Description

Hillside plot piece
Technical field
The present invention relates to the hillside plot piece of the optimization use of traditional gravity hydro-structure.
Background technology
The form of structure of marine traffic engineering mainly comprises gravity, high stake formula, and wherein gravity structure, short construction period low with its good endurance, cost, the advantage such as simple, be widely adopted.
Water conservancy project gravity structure mainly contains the forms such as square, jackstone sloping breakwater, caisson and packed sand, according to the depth of water, the hydrology, geology and the instructions for use on engineering ground, and can be by determining rational structure than choosing.
Along with the exploitation of ocean, started the upsurge of shoal regional construction man-made island at sea both at home and abroad.Wall current form of structure in island mainly adopts gravity structure, comprises the form that vertical type bulkhead wall (caisson or square) is combined with jackstone sloping breakwater; Need that mole is set simultaneously subregion is screened, comprehensively essential according to the depth of water, resource, fresh water (FW) equality aspect, adopt caisson vertical type or jackstone sloping breakwater structure more
Tradition gravity hydro-structure inferior position in the offshore artificial island construction of (comprising island body and shielding system) is more and more obvious, is mainly described below:
1, the upright bulkhead wall structure of caisson
1. along with the depth of water strengthens, hydrologic condition worsens, the size of caisson is increasing, and concrete amount, the cost of linear meter(lin.m.) bulkhead wall are multiplied;
2. precast fortune equipment enlarging, complex process;
3. bearing capacity of foundation soil requirement is high, has to take carry out technical measures and meets the demands, and based process cost is larger;
4. wave, flow through after upright wall reflection, basis before caisson is caused and is washed away, Anti-scouring structure need be set.
5. caisset needs cast-in-place superstructure, connects high to design elevation.
2, jackstone sloping breakwater structure
1. along with the depth of water strengthens, hydrologic condition worsens, building stones consumption becomes geometric progression increase, and (the man-made island sloping breakwater structure island wall building stones consumption of ten thousand mu of levels often surpasses 5,000 ten thousand m 3), resource consumption is huge, and the resource in economic zone can not meet supply conventionally, need exploit in the larger context, transport building stones, and cost sharply strengthens;
2. from levee crown, put slope to the horizontal length of original ground and guarantee the stable back-pressure rib body of levee body, the length of protection-apron, making man-made island take oceanic area very large, can account for 50%~80% of requisition marine site by usable floor area, causing the economic benefit of project on the low side;
3. the ground surface protection structure of the domatic wave resistance of sloping breakwater, stream, arranges specification piece stone bed course conventionally, lays artificial armour, the enormous amount of mask piece, and cost is larger.
4. inner slope inverted filter quality requirement is high, once destroy, has a strong impact on the safety that forms land-based area, repairs difficulty.
Summary of the invention
The present invention overcomes above-mentioned defect, and the inferior position for traditional gravity hydro-structure in offshore artificial island (comprising island body and shielding system) is built has been invented main member-hillside plot piece of optimizing.
The technical scheme of hillside plot piece of the present invention is such: it comprises base plate, and upright wall is set in the middle of base plate, and upright wall both sides arrange the bottom ballast compartment being surrounded by outer partition panel and interior partition panel.
Optimally, ballast compartment in bottom arranges deep floor in the surrounding of upright wall.
Upright wall in the technical program, its effect is before and after seawater, to separate, height can directly reach setting absolute altitude, must cast-in-place superstructure.
Preferably, the bottom ballast compartment arranging before and after upright wall, the weight of the backfill of the deadweight of rear compartment, the filler in storehouse and compartment top, can produce skid resistance, guarantee structure Against Sliding Stability, the compartment deadweight in bulkhead wall the place ahead, the filler deadweight in storehouse, not only produce skid resistance and guarantee structure Against Sliding Stability, can also increase overturning or slip resistance analysis moment and guarantee structure stability against over turning, can also play protection against erosion effect.
Effect of the present invention (with reference to Fig. 3, Fig. 4):
1. guaranteeing, under constitutionally stable prerequisite, caisson section to be simplified to upright wall, play the effect of upright bulkhead wall, greatly reduced linear meter(lin.m.) bulkhead wall concrete amount, reduced cost, raising progress;
2. linear meter(lin.m.) member dead weight reduces, and can according to existing equipment, set block length flexibly;
3. the setting of bottom ballast compartment, has optimized the distribution of foundation pressure, and bearing capacity of foundation soil requires to decrease, based process cost;
4. bottom ballast compartment and backfill building stones, played protection against erosion effect;
5. greatly improve the In-commission Rate in requisition marine site, improve Project Economy Benefit.
6. reduced the great demand of sloping breakwater structure to building stones, economized on resources, reduced costs;
7. do not need the ground surface protection structure of sloping breakwater structure, greatly reduced the cost of project, saved loaded down with trivial details operation, progress significantly improves.
8. after the joint treatment of adjacent hillside plot piece is improved, inverted filter structure can be simplified or cancel, and reduces Project Cost, raising progress.
