The technical scheme is as follows: in order to achieve the purpose, the invention provides a high pile wharf long trestle system capable of rapidly constructing high sea condition survival, which adopts the following technical scheme.

A high pile wharf long trestle system capable of rapidly constructing high sea survival conditions comprises a high pile wharf, an overhead trestle, a gravity breakwater and a floating trestle. The high-pile wharf and the elevated trestle are formed by lifting a floating platform. The gravity type breakwater is formed by a plurality of breakwater box body units filled with silt and then sitting at the bottom, and the top surface of the breakwater box body unit after the sitting at the bottom is higher than the water surface. One end of the floating trestle is connected with a shore, and the other end of the floating trestle is connected with a gravity breakwater; one end of the elevated trestle is connected with a gravity breakwater, and the other end is connected with a high-pile wharf.

The high-pile wharf comprises a floating platform, pile legs and a lifting mechanism, wherein the pile legs vertically penetrate through the floating translation, the lifting mechanism controls the pile legs to lift relative to the floating platform, the pile legs are placed down from the floating platform, and the placed pile legs are inserted into a soil layer to serve as supports to lift the floating platform upwards to the water outlet surface to form the high-pile wharf platform.

The elevated trestle is formed by connecting a plurality of elevated trestle units, each elevated trestle unit comprises a floating platform, pile legs and an elevating mechanism, the pile legs vertically penetrate through the floating translation, the elevating mechanism controls the pile legs to ascend and descend from the floating platform, the pile legs are transferred from the floating platform, the transferred pile legs are inserted into a soil layer to serve as a support to upwards lift the floating platform out of the water to form the elevated trestle, one end of the elevated trestle is connected with an elevated pile wharf, and the other end of the elevated trestle is connected with a gravity breakwater.

A high pile wharf long trestle system capable of rapidly constructing high sea condition survival comprises the following construction methods:

(1) transporting a plurality of breakwater box units to a near shore line where the elevated trestle unit can arrive in a floating mode, and filling silt into the breakwater box units to enable the breakwater box units to sit at the bottom to form the gravity type breakwater;

(2) erecting a floating bridge in a shallow water area from the gravity type breakwater to the shore, wherein one end of the floating bridge is connected with the shore, and the other end of the floating bridge is connected with the gravity type breakwater to form a floating trestle;

(3) floating the high-pile wharf equipment to a erection point, lowering pile legs after positioning, inserting the lowered pile legs into a soil layer to serve as a support, and lifting the water outlet surface of the floating platform upwards by using a lifting mechanism to form a high-pile wharf platform;

(4) floating a plurality of elevated trestle units to a design position between a gravity type breakwater and a high-pile wharf platform, connecting the elevated trestle units into a floating trestle, lowering pile legs, inserting the lowered pile legs into a soil layer as a support, upwards lifting the floating platform out of the water, connecting one end of the elevated trestle unit with the gravity type breakwater, and connecting the other end of the elevated trestle unit with the high-pile wharf to form the elevated trestle; or a plurality of elevated trestle units are transported to the designed position by floating and then are respectively put down with the pile legs, the put-down pile legs are inserted into the soil layer to be used as the support to lift the floating platform upwards to the water outlet surface, the adjacent elevated trestle units are connected to form a long trestle section, one end of the long trestle section is connected with the gravity breakwater, and the other end is connected with the elevated trestle wharf to form the elevated trestle.

The working principle is as follows: because the floating trestle does not have the viability under the condition of the sea condition of more than 3 levels, but the wharf and long trestle system for the open sea area needs to be used for a plurality of months to a plurality of years, is bound to be in the face of adverse sea environment conditions such as high sea conditions and the like, only the fixed wharf and the fixed trestle can be adopted, and the common fixed wharf and fixed trestle have long construction period and high construction cost and cannot be used in a field. The high pile wharf long trestle system is formed by lowering pile legs by a floating platform and lifting the platform above the water surface, so that the high pile wharf long trestle system can be quickly constructed on one hand, and can survive under a high sea condition on the other hand. Because the trestle needs to pass through a shoal, particularly the bearing capacity of a silt beach is weak, the elevated trestle unit has certain draft, can be close to 2.0m, cannot directly reach the shore, and needs to bridge the shore by using a floating trestle, so that a gravity type breakwater is constructed on the same line of the shore where the elevated trestle unit can be transported in a floating manner, on one hand, the floating trestle at the shallow water section on the shore is protected, and on the other hand, the transition between the floating trestle and the elevated trestle is realized. Because the gravity type breakwater is arranged in the shallow water area, even in severe sea conditions, the kinetic energy of waves in the shallow water area is greatly reduced under the wave-dissipating effect of the long gentle slope seabed, the floating body is filled with silt and seawater and then sits at the bottom, the top surface is higher than the water surface, the waves can be prevented from being directly transmitted to the shore, and therefore the floating trestle in the shallow water area on the shore can be protected. When the floating platform needs to be transferred to a field for use, the wharf platform and the trestle platform are lowered to float on the water surface by using the lifting mechanism, and the pile legs can be lifted by using buoyancy and then transported in a floating manner; and (4) discharging silt in the gravity breakwater, and recovering the floating state and then carrying out floating transportation.

The invention has the beneficial effects that: the high pile wharf and the elevated trestle are formed by lowering pile legs from the floating platform and lifting the platform above the water surface, so that the high pile wharf and the elevated trestle can be quickly constructed on one hand, and the other side can survive under the condition of high sea. The floating bridge is used as a trestle bridge of a shoreside shallow water area, and the obstacle of shallow water beaches can be overcome. The gravity breakwater is formed by adopting a floating body to quickly fill silt and then sit at the bottom, so that the floating trestle in a shallow water area can be protected on one hand, and the gravity breakwater can be used as a transition between an overhead trestle and the floating trestle on the other hand.
