Problems solved by technology

During the riprap leveling construction of the foundation bed, the hull platform needs to be lifted to the construction height. Since the hull platform floating on the sea / river surface is greatly affected by natural conditions such as waves and silt, it is difficult to ensure the laying accuracy and construction of the foundation bed. Stability and safety of the hull platform during the process

Embodiment Construction

[0025] 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.

[0026] Such as figure 1 , the present invention is a kind of diagonal ballast lifting method for leveling ship, comprising the following steps:

[0027] S1. Lower the legs 2 on the four corners of the hull platform 1 into the mud at the same time, and continue to apply load to the legs 2 until the legs are stable;

[0028] S2, lifting the hull platform 1 until the hull platform 1 leaves the water surface 3;

[0029] S3, using diagonal step-by-step ballasting to stabilize the legs 2 on the four corners of the hull platform 1;

[0030] S4. Lift the hull platform 1 to the construction height position.

[0031] In this embodiment, the leveling boat is lifted by a lifting d...

Abstract

The invention relates to an underwater foundation bed riprapping and leveling technology, and discloses a diagonally ballasting and lifting method for a leveling ship. The method comprises the following steps of: S1, putting pile legs on four corners of a ship body platform into mud, and continuously applying load to the pile legs until being stable; S2, lifting the ship body platform until leaving the water; S3, stabilizing the pile legs on the four corners of the ship body platform by using the diagonally and stepwise riprapping; S4, lifting the ship body platform to a construction height position. An air gap height for lifting the ship body platform until leaving the water in the step S2 may reach 0.5-1.5m. The diagonally ballasting and lifting method for the leveling ship is high in work efficiency, and can save time and ensure the stability and safety in the process of lifting the ship body platform and the paving accuracy of the foundation bed.

Description

technical field [0001] The invention relates to a stone riprap leveling technology for an underwater foundation bed, in particular to a diagonal ballast lifting method for a leveling ship. Background technique [0002] During the laying and leveling construction of the offshore (Hanoi) immersed tube tunnel foundation, before the immersed tube is installed, it is necessary to carry out riprap leveling in the excavated foundation groove, and then float the prefabricated immersed tube to the upper part of the foundation bed and sink it Install. The riprap foundation bed is used to replace the original soft soil layer to improve the bearing capacity of the foundation, so that the load from the upper structure can be evenly transmitted to the foundation to meet the requirements of deformation and stability, and make full use of its water permeability to reduce The water level difference between the front and back of the building avoids seepage and protects the foundation from wa...
