Each baffle 17 covers the corresponding grout outlet 10, and a driving component for driving each baffle 17 to move up and down is arranged in each pile body 1 and is two threaded rods 7. Two threaded rods 7 are located the both sides in the pile body 1 respectively and all set up along the length direction of pile body 1, and the one end that two threaded rods 7 are close to second mounting panel 212 is connected with the both sides bearing of the second mounting panel 212 of mounting bracket 21 respectively, all seted up threaded hole 23 on each baffle 17, threaded rod 7 run through in proper order corresponding threaded hole 23 on the three baffle 17 and with threaded hole 23 threaded connection. The threaded rod 7 is rotated to enable the baffle 17 on the same side to move up and down simultaneously, so that the grout outlet 10 is opened, a constructor can pour concrete grout into the pile body 1, the concrete grout can flow into a concrete layer through the grout outlet 10, and the foundation pile is formed after the concrete grout is condensed.
In addition, for making baffle 17 be difficult for rotating along with threaded rod 7 at the pivoted in-process of threaded rod 7, two inside walls of pile body 1 all weld and have two direction sand grips 9, in this embodiment, the cross section of each direction sand grip 9 all is the T shape setting, and two direction sand grips 9 are located the both sides of the three grout outlet 10 of homonymy respectively. Each guide convex strip 9 is arranged along the length direction of the pile body 1, each baffle 17 is provided with a guide groove 16 corresponding to the guide convex strip 9, each guide groove 16 penetrates through the baffle 17 along the width direction, and each guide convex strip 9 is matched with the corresponding guide groove 16 in a sliding mode. Meanwhile, the inner side wall of the pile body 1 is provided with a plurality of limiting convex strips 19 which are in one-to-one correspondence with the grout outlets 10, each limiting convex strip 19 is welded at one end, far away from the end 2, of the corresponding grout outlet 10 and is located between the two guiding convex strips 9, and each limiting convex strip 19 is arranged along the length direction of the grout outlet 10. When the baffle 17 is moving upwards under the drive of the rotation of the threaded rod 7, the grout outlet 10 is opened, at the moment, one end of the baffle 17 far away from the end head 2 is abutted to the limit convex strip 19, so that the constructor can confirm that the grout outlet 10 is completely opened on the ground. For the convenience of rotating threaded rod 7, threaded rod 7 keeps away from the one end of mounting bracket 21 and can dismantle and be connected with handle 8, and is preferred, and handle 8 is L shape setting, and threaded rod 7 keeps away from the one end welding of mounting bracket 21 has inserted block 20, and the jack 18 that corresponds with inserted block 20 is seted up to the one end of handle 8, and inserted block 20 all is regular hexagon setting with the cross section of jack 18, and inserted block 20 and jack 18 are pegged graft the cooperation. In addition, the magnet blocks 13 which attract each other are adhered to one end of the insert block 20 inserted into the jack 18 and the bottom of the jack 18, so that the insert block 20 is not easy to be separated from the bottom of the jack 18, and the stability between the insert block 20 and the jack 18 is enhanced.
The implementation principle of the embodiment is as follows: during construction, firstly, dig the hole in the soil layer, end 2 patchhole in, and drive the foundation pile into the hole, utilize bolt 11 with protruding edge 6 fixed subaerial, add push rod 12 in pile body 1, add branch 3 on push rod 12, make two push rod 12 move back to back through promoting two push rod 12, branch 3 stretches out pile body 1 and inserts in the soil layer under the promotion of push rod 12, rotation threaded rod 7 makes baffle 17 rebound, until baffle 17 contradicts in spacing sand grip 19, grout outlet 10 is opened, pour the concrete thick liquid into pile body 1, the concrete thick liquid flows out to the soil layer through grout outlet 10, after the concrete thick liquid condenses in order to form the foundation pile, so reinforcing the fastness of being connected between foundation pile and the soil layer.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
