Immersed tube flat-bottom valve macadam replacement construction method and flat-bottom valve device
The invention discloses an immersed tube flat-bottom valve macadam replacement construction method and a flat-bottom valve device. The immersed tube flat-bottom valve macadam replacement construction method includes the following steps: A, the bottom of the valve device is placed in place, the valve device is placed in a construction area, and a bottom opening of a steel sleeve is arranged on the valve device in a sitting mode; B, a vibratory hammer is used for tube immersing, wherein the steel sleeve is gradually extruded into soil through the vibratory hammer; C, the steel sleeve is filled with stone, and after the steel sleeve is immersed in place, the steel sleeve is filled with macadam; D, the bottom of the valve device is pulled open to pull out the steel sleeve. By means of the immersed tube flat-bottom valve macadam replacement construction method and the flat-bottom valve device, consistency of the hardness of the upper portion and the hardness of the lower portion in construction can be guaranteed, and a foundation is more compact.
