Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile foundation grouting technology, specifically a device for controlling over-grouting of the pile head in bored piles. Background Technology
[0002] Cast-in-place piles are piles made by forming pile holes in the foundation through mechanical drilling, steel pipe soil displacement, or manual excavation on the engineering site, and then placing a steel cage and pouring concrete into the holes. During the pile foundation pouring process, control devices are often used to detect the height of the concrete pouring.
[0003] The existing utility model patent with authorization announcement number CN220352825U discloses a device for controlling the over-pouring height of cast-in-place pile heads. Using this technical solution, the distance can be directly measured to see if the over-pouring height meets the expected standard, making the device very simple, easy to assemble and disassemble, and cost-effective. However, in the use of this device, workers need to rely on experience to pour concrete to a certain height and then check it. However, because the device is not convenient for real-time detection of the concrete height during pouring, it is easy for workers to exceed the required height before measurement due to insufficient experience, resulting in concrete waste and reducing the practicality of the device.
[0004] Therefore, those skilled in the art have provided a device for controlling over-grouting of bored pile heads to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a drilled pile head over-grouting control device to solve the problem that the over-grouting control device mentioned in the background art is not convenient for real-time detection of concrete height.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A device for controlling over-grouting at the head of a bored pile includes a pole with a detection mechanism provided on the outer surface of the pole.
[0008] The detection mechanism includes a connecting rod that is snapped into the inside of a vertical pole. A float plate is slidably connected to the outer surface of the vertical pole. Two sets of floats are fixedly installed on the bottom surface of the float plate. A connecting tube is sleeved on the outer surface of the connecting rod. A connecting plate is fixedly installed on the outer surface of the connecting tube. A pressure sensor is fixedly installed on the bottom surface of the connecting plate. A controller, a buzzer, and a warning light are fixedly installed on the upper surface of the connecting plate. A rubber sleeve is fixedly installed on the inner wall of the connecting tube. Two electric push rods are fixedly installed on both ends of the two electric push rods. Two sets of connecting springs are fixedly installed on the side of the two expansion plates that are close to each other.
[0009] As a further embodiment of this utility model: an installation plate is fixedly installed on the outer surface of the pole, and two sets of fixing cones are fixedly installed on the inner wall of the installation plate, with the bottom end of each fixing cone penetrating the installation plate and extending to the bottom of the installation plate.
[0010] As a further improvement of this utility model: the internal thread of the connecting rod is connected to a fixing bolt, and the end of the fixing bolt near the connecting rod passes through the connecting rod and extends into the interior of the upright.
[0011] As a further improvement of this utility model: each of the connecting springs is fitted with a telescopic rod inside, and the two ends of each telescopic rod are respectively fixedly connected to the side of the two expansion plates that are close to each other.
[0012] As a further improvement of this utility model: a storage battery is fixedly installed on the upper surface of the connecting plate, and the storage battery is electrically connected to the pressure sensor, controller, buzzer, warning light and electric push rod respectively through wires.
[0013] As a further embodiment of this utility model: a protective shell is fixedly installed on the upper surface of the connecting plate, and a protective cover is movably hinged to the upper surface of the protective shell.
[0014] As a further embodiment of this utility model: a locking block is fixedly installed on the left side of the protective cover, and a locking frame is fixedly installed on the left side of the protective shell, with the locking block snapped into the inside of the locking frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention features a vertical pole and a connecting rod, allowing workers to insert the connecting rod into the vertical pole. This facilitates adjustment of the device's height according to the required over-pouring height, increasing its practicality. The device includes a float, a float ball, a connecting pipe, a connecting plate, a pressure sensor, a controller, a buzzer, and a warning light. The buoyancy of the float and float ball causes the float to rise with the concrete. When the float contacts the pressure sensor, the controller activates the buzzer and warning light to alert the worker that the concrete has reached the designated height. This achieves real-time detection of over-pouring height, eliminating the need for workers to rely on experience to judge the height and reducing concrete waste. The device also includes a rubber sleeve, an electric push rod, an expansion plate, and a connecting spring. The electric push rod, combined with the expansion plate, causes the rubber sleeve to expand into the connecting pipe, fixing the connecting pipe to the connecting rod. This allows workers to easily adjust the pressure sensor height according to the over-pouring height, making the device suitable for over-pouring concrete at different heights.

[0022] Please see Figure 1-4An over-grouting control device for bored pile heads includes a pole 1. An installation plate 3 is fixedly installed on the outer surface of the pole 1. Two sets of fixing cones 4 are fixedly installed on the inner wall of the installation plate 3. The bottom end of each fixing cone 4 penetrates the installation plate 3 and extends to the bottom of the installation plate 3. The installation of the installation plate 3 and the fixing cones 4 makes it convenient for workers to fix the pole 1 to the inner bottom wall of the pile foundation pit, thereby minimizing the phenomenon of the pole 1 moving on its own and ensuring the stability of the pole 1.
[0023] The outer surface of the upright 1 is provided with a detection mechanism 2; the detection mechanism 2 includes a connecting rod 201, which is snapped into the inside of the upright 1. There are multiple connecting rods 201, so that workers can increase or decrease the number of connecting rods 201 according to the overfilling height. The internal thread of the connecting rod 201 is connected with a fixing bolt 5. The end of the fixing bolt 5 near the connecting rod 201 passes through the connecting rod 201 and extends into the inside of the upright 1. The installation of the fixing bolt 5 serves to fix the connecting rod 201 to the upright 1, thereby facilitating the splicing of the connecting rod 201.
[0024] A float plate 202 is slidably connected to the outer surface of the upright 1. Two sets of float balls 203 are fixedly installed on the bottom surface of the float plate 202. A connecting tube 204 is sleeved on the outer surface of the connecting rod 201. A connecting plate 205 is fixedly installed on the outer surface of the connecting tube 204. A protective shell 8 is fixedly installed on the upper surface of the connecting plate 205. A protective cover 9 is movably hinged to the upper surface of the protective shell 8. The installation of the protective shell 8 and the protective cover 9 plays a role in protecting the electronic components inside the protective shell 8, thereby minimizing the damage to the electronic components inside the protective shell 8 caused by external objects, and thus increasing the service life of the electronic components inside the protective shell 8.
[0025] A pressure sensor 206 is fixedly installed on the bottom surface of the connecting plate 205. A controller 207, a buzzer 208, and a warning light 209 are fixedly installed on the upper surface of the connecting plate 205. A rubber sleeve 210 is fixedly installed on the inner wall of the connecting pipe 204. The rubber sleeve 210 has good extensibility. A locking block 10 is fixedly installed on the left side of the protective cover 9. A locking frame 11 is fixedly installed on the left side of the protective shell 8. The locking block 10 is snapped into the inside of the locking frame 11. The installation of the locking block 10 and the locking frame 11 serves to lock the protective cover 9 onto the protective shell 8, thereby minimizing the possibility of the protective cover 9 opening on its own and ensuring the stability of the protective cover 9.
[0026] Two electric push rods 211 are fixedly installed on the inner wall of the connecting pipe 204. Two expansion plates 212 are fixedly installed at both ends of the two electric push rods 211. The extension and retraction directions of the two electric push rods 211 are opposite. A storage battery 7 is fixedly installed on the upper surface of the connecting plate 205. The storage battery 7 is electrically connected to the pressure sensor 206, the controller 207, the buzzer 208, the warning light 209 and the electric push rods 211 through wires. The installation of the storage battery 7 can provide power to the electrical equipment of the device, so that the device is not limited by the length of the wire, thereby increasing the practicality of the device.
[0027] Two sets of connecting springs 213 are fixedly installed on the side of the two expansion plates 212 that are close to each other. Each connecting spring 213 has a telescopic rod 6 inside. The two ends of each telescopic rod 6 are fixedly connected to the side of the two expansion plates 212 that are close to each other. The installation of the telescopic rod 6 plays a role in restricting the movement trajectory of the expansion plate 212, thereby avoiding the phenomenon of the expansion plate 212 deviating from the movement trajectory when moving, and thus ensuring the stability of the movement of the expansion plate 212.
[0028] The working principle of this utility model is as follows: In use, the worker first assembles the connecting rod 201 and the upright 1 according to the concrete over-pouring height. Then, the fixed cone 4 is inserted into the inner bottom wall of the pile foundation pit. Next, the worker places the floating plate 202 and the connecting pipe 204 onto the outer surface of the upright 1. Then, the worker opens the electric push rod 211, using the power provided by the electric push rod 211 in conjunction with the connecting spring 213 to move the two expansion plates 212 towards one side, thereby causing the expansion plates 212 to expand the rubber sleeve 210 into the connecting pipe 204, thus allowing the rubber sleeve 210 to connect with the connecting rod 201. The outer surface of the connecting pipe 204 is in contact with the connecting rod 201, thereby fixing the connecting pipe 204 to the connecting rod 201. This allows the worker to adjust the height of the pressure sensor 206 according to the overfilling height. Then, the worker fills the pile foundation pit with concrete, causing the floating plate 202 to rise with the height of the concrete. When the concrete height reaches the specified overfilling height, the floating plate 202 contacts the pressure sensor 206, causing the pressure sensor 206 to send a signal to the controller 207. This causes the controller 207 to control the buzzer 208 to sound and the warning light 209 to illuminate, thereby reminding the worker that the overfilling height has been reached and reducing concrete waste.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
