Description
Technical Field
The invention relates to reinforcement and anti-scour protection of an artificial island, in particular to a combined pile plate structure for reinforcement and protection of the artificial island and a construction method thereof.
Background
The investment of the country on large-scale infrastructure such as island reefs, ports, navigation channels and the like is more and more intensive, wherein artificial hydraulic reclamation island building is an effective way for expanding the utilization space of the oceans in China, fully utilizing ocean resources and announcing the ownership of the ocean territory.
At present, the main raw material of the artificial reclamation island reef in China is calcium coral sand, the main chemical component of the artificial reclamation island reef is calcium carbonate, the particle structure is loose and porous, and the mechanical property is special. The large-area hydraulic filling coral sand island reef foundation is not uniform in engineering mechanical property, is easy to break under large load impact, and is in severe natural environment, and the surface soil body of the island foundation is seriously washed and eroded by wave flow, so that the overall safety of the artificial island reef is seriously threatened. Therefore, foundation reinforcement and scouring protection of the island reef manually blown and filled are unnecessary to be reduced.
At present, the reinforcement of the artificial island foundation still continues to use a rolling method for reinforcing the land foundation, namely, special heavy engineering mechanical equipment is adopted to repeatedly and continuously roll soil, the sizes of grains of coral sand are mutually filled after rolling, the grains are fully embedded and occluded, and the effective stress of the foundation is obviously improved. However, the method cannot be used for underwater construction and cannot meet the requirement of reinforcing the underwater island foundation.
In addition, the artificial island foundation and the side slope scour protection mostly adopt a method of constructing a breakwater by throwing prefabricated breakwater blocks. By utilizing the irregular structure of the wave-proof block, the action strength of wave current on the island foundation and the side slope is reduced, and the scouring erosion of the surface soil body is reduced. But the method has high construction cost, poor adaptability to tidal current water level, easy washout and flowing away of the wave-proof block and short protection period.
Chinese patent application with publication number CN205712073U discloses a sea wave-proof steel sheet pile for marine artificial island, which is composed of a circular main pipe (1) and two side connecting fasteners (2) connected with adjacent steel sheet piles, wherein the connecting fastener on one side is a small round pipe with a longitudinal opening, the connecting fastener on the other side is a T-shaped structural member, the vertical side of the T-shaped structural member is used for being inserted into the opening of the small round pipe on the adjacent steel sheet pile, and the upper horizontal side of the T-shaped structural member is used for being inserted into the small round pipe on the adjacent steel sheet pile to prevent the separation of the vertical side and the small round pipe so as to realize the connection of the adjacent steel sheet piles. However, the connecting part of the adjacent steel sheet piles is weak in structural strength, easy to damage under the long-term action of ocean currents, long in combination length of the T-shaped structural part and the small circular pipe in the vertical direction and difficult to control the vertical degree during construction.
Chinese patent application publication No. CN1963042A discloses a hydraulic inserting plate and a method for using the same, which comprises a reinforced concrete pile plate and a water pipe vertically installed in the reinforced concrete pile plate, a water distribution pipe transversely installed at the bottom and communicated with the water pipe, a slide way installed at one side, a slide plate installed at the other side, a lifting ring installed at the top and a pre-buried steel bar, and further comprises vertical water-separating channels installed on the reinforced concrete pile plate, the slide way and two sides of the slide plate. The method can be used for dam engineering, port and channel engineering, hydraulic engineering such as artificial islands in water, road traffic bridges, water gates, culverts, water delivery channels and the like, and reinforced concrete underground integral engineering. However, the hydraulic inserting plate is adopted, and the defects of high construction difficulty, difficulty in entering a bed body and the like exist in the construction process.
Therefore, the problems of reinforcing and protecting the artificial reef in the prior art need to be solved.
