Prestressed concrete high-strength anti-corrosion pipe pile and production method thereof
The invention provides a prestressed concrete high-strength anti-corrosion pipe pile. The anti-corrosion pipe pile comprises a pile body and end plates, the two end plates are symmetrically arranged at the two ends of the pile body, a reinforcement cage is arranged in the pile body, and each end plate comprises a connecting plate and a reinforcing pipe sleeve. The end plates which are designed ina split assembly mode are adopted, so that the production and machining process is simpler and more convenient. The reinforcing pipe sleeve welded in the groove can prevent the connecting plate from being deformed and damaged in the pile sinking process through the limiting and supporting effects of the reinforcing pipe sleeve on the connecting plate. In addition, the reinforcing pipe sleeve can increase the contact area between the connecting plate and the pile body, and therefore connection between the end plates and the pile body is firmer. The concrete with a water-cement ratio of 0.28-0.29 is concrete between dry hard concrete and plastic concrete, and due to the fact that the water-cement ratio is very low, the concrete is very low in permeability, excellent in corrosion resistance and high in strength.
本发明提出的一种预应力混凝土高强度防腐管桩，包括桩体和端板，两个所述端板呈对称式设置在桩体的两端上，所述桩体内设有钢筋骨架，所述端板包括连接板和加固管套。本发明采用呈分体式组装设计的端板，使得生产和加工工艺更为简单方便，且焊接在凹槽内的加固管套，能够通过其对连接板的限位和支撑作用，预防连接板在沉桩过程中变形损坏，另外，加固管套能够增加连接板与桩体之间的接触面积，从而使得端板与桩体之间的连接更为的牢固，且水灰比在0.28‑0.29之间的混凝土是一种介于干硬性混凝土和塑性混凝土之间的混凝土，由于水灰比很低，因此此种混凝土的渗透性很低，防腐性能优异，具有高强度。
