Description
Technical field
The present invention relates to technical field of construction, specifically a kind of sealed Grouting Pipe molding positioning of reinforced concrete sewer pipe
Device and its application method.
Background technology
Jacking construction method is widely used in rainwater, dirt with reinforced concrete sewer pipe (hereinafter referred to as concrete ceiling coil)
The gravity streams pipeline such as water, diversion and farmland discharging-irrigating in recent years, is also widely used for the high pressures power transmission and transformation line such as 220KV underground
The construction project of piping lane.The installation of concrete ceiling coil belongs to non-excavated jacking pipe laying product.
In entire concrete ceiling coil work progress, because between tube wall and surrounding soil there are frictional resistance, concrete
The axial Top power that push pipe is born with the difference of soil property, the length of apex distance, the difference of jacking construction method and change, axial direction
Jacking force is huge, in practical jacking construction, for the frictional resistance of concrete ceiling coil outer wall and underground is greatly lowered, leads to
In Chang Guan, by being mounted on socket position Grouting Pipe part slip casting outside pipe of concrete ceiling coil, to reach outside entire pipeline
Wall forms one layer of complete drop resistance mud sleeve with favorable lubricating property, achievees the purpose that reducing friction resistance, to realize peace
Entirely, lower resistance, long range, Curve Pipe Jacking.
Since the concrete that concrete ceiling coil uses is plastic concrete, mostly using vibration compacting moulding process, in tradition
Concrete ceiling coil molding die design, manufacture when, due to Grouting Pipe molding positioning device using sealing performance design,
Cause in the Grouting Pipe manufacturing process of concrete ceiling coil, concrete is under the high frequency tamping of vibrator, and cement mortar is constantly
It is permeated by gap into Grouting Pipe and Inner spiral shells, Grouting Pipe and Inner spiral shell screw threads is caused to be filled by concrete mortar, coagulated in screw thread
Gu cement mortar cleaning after is time-consuming, there are labor intensity is big, operating space is narrow, inefficiency etc., often because
Screw thread damage leads to the situation that Grouting Pipe is scrapped.
