Background

The site selection of large coastal engineering faces the difficulties of wide coastal beach, poor geological conditions and the like, and if a permanent wharf with high cost is built for the construction of large engineering, the waste is huge although the construction is necessary. In 2004, to accelerate the construction of the fujiangningde tang power plant, a pontoon trestle system used for a short period of time was rapidly constructed, the investment cost was low, and since the pontoon trestle system could not survive under the sea condition of more than 3 th level, the experience could only be repeated in naturally covered waters, but could not be replicated in open sea areas. In order to meet the requirement of coastal large-scale engineering construction, a temporary wharf long trestle system which can be quickly constructed and can survive under the condition of high sea is needed, and the temporary wharf long trestle system is convenient to switch to use after a task is completed.

Disclosure of Invention

The technical scheme is as follows: in order to achieve the purpose, the caisson wharf long trestle system capable of rapidly constructing survival in high sea conditions adopts the following technical scheme.

A caisson wharf long trestle system capable of rapidly constructing survival under high sea conditions comprises a caisson wharf, an overhead trestle, a gravity type breakwater and a floating trestle. The caisson wharf is formed by filling the wharf box body with silt and sinking to the bottom, and the overhead trestle is formed by lifting the 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 caisson wharf.

The caisson wharf comprises a wharf platform, a support and a bottom cabin, wherein the wharf platform is located at the top, the bottom cabin is located at the bottom and is divided into a plurality of bottom cabin chambers, a pipeline is communicated with the top surface of the wharf platform, the support is located in the middle, and the bottom cabin is connected with the wharf platform. After the wharf box body is transported in place by floating, silt is injected into the bottom cabin, and the wharf box body sinks to sit at the bottom to form a caisson wharf.

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 a caisson wharf, and the other end of the elevated trestle is connected with a gravity breakwater.

A caisson wharf long trestle system capable of rapidly constructing survival under high sea conditions 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, filling silt and seawater into the breakwater box units, enabling the breakwater box bodies to sit at the bottom and enabling the top surfaces to be higher than the water surface, and forming 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 wharf box body to a mounting point, filling silt into the bottom cabin after positioning, and adjusting the posture of the wharf box body by controlling the amount of the filled silt in the bottom cabin so that the wharf caisson sinks uniformly, wherein the wharf box body becomes a caisson wharf after sitting at the bottom;

(4) floating a plurality of elevated trestle units to a designed position, 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 a gravity breakwater, and connecting the other end of the elevated trestle unit with a caisson wharf platform to form an 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 of the long trestle section is connected with the caisson 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 caisson wharf is formed by filling silt and sinking after the wharf box body is transported in place by floating, and the operation speed is high. The wharf platform of the caisson wharf is higher than the water surface, and water permeates from the upper part of the bottom cabin to the lower part of the wharf platform, so that wave reflection at the front edge of the wharf is avoided, ships can stop conveniently, and the survival ability in the waves is improved. The elevated trestle is formed by lowering pile legs of a floating platform and lifting the platform above the water surface, on one hand, the elevated trestle can be quickly constructed, and on the other hand, the elevated trestle can survive under high sea conditions. 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 breakwater is arranged in the shallow water area, even in severe sea conditions, the kinetic energy of waves reaching the shallow water area is greatly reduced under the wave dissipation effect of the long gentle slope seabed, and the gravity breakwater can block the waves from directly propagating to the shore, so that the floating trestle in the shallow water area on the shore can be protected. When the trestle platform needs to be transferred for use, the trestle platform is lowered to float on the water surface by using the lifting mechanism, and the trestle platform can be transported in a floating manner after the pile legs are lifted by using buoyancy; and (4) discharging silt in the caisson wharf and the gravity breakwater, and recovering the floating state and then carrying out floating transportation.

The invention has the beneficial effects that: the caisson wharf is formed by filling silt and sinking after the wharf box body is transported in place in a floating mode, and the elevated trestle is formed by lowering pile legs of the floating platform and lifting the platform above the water surface. 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 type breakwater is formed by quickly filling silt in a breakwater box body and then sitting at the bottom, so that the floating trestle in a shallow water area can be protected on one hand, and the gravity type breakwater can be used as a transition between an elevated trestle and the floating trestle on the other hand.
