[0002] MPP power pipes, made primarily from modified polypropylene, exhibit excellent properties such as resistance to high temperatures and external pressure. Trenchless MPP power pipes eliminate the need for extensive dredging, excavation, or road surface damage, making them particularly suitable for laying pipes and cables in areas such as roads, railways, buildings, and under riverbeds. Compared to traditional trenching and pipe laying, trenchless power pipe projects are more environmentally friendly, avoiding the dust and traffic congestion associated with traditional construction. They can also be laid in areas where excavation is impractical. Connections are often made through hot-melt welding, and supporting structures with restraint functions are required to neatly organize the power pipes.

[0006] By adopting the above technical solution, two sets of upper and lower plates that cooperate with each other are used to lock the outside of the power pipe on both sides of the weld, and then a locking bolt is used to lock it between the two sides of the lower plates, which can ensure that the power pipe is tightly locked after welding and ensure a firm connection.

[0007] Optionally, a groove is provided on the surface of the lower plate at the through opening, and the diameter of the groove is larger than the diameter of the nut and the screw cap of the locking bolt.

[0008] By adopting the above technical solution, when the nut is tightened on the outer ring of the bolt, the nut cap and the nut can be restrained in the groove to avoid slipping.

[0009] Optionally, rubber pads are fixed to the inner surfaces of the lower tube groove and the upper tube groove, and the rubber pads are fixed to the surfaces of the lower tube groove and the upper tube groove by fitting.

[0010] By adopting the above technical solution, when the MMP power pipe is placed in the upper pipe groove and the lower pipe groove, the rubber pad contacts the surface thereof to achieve the purpose of anti-slip locking.

[0022] See also Figure 1-4 The utility model provides a technical solution: an MPP power pipe connection auxiliary mechanism, comprising a lower plate 1, an upper plate 2 and a locking bolt 5, wherein the upper plate 2 is placed in a plate groove 11 arranged above the lower plate 1, and the size of the plate groove 11 is slightly larger than the size of the upper plate 2, and a plurality of lower pipe grooves 12 are evenly opened on the upper surface of the upper plate 2 at the plate groove 11, and a plurality of upper pipe grooves 21 are evenly opened on the lower surface of the upper plate 2, and the upper pipe grooves 21 and the lower pipe grooves 12 are the same size, and the upper pipe grooves 21 and the lower pipe grooves 12 are aligned with each other. When in use, the MMP power pipe 6 is placed between the lower pipe groove 12 and the upper pipe groove 21, and then a plurality of bolts 4 are vertically penetrated through the surface of the upper plate 2, and the surface of the upper plate 2 at the bolt 4 is provided with a through hole that passes through the upper and lower parts, and the bolt 4 passes through the upper plate 2 through the through hole, and the surface of the lower plate 1 just below the bolt 4 is provided with a screw hole 14, and the bottom of the bolt 4 is screwed into the screw hole 14 on the surface of the lower plate 1 to lock the upper plate 2, so that the power pipe 6 can be clamped and locked through the upper pipe groove 21 and the lower pipe groove 12.

[0023] In order to achieve the purpose of firm and anti-slip locking, rubber pads 3 are fixed on the inner surfaces of the lower tube groove 12 and the upper tube groove 21. The rubber pads 3 are fixed to the surfaces of the lower tube groove 12 and the upper tube groove 21 by fitting. After the upper plate 2 and the lower plate 1 are locked, the rubber pads 3 contact the outer surface of the power tube 6, which can achieve a better anti-slip locking effect.

[0024] On both side surfaces of the lower plate 1, there are through-openings 13 that pass through the outer side and the outside, and the diameter of the locking bolt 5 is smaller than the inner diameter of the through-opening 13. The end of the locking bolt 5 is connected to the nut 51 by screwing. When in use, two sets of upper plates 2 and lower plates 1 are used to cooperate with each other and placed on both sides of the weld of the power pipe 6 to restrain and lock the power pipe 6. Then, the locking bolt 5 is clamped from the side into the through-openings 13 on the two sides of the lower plate 1 on both sides of the weld, and the nut 51 is tightened to lock the lower plate 1 and the upper plate 2 to the weld position to ensure the firmness and stability of the connection.

[0025] A groove 131 is provided on the surface of the lower plate 1 at the through-hole 13. The diameter of the groove 131 is larger than the diameter of the nut 51 and the cap of the locking bolt 5. When the nut 51 is tightened, the nut 51 and the cap of the locking bolt 5 are in contact with the groove 131, thereby preventing slipping.

[0026] When in use, unscrew the bolts 4 to remove the upper plate 2 first, lay the lower plate 1 at the bottom first, place the power pipe 6 in different lower pipe grooves 12, and keep the ends of the power pipe 6 aligned, then place the upper plate 2 on top, and place the upper part of the power pipe 6 in the lower pipe groove 12 below the upper plate 2, and place the upper plate 2 in the plate groove 11, then make the bolts 4 pass through the upper plate 2 and screw them into the screw holes 14 of the lower plate 1, tighten and lock the upper plate 2 and the lower plate 1, clamp and lock the power pipe 6 to keep the ports aligned, then align the power pipe 6 to be connected with the end of the locked power pipe 6, and then melt it by hot melting.
