APPARATUS REAL TIME AUTOMATIC INSTRUMENT OF NEW SAND DRAIN METHOD AND NEW SAND COMPACTION PILE METHOD WITH EXCELLENT CONSTRUCTION QUALITY

摘要

PURPOSE: A real-time automatic measuring device for sand drain and sand compaction pile methods for high-quality construction is provided to ensure a worker and a construction inspection company to ensure the reliability of construction quality and visual reading on construction work by automatically recording and displaying measuring data including the penetration and impression positions and verticality of a casing, and a tilt weight position as a track and a diagram in real time. CONSTITUTION: A real-time automatic measuring device for sand drain and sand compaction pile methods for high-quality construction comprises a reader, a vibration hammer, a casing, a verticality sensor, a tilt depth sensor, a penetration depth sensor, a displacement sensor, and a controller. The reader is vertically installed on the front of an endless-track vehicle. The vibration hammer is installed in order to ascend and descend in the longitudinal direction of the reader. The casing is installed on the lower part of the vibration hammer and is penetrated or impressed in the ground. The verticality sensor is installed on one side of the lower part of the reader to measure verticality. The tilt depth sensor is installed on one side of the reader and measures the height of sand, which is put into the casing.
