The invention discloses an underwater displacement sensor of a load box, comprising: installing a plurality of displacement protection casings on the load box; placing an underwater magnetic displacement sensor in the displacement protection casing, and connecting the underwater magnetic displacement sensor with a cable , the underwater magnetic displacement sensor includes a magnetic rod and a stainless steel tube protective sleeve, the magnetic rod is inserted into the stainless steel tube protective sleeve, and a magnetic ring is arranged on the top periphery of the stainless steel tube protective sleeve. The lower half of the stainless steel tube protective sleeve is a counterweight. A retaining ring is installed on the head of the magnetic displacement sensor inserted into the protective sheath of the stainless steel tube. The stainless steel tube protective sleeve is installed in the displacement casing. The magnetic displacement sensor of the present invention has the advantages of underwater work, high precision and high reliability, and solves the traditional problem of low measurement accuracy and inconvenient measurement by connecting a steel bar at the bottom of the load box and transmitting it to the ground to measure displacement in the displacement casing. question.
Description
technical field [0001] The invention belongs to the technical field of construction equipment, and in particular relates to an underwater displacement sensor of a load box. Background technique [0002] Pile foundation detection The load box underwater displacement detection, the load box is pre-buried with the foundation pile to a depth of tens of meters in the ground, when the pressure is applied, the lower pile body of the load box will have a downward displacement, and the load box pile body will have an upward displacement. The previous method is to connect steel bars at the bottom and top of the load box as a displacement guide rod, which transmits the displacement to the ground for displacement measurement, which has the disadvantages of low measurement accuracy and inconvenient measurement. [0003] The purpose of the present invention is to remove the previous conductive steel bar, directly put the load box underwater displacement sensor into each detection point of...
