Problems solved by technology

If the underground water cannot be discharged through the blind drainage pipe in time, it will accumulate behind the tunnel lining. When the water pressure accumulates too much, water seepage and leakage will occur in the tunnel, which greatly shortens the service life of the tunnel and affects the structural safety of the tunnel project. Long-term operations pose a serious threat

preparation example Construction

[0039] The present application also provides a method for preparing the above-described dredging cleaning agent, comprising: the composite organic acid, penetrant, corrosion inhibitor and scale inhibitor added to the water mixture, that is, to dredge the cleaning agent.

[0040] In one embodiment, the mixing of the above preparation method comprises: the scale inhibitor is first added to the water mixture, and then added corrosion inhibitor, so that the scale inhibitor and corrosion inhibitor are mixed evenly, and then add the composite organic acid and the osmotic agent in turn, mixing and stirring until the solid powder is completely dissolved, the solution has no precipitation.

[0041] The dredging cleaning agent prepared in the present application can be directly used for dredging and cleaning of the blind pipe of tunnel drainage, and no further dilution is required. In the blocked drainage blind pipe at both ends of the connection of the plastic pipe to form a circuit, the p...

Embodiment 1

[0044]The present embodiment provides a dredging cleaning agent, as a percentage of mass, comprising 18% citric acid and oxalic acid complex organic acid, 2% fatty alcohol polyoxyethylene ether JFC, 2% corrosion inhibitor, 78% water and scale inhibitor polyaspartic acid (PASP). Among them, the DOSAGE OF PASP is 10mg per liter of water; the corrosion inhibitor is a composite corrosion inhibitor, including 20% hexamethylenetetraamine, 60% triphenylcyclimidazolium quaternary ammonium salt and 20% OP-10.

[0045] The specific preparation method of the dredging cleaning agent is: 7.8mg of polyaspartic acid is first added to 780g of water for stirring, and then 20g of corrosion inhibitors (including 4g of hexamethylenetetraamine, 12g of triphenylcyclimidazolium quaternary ammonium salt and 4g of OP-10), continue to stir until the two are mixed evenly, sequentially add 180g of citric acid and oxalic acid of the composite organic acid, 20g of JFC, continue to stir until the solution is n...

Embodiment 2

[0047] The present embodiment provides a dredging detergent, as a percentage of mass, comprising 21% citric acid and malic acid complex organic acid, 2.5% alkylphenol polyoxyethylene ether JFC-1, 2.5% hexamethylene tetraamine, 74% water and scale inhibitor threonine - urea grafted modified polyaspartic acid (PASPTU), wherein the dosage of PASPTU is added to 12.5mg per liter of water

[0048] The specific preparation method of the dredging cleaning agent is: 9.25mg of PASPTU is first added to 740g of water for stirring, and then 25g of hexamethylenetetramine is added, continue to stir until the two are mixed evenly, and then add 210g of citric acid and malic acid of the complex organic acid, 25g of JFC-1, continue to stir until the solution has no precipitation, you can get the dredging cleaning agent.

Abstract

The application provides a dredging cleaning agent and a preparation method thereof. The dredging cleaning agent includes 18% to 30% compound organic acid, 2% to 3% penetrating agent, 2% to 3% corrosion inhibitor, 64% to 78% Water and antiscalant, wherein the dosage of antiscalant is 10mg~20mg per liter of water. The dredging cleaning agent is prepared by adding compound organic acid, penetrating agent, corrosion inhibitor and scale inhibitor into water and mixing. The dredging cleaning agent can remove the crystalline scale deposited by karst water in the blind drainage pipe of the tunnel, which can affect the normal growth of crystals, effectively prevent the further formation of crystals, and achieve a long-term scale inhibition mechanism. The raw materials used are green and degradable, and are not easy to corrode Drainage facilities ensure the safety of the tunnel structure; and the preparation method is simple, which is highly safe for operators, and the waste water after cleaning can be directly discharged into the environment, which is a green and environmentally friendly cleaning agent.

Description

Technical field [0001] The present application relates to the field of cleaning agent technology, in particular, to a dredging cleaning agent and a method of preparation thereof. Background [0002] Because there are many mountainous and hilly terrain in China, tunnels are the most common construction projects in order to save construction costs when building traffic routes. Tunnels are generally built on mountains or underground, and many times there will be different degrees of leakage. Especially in karst areas, the geological conditions are more complex, and when the tunnel project passes through the karst area, the existence of karst will seriously affect the construction safety and later operation of the tunnel. In order to avoid and reduce the harm of karst water to the tunnel project, China's tunnel workers use molded concrete lining as the basic measure for waterproofing and water blockage, and then artificially set up a drainage system to discharge the underground seep...
