Abstract

The utility model relates to a load-bearable catamaran with an overhang board, which is used to build floating bridges. The utility model is composed of a pressure-bearable catamaran body (1), a connecting bridge (2), an overhang board (3) and a joint (4). The load-bearable catamaran with an overhang board is characterized in that a flexible rigid joint in the state of rigid when the floating bridge is floating and in the state of hinging when the beach fades is adopted. The catamaran can be made into two or four single boats with overhang boards which can be folded on the deck. A power plant can be installed on the catamaran body. The utility model can be used as a bridge approach for the constructions of harbors, ferries and bridge sluices, and for offshore beach oil drilling. Besides, the utility model has the advantages of easy installation and easy use. The utility model can also adapt to higher current velocity and pass through floaters, and the cost can be saved.

Description

Load-bearable catamaran with overhang boards

The utility model belongs to a kind of bearing load that lands, and is used to construct the binary boat (Fig. 1) of pontoon bridge.But it is made up of boat body (1), connecting bridge (2), the overhanging side of a ship (3), the joint (4) of pressure-bearing.

Till proposing the utility model, the equipment of generally constructing pontoon bridge is divided into four kinds.First kind, bank shoal pavement equipment.It is made up of inflatable air cushion road surface and densely covered steel semicircular cylinder road surface.This shoal, equipment opposite bank soil modulus of deformation has certain requirement, and is subjected to the restriction of the depth of water.Second kind is the pontoon bridge that is formed by bolted connection by boat body, bridge purlin, three main portions of decking.This pontoon bridge, complex structure is installed inconvenience, and labour intensity is big, and the operating personnel is many, and the pressure-bearing that can not land.The third is the belt pontoon bridge that is linked together by boat body and topside.It is easy for installation.But whole pontoon bridge does not have bridge opening, and boat takes the whole river width and the water surface, and water therefore can not adapt to high flow velocities, as it is more unfavorable to run into drift all from boat underflow mistake.The 4th kind is assembled by buoyancy tank, and it does not have bridge opening, can not adapt to high flow velocities, can not be used in the shoal pressure-bearing again.

The utility model in order to make a kind of pontoon bridge equipment, has multiple function exactly, but and has adopted the binary boat of the landed bearing load of being made up of boat body (1), connecting bridge (2), the overhanging side of a ship (3), the joint (4) of pressure-bearing.Its purpose mainly is to build for river, river, shoal, lake and seabeach, coastal waters, can adapt to float, Luo Tan, fall pontoon bridge under beach and the high flow velocities condition partly, and a kind of multiduty binary boat of being developed.

Characteristics of the present utility model: in the overhanging side of a ship end variable stiffness joint (Fig. 2) being installed, is rigidity when the pontoon bridge afloat, can be changed into hinged when falling the beach state; There are the connecting bridge and the overhanging side of a ship to form bridge opening between boat and the boat.To adapt to high flow velocities and to pass through drift.For convenience of terrestrial transportation, the binary boat can be cut at the connecting bridge middle part, manufacture two monomer boats (Fig. 3, Fig. 4) with the overhanging side of a ship, the overhanging side of a ship may be folded on the boat deck, also can cut at monomer boat middle part, manufacture four monomer boats with the overhanging side of a ship (Fig. 5, Fig. 6), the overhanging side of a ship may be folded on the boat deck; For convenience waterborne motor-driven, can on the boat body, engine installation be installed, become motor-driven binary boat; Also can be according to the requirement of different loads, the profile and the inner structure of boat body, connecting bridge, the overhanging side of a ship is designed to different size, joint also can be varying sized thereupon, and can adopt different materials.

The utility model compared with the prior art, be characterized in: can be in the river, river, shoal, lake construct the shoal pontoon bridge, make the oil drilling access bridge at the seabeach, coastal waters, can adapt to Luo Tan, Ban Luotan, showy various states, can on the river of big flow velocity, set up pontoon bridge; Can be used as pontoon bridge at the location of korneforos boat; Can construct ferry and port and pier; Can construct bridge, sluice construction suspension bridge; Can be used as the raft of pontoons crosses with dragging the traction of (pushing away) wheel to carry out groove; The binary boat is transformed a little, can be used as small-sized drilling vessel, small-sized crane ship, operation at sea platform etc.And simple in structure, connecting portion is few, has interchangeability, and is easy to install, be not subjected to the restriction of the depth of water, soil modulus of deformation, and can pass through drift.Overcome river, shoal, river and seabeach, coastal waters and adopt and fill out straw material soil with current, and jackstone fills out the method for leading the way and compare, save great amount of manpower and material resources, saving fund, remarkable in economical benefits.
