Description
Technical field
The utility model is related to a kind of plumbing field, more particularly, to a kind of pipe connecting structure for accessing inspection shaft.
Background technology
, it is necessary to by the newly-built pipeline built inspection shaft of access in existing municipal drainage pipeline process of construction.Common access
Method is that newly-built pipeline is inserted into built inspection shaft after being burrowed on built inspection shaft, between newly-built pipeline and inspection shaft
Tamped with cement mortar in space.Because cement mortar setting time is more long, this way construction period is more long, and due to the chi that burrows
Very little whard to control, newly-built pipeline can not fit completely between inspection shaft, and cement mortar completely can not also tamp gap, in underground
After the prolonged immersion of water or water impact, cement mortar is easy to fall off, accumulates over a long period to form breakthrough, causes road surface filling chock next time
Stream is lost, and forms underground cavity pocket, causes surface collapse, causes security incident.
Utility model content
The purpose of this utility model is exactly a kind of simple structure, high treating effect to be provided to solve the above problems, is applied
Work facility, the convenient pipe connecting structure for accessing inspection shaft of maintenance.
The purpose of this utility model is achieved through the following technical solutions：
A kind of pipe connecting structure for accessing inspection shaft, including ventilating water pipe and ring flange sleeve pipe, described ring flange set
Pipe includes the ring flange of head and the sleeve pipe at rear portion, and rubber layer, described ventilating water pipe insertion are provided with the inner and outer surfaces of sleeve pipe
In ring flange sleeve pipe.
Described ring flange sleeve pipe is installed in the perforate for checking the borehole wall, and ring flange is fixed on inspection shaft by expansion bolt
On wall.
Described rubber layer uses the elastomeric material of water-swellable, selected from selected from neoprene, ethylene propylene diene rubber, Ding Qing
One kind of rubber or Sodium Polyacrylate.
Described rubber layer is located at ring flange sleeve pipe and checks the inner surface and the appearance with ventilating water pipe of borehole wall perforate
Between face.
Described rubber layer pastes the inner and outer surfaces in sleeve pipe by glue, and the thickness of rubber layer is 15-25mm.
The length of described ring flange sleeve pipe is more than the wall thickness for checking the borehole wall.
Described casing inner diameter 30-50mm bigger than ventilating water pipe external diameter, sleeve outer is than checking the small 30- of borehole wall opening diameter
50mm, the opening diameter with diameter greater than the inspection borehole wall of ring flange.
Described pipe applications specifically include following steps in inspection shaft：
A () manufacturing flange disk sleeve pipe, fastens with glue rubber layer in the inside and outside layer of sleeve pipe；
B () highly determines position of opening by the tube hub for intending accessing ventilating water pipe, the perforate on the borehole wall is checked；
C the insertion of ring flange sleeve pipe is checked in the perforate of the borehole wall, ring flange is fixed on into inspection shaft by expansion bolt by ()
On wall；
D () inserts in ring flange sleeve pipe ventilating water pipe.
Step (b) throws row perforate, reaming into using wall hole making drill circulating sleeve.
Compared with prior art, the utility model has advantages below：(1) ring flange is straight with diameter greater than inspection borehole wall perforate
Footpath, after ring flange covering is installed on into the perforate of inspection borehole wall institute, can effectively prevent current in inspection shaft from being caused to void filler
Impact；(2) because ring flange casing inner diameter is chosen according to new access conduit external diameter, can accomplish that inner and outer pipes are fitted completely；(3) sleeve pipe
It is inside and outside it is viscous filled in hydro-expansive rubber, can effectively prevent the outer underground water of inspection shaft from entering inspection shaft by space, and when well body hair
During raw differential settlement, also due to the elasticity of rubber, can effectively prevent well body from settling the bending damage to pipeline；(4) this reality
Carry out perforate using metope hole making drill with new, can effectively prevent it is conventional strike, the destruction that sinking shaft wall is produced to well body, raising perforate
Precision, while improving efficiency of construction, after newly-built pipeline inserts mounted sleeve pipe, can come into operation immediately, can effectively prevent from connecing
Access point seepage, greatly improves efficiency of construction, shortens construction period.
