Description

Technical Field

[0001] The utility model belongs to the technical field of engineering equipment, and particularly relates to a vibrating sand pile. Background Art

[0002] A sand pile is a sand column formed by using methods such as impact or vibration to sink a steel casing into the foundation soil at a certain interval to form a hole, and then filling sand into the pipe while pulling out the pipe and vibrating it densely. A vibrating sand pile is a tool for preparing sand piles by using methods such as impact or vibration.

[0003] However, due to the uneven distribution of foundation soil layers, in addition to loose sandy soil in the construction area, there are also some soil layers with relatively high density. If the traditional flap pile tip type is used, its opening and closing structure is easily damaged during the pile driving process, resulting in the inability to perform sand filling operation after the hole is formed. Moreover, the opening and closing structure of the traditional pile tip flap is directly stressed during the pipe sinking process and is easily damaged in relatively hard soil layers, resulting in the inability to open during lifting. When constructing in silt soil with relatively high consistency, the opening and closing structure is also easily blocked by silt, resulting in poor opening and closing effects and affecting the construction efficiency.

Figure 2 is a schematic structural diagram of a drill bit assembly according to an embodiment of the present utility model. Figure 3 is a schematic bottom view of a drill bit assembly according to an embodiment of the present utility model. Figure 4 is a schematic installation diagram of a drill bit assembly and a hollow casing according to an embodiment of the present utility model.

[0038] Such as Figure 1As shown in the figure, the present utility model provides a vibrating sand pile 100. The vibrating sand pile 100 includes a vibrating hammer 10, a hollow casing 20 and a drill bit assembly 30. The hollow casing 20 extends in the vertical direction. A grouting channel 21 is provided in the middle of the hollow casing 20. The top of the grouting channel 21 is fixedly connected to the bottom of the vibrating hammer 10. The drill bit assembly 30 includes a main body portion 31. An installation groove 311 is provided at the top of the main body portion 31. The main body portion 31 is in an inverted conical structure. The installation groove 311 is connected to the bottom of the grouting channel 21. At least one sand discharge channel 312 is provided in the main body portion 31. One end of the sand discharge channel 312 communicates with the grouting channel 21, and the other end penetrates the outer side wall 313 of the main body portion 31 and forms a sand discharge hole 314 at the outer side wall 313 of the main body portion 31. That is to say, the vibrating sand pile 100 includes the vibrating hammer 10, the hollow casing 20 and the drill bit assembly 30 arranged in sequence from top to bottom. The vibrating hammer 10 is connected to the hollow casing 20. The hollow casing 20 is connected to the installation groove 311 at the top of the drill bit assembly 30. The vibrating hammer 10 is used to apply a vibration force perpendicular to the ground to the drill bit assembly 30 so that the drill bit assembly 30 drills towards the ground. And a sand discharge channel 312 is provided in the main body portion 31 of the drill bit assembly 30. One end of the sand discharge channel 312 communicates with the grouting channel 21, and the other end penetrates the outer side wall 313 of the main body portion 31 and forms a sand discharge hole 314 at the outer side wall 313 of the main body portion 31. When the drill bit assembly 30 moves to the target depth and forms a drill hole, mortar is injected from the hollow casing 20 so that the mortar flows into the grouting channel 21 and the sand discharge channel 312 in sequence until it flows into the drill hole through the sand discharge hole 314 on the side wall of the main body portion 31. Then the drill bit assembly 30 is slowly moved upward until the drill bit assembly 30 of the vibrating sand pile 100 completely leaves the drill hole. Here, the connection between the hollow casing 20 and the installation groove 311 of the main body portion 31 is a rotational connection. In other embodiments, the connection between the hollow casing 20 and the installation groove 311 of the main body portion 31 is a snap connection.

[0039] As Figure 2 shown in the figure, in this embodiment, by providing a drill bit assembly 30 with an inverted conical structure at the bottom of the vibrating sand pile 100, and arranging a sand discharge channel 312 and a sand discharge hole 314 corresponding to the sand discharge channel 312 in the drill bit assembly 30, the drill bit assembly 30 with an inverted conical structure can withstand the large force provided by the vibrating hammer 10, and at the same time can reduce the resistance of the drill bit assembly 30 to form a drill hole towards the ground, making the penetration power of the drill bit assembly 30 better, thereby improving the structural stability and drilling efficiency of the vibrating sand pile 100 and avoiding damage to the drill bit assembly 30 in a hard soil foundation. Here, the material of the drill bit assembly is steel.

[0040] In one embodiment, the vibrating hammer 10 of the vibrating sand pile 100 is fixedly connected to the sand pile machine. The vibrating hammer 10 is located at the bottom of the sand pile machine. The sand pile machine is used to control the opening or closing of the vibrating hammer 10. After the drill bit assembly 30 of the vibrating sand pile 100 is aligned with the center pile position, the vibrating hammer 10 is started for pipe sinking construction, that is, the vibrating hammer 10 is controlled to apply a force to the hollow casing 20. After the vibrating sand pile 100 reaches the specified depth, mortar perfusion is controlled. After the mortar perfusion is completed, the sand pile machine controls the lifting of the hollow casing 20 and the drill bit assembly 30, so that the mortar fills the pile hole under the action of gravity until it is pulled out of the ground.

[0041] Figure 5 is a schematic structural diagram of a sand hole plug according to an embodiment of the present invention. Figure 6 is a schematic installation diagram of a drill bit assembly and a sand hole plug according to an embodiment of the present invention.

[0042] As Figure 5 shown, in a further embodiment, the drill bit assembly 30 further includes a sand hole plug 32 corresponding to each row of sand channels 312. The sand hole plug 32 is used to block the sand channels 312 when the drill bit assembly 30 drills, and to disengage from the sand channels 312 during grouting. Each sand hole plug 32 is correspondingly arranged with a sand channel 312, that is, each sand hole plug 32 is used to block each sand channel 312 when the drill bit assembly 30 drills, so as to block the sand discharge holes 314 arranged corresponding to each sand channel 312, and prevent the loose soil generated during the drilling of the drill bit assembly 30 from entering the sand channels 312 through the sand discharge holes 314, thereby avoiding the blockage of the sand channels 312, and further avoiding the situation that the subsequent mortar cannot be poured into the drill hole. And during grouting, the sand hole plug 32 is removed, so that the mortar is poured into the drill hole along the grouting channel 21 and the sand channel 312 in sequence, avoiding the mixing of the loose soil entering the sand channel 312 with the mortar and affecting the quality of the grouted sand pile, thereby improving the grouting rate and grouting quality of the vibrating sand pile 100.

[0043] As Figure 5As shown, in a further embodiment, the drill bit assembly 30 further includes at least one connecting line 33, one end of which is fixedly connected to the sand hole plug 32, and the other end forms an operating end 331, so that when the operating end 331 is subjected to a tensile force, the sand hole plug 32 is driven to move out of the sand discharge channel 312 in a direction away from the sand discharge hole 314. By providing the connecting line 33 and fixedly connecting one end of the connecting line 33 to the sand hole plug 32, when the operating end 331 of the connecting line is subjected to a tensile force, the sand hole plug 32 can be driven to move out of the sand discharge channel 312 in a direction away from the sand discharge hole 314 and move out of the grouting channel 21. That is, after the vibrating sand pile 100 reaches the designated depth, the operating end 331 of the connecting line is stressed to apply a tensile force to the sand hole plug 32, so that the sand hole plug 32 passes through the sand discharge channel 312 and the grouting channel 21 in sequence, and finally moves out of the vibrating sand pile 100. That is to say, the sand hole plug 32 can be arranged in the sand discharge channel 312 to prevent the loose soil from blocking the sand discharge channel 312, and the sand hole plug 32 can also be moved out of the sand discharge channel 312 by using the connecting line during grouting. The setting structure of the connecting line and the sand hole plug 32 in this embodiment is simple and the operation is convenient, which can effectively avoid the influence of the loose soil generated by the drilling of the drilling assembly on grouting. Here, the number of the connecting lines 33 can be one or more.

[0044] In one embodiment, the number of the connecting lines 33 is multiple, and each connecting line 33 is fixedly connected to a sand hole plug 32. By selecting the stretched connecting line 33, the sand hole plug 32 correspondingly arranged with the connecting line 33 can be moved out, so that the mortar grouts into the drill hole from the sand discharge channel 312 where the sand hole plug 32 is moved out, so as to form a sand pile at a specific position in the drill hole, thereby improving the flexibility of forming the sand pile of the vibrating sand pile 100.

[0045] As Figure 5 shown, in a further embodiment, a through hole 321 for connecting the connecting line 33 is provided at one end of the sand hole plug 32, and a matching surface 322 is formed at the other end of the sand hole plug 32. When the sand hole plug 32 is arranged in the sand discharge channel 312, the matching surface 322 is flush with the sand discharge hole 314. The connecting line 33 is passed through the through hole to be fixedly connected to the sand hole plug 32, so that the connection between the connecting line 33 and the sand hole plug 32 is firm, and the connecting line 33 is prevented from falling off from the sand hole plug 32 when being stressed and stretched, thereby avoiding affecting the grouting efficiency of the vibrating sand pile 100. A matching surface 322 flush with the sand discharge hole 314 is provided at the other end of the sand hole plug 32, that is, to prevent the sand hole plug 32 from protruding from the sand discharge hole 314, and to avoid the surface resistance of the main body 31 of the drill bit assembly 30 from increasing due to the matching surface 322 of the sand hole plug 32 protruding from the main body 31, thereby avoiding affecting the drilling efficiency of the vibrating sand pile 100 and preventing the sand hole plug 32 from protruding from the sand discharge hole 314. At the same time, the sand hole plug 32 is provided with a matching surface 322 flush with the sand discharge hole 314, which can prevent the sand hole plug 32 from not completely blocking the sand discharge channel 312, and avoid the loose soil from entering the sand discharge channel 312, thereby avoiding the loose soil from affecting the grouting efficiency and the quality of the sand pile.

[0046] As Figure 5 shown, in a further embodiment, a clamping portion 323 is provided at one end of the sand hole plug 32 close to the through hole 321. The clamping portion 323 has a clamping surface 324 facing the sand discharge hole 314. The main body portion 31 is provided with a receiving surface corresponding to each clamping surface 324 and facing the grouting channel 21. The clamping surface 324 extends in the horizontal direction, the receiving surface extends in the horizontal direction, and the clamping surface 324 is arranged to face the sand discharge hole 314, and the receiving surface is arranged to face the grouting channel 21, that is, the receiving surface is used to support the clamping surface 324 to prevent the sand hole plug 32 from sliding off from the sand discharge hole 314 along the sand discharge channel 312, and ensure the stability of the sand hole plug 32 in the sand discharge channel 312.

[0047] As Figure 1 shown, in a further embodiment, the hollow casing 20 further includes a feed port 22 for pouring slurry. The feed port 22 is arranged on the side wall of one end of the hollow casing 20 far from the drill bit assembly 30. The operating end 331 of the connecting line 33 is arranged to extend out of the feed port 22. The feed port 22 is arranged on the side wall of the top of the hollow casing 20 for pouring mortar into the hollow casing 20. The feed port 22 is arranged at the top end of the hollow casing 20. Since the hollow casing 20 itself has a certain height, the feed port 22 is arranged at the top end of the hollow casing 20, so that the mortar poured from the feed port 22 flows through the grouting channel 21 and the sand discharge channel 312 by its own gravity and accelerates, until it flows into the drill hole from the sand discharge hole 314, and the mortar is vibrated under the action force applied by the vibratory hammer 10 to discharge the air inside the mortar, thereby compacting the mortar and improving the stability and quality of the sand pile.

[0048] In a further embodiment, the axial direction of the sand discharge channel 312 is parallel to the axial direction of the main body portion 31. The main body portion 31 is arranged such that its axis extends in the vertical direction, and the sand discharge channel 312 is arranged such that its axial direction is parallel to the axial direction of the main body portion 31, that is, the axial direction of the sand discharge channel 312 extends in the vertical direction, and the sand discharge channel 312 is correspondingly arranged with the grouting channel 21, so that when the mortar flows from the grouting channel 21 into the sand discharge channel 312, the mortar can always be accelerated and injected into the drill hole by its own gravity, thereby improving the grouting efficiency of the vibratory sand pile 100.

[0049] In a further embodiment, the number of the sand discharge channels 312 is multiple, and the multiple sand discharge channels 312 are uniformly arranged along the circumferential direction of the main body portion 31. The multiple sand discharge channels 312 can improve the grouting efficiency of the vibratory sand pile 100. The multiple sand discharge channels 312 are uniformly arranged along the circumferential direction of the main body portion 31, so that when the mortar flows from the sand discharge channel 312 into the drill hole, the mortar is evenly distributed, thereby forming a sand pile with uniform mortar content and improving the quality of the sand pile prepared by the vibratory sand pile 100.

[0050] In one embodiment, the number of connecting lines 33 is one. One connecting line 33 is connected to a plurality of sand hole plugs 32, so that when the operating end 331 of the connecting line 33 is subjected to a tensile force, a plurality of sand hole plugs 32 can be simultaneously removed from the sand discharge channel 312 and the grouting channel 21, thereby improving the grouting efficiency of the vibrating sand pile 100.

[0051] In a further embodiment, the main body portion 31 is an inverted cone structure. The inverted cone structure makes the side wall surface of the main body portion 31 smooth, reduces the resistance when the drill bit assembly 30 forms a drill hole, thereby improving the drilling efficiency of the drill bit assembly 30 and the working efficiency of the vibrating sand pile 100. At the same time, the inverted cone structure enhances the stability of the mechanical structure of the drill bit assembly 30, and can avoid the drill bit assembly 30 from being damaged when operating on a hard soil foundation, thereby improving the use safety of the vibrating sand pile 100. In other embodiments, the main body portion 31 may also be an inverted triangular pyramid structure.

[0052] In a further embodiment, the angle of the main body portion 31 is any value within the range of 45° - 60°. Specifically, the angle of the main body portion 31 can be 45°, 50°, 55° or 60°, or any other value within 45° - 60°. When the angle of the main body portion 31 of the vibrating sand pile 100 is within the above range, it can better adapt to various soil conditions, improve the construction efficiency, and at the same time can reduce the disturbance to the surrounding soil during the construction process, which is beneficial to protecting the surrounding environment. Unsuitable angles may lead to an increase in the disturbance to the soil during the construction process and affect the construction quality. When the angle of the main body portion 31 is greater than 60° or less than 45°, the bearing capacity of the vibrating sand pile 100 decreases, that is, insufficient or excessive drill bit angles may affect the bearing capacity of the pile body, thereby affecting the stability and safety of the project.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
