Embodiment 1

[0022] Choose the pipe jacking made of ordinary concrete, destroy the pipe jacking, take 500g pipe jacking block, put it into the simulated acidic soil test solution, the pH of the acidic soil test solution is 5-6, and extract it from the southeast hilly red soil, soak 1 piece Month, weigh again, statistical weight data, marked as A.

Embodiment 2

[0024] The pipe jacking prepared by the following ratio is selected, and the concrete is composed of the following weight ratio, 43 parts of coal gangue, 25 parts of limestone, 16 parts of calcium lignosulfonate, 17 parts of borax, 39 parts of calcium sulfate, and 25 parts of calcium carbonate. Destroy the pipe jacking, take 500g pipe jacking block, put it into the simulated acidic soil test solution, the pH of the acidic soil test solution is 5-6, it is obtained by leaching from the southeast hilly red soil, soak for 1 month, weigh again, and calculate the weight data , labeled B.

Embodiment 3

[0026] The pipe jacking prepared by the following ratio is selected, and the concrete is composed of the following weight ratio: 35 parts of coal gangue, 20 parts of limestone, 9 parts of calcium lignosulfonate, 13 parts of borax, 30 parts of calcium sulfate, and 19 parts of calcium carbonate. Destroy the pipe jacking, take 500g pipe jacking block, put it into the simulated acidic soil test solution, the pH of the acidic soil test solution is 5-6, it is obtained by leaching from the southeast hilly red soil, soak for 1 month, weigh again, and calculate the weight data , labeled C.

Abstract

The invention relates to the field of top pipe manufacturing and discloses anti-acid concrete for manufacturing a top pipe. The anti-acid concrete is characterized by being prepared from the following components in parts by weight: 35 to 50 parts of coal gangue, 20 to 30 parts of limestone, 9 to 21 parts of calcium lignosulfonate, 13 to 21 parts of borax, 30 to 45 parts of calcium carbonate, 19 to 32 parts of calcium sulfate, 2 to 6 parts of epoxy resin, 5 to 10 parts of fluorocarbon emulsion, 4 to 8 parts of mesh quartz sand, 0.2 to 0.8 part of hydroxy propyl methyl cellulose, 1 to 5 parts of tributyl phosphate, 1 to 2 parts of polyvinyl alcohol and 2.4 to 3.2 parts of polysilicone. The anti-acid concrete disclosed by the invention achieves the aims of permanent waterproof, moisture-proof and chemical corrosion resisting properties. The problems that the existing top pipe manufactured on the basis of common concrete has cracks and is corroded in acidic soil are solved.

Description

technical field [0001] The invention relates to the field of pipe jacking manufacture, in particular to an acid-resistant concrete used for making pipe jacking. Background technique [0002] In the existing pipeline laying, the pipe jacking construction is mostly used, and the pipe jacking construction is a non-excavation construction method, which is a pipeline burying construction technology without excavation or less excavation. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the earth away. After one section of pipe has been jacked into the soil layer, the second section of pipe will continue to be jacked. Its principle is to push the tool pipe or roadheader from the working pit through the soil layer to the receiving pit by means of the thrust of the main top oi...
