Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to a prestressed pipe pile supporting mechanism and a supporting method. Background Art

[0002] With the rapid development of urbanization, underground structures are developing in a deeper direction. The underground structures of some buildings have inconsistent numbers of underground garages. During the construction process, the low-span garage is usually constructed first. During the construction of the low-span garage, the high-span garage cannot be constructed independently. The construction of the high-span garage cannot begin until the construction of the low-span garage is completed and the outer wall of the low-span garage is backfilled. In addition, the traditional foundation pit support uses a combination of concrete cast-in-place piles and crown beams to form an overall support system.

[0003] According to the content disclosed in Chinese patent number CN214993771U, after the second connecting structure 6 is tightly embraced by the pile body 2, the second connecting structure 6 is welded to the connecting plate 4, and then the pile body 1 is lifted so that one end of the pile body 1 is installed on the first connecting structure 5, the pile body 1 is adjusted so that the axis of the pile body 1 and the pile body 2 coincide with each other, and the first connecting structure 5 is welded to the connecting plate 4, so as to achieve the effect of conveniently connecting pipe piles of different diameters.

[0004] However, although the above scheme uses the method of adjusting pile body 1 to make the axes of pile body 1 and pile body 2 coincide with each other and welding the first connecting structure 5 to the connecting plate 4 to achieve the effect of connecting pipe piles of different diameters, it ignores the protection and load-bearing aspects of the pipe pile support. Its overall load-bearing and safety performance are poor. Therefore, we propose a prestressed pipe pile support mechanism and support method. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a prestressed pipe pile support mechanism and support method. When the vehicle transmits gravity to the central position of the prestressed pipe pile, the central support block moves downward under pressure or the ground vibrates, and the airbag support block is compressed, the pressure is transmitted to the airbag through the second push rod, and the airbag transmits the pressure to the concrete on both sides through the compression hose. At the same time, when the second arc-shaped limit frame vibrates, the left and right sides decompose the vibration force, and use the first push rod to synchronously transmit it to the concrete to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a prestressed pipe pile support mechanism, comprising a side positioning frame, wherein the outer surface of the side positioning frame is connected to a connecting frame by bolts, and the two side positioning frames are connected by corresponding threaded rods and nuts to be assembled and fixed, so that the two can be easily disassembled and assembled. After the side positioning frame and the connecting frame are fixed, it is convenient for workers to place them on the reinforced concrete cushion layer, one end of the connecting frame is fixedly connected to the reinforced concrete cushion layer, and the number of side positioning frames is multiple, and the multiple groups of side positioning frames are arranged in a linear arrangement state with respect to the interior of the connecting frame;

[0007] The side positioning frames are connected by bolts to form multiple groups of corresponding threaded rods, and the bottom ends of the side positioning frames are plugged with detachable plug-in frames, and the outer surface of the detachable plug-in frames is provided with a threaded frame, and the outer surface of the detachable plug-in frames is connected to multiple groups of prestressed pipe pile leaf frames through the threaded frame. The interior of the prestressed pipe pile leaf frame is provided with a built-in thread, and the built-in thread and the threaded frame are arranged in a meshing state. The block-shaped prestressed pipe pile leaf frames can be meshed and connected and fixed with the threaded frame through the built-in thread. The prestressed pipe pile leaf frame is provided with a rotation groove at one end facing the side positioning frame, and the inner wall of the rotation groove is arranged in an arc-shaped state. When the threaded frame gradually rotates to the inside of the prestressed pipe pile leaf frame, the side positioning frame drives the fitting rod to slide synchronously along the arc groove of the rotating groove through rotation. One end of the rotating groove is fixedly connected with a blocking block, and the two ends of the side positioning frame are fixedly connected with fitting rods, and the fitting rod is fixedly connected with a fixed block toward one end of the rotating groove. The staff rotates and first uses the corresponding threaded rod to merge the two sets of side positioning frames, and inserts the steel pipe from the positioning socket into the installation hole inside the detachable socket frame, then fixes the positioning socket and the detachable socket frame, and at the same time, multiple sets of positioning sockets are placed in the connecting frame to complete the installation of the prestressed pipe pile head.

[0008] In a preferred embodiment, the engaging rod and the fixing block are located above the rotating groove, and the fixing block is arranged in a sliding state inside the rotating groove. A positioning hole is opened inside the side positioning frame, and a steel bar pipe is inserted into the interior of the positioning hole, and one end of the steel bar pipe passes through the positioning hole and is inserted into the interior.

[0009] In a preferred embodiment, a card hole is opened inside the prestressed pipe pile leaf frame, and a gap is set between each of the prestressed pipe pile leaf frames. One end of one group of prestressed pipe pile leaf frames is hinged with a second hinged rod through the card hole, and one end of the other group of prestressed pipe pile leaf frames is hinged with a first hinged rod. The first hinged rod and the second hinged rod are arranged in a hinged state. Since two suitable models need to be purchased for the installation of pipe piles of different diameters and pipe pile heads of different diameters, the prestressed pipe pile leaf frames are designed to be installed in a combined manner. Corresponding to pipe pile heads of different diameters, multiple groups of prestressed pipe pile leaf frames are initially in a separated state, and then the prestressed pipe pile leaf frames are pushed between each other, and the size of the gap between the two prestressed pipe pile leaf frames is adjusted by the first hinged rod and the second hinged rod, so that the inner wall of the prestressed pipe pile leaf frame fits into the detachable plug-in frame.

[0010] In a preferred embodiment, multiple groups of prestressed pipe pile leaf frames constitute prestressed pipe piles, and the inner walls of multiple groups of the prestressed pipe pile leaf frames are fixedly connected with rubber pull rods made of rubber material. As the spacing between the prestressed pipe pile leaf frames is adjusted, the rubber pull rods can be stretched and compressed as the prestressed pipe pile leaf frames move by utilizing the characteristics of the rubber material. The closer the prestressed pipe pile leaf frame is to the surface of the side positioning frame, the tighter the rubber pull rods are squeezed, making the surface of the prestressed pipe pile leaf frame more stable, making it easier to transfer the pressure outside the prestressed pipe pile leaf frame to both sides. The inside of the rubber pull rod is fixedly connected to an inner protective rod, and the two ends of the inner protective rod are fixedly connected to a compression hose.

[0011] In a preferred embodiment, the inner wall of the compression hose is provided with a pressure groove in a compressed state, and the interior of the pressure groove is an annular inner wall. Multiple groups of auxiliary springs are arranged on the annular inner wall of the pressure groove, and the multiple groups of auxiliary springs are arranged in an annular state with respect to the annular inner wall of the pressure groove. When the airbag transfers pressure to the compression hose, the auxiliary springs between the pressure grooves can buffer the pressure in all directions.

[0012] In a preferred embodiment, the surface of the inner protective rod is fixedly connected to a central support block, the bottom end of the central support block is fixedly connected to multiple sets of clip-on frames, a first arc-shaped limit frame is fixedly connected between each of the clip-on frames, and the top end of the first arc-shaped limit frame is fixedly connected to the bottom end of the central support block, and the end of the clip-on frame away from the first arc-shaped limit frame is hingedly connected to a first positioning rod.

[0013] In a preferred embodiment, the bottom end of the first positioning rod is fixedly connected to the second arc-shaped limit frame, the two sides of the second arc-shaped limit frame are fixedly connected to the supporting pushing rods, the bottom end of the first positioning rod is hinged to the second positioning rod, and the bottom end of the second positioning rod is hinged to the semicircular placement frame, and the semicircular placement frame is fixedly installed inside the inner protective rod.

[0014] In a preferred embodiment, the number of the semicircular mounting frames is two groups, and an airbag support block is fixedly connected between each pair of the semicircular mounting frames. A slide frame is fixedly connected inside the semicircular mounting frames, and two groups of spring telescopic rods are slidably connected inside the slide frame. A telescopic rod is fixedly connected between the two groups of spring telescopic rods, and the telescopic rod is located below the second arc-shaped limit frame.

[0015] In a preferred embodiment, the support pushing rod passes through one end of the semicircular mounting frame and is fixedly connected to a first push rod, both ends of the airbag support block are fixedly connected to a second push rod, the inside of the inner protective rod is fixedly connected to an airbag, the first push rod and the second push rod are fixedly installed at one end of the airbag, and the central support block and the semicircular mounting frame are fixedly connected. Since the prestressed pipe piles are used to bear weight in the later stage, the prestressed pipe piles mainly bear the pressure from above, and when the vehicle passes over the prestressed pipe piles, the bearing force at both ends of the vehicle depends on the side positioning frame and the connecting frame, which are close to the reinforced concrete cushion layer. The bearing force is easier to be transmitted to the concrete, and the stability is better.

[0016] A method for supporting prestressed pipe piles, comprising the following steps:

[0017] S1: First, use the corresponding threaded rods to merge the two sets of side positioning frames, insert the steel pipe from the positioning socket into the installation hole inside the detachable socket, then fix the positioning socket and the detachable socket, and at the same time, place multiple sets of positioning sockets in the connecting frame to complete the installation of the prestressed pipe pile head;

[0018] S2: Multiple groups of prestressed pipe pile leaf frames are initially in a separated state, and then the two prestressed pipe pile leaf frames are pushed against each other, and the size of the gap between the two prestressed pipe pile leaf frames is adjusted by the first hinged rod and the second hinged rod, so that the inner wall of the prestressed pipe pile leaf frame fits on the detachable plug-in frame, and the detachable plug-in frame rotates by engaging with the built-in thread through the threaded frame. When the side positioning frame rotates to a surface close to the prestressed pipe pile leaf frame, the side positioning frame slides into the rotating groove with the matching clamping rod and the fixing block, and at the same time the blocking block limits the fixing block, completing the overall installation of the prestressed pipe pile;

[0019] S3: Prestressed pipe piles mainly bear the pressure from above. When a vehicle passes over the prestressed pipe piles, the load-bearing force at both ends relies on the side positioning frames and connecting frames, which are close to the reinforced concrete cushion layer, to transmit the load-bearing force to the concrete.

[0020] S4: When the vehicle transmits gravity to the center position of the prestressed pipe pile, when the central support block moves downward under pressure or the ground vibrates, the second arc-shaped limit frame slides and squeezes the spring telescopic rod, and the spring telescopic rod drives the telescopic rod to be compressed, and the spring characteristics of the telescopic rod and the spring telescopic rod are used to buffer the vibration force. At the same time, the vibration force of the semicircular placement frame squeezes the airbag support block. When the airbag support block is compressed, the pressure is transmitted to the airbag through the second push rod. The airbag transmits the pressure to the concrete on both sides through the compression hose. At the same time, when the second arc-shaped limit frame vibrates, the left and right sides decompose the vibration force and use the first push rod to synchronously transmit it to the concrete, thereby completing the decomposition of the central force of the load-bearing object and then completing the support of the prestressed pipe pile.

[0021] The technical effects and advantages of the present invention are as follows:

[0022] When the vehicle transmits gravity to the center of the prestressed pipe pile, the central support block moves downward under pressure or the ground vibrates. When the airbag support block is compressed, the pressure is transmitted to the airbag through the second push rod. The airbag transmits the pressure to the concrete on both sides through the compression hose. At the same time, when the second arc-shaped limit frame vibrates, the left and right sides decompose the vibration force and transmit it to the concrete synchronously through the first push rod, thereby completing the decomposition of the central force of the load-bearing object and completing the support of the prestressed pipe pile.

[0023] The detachable plug-in bracket rotates by engaging with the built-in thread through the threaded bracket. When the side positioning bracket rotates to the surface close to the prestressed pipe pile leaf bracket, the side positioning bracket slides into the rotating groove with the matching clamping rod and the fixed block. At the same time, the blocking block limits the fixed block to prevent it from falling out, so that the prestressed pipe piles and the pile heads of the prestressed pipe pile leaf bracket are precisely connected, thereby facilitating the installation of pipe piles of different diameters and pile heads of different diameters, saving installation costs, and facilitating disassembly and installation between the two.

One end of the connecting frame 2 is fixedly connected to the reinforced concrete cushion layer, and the number of side positioning frames 3 is multiple groups, and the multiple groups of side positioning frames 3 are arranged in a linear arrangement state with respect to the interior of the connecting frame 2. The length in the reinforced concrete cushion layer is at least 200mm, and C30 micro-expansive concrete is used. The support plate is fixedly installed on the top of the multiple groups of prestressed pipe piles, and the support plate is used to bear the pressure from above, and the outer edge of the support plate and the inner wall of the pile hole of the prestressed pipe pile are provided with a spacing of less than or equal to 10mm;

[0036] The two side positioning frames 3 are connected with multiple groups of corresponding threaded rods 5 by bolts, and the bottom end of the side positioning frame 3 is plugged with a detachable plug-in frame 7, and the outer surface of the detachable plug-in frame 7 is provided with a threaded frame 8. The outer surface of the detachable plug-in frame 7 is connected to multiple groups of prestressed pipe pile leaf frames 1 through the threaded frame 8. The interior of the prestressed pipe pile leaf frame 1 is provided with a built-in thread 13, and the built-in thread 13 is engaged with the threaded frame 8. The block-shaped prestressed pipe pile leaf frame 1 can be engaged and fixed with the threaded frame 8 through the built-in thread 13. The prestressed pipe pile leaf frame 1 is provided with a rotation groove 10 at one end facing the side positioning frame 3, and the inner wall of the rotation groove 10 is arranged in an arc-shaped state. When the threaded frame 8 gradually rotates to the inside of the prestressed pipe pile leaf frame 1, the side positioning frame 3 drives the engaging rod 9 to slide synchronously along the arc groove of the rotation groove 10 through rotation. One end of the rotation groove 10 is fixedly connected to a blocking block 11, and both ends of the side positioning frame 3 are fixedly connected to a fitting rod 9, and the fitting rod 9 is fixedly connected to a fixing block 12 at one end facing the rotation groove 10. The fitting rod 9 and the fixing block 12 are located above the rotation groove 10, and the fixing block 12 is set in a sliding state inside the rotation groove 10. A positioning hole 4 is opened inside the side positioning frame 3, and a steel pipe is inserted into the interior of the positioning hole 4, and one end of the steel pipe passes through the positioning hole 4 and is inserted into the interior of the detachable plug-in frame 7. The staff rotates and first uses the corresponding threaded rod 5 to merge the two groups of side positioning frames 3, and inserts the steel pipe from the positioning hole 4 into the installation hole inside the detachable plug-in frame 7, then fixes the positioning hole 4 to the detachable plug-in frame 7, and at the same time, multiple groups of positioning holes 4 are placed in the connecting frame 2 to complete the installation of the prestressed pipe pile head.

[0037] Reference Figure 2-7, Example 2: The interior of the prestressed pipe pile leaf frame 1 is provided with a card hole 6, and a gap is provided between the two prestressed pipe pile leaf frames 1. One end of one group of prestressed pipe pile leaf frames 1 is hinged with a second hinged rod 15 through the card hole 6, and one end of the other group of prestressed pipe pile leaf frames 1 is hinged with a first hinged rod 14. The first hinged rod 14 and the second hinged rod 15 are arranged in a hinged state. Due to the installation of pipe piles of different diameters and pipe pile heads of different diameters, two suitable models need to be purchased. The prestressed pipe pile leaf frame 1 is designed to be installed in a combined manner. Corresponding to the heads of pipe piles of different diameters, multiple groups of prestressed pipe pile leaf frames 1 are initially in a separated state, and then the two prestressed pipe pile leaf frames 1 are pushed between each other. The size of the gap between the pipe pile leaf frame 1 is adjusted by the first hinge rod 14 and the second hinge rod 15, so that the inner wall of the prestressed pipe pile leaf frame 1 fits into the detachable plug-in frame 7, and the detachable plug-in frame 7 rotates by engaging with the built-in thread 13 through the threaded frame 8. When the side positioning frame 3 rotates to a surface close to the prestressed pipe pile leaf frame 1, the side positioning frame 3 slides into the rotating groove 10 with the matching clamping rod 9 and the fixed block 12. At the same time, the blocking block 11 limits the fixed block 12 to prevent it from falling out, so that the prestressed pipe pile and the pipe pile head of the prestressed pipe pile leaf frame 1 are precisely connected, thereby facilitating the installation of pipe piles of different diameters and pipe pile heads of different diameters, saving installation costs, and facilitating disassembly and installation between the two.

[0038] Reference Figure 2-6 , Example 3: Multiple groups of prestressed pipe pile leaf frames 1 form prestressed pipe piles, and the inner walls of the multiple groups of prestressed pipe pile leaf frames 1 are fixedly connected with rubber pull rods 17 made of rubber material. As the spacing between the prestressed pipe pile leaf frames 1 is adjusted, the rubber pull rods 17 can be stretched and compressed as the prestressed pipe pile leaf frames 1 move by utilizing the characteristics of the rubber material, and the closer the prestressed pipe pile leaf frame 1 is to the surface of the side positioning frame 3, the tighter the rubber pull rods 17 are squeezed, making the surface of the prestressed pipe pile leaf frame 1 more stable, and facilitating the transmission of the external pressure of the prestressed pipe pile leaf frame 1 to both sides, and the inside of the rubber pull rod 17 is fixedly connected with an inner protective rod 16, and the two ends of the inner protective rod 16 are fixedly connected with compression hoses 19. At the same time, a spacing of not less than 1000 mm is set between multiple prestressed pipe piles.

[0039] Reference Figure 4-9 Embodiment 4: A compression groove 21 is provided on the inner wall of the compression hose 19, and the inner wall of the pressure groove 21 is an annular inner wall. Multiple groups of auxiliary springs 20 are provided on the annular inner wall of the pressure groove 21, and the multiple groups of auxiliary springs 20 are arranged in an annular state with respect to the annular inner wall of the pressure groove 21. When the airbag 33 transmits pressure to the compression hose 19, the auxiliary springs 20 between the pressure grooves 21 can buffer the pressure in all directions.

[0040] The surface of the inner protective rod 16 is fixedly connected to a central support block 18, and the bottom end of the central support block 18 is fixedly connected to multiple groups of clamping frames 25. A first arc-shaped limiting frame 24 is fixedly connected between each of the clamping frames 25, and the top of the first arc-shaped limiting frame 24 is fixedly connected to the bottom end of the central support block 18. The end of the clamping frame 25 away from the first arc-shaped limiting frame 24 is hingedly connected to a first positioning rod 26, and the bottom end of the first positioning rod 26 is fixedly connected to a second arc-shaped limiting frame 28. Both sides of the second arc-shaped limiting frame 28 are fixedly connected to supporting pushing rods 29, and the bottom end of the first positioning rod 26 is hingedly connected to a second positioning rod 27. The bottom end of the second positioning rod 27 is hingedly connected to a semicircular placement frame 23, and the semicircular placement frame 23 is fixedly installed inside the inner protective rod 16;

[0041] There are two groups of semicircular mounting frames 23. An airbag support block 22 is fixedly connected between the two semicircular mounting frames 23. A chute frame 30 is fixedly connected inside the semicircular mounting frames 23. Two groups of spring telescopic rods 32 are slidably connected inside the chute frame 30. A telescopic rod 31 is fixedly connected between the two groups of spring telescopic rods 32. The telescopic rod 31 is located below the second arc-shaped limit frame 28.

[0042] The support push rod 29 passes through one end of the semicircular mounting frame 23 and is fixedly connected to the first push rod. The two ends of the airbag support block 22 are fixedly connected to the second push rod. The inside of the inner protective rod 16 is fixedly connected to the airbag 33. The first push rod and the second push rod are fixedly installed at one end of the airbag 33. The central support block 18 is fixedly connected to the semicircular mounting frame 23. Since the prestressed pipe piles are used for bearing weight in the later stage, a gap of not less than 1000mm is provided between multiple prestressed pipe piles. The prestressed pipe piles mainly bear the pressure from above. When the vehicle passes over the prestressed pipe piles, the bearing force at both ends depends on the side positioning frame 3 and the connecting frame 2, which are close to the reinforced concrete cushion layer. The bearing force is easier to transmit to the concrete, so the stability is better. The central part of the prestressed pipe pile is far away from the concrete, so the bearing capacity is poor. When the vehicle transmits gravity to the central position of the prestressed pipe pile, when the central support block 18 is subjected to pressure and moves downward to a certain extent or when the ground vibrates, due to the fixed tension of the first arc-shaped limit frame 24, the second The load-bearing state of the second positioning rod 27, the first positioning rod 26 and the semicircular mounting frame 23 is relatively stable. The volume of the second arc-shaped limit frame 28 is larger than that of the first arc-shaped limit frame 24, so the stable tension between the second arc-shaped limit frame 28 is larger. If the second arc-shaped limit frame 28 slides due to vibration, the second arc-shaped limit frame 28 slides and squeezes the spring telescopic rod 32, and the spring telescopic rod 32 drives the telescopic rod 31 to be in a compressed state, and the spring characteristics of the telescopic rod 31 and the spring telescopic rod 32 are used to buffer the vibration force. At the same time, the vibration force of the semicircular mounting frame 23 squeezes the airbag support block 22, and the airbag support block 22 is compressed, transmitting the pressure to the airbag 33 through the second push rod. The airbag 33 transmits the pressure to the concrete on both sides through the compression hose 19. At the same time, when the second arc-shaped limit frame 28 vibrates, the left and right sides decompose the vibration force and use the first push rod to transmit it to the concrete synchronously, thereby realizing the transmission of the external impact force of the vehicle to the concrete, reducing the load-bearing capacity of the pile pump body, and improving the stability of the pile.

[0043] A method for supporting prestressed pipe piles, comprising the following steps:

[0044] S1: First, use the corresponding threaded rod 5 to merge the two sets of side positioning frames 3, insert the steel pipe from the positioning socket 4 into the placement hole inside the detachable socket 7, then fix the positioning socket 4 and the detachable socket 7, and at the same time, place multiple sets of positioning sockets 4 in the connecting frame 2 to complete the installation of the prestressed pipe pile head;

[0045] S2: The multiple groups of prestressed pipe pile leaf frames 1 are initially in a separated state, and then the two prestressed pipe pile leaf frames 1 are pushed, and the size of the gap between the two prestressed pipe pile leaf frames 1 is adjusted by the first hinged rod 14 and the second hinged rod 15, so that the inner wall of the prestressed pipe pile leaf frame 1 is fitted on the detachable plug-in frame 7, and the detachable plug-in frame 7 is engaged and rotated with the built-in thread 13 through the threaded frame 8. When the side positioning frame 3 is rotated to a surface close to the prestressed pipe pile leaf frame 1, the side positioning frame 3 slides into the rotating groove 10 with the matching card rod 9 and the fixed block 12, and at the same time the blocking block 11 limits the fixed block 12, completing the overall installation of the prestressed pipe pile;

[0046] S3: The prestressed pipe piles mainly bear the pressure from above. When a vehicle passes over the prestressed pipe piles, the load-bearing force at both ends is transmitted to the concrete by the side positioning frame 3 and the connecting frame 2, which are close to the reinforced concrete cushion layer.

[0047] S4: When the vehicle transmits gravity to the central position of the prestressed pipe pile, when the central support block 18 moves downward under pressure or the ground vibrates, the second arc-shaped limit frame 28 slides and squeezes the spring telescopic rod 32, and the spring telescopic rod 32 drives the telescopic rod 31 to be compressed, and the spring characteristics of the telescopic rod 31 and the spring telescopic rod 32 are used to buffer the force of the vibration. At the same time, the vibration force of the semicircular mounting frame 23 squeezes the airbag support block 22. When the airbag support block 22 is compressed, the pressure is transmitted to the airbag 33 through the second push rod. The airbag 33 transmits the pressure to the concrete on both sides through the compression hose 19. At the same time, when the second arc-shaped limit frame 28 vibrates, the left and right sides decompose the vibration force and use the first push rod to synchronously transmit it to the concrete, thereby completing the decomposition of the central force of the load-bearing object and then completing the support of the prestressed pipe pile.
