Description
Technical field
Polyethylene structure wall tube material application field is the utility model is related to, is that a kind of heavy caliber HDPE structural walls quickly connect
Inspection shaft.
Background technology
Since 21 reality, every country is to start the construction of attention town and country county underground pipe gallery, as sustainable development
Major step, the building-up work of underground pipe gallery gets most of the attention.Furtherly, High molecular weight polyethylene is widely recognized as, and is
Second largest plastic conduit kind of consumption figure in the world, its duct products can be widely used for feedwater, agricultural irrigation, fuel gas transmission,
The fields, the especially downcomer in city and draining such as engineering and oil field, the chemical industry and post and telecommunications such as blowdown, the conveying of mine mortar
In many fields such as engineering, there is extremely prominent performance.
But traditional underground pipe gallery construction has all multi-risk Systems in some risk locations, as the change of physical features can not be supervised
Survey, the cost that volcanic belt, high earthquake zone and tubing infringement caused by high corrosion region can not be repaired or repaired in time is huge.
Constructional difficulties be present, while junction is weak, seepage often easily occurs because volume is big in traditional detection well.Even
The in irregular shape of place is connect, there is also the problems such as many processing difficulties, processing disunity.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of heavy caliber HDPE structural walls quickly connect
Connect inspection shaft, its using the high-quality corrosion resistance of high density polyethylene (HDPE), realize the observation to the work of underground pipe gallery construction work and
Repair.
The utility model realizes that the technical scheme of purpose is as follows：
A kind of heavy caliber HDPE structural walls quickly connect inspection shaft, including main pipeline inspection shaft, in main pipeline pipe side wall
On be formed with film viewing screen and artificial channel, bypass line is formed with the side wall of main pipeline inspection shaft and connects hole, bypass line connects hole
Interior radial direction is fixedly mounted with bypass line mouthpiece, and bypass line mouthpiece is used for input pipe bayonet joint in main pipeline inspection shaft side
On wall, the coaxially connected input pipe of bypass line mouthpiece；The bypass line mouthpiece connection end is female mouth, in female intraoral wall
Linkage section is formed with, a radial convex loop is formed with the middle part of linkage section, is embeded slot on the inside of bulge loop, is connection side outside bulge loop, even
It is spaced and parallel on edge fit to be fixedly mounted with two sealing copper wire rings；The input pipe connection end is rim of the mouth, and in rim of the mouth, foreign aid is formed with connection
Section, coaxially it is embedded in female intraoral linkage section, the embedded sealing ring in the middle part of the linkage section outer rim of rim of the mouth, sealing ring is coaxially fitted to branch road
In the embeded slot of pipe joint pipe connection end mother's mouth, the rim of the mouth inside sealing ring contacts with sealing copper wire ring.
Moreover, coaxially it is fixedly mounted with cushion in main pipeline inspection shaft inner edge.
The advantages of the application and technique effect are as follows：
The kind heavy caliber HDPE structured wall popes inspection shaft that the application provides is applied to the underground pipe gallery detection work of permeability,
Such as airport, the high-risk point monitoring of subway, and urban sewage piping lane.The monitoring well has excellent corrosion resistance, therefore has in underground
Extremely long service life.High density polyethylene (HDPE) is a kind of green material, and a kind of lightweighting materials, relative to other prisons
Well logging, it is more economical durable, the underground pipe gallery construction to adhering to sustainable development significance, there is positive meaning.
Branch mouth pipe in the application ensure that inside using the sealed quick connection of double sections, the sealing of first stage rubber ring type
The sealing of air pressure, the sealing of second stage rubber ring type serve sealing of the tubing to contact gap, realize zero seepage.
