Abstract

The utility model relates to a mud mat type underwater foundation which is provided with a mud mat. A plurality of skirtboards are installed below the mud mat, and a plurality of reinforcing flitches are installed on the side face of each skirtboard. The mud mat is symmetrically provided with a plurality of suspension points. A plurality of underwater robot handles are symmetrically installed on the side faces of the mud mat. A plurality of anodes are distributed on both sides of the mud mat, and prefabricated anode baffles are distributed inside the anodes. The foundation provided by the utility model not only can provide support to the upper structure, so that underwater structures can freely slide on the mud mat, but also the subsea pipeline expansion is enabled to be adequately released. Meanwhile, the foundation further prevents a seabed from being damaged by the mud mat when mud is attached to the mud mat, so that the bearing capacity and the anti-skidding stability of the mud mat are improved.

Description

Anti-settling board-like underwater foundation
Technical field
The utility model relates to the underwater foundation of underwater production facility, relates in particular to a kind of anti-settling board-like underwater foundation that stable support is provided for underwater production facility.Belong to the Offshore Engineering field.
Background technique
Underwater production facility is because the impact that is subjected to the depth of water and maritime environment is less, is specially adapted to the exploitation in the deep water hydrocarbon field under complicated weather conditions.And underwater production facility needs a stable basis could the long-time running reliably in the seabed.
At present, underwater production facility base form commonly used mainly contains: basic three kinds of pile foundation, suction pile basis and mud mat.Wherein, the characteristics such as the mud mat basis is simple with its structural type, build process is ripe and installation method is convenient become the base form of underwater production facility first-selection gradually.
Usually, when production facility was connected with the sea pipe under water, the medium of High Temperature High Pressure made the sea pipe produce axial thermal expansion by extra large Guan Shihui, if thermal expansion can not be absorbed or discharges, easily causes the damage of flexing or the structure of extra large pipe.In order to solve the axial thermal expansion problem of extra large pipe, usually, adopt the mode that connects expansion bends to absorb the thermal expansion of extra large pipe.But because expansion bends need to be after pipe laying be completed, then is connected with the sea pipe by connecting facility, therefore, construction and mounting cost are higher, even because the depth of water can not be implemented too deeply.In order to address the above problem, adopt to discharge the method that the sea pipe axially expands, to discharge the expansion of extra large pipe.The method is: on mud mat, coastal tube swelling direction arranges slide rail, and when extra large tube swelling, underwater production facility can slide along slide rail, thereby discharges the expansion of extra large pipe.But this scheme mechanism more complicated is built difficulty, and exists and block risk, therefore, needs a kind of simple and reliable scheme that can absorb extra large tube swelling.
The model utility content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of anti-settling board-like underwater foundation, it not only can be free to slide underwater structure for superstructure provides support on mud mat, and extra large tube swelling is measured with abundant release; Simultaneously, can also prevent from when mud mat from mud, sea bed being produced and destroy, improve bearing capacity and the stability against sliding of mud mat.
The purpose of this utility model is realized by following technological scheme:
A kind of anti-settling board-like underwater foundation is provided with mud mat, and it is characterized in that: the below of mud mat is equipped with several skirtboards, and the skirtboard side surface all is equipped with several and strengthens pasting board.
Described mud mat is made by steel plate, has been arranged symmetrically with several suspension centres on mud mat; The mud mat side is symmetrically installed with several underwater robot handles; The both sides of mud mat are furnished with several anodes, and anode inner side is furnished with prefabricated anode baffle.
Described skirtboard is rectangular configuration.
Described reinforcement pasting board is triangle or trapezium structure.
The beneficial effects of the utility model:
1. it not only can be free to slide underwater structure for superstructure provides support on mud mat, and extra large tube swelling is measured with abundant release.
2. prevent from when mud mat from mud, sea bed being produced and destroy, improved bearing capacity and the stability against sliding of mud mat.
Simple, install convenient, to take sailing date shorter.
4. reduce cost of production, improved economic benefit.

Fig. 1 is perspective view of the present utility model.
Fig. 2 is that the utility model vertically lifts schematic diagram.
Fig. 3 is the utility model level lifting schematic diagram.
Major label description in figure:
Mud mat, 2. weep hole, 3. skirtboard, 4. strengthen pasting board, 5. suspension centre, 6. handle, 7. anode, 8. anode baffle.
Embodiment
As shown in Figure 1, the utility model is divided into two-part take the mud face as the boundary: the above structure of mud face and the following structure of mud face, and wherein, the above structure of mud face is: the mud mat 1 that an area is larger, this mud mat 1 is made by steel plate, and its effect is to provide support for superstructure.Mud mat 1 is provided with several weep holes 2, and the pitch-row of several weep holes 2 is 250mm, and diameter is 50mm, so that draining alleviates the added mass of entrained water when installing.The following structure of mud face is: several skirtboards 3, and this skirtboard 3 is rectangular configuration, and adopts welding or bolt connecting mode to be arranged on the below of mud mat 1, the effect of skirtboard 3 is for the bearing capacity that improves mud mat and stability against sliding.In order to keep the structural strength of several skirtboards 3, adopt welding manner to be equipped with between several skirtboards 3 and strengthen pasting board 4, strengthening pasting board 4 is triangle or trapezium structure.
During use, the setting type of skirtboard 3 and stiffening plate 4 and quantity are determined by the soil values of superstructure position, weight and present position.In addition, also have some accessory structures, for example: suspension centre, underwater robot (ROV) handle 6 and anode 7.Because sliding, top equipment needs, so, can only bury tubular suspension centre 5 underground on mud mat 1.Mud mat 1 after crossing splash zone, changes level lifting (as shown in Figure 3) by adopting the lifting mode lifting entry (as shown in Figure 2) of vertical lifting before splash zone into, therefore, determine that the suspension centre number is 8, and be the symmetric type layout.6 four or six of underwater robot handles are symmetrically welded at the side of mud mat 1.Anode 7 needs is avoided the both sides that top equipment glide direction is arranged in mud mat 1.For preventing equipment collision anode 7, it is inboard that prefabricated anode baffle 8 is arranged in anode 7 positions.
The above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
