Platform and port and pier etc., its structural shape is mainly cylindrical shape or box-cylinder type structure, and top is provided with cover, surrounding be circular or
Square stack shell, bottom opening.Ocean engineering bucket foundation generally uses marine negative pressure sinker technique or malleation sinker technique at present
Carry out location is installed, the limitation sunk due to negative pressure and malleation, often occur to wait severe sea condition to draw owing to marine stormy waves is bigger
The bucket foundation sent out installs the situation terminating or cannot be carried out, and causes construction delay, installation cost to raise.
Summary of the invention
Present invention aim at providing a kind of bucket foundation that can sink and using method thereof with explosion, this device has peace
The advantage that the dress cycle is short, installation cost is low.
The present invention is realized by the following technical programs: a kind of bucket foundation that can sink with explosion, including steel
Matter part, concrete parts and explosive installing hole, described steel part is cylindrical structural, and described concrete parts is arranged
In the bottom of steel part, concrete section is divided into the cylindrical structural bottomless without top, and described explosive installing hole is uniformly arranged on
Concrete parts bottom.
And, thickness is steel section diameter 8%～the 15% of described steel outer wall, described concrete section
The thickness divided is identical with the thickness of steel part.
And, the outer wall height of described concrete parts is the 20%～30% of steel outer wall height.
And, described concrete parts and steel part concentric.
And, the 15%～85% of a diameter of concrete parts thickness of described explosive installing hole, explosive installing hole
The 20%～80% of the outer wall height of a length of concrete parts, the quantity of explosive installing hole is 4～100.
The using method of a kind of bucket foundation that can sink with explosion, including procedure below: determine that device is pacified the most successively
Load soil parameters in the range of heavy influence depth, install needed for explosion number of times and the explosive amount of filling out, required explosive installing hole
Diameter and length and quantity, steel segment thickness, the distance of adjacent explosive installing hole, formulate blasting scheme；Then basis
Steel segment thickness and explosive installing hole length, quantity and spacing carry out land fabrication, prefabricated complete after carry out dynamite charge work
Make, and according to the blasting scheme formulated, explosive installing hole number consecutively is grouped；Finally device is consigned to infield, and under
Put to sea bed, after device is stable, ignites first group of explosive according to the blasting scheme formulated, make device rely on after explosion certainly
Heavily sink, after sinking and stablizing, ignite second group of explosive again, make device again rely on deadweight to sink after explosion, repeat this behaviour
Make, until explosive has all been ignited or device sinks down into designated depth.
And, in the range of device installation sinking influence depth, soil parameters is according to the geologic prospect report of Attention problems position
Announcement determines；The diameter of explosive installing hole of explosion number of times, the explosive amount of filling out and required setting needed for installing, length sum
Amount determines according to soil parameters；The steel segment thickness of device and the distance of adjacent explosive installing hole are produced according to single hole explosive blasting
Raw energy determines.
Present invention have an advantage that compared with prior art, the present invention can realize utilizing the principle of directional blasting by sea
Bucket foundation lays sinking, and in blasting process, the porosity moment between sandy soil increases, and the resistance moment of sandy soil subtracts simultaneously
Little, barrel-shaped foundation sinking, affected bigger when thus avoiding employing negative pressure sinker technique or malleation sinker technique by sea situation
Defect, during whole installation in realize controllable adjustment, have reduce offshore construction cost, shorten the offshore construction time spy
Point.

Detailed description of the invention
Below in conjunction with preferred embodiment, to the detailed description of the invention provided according to the present invention, details are as follows:
Embodiment 1
As it is shown in figure 1, a kind of bucket foundation that can sink with explosion, including steel part 1, concrete parts 2 and explosive
Installing hole 3, described steel part is cylindrical structural, and described concrete parts is arranged on the bottom of steel part, coagulation
Soil part is the cylindrical structural bottomless without top, and described explosive installing hole is uniformly arranged on concrete parts bottom.Steel portion
The exceptionally thickness of wall is the 10% of steel section diameter, and the thickness of concrete parts is identical with the thickness of steel part.Concrete
Outer wall height is steel outer wall height the 25% of part.Concrete parts and steel part concentric.Explosive installing hole
A diameter of concrete parts thickness 80%, the 80% of the outer wall height of a length of concrete parts of explosive installing hole.Make
With front, carry out simple test in shallow water field, Tianjin Bohai Bay port, determine soil parameters, peace according to this field geological exploration situation
