[0020] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a static pressure anchor pile includes a first section pile 1, a middle section pile 2 and a tail pile. The first section pile 1, the middle section pile 2 and the tail pile are pressed into the soil layer 5 from bottom to top in sequence. The tail pile is a barbed pile 3, and barbs 32 of the barbed pile 3 are arranged on the side wall of the tail pile. The material of the barbs 32 is bendable material. After the barbed pile 3 is pressed into the ground, the barbs 32 are inserted into the soil layer 5 near the side wall of the barbed pile 3, increasing the friction between the side wall and the soil layer 5, and thus increasing the overall bearing capacity of the static pressure anchor pile. In addition, the first section pile 1 includes a pile tip 11 arranged at the bottom, a first pile body 12 and a pile cap 6 arranged at the upper part of the pile body. The middle section pile 2 includes a second pile body 21 and a pile cap 6.

[0021] Preferably, the bendable material is steel bar or plastic. The material of the barbs 32 can be selected according to the requirements of the bearing capacity. Generally, steel bars with good toughness and high strength, plastics, etc. can be selected.

[0022] Preferably, the mold of the barbed pile 3 includes a vertically arranged template 33 and a plurality of reserved holes arranged on the template 33. The plurality of reserved holes are used to fix the barbs 32 when prefabricating the barbed pile 3.

[0023] Preferably, the barbed pile 3 includes a cured concrete pile foundation 31, a steel reinforcement cage and barbs 32. The steel reinforcement cage is embedded in the pile foundation 31. The barbs 32 are partially embedded in the pile foundation 31, one end extends into the steel reinforcement cage, and the other end extends outside the pile foundation 31. The barbs 32 extend to a deeper position inside the pile foundation 31, which is more firm and prevents falling off during use.

[0024] Preferably, the barbed pile 3 further includes one or two pile caps 6. The barbed pile 3 can be set as one or more. The pile cap 6 is used to connect the barbed pile 3 with the middle section pile 2 or other barbed piles 3. The specific quantity and position can be determined according to the pile body connected with the barbed pile 3.

[0025] Preferably, the diameter of the barbs 32 is less than or equal to 14 mm. In order not to affect the normal piling process, the diameter of the barbs 32 should not be too large, and it is more appropriate to control it within the range of 14 mm.

[0026] Preferably, the barbs 32 are bent to a position parallel to the side wall of the barbed pile 3 during transportation, and are bent to form a preset included angle with the side wall of the barbed pile 3 during use. In addition, the included angle is preferably an acute angle.

Set up the piling equipment 4 at the construction site and ensure that the piling equipment 4 can operate normally.

[0034] Construction process of piling:

[0035] Step 1: Determine the pile position.

[0036] Step 2: Move the piling equipment 4 to the pile position to be driven.

[0037] Step 3: After using the piling equipment 4 to drive the first section of pile 1 into the soil layer 5, connect the middle section of pile 2 to the tail of the first section of pile 1, and use the piling equipment 4 to drive the middle section of pile 2 of the pile into the soil layer 5. In this way, sequentially construct the middle sections of pile 2 of the remaining piles.

[0038] Step 4: After the construction of the middle section of pile 2 of the pile is completed, connect the segmented barbed pile 3 to the tail of the middle section of pile 2, and use the piling equipment 4 to drive the segmented barbed pile 3 into the soil layer 5. In this way, sequentially construct the segmented barbed pile 3 of the remaining piles until the piling is completed.
