[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a high-strength anti-corrosion cloth bag for a wrapped concrete cast-in-place pile, including a cloth bag main body 1, a support mechanism 2 is fixed on the outer side of the cloth bag main body 1, the support mechanism 2 includes a support ring 201, a pressing block 202 is fixed on the inner wall of the support ring 201, the pressing block 202 penetrates the side wall of the cloth bag main body 1, a first oil groove 203 is opened on the inner end surface of the pressing block 202, and a slot-inserting rotating mechanism 207 is fixed in the support ring 201 and the pressing block 202, and the slot-inserting rotating mechanism 207 is communicated with the first oil groove 203 through a first connecting pipe 206.

[0027] In this embodiment, as Figure 1 and Figure 2As shown, the cloth bag body 1 is composed of two layers of woven polypropylene geotextiles and one layer of high-density polyethylene film, which are made into composite geotextiles through hot pressing and welding, and then the composite geotextiles are used to make a high-strength anti-corrosion cloth bag by bonding or hot pressing and welding, with good anti-corrosion effect.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, a first spring 204 is fixed in the first oil tank 203, and the inner end of the first spring 204 is fixed with a first piston 205. The first piston 205 is slidably connected in the first oil tank 203. The first spring 204 plays a role in propping up the first piston 205. During the process of pouring concrete into the cloth bag body 1, the first piston 205 will move under the extrusion of the concrete.

[0029] In this embodiment, as Figure 2 , Figure 4 and Figure 7 shown, the slot insertion and rotation mechanism 207 includes an oil cylinder 2071, and the oil cylinder 2071 is fixed in the support ring 201 and the pressing block 202. The oil cylinder 2071 is communicated with the first oil tank 203 through a first connecting pipe 206. A second piston 2072 is slidably connected in the oil cylinder 2071. The first connecting pipe 206 plays a role in connecting the oil cylinder 2071 and the first oil tank 203. Hydraulic oil is stored in the first oil tank 203. When the first piston 205 is extruded and moves, the second piston 2072 will move under the action of oil pressure.

[0030] In this embodiment, as Figure 2 , Figure 4 and Figure 7 shown, a second oil tank 2073 is opened at the outer end of the second piston 2072, and two third pistons 2074 are slidably connected in the second oil tank 2073. The inner end surface of the third piston 2074 is fixed with an extrusion block 2075, and the extrusion block 2075 penetrates through one side of the second piston 2072. When the second piston 2072 moves to the end, the extrusion block 2075 abuts against the inner wall of the oil cylinder 2071, and the extrusion block 2075 moves under the extrusion of the inner wall of the oil cylinder 2071, thereby driving the third piston 2074 to move.

[0031] In this embodiment, as Figure 2 , Figure 4 and Figure 7As shown, a third oil groove 2077 is formed in the inner end of the second piston 2072, and the third oil groove 2077 communicates with the second oil groove 2073 through a second connecting pipe 2076. A fourth piston 2078 is slidably connected in the third oil groove 2077, and a latch 2079 is fixed to the inner end face of the fourth piston 2078. The second connecting pipe 2076 serves to connect the third oil groove 2077 and the second oil groove 2073. Hydraulic oil is stored in the second oil groove 2073. When the third piston 2074 moves, the fourth piston 2078 moves under the action of oil pressure, thereby driving the latch 2079 to move.

[0032] In this embodiment, as Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, a rotating block 20710 is rotatably connected to the inner end of the second piston 2072, and a clamping groove 20711 is formed in the outer end face of the rotating block 20710. The latch 2079 is snap - connected in the clamping groove 20711. Initially, the latch 2079 is stuck in the clamping groove 20711, and the rotating block 20710 is in a locked state. After the latch 2079 moves with the fourth piston 2078 and leaves the clamping groove 20711, the rotating block 20710 can be unlocked.

[0033] In this embodiment, as Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, a convex block 20713 is fixed to the inner end of the second piston 2072, and the rotating block 20710 is connected to the convex block 20713 through a second spring 20712. The second spring 20712 is initially in a compressed state. After the rotating block 20710 is unlocked, the rotating block 20710 will automatically rotate under the action of the second spring 20712.

[0034] In this embodiment, as Figure 2 , Figure 4 , Figure 6 and Figure 7 shown, a rotating rod 20714 is fixed to the inner end face of the rotating block 20710, and a groove 208 is formed in the inner end face of the pressing block 202. The rotating rod 20714 is slidably connected in the groove 208. The movement of the second piston 2072 drives the movement of the rotating rod 20714. The rotating rod 20714 is inserted vertically into the gap between two steel bars. After the second piston 2072 moves to the end, the rotating block 20710 is unlocked and automatically rotates, thereby driving the rotating rod 20714 to rotate to a horizontal state. The rotating rod 20714 is perpendicular to the steel bars, and the rotating rod 20714 is stuck in the steel bars, which is convenient for supporting the main body 1 of the cloth bag.

[0035] Usage method and advantages of the present invention: The high-strength anti-corrosion cloth bag for concrete-filled wrapped piles works as follows:

[0036] As Figures 1 to 7 shown: The designed diameter of the cloth bag body 1 is more than 1% larger than the designed pile diameter, and the length is 2 - 3 m longer than the pile length. The cloth bag body 1 is composed of two layers of woven polypropylene geotextiles and one layer of high-density polyethylene film, and is made into a composite geotextile by hot pressing and welding. Then, the composite geotextile is used to make a high-strength anti-corrosion cloth bag formed by bonding or hot pressing and welding, which is a composite geotextile bag. The overlapping length of the two layers at the bonding seam is more than 20 cm. The sealing performance of the butt joint is strictly monitored and impermeability detection is carried out. The connection strength of the butt joint in the tensile direction is not lower than the tensile strength of the materials used. The water-proof performance of the composite geotextile bag meets the vertical permeability coefficient k ≤ 2.3x10-11 cm / s, and the impermeability index is met at the joint. First, make a hole underground, then drive the steel bars into the hole. Next, put the cloth bag body 1 on the outside of all the steel bars, and the support ring 201 abuts against the hole wall. Subsequently, pour concrete into the cloth bag body 1. The anti-corrosion wrapped cloth bag is firmly combined with the concrete pile wall, leaving a connection length with the waterproof layer at the bottom of the bearing platform or other foundations. The pressing block 202 is extruded by the concrete, and together with the support ring 201, it can clamp the cloth bag body 1. The first piston 205 moves due to the extrusion of the concrete. The second piston 2072 and the rotating rod 20714 move as a whole. The rotating rod 20714 leaves the groove 208 and inserts between two adjacent steel bars. When the second piston 2072 moves to the end, the extrusion block 2075 moves due to the extrusion of the inner wall of the oil cylinder 2071, thereby driving the third piston 2074 to move. The fourth piston 2078 moves to drive the bolt 2079 to move. The bolt 2079 leaves the rotating block 20710, and the rotating block 20710 automatically rotates under the action of the second spring 20712, thereby driving the rotating rod 20714 to rotate. The rotating rod 20714 rotates to the horizontal state and is stuck in the steel bar seam, facilitating the top support of the cloth bag body 1.

[0037] In summary, the high-strength anti-corrosion cloth bag for concrete-filled wrapped piles achieves the purposes of high-strength anti-corrosion and support for anti-deformation, meeting people's usage requirements.
