Description

Building foundation pile

Technical Field

The invention relates to the field of buildings, in particular to a building foundation pile.

Background

The building base is used for being driven into the building ground, cement pouring is carried out on the interior of the building base, and a supporting pile body is formed after the cement is dried and solidified. The existing building pile body is generally a hollow structure, the hollow structure is formed by splicing more than one base plate, and then cement is poured into a cavity formed by splicing the base plates.

When the base plates are driven into the ground, the base plates are knocked on the base plates by the pile drivers, so that the service lives of the base plates are shortened due to long-term knocking of the pile drivers, and the service lives of the base plates are shortened due to repeated use of the pile drivers.

Furthermore, after the cement is poured, in order to increase the strength of the cement pile, some metal pieces are inserted into the poured cement, so that the use strength in the later period is increased, and therefore, a step of driving the metal pieces is required after the pouring is finished.

Finally, because the cement poured is not uniformly stirred, if the cement is directly poured into the hollow package, the later cement strength is affected.

Detailed Description

As shown in fig. 1-4, the building foundation pile comprises a frame-shaped hollow foundation pile formed by splicing four base plates 9, a square pouring cavity is arranged in the middle of the foundation pile, the bottom of each base plate 9 is detachably provided with a bottom plate 6, the bottom plates 6 can be damaged, the inner side ends of the four base plates 9 are fixedly provided with a hollow plate 4, the hollow plate 4 is internally provided with a hollow cavity 15, one side surface of the hollow plate 4, far away from the base plate 9, is provided with more than one feeding and discharging small hole 8, each feeding and discharging small hole 8 is communicated with the hollow cavity 15 in the hollow plate 4, a square sealing plate 2 is arranged in the square pouring cavity, the bottom of the sealing plate 2 is provided with a conical part 3, the conical part 3 is pressed to the bottom to damage the bottom plate 6 and is inserted into soil, a metal reinforcing rod 1 is fixedly welded at the top of the sealing plate 2, and a hammering part 12 is arranged at the top of the metal reinforcing rod 1.

In this embodiment, a fixed shaft sleeve is disposed at the bottom of the hammering portion, an external thread section is disposed at the top of the metal reinforcing rod 1, and the metal reinforcing rod 1 is installed in a threaded hole of the fixed shaft sleeve through the external thread section at the top.

In this embodiment, the bottom of the hollow plate 4 is provided with a convex portion 7 opposite to one end of the base plate, a groove is formed on the inner wall of the base plate opposite to the convex portion 7, and the hollow plate 4 is buckled in the groove through the convex portion 7 at the bottom for positioning.

In this embodiment, one side of the top of the hollow plate 4 opposite to the substrate is provided with a locking screw hole, a locking screw 11 is screwed into the outside of the substrate opposite to the locking screw hole, and the locking screw 11 penetrates through the substrate 9 and is locked in the locking screw hole.

The bottom plate 6 is made of a metal sheet, the outer side end of the bottom plate 6 is locked by a screw rod 5 penetrating through the upper end of the base plate, and the screw rod 5 is screwed in from the top of the base plate 9 and is screwed out from the bottom of the base plate and locked into the bottom plate 6. The metal sheet can be damaged by the hammering part at the bottom of the metal reinforcing rod, one damaged end of the hammering part can be inserted into soil, and after the hammering part damages the bottom plate, the upper end face of the hammering part can be lowered to the lower end of the bottom plate; when the closing plate receives pressure drop, the inside cement of pouring cavity can be continuous passes the business turn over material aperture of bottom and finally discharges from the business turn over material aperture that is located the closing plate top under the extrusion force, along with continuous pushing down, the cement that is located the bottom can be continuous removes to the top of closing plate, push down to the bottommost back when the monoblock closing plate, all cement just can remove to the top of closing plate, whole watering process alright completion this moment, and when all cement removed to the top of closing plate, whole root metal stiffener just can be buried in cement 13 this moment, need not subsequent action of burying underground, unusual convenience, whole process has been simplified.

When piling, the whole device is placed at a position to be driven, cement 13 is poured in a pouring cavity, then a sealing plate is installed, a pile driver directly strikes the hammering part to enable the metal reinforcing rod to drive the sealing plate to descend, and the cement enters each feeding and discharging small hole to be stressed, so that the striking force of the pile driver can enable the cement to have resistance when entering the feeding and discharging small holes, the whole foundation pile descends and is driven into soil by using the resistance, after the driving is completed, the locking screws are loosened, because the upper end face of the sealing plate is lower than the upper end face of the bottom plate after the sealing plate is driven, all the hollow plates can be taken out after the locking screws are taken out, the cement is waited to be dried, after the cement is dried, the screw rods are taken out, a layer of isolating layer can be arranged on the contact face of the inner side end of the base plate and the hollow plate, the base plate is convenient to take out, and after the screw rods on the base plate, the base plate can be taken out upwards while the middle concrete pile is remained.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
