Problems solved by technology

Ordinary concrete does not have anti-seepage performance. The anti-seepage and anti-corrosion method of pipe piles in related technologies is: coating asphalt coating or wear-resistant and anti-corrosion coating on the surface of pipe piles, but the coating is easily caused by friction during construction. fall off
[0004] In view of the related technologies mentioned above, the inventor believes that there is a defect that the anti-seepage performance of pipe piles needs to be improved

preparation example 1

[0042] Modified linseed vine fiber, its preparation method is as follows: remove 15kg vine stem from linseed vine, dry after washing with water, pulverize, obtain crude fiber, the length of crude fiber is 5mm, and fineness is 0.5D; Add sodium hydroxide and 0.1kg of surfactant to 60kg of water, the surfactant is sodium lignosulfonate, mix evenly to obtain a treatment solution; put the crude fiber into the treatment solution, raise the temperature to 60°C for 40 minutes, filter, wash with water, and dry Dry to obtain pretreated fibers; mix pretreated fibers, 2kg aromatic acid, 0.1kg esterification catalyst and 90kg ethanol evenly, the aromatic acid is terephthalic acid, the esterification catalyst is sodium hypophosphite, heat up to 90°C, and react for 15min Finally, filter, wash with water, and dry to obtain modified linseed rattan fiber.

preparation example 2

[0044] Modified linseed vine fiber, its preparation method is as follows: remove 20kg vine stem from linseed vine, dry after washing with water, pulverize, obtain crude fiber, the length of crude fiber is 10mm, and fineness is 3D; 1kg hydrogen oxidizes Sodium and 0.15kg of surfactant were added to 70kg of water, the surfactant was sodium dodecylbenzenesulfonate, mixed evenly to obtain a treatment solution; the crude fiber was put into the treatment solution, heated to 70°C for 35min, filtered, washed with water, Dry to obtain pretreated fiber; mix pretreated fiber, 3kg aromatic acid, 0.2kg esterification catalyst and 95kg ethanol evenly, aromatic acid is isophthalic acid, esterification catalyst is disodium hydrogen phosphate, heat up to 95°C, After reacting for 12 minutes, filter, wash with water, and dry to obtain modified linseed rattan fiber.

preparation example 3

[0046] Modified linseed vine fiber, its preparation method is as follows: remove 30kg vine stem from linseed vine, dry after washing with water, pulverize, obtain crude fiber, the length of crude fiber is 20mm, fineness is 5D; 1.5kg hydrogen Sodium oxide and 0.2kg of surfactant were added to 80kg of water, the surfactant was sodium dibutylnaphthalene sulfonate, mixed evenly to obtain a treatment solution; the crude fiber was put into the treatment solution, heated to 80°C for 30 minutes, filtered, washed with water, Dry to obtain the pretreated fiber; mix the pretreated fiber, 4kg aromatic acid, 0.3kg esterification catalyst and 100kg ethanol evenly, the aromatic acid is phthalic acid, the esterification catalyst is sodium phosphate, heat up to 100°C, and react for 10min Finally, filter, wash with water, and dry to obtain modified linseed rattan fiber.

Abstract

The invention relates to the technical field of concrete pipe piles, and particularly discloses a concrete pipe pile and a preparation method thereof.The concrete pipe pile comprises concrete and reinforcing steel bars, and the concrete is prepared from, by weight, 300-320 parts of cement; 110-130 parts of quartz powder; 650-670 parts of sand; 1320-1350 parts of stone; 8-10 parts of a superplasticizer; 120-140 parts of water; 15-30 parts of modifiedMucuna sempervirens fibers; wherein the modified Mucuna sempervirens fibers are prepared by carrying out alkaline pretreatment on Mucuna sempervirens vine stem fibers and then carrying out esterification reaction with aromatic acid. The concrete pipe pile has the advantage that the impermeability of the pipe pile is improved.

Description

technical field [0001] The application relates to the technical field of concrete pipe piles, more specifically, it relates to a concrete pipe pile and a preparation method thereof. Background technique [0002] Pipe piles are divided into prestressed concrete pipe piles and prestressed high-strength concrete pipe piles according to the concrete strength grade or effective precompression stress. The prestressed concrete pipe pile is code-named PC, the prestressed high-strength concrete pipe pile is code-named PHC, and the thin-walled pipe pile is code-named PTC. The concrete strength of PC piles shall not be lower than C60, the strength grade of thin-walled pipe piles shall not be lower than C60, and the concrete strength grade of PHC piles shall not be lower than C80. As a building component of pile foundation construction, pipe piles have been widely used in various engineering structures such as industrial and civil buildings, road and railway bridges, and port terminals...
