model is reasonable for structure, puts into inspection shaft, arrives after water fender is folded
The side that is placed on and need to punch to maximum spreading angle is opened after up to big cross section position and abuts well inner wall, makes water fender and shaft bottom
It completely attaches to, then suction pump is put into and is drawn water between water fender and the borehole wall, water fender can be under effect of water pressure by pressure tightly
On the borehole wall, steel cable meeting auto-tensioning bears the pulling force of expansion, and rubber water-proof item can be close to the borehole wall and constitute sealing, to realize
Anhydrous tap operation.

Specific implementation mode
The technical solution of the utility model is illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of contraction baffle device for water for municipal sewage well trepanning described in the utility model, including gear
Water plate 1, water-proof strip 2 and cable wire 3, it is characterised in that:The two panels water fender 1 is " V "-shaped to be arranged and in two panels water fender 1
Openable and closable integral structure is connected and composed by hinge 4 between side, the outside of hinge 4 is equipped with waterproof covering 41, waterproof covering
41 both sides are glued respectively on the lateral surface of two panels water fender 1, and waterproof is equipped on the outer side edges of the water fender 1 and bottom edge
Item 2, the both ends of several cable wires 3 are fixedly connected with two panels water fender 1 respectively constitutes stable three-legged structure;General municipal sewers
Road inspection shaft is made of upper and lower two cylinders, and general 2000mm of lower part drum diameter or so, each pipeline connects herein, top circle
Cylinder size is about diameter 700mm, water level following 500mm or so generally at the top of large cylinder well in well, the width setting of water fender 1
