The rectangular triangle of steel plate, long right-angle side and the lateral surface welding of the body in right angled triangle connect
Connect, short right-angle side is located at close to described one end for leading mud connection end and set along the body exterior normal direction, and described short straight
The relative acute angle of the arm of angle is located at close to one end of the guiding connection end;
The axis of at least four steel plate around the body is in equiangularly spaced setting, on the hypotenuse of each steel plate
Also there is blade.
Described miniature push pipe pine mud device, wherein:The guiding connection end is equipped with screw thread with the mud connection end of leading.
Described miniature push pipe pine mud device, wherein:The length of the long right-angle side is 60cm, and the length of short right-angle side is
10cm。
Described miniature push pipe pine mud device, wherein:Thickness of knife edge is 0.2cm, and the oblique angle of blade both sides is 60 °.
Described miniature push pipe pine mud device, wherein:Between steel plate and tube wall by the way of manual electric arc welding full weld
Connection, weld seam form is angle welding, and steel plate will be welded with the side of tube wall contact surface four.
Described miniature push pipe pine mud device, wherein:It is described guiding connection end be connected with guide pipe, it is described lead mud connection end and
Mud guiding tube connects.
Described miniature push pipe pine mud device, wherein:The diameter of guide pipe is less than mud guiding tube, in the guiding connection end and institute
State and be additionally provided with a reducing connector between guide pipe.
Described miniature push pipe pine mud device, wherein:The reducing connector is integrally conical, and one end is bigger diameter end, another
Hold and be connected for miner diameter end, the miner diameter end with the guide pipe, bigger diameter end is connected with the guiding connection end.
As can be seen here, the utility model have the advantage that for:
1. after the construction of miniature push pipe pine mud device, the jacking of later stage sewer line is more smooth, reduces pipeline jacking
During required for pressure.
2. being not used before miniature push pipe pine mud device, closely knit cohesive soil is run into, mud guiding tube or head jacking occurred
During because resistance it is excessive, can not jacking situation, after use, no longer run into the above situation.

Embodiment
As shown in Figure 1 and Figure 2, a kind of miniature push pipe pine mud device 1 provided by the utility model, including body 10 and at least
Four steel plates 11, wherein:
To be oriented to connection end 101, the other end is to lead mud connection end 102, the guiding connection end for one end of the body 10
101 are provided with external screw thread, and the mud connection end 102 of leading is provided with internal thread;
The 11 rectangular triangle of steel plate, long right-angle side and the lateral surface of the body 10 in right angled triangle are welded
Connection, short right-angle side is located at close to described one end for leading mud connection end 102 and set along the exterior normal direction of body 10, with institute
The relative acute angle of short right-angle side is stated to be located at close to one end of the guiding connection end 101;
The axis of at least four steel plate 11 around the body 10 is in equiangularly spaced setting, each steel plate 11
Also there is blade 111 (as shown in Figure 5) on hypotenuse.
The miniature Making programme of push pipe pine mud device 1 includes:Choose body 10 and processing --- cutting steel plate 11 --- steel
Plate 11 welds with body 10 --- and miniature push pipe pine mud device 1 is installed and jacking, specifically:
Choose body 10 and processing:A straight body 10 is chosen, its outer wall is polished and processing of rust removing.
Cut steel plate 11:The steel plate 11 that thickness is 1cm is selected, as shown in figure 4, cutting six pieces of right angle trigonometries on steel plate 11
Shape, long right-angle side length are 60cm, and short right-angle side length is 10cm;Sword processing is carried out to the hypotenuse of right angled triangle steel plate 11,
As shown in figure 5, the thickness of blade 111 is 0.2cm, two skew angles are 60 °.
Steel plate 11 welds with body 10:Steel plate 11 after the completion of cutting process is welded to the outer wall of body 10, welding uses
The mode full weld connection of manual electric arc welding, weld seam form is angle welding, and steel plate 11 will enter with the side of 10 wall contacts face of body four
Row welding.
When the utility model uses, after " guide pipe jacking " terminates, by the guiding of miniature push pipe pine mud device 1
Connection end 101 is connected through a screw thread with guide pipe 2, then leads mud connection end by what mud guiding tube 3 was connected to miniature push pipe pine mud device 1
102, you can " mud guiding tube jacking " step is carried out, because the front end of mud guiding tube 3 is connected with miniature push pipe pine mud device 1, and miniature top
There is the blade 111 that multiple steel plates 11 are formed, during " mud guiding tube jacking ", even if it is harder to run into soil property on pipe pine mud device 1
Geology (or close clay), can also rely on blade 111 dissection, destroy the harder geology of the soil property (or
The close clay of person), jacking action is smoothed out, stuck phenomenon will not occur.
If the diameter of guide pipe 2 is smaller, when can not directly be connected through a screw thread the guiding connection end 101, can also increase
Add a reducing connector 4, the structure of the reducing connector 4 is integrally conical as shown in Fig. 2, Fig. 2A, and one end is big footpath
End, the other end is miner diameter end, and both ends are equipped with screw thread.
As shown in figure 3, the miner diameter end of reducing connector 4 is connected through a screw thread with the guide pipe 2, bigger diameter end then with it is described
It is oriented to connection end 101 to be connected through a screw thread, realizes the smooth connection of guide pipe 2 and miniature push pipe pine mud device 1.
As can be seen here, the utility model have the advantage that for:
1. after the construction of miniature push pipe pine mud device, the jacking of later stage sewer line is more smooth, reduces pipeline jacking
During required for pressure.
2. being not used before miniature push pipe pine mud device, closely knit cohesive soil is run into, mud guiding tube or head jacking occurred
During because resistance it is excessive, can not jacking situation, after use, no longer run into the above situation.
