Description

Technical Field

[0001] This application relates to the field of pile foundation construction, and in particular to a pile foundation construction platform and a pile foundation construction method. Background Technology

[0002] A pile foundation consists of piles and pile caps. Pile construction methods are divided into two main categories: precast piles and cast-in-place piles. The selection of a pile driving method depends not only on the engineering geological conditions but also on the type, cross-section, length, site environment, and design requirements of the piles.

[0003] A pile foundation construction platform is a platform-type building set up around the pile foundation during the pile foundation construction process. Workers can position and control the pile foundation on the pile foundation construction platform to improve the convenience of the pile foundation construction process.

[0004] Currently, most pile foundation construction platforms are built using steel bars and steel plates, and the steel plates are surrounded by protective netting to complete the construction of the pile foundation construction platform. However, if the steel bars are slightly tilted during the construction process, the overall safety and stability of the platform will be affected, so improvements are needed. Summary of the Invention

[0005] In order to improve the related technology, this application provides a pile foundation construction platform and a pile foundation construction method.

[0006] The technical solution for the pile foundation construction platform and pile foundation construction method provided in this application is as follows:

[0007] A pile foundation construction platform includes a platform base, wherein a plurality of platform bases are provided, and an abutment device is provided between adjacent platform bases. The abutment device includes an abutment block, an abutment rod, and an abutment cylinder. The abutment cylinder is disposed between a pair of platform bases and is a bidirectional cylinder. The abutment rod is disposed at the output end of the abutment cylinder, and the abutment block is disposed at the end of the abutment rod away from the abutment cylinder. The abutment block is fitted against the side wall of the platform base.

[0008] By adopting the above technical solution, when the pile foundation construction platform of this application is used, the platform base is placed first, and then the abutment cylinder is set between a pair of platforms. After the platform base is set, the abutment cylinder is activated, so that the abutment cylinder drives a pair of abutment rods to move the abutment block toward the platform base. If the abutment block is completely in contact with the platform base, the platform base is placed vertically, thereby completing the construction of the pile foundation construction platform based on the platform base. Compared with the structure using steel reinforcement, the pile foundation construction platform of this application reduces the possibility of low platform safety and stability caused by the overall tilt of the platform during the construction process.

[0009] Optionally, the platform base is provided with a platform body on its top. The platform body has a connecting hole on its side wall near the platform base. The platform base is adapted to be inserted into the connecting hole. A horizontal detection device for detecting the platform body is provided in the connecting hole.

[0010] By adopting the above technical solution, when the pile foundation construction platform in this application is erected, the platform base is placed vertically through the structure of the abutting cylinder and the abutting block. The platform body is then placed on top of the platform base by lifting, and the top of the platform base is inserted into the connecting hole. Since the top of the platform base is adapted to the connecting hole, the platform body has high stability when installed on the platform base.

[0011] Optionally, the connecting hole is a square hole, and the horizontal detection device includes a pressure sensor and a buzzer. Four pressure sensors are provided and are located at the four inner corners of the connecting hole. The buzzer is electrically connected to the four pressure sensors and is triggered by the four pressure sensors.

[0012] By adopting the above technical solution, when the pile foundation construction platform in this application is being built, and the platform body is installed on top of the platform base, the structure that adapts to the top of the platform base through the connecting holes will trigger a buzzer when the platform base is inserted into the connecting holes. This improves the stability of the platform body installed on the platform base.

[0013] Optionally, a connecting groove is provided on the inner sidewall of the connecting hole, a pushing cylinder is provided at the bottom of the connecting groove, a connecting block is provided at the output end of the pushing cylinder, and a connecting groove for inserting the connecting block is provided on the sidewall of the platform base, and the connecting groove and the connecting block are adapted to each other.

[0014] By adopting the above technical solution, when the platform body is connected to the platform base, the push cylinder can be controlled to move the connecting block toward the platform base. The connecting block can be inserted into the connecting groove to fix the platform body and the platform base, thereby improving the stability of the connection between the platform base and the platform body and making the platform base and the platform body easier to install.

[0015] Optionally, a trigger groove is formed on the inner bottom wall of the connecting hole, and a trigger electromagnet is provided on the inner bottom wall of the trigger groove. The trigger electromagnet is electrically connected to the four pressure sensors. A connecting magnet is provided on the top of the platform base. The connecting magnet is magnetically attracted to the trigger electromagnet. A connector device is provided on the top of the platform base. The connecting magnet is disposed on the connector device. The connector device is used to control the push cylinder.

[0016] By adopting the above technical solution, when the platform body is set on the platform base and the platform body is set stably, that is, when all four pressure sensors are triggered, the trigger electromagnet is energized and attracts the connecting magnet, so that the connector device is connected, thereby triggering the push cylinder to push the connecting block and push the connecting block into the connecting groove, thereby completing the installation of the platform motherboard. By controlling the trigger electromagnet through the four pressure sensors, the stability of the connection between the platform body and the platform base is further increased when the connecting block is inserted into the connecting groove.

[0017] Optionally, the connector device includes a shift plate, a shift spring, a first trigger connector, and a second trigger connector. The shift spring is disposed on the top of the platform base, the shift plate is disposed at the end of the shift spring away from the platform base, the connecting magnet is embedded in the shift plate, the first trigger connector is disposed on the side wall of the shift plate near the trigger electromagnet, and the second trigger connector is disposed on the inner bottom wall of the trigger slot. When the trigger electromagnet is attracted to the connecting magnet, the first trigger connector and the second trigger connector are connected.

[0018] By adopting the above technical solution, when all four pressure sensors are triggered, the trigger electromagnet is energized, and the trigger electromagnet attracts the connecting magnet. The connecting magnet is embedded in the shift plate, and the shift plate moves towards the trigger electromagnet. When the shift plate moves to the point where the first trigger connector and the second trigger connector abut, the first trigger connector and the second trigger connector are connected to control the push cylinder, so that the push cylinder pushes the connecting block into the connecting groove, thereby improving the stability of the connection between the platform base and the platform body.

[0019] Optionally, the top of the platform body is provided with a mounting hole for inserting the platform base, and the mounting hole is adapted to fit the platform base.

[0020] By adopting the above technical solution, operators can stack the platform bases by inserting them into the installation holes. When the pile foundation is high, multiple layers of the platform can be added by stacking the platform bases and the platform body, thereby increasing the convenience of workers during construction.

[0021] Optionally, a connecting piece is provided on the side wall of the platform base, and a connecting hole is provided through the connecting piece in the vertical direction. A fixing hole is provided on the top of the platform body, and a fixing rod is inserted into both the fixing hole and the connecting hole. One end of the fixing rod passes through the fixing hole and is threadedly connected to the fixing hole.

[0022] By adopting the above technical solution, the structure of the connecting piece, connecting hole, and fixing hole allows the connecting piece to be fixed to the platform body by passing the fixing rod through the connecting hole and threading it into the fixing hole when another platform base is inserted into the mounting hole. This completes the fixation of the platform base and the platform body, improving the stability of the connection between the platform base and the platform body.

[0023] Optionally, the connecting piece and the platform base can be detachably connected.

[0024] By adopting the above technical solution, the structure in which the connecting piece is detachably connected to the platform body allows the connecting piece to be removed when there is no need to raise the platform body, so that the top of the platform body is relatively flat, thus improving the safety during construction.

[0025] Optionally, a pile foundation construction method includes:

[0026] S1. Determine the hole position and use the crosshair method to check the hole position after placing the center stake.

[0027] S2, Install a steel casing, align the axis of the steel casing with the axis of the hole, and weld the steel casing in place;

[0028] S3, punching, uses a combination of low-hammer dense impact and high-hammer hammer impact to impact the center pile;

[0029] S4. Clean the hole and build steel reinforcement support, remove the mud from the hole, and place the steel cage in the hole before completing the pouring.

[0030] By adopting the above technical solution, the center pile is first placed, and the hole position is determined by the crosshair method, which makes the center pile setting more accurate. Then, a steel casing is built into the pre-drilled hole, and the steel casing is welded and installed based on the height of the center pile. After installation, the center pile is installed by hammering. After installation, the hole is cleaned and the concrete is poured. The pile foundation formed by the above method has high stability.

[0031] In summary, this application includes at least one of the following beneficial effects:

[0032] 1. The structure of the abutting cylinder and abutting block is adopted. When the pile foundation construction platform of this application is used, the platform base is placed first. The abutting cylinder is set between a pair of platforms. After the platform base is set, the abutting cylinder is activated, which drives a pair of abutting rods to move the abutting block toward the platform base. If the abutting block is completely in contact with the platform base, the platform base is placed vertically. Thus, the pile foundation construction platform is built based on the platform base. Compared with the structure of steel reinforcement, the pile foundation construction platform of this application reduces the possibility of low platform safety and stability caused by the overall tilt of the platform during the construction process.

[0033] 2. The structure of connecting holes and level detection device is adopted. During the construction of the pile foundation construction platform in this application, the platform base is placed vertically by means of the structure of the abutting cylinder and the abutting block. The platform body is then set on the top of the platform base by the lifting method, and the top of the platform base is inserted into the connecting hole. Since the top of the platform base is adapted to the connecting hole, the stability of the platform body is high when it is installed on the platform base.

[0034] 3. A pressure sensor structure is adopted. When all four pressure sensors are triggered, the trigger electromagnet is energized, which attracts the connecting magnet. The connecting magnet is embedded in the shift plate, and the shift plate moves towards the trigger electromagnet. When the shift plate moves to the point where the first trigger connector and the second trigger connector abut, the first trigger connector and the second trigger connector are connected to control the push cylinder. This causes the push cylinder to push the connecting block into the connecting groove, thereby improving the stability of the connection between the platform base and the platform body.

[0041] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0042] This application discloses a pile foundation construction platform and a pile foundation construction method. (Refer to...) Figure 1 A pile foundation construction platform includes a platform base 1 and a platform body 14. The platform body 14 is fixed on the ground, and the platform base 1 is set on the platform body 14. The platform base 1 has a cuboid structure and a square cross-section. The platform base 1 is set around the device, and four platform bases are set around the pile foundation. An abutment device is set between a pair of platform bodies 14. The abutment device includes an abutment cylinder 12, an abutment rod 13, and an abutment block 11. The abutment cylinder 12 is vertically set on the ground by measuring with a level and is installed between a pair of platform bodies 14. The abutment cylinder 12 is selected as a bidirectional cylinder. The abutment rod 13 is installed on the two output ends of the abutment cylinder 12. The abutment block 11 is integrally formed on the end of the abutment rod 13 away from the abutment cylinder 12. After the platform base 1 is set up, drive the abutment cylinder 12 so that the abutment cylinder 12 pushes the abutment rod 13 to move towards the platform base 1 until the abutment block 11 is in contact with the platform base 1. Therefore, if the abutment block 11 is in contact with the platform base 1, it means that the platform base 1 is in a vertical state.

[0043] Reference Figure 1 The platform base 1 has a platform body 14 on its top, with a through opening in the middle, through which the pile foundation passes. The top wall of the platform body 14 has mounting holes 54 adapted to the platform base 1, allowing the platform base 1 to be inserted into the mounting holes 54, thus enabling the accumulation of multiple platform bodies 14. A connecting piece 55 is detachably connected to the side wall of the platform body 14 by bolts. The connecting piece 55 is L-shaped, and a connecting hole 56 is vertically oriented through it. A fixing hole 57 is formed on the top wall of the platform body 14. The connecting hole 56 and the fixing hole 57 are coaxially aligned, and a fixing rod 58 is inserted into both the connecting hole 56 and the fixing hole 57. The fixing rod 58 passes through the connecting hole 56 and is threadedly connected to the fixing hole 57.

[0044] Reference Figure 2 and Figure 3 The platform body 14 has a connecting hole 15 on its side wall near the platform base 1. The connecting hole 15 is a square hole and is adapted to fit the top of the platform base 1. When the platform body 14 is inserted into the connecting hole 15, the top of the platform body 14 fits against the bottom wall of the connecting hole 15. A pressure sensor 2 is installed on the bottom wall of the connecting hole 15 and is installed at the four corners of the connecting hole 15. The pressure sensor 2 is connected to the buzzer 21. When the platform body 14 is inserted into the connecting hole 15, the pressure sensor 2 is triggered and the buzzer 21 sounds an alarm to help the platform body 14 get into place.

[0045] Reference Figure 2 and Figure 4 A connecting groove 33, which is square, is provided on the side wall of the platform base 1. A connecting groove 3 is provided on the inner side wall of the connecting hole 15. A push cylinder 31 is installed on the bottom wall opposite to the platform base 1. The push cylinder 31 pushes towards the side wall of the platform base 1. A connecting block 32 is installed on the output end of the push cylinder 31. The connecting block 32 is adapted to the connecting groove 33. A trigger groove 4 is provided on the side wall of the platform body 14. The trigger groove 4 is connected to the connecting hole 15. A trigger electromagnet 41 is installed on the bottom wall opposite to the platform base 1. The trigger electromagnet 41 is electrically connected to four pressure sensors 2. When all four pressure sensors 2 receive pressure signals, the trigger electromagnet 41 is energized. A displacement spring 51 is welded and fixed to the top of the platform base 1. A displacement plate 5, which is a cuboid plate, is welded and fixed to the end of the displacement spring 51 away from the platform base 1. The displacement plate 5 is located directly below the trigger electromagnet 41. A connecting magnet 42 is embedded in the center of the shift plate 5. When the trigger electromagnet 41 is energized, the connecting magnet 42 is attracted.

[0046] Reference Figure 2 , Figure 3 and Figure 5 The top of the shift plate 5 is equipped with a first trigger connector 52, and the inner side wall of the trigger groove 4 opposite to the platform base 1 is equipped with a second trigger connector 53. When the trigger electromagnet 41 is energized, the connecting magnet 42 is attracted. At this time, the shift plate 5 drives the first trigger connector 52 to move toward the second trigger connector 53. When the first trigger connector 52 is connected to the second trigger connector 53, the push cylinder 31 is controlled to be turned on, thereby driving the connecting block 32 to be inserted into the connecting groove 33 to complete the installation of the platform body 14.

[0047] The implementation principle of the pile foundation construction platform construction method in this application embodiment is as follows: First, the pile foundation construction platform is built. That is, after the abutment cylinder 12 is set vertically using a level, the platform base 1 is installed by bolts. After the platform base 1 is installed, the abutment cylinder 12 is opened, and it is observed whether the abutment block 11 is in contact with the platform base 1. If the abutment block 11 is in contact with the platform base 1, it means that the platform base 1 is placed vertically. The platform body 14 is lifted and moved onto the platform base 1, so that the platform base 1 is inserted into the connecting groove 3. If it is set stably, the pressure sensor 2 is triggered. At this time, the trigger electromagnet 41 is energized and attracts the connecting magnet 42. The shift plate 5 moves toward the trigger electromagnet 41, so that the first trigger connector 52 and the second trigger connector 53 are connected, and the connecting block 32 is pushed into the connecting groove 33 to complete the installation of the platform.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
