Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] First, put 1 part of P.032.5 cement, 3 parts of medium sand, and 7.5 parts of crushed stone with a particle size of 5-40) mm into the concrete mixer for 40 seconds, and then add 4 parts of pipe pile waste slurry and 0.02 parts of pump while stirring. Send agent, then wet mix for 40 seconds to make concrete mixture.

[0025] Put this mixture into the mold of the prefabricated component, and use the flexible shaft vibrating rod to vibrate in the "intensive vibrating method", that is, the distance between the vibrating points is 1 times the radius of action of the vibrating rod; Fully vibrate the feeding side to keep the concrete mixture in the mold rising horizontally without obvious air bubbles escaping, and then perform curing according to ...

Abstract

The invention relates to a method for producing concrete water conservancy prefabricated-part with tubular pile waste water slurry. Firstly concrete, medium sand and gravel are launched into a concrete mixer to be mixed for 30 seconds to 60 seconds according to proportion by weight; and then the tubular pile waste water slurry is added when stirring; the quantity of the water slurry added into issubject to slump constant of the concrete mix which is between 30 mm to 120mm; the concrete mix is produced after the wet mixture is acted for 30 to 60 seconds. And then the concrete mix is launched into a prefabricated-part mould; a concentrated vibro is adopted for processing, and the distance between vibro points is 0.8 times to 1.2 times of the working radius of a vibrating spear. When in pouring, the concrete mix needs to be processed for pouring layer upon layer in the mould in a horizontal plane rising way. At last maintenance is processed according to a conventional maintenance process method. Aiming at the mechanical property requirements of the concrete water conservancy prefabricated-part, the pressive strength grade of the produced concrete water conservancy prefabricated-partis C30 through improving the mix proportion of the concrete and the pouring technology; the appearance quality measures up to the standard requirements.

Description

Technical field: [0001] The invention relates to a production and construction process of a water conservancy prefabricated component, in particular to a method for producing concrete hydraulic prefabricated components by using pipe pile waste slurry. Background technique: [0002] Pipe pile waste slurry is the waste liquid produced during the centrifugal forming process of pipe piles. According to statistics, 1m 3 The pipe pile concrete is centrifuged to produce about 0.05m 3 of waste pulp. Its main components are cement, fine sand, water, a small amount of dust and admixtures. The content of cement in the waste slurry reaches 60%. [0003] The past treatment method for the generated pipe pile surplus slurry (waste slurry) is to directly discharge it on the open space or pour it into a puddle or farmland, and then dig it out for landfill after it is naturally hardened. Because the waste slurry contains a large amount of alkaline substances, it can take up to a hundred ...
