Reinforced concrete pile foundation with variable section and pile sinking method thereof
The invention discloses a reinforced concrete pile foundation with the variable section and a pile sinking method thereof. Reinforced concrete piles with the variable sections are divided into prefabricated piles and cast-in-place piles. The prefabricated piles comprise a T-shaped prefabricated pile and a trapezoidal prefabricated pile. The prefabricated piles with the variable sections are prestressed reinforced concrete prefabricated piles. The T-shaped prefabricated pile is composed of a pile end with the enlarged section and a pile body with the equal diameter and the small section, and the axial profile is in a T shape. The enlarged pile end is connected with an upper joint pile with the section of the same size, and thus a variable section pile foundation with the large upper joint pile section and the small lower joint pile section is formed. The section of one end of the trapezoidal prefabricated pile is large in size, the section of the other end of the trapezoidal prefabricated pile is small in size, the diameter is varied gradually, and the axial profile of a pile body is in a trapezoid shape. The cast-in-place piles with the variable sections are reinforced concrete piles cast in place after hole forming, and are in a big end up step shape with different diameters. The reinforced concrete pile foundation has social benefits of being green, environmentally friendly,safe and reliable, meanwhile, the manufacturing cost can be reduced, the working period is shortened, and the reinforced concrete pile foundation has great economy value.
本发明公开了变截面的钢筋混凝土桩基及其沉桩方法，变截面的钢筋混凝土桩分为预制桩和灌注桩，预制桩有T形预制桩和梯形预制桩两种。变截面预制桩为预应力钢筋混凝土预制桩；T形预制桩由扩大截面的桩端和等直径小截面的桩身组成，轴向剖面呈T形；扩大的桩端与具有相同尺寸截面的上节桩相连接，组成上节桩截面大下节桩截面小的变截面桩基；梯形预制桩是一端截面尺寸大，另一端截面尺寸小，直径是渐变的，桩身轴向剖面呈梯形；变截面的灌注桩是成孔后现浇的钢筋混凝土桩，呈上大下小不同直径的阶梯状。该专利具有绿色、环保和安全可靠的社会效益，同时能降低造价和缩短工期，具有重大的经济价值。
