Detailed Description

The invention will be described in detail with reference to the following drawings and specific embodiments:

as shown in fig. 1 to 4

A prefabricated concrete hollow pile comprises a pile body 1 and a pile head 2, wherein the pile head 2 is positioned at the bottom of the pile body 1, the pile body 1 and the pile head 2 are integrated, the outer wall of the pile body 1 is smoothly connected with the outer wall of the pile head 2, the prefabricated concrete hollow pile also comprises a main rib 3 arranged in the pile body 1 and an auxiliary rib 4 surrounding the main rib 3, the auxiliary rib 4 transversely surrounds the main rib 3, the distance between the adjacent auxiliary ribs 4 on the upper layer and the lower layer is equal, the prefabricated concrete hollow pile also comprises an alarm device 5, the alarm device 5 comprises a trigger 51, wire 52 and alarm lamp 53, trigger 51 set up in pile head 2, and trigger 51 is disposable, and trigger 51 is extruded or destroys and will send information to alarm lamp 53 through wire 52, and alarm lamp 53 sets up on the lateral wall of pile body 1, and alarm lamp 53 is close to the one end at pile body 1 top, and wire 52 passes pile body 1 and is connected with alarm lamp 53, and wire 52 imbeds in the pile head 2 and is connected with trigger 51. When pile sinking construction is carried out, pile head 2 and the mutual extrusion of ground are collided, if pile head 2 is extruded deformation or is destroyed, trigger 51 will be triggered, signals are sent out, transmit alarm lamp 53 through wire 52, alarm lamp 53 carries out the warning suggestion to transmit the directly perceived transmission of impaired volume of pile head 2 for constructor.

The pile body 1 is a hexagonal column. The outer surface area of the hexagonal pile under the same section of concrete is larger than that of the tubular pile, and the repose angle between the periphery of the appearance of the hexagonal pile body 1 and the soil in a soil layer is larger than that of a round friction factor, so that the hexagonal pile body 1 can obtain larger bearing capacity under the same geological conditions.

Three vertical through holes 11 are formed in the pile body 1. Through-hole 11 evenly sets up in pile body 1 along axial direction to practice thrift the preparation material, reduced the cost of manufacture, guaranteed hollow pile intensity moreover, avoided single through-hole 11 to destroy the phenomenon emergence of pile body 1 because of intensity is not enough.

The top of pile body 1 still is equipped with end board 7, end board 7 includes three cylinder 61 and bottom plate 62, cylinder 61 inserts in the through-hole 11, cylinder 61 with through-hole 11 clearance fit. End board 7 of pile body 1 is a stereoplasm steel block, and end board 7 can be dismantled with pile body 1 and be connected, during pile sinking, strikes on end board 7 to reduce the loss to hollow pile, further promotion hollow pile's performance, end board 7 can also be torn open used repeatedly moreover, saves the cost.

The cross section of the bottom plate 62 is the same as that of the pile body 1, and the shape of the column body 61 is the same as that of the through hole 11. The cross section of the bottom plate 62 is the same as or slightly larger than that of the pile body 1, so that the pile body 1 is completely covered, and the stress is more uniform during pile sinking.

And a reinforcing rib 7 is further arranged between the main rib 3 and the rectangular frame formed by the auxiliary ribs 4, and the reinforcing rib 7, the main rib 3 and the auxiliary ribs 4 are welded and fixed. The reinforcing rib 7 divides the rectangular frame formed by connecting the main rib 3 and the auxiliary rib 4 into two right-angled triangles, and the triangular frame has stability, so that the overall strength of the hollow pile is further enhanced.

The pointed part of pile head 2 is equipped with stereoplasm drill bit 8, and the intensity of drill bit 8 is higher than the column cap to can protect pile head 2 by the harm, and then improve the wholeness ability of hollow pile, improve the efficiency of construction.

The utility model discloses a use method as follows: and (3) inserting the end plate 7 into the through hole 11, vertically suspending the hollow pile, placing the hollow pile in a prefabricated foundation hole, knocking the pile body 1, or performing other pile sinking modes, and after the hollow pile is sunk to a preset position, detaching the end plate 7 for performing next pile sinking.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will understand that the present invention can be modified or replaced with other embodiments without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims. The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
