Description

Prefabricated screw pile

Technical Field

The utility model relates to the technical field of screw piles, in particular to a prefabricated screw pile.

Background

In the field of constructional engineering, along with the progress of urbanization and the requirement of environmental protection, prefabrication, modularization and assembly molding are the development directions. The existing foundation pile construction method mainly comprises two major types of filling piles and precast piles, the two types of pile foundation types are limited by construction technology, and the problems that if the precast piles are in soft soil foundation, the circumferential resistance of the piles is not fully exerted, the pile body strength cannot be fully exerted under vertical compressive load, the horizontal load resistance is not enough, the static pressure resistance of sand layers is too large, the piles are difficult to form, the adjacent buildings are seriously affected by soil compaction in construction, the pile spacing is large, the bearing platform is enlarged, the cost is increased and the like exist. The cast-in-place pile is easy to neck, the pile bottom is provided with ballast, and the pile head for discharging and removing mud in construction can pollute the environment, etc.

For example, the concrete prestressed pipe pile adopts a large-tonnage pile pressing machine to implant the pipe pile into soil, the pipe pile is cylindrical, the resistance between the pipe pile and the side wall of the soil is small, and the bearing capacity value is reduced. Although it has solved pile body concrete intensity and age problem, nevertheless there is the bearing capacity value low, because crowded soil pore-forming is difficult to become the stake in the sand bed, and applicable stratum scope is little.

And the pile is formed by drilling by using a steel drilling tool with a threaded shape through a large-torque drilling machine and then pouring concrete, so that the problem of the shape of a pile body is solved.

Therefore, in the method for forming the pile by using the cast-in-place pile and the precast pile, the pile forming difficulty is high, the bearing capacity of the pile body is low, the side friction resistance of the pile is small, the pile body strength is low, the adaptability to stratum is poor, and the problems of necking, pile breaking, low construction efficiency and the like are easy to occur.

At present, in the use of prefabricated screw pile, our workman discovers that the top of prefabricated screw pile only has a connecting hole, and the size is in order to be fixed, can't change the connecting hole on pile body and pile head top, brings inconvenience easily to the use of prefabricated screw pile, and the top pile head of prefabricated screw pile also lacks necessary protective structure, makes the pile head impaired easily, simultaneously, the pile body is in the pile down in-process, and the pile point position can't dismantle the change, does not change the use unfavorable for the pile body after the pile point grinds dullness.

For example, the prior patent publication CN106917404a provides a prefabricated screw pile, the device adopts high-strength concrete, the prefabricated pile body adopts high-strength concrete, the hole can be formed under the rotating condition, the prefabricated screw pile is implanted into the soil layer, and the functions of compression resistance and tensile resistance are achieved. Through holes in the pipe wall form nozzles at different directions at the front end of the drill bit, and the soil body is cut through high-pressure jet flow, so that the pile forming speed is improved.

However, the device is only suitable for forming holes under the rotating condition, the prefabricated screw piles are implanted into soil layers, and the size of the connecting holes at the pile body and the pile head top cannot be changed.

The top of current prefabricated screw stake, the top of prefabricated screw stake only has a connecting hole, and the size is in order to be fixed, can't change the connecting hole on pile body and pile head top, bring inconvenience easily to the use of prefabricated screw stake, and the top pile head of prefabricated screw stake also lacks necessary protective structure, makes the pile head impaired easily, simultaneously, the pile body is in the pile down in-process, and the pile point position can't dismantle the change, does not change the use that is unfavorable for the pile body after the pile point grinds dullness.
