Description
Technical Field
The utility model relates to a tubular pile field specifically indicates to have a shape round platform form tubular pile opening pile head of preapring for an unfavorable turn of events.
Background
The tubular pile is a prefabricated engineering pile, is mainly used for improving the bearing capacity of a foundation and a foundation in pile foundation engineering, and is mainly a PHC (prestressed high-strength concrete) tubular pile commonly used at present. When the geological conditions are poor and the bearing capacity of the foundation is small, pile foundations are adopted, one pile is driven into the ground, and the weight of the upper building is transmitted to the soil layer with high bearing capacity of the lower layer through the pile foundations. The center of the tubular pile is arranged into a communicated through hole shape, and the tubular pile is continuously driven into the ground and then enters the sand layer and the cobble layer through the soil layer. Because the frictional force and the resistance that sand bed and goose warm stone layer produced to the tubular pile are far greater than the frictional force and the resistance that the soil layer produced to the tubular pile, when the tubular pile got into sand bed and cobble layer, along with the tubular pile beat more deeply more, the frictional force and the resistance of sand bed and cobble layer to tubular pile inner wall and outer wall were bigger and bigger. So after the tubular pile got into sand bed and cobblestone layer, the pile degree of difficulty promoted greatly, and the degree of depth that the tubular pile was beaten in addition is difficult to reach the anticipated degree of depth, has reduced the produced effect of pile foundation.
To the problem of complaining on, I department has developed "a round platform form tubular pile opening pile head", patent number: CN 201720475040.0. However, in the practical use process, after the tubular pile enters the sand layer and the cobble layer, along with the increase of the stress, after the sealing plate is disconnected from the opening, the top of the pile head is not supported by the sealing plate, the pile head is easy to damage, and meanwhile, the pile head is easy to bend and deform after being damaged, so that the service life is greatly shortened.
The utility model discloses a problem design one kind to foretell prior art existence prevents deformation round platform form tubular pile opening pile head is the utility model discloses the purpose of research.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model provides a shape round platform form tubular pile opening pile head of preapring for an unfavorable turn of events can effectively solve the problem that above-mentioned prior art exists.
The technical scheme of the utility model is that:
the utility model provides an anti-deformation round platform form tubular pile opening pile head, contains opening pile head body, opening pile head body is the round platform form, the center of opening pile head body sets to the through-hole form, the top opening part rigid coupling of opening pile head body has the corresponding position circle of round, the bottom opening part of opening pile head body is provided with the linkage segment that is used for being connected with the cement pile, the position circle has support panel at its opening part rigid coupling, support panel align to grid is provided with a plurality of through-holes, every through-hole all through-hole spot welding be connected with through-hole matched with seals the board.
The positioning ring is welded with a circle of welding spots at equal angles, and the welding spots are connected to the positioning ring and the adjacent sealing plate in a spot welding mode.
The shape of the through holes is honeycomb-shaped.
The utility model has the advantages that:
the utility model discloses the board single in quantity that seals of position circle department before having changed seals the board and drops the condition that the back position circle does not obtain the support, adds cellular support panel at the position circle, and support panel still can be good support between the position circle after sealing the board and breaking away from, reduces the condition that the position circle takes place to damage, warp.

Detailed Description
To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:
referring to fig. 1-3, an anti-deformation round platform-shaped tubular pile opening pile head contains opening pile head body 1, opening pile head body 1 is round platform-shaped, the through-hole form is set to opening pile head body 1's center, opening pile head body 1's top opening part rigid coupling has the corresponding position circle 3 of round, opening pile head body 1's bottom opening part is provided with the linkage segment that is used for being connected with the cement pile, position circle 3 has support panel 5 at its opening part rigid coupling, support panel 5 align to grid is provided with a plurality of through-holes, every through-hole all through welding spot welding 4 be connected with through-hole matched with seal board 2.
The positioning ring 3 is welded with a circle of welding spots 4 at equal angles, and the welding spots 4 are connected to the positioning ring and the adjacent sealing plate 3 in a spot welding mode.
The shape of the through holes is honeycomb-shaped.
When in work, before piling, the utility model is arranged at the head of the tubular pile, the stress is small when the tubular pile is driven into the soil layer, the tubular pile is easy to be driven, the connection between the sealing plate 2 and the positioning ring 3 can not be damaged, after the pipe pile enters the sand layer, along with the increase of the stress, when the stress of the sealing plate 2 reaches 200-400T, the connection between the sealing plate 2 and the positioning ring 3 is destroyed, the stress is gradually increased along with the increase of the depth of the sealing plate entering the sand layer, the welding points 4 of the sealing plate 2 and the positioning ring 3 are disconnected point by point, and finally the sealing plate 2 leaves the opening of the positioning ring 3 and is squeezed into the through hole of the tubular pile by sand, after the sealing plate 2 enters the through hole of the tubular pile, sand and soil gradually enter the through hole of the tubular pile along with the increase of the entering depth of the tubular pile, so that the friction and resistance on the inner side wall of the tubular pile are effectively reduced, and the difficulty of driving the tubular pile into a sand layer and cobblestones can be effectively reduced; simultaneously, because this novel 2 single in quantity of the board that seals of 3 departments of position circle before having changed, the condition that the position circle 3 does not obtain the support after sealing 2 and drop, add honeycomb supporting panel 5 at position circle 3, supporting panel 5 still can be good support between position circle 3 after sealing 2 and break away from, reduce the position circle 3 and take place the condition of damaging, warping.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made within the scope of the claims of the present invention should belong to the scope of the present invention.
