Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a civil engineering composite pile. Background Art

[0002] Composite piles in civil engineering are an important part of the operation of housing construction sites. According to the relative ratio of the side friction resistance and end resistance provided by the soil, engineering piles can be divided into four categories: friction piles, end-bearing piles, end-bearing friction piles and friction end-bearing piles. According to the size of the pile diameter, the piles can be divided into three categories: large-diameter piles, medium-diameter piles and small-diameter piles. According to the pile body material, the piles can be divided into concrete piles, wooden piles, steel piles and composite piles. According to the different pile-forming methods, they can be divided into three types: soil-squeezing piles (such as driven precast piles), partially soil-squeezing piles (such as pre-drilled and driven precast piles) and non-squeezing piles (such as bored and cast-in-place piles). According to the construction method, the piles can be divided into two categories: precast piles and cast-in-place piles.

[0003] Composite piles need to be driven into the soil layer with the help of external force to ensure stability during subsequent civil engineering construction. However, after the composite piles are pressed into the soil layer, since the outer wall of the composite piles in the prior art is smooth, they are fixed by friction with the soil and cannot be fixed by external force, which easily causes the composite piles to tilt and have poor stability.

[0049] Composite piles need to be driven into the soil with the help of external force to ensure stability during subsequent civil engineering construction, but after the composite piles are pressed into the soil, they are fixed by the friction with the soil.

[0050] In the related art, the outer wall of the composite pile is smooth, and the fixing stability is poor if it only relies on the friction between the outer walls, which can easily cause the composite pile to tilt and be easy to pull out, and even affect the normal supporting effect of the composite pile.

[0051] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a civil engineering composite pile. When the pile body 11 needs to be fixed, it is only necessary to use the driving mechanism 27 to drive the screw rod 21 to rotate, so that the threaded sleeve 24 gradually approaches the fixed seat 23, and the bottom plate 22 supports the fixed seat 23. When the threaded sleeve 24 approaches the fixed seat 23, the connecting rod 25 hinged on the outside of the threaded sleeve 24 gradually tilts from vertical to horizontal, and the top of the fixed plate 26 hinged at one end of the connecting rod 25 is pushed by the connecting rod 25 to tilt outward until it extends out of the through groove 13, thereby increasing the contact area with the soil layer and preventing the pile body 11 from being easily pulled out or even tilted, thereby affecting the stability of the pile body 11.

[0052] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0053] Combination Figure 1-Figure 6 The embodiment of the present application provides a civil engineering composite pile, including a main body component 1, the main body component 1 includes: a drill bit 12 is arranged at the bottom of the pile body 11, a through groove 13 is arranged on the outside of the pile body 11, and a fixing component 2 is arranged on the pile body 11, and the fixing component 2 includes: a screw rod 21 is arranged inside the pile body 11, a bottom plate 22 is arranged on the inner wall of the pile body 11, a fixing seat 23 is arranged on the top of the bottom plate 22, and the bottom end of the screw rod 21 is rotatably connected with the fixing seat 23, a threaded sleeve 24 is sleeved on the outside of the screw rod 21 and is threadedly connected with the screw rod 21, a connecting rod 25 is arranged on the outside of the threaded sleeve 24, a fixing plate 26 is arranged on the outside of the fixing seat 23, one end of which is connected to the fixing seat 23 by a hinge, and one end of the connecting rod 25 is hinged to the threaded sleeve 24, and the other end is hinged to the fixing plate 26, and a driving mechanism 27 is arranged on the screw rod 21.

[0054] When a building in a civil engineering project needs to be piled to ensure the stability of the building, the pile body 11 is placed on the ground, and the drill bit 12 is used to drill into the soil layer. After the pile body 11 is buried to a certain depth, the fixing component 2 is used to fix the pile body 11: first, the driving mechanism 27 is used to drive the screw rod 21 to rotate. When the screw rod 21 rotates, the threaded sleeve 24 threaded thereon moves up and down according to the different rotation directions of the screw rod 21. The rotation direction of the screw rod 21 is controlled so that the threaded sleeve 24 gradually approaches the fixing seat 23, and the bottom plate 22 supports the fixing seat 23. When the threaded sleeve 24 approaches the fixing seat 23, the connecting rod 25 hinged on the outside of the threaded sleeve 24 gradually tilts from vertical to horizontal, and the top of the fixing plate 26 hinged at one end of the connecting rod 25 is pushed by the connecting rod 25 to tilt outward until it extends out of the through groove 13, thereby increasing the contact area with the soil layer and preventing the pile body 11 from being easily pulled out or even tilted, thereby affecting the stability of the pile body 11. When the pile body 11 tilts during piling or a building in a civil engineering project needs to be demolished, the pile body 11 needs to be pulled out, and the screw rod 21 is rotated in the opposite direction, and the threaded sleeve 24 drives the connecting rod 25 to retract the fixing plate 26, so as to facilitate the pulling out of the pile body 11.

[0055] Specifically, since one end of the screw rod 21 is rotatably connected to the fixed seat 23, when the screw rod 21 rotates, the external hinged fixing plate 26 of the fixed seat 23 limits the movement of the connecting rod 25, and the connecting rod 25 is connected to the threaded sleeve 24, so that the threaded sleeve 24 cannot rotate with the rotation of the screw rod 21, thereby avoiding affecting the normal extension or retraction of the fixing plate 26.

[0056] In some embodiments, the driving mechanism 27 includes: a hexagon socket bolt 271 disposed on the top of the screw rod 21, a hexagonal rod 272 disposed on the hexagon socket bolt 271, the hexagon socket bolt 271 is used in conjunction with the hexagonal rod 272, and a turning handle 273 is disposed on the top of the hexagonal rod 272.

[0057] The use process of the driving mechanism 27 is as follows: the operator inserts the bottom end of the hexagonal rod 272 into the hexagonal bolt 271 and turns the handle 273. The handle 273 drives the hexagonal rod 272 to rotate, and then drives the hexagonal bolt 271 and the screw rod 21 to rotate, thereby completing the extension or retraction of the fixing plate 26.

[0058] Specifically, the head of the hexagon socket bolt 271 is a hexagon socket head, the hexagonal rod 272 is a stainless steel rod with a regular hexagonal cross-section, the hexagonal rod 272 and the hexagon socket bolt 271 are of separate design, the hexagonal rod 272 can be pulled out of the hexagon socket bolt 271, and the operator can fix different pile bodies 11 as needed.

[0059] In some embodiments, the fixing plates 26 are distributed around the circumference and are provided at multiple locations. The fixing plates 26 are provided at multiple locations to increase the contact area with the soil layer in multiple directions, thereby enhancing the stability of the pile body 11 .

[0060] In some embodiments, the top of the fixed plate 26 is rotatably connected to an accordion protective cover 28 through a rotating rod, and the top of the accordion protective cover 28 is connected to the through slot 13 opened on the pile body 11. The accordion protective cover 28 is in a straight line shape and is made of nylon leather, plastic fabric or synthetic rubber by folding, sewing or hot pressing, and is supported by a PVC sheet inside. The accordion protective cover 28 has a certain telescopic performance and can stretch freely with the movement of the force-bearing object. When the fixed plate 26 extends out of the through slot 13, the bottom end of the accordion protective cover 28 rotates along the connection with the fixed plate 26, and the accordion protective cover 28 extends to cover the top of the fixed plate 26 to prevent soil from adhering to the fixed plate 26. When the fixed plate 26 is retracted, the soil is brought into the pile body 11.

[0061] In some embodiments, a groove 261 is provided on the connecting rod 25. When the threaded sleeve 24 drives the connecting rod 25 to move upward, the bottom end of the connecting rod 25 is retracted into the groove 261, so that the fixing plate 26 remains in a vertical state. When the fixing plate 26 is in a vertical state, it abuts against the inner wall of the through groove 13. The accordion protective cover 28 rotatably connected at the top and the fixing plate 26 jointly block the through groove 13 to prevent soil from entering the pile body 11 from the through groove 13.

[0062] In some embodiments, a connecting assembly 3 is provided on the pile body 11, and the connecting assembly 3 includes: a connecting rod 31 provided on the top of the pile body 11, a sliding block 32 provided on the connecting rod 31, a slide groove 1 33 provided on the inner wall of the pile body 11, and a slide groove 2 34 provided on the inner wall of the pile body 11 and located above the slide groove 1 33.

[0063] When the pile body 11 is driven into the soil layer and found to be insufficient in height, the connecting assembly 3 is used to quickly connect the pile bodies 11: the second pile body 11 installed later is inserted into the top of the first pile body 11 that has been completed, and the connecting rod 31 at the top of the first pile body 11 drives the sliding block 32 on the side of the connecting rod 31 close to the pile body 11 to extend into the bottom of the second pile body 11 through the slide groove 1 33. At this time, the sliding block 32 enters the slide groove 2 34, and the second pile body 11 is rotated so that the sliding block 32 slides in the slide groove 2 34 and away from the top of the slide groove 1 33. At this time, the second pile body 11 cannot be pulled out of the first pile body 11, and the quick connection between the pile bodies 11 is completed. When the pile body 11 needs to be dismantled, the top pile body 11 is rotated so that the sliding block 32 is aligned with the top of the slide groove 1 33, and the operator takes out the top pile body 11 to complete the disassembly of the pile body 11.

[0064] In some embodiments, a positioning line 35 is provided on the outside of the pile body 11. The positioning line 35 and the connecting rod 31 are located on the same axis. The positioning line 35 is a strip-shaped protrusion. When the top of the pile body 11 is aligned with the positioning line 35 of another pile body 11, the connecting rod 31 and the slider 32 are just in the slide groove 33, which makes it convenient for the operator to know the rotation position of the slider 32 inside the pile body 11, and facilitates the connection and disassembly of the pile body 11.

[0065] In some embodiments, the length of the through slot 13 is greater than that of the fixing plate 26 , so that the through slot 13 does not restrict the movement of the fixing plate 26 .

[0066] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0067] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
