Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following 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.

The application of the principles of the present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1 to 5, a pile foundation anchoring device for sand soil slide-resistant pile construction includes anchoring steel bar 1 and mechanical anchoring piece 2, anchoring thread 101 is provided at the bottom end of anchoring steel bar 1, mechanical anchoring piece 2 includes anchoring screw 201, anchoring steel bar 1 is fixedly connected with mechanical anchoring piece 2 through anchoring thread 101 and anchoring screw 201 of mechanical anchoring piece 2, and anchoring device 3 is provided at the outer side of mechanical anchoring piece 2. Screwing groove 305 has been seted up to 3 upper surface one sides of anchor equipment, 3 lateral parts of anchor equipment have still been seted up shutoff groove 301 near screwing groove 305 notch position department, there is plugging block 302 shutoff groove 301 inboard through torsional spring and pivot swing joint, anchor screw 201 is cup jointed with screwing groove 305 and moving about, plugging block 302 can carry out the horizontal rotation. The bottom end of the anchoring screw 201 is further provided with a screwing big block 203, the bottom end of the screwing groove 305 is further provided with a screwing big groove 306, and the screwing big block 203 and the screwing big groove 306 are movably sleeved so as to be screwed better. The anchoring device 3 located at the adjacent side of the tightening groove 305 is further provided with a pushing groove 303, and a pushing block 304 is movably connected inside the pushing groove 303. Through the arrangement of the pushing block 304, the pushing block 304 is pulled out, so that the mechanical anchor 2 is more labor-saving to tighten. The ratio of the length of the diagonal line at the bottom end of the tightening block 203 to the length of the diagonal line of the anchoring screw 201 is four to one, and the tightening block 203 and the anchoring screw 201 are regular octagons, so as to increase the anchoring strength of the anchoring steel bar 1.

The working principle is as follows: step one, when the pile foundation steel bar is anchored, after the plugging block 302 rotates to open the plugging of the tightening groove 305, the mechanical anchoring piece 2 is pushed into the tightening groove 305 and the tightening large groove 306 of the anchoring device 3, so that the anchoring screw 201 is matched with the tightening groove 305, the tightening large groove 306 is matched with the tightening large block 203, at the moment, the plugging block 302 rotates to plug the tightening groove 305, and the mechanical anchoring piece 2 is clamped into the anchoring device 3 and cannot fall off;

step two, aligning the anchoring screw 201 of the mechanical anchoring part 2 to the anchoring thread 101 of the anchoring steel bar 1, at the moment, drawing out the pushing block 304, at the moment, holding the pushing block 304 by an operator to rotate, so that the mechanical anchoring part 2 is screwed on the anchoring steel bar 1 under the matching of the screwing groove 305, the screwing large groove 306 and the plugging block 302, and after screwing, rotating the plugging block 302 to open the plugging of the screwing groove 305, taking down the anchoring device 3 to continue operating other anchoring steel bars 1;

and step three, after the construction of the pile foundation is finished, the tightening large block 203 arranged at the bottom end of the mechanical anchoring part 2 is of a regular polygon structure, so that the friction force of the anchoring steel bar 1 on the pile foundation is larger, and the anchoring strength is increased.

Example 2

As shown in fig. 6 to fig. 7, an improvement is made on the basis of the embodiment 1: the anchoring screw 201 comprises a fixed seat 204 connected with a screwing large block 203 and a limiting seat 205 installed at the top of the fixed seat 204, a connection seat 206 is installed between the fixed seat and the limiting seat 205, the outer side of the connection seat 206 is integrally connected with a plurality of flexible connection bodies 207, a thread seat 202 is integrally connected between the flexible connection bodies 207, and a check ring located at the top of the anchoring thread 101 is arranged at the bottom of the anchoring steel bar 1.

By adopting the structure, after the anchoring thread 101 of the anchoring steel bar 1 is matched with the thread seat 202, the thread seat 202 can be lifted and the flexible connecting body 207 is pressed to deform by continuously rotating, because the thread seat 202 moves upwards, the length of the mechanical anchoring part 2 can be more compact, the operation of the anchoring device 3 is more convenient, if the traditional long thread matching is adopted, the length of the mechanical anchoring part 2 is inevitably overlong, the operation of the anchoring device 3 is not facilitated, and meanwhile, the thread path deviation is easy to occur, so that the matching degree is not high.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Furthermore, it should be understood that although the present specification describes embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and it is to be understood that all embodiments may be combined as appropriate by one of ordinary skill in the art to form other embodiments as will be apparent to those of skill in the art from the description herein.
