Description
Technical field
The present invention relates to caliber and non-excavation pipeline construction field, especially a kind of socket joint embeds self-hard steel plastic compount and puts entirely
To dilatory pipe.
Background technique
Pass through urban road, highway, railway, lake, river bury DN80-DN1000 underground utilities it is more and more difficult.
The appearance of Directional Drilling hauling construction method avoids the excavation of road and the damage to other underground utilities, while reducing underground
To the influence of traffic, environment when pipeline construction.
Using Directional Drilling hauling construction method, directional drilling track is three-dimensional " snakelike " parabolic shape.Directional Drilling hauling construction
The dilatory length of tube of method is drawn pipe in process of production, due to the requirement stored and transported, need to will be dragged from tens of rice to upper km
Trombone slide is cut into section, need for short section pipe to be connected as in construction a satisfactory long tube and have can flexing physical property,
And existing dilatory pipe generally uses the welded still pipe for having flexible HDPE plastic pipe or sacrifice length to obtain around curvature, however mould
When the dilatory pipe of material draws too long, due to the disadvantage that tensile strength is inadequate, surface hardness is inadequate, plastic material is easily adulterated, easily
It causes to draw the hidden danger of quality such as tubing snaps, bore deforms, pipe outer wall seriously scratches, the cumbersome heat of sweat soldering interface complex process
Melting temperatur requires harshness etc., and welded still pipe generally uses anti-corrosion, the connection of joint weld technique outside five oily three cloth, for dilatory pipe
When sacrifice length acquisition and largely waste material around curvature and increase cost, without interior anti-corrosion at soldering opening, outer anti-corrosion is in directional drilling
Interior dilatory five oily three cloth that scrape are unable to reach requirement for anticorrosion influence pipeline service life, welding procedure complexity cumbersome requirements height etc..
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of socket joint embed self-hard steel plastic compount be flapped toward entirely it is dilatory
Pipe.
The technical solution of the present invention is as follows: a kind of socket joint embeds self-hard steel plastic compount is flapped toward dilatory pipe entirely, comprising:
The both ends of steel pipe, the steel pipe have faucet section and socket section, after the faucet section per adjacent previous steel pipe is inserted into
In the socket section of one steel pipe；
Spacing collar, the spacing collar are fixed in faucet section；
Connector and elastic ring, described connector one end are connected in socket section, the connector other end and limit steel
It is embedded with elastic ring between circle, faucet section and socket section are fastenedly connected；
Sealing rubber ring, the sealing rubber ring are embedded in the gap between the faucet section and socket section.
Preferably, it is opened up in the socket section fluted.
Preferably, the connector is self-hard mechanism, and the both ends of self-hard mechanism have convex edge edge.
Preferably, one end convex edge matches of the self-hard mechanism are caught in groove, and other end convex edge edge is blocked
The elastic ring.
Preferably, the spacing collar is limit steel ring, and limit steel ring is fixed in the faucet section.
Preferably, the spacing collar is the integrally formed limit segmental arc of faucet section.
Preferably, the elastic ring is self-locking spring circle.
Preferably, the self-locking spring circle is self-locking c-type spring ring.
Preferably, the steel pipe is externally provided with anti-corrosion scratch resistant layer；Anti-corrosion scratch resistant layer is high-density polyethylene layer.
Preferably, the contact between the elastic ring and limit steel ring is point contact.
Compared with prior art, the invention has the following beneficial effects:
(1) pulling capacity is big, this dilatory pipe according to caliber size can load 150KN to 8000KN do not break off relations.Axial thrust=
Sectional area * pressure；
(2) swing angle is big, due to this self-hard interface, contacts and draws the faucet section of pipe for point contact and socket section is being dragged
4-16 ° of swing angle can be realized when drawing；
(3) it can be swung with 360 ° omni-directional, adapt to three-dimensional " snakelike " parabola and swing；
(4) long production is ordered, can be formulated according to condition of construction 0.5 meter -12 meters every long；
(5) traverse distance is long, enters nozzle and outlet spout draws length up to one kilometer；
(6) T-type slides into socket joint connection, can bear water pressure 10Mpa in pipe；
(7) without external power supply and connection equipment when drawing pipe installation connection；
(8) outer pipe wall is using epoxy resin+adhesive+HDPE winding band winding or strong concrete package protection
Ensure that outer anti-corrosion is safe and reliable；
(9) interior anti-corrosion can be according to the difference of trandfer fluid using preserving timbers such as epoxy resin, HDPE, concrete, stainless steels
Material；
(10) it is greater than tube body wall thickness from fixing structure and the self-locking steel ring contact tang wall thickness of elasticity, experiments have shown that the limit is axially drawn
Pull out force lower tube body (disconnected) the self-hard interface that bursts apart is not damaged, " not breaking off relations ".
