DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0029] This embodiment provides a piling device based on water jet pre-drilled sheet piles, which includes a mother pile pre-drilling device and a sheet pile. The mother pile pre-drilling device is used to form a sheet pile hole in the soil, and the sheet pile hole is used to limit the insertion of the sheet pile. Figures 1 to 2 As shown, the mother pile pre-drilling device includes a mother pile 1 and a drilling mechanism. The mother pile 1 can be a hollow steel pipe, with its hollow direction arranged along its length. The drilling mechanism is installed inside the mother pile 1. The drilling mechanism includes at least one water jet component and a driving assembly. Both the water jet component and the driving assembly are installed inside the mother pile 1. The water jet component has multiple nozzles, each facing the bottom of the mother pile 1, which cut the soil below the mother pile 1 with water jets. The driving assembly is connected to the water jet component and is used to drive the water jet component to reciprocate, thereby increasing the spray range of the nozzles. The driving assembly includes a driving component and at least one driven component 3. The two ends of the driven component 3 are connected to the water jet component and the driving component, respectively. The driving component drives the water jet component to reciprocate through the driven component 3. The reciprocating motion of the water jet component increases the spray range of the nozzles, thereby increasing the cutting range of the high-pressure water jet from the nozzles on the soil. Increasing the cutting range effectively disperses the soil, improving the cutting efficiency and effect of the drilling mechanism. This reduces the friction between the subsequently driven sheet piles and the soil, enabling rapid hole enlargement and pre-drilling operations via the mother pile 1 and the drilling mechanism. This effectively solves the problem in existing technologies where the limited number and fixed positions of the nozzles on the water jetting rod 22 result in a small high-pressure water jet spray range and low cutting efficiency.

[0030] In this embodiment, there can be multiple water spray elements, all of which are installed inside the mother pile 1. The nozzles of each water spray element face the bottom of the mother pile 1. The number of driven elements 3 can be the same as the number of water spray elements, with each driven element 3 connected to a water spray element. There can be one driving element, which is connected to multiple driven elements 3. The driving element acts as a power source to drive the multiple driven elements 3, and each driven element 3 can drive the water spray element connected to it to reciprocate. This arrangement allows multiple water spray elements to be controlled by a single driving element while simplifying the structure of the driving assembly.

[0031] It is understood that, in this embodiment, please refer to Figure 3, the number of the water spraying members can be two, and the number of the driven members 3 can also be two. The two water spraying members are respectively connected to the two driven members 3. The two water spraying members are symmetrically arranged on two sides of the driving member. The driving member drives the two water spraying members to swing synchronously through the two driven members 3. The swinging angle and the swinging direction of the two water spraying members are consistent. By setting the swinging direction and the swinging angle of the two water spraying members to be consistent, the problem that the cutting water columns sprayed from the nozzles of the two water spraying members collide with each other when the two water spraying members rotate synchronously to the direction close to the driving member can be avoided. In this embodiment, by setting the swinging direction and the swinging angle of the two water spraying members to be consistent, the above problem can be avoided, and the cutting effect of the cutting water columns sprayed from the two water spraying members on the soil can be improved.

[0032] Please refer to Figure 4 and Figure 5 , the water spraying member can include a water spraying rod 22, a rotating shaft 23, and a water inlet pipe 21. The rotating shaft 23 is installed in the female stake 1 through a bearing. The bearing is installed in a manner that facilitates the rotation of the rotating shaft 23. The water spraying rod 22 is fixedly installed on the rotating shaft 23 and can rotate with the rotating shaft 23. The water inlet pipe 21 is vertically installed in the female stake 1, and the water inlet pipe 21 and the water spraying rod 22 are connected through a hose. By connecting the water spraying rod 22 and the water inlet pipe 21 through the hose, the connection between the water inlet pipe 21 and the water spraying rod 22 will not be affected when the water spraying rod 22 rotates with the rotating rod 32. The nozzle penetrates the water spraying rod 22 and communicates with the water inlet pipe 21. The water inlet pipe 21 is used to output high-pressure water to the water spraying rod 22. In actual operation, high-pressure water from the outside can be delivered into the water spraying member through the water inlet pipe 21. The high-pressure water entering the water inlet pipe 21 can be sprayed to the soil below the female stake 1 through the nozzle of the water spraying rod 22. The high-pressure water column sprayed by the water spraying rod 22 can disperse the soil below the female stake 1, thereby realizing the cutting operation on the soil below the female stake 1. At the same time, during the cutting process, the driving member drives the driven member 3, and the driven member 3 drives the water spraying rod 22 to reciprocate through the rotating shaft 23, thereby increasing the spraying range of the nozzles on the water spraying rod 22 and maximizing the cutting operation on the soil below the female stake 1, thereby improving the cutting effect and the cutting efficiency.

[0033] Please refer to Figure 4 and Figure 5The driven part 3 comprises a second rotating shaft 31, a rotating rod 32 and a limiting rod 33. One end of the second rotating shaft 31 is rotatably installed in the female stake 1, and the other end of the second rotating shaft 31 is connected to the driving part. One end of the limiting rod 33 is fixedly connected to the first rotating shaft 23, and the limiting rod 33 is provided with a long hole 331. The limiting rod 33 and the water spraying rod 22 are both vertically installed in the female stake 1. The width of the limiting rod 33 is slightly smaller than the width of the water spraying rod 22, so that the swinging angle of the water spraying rod 22 can be maximized when the limiting rod 33 swings, thereby increasing the cutting range of the high-pressure water column sprayed from the water spraying rod 22. One end of the rotating rod 32 is fixedly installed on the second rotating shaft 31, and the other end of the rotating rod 32 is slidably installed in the long hole 331. By arranging the second rotating shaft 31, the rotating rod 32 and the limiting rod 33, the driven part 3 can convert the rotation of the second rotating shaft 31 into the swinging of the limiting rod 33. The driving part drives the rotating rod 32 to rotate through the second rotating shaft 31, and the rotating rod 32 drives the limiting rod 33 to swing back and forth with the first rotating shaft 23 as the center and the length of the limiting rod 33 as the radius, and drives the water spraying rod 22 to swing synchronously. In this embodiment, in order to ensure that the rotating rod 32 can swing back and forth with the first rotating shaft 23 as the center and the length of the limiting rod 33 as the radius, the length of the rotating rod 32 and the length of the long hole 331 need to be limited. Taking the length direction of the female stake 1 as the reference, the sum of the length of the rotating rod 32 and the vertical distance from the second rotating shaft 31 to the center line of the long hole 331 needs to be less than half the length of the long hole 331. Through this arrangement, when the rotating rod 32 rotates vertically upward, the uppermost end of the rotating rod 32 is located in the long hole 331. When the rotating rod 32 rotates vertically downward, the lowermost end of the rotating rod 32 is still located in the long hole 331.

[0034] It can be understood that the rotating rod 32 can be a variable-diameter structure, one end of which is a smaller-diameter arc surface, and the other end of which is a larger-diameter arc surface. The smaller-diameter arc surface is fixedly installed on the second rotating shaft 31, and the larger-diameter arc surface is provided with a limiting column and a fixed plate. One end of the limiting column is fixedly installed on the larger-diameter arc surface, and the other end of the limiting column passes through the long hole 331 and is connected with the fixed plate. The fixed plate is used to limit the limiting column in the long hole 331. The diameter of the limiting column is slightly smaller than the width of the long hole 331. By arranging the limiting column and the fixed plate, the connection between the rotating rod 32 and the limiting rod 33 can be achieved while the limiting column can move along the long hole 331, so that the rotating rod 32 can drive the limiting rod 33 to swing back and forth with the first rotating shaft 23 as the center and the length of the limiting rod 33 as the radius while rotating. At the same time, since the limiting rod 33 also drives the water spraying rod 22 to swing synchronously when it swings, the water spraying rod 22 is driven to cut the soil by spraying high-pressure water column while swinging. This swinging cutting can increase the cutting range of the water spraying rod 22 without changing the number of water outlets, thereby improving the practicability.

[0035] The driving member can further be provided with a gear one 41, and the rotating shaft two 31 is fixedly provided with a gear two 34 engaged with the gear one 41, and the gear two 34 is fixedly installed on the rotating rod 32 away from the limiting rod 33. The two gears two 34 on the two driven members 3 are respectively arranged on the two sides of the gear one 41. The driving member drives the rotating shaft two 31 to rotate through the engagement of the gear one 41 and the gear two 34, and the rotating shaft two 31 drives the rotating rod 32 to rotate. When the rotating rod 32 rotates, the limiting rod 33 can be driven to reciprocate, and the water spraying rod 22 can be driven to swing through the swing of the limiting rod 33. The swing of the water spraying rod 22 can increase the spraying range of the spray hole on the water spraying rod 22, thereby increasing the cutting range of the high-pressure water column sprayed out of the spray hole, improving the cutting efficiency, and solving the problem of low cutting efficiency caused by the small cutting range of the water spraying rod 22 in the prior art.

[0036] In the embodiment, the driving member can be a driving member driven by a water source. By selecting high-pressure water as the power source, the problem of complex structure in the mother pile 1 caused by the need to set up an electric circuit structure or a pneumatic structure as the power source is solved. At the same time, the selection of high-pressure water as the power source enables the water after the impeller 44 to be discharged to the soil through the bottom of the mother pile 1, and this part of water can cooperate with the high-pressure water discharged from the spray hole of the water spraying rod 22 to cut the soil, further improving the cutting efficiency of the punching mechanism in the embodiment. When the driving member is driven by a water source, the driving member includes a water inlet pipe three 42, a rotating shaft three 43, and an impeller 44. The rotating shaft three 43 is transversely installed in the mother pile 1 through a bearing. The impeller 44 is fixedly installed on the rotating shaft three 43, and the water inlet pipe three 42 is vertically installed in the mother pile 1, and the water outlet of the water inlet pipe three 42 is aligned with the impeller 44. In this embodiment, by conveying high-pressure water into the water inlet pipe three 42, the high-pressure water can impact the impeller 44, so that the impeller 44 drives the rotating shaft three 43 to rotate, and the rotating shaft three 43 drives the gear one 41 to rotate. The gear one 41 and the gear two 34 are engaged to drive the rotating shaft two 31 to rotate, and the rotating shaft two 31 drives the rotating rod 32 to rotate. The rotating rod 32 drives the limiting rod 33 to swing under the rotation of the rotating rod 32, and the water spraying rod 22 swings synchronously with the limiting rod 33 under the action of the rotating shaft one 23. This swinging cutting can increase the cutting range of the high-pressure water column sprayed out of the spray hole on the water spraying rod 22 on the soil below the mother pile 1 without changing the structure of the water spraying rod 22 itself, thereby improving the cutting efficiency and the cutting effect.

[0037] Please refer to Figure 3The water outlet groove 12 is arranged below the impeller 44, and is used to deliver the water passing through the impeller 44 to the soil to be cut through the bottom of the mother pile 1. Through the arrangement of the water outlet groove 12, the water discharged by the impeller 44 can be utilized, so that the water discharged by the impeller 44 can flow into the soil through the water outlet groove 12, so that the water as a power source can also disperse the soil, and in cooperation with the spray holes on the water spray rods 22 on the two sides, the soil can be quickly and effectively cut, so as to achieve the purposes of hole expansion and hole guiding.

[0038] It can be understood that, in the length direction of the mother pile 1, the water outlet groove 12 and the water inlet pipe three 42 are arranged on the two sides of the rotating shaft three 43. Through this arrangement, under the rotation of the impeller 44, the water passing through the impeller 44 can flow into the water outlet groove 12 under the action of inertia, so that this part of the water can also cut the soil at the bottom of the mother pile 1 through the water outlet groove 12, further improving the cutting effect of the whole hole drilling mechanism on the soil.

[0039] Please refer to Figure 5 and Figure 6 Under the rotation of the rotating rod 32, the rotating rod 32 can drive the water spray rod 22 to swing left or right through the limiting rod 33. When the high-pressure water in the water inlet pipe three 42 is sprayed to the impeller 44, the impeller 44 rotates by driving the gear one 41, and the gear one 41 simultaneously drives the two gear twos 34 to rotate, so that the rotating rod 32 rotates. At this time, the limiting rod 33 located in the middle can first drive the water spray rod 22 to swing left, and then drive the water spray rod 22 to swing right under the action of the rotating rod 32. The specific swinging process of the water spray rod 22 can be referred to Figure 6 . Among them, Figure 6 The blue part is the spray range of the spray hole.

[0040] In this embodiment, the driving member can also be a driving motor, and the output shaft of the driving motor is connected with the gear one 41. The gear one 41 is driven to rotate by the driving motor, and the gear one 41 drives the two gear twos 34 located on the two sides to rotate in the same direction. The same direction rotation of the two gear twos 34 can drive the two limiting rods 33 to swing in the same direction, and the two limiting rods 33 drive the two water spray rods 22 to swing in the same direction. Through this arrangement, the swinging directions of the two water spray rods 22 are consistent, which can avoid the problem that the cutting water columns sprayed by the spray holes of the two water spray rods 34 collide in opposite directions when the two spray holes are rotated to the direction close to the driving member, thereby reducing the cutting force of the high-pressure water columns sprayed by the two spray holes.

[0041] It can be understood that the water spray member can also include a water delivery tank 24, please refer to Figure 2 and Figure 7The water delivery tank 24 is installed in the mother pile 1 and above the perforating mechanism. Please refer to Figure 7 The water delivery tank 24 is provided with a second water inlet pipe 241, a second water outlet pipe 243 and two first water outlet pipes 242. The second water inlet pipe 241 is installed on the upper end surface of the water delivery tank 24 and used to deliver high-pressure water from outside to the water delivery tank 24. The second water outlet pipe 243 and the two first water outlet pipes 242 are arranged on the lower end surface of the water delivery tank 24. The second water outlet pipe 243 is detachably connected to the third water inlet pipe 42, and each first water outlet pipe 242 is detachably connected to each first water inlet pipe 21. By arranging the water delivery tank 24, high-pressure water from outside can be delivered to the third water inlet pipe 42 and the two first water inlet pipes 21. The second water inlet pipe 241 is used to deliver high-pressure water from outside to the water delivery tank 24, and the high-pressure water in the water delivery tank 24 is sprayed out through three water paths. The first water path is that the high-pressure water is sprayed out through the second water outlet pipe 243 and the third water inlet pipe 42 to the impeller 44. The high-pressure water in this path can be used as a power source to drive the impeller 44 to rotate under the action of the water column sprayed out from the third water inlet pipe 42. The impeller 44 drives the two gear wheels II 34 to rotate in the same direction through the gear I 41, and drives the two rotating rods 32 to rotate through the meshing of the gear I 41 and the gear wheel II 34. The second water path is that the high-pressure water enters the spray hole of the spray rod 22 through the first water outlet pipe 242 and the first water inlet pipe 21, and is sprayed out to form a water column. This water path is a cutting water path. The rotating rod 32 drives the limiting rod 33 to reciprocate, and the limiting rod 33 drives the spray rod 22 to reciprocate to increase the spray range of the spray hole on the spray rod 22 without changing the structure of the spray rod 22, thereby increasing the cutting range of the high-pressure water column sprayed out through the spray hole on the soil below the mother pile 1, and improving the cutting efficiency and effect of the perforating mechanism.

[0042] It can be understood that in the embodiment, a groove is installed on one side of the mother pile 1 close to the upper end surface of the mother pile 1. The size of the groove is the same as that of the water delivery tank 24, so that the water delivery tank 24 can be placed in the groove. The second water outlet pipe 243 on the water delivery tank 24 is detachably connected to the third water inlet pipe 42, and the first water outlet pipe 242 on the water delivery tank 24 is also detachably connected to the first water inlet pipe 21. At least one pressing plate 11 is rotatably installed on the upper end surface of the mother pile 1, and the pressing plate 11 abuts against the upper end of the water delivery tank 24. The pressing plate 11 and the water delivery tank 24 are connected through threads.

[0043] Further, in the embodiment, please refer to Figure 7The water outlet end of the second water outlet pipe 243 is inserted into the water inlet end of the third water inlet pipe 42, and the water outlet end of the first water outlet pipe 242 is inserted into the water inlet end of the first water inlet pipe 21. In actual application, the water delivery tank 24 and the mother pile 1 are detachable, so that the water delivery tank 24 and the mother pile 1 can be disassembled and stored during actual transportation, facilitating transportation of the water delivery tank 24 and the mother pile 1. In use, the second water outlet pipe 243 is aligned with the third water inlet pipe 42, and the two first water outlet pipes 242 are respectively aligned with the two first water inlet pipes 21, and then the water delivery tank 24 is placed in the mounting groove. The pressing plate 11 is rotated to be pressed on the upper end surface of the water delivery tank 24, and the pressing plate 11 and the water delivery tank 24 are fixed by bolts, so as to fix the water delivery tank 24 in the mounting groove.

[0044] In the embodiment, please refer to Figure 2 The number of the pressing plates 11 can be two, and the two pressing plates 11 are symmetrically mounted on the upper end surface of the mother pile 1. When the water delivery tank 24 is mounted, the two pressing plates 11 can be first rotated to be vertical, and the distance between the two pressing plates 11 is greater than the distance of the mounting groove in the width direction of the mother pile 1. At this time, the water delivery tank 24 can be placed in the mounting groove, and then the pressing plates 11 are rotated to be horizontal, so that the lower end surface of the pressing plates 11 abuts against the upper end surface of the water delivery tank 24.
