Device and method for observing coral sand compaction

Abstract

The invention discloses a device for observing coral sand compaction and a method for using it, which includes a loading hole, an observation area, a horizontal monitoring pipe, a camera, a vertical monitoring pipe and a signal device; the observation area is set on the coral sand soil layer out of the cylindrical structure area; the loading hole is a cylindrical structure groove opened in the center of the observation area; one end of the horizontal monitoring tube is connected to the loading hole, and the other end extends into the observation area; the vertical monitoring tube is buried vertically inside the observation area , the signal device is set in the vertical monitoring tube. The device adopts the method of embedding sensors, signal devices and imaging equipment in the coral sand soil layer, which solves the need to bury foundation piles in the prior art, which cannot be directly used for coral sand soil compaction, and the measurement effect is not good only through external observation. It has the characteristics of accurate measurement results, high degree of visualization, and can be directly used for the measurement of coral sand soil compaction-related properties.

Description

technical field [0001] The invention relates to the field of coral sand foundation engineering construction, and specifically includes a device and a use method for observing coral sand compaction. Background technique [0002] Coral sand belongs to coral reef clastic soil, which is mainly composed of coral debris and other marine biological debris. It is a special geological body with typical characteristics of loose porous, low hardness and friable. In actual engineering, it is often necessary to use coral sand as a foundation in areas where coral sand is widely distributed in sea areas. At this time, the bearing capacity and mechanical properties of coral sand are generally improved by compacting coral sand. The initial compaction method is to use large-scale machinery to vibrate or impact the coral sand. Later, in the exploration of the compaction method, in order to save money and improve the compaction effect, a method of using expansion mortar to compress the coral sa...
