Description

Technical Field

[0001] The present invention belongs to the technical field of offshore foundation treatment, and in particular relates to a semi-automatic soil-fixing wheel-pierced steel pipe pile for offshore foundation and a working method thereof. Especially for pile foundation design for treating soft soil foundation, the present invention can effectively reduce the length of the pile foundation and reduce the difficulty of offshore pile foundation construction and piling. Background Art

[0002] At present, the traditional pile types commonly used to deal with soft soil foundations include cast-in-place piles, steel pipe piles and prestressed pipe piles. Among them, cast-in-place piles are difficult to construct, have a long construction period, complex processes, single functions, and cannot reinforce the surrounding soil. They cannot provide effective bearing capacity when encountering soil with small lateral friction resistance. In view of offshore construction conditions, concrete pouring is difficult and expensive. Traditional steel pipe piles are a common pile foundation type in offshore engineering and are suitable for the construction of offshore structures, but they cannot reinforce the surrounding soil and cannot provide effective bearing capacity for soil with small lateral friction resistance. Prestressed pipe piles have the same problems as cast-in-place piles.

[0003] By arranging wheel spikes on the side walls of the steel pipe pile, the wheel spikes can be inserted into the soil to increase the lateral friction resistance and improve the effective bearing capacity; however, the wheel spikes need to be driven into the soil only after the entire steel pipe pile is driven in, and a power device for driving the wheel spikes to extend needs to be arranged in the steel pipe pile, which increases the overall cost of the steel pipe pile. In addition, the arrangement of the wheel spikes and the power device occupies a certain space in the steel pipe pile, which affects the implementation of pouring grouting material around the steel pipe pile and affects the overall construction difficulty. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a semi-automatic fixed soil wheel-thorn steel pipe pile for offshore foundation and a working method thereof.

When the entire steel pipe pile is driven in, the internal volume of the telescopic bag can be increased by pouring grouting material into the telescopic bag, and the plurality of arc-shaped plates and the thorn body can be driven to extend outward into the soil. There is no need to independently arrange a power device in the steel pipe pile, and the work of pouring grouting material around the steel pipe pile can be completed at the same time, without affecting the overall construction difficulty.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0032] The present invention provides a semi-automatic soil-fixing wheel-thorn steel pipe pile for offshore foundations. The steel pipe pile is used as a basis and can be applied to the foundation treatment of offshore structures. A wheel-thorn mechanism 3 is introduced; the extension of the thorn body 303 can increase the lateral resistance of the pile body, thereby increasing the vertical bearing capacity of the pile; the introduction of a telescopic bag 305 that can achieve semi-automatic extension control can reduce the construction difficulty while achieving the effect of enhancing the bearing capacity; grouting holes are arranged on the wheel-thorn mechanism 3, which can realize the injection of grouting material around the pile, thereby achieving the purpose of reinforcing the soil around the pile.

[0033] The semi-automatic soil-fixing wheel-thorn steel pipe pile proposed in the present invention can be used not only for offshore foundations, but also for other scenarios involving foundations, which will not be described in detail here.

[0034] Optional, such as Figures 1 to 8 As shown, the semi-automatic fixed soil wheel-pierced steel pipe pile includes a steel pipe pile body 1, a shell 2, a wheel-pierced mechanism 3 and a grouting pipe 4.

[0035] Optional, such as Figure 1 As shown, the steel pipe pile body 1 includes a plurality of accommodating cavities 101, and a plurality of first through holes 102 opened on the side walls of the accommodating cavities 101; the first through holes 102 are used for the extension and retraction of the thorn body 303 in the wheel thorn mechanism 3; a shell 2 is arranged in each accommodating cavity 101, and the first through holes 102 on adjacent accommodating cavities 101 are staggered, which can improve the connection strength between the steel pipe pile body 1 and the soil.

[0036] Correspondingly, such as Figure 2 and Figure 3 As shown, the side wall of the housing 2 is provided with second through holes 203, the number and position of the second through holes 203 correspond to the first through holes 102; the second through holes 203 are used for the extension and contraction of the thorn body 303 in the wheel thorn mechanism 3. The two ends of the housing 2 are respectively provided with an upper cover 201 and a lower cover 202, and the middle position of the upper cover 201 and the lower cover 202 is respectively provided with a third through hole 205 for setting the grouting pipe 4.

[0037] like Figure 3As shown, a track 204 is provided on both the upper cover 201 and the lower cover 202; the width of the track 204 is equal to the arc plate 301 in the wheel thorn mechanism 3; the setting of the track 204 improves the stability of the movement of the arc plate 301 and provides a guarantee for the driving mode of the semi-automatic driving of the thorn body 303.

[0038] like Figures 4 to 6 As shown, the wheel thorn mechanism 3 includes a plurality of arc plates 301 that can form a cylindrical structure, and each arc plate 301 is provided with a thorn body 303; a telescopic bag 305 is provided in the cylindrical structure formed by the plurality of arc plates 301, and a grouting hole is provided on the telescopic bag 305.

[0039] Specifically, a telescopic bag 305 is arranged in the cylindrical structure composed of multiple arc plates 301, and a grouting hole is arranged on the telescopic bag 305. When the entire steel pipe pile is driven in, the volume of the telescopic bag 305 can be increased by pouring grouting material into the telescopic bag 305, and the multiple arc plates 301 and the thorn body 303 can be driven outward into the soil. There is no need to independently set up a power device in the steel pipe pile, and the work of pouring grouting material around the steel pipe pile can be completed at the same time, without affecting the overall construction difficulty.

[0040] A fourth through hole 302 is provided between the arc plate 301 and the thorn body 303. The thorn body 303 is a hollow structure, and a plurality of fifth through holes 304 are provided on the side wall of the thorn body 303. Grouting material can enter the thorn body 303 along the fourth through hole 302 and flow out through the fifth through hole 304, thereby realizing the work of pouring grouting material around the steel pipe pile.

[0041] like Figure 6As shown, the end of the telescopic bag 305 is provided with a grouting hole, and the grouting hole is connected to the grouting pipe 4. Optionally, the two ends of the telescopic bag 305 are respectively provided with a first grouting hole 3051 and a second grouting hole 3052; the grouting pipe 4 is connected to the telescopic bag 305 through the first grouting hole 3051 and the second grouting hole 3052, and the grouting material can enter all the telescopic bags 305 through the grouting pipe 4; and enter the fourth through hole 302 through the pressure valve 3053 provided on the side wall of the telescopic bag 305, and the number and position of the pressure valve 3053 correspond to the thorn body 303. The telescopic bag 305 can be optionally a rubber bag, which is elastic. The setting of the pressure valve 3053 can avoid the problem of grouting material entering the thorn body 303 at the initial stage of grouting. If the grouting enters the thorn body 303 at the initial stage of grouting, the volume in the telescopic bag 305 cannot be guaranteed, and the depth of the thorn body 303 entering the soil cannot be guaranteed, which affects the fixing strength and the grouting effect. After the pressure valve 3053 is set, the grouting material is allowed to enter the thorn body 303 only after the moving pressure is reached, which can avoid the grouting material entering the thorn body 303 at the initial stage of grouting, and ensure the depth of the thorn body 303 entering the soil and the grouting effect.

[0042] like Figure 1 to Figure 7 As shown, a working method of the semi-automatic fixed soil wheel-pierced steel pipe pile for offshore foundation provided by the present invention is: the steel pipe pile is driven into a preset position; after the entire steel pipe pile is driven, grouting material is poured into the telescopic bag 305, and the volume of the telescopic bag 305 is increased by the injection of grouting material, and the multiple arc plates 301 and the thorns 303 are driven to extend out of the side wall of the steel pipe pile and enter the soil.

[0043] The present invention introduces a wheel thorn mechanism 3, and the thorn body 303 penetrates deep into the soil around the pile body, and through a multi-layer staggered arrangement, the lateral resistance of the pile body is increased, thereby increasing the vertical bearing capacity of the pile. The wheel thorn mechanism 3 can be set at any section of the pile body entering the soil, and the position of the wheel thorn group can be adjusted according to the characteristics of the soil body to increase the vertical bearing capacity of the pile body while increasing the horizontal bearing capacity of the pile body. The wheel thorn mechanism 3 introduces a grouting hole to realize the injection of grouting material around the pile body, thereby achieving the purpose of reinforcing the soil around the pile and further enhancing the bearing capacity of the pile body.

[0044] The present invention is based on steel pipe piles and can be applied to the foundation treatment of offshore structures. The semi-automatic wheel thorn mechanism 3 introduced injects high-pressure grouting material or high-compressed air to make the wheel thorns penetrate into the surrounding soil. The operation is simple and can be implemented on the ground or on an offshore construction platform. While achieving the effect of enhancing the bearing capacity of the pile body, the implementation difficulty is reduced and the construction period is shortened. The steel pipe piles in the present invention are not only suitable for the design and construction of the foundation treatment of offshore structures, but can also be used in the design and construction of pile foundations on land or under other working conditions.

[0045] The semi-automatic fixed soil wheel-thorn steel pipe pile of the present invention is described below by way of embodiments:

[0047] The present embodiment provides a semi-automatic fixed soil wheel-thorn steel pipe pile for offshore foundation, including a steel pipe pile body 1, a shell 2, a wheel-thorn mechanism 3 and a grouting pipe 4. Four arc-shaped plates 301 and four thorn bodies 303 form a wheel-thorn group, and a tubular structure is formed in the middle. Taking the four wheel-thorn groups as an example, the number of thorn bodies 303 can be increased or decreased according to the usage. The wheel-thorn group includes an arc-shaped plate 301, and a hole is opened on the arc-shaped plate 301. One end is connected to the telescopic bag 305, and the other end is connected to the thorn body 303. The thorn body 303 is a tubular structure with a spike shape on the head, and the length can be determined according to actual needs. The main structural material of the telescopic bag 305 is a telescopic rubber bag. The first grouting hole 3051 and the second grouting hole 3052 are set at the upper and lower ends of the telescopic bag 305 to connect the grouting pipe 4. The upper cover 201 and the lower cover 202 are steel plates with tracks 204. The arc plate 301 can slide in the track 204. To facilitate sliding, a layer of fine sand or other materials that can enhance sliding ability can be sprinkled at the bottom of the track 204. The upper cover 201 and the lower cover 202 have basically the same structure and are arranged in a mirror image. The upper cover 201 and the lower cover 202 are welded to the inner wall of the steel pipe pile body 1 without any gaps.

[0048] Installation method: weld the lower cover 202 to the steel pipe pile body 1 with the track facing upward; put a set of wheel spike groups into the track 204 of the lower cover 202; put the telescopic bag 305 into the tubular structure formed in the center of the wheel spike group, and connect the pressure valve 3053 in the telescopic bag 305 with the fourth through hole 302 on the arc plate 301; turn the track 204 of the upper cover 201 downward, and insert the wheel spike group into the track 204 of the upper cover 201; repeat the above content, arrange other layers of wheel spike groups, and arrange the wheel spike groups alternately, and ensure that the upper cover 201 and the lower cover 202 are connected through the grouting connection holes; connect the grouting pipe 4 at the topmost grouting connection hole, and the grouting pipe 4 is reserved to the top of the steel pipe pile, and connected to the high-pressure grouting equipment.

[0049] Usage and working principle: The steel pipe pile is driven into the soil; after the pile is in place, grouting is performed through the grouting pipe 4, which is fixed by the upper cover 201 and the lower cover 202, and the telescopic bag 305 begins to expand in all directions, thereby pushing the arc plate 301 to move radially outward, and inserting the thorn body 303 into the soil through the first through hole 102 reserved on the surface of the steel pipe pile; when the thorn body 303 is completely inserted into the soil, the purpose of increasing the side friction of the pile body and increasing the bearing capacity of the pile is achieved.

[0050] In this embodiment, the injection of high-pressure grouting material may be replaced with high-compressed air to achieve the purpose of completely inserting the thorn body 303 into the soil, which will not be elaborated here.

[0051] Embodiment 2:

[0052] The present embodiment is different from the first embodiment in that the soil can be reinforced; the present embodiment provides a semi-automatic fixed soil wheel-thorn steel pipe pile for offshore foundation, including a steel pipe pile body 1, a shell 2, a wheel-thorn mechanism 3 and a grouting pipe 4. Four arc-shaped plates 301 and four thorn bodies 303 form a wheel-thorn group, and a tubular structure is formed in the middle. Taking the four wheel-thorn groups as an example, the number of thorn bodies 303 can be increased or decreased according to the usage. The wheel-thorn group includes an arc-shaped plate 301, and a hole is opened on the arc-shaped plate 301. One end is connected to the telescopic bag 305, and the other end is connected to the thorn body 303. The thorn body 303 is a tubular structure with a spiked head, and the length can be determined according to actual needs. The main structure material of the telescopic bag 305 is a telescopic rubber bag. The first grouting hole 3051 and the second grouting hole 3052 are set at the upper and lower ends of the telescopic bag 305 to connect the grouting pipe 4. The upper cover 201 and the lower cover 202 are steel plates with tracks 204. The arc plate 301 can slide in the track 204. To facilitate sliding, a layer of fine sand or other materials that can enhance sliding ability can be sprinkled at the bottom of the track 204. The upper cover 201 and the lower cover 202 have basically the same structure and are arranged in a mirror image. The upper cover 201 and the lower cover 202 are welded to the inner wall of the steel pipe pile body 1 without any gaps.

[0053] In this embodiment, pressure valves 3053 are arranged around the telescopic bag 305. When a certain pressure is reached, the pressure valve 3053 will open. The pressure valve 3053 is connected to the opening of the thorn body 303. Grouting connection holes are arranged at the upper and lower ends of the telescopic bag 305 (when there is only one group, only the upper part is provided with a connection hole) for connecting the grouting pipe 4.

[0054] Installation method: weld the lower cover 202 to the steel pipe pile body 1 with the track facing upward; put a set of wheel spike groups into the track 204 of the lower cover 202; put the telescopic bag 305 into the tubular structure formed in the center of the wheel spike group, and connect the pressure valve 3053 in the telescopic bag 305 with the fourth through hole 302 on the arc plate 301; turn the track 204 of the upper cover 201 downward, and insert the wheel spike group into the track 204 of the upper cover 201; repeat the above content, arrange other layers of wheel spike groups, and arrange the wheel spike groups alternately, and ensure that the upper cover 201 and the lower cover 202 are connected through the grouting connection holes; connect the grouting pipe 4 at the topmost grouting connection hole, and the grouting pipe 4 is reserved to the top of the steel pipe pile, and connected to the high-pressure grouting equipment.

[0055] The steel pipe pile is driven into the soil; after the pile is in place, grouting is performed through the grouting pipe 4, which is fixed by the upper cover 201 and the lower cover 202, and the telescopic bag 305 begins to expand in all directions, thereby pushing the arc plate 301 to move radially outward, and inserting the thorn body 303 into the soil through the first through hole 102 reserved on the surface of the steel pipe pile; when the thorn body 303 completely enters the soil, the telescopic bag 305 cannot continue to expand, and the pressure in the telescopic bag 305 will gradually increase. When the grouting material in the telescopic bag 305 reaches a certain pressure value, the pressure valve 3053 opens, allowing the grouting material to enter the tubular structure of the thorn body 303, and then inject the grouting material into the surrounding soil through the fifth through hole 304 on the tube body of the thorn body 303.

[0056] As an advanced solution of Example 1, this embodiment can increase the bearing capacity of the pile while reinforcing the soil around the pile.

[0057] The above description is only a preferred embodiment of the present embodiment and is not intended to limit the present embodiment. For those skilled in the art, the present embodiment may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present embodiment shall be included in the protection scope of the present embodiment.
