Abstract
The invention relates to an island constructing caisson structure for eliminating resistance to be fast towed. The structure comprises a caisson body, wherein the shape of one end of the head of the cross section of the caisson body is a pointed head. The shape of one end of the head of the cross section of the caisson body can be a triangular protrusion, a semi-oval protrusion, a semicircular protrusion, a triangle with the vertex angle being a chamfering angle. As an improvement, one end of the tail of the cross section of the box body is a sunken part corresponding to the one end of the head in shape. After the structure is adopted, due to the fact that one end of the head of the cross section of the caisson body is the pointed head, when the caisson is towed, resistance on the head of the caisson body of water flow is smaller than resistance on the head of a square caisson of the water flow, the caisson will not swing either, and the structure is safer in the transportation process. Due to the fact that the shape of the tail of the caisson body is arranged to the same as that of the head of the caisson body, the caisson structure can be installed more conveniently, the caisson body can be aligned more easily, and gap is not prone to generation.
Description
Technical field
The present invention relates to a kind of for building fast the caisset in cofferdam, island.
Background technology
Caisson is the indispensable important component part of waterborne building, marine vertical breakwater for example, port and pier, build fast cofferdam, island etc., when carrying out construction operation, all need to first place caisson at construction location, and then on caisson, carry out the construction of superstructure.The production of caisson is at present carried out conventionally on land, caisson is transported to marine job position after making again, and inevitably will carry out Caisson Transportation.Existing caisson mostly is square structure, and in when haul, current can produce larger resistance at the head of caisson, causes casing to wave being used as of fluid circulation is irregular, and the speed of a ship or plane is slower, wastes energy.In haul process, because casing is done irregular movement, can produce larger momentary action power to hawser, may there is the danger of hawser fracture.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can in haul process, reduce resistance to water-flow and easily abutting joint for building fast the caisson in cofferdam, island.
For solving the problems of the technologies described above, the resistance that disappears of the present invention is hauled and is built island caisset fast, comprises casing, and one end of described casing is tip.
The shape of described casing tip end can be the shapes such as triangle that triangular hill, half elliptic projection, semi-cylindrical hill, drift angle are rounding.
As a kind of improvement, the afterbody one end in casing cross section is the depression corresponding with head one end shape.
As a kind of improvement, the upper edge of casing one end is provided with nose girder, the upper edge of the other end be provided with described nose girder match guide groove.
Adopt after such structure, because one end of casing is tip, when haul, current can suppose that to the resistance of the tip of casing America caisson is little by 30%, and casing yet can not produce and wave, safer in transportation.And the shape with casing head that the shape of the afterbody of casing is arranged is the same, during installation, more easily front and back casing is alignd, and be not easy to produce gap.Because the upper edge at the two ends at casing is provided with nose girder and the guide groove matching, more easily alignment during installation.

The specific embodiment
Embodiment 1
As shown in Figure 1, the resistance that disappears of the present invention is hauled and is built island caisset fast, comprise casing, the shape of the head one end in described casing cross section is that drift angle is the projection of the shapes such as triangle of rounding, the depression of the shapes such as triangle that the afterbody one end in casing cross section is is rounding with head one end corresponding drift angle of shape.
Embodiment 2
As shown in Figure 2, of the present invention disappear resistance fast haul build island caisset, comprise casing, the head one end in described casing cross section be shaped as half elliptic projection, the afterbody one end in casing cross section be that semiellipse corresponding with head one end shape caves in.
Embodiment 3
As shown in Figure 3, of the present invention disappear resistance fast haul build island caisset, comprise casing, the head one end in described casing cross section be shaped as triangular hill, the afterbody one end in casing cross section is and the corresponding triangular shaped recess of head one end shape.
Embodiment 4
As shown in Figure 4, of the present invention disappear resistance fast haul build island caisset, comprise casing, the head one end in described casing cross section be shaped as semi-cylindrical hill, the afterbody one end in casing cross section is and the corresponding semi-cylindrical canyon of head one end shape.
The above, be only to preferred embodiment of the present invention, not the present invention done to other forms of restriction, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equal variation.Every the present invention program's content that do not depart from,, all drops in protection scope of the present invention any simple modification made for any of the above embodiments, equivalent variations and remodeling according to technical spirit of the present invention.
