Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge building foundation pile detection, in particular to a bridge building foundation pile detection device. Background Art
[0002] As an indispensable load-bearing part in the field of bridge construction, the performance of pile foundations is of vital importance. Therefore, a series of tests are often required on the pile foundations after they are completed. Among them, the test of pile foundation integrity is particularly important. The device used for low-strain testing is widely used due to its small size and simple on-site operation.
[0003] Low-strain testing is often done by manually striking the piles with tools such as hammers and force rods to test the integrity of the piles based on the excitation forces generated by the piles. This method not only makes it difficult to perform multiple identical tests on the same location, but it is also difficult to strike the piles with the same force for testing, making the results of multiple tests unrelated, resulting in low testing effectiveness and low efficiency. Utility Model Content
[0004] In view of the shortcomings of the prior art, the utility model provides a bridge construction pile detection device to solve the problems mentioned in the above background technology that it is difficult to perform multiple identical detections on the same position, and it is also difficult to use the same force to knock on the piles for detection, so that the results of multiple detections are irrelevant, resulting in low detection effect and low efficiency.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge construction pile detection device, comprising a base, a sponge cushion layer is fixedly connected to the bottom of the base, pressure blocks are fixedly connected to the two sides of the base, a sensor is fixedly connected to the top of the base, a placement slot is opened on the right side of the top of the base, a detector is arranged inside the placement slot, a column is fixedly connected to the top of the base, a top plate is fixedly connected to the top of the column, a display screen is fixedly connected to the top rear side of the top of the top plate, a movable rod is slidably connected to the middle side of the top of the top plate, a handle is fixedly connected to the top of the movable rod, a connecting block is fixedly connected to the middle part of the movable rod, a limiting block is fixedly connected to the front side of the connecting block, a limiting spring is fixedly connected to the top of the connecting block, and an impact head is fixedly connected to the bottom of the movable rod.
[0006] Preferably, the detector is electrically connected to the sensor, and the sensor is electrically connected to the display screen.
[0007] Preferably, the movable rod passes through the bottom of the top plate and extends to the outside of the bottom of the top plate.
[0008] Preferably, the number of the columns is four, and the four columns are distributed around the top of the base in a circular array, and the distances between the four columns are the same.
[0009] Preferably, the top of the limit spring is fixedly connected to the bottom of the top plate, and the limit spring is located outside the surface of the movable rod.
[0010] By adopting the above technical solution, by setting up a limit spring, a movable rod, etc. for use in combination, the movable rod can be pulled upward to move to the specified position and compress the limit spring. By loosening the movable rod, the force generated by the expansion of the limit spring is used to push the impact head to hit the foundation pile, thereby ensuring that the force of hitting the foundation pile is the same each time, thereby improving the detection effect and efficiency.
[0011] Preferably, the number of the limit blocks is two, the two limit blocks are symmetrically distributed on the front and rear sides of the connecting block, and the height of the two limit blocks is higher than the height of the connecting block.
[0012] By adopting the above technical solution, by setting limit blocks, connecting blocks, etc. for use with the movable rod, when the movable rod drives the connecting block to move upward, it will drive the limit block to move together. As the movable rod moves, the limit block will contact the bottom of the top plate to limit the displacement of the movable rod, thereby ensuring that the movable rod can move to the specified position every time, thereby facilitating subsequent detection.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The bridge construction pile detection device, by setting a pressure block, a sponge cushion layer, etc., can squeeze the sponge cushion layer through the base to fit the surface of the pile, thereby ensuring that the base will not shift, and realizing multiple detections of the same position. The force generated by the expansion of the limit spring pushes the impact head to hit the pile, thereby ensuring that the force of hitting the pile each time is the same, thereby improving the detection effect and efficiency.
[0015] 2. The bridge construction pile detection device can collect stress wave signals in the piles by setting up sensors, detectors, display screens, etc. The detector then transmits the signals to the display screen through the sensors. The staff can analyze the various values of the piles by observing the values on the display screen, and there is no need to use additional detection devices, which is convenient for the staff to use.
