The working principle of the geological disaster rainfall emergency monitoring and early warning system provided by the invention is as follows:
s1, investigating the area to be monitored, and dividing the area to be monitored into a plurality of monitoring points according to the disaster condition;
s2, selecting proper brackets at different monitoring points, and installing rainfall monitoring equipment to measure rainfall data, inclination angle data and displacement data of the current monitoring point position;
and S3, the remote monitoring terminal comprehensively monitors the data of each monitoring point, and sends alarm information to the outside when the server judges that the rainfall parameter exceeds the safety threshold.
In addition, the adhesive is prepared from a nano silicate modified polyurethane material, and is divided into a low-viscosity high-fluidity adhesive for embedded installation by adjusting a double-component formula; secondly, the medium-viscosity quick-solidification type is used for surface-mounted installation of bedrock.
The nano silicate modified polyurethane has the excellent characteristics of no influence on underwater consolidation, no pollution to water environment, high mechanical strength such as consolidation bonding strength, consolidation body compression, tension and shearing and the like, and is more and more widely applied to underground engineering such as water conservancy and hydropower engineering, tunnel subways, mines and the like. The nanometer silicate modified polyurethane consists of mainly two components, one is nanometer modified silicic acid solution, the other is prepolymer composite liquid of polymeric MDI and polypropylene alcohol, and the reaction process mainly comprises three parts: the polymeric MDI reacts with water to generate carbamate which reacts with carbon dioxide, and the carbon dioxide reacts with sodium silicate to generate a silicon dioxide tree-shaped network, and sodium carbonate molecules and composite water macromolecular crystals thereof are formed and embedded between inorganic and organic tree-shaped networks. The three parts are simultaneously carried out and are respectively independent systems, and are mutually cooperated, mutually promoted and interacted. The concretion is the interpenetration and coupling of inorganic and organic tree networks in the forming process, and the generated concretion has excellent mechanical properties (compression, tension, shear and bonding strength). The inorganic silicon dioxide reticular structure contributes to the hardness and the strength of the concretion, the organic amino formic acid resin reticular body contributes to the toughness and the cohesiveness of the concretion, and the silicon dioxide molecules and the sodium carbonate molecules have excellent wettability similar to the polarity of the surface of the coal rock mass, are stronger than the traditional organic polymer and have high cohesiveness to the coal rock mass. And because the inorganic tree-shaped network is formed by interpenetrating with the organic tree-shaped network, the solidified substance has better toughness and deformability, and is much better than pure inorganic substances. The reaction process and mechanism are as follows:
1) organic polymer reaction:
the isocyanate groups of the polymeric MDI react with water in the silicate solution to form a urethane complex and carbon dioxide gas as shown below:
H2O+R1-N＝C＝O→R1-NH2+CO2
R1-NH2+R2-N＝C＝O→R1-NH-CO-NH-R2(polyurea polyurethane)
Wherein R is1、R2Comprises the following steps: R-CONH-R' -N ═ C ═ O (isocyanate terminated polyurethane prepolymer)
2) Inorganic polymer reaction:
the carbon dioxide gas reacts with the silicate micro-colloidal solution in the silicate solution to generate inorganic carbonate crystals and an inorganic dendritic network structure of ortho-silicic acid macromolecules. As follows:
CO2+Na2O·xSiO2·yH2O→Na2CO3+(SiO2)x(H2O)y
