Description
Technical field
The invention belongs to port works field, relate in particular to a kind of box-type suction foundation sluice structure and enclose the construction method that low bank between fields closes up mouth.
Background technology
Enclose in low bank between fields work progress big-and-middle-sized, conventionally need section construction, finally close up.Owing to holding together, mouthful place's flow rate of water flow is larger, more serious to washing away of mud face herein, ground thereby be damaged, depression of bearing force, occurs that low bank between fields body sinks, the situation of becoming silted up is squeezed in both sides, to cause closing up after cutout, and close up mouthful place's low bank between fields body and sink, water is crossed on road surface, add that the low bank between fields body seepage flow, the Piping phenomenon that have just filled are more serious, close up mouth and be very likely rushed to open.Close up mouth is also emphasis, the difficult task of enclosing in low bank between fields work progress always, directly has influence on cost, duration and the quality of engineering, has very important effect.At present the conventional measure of closing up is that oversize rock material is filled at low bank between fields body and is subject to current directly to wash away side, and slightly thin debris from demolition fills at opposite side, and pursuing-tide position constructs, to reduce the loss of current scour.The defect of this measure is to use a large amount of oversize rock materials, and construction cost is high, technique is loaded down with trivial details, and restricted application.
In addition, day by day serious along with the deficient problem of freshwater resources, desalinization also will played the part of more and more important role in human lives, large-scale Seawater Desalination Project also will obtain applying more and more widely, and water intaking lock is to ensure water intaking quality and the safe important leverage structure of water intaking, in Seawater Desalination Project, there is important effect.At present conventional water intaking lock adopt below the form of structure of pile foundation is set, the defect of this kind of form of structure is that complicated construction technique, cost are high, less stable, the flat weight bearing power of pile foundation water resistant is poor, due to tidal action, balancing reservoir and outer saline waters are inconsistent at water intaking lock both sides water level, put on water intaking lock and pass to pile foundation poor mineralization pressure, very easily causing pile foundation destruction.
Number of patent application: 200720099572.5 disclose a kind of removable cylindrical infrastructure part of cylinder of stake with ribbing, it comprises 3 to 6 steel wall cylinders without tail band top board, adjacent cylinders body is arranged in triangle or quadrangle, between adjacent cylinders body, connect by vertical steel plate, on the top board of each cylinder, be provided with the through hole of belt switch, the vertical rib stake of steel is set on the barrel of each cylinder, rib stake lower end is sharp cone distal, fill concrete or cement mortar in rib stake. above-mentioned patent discloses a kind of case cylindrical foundation form of structure, but its defect is the processing technology thereof complexity of case barrel structure, construct loaded down with trivial details.Number of patent application: 200420029467.0 disclose a kind of removable steel reinforced concrete box-type suction foundation vertical arc diaphragm wall breakwater structure, it connects into overall top wave wall on it and forms by being inserted into box-type suction foundation in seabed soil and being located with it; Box-type suction foundation comprises the steel cylinder by four equal diameters, equal altitudes, bottomless, barrel inner side or the vertical floor of arranged outside, the cuboid connecting and composing by being located at cylinder junction plate between any two; The monoblock concrete material cover plate of laying in this four cylinders cuboid upper surface; In the top blind flange of the middle chamber surrounding at each cylinder and four cylinders, offer can switch through hole; Wave wall be by least two sections of equal diameters, etc. the upright circular arc concrete material wall section of arc length connect into continuous " S " type body of wall.The present invention is applicable to weak soil sea bed ground, and little, the simple installation of construction volume on constitution water, compliance and anti-wave ability to the depth of water are strong, and engineering cost is relatively low.Above-mentioned patent discloses a kind of case cylindrical foundation form of structure and the application in breakwater engineering thereof, but its deficiency is not propose building or mounting method of superstructure.
Summary of the invention
