Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and in particular to a cantilever pile support structure. Background Technology

[0002] In building construction, cantilever pile support structures are widely used in slope and foundation pit support. They are a structural form consisting of manually excavated piles or bored cast-in-place piles arranged in a straight line and connected by retaining plates to jointly resist lateral earth pressure or sliding force. However, existing cantilever pile support structures are too simple and have poor anti-tilting ability. Therefore, they are easily tilted by the squeezing action of the soil inside the foundation pit during use, which can lead to foundation pit collapse in severe cases.

[0003] Chinese Patent Publication No. CN202543966U discloses a pile-supported cantilever retaining wall, which can solve the problem of insufficient foundation bearing capacity to meet base stress without increasing the size of the base plate, and improve the beneficial effects of overturning resistance and sliding resistance. However, in actual use, the piles at the bottom of the cantilever pile wall of this patent are prone to tilting after being fixed, which can lead to the collapse of the foundation pit in severe cases. Although there are other patent documents that have made improvements, the structure was more complicated at that time. Therefore, this application provides a cantilever pile support structure. Utility Model Content

[0004] The purpose of this utility model is to provide a cantilever pile support structure that is simple in structure and provides effective protection.

[0005] This utility model is achieved through the following measures:

[0006] A cantilever pile support structure, characterized in that it includes a base plate, on which a pile body is fixed, a support mechanism is provided between the pile body and the base plate, and an inclined rod that is inclinedly inserted into the ground is provided on the base plate;

[0007] The support mechanism includes a main rod and a sleeve movably disposed around the main rod. The upper end of the main rod is disposed on the inner side of the pile body, and the lower end of the sleeve is disposed on the base plate.

[0008] The specific features of this utility model also include:

[0009] The main rod is provided with an external thread, and the inner wall of the sleeve is provided with an internal thread that mates with the external thread. The sleeve is movably fitted around the main rod through the threaded structure.

[0010] An inclined end is provided on the inner side of the pile body, and a rectangular groove is provided on the corresponding end face of the inclined end. A corresponding insert block is provided on the upper end face of the main rod to cooperate with the rectangular groove. The insert block is inserted into the rectangular groove.

[0011] A locking bolt is provided on the outer side of the inclined end one, which passes through the rectangular groove one. The insert block is provided with a hole that mates with the locking bolt. The head of the locking bolt is located in the hole. When the insert block is inserted into the rectangular groove one, it is fixed by the locking bolt.

[0012] The base plate is provided with an inclined end two corresponding to the inclined end one. The end face of the inclined end two is provided with a circular groove that mates with the sleeve. An inclined hole that passes through the base plate is coaxially provided on the bottom surface of the circular groove. The inclined rod is provided in the inclined hole.

[0013] The inclined rod includes a round rod and a tapered end at the lower end of the round rod. The outer periphery of the round rod is provided with an external thread, and the inner wall of the inclined hole is provided with an internal thread that mates with the external thread. The inclined rod mates with the inclined hole through the threaded structure. Rotating the inclined rod allows it to be inserted obliquely into the ground to further fix the base plate.

[0014] The lower end of the sleeve is provided with a sealing block, and the sealing block is provided with a rectangular groove two. The upper end face of the round rod is provided with a rectangular groove three symmetrical to the rectangular groove two. A rectangular connecting block is movably arranged between the rectangular groove two and the rectangular groove three. After the upper end of the support mechanism is fixed by the locking bolt, the sleeve is rotated, and the sleeve moves downward close to the inclined rod. Then, the rectangular connecting block is placed into the rectangular groove two. The sleeve is rotated again to shorten the distance with the inclined rod. Then, by rotating the sleeve, the... Align the rectangular connecting block with the rectangular groove three below, then slide the lower end of the rectangular connecting block into the rectangular groove three to connect the sleeve and the inclined rod. Then rotate the sleeve to rotate the inclined rod, thereby inserting the inclined rod into the ground. When the lower end of the sleeve abuts against the bottom surface of the circular groove, it can no longer rotate. At this time, the support mechanism also supports the pile body and the base plate. It should be noted that the thread structure of the inclined rod and the thread structure of the sleeve are matched in the same direction to achieve the same rotation of the sleeve and the inclined rod.

[0017] After the upper end of the support mechanism is fixed by the locking bolt, the rectangular connecting block is temporarily fixed in the rectangular groove two by the pin. Then, the sleeve is rotated by the rotating handle, and the sleeve moves downward to approach the inclined rod. When the distance between them is small enough, the sleeve is rotated to align the rectangular connecting block with the rectangular groove three below. Then, the pin is removed and the lower end of the rectangular connecting block is slid into the rectangular groove three to connect the sleeve and the inclined rod. Then, the sleeve is rotated to rotate the inclined rod, thereby inserting the inclined rod into the ground. When the lower end of the sleeve abuts against the bottom surface of the circular groove, it can no longer rotate. At this time, the support mechanism provides support for the pile and the base plate.

[0028] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0029] See Figures 1-5 A cantilever pile support structure includes a base plate 1, a pile body 2 fixed on the base plate 1, a support mechanism between the pile body 2 and the base plate 1, and an inclined rod 7 that is inclinedly inserted into the ground on the base plate 1.

[0030] The support mechanism includes a main rod 4 and a sleeve 3 that is movably disposed around the main rod 4. The upper end of the main rod 4 is disposed on the inner side of the pile body 2, and the lower end of the sleeve 3 is disposed on the base plate 1.

[0031] The main rod 4 has an external thread 1 on its outer periphery, and the sleeve 3 has an internal thread 1 on its inner wall that mates with the external thread 1. The sleeve 3 is movably fitted around the main rod 4 through the threaded structure.

[0032] An inclined end 5 is inclinedly provided on the inner side of the pile body 2. A rectangular groove 13 is provided on the corresponding end face of the inclined end 5. A plug 16 that mates with the rectangular groove 13 is provided on the upper end face of the corresponding main rod 4. The plug 16 is inserted into the rectangular groove 13.

[0033] A locking bolt 12 is provided on the outer side of the inclined end 5, which passes through the rectangular groove 13. The insert block 16 is provided with a socket that mates with the locking bolt 12. The head of the locking bolt 12 is located in the socket. When the insert block 16 is inserted into the rectangular groove 13, it is fixed by the locking bolt 12.

[0034] The base plate 1 is provided with an inclined end 2 8 corresponding to the inclined end 1 5. The end face of the inclined end 2 8 is provided with a circular groove 14 that cooperates with the sleeve 3. An inclined hole 15 that passes through the base plate 1 is coaxially provided on the bottom surface of the circular groove 14. An inclined rod 7 is provided in the inclined hole 15.

[0035] The inclined rod 7 includes a round rod 19 and a tapered end 20 located at the lower end of the round rod 19. The outer periphery of the round rod 19 is provided with an external thread 2, and the inner wall of the inclined hole 15 is provided with an internal thread 2 that mates with the external thread 2. The inclined rod 7 mates with the inclined hole 15 through the threaded structure. By rotating the inclined rod 7, it can be inserted obliquely into the ground to further fix the base plate 1.

[0036] A sealing block is provided at the lower end of the sleeve 3, and a rectangular groove 17 is provided on the sealing block. A rectangular groove 18, symmetrical to the rectangular groove 17, is provided on the upper end face of the round rod 19. A rectangular connecting block 11 is movably arranged between the rectangular grooves 17 and 18. After the upper end of the support mechanism is fixed by the locking bolt 12, the sleeve 3 is rotated, and the sleeve 3 moves downward to approach the inclined rod 7. Then, the rectangular connecting block 11 is placed into the rectangular groove 17. The sleeve 3 is rotated further to shorten the distance with the inclined rod 7. Then, the rectangular connecting block 11 is moved downward by rotating the sleeve 3. Align the connecting block 11 with the rectangular groove 3 18 below, then slide the lower end of the rectangular connecting block 11 into the rectangular groove 3 18 to connect the sleeve 3 and the inclined rod 7. Then rotate the sleeve 3 to rotate the inclined rod 7, thereby inserting the inclined rod 7 into the ground. When the lower end of the sleeve 3 abuts against the bottom surface of the circular groove 14, it can no longer rotate. At this time, the support mechanism also supports the pile body 2 and the base plate 1. It should be noted that the thread structure of the inclined rod 7 and the thread structure of the sleeve 3 are matched in the same direction to achieve the same rotation of the sleeve 3 and the inclined rod 7.

In application, one pin is inserted into the upper pin hole 10, and then the rectangular connecting block 11 is slid into the rectangular groove 17, so that the rectangular connecting block 11 is separated from the rectangular groove 18. Then, another pin is inserted into the lower pin hole 10 to fix the rectangular connecting block 11, thereby realizing the disassembly or installation of the device. During installation, when the lower end of the sleeve 3 is close to the inclined rod 7, the pin is pulled out to release the rectangular connecting block 11, so that its lower end is inserted into the rectangular groove 18.

[0038] A rotating handle 6 is provided at the upper end of the sleeve 3, and the sleeve can be rotated by rotating the handle 6.

[0039] After the upper end of the support mechanism is fixed by the locking bolt 12, the rectangular connecting block 11 is temporarily fixed in the rectangular groove 17 by the pin. Then, the sleeve 3 is rotated by rotating the handle 6. The sleeve 3 moves downward and approaches the inclined rod 7. When the distance between them is small enough, the rectangular connecting block 11 is aligned with the rectangular groove 18 below by rotating the sleeve 3. Then, the pin is removed and the lower end of the rectangular connecting block 11 is slid into the rectangular groove 18 to connect the sleeve 3 and the inclined rod 7. Then, the sleeve 3 is rotated to rotate the inclined rod 7, thereby inserting the inclined rod 7 into the ground. When the lower end of the sleeve 3 abuts against the bottom surface of the circular groove 14, it can no longer be rotated. At this time, the support mechanism supports the pile 2 and the base plate 1.
