SAND PILE BUILDING DEVICE
To provide a sand pile building device that comprises a non-contact type sand level gauge capable of continuously measuring an accurate position (sand surface) of earth and sand and capable of saving power and wiring, without being affected by the reflection noise due to a complicated shape such as piping inside a pipe, and the attenuation of a reflection level due to the adhesion of sand inside the casing.SOLUTION: A sand pile building device 10 is provided with a radio wave type sand level meter 2 using microwaves in a hollow pipe 1, and can always detect a sand surface position in the hollow pipe 1, wherein a system for measuring a propagation time of the microwaves is a pulse system.SELECTED DRAWING: Figure 1
【課題】管内の配管など複雑な形状による反射ノイズの影響、ケーシング内部への砂の付着による反射レベルの減衰などの影響を受けず、連続的に、正確な土砂の位置（砂面）を測定できる省電力、省配線が可能な非接触式砂面計を備えた砂杭造成装置を提供すること。【解決手段】中空管１内にマイクロ波を用いた電波式砂面計２を付設し、中空管１内の砂面位置を常時検出可能としたものであって、マイクロ波の伝播時間測定方式がパルス式である砂杭造成装置１０。【選択図】図１
