When first mounting flange 2 is connected with prefabricated pile body 1, the end of prefabricated pile body 1 embeds in the cavity 21a that annular rib 21 surrounds, and is fixed together with prefabricated pile body 1 by the first mounting flange 2 by the cooperation of main muscle on prefabricated pile body 1 and the first connecting hole 22 simultaneously.
First mounting flange 2 can also be adopted as slab construction.
Method of attachment: step one, lower joint stake is sink to the position of overhead 0.8 to 1.2m, suspends pile sinking, lower joint stake is fixed；Step 2, upper joint stake is winched to straightening after above lower joint stake, under slowly, put joint stake, rotate the stake of upper joint simultaneously and makes the first suitable mounting flange 2 and the second mounting flange 3 screw up；Step 3, repetition step one, to two, complete the connection of whole pile body.
Embodiment two, as shown in Fig. 5 to Fig. 8,
Prefabricated pile in the present embodiment is similar to the prefabricated pile structure in embodiment one, institute the difference is that, in the present embodiment, first mounting flange 2 adopts with described second mounting flange 3 and is radially located by connecting, the outer periphery of the first mounting flange 2 offers the first fixing hole 5a, annular retaining ring 31 radially offers the second fixing hole 5b on the correspondence position of described first fixing hole 5a, second fixing hole 5b runs through described annular retaining ring 31, is provided with fixture 6 in the first corresponding fixing hole 5a and the second fixing hole 5b.
Fixture 6 ecto-entad is radially placed in the first fixing hole 5a and the second fixing hole 5b of alignment, and after fixing, a part for fixture 6 is positioned at the first fixing hole 5a, and another part is positioned at the second fixing hole 5b.
In embodiment, the first fixing hole 5a and the second fixing hole 5b is unthreaded hole, and fixture 6 is pin.
The first fixing hole 5a and the second fixing hole 5b can also be adopted to be screwed hole, and fixture 6 is bolt, with bolts, connects more reliable.
Method of attachment: step one, lower joint stake is sink to the position of overhead 0.8 to 1.2m, suspends pile sinking, lower joint stake is fixed；Step 2, upper joint stake is winched to straightening after above lower joint stake, joint stake is put under slowly, make the first corresponding with on the first mounting flange 2 for the second fixing hole 5b fixing hole 5a on the second mounting flange 3 align, then fixture 6 is inserted in the second fixing hole 5b alignd and the first fixing hole 5a；Step 3, repetition step one, to two, complete the connection of whole pile body.
Embodiment three, as shown in Fig. 9 to Figure 14,
Prefabricated pile in the present embodiment is similar to the prefabricated pile structure in embodiment one, institute the difference is that, in the present embodiment, first mounting flange 2 adopts snap ring 8 to be connected with described second mounting flange 3, the outer periphery of the first mounting flange 2 offers the first annular groove 7a, radially offering the second annular groove 7b on the correspondence position of described first annular groove 7a on annular retaining ring 31, snap ring 8 is placed in the snap ring intracavity being made up of the first annular groove 7a and the second annular groove 7b.
In embodiment, snap ring 8 is loop configuration, and this loop configuration is provided with breach 8a.Owing to being provided with breach 8a, the snap ring 8 of loop configuration is made to have elasticity；When connecting, first breach 8a is expanded so that snap ring 8 can be inserted in the first mounting flange 2, and enter in the first annular groove 7a, then inward compression snap ring 8, make snap ring 8 completely in the first annular groove 7a, then the second mounting flange 3 is connected with the first mounting flange 2；When the second mounting flange 3 is connected with the first mounting flange 2 and to put in place, namely when the second annular groove 7b and the first annular groove 7a aligns, snap ring 8 naturally extends out thus being placed in the snap ring intracavity being made up of the first annular groove 7a and the second annular groove 7b due to natural resiliency, at this moment, a part for snap ring 8 is positioned at the first annular groove 7a, and another part is positioned at the second annular groove 7b, thus completing to connect.
Owing to prefabricated pile is relatively large in diameter, above-mentioned snap ring 8 manufacture requirements is high, and manufacturing cost is big.Snap ring 8 can also adopt the loop configuration that the clasp piece 81 of arcuate structure is constituted, when this snap ring 8 is installed, first each clasp piece 81 is put into the second annular groove 7b of the second mounting flange 3, after the second mounting flange 3 is inserted in the first suitable mounting flange 2, by the through hole offered in the second annular groove 7b periphery in advance, push away in clasp piece 81 phase with screw rod or other instrument, make in the first annular groove 7a being partly into the first mounting flange 2 of clasp piece 81, after completing, a part for snap ring 8 is positioned at the first annular groove 7a, another part in the second annular groove 7b thus the connection completed between the first mounting flange 2 and the second mounting flange 3.
Method of attachment: step one, lower joint stake is sink to the position of overhead 0.8 to 1.2m, suspends pile sinking, lower joint stake is fixed；Step 2, upper joint stake is winched to straightening after above lower joint stake, put joint stake under slowly, complete the connection between the first mounting flange 2 and the second mounting flange 3 by snap ring 8；Step 3, repetition step one, to two, complete the connection of whole pile body.
The prefabricated pile of the present invention is by arranging the two ends that the first mounting flange 2 and the second mounting flange 3 Formation cross-section are " convex " character form structure and concave structure respectively, and by the mechanical connection between suitable the first mounting flange 2 and the second mounting flange 3, adopt threaded, be radially located by connecting or snap ring connects and is capable of on-the-spot quickly pile extension, be greatly improved efficiency of construction；Without the need for welding at the scene, reduce atmospheric pollution and the electric welding body harm to operator.
Highly preferred embodiment of the present invention is elucidated with, those of ordinary skill in the art the various changes made or remodeling are all without departing from the scope of the present invention.
