Description
Technical Field
The utility model relates to a bridge foundation pile detects technical field, specifically is a hammering device that is used for bridge foundation pile integrality in labour to detect.
Background
In-service bridge foundation pile integrity detection is technically very complex. The types and structures of the bridge are various, and the pile foundations below the ground are more complicated and variable. In the detection process, the pile length, the pile diameter and the pile body strength of the foundation pile and the lithological mechanical properties of the stratum where the foundation pile is located need to be considered. The side multi-speed reflection wave method is a new technology for detecting the integrity of the foundation pile of the in-service bridge. The method needs a proper excitation device to overcome the defect that the incident stress wave caused by the adverse factors of large section of the pile body, long pile length, strong soil resistance and the like is quickly absorbed. The proper excitation device can enable the stress wave to have enough energy to be transmitted to the position of the defect of the pile body or the impedance change part such as the pile bottom and the like, an uplink stress reflected wave is generated and received by the sensor, the pile length and the defect are further determined, and the spatial position and the degree of the defect are evaluated.
At present, the vibration excitation device is mainly a hand hammer made of steel materials. For the integrity detection of the foundation pile of the in-service bridge, the defects of the pile body are difficult to accurately detect only by using a hand hammer, so that misjudgment or missed judgment is often caused, and serious potential safety hazards are caused to the engineering. The reason is that the in-service pile is usually a cast-in-place pile, the diameter and the length of the pile are both large, and the defects of the bottom and the deep part of the pile can be found only by using a hand hammer with large mass. If the hammer is light or the frequency of the hammer head is high, the stress wave is difficult to propagate far, and the deep defect of the pile body cannot be found; if the hammer is too heavy or the frequency of the hammer head is too low, the pulse width of the excited stress wave is too large compared with the defect size, and the wavelength of the stress wave is too long, the shallow defect of the pile body cannot be found. It follows that hammering is very important for in-service foundation pile integrity testing.
In response to the above-mentioned need, a hammering device for in-service bridge foundation pile integrity detection is now provided.
