A multi-ball point pre-embedded pile for early warning of geological disasters

Abstract

The invention discloses a multi-ball point pre-buried pile for geological disaster early warning, which belongs to the field of geological disaster early warning. It is a multi-ball point pre-buried pile for geological disaster early warning. Through the setting of the pre-buried pile, when the geological subsidence occurs, The pre-breaking sinking rod is subjected to downward pressure, and acts on the lower outer marking end, so that the surface of the marking ball is notched, and the colored sand inside overflows. When the pre-breaking sinking rod breaks, the outer marking end recovers after losing the pressing force. , the gap disappears, and the sand mining stops overflowing. When the pre-embedded pile detects that there is subsidence, the soil near the pre-embedded pile can be excavated, and the specific subsidence situation can be judged according to the amount of colored sand. , the sharp thorns gradually approach the inner photosphere until it will pierce, causing the fluorescent liquid inside to overflow, which can be used for auxiliary marking of geological subsidence, which will help the staff to intuitively judge the situation of geological subsidence, and facilitate corresponding Countermeasures to reduce potential safety hazards.

Description

technical field [0001] The invention relates to the field of early warning of geological disasters, in particular to a multi-ball point pre-embedded pile for early warning of geological disasters. Background technique [0002] Geological disasters mainly refer to collapses (that is, dangerous rock masses), landslides, debris flows, karst ground collapses, and ground fissures. sexual. Geological environmental disasters refer to hazards caused by regional geological and ecological environment variations, such as regional land subsidence, seawater intrusion, desertification in arid and semi-arid areas, soil erosion in rocky mountain areas, rocky desertification, and regional geological structure subsidence Frequent floods in plains or basins, etc. These problems are usually caused by multiple factors and occur slowly. The geological circles often call them slow-changing geological disasters. [0003] my country's definition of geological disasters is the geological action (ph...

AI Technical Summary

Problems solved by technology

[0004] The monitoring of geological subsidence is usually realized by pre-embedded rods, but the pre-embedded rods in the prior art can only detect the occurrence of geological subsidence. The specific degree of subsidence generally depends on the analysis of various data, and rarely It can intuitively reflect the degree of geological subsidence. For the on-site construction workers, there are certain difficulties in performing maintenance, which leads to greater safety hazards
