Detailed Description
The utility model is further described below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
As shown in fig. 1 and 2, the present utility model provides an underwater tower crane foundation comprising: concrete lattice columns and composite steel structures;
the concrete lattice column comprises four reinforced concrete columns 1, wherein two reinforced concrete columns 1 are vertically fixed on one underwater bearing platform 6, and the other two reinforced concrete columns 1 are vertically fixed on the adjacent underwater bearing platform 6; the heights of the tops of the reinforced concrete columns 1 are the same.
The combined steel structure comprises two main steel beams 4 and four transverse steel beams 3, wherein the four transverse steel beams 3 are welded between the two parallel main steel beams 4 in parallel, and the main steel beams 4 are detachably connected to the top of the reinforced concrete upright 1.
In the embodiment, a reinforced concrete column 1 with a concrete mark C30 and a section of 70cm is poured on a water bearing platform 6, and an M48 anchor bolt 2 is embedded in the upper part of the reinforced concrete column 1.
In this embodiment, the main steel beam 4 is a double-spliced HN500×200 steel member, the transverse steel beam 3 is a single-spliced HN500×200 steel member, and the main steel beam 4 and the transverse steel beam 3 are welded together.
The concrete lattice column and the combined steel structure are anchored through the pressing beam 5 with the steel model HN of 500 x 200 and the M48 anchor bolt 2, so that the steel structure beam and the reinforced concrete upright column are detachably connected, and the steel structure beam and the reinforced concrete upright column can be recycled in the later period, and have better economic benefit.
The height of the reinforced concrete lattice column 1 is determined according to the elevation of the underwater bearing platform, and the elevation of the reinforced concrete lattice column is not lower than the elevation of the normal water level, so that the underwater tower crane foundation can be prevented from being immersed in water to the greatest extent, and the safety inspection of the tower crane foundation is facilitated.
The utility model innovatively utilizes the bearing capacity of the existing bearing platform, designs the lattice column type steel structure tower crane foundation, does not need to drive pile foundations such as steel pipe piles, tubular piles or cast-in-place piles, and the like, works such as platform erection or slurry treatment and the like of construction of the underwater pile foundation, utilizes the bearing capacity of the main pier bearing platform, directly constructs a tower crane concrete column foundation in a main pier bearing platform steel sheet pile cofferdam, and then directly hoists a steel structure beam foundation.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model, and such modifications and variations should also be regarded as being within the scope of the utility model.
