Description

Technical Field

[0001] The utility model belongs to the technical field of new energy wind power foundation, and particularly relates to a measuring device for the position of residual slurry in precast pipe piles. Background Art

[0002] In the rapid advancement of wind power generation projects, precast pipe piles have become the preferred material for wind turbine pile foundations due to their significant advantages such as high strength, high quality, and high construction efficiency. However, despite their excellent performance, the challenges in their manufacturing process cannot be ignored, especially the problem of residual slurry that easily appears inside hollow precast pipe piles.

[0003] The formation of residual slurry mainly stems from improper control or incomplete cleaning in the grouting process during production. If these residues accumulate inside the pipe pile, especially near the top, they will directly pose an obstacle to subsequent construction. As a key component for enhancing the structural strength and stability of the pipe pile, the accurate and smooth placement of the steel reinforcement cage is crucial. Once the residual slurry hinders the placement of the steel reinforcement cage, it will not only affect the overall structural strength of the pipe pile but also seriously interfere with the construction quality of concrete core filling, further possibly leading to insufficient bearing capacity of the pile body and affecting the stability and safety of the wind power tower.

[0004] Even more seriously, since the existing pipe pile quality inspection system mainly focuses on the inspection of appearance and dimensions, there are obvious deficiencies in the accurate detection of internal residual slurry. Relying on the visual judgment of on-site personnel is not only inefficient but also has large errors, making it difficult to accurately grasp the position and thickness of the residual slurry. This information asymmetry and uncertainty undoubtedly increase the risks during the construction process. Once the situation where the steel reinforcement cage cannot be placed or the core filling quality does not meet the standards occurs, it often takes a lot of time and resources to handle, thus delaying the construction period and increasing the project cost. Content of the Utility Model

[0029] Embodiment

[0030] See Figure 1 , a measuring device for the position of residual slurry in a precast pipe pile, comprising a laser rangefinder 1, the laser rangefinder 1 is installed on a support member, the support member is buckled on the top of the precast pipe pile, and the laser beam of the laser rangefinder 1 is directed at the residual slurry in the pipe pile. The laser rangefinder 1 is used to detect the position of the slurry inside the precast pipe pile. The laser rangefinder 1 measures the distance by emitting laser light and receiving the reflected signal.

[0031] The support member includes buckling feet 2, two buckling feet 2 are provided, and a telescopic guide rod 3 is connected between the two buckling feet 2. The buckling feet 2 include a horizontal part and a vertical part, and the included angle between the horizontal part and the vertical part is 90 degrees. The laser rangefinder 1 is installed on the vertical part. The vertical parts of the two buckling feet 2 are arranged in parallel. The telescopic guide rod 3 is connected between the horizontal parts of the two buckling feet 2. The telescopic guide rod 3 is provided with scales. The telescopic guide rod 3 adopts a spring caliper. The length and strength of the telescopic guide rod 3 are designed to ensure that a measuring device for the position of residual slurry in a precast pipe pile can successfully clamp the precast pipe pile and measure the wall thickness of the pipe pile. The telescopic guide rod 3 is usually made of a light and strong material, such as plastic or alloy material, so that the operator can easily operate it.

[0032] The laser rangefinder 1 is provided with a controller. The laser rangefinder 1 is provided with a display screen. The controller adopts a multi-functional controller, which is used to start and stop the operation of the detector and adjust the measurement parameters. The controller usually has two operation modes: automatic and manual, which is convenient for users to select according to different needs. The display screen adopts a high-resolution liquid crystal display screen to display the measurement results in real time. The display content includes the position, quantity and possible distribution map of the residual slurry, providing intuitive data for the operator.

[0033] A measuring device for the position of residual slurry in a precast pipe pile realizes the accurate measurement of the position of residual slurry inside the precast pipe pile through the coordinated work of the detection laser of the laser rangefinder 1, the signal processing unit, the display screen, the controller and the telescopic guide rod 3. The detailed working principle of a measuring device for the position of residual slurry in a precast pipe pile is as follows:

[0034] 1. Laser rangefinder:

[0035] Emitting a laser beam: The laser rangefinder is designed to be able to emit a thin and high-intensity laser beam, which can penetrate the opening of the precast pipe pile and go deep into its interior. The emission angle and direction of the laser beam need to be precisely controlled to ensure that various areas inside the pipe pile can be scanned, especially those positions where residual slurry may exist.

[0036] Receiving reflected light: When the laser beam encounters the mud interface inside the pipe pile, part of the light is reflected. These reflected lights are then captured by the receiver of the laser rangefinder. The receiver needs to have high sensitivity so as to be able to capture weak reflected signals, especially when the mud layer is thin or the reflecting surface is uneven.

[0037] Calculating the distance: The distance is calculated by measuring the time difference between the laser emission and reception. The time measurement system built into the laser rangefinder records the time difference between the laser emission and the reception of the reflected light. Using the principle of the constant speed of light, the distance traveled by the laser beam, that is, the distance from the inner wall of the pipe pile to the mud interface, can be calculated through this time difference. By emitting and receiving lasers at different positions inside the pipe pile, the distribution of mud inside the pipe pile can be mapped.

[0038] 2. Telescopic guide rod:

[0039] The telescopic guide rod is used to guide the detector to the designated position of the precast pipe pile. The telescopic guide rod is usually made of lightweight and strong materials and can adjust its length to meet the measurement requirements of different pipe pile thicknesses and measure the pipe pile wall thickness at the same time.

[0040] 3. Signal processing unit:

[0041] The signal processing unit of the laser rangefinder 1 converts the analog signal into a digital signal, and calculates the position and distribution of the remaining mud according to the time difference or intensity of the received signal. Collect and sort out the positions of the remaining mud, and calculate the positions and distribution of the remaining mud. The processed data is displayed in the form of charts, images, etc., so that the operator can intuitively understand the distribution and severity of the remaining mud.

[0042] 4. Display screen:

[0043] The display screen of the laser rangefinder 1 displays the digital processing results, providing an intuitive reference for the operator to facilitate the operator's understanding and judgment. The display screen is connected to the signal processing unit and is used to display the measurement results and data analysis results. The display screen should have high resolution and clear display effect so that the operator can clearly see every detail. Provide a friendly interaction interface, allowing the operator to input relevant parameters, select measurement modes, view historical data, etc. At the same time, an alarm function can also be set to remind the operator in time when abnormal situations are detected.

[0044] Specific usage operation of a device for measuring the position of remaining mud in precast pipe piles:

[0045] Adjust the telescopic guide rod to an appropriate length, and use the snap feet to hold the pipe pile. At this time, the wall thickness of the pipe pile can be measured to check if it meets the requirements. In the second step, turn on the laser rangefinder and measure the distance from the residual slurry inside the pipe pile to the top of the pile. At this time, the specific data can be viewed on the display screen. If there is no specific value, it can be determined that there is no residual slurry at the installation section of the device, and then the measurement of the next point can be carried out.

[0046] Generally, four points are measured on one pipe pile, and one point is measured every 90° at the top of the pipe pile to confirm the thickness of the residual slurry inside the pipe pile. For the specific method, please refer to Figure 2 Schematic diagram of the installation of the measuring device at the opening of the top of the pipe pile.

[0047] Upon reading the above description, many embodiments and many applications beyond the provided examples will be obvious to those skilled in the art. Therefore, the scope of this teaching should not be determined with reference to the above description, but rather should be determined with reference to the full scope of the foregoing claims and the equivalents thereof.
