Description

Technical Field

[0001] This invention relates to a device and method for breaking pile heads of Yunba rail transit piles, and more particularly to a device and method for breaking pile heads of Yunba rail transit piles based on heating and freeze-thaw cycles. Background Technology

[0002] When pouring cast-in-place piles, the top elevation of the pile should be 0.8-1.0m higher than the designed top elevation to ensure the strength of the pile head concrete. However, the portion of the pile head that exceeds the designed top elevation must be removed during subsequent construction processes. This removal of the pile head concrete is called "pile head breaking." Therefore, pile head breaking devices are an important construction tool. Currently, there is no pile head breaking device based on heating and freeze-thaw cycles for the Yunba rail piles. Pile head breaking tools are mainly divided into manual and mechanical methods. Mechanical pile head breaking is technically called a pile breaker or pile cutter, and its speed is many times faster than manual breaking. If the construction period is tight, mechanical breaking is recommended. Mechanical breaking generally applies vibration force to the pile head, causing it to split and break. Because it requires vibration force, it generates noise and dust pollution in the construction environment.

[0003] This invention, through its technical feature of rapidly pulverizing concrete by placing the pile head in a cyclical heat exchange environment, effectively explores and studies the technical problem of mechanical demolition, which generally involves applying vibration force to the pile head.

[0048] This invention designs a method for using a pile head breaking device for Yunba rail transit based on heating and freeze-thaw cycles. The steps are as follows: the shell allows the upper and lower parts of the pile head to be in heating and freeze-thaw states respectively, and the cover allows the shell to be sealed, thus enabling the pile head to be in a cyclical heat exchange environment for rapid concrete pulverization.

[0049] The technical effects of the above technical solutions are: highlighting the technical feature of rapidly pulverizing concrete by placing the broken pile head in a cyclical heat exchange environment, and introducing a method for using the Yunba rail pile head breaking device based on heating and freeze-thaw cycles in the technical field.

[0050] The present invention is designed with the following steps: When performing pile head breaking treatment on the Yunba rail pile, a line is drawn at the root of the pile head on the Yunba rail pile. A drill rod is used to drill a hole at the root of the pile head, obtaining an isolation hole at the root of the pile head, ensuring that the isolation hole avoids the reinforcing bar. An asbestos rod is installed in the isolation hole. A drill rod is used to create grooves on the peripheral sides and upper end face of the pile head. A slit is created on the upper end face of the pile head along the radial line using a water flow cutting method. The sealing component located on platform II is placed on the root of the pile head, so that the clamping part is in a closed state. The retaining body of the tray part is clamped on the root of the pile head, thereby placing the sealing component located on platform II. Installed at the root of the pile head, connect the lifting hook to the lifting hole body, and lift the box shell using lifting machinery. Fit Box I, Cylinder, Box II, Platform I, and Platform II onto the pile head, aligning Box I with the upper part of the pile head and Cylinder and Box II with the lower part of the pile head. Place the lower end of the support beam on the foundation of the Yunba rail pile column, and connect the upper end of the support beam to the receiving hole body using bolts, thus installing the box shell onto the pile head. Place the sealing assembly located on Platform I onto the middle part of the pile head, ensuring the clamping part is closed. Clamp the tray body onto the middle part of the pile head, thus installing the sealing assembly located on Platform I onto the middle part of the pile head. Finally, the screw part located on Platform I... Rotate the middle horizontal section of the tray to push the plate downwards, causing the ring part to act on platform I. This causes the screw part on platform II to rotate on the middle horizontal section of the tray, pushing the plate upwards and causing the ring part to act on platform II. Place the box cover on the upper end face of box I, rotating the bolts on the peripheral side face of the box cover. This causes the inner end face of the bolts on the peripheral side face of the box cover to act on box I, thus installing the box cover on box I. Connect the outer end of the upper tube shell to the heating medium source output port, and connect the outer end of the lower tube shell to the freezing medium source output port, opening the valves to inject the heating medium into box I. This heats the upper part of the broken pile head and injects the freezing medium into the box. In section II, the lower part of the pile-breaking head is cooled. When the outer end of the upper shell is connected to the output port of the cooling medium source, and the outer end of the lower shell is connected to the output port of the heating medium source, the valves are open, and the cooling medium is injected into section I to cool the upper part of the pile-breaking head. The heating medium is injected into section II to heat the lower part of the pile-breaking head. A safety valve limits the pressure of the medium in sections I and II. Temperature and pressure indicators are monitored online for both sections, ensuring the vibrator is in operation with its vibrating head extended. The vibrator overcomes the elastic energy stored by the spring.The rod needle moves inward on box sections I and II, impacting the pile head. The vibrator's head is in a retracted state. Under the elastic energy storage of the spring, the rod needle moves outward on box sections I and II, returning to its initial state. Through heating and freeze-thaw cycles on the upper and lower parts of the pile head, the concrete of the pile head is brought to a failure state. After the concrete of the pile head has reached a failure state, the sealing assembly located on platform I is... The components are disassembled from the middle part of the pile head. The sealing assembly located on platform I is removed from the pile head. The support beam is removed from pole I. The lifting hook is connected to the lifting hole. The box shell is lifted using lifting machinery. Box I, cylinder, box II, platform I, and platform II are removed from the pile head. The upper and lower parts of the pile head are heated with a flame. The upper and lower parts of the pile head are then hammered to remove the concrete from the pile head.

[0051] The technical effect of the above solution is that it enables the failure operation of the water flow cutting block of the broken pile head concrete under high and low temperature environments.

[0052] This invention designs a water jet cutting method using a cutting water jet containing garnet abrasive and supercooled water at 0-4°C.

[0053] The technical effect of the above solution is that it enables low-temperature water flow cutting of the concrete at the pile head.

[0054] The present invention is designed with water vapor as the heating medium and liquid nitrogen as the freezing medium.

[0055] The technical effect of the above solution is that it enables the concrete of the broken pile head to be heated by steam and cooled by liquid nitrogen.

[0056] The present invention is designed such that the heating treatment is held at a temperature of 90-100°C for 1.5-2 hours and the cooling treatment is held at a temperature of -10-50°C for 1.5-2 hours.

[0057] The technical effect of the above solution is that it enables high and low temperature environmental cyclic treatment of the concrete at the broken pile head.

[0058] In this technical solution, the housing and the cover are the basic components and essential technical features of the invention. The upper shell, lower shell, valve, safety valve, temperature indicator, pressure indicator, sealing assembly, rod needle, spring, vibrator, support frame, isolation hole, asbestos rod, reinforcing bar, groove, and slit are functional components that enable other technical effects of the invention. The design of the following technical features—box I, cylinder, box II, platform I, platform II, tray, clamp, screw, plate, ring, rod I, rod II, lifting hole, and receiving hole—complies with the Patent Law and its implementing regulations.

[0059] In this technical solution, the rapid pulverization of concrete in a circulating heat exchange environment for the broken pile head is achieved by the box shell.

[0060] In this technical solution, the key technical feature is the box shell and box cover that allow the pile head to undergo rapid concrete pulverization in a cyclic hot and cold exchange environment. In the technical field of pile head breaking device and usage method based on heating and freeze-thaw cycles for Yunba rail piles, this solution is novel, inventive, and practical.

[0103] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0104] A method for using a pile head breaking device for Yunba rail transit based on heating and freeze-thaw cycles includes the following steps: When breaking the pile head of a Yunba rail transit pile, a line is drawn at the root of the pile head. A drill rod is used to drill a hole along the drawn line at the root of the pile head, creating an isolation hole 30 at the root of the pile head. The isolation hole 30 avoids the reinforcing bar 50. An asbestos rod 40 is installed in the isolation hole 30. A drill rod is used to create grooves 20 on the peripheral sides and upper end face of the pile head. Finally, a slit 10 is created on the upper end face of the pile head along its radial line using a water jet cutting method.

[0105] Place the sealing assembly 8 located on the platform II15 onto the root of the broken pile head, so that the clamping part 82 is in the closed state, and clamp the separating body of the tray part 81 onto the root of the broken pile head, thereby installing the sealing assembly 8 located on the platform II15 onto the root of the broken pile head.

[0106] Connect the lifting hook to the lifting hole 933, and lift the box shell 1 using lifting machinery. Fit box section I 11, cylinder section 12, box section II 13, platform section I 14, and platform section II 15 onto the pile breaking head, aligning box section I 11 with the upper part of the pile breaking head, and aligning cylinder section 12 and box section II 13 with the lower part of the pile breaking head. Place the lower end of the support beam onto the foundation of the Yunba rail pile, and connect the upper end of the support beam to the receiving hole 934 using bolts, thus installing the box shell 1 onto the pile breaking head.

[0107] Place the sealing assembly 8 on platform I14 onto the middle part of the pile head, so that the clamping part 82 is in the closed state. Clamp the separating body of tray 81 onto the middle part of the pile head, thereby installing the sealing assembly 8 on platform I14 onto the middle part of the pile head. Rotate the screw part 83 on platform I14 on the middle horizontal part of tray 81, pushing the plate part 84 downward, so that the ring part 85 acts on platform I14. Rotate the screw part 83 on platform II15 on the middle horizontal part of tray 81, pushing the plate part 84 upward, so that the ring part 85 acts on platform II15. Place the box cover 2 onto the upper end face of box I11. Rotate the bolts on the peripheral side face of box cover 2, so that the inner end face of the bolts on the peripheral side face of box cover 2 acts on box I11, thereby installing box cover 2 onto box I11.

[0108] When the outer end of the upper shell 3 is connected to the output port of the heating medium source, and the outer end of the lower shell 4 is connected to the output port of the freezing medium source, with valve 90 in the open state, the heating medium is injected into tank section I11 to heat the upper part of the broken pile head, and the freezing medium is injected into tank section II13 to cool the lower part of the broken pile head. When the outer end of the upper shell 3 is connected to the output port of the freezing medium source, and the outer end of the lower shell 4 is connected to the output port of the heating medium source, with valve 90 in the open state, the freezing medium is injected into tank section I11 to cool the upper part of the broken pile head, and the heating medium is injected into tank section II13 to heat the lower part of the broken pile head.

[0109] Safety valve 5 limits the pressure of the medium in tank I11 and tank II13. Temperature indicator 6 monitors the temperature values ​​in tank I11 and tank II13 online, and pressure indicator 7 monitors the pressure values ​​in tank I11 and tank II13 online.

[0110] When the vibrator 92 is in working condition, with its vibrating head extended, the vibrator 92 overcomes the elastic energy stored in the spring 91, causing the rod needle 9 to move inward on the box section I 11 and box section II 13, impacting the pile head. When the vibrator head of the vibrator 92 is in retracted condition, under the elastic energy stored in the spring 91, the rod needle 9 moves outward on the box section I 11 and box section II 13, returning to its initial state.

[0111] By subjecting the upper and lower parts of the broken pile head to heating and freeze-thaw cycles, the concrete of the broken pile head is brought to a state of failure. After the concrete of the broken pile head is brought to a state of failure, the sealing component 8 located on platform I14 is removed from the middle part of the broken pile head, and the sealing component 8 located on platform I14 is removed from the broken pile head. The support beam is removed from pole I931, the lifting hook is connected to the lifting hole 933, and the box shell 1 is lifted by the lifting machinery. Box I11, cylinder 12, box II13, platform I14 and platform II15 are removed from the broken pile head. The upper and lower parts of the broken pile head are flame-heated and hammered to remove the concrete from the broken pile head.

[0112] In this embodiment, water jet cutting uses a cutting water jet containing garnet abrasive and supercooled water at 0-4°C.

[0113] In this embodiment, the heating medium is set to water vapor and the freezing medium is set to liquid nitrogen.

[0114] In this embodiment, the heating treatment is set to be held at a temperature of 90-100°C for 1.5-2 hours and the cooling treatment is set to be held at a temperature of -10-50°C for 1.5-2 hours.

[0115] In verifying this invention, the inventors abandoned the existing technical feature of applying vibration force to the pile head in mechanical demolition. Instead, they first proposed a technical feature that rapidly pulverizes the concrete in a cyclical heat exchange environment at the pile head. This resulted in the first unexpected technical effect: pulverizing the concrete at the pile head without external crushing force, thus improving the stability of the Yunba rail piles. The second unexpected technical effect: regularly distributed grooves at the ends of the pile head increased the connection strength with the pier. The third unexpected technical effect: high and low temperature environmental treatment of the upper and lower parts of the pile head caused the stresses generated at the upper and lower parts to converge, improving the concrete splitting performance of the pile head. The fourth unexpected technical effect: achieving the effect of cutting... The joint 10 increases the distribution area of ​​the heating and freezing media, improving the heating and freeze-thaw effects of the concrete water-cutting block at the pile head, resulting in the fifth unexpected technical effect: the groove 20 improves the uniformity of the distribution of the heating and freezing media, increasing the heating and freeze-thaw efficiency of the concrete water-cutting block at the pile head, resulting in the sixth unexpected technical effect: impacting the concrete water-cutting block accelerates the splitting of the concrete at the pile head in the heat exchange environment, resulting in the seventh unexpected technical effect: ensuring that the temperature and pressure values ​​of the heating and freezing media in the shell 1 are within safe ranges, improving the safety performance of the pile head, resulting in the eighth unexpected technical effect: the support frame 93 facilitates the external connection of the shell 1 to the shell, making it easier to hoist and support the shell 1.

[0116] In a second embodiment of the present invention, the box shell 1 and the box cover 2 are connected to each other in a manner that allows the broken pile head to be subjected to rapid pulverization of concrete in a cyclic hot and cold exchange environment.

[0117] In this embodiment, the casing 1 and the cover 2 are connected to each other in such a way that the upper and lower parts of the broken pile head are in a heated and freeze-thawed state respectively.

[0124] In this embodiment, a seventh accessory device is also included and disposed between the housing 1 and the sixth accessory device. The seventh accessory device is configured to include a rod needle 9, a spring 91 and a vibrator 92.

[0125] The second embodiment of the present invention is based on the first embodiment.

[0126] In the second embodiment of the present invention, the steps are as follows: the shell 1 enables the upper and lower parts of the broken pile head to be in a heated and freeze-thawed state respectively, and the cover 2 enables the shell 1 to be sealed, thereby enabling the broken pile head to be in a circulating hot and cold exchange environment for rapid concrete pulverization.
