Further, the at least three transverse sleeves are uniformly distributed along the circumferential direction of the cast-in-place pile steel reinforcement framework.

Further, the bottom ends of the longitudinal sleeves are on the same horizontal plane as the transverse sleeves.

Further, the bottom end of the longitudinal sleeve is fixedly connected with the transverse sleeve.

Further, the distance between one end of the transverse sleeve positioned inside the cast-in-place pile steel reinforcement framework and the axis of the cast-in-place pile steel reinforcement framework is larger than the radius of the concrete guide pipe.

Furthermore, sleeve protection steel bars are arranged in the transverse sleeves.

The invention has the beneficial effects that: set up horizontal sleeve pipe through the bottom at bored concrete pile steel reinforcement framework's pile head to set up sleeve pipe protection reinforcing bar in horizontal sleeve pipe, thereby make when getting rid of bored concrete pile head, take out sleeve pipe protection reinforcing bar can obtain at least three with bored concrete pile steel reinforcement framework's the axis vertically bores the hole, and then reach and use manpower sparingly, conveniently separate bored concrete pile head fast, reduce environmental pollution, and protect bored concrete pile steel reinforcement framework's purpose.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Fig. 1 is a schematic structural view of a rapidly separated concrete cast-in-place pile head according to an embodiment of the present invention;

fig. 2 is a top view of a rapidly separated concrete cast-in-place pile head according to an embodiment of the present invention;

in the figure: 1. the cast-in-place pile comprises a cast-in-place pile reinforcement cage, 2 longitudinal reinforcements, 3 longitudinal sleeves, 4 transverse sleeves and 5 sleeve protection reinforcements.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.

As shown in fig. 1-2, the quickly separated concrete cast-in-place pile head according to the embodiment of the present invention includes a cast-in-place pile steel reinforcement framework 1 and concrete, a longitudinal steel reinforcement 2 is disposed at a pile head of the cast-in-place pile steel reinforcement framework 1, a longitudinal sleeve 3 is sleeved on the longitudinal steel reinforcement 2, four transverse sleeves 4 are disposed at a bottom of the pile head of the cast-in-place pile steel reinforcement framework 1, the transverse sleeves 4 are perpendicular to the longitudinal sleeve 3, an axis of each transverse sleeve 4 is distributed along a radial direction of a bottom surface of the pile head of the cast-in-place pile steel reinforcement framework 1, one end of each transverse sleeve 4 is located inside the cast-in-place pile steel reinforcement framework 1, and the other end of each transverse sleeve 4 is located outside the cast-in-. The four transverse sleeves 4 are uniformly distributed along the circumferential direction of the cast-in-place pile steel reinforcement framework 1.

The bottom end of the longitudinal sleeve 3 and the transverse sleeve 4 are on the same horizontal plane, and the bottom end of the longitudinal sleeve 3 is fixedly connected with the transverse sleeve 4. The distance between one end of the transverse sleeve 4 positioned inside the cast-in-place pile steel reinforcement framework 1 and the axis of the cast-in-place pile steel reinforcement framework 1 is slightly larger than the radius of the concrete guide pipe. And a sleeve protective steel bar 5 is arranged in the transverse sleeve 4.

In order to facilitate understanding of the above-described technical aspects of the present invention, the above-described technical aspects of the present invention will be described in detail below in terms of specific usage.

Before placing bored concrete pile framework of steel reinforcement 1, sheathe in longitudinal sleeve pipe 3 on longitudinal reinforcement 2, install horizontal sleeve pipe 4 in the bottom of longitudinal sleeve pipe 3 to install sleeve pipe protection reinforcing bar 5 in horizontal sleeve pipe 4, the both ends of shutoff longitudinal sleeve pipe 3 and horizontal sleeve pipe 4 prevent that grout from getting into the sleeve pipe. Then the cast-in-place pile steel reinforcement framework 1 is placed according to the conventional technology and concrete is poured. When the concrete strength meets the requirement, digging out the pile head section to be chiseled, cutting a groove at the bottom end of the pile head along the circumferential direction, fixing a reinforcing steel rope for hoisting on the transverse sleeve 4 and the sleeve protective reinforcing steel bar 5, and hoisting after fixing the reinforcing steel rope to separate the pile head part from the longitudinal reinforcing steel bar 2 of the pile head.

In summary, according to the technical scheme of the invention, the transverse casing is arranged at the bottom of the pile head of the cast-in-place pile reinforcement cage, and the casing protection reinforcement is arranged in the transverse casing, so that when the pile head of the cast-in-place pile is removed, at least three drill holes perpendicular to the axis of the cast-in-place pile reinforcement cage can be obtained by removing the casing protection reinforcement, and the purposes of saving manpower, conveniently and quickly separating the pile head of the cast-in-place pile, reducing noise and dust pollution, and protecting the cast-in-place pile reinforcement cage are achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
