The sloping caisson breakwater with the supporting pile and the downward-inserted box is characterized in that a plurality of supporting pile holes are formed in a sloping caisson body; a supporting pile for supporting the sloping caisson body is arranged in each supporting pile hole and passes through the underwater soft soil layer to be inserted into an underwater bearing layer; the downwards-inserted box which is inserted below the underwater mud face is arranged on the lower surface of a bottom plate of the sloping caisson body, wherein the downwards-inserted box is an inverted quadrate box body of which the lower part is opened. According to the sloping caisson breakwater with the supporting pile and the downward-inserted box, the supporting piles and the downwards-inserted box improve the loading capacity of the sloping caisson in the vertical and horizontal directions, so that the caisson cannot be settled or deformed, the use requirement is met, the work of treating the caisson foundation is avoided, the cost of foundation treatment is decreased, and the stability of the caisson is improved; the building materials are decreased, the construction efficiency is high, the manufacturing cost is low, the investment is small, the construction cycle is short, and therefore, the caisson is particularly suitably constructed on a soft soil foundation.
Description
Technical field
The present invention relates to marine structure field.
Background technology
Mole is the important hydraulic structure in harbour, for defending wave to the invasion and attack of harbour region, ensures that there is stable waters at harbour, is convenient to boats and ships and stops mooring, carry out cargo handling operation and upper and lower passenger smoothly.Along with the development of World Economics and the growth of trade, excellent bay is developed totally, and new port has to develop to the marine site of bad environments, in the depth of water the wave is high, construction harbour, the marine site mole of complicated geology is inevitable trend, build the mole at harbour, cost is high, and investment is large.
For reducing costs, applicant has applied for that application number is 201320547875.4, and name is called the patent of ramp type caisson breakwater.The content of claim mainly, longitudinally ramp type caisson breakwater is formed by a plurality of ramp type caisson body, ramp type caisson body is reinforced concrete box shaped structure, comprise the caisson body horizonal base plate being positioned at bottom, the horizontal vertical wall of a plurality of caisson body, the longitudinal vertical wall of a plurality of caisson body, the top of ramp type caisson body is the caisson body levee crown slope raised by side, side direction mole port, mole sea, the gradient of caisson body levee crown slope is between 1: 3 to 1: 1, and the height of caisson body levee crown slope is 1 to 4 times of wave height.
Ramp type caisson breakwater has the advantage of existing ramp type riprap breakwater, fragmentation is there is in wave on caisson face, slope, major part wave energy is absorbed and is dissipated in the traveling process of slope, reflexion of wave is little, and stability is high, and the mole section that turn avoid existing ramp type riprap breakwater is large, mole jackstone material usage is many, when particularly the depth of water is larger, the increase mole jackstone material with the depth of water can greatly increase, and makes the shortcoming that cost increases.
Ramp type caisson breakwater adopts reinforced concrete caisson to do levee body, concrete service efficiency high strength is good, the concrete caisson of box-shaped has higher bulk strength, compared with sloping breakwater, constructional materials consumption is less, concrete caisson is overall by land to be manufactured, easy construction, low cost of manufacture.
For making ramp type caisson breakwater have higher stability at sea, need ramp type caisson to have larger quality, larger mass loading can make again mole produce sedimentation and distortion, and ramp type caisson breakwater must have firm and that bearing capacity is high basis to support.In the coastal seabed mostly being weak soil basis, weak soil basis is sposh shape, and supporting capacity is extremely low, and mole is built on weak soil basis, first will dig up mud, then changes back-up sand or stone, makes firm basis, and Foundation Design amount is large, and cost is high.
The basic cost of ramp type caisson breakwater structure is high, investment is large, can not meet the needs of economic development and construction.It is just more difficult that neritic province domain particularly on weak soil basis builds mole, and the handling expenses of labour material on weak soil basis, cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ramp type caisson breakwater with supporting pile and lower subrack, further improves ramp type caisson breakwater.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind ofly longitudinally form the ramp type caisson breakwater with supporting pile and lower subrack by a plurality of ramp type caisson body with supporting pile and lower subrack, ramp type caisson body is reinforced concrete box shaped structure, the top of ramp type caisson body is the caisson body levee crown slope raised by side, side direction mole port, mole sea, the extra large side of ramp type caisson body and the inwall of port side box wall there is a plurality of support stake holes, supporting stake holes is the square through hole be made up of the longitudinal wall of parallel bilayer and perpendicular transverse wall, support the supporting pile having in stake holes and support ramp type caisson body, supporting pile is inserted in the bearing layer in seabed through seabed Soft Soil Layer, support between stake holes and supporting pile and leave gap, in gap, supporting pile and ramp type caisson body are linked fixing link fixing concrete by filling, the supporting pile plugging block of shutoff supporting pile is arranged at the top supporting stake holes, the lower subrack inserted under mud face, seabed is had below the base plate of ramp type caisson body, lower subrack is the square box of lower openings back-off, casing surrounding has the lower subrack cabinet exterior of vertical direction, a plurality of are had to increase the lower subrack reinforcing rib wall of the vertical direction of lower subrack casing intensity and rigidity in casing.
Described supporting pile is reinforced concrete pile that is circular or square-section.
Described single a plurality of support stake holes and supporting pile are positioned in the vertical direction on the port side box wall inwall of ramp type caisson body.
In vertical direction on the port side box wall inwall that described double support stake holes and supporting pile are positioned at ramp type caisson body and on extra large side box wall inwall.
