Under some special geological conditions, such as soft soil, sandy soil, expansive soil, etc., traditional foundation reinforcement methods are often difficult to meet the requirements, resulting in the risk of settlement, tilting or even collapse of the foundation of power facilities. In addition, extreme climatic conditions and natural disasters also put forward higher requirements on the stability of the foundation of power facilities. Therefore, it is particularly important to develop an efficient, economical and reliable foundation reinforcement method.

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] See also Figure 1-3 A pressure-type anchor rod 12 power foundation mechanism provided by an embodiment of the present invention includes a pile body 1, two anchor rods 12, a steel plate 2 and a first I-beam 3. The pile body 1 is vertically buried in the ground 11, and the upper end of the pile body 1 extends out of the ground; the two anchor rods 12 are vertically fixedly connected in the pile body 1, and the upper ends of the two anchor rods 12 are higher than the upper end of the pile body 1; the steel plate 2 is fixedly connected to the pile body 1, and a steel column 21 is fixedly connected to the steel plate 2, and a column sleeve 211 is coaxially slidably connected to the steel column 21, and a height adjustment component is arranged between the column sleeve 211 and the steel column 21; the first I-beam 3 is fixedly connected to the column sleeve 211, and a connecting piece 31 connected to the power facility is arranged on the first I-beam 3, and the connecting piece 31 includes a plurality of screw holes, and a threaded rod screwed to the power facility is screwed on each screw hole.

[0019] First, a curing agent such as cement slurry or cement mortar is injected into the soil and fully mixed with the soil to form a cement slurry mixture. The second I-beam is then inserted into the cement slurry mixture, and then two anchor rods 12 are inserted into the cement slurry mixture next to the second I-beam (the anchor rod 12 rod body is anti-corrosive treated by hot-dip galvanizing process). The two anchor rods 12 are symmetrical with respect to the second I-beam. After the cement slurry mixture solidifies, the cement slurry mixture forms a pile body 1, the second I-beam is taken out of the pile body 1, and cement slurry is injected into the gap in the pile body 1 where the second I-beam is taken out. After the cement slurry solidifies, the steel plate 2 is fixedly connected to the pile body 1 (by drilling holes on the pile body 1 and screwing). After the construction is completed, quality inspection and acceptance work must be carried out to ensure that the construction quality meets the design requirements. The inspection content includes key indicators such as the strength of the pile body 1, the pull-out resistance of the anchor rod 12, and the density of the grouting body. The subsequent installation and commissioning of the power facilities can be carried out only after the acceptance is qualified.

[0020] Compared with the prior art, the present invention provides a pressure-type anchor rod 12 power foundation structure and a forming method thereof. This power foundation structure avoids construction methods such as expanding the foundation, adding counterweights, and reinforcing pile foundations. Instead, a stable anchoring system is formed through the interaction between the anchor rod 12 and the surrounding soil, which has the advantages of strong pull-out resistance, convenient construction, and low cost.

[0021] Among them, the end of the anchor rod 12 is fixedly connected with a carrier 121, which can concentrate the tension exerted on the anchor rod 12 in a smaller area, making the stress more concentrated. This can increase the friction and mechanical bite force between the anchor rod 12 and the surrounding structure, thereby improving the transmission efficiency of the anchoring force.

[0022] There are a plurality of limit piles 32 slidably connected to the first I-beam 3 , and each limit pile 32 is inserted into the ground 11 to limit the position of the first I-beam 3 and adjust the arc inclination of the first I-beam 3 .

[0023] In another embodiment provided by the present invention, referring to Figure 2 , also includes two height adjustment components 4, the height adjustment component 4 includes a connecting plate 41, a driving member and a supporting plate 42 fixedly installed on the ground, the supporting plate 42 is rotatably connected with a double-threaded screw 421, the supporting plate 42 is horizontally slidably connected with a first slider 422 and a second slider 423, the first slider 422 and the second slider 423 are both threadedly connected to the double-threaded screw 421, the connecting plate 41 is clamped in the recess of the first I-beam 3, the first slider 422 and the second slider 423 are both hinged with an articulated rod 5, the other ends of the two articulated rods 5 are hinged to the connecting plate 41, the driving member is used to drive the double-threaded screw 421 to rotate, specifically, the driving member includes a driving motor, and the output shaft of the driving motor is coaxially and fixedly connected with the double-threaded screw 421.

[0024] When the geology changes and the land 11 here sinks, the height of the power facilities here is lower than that of other places (for example, when one of the four corners of the power tower is lower, it may tilt). At this time, it is necessary to fix the rotating shaft of the drive motor coaxially with the double-threaded screw 421, and the two drive motors simultaneously drive the two double-threaded screws 421 to rotate, driving the first slider 422 and the second slider 423 to approach each other, and the hinged rods 5 on the first slider 422 and the second slider 423 simultaneously abut the first I-beam 3, so that the first I-beam 3 can slide relative to the steel column 21 through the column sleeve 211, and the first I-beam 3 moves vertically upward, so that the power facilities move upward, thereby preventing the power equipment from tilting.

[0025] The present invention also provides a forming method, which is implemented based on a pressure-type anchor rod 12 power foundation mechanism, and includes the following steps: S1, opening a groove on the land 11, selecting a certain position in the groove, driving the stirring shaft to rotate through a power device, and driving the stirring blades to cut and stir the in-situ soil, and then, during the stirring process, injecting a curing agent such as cement slurry or cement mortar into the soil, and fully mixing with the soil to form a cement slurry mixture; S2, vertically inserting a second I-beam with an anti-adhesive coating on the surface into the cement slurry mixture, inserting an anchor rod 12 with a special adhesive coating on the surface into the cement slurry mixture, and after the cement slurry mixture solidifies, the cement slurry mixture forms a pile body 1, and then taking out the second I-beam; S3, filling the gap in the pile body 1 after the I-beam is taken out with cement slurry until the cement slurry solidifies; S4, fixing the steel plate 2 to the pile body 1 by bolts, and installing power facilities on the first I-beam 3 on the steel plate 2.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
