The utility model discloses a protection subsea drainage riser's drum structure, its simple structure, easy dismounting can help the constructor quick, the safe construction operation of the protection drum of accomplishing subsea drainage riser.
Description
Technical Field
The utility model belongs to the technical field of the ocean engineering construction, concretely relates to protection seabed drainage riser's drum structure.
Background
At present, under the sea area condition, an offshore hoisting device is usually adopted to cooperate with a diver to operate, but because part of the marine engineering structure is designed into an integral structure, the diver needs to dive into the underwater structure to operate, when the construction operation of a protection cylinder of a seabed drainage stand pipe is carried out, because the traditional protection cylinder is of a conventional cylinder structure and adopts the integrated design of a cylinder body and a cylinder cover, constructors need to install and dismantle the protection cylinder at a position 20 meters underwater for a long time, and the protection cylinder is influenced by sea waves and hidden surges, so that a great safety risk exists.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a simple structure, easy dismounting, high protection seabed drainage riser's drum structure of security.
The technical scheme of the utility model is that: a cylinder structure for protecting a subsea drainage riser, comprising: apron, stack shell, lewis hole, rings, stopper, the apron is circular structure, the apron periphery is opened there are four notches, four rings have been arranged at the apron top, the stack shell is the hollow circular cylinder structure, open on stack shell upper portion has four outlets, and open the stack shell lower part has a plurality of lewis holes, four stoppers have been arranged at the stack shell top, stopper and notch block.
Further, a base is fixed at the bottom of the cylinder body and is of a circular ring structure formed by splicing two semicircular ring plates.
Furthermore, bolt holes are formed in the left end and the right end of the limiting block.
The utility model has the advantages that: the cylindrical structure for protecting the seabed drainage riser of the utility model separates the cylinder body and the cylinder cover of the cylindrical structure, and the cylinder body and the cylinder cover are respectively provided with the lifting hole and the lifting ring, so that the dismounting and mounting work of the cylindrical structure can be easily completed through the hoisting equipment on water, the construction efficiency is improved, the underwater construction time is shortened, and the safety risk of constructors is reduced; in addition, through the notch on the cover, stack shell top installation stopper to with notch and stopper block and fixed with the bolt, make cover and stack shell fixed firm, thereby strengthened the bulk strength and the stability of drum structure.
Drawings
In order to more clearly illustrate the embodiments or technical solutions in the prior art of the present invention, the drawings used in the description of the embodiments or prior art will be briefly described below, and it is obvious for those skilled in the art that other drawings can be obtained based on these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of a cylindrical structure for protecting a subsea drainage riser according to the present invention.
In the figure: 1-cover plate, 2-barrel body, 3-lifting hole, 4-lifting ring, 5-bolt hole, 6-limiting block, 7-notch, 8-water outlet, 9-base and 10-vertical water drainage pipe.
Detailed Description
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be mechanically coupled, may be directly coupled, or may be indirectly coupled through an intermediary. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, a cylinder structure for protecting a subsea drainage riser, comprises: apron 1, stack shell 2 (diameter 7.6m, height 7.4 m), lewis hole 3, rings 4, stopper 6, apron 1 is circular structure, 1 peripheral division of apron has four notches 7, four rings 4 have been arranged at 1 top of apron, stack shell 2 is the hollow circular cylinder structure, 2 upper portions of stack shell are opened there are four outlet 8, and 2 lower parts of stack shell are opened there are a plurality of lewis holes 3, four stopper 6 have been arranged at 2 tops of stack shell, stopper 6 and notch 7 block.
Preferably, a base 9 (diameter 11 m) is fixed at the bottom of the barrel body 2, and the base 9 is a circular ring structure formed by splicing two semicircular ring plates.
Preferably, the left end and the right end of the limiting block 6 are provided with bolt holes 5.
Before use, the cylinder structure is poured by a shaping steel die for three times, the outer die base 9 of the first bin is formed by sixteen templates, the maximum arc length of each template is 2.16m, the cylinder body 2 is formed by eight templates, and the maximum arc length of each template is 2.985m; when the internal mold is assembled, installing steel mold supporting chords and bracing for reinforcement; when the outer film is assembled, the outer film is reinforced by using split bolts and inclined struts; in addition, the barrel body 2 part of the first bin template is not disassembled firstly and is reserved as a reference support when the barrel body 2 template of the second bin is installed, the barrel body 2 template is installed after the barrel body 2 is bound with the steel bars, a protective layer cushion block is installed, and an inner mold is installed firstly and an outer mold is installed secondly; the construction method of the third bin is the same as that of the second bin.
When the marine drainage vertical pipe is used, the cylinder body 2 and the cylinder cover 1 are sequentially lifted to the upper part of the seabed drainage vertical pipe 10 by using marine hoisting equipment to be installed, so that the drainage vertical pipe 10 is positioned in the cylinder body 2; then, the two semicircular plates are lifted to the specified positions to form a base 9 which is fixedly and stably fixed with the cylinder body 2; when in disassembly, the base 9, the barrel body 2 and the barrel cover 1 are disassembled in sequence; it should be noted that, when the locking groove 7 on the cylinder cover 1 is locked with the limiting block 6 on the cylinder body 2, a bolt can be inserted into the bolt hole 5 on the limiting block 6 to fix the cylinder body 2 and the cylinder cover 1 more stably.
The embodiments of the present invention have been described with reference to the drawings, but the invention is not limited thereto. It should be understood by those skilled in the art that various non-inventive changes and substitutions may be made without departing from the scope of the invention as defined by the appended claims.
