The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
The utility model is a kind of empty cylinder upstanding bank, and it comprises that mainly river bottom protection protects beach structure 1, riprap foundation 2, it is characterized in that: riprap foundation 2 end faces are provided with upstanding bank dam body 3, and this upstanding bank dam body 3 comprises a plurality of saturating empty cylinders 10 that are arranged side by side.Saturating empty cylinder 10 comprises top beam 4, foundation ring beam 5, and along many vertical rib beams 6 circumferentially are set, top beam 4, foundation ring beam 5 and vertical rib beam 6 constitute overall structure between top beam 4 and the foundation ring beam 5.This saturating empty cylinder 10 does not have the cartridge type frame construction at the end for uncovered, many vertical rib beams 6 of cylindrical shell upstream face are vertical type fence strip, the cylindrical shell external diameter is 2～10 meters, cylindrical shell thickness is 0.2～0.5 meter, the cylindrical shell depth-width ratio is generally 1.5～0.6, is spaced apart 0.2～0.4 meter between adjacent two vertical rib beams 6.
Saturating empty cylinder planar profile is rounded, oval, polygon or other well-regulated shape.
These saturating empty cylinder both sides are provided with overhanging wing plate 7 respectively, overhanging wing plate 7 is connected with foundation ring beam 5 with top beam 4, join by two pairs of overhanging wing plates 7 (or claim floor) flush joint between the two saturating empty cylinders and form continuous upstanding bank dam body, overhanging wing plate (or floor) is the Eight characters, two fonts or other well-regulated shape, and fill block stone is to reach the requirement of anti-leak-stopping sand in two overhanging wing plate joint cavitys 8.It is sand rib soft raft that the both sides of upstanding bank dam body also are provided with armour rock 3,11, and 12 is the surplus row of sand rib.
Saturating empty cylinder tube internal cavity 9 is if need filling piece stone, and its single weight only needs greater than 20～40kg.
Structure concrete in the enforcement is as follows:
Saturating empty cylinder upstanding bank, its saturating empty cylinder planar profile has circle, ellipse, polygon or other well-regulated shape.Saturating empty cylinder level is stressed with the side direction control that meets water, vertical stressedly control with foundation stress, according to force request, cylindrical shell to Reinforced Concrete Materials can be made the frame construction that uncovered does not have the end, reducing the uplift pressure of cylindrical shell bottom, and increased the comprehensive friction factor of saturating empty cylinder and riprap foundation end face; The cylindrical shell upstream face is arranged to the fence strip, and the wave that disappears is effective; Tube internal cavity 9 filling piece stones form continuous upstanding bank, and its integral dam is good, and stronger capacity of anti-storm is arranged.
The installation of prefabricated empty cylinder and tube internal cavity filling piece stone, can by the loop wheel machine ship directly, Fast Installation puts in place, main equipment utilization rate height, speed of application are fast, construction risk also greatly reduces; The making of saturating empty cylinder and installation quality check difficulty are low, and work for inspection amount waterborne is little, and the dam body construction quality can be controlled preferably.
If saturating empty cylinder upstanding bank is given the functional requirement in early stage and enforcements of go ahead of the rest, after it finishes functional requirement in earlier stage, during structure such as later stage enforcement seawall embankment, be connected also comparatively convenient with it.
Saturating empty cylinder is a plain bars concrete precast construction, strength grade of concrete is generally C30, in the concrete precasting yard, carry out formwork erection, wire-tie, once-cast is finished top beam, foundation ring beam and vertical rib beam concrete, after treating that the cylindrical shell concrete reaches 80%～100% design strength, can work the scene of being transported to that hangs out.
Embodiment 1
Design the submerged breakwater of 4.5 meters of heights of dam, 3.0 meters of top widths.If adopt the saturating empty cylinder upstanding bank layout of this programme, according to tidal level, stormy waves condition, the levee body structure section adopts the saturating empty cylinder filling piece stone upstanding bank of steel bar concrete, top width 3.0～3.5m, saturating empty cylinder external diameter 3.5m, internal diameter 2.9m, high 3.5m, saturating empty cylinder is divided into riprap foundation, and the thick 1.0m of riprap foundation, riprap foundation adopt 10～100kg piece stone, the inside and outside shoulder breadth of riprap foundation is 3.0m, armour rock is adopted on the inside and outside slope of riprap foundation, and grade of side slope is 1: 2.0, saturating empty cylinder Inner stiffener stone.For preventing the beach erosion damage, river bottom protection generally adopts soft raft.
The advantage that this scheme levee body structure reveals: the soft raft lateral length contracts to 47 meters by 58 meters, every linear meter(lin.m.) piece cubic meter of stone amount is contracted to 34 sides by 48 sides, and by the saturating preferably empty cylinder of globality substitute globality relatively poor turn round king's block mask, the dam body capacity of anti-storm greatly improves, saturating empty cylinder can by the loop wheel machine ship directly, Fast Installation puts in place, main equipment utilization rate height, speed of application are fast, and construction risk also greatly reduces, but the reduction of erection time 30%.
For the ease of more relevant index, provide the submerged breakwater material index comparison sheet of 4.5 meters of heights of dam, 3.0 meters of top widths below.
