Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] It should be noted that a method of improving the levelness of dredging and filling according to the present invention is based on floating temporary cofferdams, wherein the floating temporary cofferdams include floating breakwaters, inner weirs and reverse flow weirs, floating The vertical breakwater and the anti-reflux weir are arranged vertically to form an L-shaped fence. The inner barrier weir is installed outside the anti-reflux weir in parallel with the floating breakwater, and the anti-reflux weir is equipped with a blow-fill pipe, which passes through the anti-reflux weir. Extending to one side of the floating breakwater, and the floating breakwater is spli...

Abstract

The invention provides a method for improving the hydraulic fill flatness. The method comprises the following steps that hydraulic fill pipes are laid in areas to be hydraulic-filled, and an energy dissipater is installed and arranged at the tail end of each hydraulic fill pipe; when each hydraulic fill pipe is in a non-oscillating state, the distance between each hydraulic fill pipe head and a boundary point of coverage of the corresponding hydraulic fill pipe head, the angle between the connecting line between each hydraulic fill pipe head and the boundary point of the coverage of the corresponding hydraulic fill pipe head and the axis of the corresponding hydraulic fill pipe head and the perpendicular distance between the axis of each hydraulic fill pipe head and a corresponding temporary cofferdam are acquired, and the oscillating angle of each hydraulic fill pipe is acquired through calculation; based on the oscillating angles of the hydraulic fill pipes, filling is conducted on ahydraulic fill area. According to the method for improving the hydraulic fill flatness, through additional arrangement of the energy dissipaters on the hydraulic fill pipes, the dispersal area of each hydraulic fill pipe is improved, impulsive force of each pipe orifice is reduced, and then the purposes of accurately controlling the elevation of the hydraulic fill area and improving the hydraulicfill flatness are achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a method for improving the levelness of dredging and filling. Background technique [0002] With the continuous deepening of my country's reform and opening up and the rapid development of social economy, in densely populated and economically developed coastal areas, especially coastal ports, the demand for land is increasing, and reclamation projects are increasing, and dredging reclamation is gradually being widely used. among these projects. Now more and more dredging reclamation technologies are being used for land reclamation, port area development, and site construction. After dredging, it is necessary to carry out a series of construction projects such as post-loading and preloading on the sand surface of dredging, so the flatness of dredging plays a vital role in the later construction. [0003] There are generally hydraulic methods and mechanical l...
