A method of lifting a structure includes extending a pipe so as to have one end opening to a lens in the earth, connecting a pump to the pipe, and pumping a grout material through the pipe and into the lens so as to cause a strata of the earth above the lens to heave upwardly and to cause the structure to move upwardly. The grout is solidified in the lens. The pipe is removed after the step of pumping. The grout is a low mobility cement grout. A location of the lens nearest to the structure is determined prior to the step of extending the pipe.

The present invention discloses a brick, comprising a brick body, which comprises at least one slot position for connecting a column, and a method for using the bricks to build dikes in water, including the following steps: (1) drilling a plurality of pile holes at water bottom; (2) casting concrete into each of the pile holes to form concrete columns; (3) stacking up a number of the bricks along the concrete columns and having them tightly connected to form a wall; (4) filling the clearances between the concrete columns and the bricks with mortar. The bricks and dike building method provided by the present invention are suitable for direct over-water dike building, the construction is fast and the dikes built are firm and stable, have superior waterproof function and can effectively prevent the impact of currents, winds and waves.

A device and method for anchoring a raceway mounting of a seabed-to-surface facility. The apparatus having a rigid structure immersed in a subsurface by floats and anchored to the sea bottom by tension legs, the device suitable for supporting troughs in a bottom-to-surface connection installation, having a plurality of flexible lines extending to the sea bottom, the flexible lines being supported by the troughs, the trough support structured is connected to a base resting on and/or anchored to the bottom of the sea by a plurality of n tension legs tensioned in parallel, by the float, n being not less than six, each of a plurality of p tension legs from the n tension legs, where p is not less than (n2) being connected at one of its ends to a distance-varying device secured to the base or to the support structure, the distance-varying device suitable for varying the distance between the support structure and the base.
