Description of reference numerals: the steel pipe pile comprises a steel pipe pile 1, a connecting plate 2, a semicircular ring 3, a mounting plate 4, a first bolt 5, a ball 6, a connecting block 7, a second bolt 8, a folded edge 9, a third bolt 10, a through hole 11, a guardrail 12, a life buoy 13, a connecting rod 14 and an inserting rod 15.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1, a steel trestle pile foundation unit includes two vertical steel-pipe piles 1, still includes two circular shape sliding sleeves and a connecting plate 2, and two sliding sleeves overlap respectively and establish on two steel-pipe piles 1, and every sliding sleeve all includes two semicircle rings 3 that the concatenation formula links together, every of sliding sleeve semicircle ring 3's both ends all are fixed with connecting block 7, and two connecting blocks 7 of 3 tip concatenation departments of two semicircle rings are connected through second bolt 8.

As shown in fig. 1, one of the semicircular rings 3 on each sliding sleeve is fixed with one mounting plate 4, the connecting plate 2 is detachably connected between the two mounting plates 4, two ends of the connecting plate 2 are respectively provided with a folded edge 9 which is bent towards the same side of the connecting plate 2, the two folded edges 9 respectively correspond to the two mounting plates 4, the folded edges 9 are connected with the corresponding mounting plates 4 through third bolts 10, and the connecting plate 2 is located at the same side of the two steel pipe piles 1.

As shown in fig. 1, one semicircular ring 3 of each sliding sleeve is in threaded connection with a first bolt 5 which can be screwed into the corresponding steel pipe pile 1 to abut against the corresponding steel pipe pile 1, the first bolt 5 is close to the connecting plate 2, and the sliding sleeve is directly locked on the corresponding steel pipe pile 1 by means of the first bolt 5.

As shown in fig. 1, a plurality of balls 6 distributed along the direction of the semicircular ring 3 are embedded in the inner side of each semicircular ring 3, the plurality of balls 6 are abutted against the corresponding side wall of the steel pipe pile 1, and the sliding sleeve slides by rolling of the balls 6, so that the friction force generated between the sliding sleeve and the steel pipe pile 1 in the sliding process can be effectively reduced.

As shown in figure 1, a plurality of through holes 11 are formed in the connecting plate 2, on one hand, the dead weight of the connecting plate 2 can be reduced, materials are saved, on the other hand, steel trestle construction is often carried out above the water surface, constructors inevitably bring certain water onto the connecting plate 2, therefore the connecting plate 2 is wet and smooth, potential safety hazards are generated, the through holes 11 are formed, water on the connecting plate 2 can be effectively discharged, and accordingly construction safety is guaranteed. Guard rails 12 are fixed on two sides of the connecting plate 2, and the guard rails 12 are arranged to guarantee safety of constructors.

As shown in fig. 1, a life buoy 13 is arranged on the connecting plate 2, a connecting rod 14 is fixed on the connecting plate 2, an inserting rod 15 is fixed on the rod connecting rod 14, and the inserting rod 15 is inserted in a central hole of the life buoy 13.

The steel trestle construction generally is on the surface of water, and constructor has the hidden danger of falling into water, consequently sets up life buoy 13, after taking place the accident of falling into water, constructor can in time throw life buoy 13 on the surface of water near the personnel of falling into water to further improve the ability of saving oneself.

As shown in fig. 1, the plate surface of the connecting plate 2 is perpendicular to the length direction of the two steel pipe piles 1, and this way enables a constructor to stand on the connecting plate 2 more firmly for construction, thereby further ensuring the safety of the constructor.

The working principle is as follows: as shown in fig. 1, a construction worker drives two steel pipe piles 1 into a river bottom to insert the bottom ends of the two steel pipe piles 1 into the river bottom by a certain depth.

Later constructor with the help of the boat, the boat floats on the surface of water, and constructor establishes two sliding sleeve covers respectively and installs on two steel-pipe pile 1, and concrete operation is to splice two semicircle rings 3 of every sliding sleeve in the periphery of steel-pipe pile 1 respectively, later carries out fixed connection through two adjacent connecting blocks 7 after the second bolt 8 will splice, and the sliding sleeve concatenation is accomplished this moment.

And then the constructor installs the connecting plate 2 between the two mounting plates 4, namely fixedly connecting the folded edge 9 and the mounting plate 4 corresponding to the folded edge 9 by using a third bolt 10, wherein the two sliding sleeves and the connecting plate 2 form a whole at the moment, and the two sliding sleeves can drive the connecting plate 2 to vertically slide along the steel pipe pile 1.

Then the constructor lifts by crane the machines with the help of lifting by crane, lifts by crane machines with sliding sleeve and connecting plate 2 upwards along steel-pipe pile 1, and until lifting by crane connecting plate 2 to being close to the top of steel-pipe pile 1, constructor precession first bolt 5 this moment to make the sliding sleeve lock on corresponding steel-pipe pile 1.

And finally, a constructor can stand on the connecting plate 2 and weld the I-shaped steel beam on the top of the steel pipe pile 1.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
