Drawings
Figure 1 is the utility model provides a high stability civil engineering antidetonation composite pile's structural schematic.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Examples
A high stability civil engineering antidetonation combination pile, as shown with reference to figure 1, includes:
a pile body 1 is arranged;
the upper pile body 2 is inserted into the lower pile body 1, the end part of the upper pile body 2, which is positioned in the lower pile body 1, is connected with a sphere 3, a groove 11 for nesting the sphere 3 is arranged in the lower pile body 1, and a damping layer 23 is filled between the inner wall of the groove 11 and the sphere 3;
the upper pile body 2 is sleeved with a ring body 21, and a plurality of first high-strength springs 22 are arranged between the ring body 21 and the lower pile body 1 along the circumferential direction.
For this reason, the antidetonation composite pile that this embodiment provided is through last, two pile body group become down, it is internal that pile body pegs graft in pile body down on it, there is the spheroid through the end connection that lies in pile body down at last pile body, be equipped with nested spheroidal recess in pile body down, it has the damping layer to fill between recess inner wall and the spheroid again, this pile body is under seismic effect, no matter receive horizontal load, still receive vertical load, all can not part two piles, pile body receives under the effect of horizontal force simultaneously, use nested spheroid as the center, the recess of pile body rotates on the spheroid down, thereby avoid the bending damage of whole stake, can effectually promote the overall stability of pile body.
In order to realize the stability between the bottom of the ball body and the groove, a plurality of small ball bodies 32 are arranged between the bottom of the ball body 3 and the inner wall of the groove 11, the upper half part of each small ball body 32 is embedded in the bottom of the ball body 3, and the lower half part of each small ball body 32 is embedded in the inner wall of the groove 11. Therefore, the small spheres 32 are used for positioning the sphere 3, so that the sliding between the sphere and the groove caused by slight vibration is avoided, and the stability between the bottom of the sphere and the groove is improved.
Under the action of horizontal force, in order to slow down the rotation speed of the groove of the lower pile body on the ball body, a plurality of second high-strength springs 31 are arranged between the upper part and the lower part of the ball body 3 and the inner wall of the groove 11 along the circumferential direction, namely, a circle of vertical first vertical surfaces are respectively arranged on the upper part and the lower part of the sphere along the circumferential direction, a circle of vertical second vertical surfaces are respectively arranged on the upper part and the lower part of the groove along the circumferential direction, a plurality of second high-tensile springs 31 are provided at equal intervals between each of the first and second vertical surfaces, and, for this purpose, when the lower pile body horizontally swings under the action of horizontal force, the second high-strength spring hinders the horizontal swing of the lower pile body, so that the rotation speed of the groove of the lower pile body on the ball body is slowed down, thereby avoiding the loss of the supporting layer at the bottom of the upper pile body and further effectively improving the stability between the upper pile body and the lower pile body.
