The anticreep field of interface.
Background technology
In recent years, as country's beginning starts to have an effect in municipal downcomer network engineering, the various heavy calibers for water delivery
Pipeline starts to flourish, particularly recent years, with the continuous decline and the continuous improvement of steel rolling technology of price of steel product, greatly
Bore steel pipe has been initially entered as the substitute products of PCCP pipe of cements and ductile iron pipe in the construction of urban pipe network, traditional skill
Art generally uses steel pipe both sides butt welding girth joint, technology relative maturity, but there is following defect：
(1) engineering time is long, labor intensive material resources；
(2) it is rigidly connected, stress concentration is easily broken off；
(3) need to carry out secondary anti-corrosion after welding repaired mouth, influence antiseptic effect.
Utility model content
The purpose of this utility model is to provide a kind of spigot-and-socket steel pipe anticreep mouthful device, and using flexible connection, stress is more preferable；
Easy construction, realizes an anti-corrosion, favorable anti-corrosion effect.
Spigot-and-socket steel pipe anticreep mouthful device described in the utility model, including steel pipe insertion end, steel pipe insertion end is provided with slotting
Enter and hold groove, in addition to steel pipe bell end, steel pipe bell end diameter is smaller than steel pipe insertion end diameter, steel pipe bell end is provided with socket joint
Hold groove.
Two sections need the steel pipe connected, and first segment steel pipe first end is steel pipe insertion end, and second section steel pipe first end is steel
Pipe bell end, steel pipe insertion end is inserted into outside steel pipe bell end, and insertion end groove is inserted into outside bell end groove, and insertion end is recessed
Groove and the mutual clamping of bell end groove, first segment steel pipe and second section steel pipe can mutually rotate, it can however not relatively front and rear move
It is dynamic, reach the purpose of anticreep.
It is further preferred that insertion end groove and bell end groove are adapted and set.Insertion end groove and bell end groove
Mutual clamping, slightly has gap, steel pipe insertion end and steel pipe bell end being capable of relative rotations between insertion end groove and bell end groove
Turn, still, steel pipe insertion end and steel pipe bell end can not be moved axially relatively, and reach the purpose of the two anti-disengagements of section steel pipe.
It is further preferred that steel pipe insertion end end opens up insertion end fluting.Steel is easy for for steel pipe axial deformation, one
Pipe insertion end inserts steel pipe bell end；Two when being that two section steel pipes fail correct install, and hydraulic cylinder can be used to pull insertion end to slot
It is easy to construction and installation again to disengage two section steel pipes in two ends.
It is further preferred that insertion end groove width accounts for 0.5-1 times of diameter of steel tube.Insertion end groove width needs suitable
When, the intensity of insertion end should be ensured, again ensure insertion end deformation quantity.
It is further preferred that the depth of insertion end fluting is to insertion end groove.
It is further preferred that the depth of insertion end fluting is between insertion end groove two edges.It ensure that insertion end is strong
Degree, it is ensured that anti-can be disengaged after two section fastener for connection, while ensure the deformation quantity of insertion end again, weight after being easily installed and disengaging
It is new to install.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model is by setting adaptable insertion end groove and bell end groove, realizes two sections of steel pipes
Flexible connection, has reached purpose of the motion in zone of reasonableness between steel pipe and steel pipe, and stress is more preferable；
(2) by setting insertion end groove and bell end groove, it time processing can be finished in factory, one can be realized
Secondary property anti-corrosion, can realize not hot work, enormously simplify on-site construction operations, shorten the engineering time during field operation,
Earthwork excavated volume is reduced, manpower and materials are saved；
(3) by setting insertion end to slot, during two sections of fastener for connection, it can be produced during steel pipe insertion end insertion steel pipe bell end
Raw axial deformation, insertion end groove insertion bell end groove, steel pipe can be rotated against each other, but immovable, utilize steel pipe
Surrender elasticity reach the anticreep of steel pipe, reached the purpose of anticreep.When steel pipe fails correct install, hydraulic cylinder can be passed through
Insertion end fluting two ends are tensed, insertion end groove and bell end groove is disengaged, two is disengaged and saves steel pipe, again construction and installation.
Brief description of the drawings
Fig. 1 is the mouth of pipe cross-sectional view of an embodiment of the present utility model,
Fig. 2 is the assembling structure schematic diagram of an embodiment of the present utility model.
In figure：1st, steel pipe insertion end 2, insertion end groove 3, insertion end fluting 4, steel pipe bell end 5, bell end are recessed
Groove.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
As shown in Fig. 1~Fig. 2, spigot-and-socket steel pipe anticreep mouthful device described in the utility model, including steel pipe insertion end 1,
Steel pipe insertion end 1 is provided with insertion end groove 2, in addition to steel pipe bell end 4, and the diameter of steel pipe bell end 4 is than the diameter of steel pipe insertion end 1
Small, steel pipe bell end 4 is provided with bell end groove 5.Insertion end groove 2 and bell end groove 5, which are adapted, to be set.Steel pipe insertion end 1
End opens up insertion end fluting 3.Insertion end 3 width of fluting account for 0.5-1 times of diameter of steel tube.
The depth of insertion end fluting 3 can be arrived at insertion end groove 2.The depth of insertion end fluting 3 can also arrive insertion end
Between the two edges of groove 2.The intensity requirement of steel pipe insertion end 1 can either be met, disclosure satisfy that the deformation quantity of steel pipe insertion end 1 will again
Ask.
As shown in Fig. 2 A represents the width of insertion end fluting 3, B represents the depth of insertion end fluting 3.
The course of work or operation principle：
Two sections need the steel pipe connected, and first segment steel pipe first end is steel pipe insertion end 1, and second section steel pipe first end is steel
Pipe bell end 4, steel pipe insertion end 1 is inserted into outside steel pipe bell end 4, and insertion end fluting 3 is used for steel pipe and produces axial deformation, from
And, realize that insertion end groove 2 slips over bell end groove 5, insertion end groove 2 and bell end groove 5 are back-off form, therefore, insert
When entering to hold the groove 2 slip over bell end groove 5, first segment steel pipe can neither advance, and can not retreat, and two section steel pipes relative can turn
It is dynamic, but can not move forward and backward relatively, the flexible connection of first segment steel pipe and second section steel pipe is realized, the mesh of anticreep has been reached
's.
When first segment steel pipe and second section steel pipe fail correct install, 3 two ends of insertion end fluting can be tensed with hydraulic cylinder,
Disengage insertion end groove 2 and bell end groove 5, so that first segment steel pipe and second section steel pipe are disengaged, to apply again
Work is installed.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
