Underwater pile foundation low strain dynamic testing device
The invention discloses an underwater pile foundation low strain dynamic testing device. A knocking hammer and a stress wave receiving probe are integrated in one stress wave generating and receiving device. Meanwhile, the automated falling and retracting of the knocking hammer are achieved. The stress wave generating and receiving device is fixed to the top of a pile foundation through the combination of a balancing weight and a fixing device. An adhesive attachment gelatinous layer is arranged at the lower end of the stress wave receiving probe. A water isolation door which can be opened and closed is designed in the lower portion of a left cavity. When the stress wave generating and receiving device is pressed on a pile, a frame block is pressed on the pile and sealed together with a pile cap, and the water isolation door is then opened. By means of the structure, the left cavity can be kept in the non-water state all the time, and the phenomenon that the knocking effect is influenced when the knocking hammer falls and rubs water is avoided. The stress wave generating and receiving device is provided with a pile hooking structure, wherein the pile hooking structure comprises a pile grabbing device. The underwater pile foundation low strain dynamic testing device has the advantages that the underwater pile foundation low strain dynamic testing device can be used in deep water under high pressure, the knocking hammer and the detection probe are combined, the knocking hammer can knock on the pile under the water-free environment, and the stress wave generating and receiving device is good in fixing effect.
