Splice device body includes：
Check-valves, the check-valves have outer silk and internal thread；
There is screw thread, the threaded one end of the slip casting short tube to connect check-valves for slip casting short tube, the slip casting short tube both ends,
The other end of the slip casting short tube connects Grouting Pipe；
Positioning cards, the positioning cards connect check-valves；
Fixed iron hoop, the fixation iron hoop are fixedly connected with advanced tubule tail portion；
Gasket seal, the gasket seal are set between positioning cards and fixed iron hoop.
The check-valves is preferably cast iron check-valves.
The positioning cards are preferably steel gasket.
The gasket seal is preferably rubber sheet gasket.
The fixation iron hoop is welded to connect with the advanced tubule tail portion, and the fixation iron hoop is rolled up by 8 round steel of Ф
Ring is made.
The installation method of the quick coupling device includes the following steps：
A, positioning cards are passed through into silk part outside check-valves, is welded in the outer silk tail portion of check-valves；
B, slip casting short tube is threadedly connected to check-valves internal thread part, the slip casting short tube other end is connected into Grouting Pipe；
C, gasket seal is passed through into silk part outside check-valves, be tightly attached in positioning cards；
D, by silk partial insertion advanced tubule tail end outside check-valves, until the fixation iron hoop of advanced tubule end with it is close
Gasket fits closely；
E, quick coupling device ontology will be connected with movable dog and advanced tubule fastens.
In step e, the fixation iron hoop of positioning cards and advanced tubule tail end is fastened by movable dog, it is thus real
It now will connection quick coupling device ontology and advanced tubule fastening.
Slip casing by pressure can be carried out after the step e, after waiting for slip casing by pressure, cement mortar initial set, you can remove fast
Quick coupling device, and accomplish to clean in time, it recycles.
The utility model compared with the existing technology, the advantage is that the utility model solves existing advanced tubule note
Slurry connector work efficiency is low, sealing is poor, takes material, the problem that construction is difficult.The utility model compact structure is convenient, operation is flexible, sealing
Property it is good, safe and reliable, can be recycled, while improving work efficiency, saved material, ensure that quality, is safe and reliable, have compared with
High application and promotional value.
