Abstract
The invention discloses a (super) high strength prestressed concrete pipe pile which is poured by concrete. Each cubic metre of the concrete comprises following raw materials by weight parts: 250+_ 10parts of cement, 135+_10 parts of grinded quartz sand, 190+_10 parts of surplus paste, 580+_50 parts of medium sand, 350+_50 parts of small stones, 1100+_100 parts of rough stones, water reducing agent the weight parts of which are corresponding to 0.5-0.7526154000f total weight parts of concrete and grinded quartz sand, and adequate water. Wherein, the weight concentration of gelled material insurplus paste is 30-40 According to the invention, surplus paste generated during pipe pile production is utilized sufficiently, so that excellent environmental protection benefit is obtained. Pipe piles of high-strength prestressed concrete with intensity up to c95 are fabricated by using low rubber materials.
Description
Technical field
The present invention relates to a kind of high-strength prestressed concrete pipe pile.
Background technology
At present along with socioeconomic continuous development, the demand of (surpassing) high-strength prestressed concrete pipe pile that is applied to infrastructure and highrise building is huge.The raw material of (surpassing) high-strength prestressed concrete pipe pile is made up of the river sand, the stone that constitute aggregate and the cementitious material cement, levigate silica sand and water, the water reducing agent etc. that are filled in slit between aggregate and play coagulation, each raw material to be stirred into compound by prescription with mixer in process of production, mixture distributor is gone in the pile tube punching block again, pass through processes such as prestressed reinforcement of tensioning, centrifugal forming and stream curing again, promptly produce (surpassing) high-strength prestressed concrete pipe pile.In the centrifugal forming process, can isolate a large amount of surplus slurries,, have a strong impact on, also cause the waste of resource simultaneously if direct discharging not only can cause environment owing to also include cementitious material such as certain cement, levigate silica sand in these surplus slurries.Therefore how to effectively utilize the surplus slurry that produces in (surpassing) high-strength prestressed concrete pipe pile manufacturing process; waste, reduce cost with protection environment, elimination; become each manufacturing enterprise's problem demanding prompt solution, producing high-strength prestressed concrete (more than the C95) pile tube with low glue material has simultaneously become a kind of development trend in the tubular pile industry.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of high-strength prestressed concrete pipe pile, it has made full use of the surplus slurry that produces in process of production, adopts low glue material to produce high-strength prestressed concrete strength and reaches the above pile tube of C95.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of high-strength prestressed concrete pipe pile, it is characterized in that it is to be formed by concrete pouring, the raw material that includes following parts by weight in wherein every cubic meter of concrete: 250 ± 10 parts of cement, 135 ± 10 parts of levigate silica sands, 190 ± 10 parts in surplus slurry, 580 ± 50 parts of medium sands, particle diameter be 0.5～1.5cm 350 ± 50 parts of small stones, 1100 ± 100 parts on rubble head that particle diameter is 1.5～3cm, be equivalent to cement and the water reducing agent of levigate silica sand gross weight umber 0.5～0.75% and an amount of water, the weight concentration 30-40% of cementitious material in the wherein surplus slurry.
The specific area of the levigate silica sand that the present invention adopts is greater than 420.
The fineness modulus of the sandstone that the present invention adopts is 2.5～3.2.
Water reducing agent of the present invention adopts high efficiency water reducing agent, and it can directly be buied from market, is the naphthalene water reducer of HD-5 as the model of spending Wang Qiye and Jiangmen sharp chemical industry of length Co., Ltd to produce.
The invention has the beneficial effects as follows: adopt above-mentioned factory formula, the present invention has following effect: concrete workability is good, satisfies the requirement of operability and centrifugal forming fully; Centrifugal forming is respond well, and cement is fully utilized, and the inner wall smooth laitance layer is thin, and the centrifugal concrete structure is closely knit and reasonable, and presentation quality obviously improves; Surplus slurry composition is greatly improved, and cement factor is few, does not almost have coarse-fine aggregate; Surplus slurry obtains fully rationally utilizing, and normal condition is left and is starched zero waste, thereby obtains good environmental benefit, and has saved the consumption of cement, has reduced cost of production; Tubular pile body concrete material intensity reaches more than the 95Mpa after testing.
The present invention is further described below in conjunction with embodiment.
