Description

Steel pipe anchor rod static pressure pile
Technical Field
The utility model relates to a building engineering technical field especially relates to a steel pipe stock static pressure pile.
Background
Due to the influences of construction of projects around the building, increase of use load, consolidation and settlement of soft soil foundations and the like, the normal use functions of the building are influenced by settlement, inclination and the like of the building, and foundation reinforcement is needed. For the foundation reinforcement of existing buildings, the use of anchor static piles is one of the common treatments.
The pile type of the anchor rod static pressure pile generally adopts a prefabricated reinforced concrete small-section square pile (the side length is 200mm-350 mm) or a small-diameter steel pipe pile (the diameter is 100mm-500 mm), and the bearing capacity of a single pile is low, so that a large number of anchor rod static pressure piles are often required to be designed when foundation fixing is carried out.
For foundation reinforcement of existing buildings, pile pressing holes need to be drilled in a foundation bottom plate, and after anchor static pressure piles are constructed, the pile pressing holes are sealed. And the original foundation slab is damaged by digging too many pile pressing holes, so that the recovery is difficult. Therefore, how to improve the single pile bearing capacity of the anchor rod static pressure pile so as to reduce the pile arrangement quantity during foundation fixing and setting is a technical problem to be solved urgently in the field.
Disclosure of Invention
The utility model aims at providing a steel pipe stock static pressure stake according to above-mentioned prior art not enough, through at steel pipe stock static pressure stake outside welding hoop structure, can effectively improve the bearing capacity, reduce the required pile foundation quantity of ground reinforcement.
The utility model discloses the purpose is realized accomplishing by following technical scheme:
the utility model provides a steel pipe stock static pressure stake, includes the steel pipe, its characterized in that: the steel pipe anchor rod static pressure pile further comprises a hoop arranged on the periphery of the surface of the pipe body of the steel pipe, and the hoop is arranged around the steel pipe in the circumferential direction and is fixedly connected to the steel pipe.
And the steel pipe and the hoop are welded and fixed.
The hoops are arranged at regular intervals along the length direction of the steel pipe.
The hoop is made of steel bars or round steel.
The steel bars are HRB400 steel bars; the round steel is Q235 round steel.
The steel pipe anchor rod static pressure pile is formed by combining a plurality of sections of steel pipes.
The steel pipe is a seamless steel pipe or a rolled steel pipe with the diameter not more than 500 mm.
The utility model has the advantages that: the hoop structure is reliable in installation and ingenious in design, and the improvement of the side frictional resistance between pile soils is reliably realized, so that the pulling resistance and the compression resistance bearing capacity of the steel pipe anchor rod static pressure pile are improved; the construction is convenient, the cost is lower, and the method has wide popularization and application prospect.
Drawings

figure 2 is a plan view of the middle hoop structure of the present invention;
figure 3 is a cross-sectional view of the middle hoop structure of the present invention.
Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-3, the labels 1-2 are respectively expressed as: steel pipe 1, hoop 2.
Example (b): as shown in fig. 1 to 3, the steel pipe anchor static pile in the present embodiment includes a steel pipe 1 and a hoop 2, wherein the hoop 2 is a ring-shaped structure welded and fixed on the periphery of the steel pipe 1, and the ring-shaped structure increases the bearing capacity of the steel pipe anchor static pile by enlarging the local sectional area of the steel pipe anchor static pile, and reduces the number of pile foundations required for foundation reinforcement.
The steel pipe anchor rod static pressure pile in the embodiment is formed by combining a plurality of sections of steel pipes 1, and the length of a single section of steel pipe is designed according to design requirements. The hoops 2 are uniformly arranged at intervals along the length direction of the single-section steel pipe 1, and the local spacing distance, the number of the hoops 2 and other engineering parameters can be adjusted according to the design requirements.
In some embodiments, hoop 2 may be formed from steel or round bar, which is a simple material, typically available at the construction site. When the hoop 2 adopts steel bars, the steel bars are HRB400 steel bars; and when the hoop 2 adopts round steel, the round steel is Q235 round steel, thereby ensuring the effect. The steel pipe 1 is a seamless steel pipe or a rolled steel pipe having a diameter of not more than 500 mm.
In the embodiment, in specific implementation: firstly, welding a hoop 2 used for a hoop structure at the periphery of a steel pipe 1 used for each section of steel pipe anchor rod static pressure pile by using a welding tool; then pressing the single-section steel pipes 1 into foundation soil by adopting an anchor rod static pressure pile construction device, and connecting the single-section steel pipes in a welding mode; and after the pressing-in length of the steel pipe anchor rod static pressure pile reaches the design requirement, closing the pile pressing hole.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims.
