| titleOfInvention | grouting automatic injection smart control system and Eco-friendly ground grouting method using the same |
| abstract | The present invention is excellent in the prevention of desorption properties and water repellency even in the ground or seasons under low temperature, and reacts with moisture in the ground to improve the adhesion performance with the ground to quantify the grout composition and grout that can be maintained in the long and long term with high ground strength. Injecting at a static pressure, but eliminating the pressure difference and boosting the reaction speed, the grouting automatic control system that can realize the quality of the grout, and the friction between solid materials such as sand mixed with the grout, suppress the wear and tear between the valve seat and the valve as much as possible In addition, it is possible to improve the closing of the flow path by the valve, and the injection grouting control system including the injection pump to facilitate the use of mortar as the nozzle injection material, and the injection grouting control system to meet the obstacle or complete the injection It is intended to provide a ground grouting method capable of effectively reinforcing the ground without disruption by controlling the amount of high-performance grout composition by controlling the operation of the pump before it is made, and the powder is 30 to 90% by weight of Portland cement having a 4,000 to 6,000 cm 2 /g, Powder degree of 8,000~10,000 ㎠/g blast furnace slag 3~40% by weight, calcium hydroxide Ca(OH 2 ) 0.1~20% by weight, sodium carbonate (Na 2 CO 3 ) 0.01~3% by weight, alumina cement 0.5~5% by weight, A high-performance grout composition composed of an inorganic powder consisting of 0.5 to 5% by weight of a swelling agent and 0.1 to 5% by weight of a microcrystalline agent; When the grout of a constant flow rate is continuously introduced and reaches the injection limit value for the ground, control software is installed to reduce the instantaneous flow rate of the grout in the range of 10 to 20% of the set pressure and set flow rate, and the upper valve is installed in the return spring. Consists of a valve seat with an inverted conical valve and a corner seat that is focused in the direction of blocking the flow path, and the lower valve is a valve consisting of a valve seat with a steel ball for the valve seat and a corner seat, and urethane for sealing the toilet seat in the valve. It features a grouting auto-injection smart control management system including an injection pump without packing and a ground grouting method for grouting on the ground using the grouting auto-injection smart control management system. |
