Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a sand and gravel geological PHC pipe pile positioning tool. Background Art

[0002] In the construction industry, especially when dealing with complex geological conditions such as gravel and sandy ground, PHC (prestressed high-strength concrete) piles are widely used as an efficient and economical pile foundation in the construction of bridges, high-rise buildings, and port terminals. However, the unique unevenness, looseness, and high compressibility of gravel and sandy ground pose numerous challenges to the construction of PHC piles. These geological characteristics can easily cause the piles to shift or tilt during sinking, thereby affecting the bearing capacity of the pile foundation and the overall stability of the project.

[0003] Traditional PHC pile construction methods rely heavily on the construction crew's experience and on-site observations to determine pile verticality and positional accuracy. However, this method is subject to significant subjectivity and uncertainty, making it difficult to accurately detect and address pile offset or tilt issues. This is particularly true in sandy and gravel geological conditions, where the complex and variable geological conditions make it even more difficult to ensure accurate pile positioning and construction quality using traditional methods.

[0004] Therefore, developing a tool that can effectively address the PHC pile positioning challenge in sandy and gravel geological conditions is crucial. This tool needs to be able to monitor the verticality and positional accuracy of the piles in real time, promptly detecting and warning of pile deviation or tilt. This provides accurate data support to construction personnel, ensuring smooth pile construction and effective quality control. Utility Model Content

[0005] The purpose of the utility model is to provide a PHC pipe pile positioning tool in sand and gravel geology, which is used to solve the technical problems that PHC pipe piles are difficult to position under traditional sand and gravel geological conditions and difficult to detect in time when the PHC pipe piles are offset or tilted.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a sand and gravel geological PHC pile positioning tool, the sand and gravel geological PHC pile positioning tool comprising:

[0007] A fixing portion, which is sleeved around the top of the PHC pile and has a plurality of mounting seats;

[0008] A plurality of transmitters, each of which is mounted on a respective mounting base, and the transmitting direction of the transmitter is vertically downward;

[0009] A receiving ring is provided on the lower pile surface, and the center of the receiving ring coincides with the lower pile point. A plurality of receivers are provided on the receiving ring, and the transmitter and the receiver are located on the same cylindrical surface.

[0010] In one embodiment, the fixing portion is a clamp.

[0011] In one embodiment, the emitter is a laser emitter.

[0012] In one embodiment, the device further comprises a data processing unit electrically connected to the receiver, configured to receive and analyze data transmitted by the receiver, display verticality and position information of the PHC pile in real time, and issue an alarm signal when deviation or tilt is detected.

[0013] In one embodiment, the data processing unit has a data storage function, and the data processing unit records and stores the PHC pile positioning data during each construction process.

[0014] In one embodiment, the fixing portion is made of high-strength, corrosion-resistant material.

[0015] One or more of the above technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

[0016] The PHC pile positioning tool for gravel and sandy terrain, provided in an embodiment of the present invention, uses a fixed portion to precisely mount multiple transmitters on the top of the PHC pile. Combined with a receiver on a receiving ring, this tool enables real-time monitoring of the pile's verticality and positional accuracy. This real-time monitoring method significantly reduces the subjectivity and uncertainty of human judgment, improves construction accuracy, and ensures that the piles are accurately installed according to design requirements. In gravel and sandy terrain, piles are prone to drift or tilt. The positioning tool of this application provides feedback via a receiver as soon as the pile shifts or tilts (when drift or tilt occurs, the downward-transmitted signal from the transmitter does not accurately reach the receiver, resulting in the receiver not receiving the signal from the transmitter). This feedback from the receiver informs construction workers of the pile shift or tilt, allowing them to quickly detect and take corrective measures to prevent further drift or tilt, thereby ensuring the verticality and stability of the pile. Furthermore, the verticality and positional accuracy of the pile directly impact the bearing capacity of the pile foundation and the overall stability of the project. By ensuring the precise positioning of the piles, the positioning tool of this application provides a strong guarantee for project quality and reduces quality issues and safety hazards caused by pile shift or tilt.

[0017] In summary, the sand and gravel geological PHC pile positioning tool of the present application has significant beneficial effects in improving construction accuracy, timely detecting and correcting deviations, and ensuring project quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figures 1 to 2 The embodiment of the present application provides a PHC pile positioning tool for sand and gravel geology, including a fixing part 1, multiple transmitters 2, and a receiving ring 3, wherein the fixing part 1 is wrapped around the top of the PHC pile 5, and multiple mounting seats 11 are provided on the fixing part 1; the transmitters 2 are installed on each mounting seat 11, and the transmitting direction of the transmitter 2 is vertically downward; the receiving ring 3 is arranged on the lower pile surface 4, and the center of the receiving ring 3 coincides with the lower pile point, and multiple receivers 31 are provided on the receiving ring 3, and the transmitters 2 and the receivers 31 are on the same cylindrical surface.

[0028] When constructing the PHC pile 5, the receiving ring 3 can be first installed on the lower pile surface 4, and ensure that the center of the receiving ring 3 coincides with the pile installation point. Then, the fixing part 1 is installed on the top of the PHC pile 5. The PHC pile 5 is moved by the static pile driver until the receiver 31 receives the signal (such as a laser signal) emitted by the transmitter 2. This indicates that the PHC pile 5 is now directly above the pile installation point and is in a vertical state, thereby ensuring the accuracy of the pile installation.

[0029] In this embodiment, the transmitter 2 is installed on the PHC pile 5 through the fixing part 1, and the receiver 31 on the receiving ring 3 is used to receive the signal sent by the transmitter 2. When the receiver 31 receives the information, it means that the PHC pile 5 is in a vertical state and has not deviated. Therefore, when the PHC pile 5 is constructed in gravel geology, if the PHC pile 5 deviates or tilts due to the unevenness, looseness and high compressibility of the gravel geology, the positioning tool in this application can detect it in time to facilitate correction.

[0030] Specifically, the mounting seat 11 can be fixed on the fixing portion 1 by welding. An arc-shaped slot is provided on the mounting seat 11, and the emitting portion is fixed in the arc-shaped slot.

[0031] In one embodiment, the fixing portion 1 is a clamp. The fixing portion 1 of the clamp structure is easy and convenient to install, and is firm and reliable after installation, thereby improving construction efficiency and reducing positioning errors caused by unstable fixation.

[0032] In one embodiment, the transmitter 2 is a laser transmitter 2. The laser beam has the characteristics of good linearity, strong directionality, high brightness, etc., can be transmitted over long distances and is not easily affected by ambient light, thereby improving the accuracy and reliability of the positioning of the PHC pile 5.

[0033] In one embodiment, the system also includes a data processing unit, electrically connected to the receiver 31. The data processing unit receives and analyzes data transmitted by the receiver 31, displays the verticality and position of the PHC pile 5 in real time, and issues an alarm signal when deviation or tilt is detected. This design significantly improves construction safety and efficiency, enabling timely detection and correction of deviations during construction, ensuring accurate installation of the PHC pile 5. Furthermore, the data processing unit's recording and storage capabilities provide strong support for subsequent construction analysis and quality traceability.

[0034] In one embodiment, the data processing unit has a data storage function that records and stores the positioning data of the PHC piles 5 during each construction process (including but not limited to time, offset, inclination, and other data). This data storage function enables the complete recording and preservation of the positioning data of the PHC piles 5 during each construction process. This data is crucial for assessing construction quality, tracing issues, and providing a reference for subsequent similar projects. Through data analysis, construction plans can be continuously optimized, improving both quality and efficiency.

[0035] In one embodiment, the fixing portion 1 is made of high-strength, corrosion-resistant materials (such as stainless steel, aluminum alloy, etc.), thereby effectively improving the durability and stability of the positioning tool in harsh construction environments.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
