Lobe and depressed part.
During push pipe docking, the front port of a push pipe clashes into the rear port of another push pipe, and lobe increases with depressed part
Having added the lifting surface area of push pipe joint, pressure during shock can be distributed on lobe and depressed part, during push pipe docking not
Easy fracture；Being inlayed with depressed part by lobe simultaneously and be connected, the connection of two push pipes is tightr.
This utility model is further arranged to: described lobe is shaped as circular arc with depressed part.
Push pipe can rotate during heading into, and two push pipes produce skew, the lobe of circular arc and depression relatively
Portion make two push pipes when docking, can correcting offset angle, it is to avoid skew causes the change of push pipe advance circuit, passes through lobe
With depressed part, two push pipes abut.
This utility model is further arranged to: is provided with the first planar end surface inside described front port, sets inside described rear port
Have the second planar end surface abutted with the first planar end surface, described first planar end surface to be provided with some to be along the circumferential direction spacedly distributed
Groove, is provided with cork gasket in described groove.
Cork gasket is arranged on the end face of push pipe, plays buffer protection effect when two push pipes clash into；It is simultaneously embedded in
Cork gasket in groove, does not falls out when push pipe transports yet, is connected firmly with push pipe.
This utility model is further arranged to: is provided with the first annular groove outside described front port, is provided with outside described rear port
Second annular groove, is provided with, between described first annular groove and the second annular groove, the sealing ring being tightly connected.
The outer shroud of push pipe is provided with sealing ring, and sealing ring is contained between the first annular groove and the second annular groove, when push pipe is laid on soil
In layer, what the structure of the first annular groove and the second annular groove added junction climbs water distance, when soil layer has infiltration, needs through
The concave structure of annular groove, plays and prevents the effect that in soil layer, water and soil and mud flow backwards.
This utility model is further arranged to: described push pipe inner surface is provided with the grooved rail passed through for transporter.
After push pipe press-in soil layer, the earth in the push pipe front that needs to scoop away, transported by transporter, tube wall is circular arc
Structure, the wheel of transporter is placed in grooved rail, it is to avoid transporter rollover in use, makes transportation lighter.
This utility model is further arranged to: described push pipe outer surface is provided with the wire casing for fixing outside lifting line.
After push pipe needs to be fixed by lifting line, vertically put into push pipe and lay mouth, head into soil layer one by one, pass through outer surface
On wire casing, lifting line can be conveniently fixed on push pipe, prevent push pipe skid off during hanging lifting line and drop.
This utility model is further arranged to: being shaped as of described lobe and depressed part is trapezoidal.
Trapezoidal lobe is plane with the outer surface of depressed part, facilitates the cutting manufacture of push pipe, connects tighter between push pipe
Close.
By using technique scheme, this utility model has the advantages that when push pipe docks not easy fracture, top
It is tightly connected between pipe, conveniently transports.
Compared with prior art, the utility model has the advantage of: during push pipe docking lifting surface area greatly, not easy fracture.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment 1: a kind of push pipe docking structure, such as Fig. 1, including two push pipes 1, push pipe 1 two ends are respectively side a and b,
The A end of one push pipe 1 is connected with the B end of another push pipe 1, and push pipe 1 is divided into three layers from the inside to the outside.
A end: outer layer is provided with the first annular groove 2.Intermediate layer is provided with lobe 4 and the depressed part 5 of circular arc, and lobe 4 is with recessed
Fall into portion 5 shape complementarity.Internal layer is provided with the first planar end surface 6, is provided with 6 and is along the circumferential direction spacedly distributed in the first planar end surface 6
Groove 8, is provided with square cork gasket 9 in groove 8.
B end: outer layer is provided with the second annular groove 3, such as Fig. 2 and Fig. 3, is provided with sealing ring 13 between the first annular groove 2 and the second annular groove 3.
