[0002] Pipe piles are a type of prefabricated concrete component, usually used as the base material for building foundations. They are made by mixing raw materials such as sand, cement, steel bars and additives, and then through processes such as mud core pressurization. Pipe piles use the support and friction of the soil to bear the weight and load of structures such as buildings or bridges. It is a common foundation reinforcement technology. It is widely used in infrastructure such as factories, airports, roads, railways, ports, etc.

[0003] In the process of pipe piles, after the raw materials are mixed and stirred, the mixed mud is distributed to the hoppers of each grouting machine through the distributor through the distribution equipment. After the steel cage is tensioned, the grouting machine injects the mud into the pipe pile mold through the pipeline to fill the steel cage. The end of the steel cage is equipped with a connecting plate; the traditional tensioning connection equipment and the connecting plate at the end of the steel cage are fixed by bolts. This connection structure results in a long disassembly process after the tensioning bolts at the end of the steel cage are used, which affects the production progress of the equipment.

The plug 1.3 penetrates from the circular hole 3.2 and moves to both sides. After the diameter of the plug 1.3 is larger than the width of the plug 1.3 on both sides, the main reinforcement 1.1 cannot exit the anti-deflection sleeve 3, forming a connection structure.

[0022] like Figure 2-5 As shown, the outer end of the anti-deviation sleeve 3 is fixed with a bolt 13; the connecting plate 2 is threadedly fixed to the anti-deviation sleeve 3 to form a fixed end of the pipe pile. The fixed end is the part that is filled with mud together with the steel cage 1, so the bolts of this part are not removed and do not affect the disassembly progress. A tensioning plate 4 is also provided on the outer side of the connecting plate 2 at one end of the main reinforcement 1.1; the tensioning plate 4 needs to be removed, and this part is the main connecting structure that affects the progress; tensioning bolts 5 are fixed on the surface of the tensioning plate 4; the tensioning bolts 5 are connected to the tensioning machine.

When tensioned, the structure forms an effective connection. Two limiting collars 6 are butt-jointedly sleeved on the outside of the tensioning plate 4 and the connecting plate 2 and are located in the pipe pile mold 10; after the pipe pile mold 10 is closed, the limiting collars 6 are pressed.

If the fixing method is not described separately in the above, welding or threaded fastening is used by common technical means of technicians in the industry.

[0024] Here’s how it works:

[0025] First, place a half ring of the limiting collar 6 on one end of the pile mold 10 that is tensioned; first, set the positioning plates 7 on both ends of the main reinforcement 1.1, and the positioning plates 7 with connecting screws 9 pass through the hole sleeves 8 of the other positioning plates 7; then, sequentially set the anti-deflection sleeve 3 and the connecting plate 2; the connecting plate 2 and the anti-deflection sleeve 3 are threadedly fixed; the connecting screw 9 passes through the middle of the connecting plate 2; the end nut 11 of the connecting screw 9 is fixed on the outside of the connecting plate 2; after the anti-deflection sleeve 3, the connecting plate 2 and the main reinforcement 1.1 are connected, they are placed in the pile mold 10; the placement position corresponds to the limiting collar 6; then the tensioning plate 4 is placed; and finally, the other half of the limiting collar 6 is closed.
