Description
Technical Field
The invention relates to the technical field of building construction, in particular to a self-floating template applied to deep ocean and a method for constructing and launching a concrete floating island.
Background
Most of the traditional ocean platforms are made of steel, and steel is extremely easy to corrode in the salt-rich environment of the ocean, so that the steel ocean platforms are maintained frequently. Steel ocean platforms are generally required to be hauled from ocean to dock near continents for maintenance, the hauling cost is extremely high, and the process risk is very high; and the steel platform is relatively light in weight, so that the stability on the sea is relatively poor. Therefore, the assumption that the deep ocean platform is built by using concrete is proposed, and the limitation above the steel platform can be broken through.
However, since concrete construction generally requires dry ground, it is generally necessary to cofferdam a construction area before a concrete structure in water is constructed, drain the water in the construction area to form dry ground, construct the concrete structure, and remove the cofferdam after the construction is completed to restore the original water area state. However, the construction method of the cofferdam cannot be adopted in deep ocean.
If the concrete material is used for constructing the deep sea ocean floating island, the traditional large offshore concrete structure can be only used for modular design and construction, and the construction mode is divided into three steps: firstly, prefabricating a floating island module on land; secondly, launching the floating island and conveying the floating island module to a designated sea area; and thirdly, carrying out installation on site.
The floating island module has huge mass and size, and a prefabricated site is often fixed in an offshore area in order to reduce land transportation distance; to transport large offshore heavy structures, modules are often transported from land to the working sea using offshore towing and the like.
The offshore transportation of the floating island module means that the floating island module prefabricated on land is firstly subjected to self-floating launching by adopting a water-pouring method (see the self-floating launching process of the immersed tube tunnel of the bridge in majonaugh harbor, pearl and Australia), and then is towed to an offshore installation site by adopting a barge or utilizing a self buoyancy device through a tugboat. The key of marine towing is the selection of towing vessels and the exploration towing route. The tug has enough power, can correctly control the stability of the towed structure under the set marine environment condition, and keeps a certain navigational speed; the towing route should avoid sea areas where sea damage accidents may occur and where the sea areas are affected by bad weather.
The integral floating installation method on the sea comprises a floating installation method and a jacking installation method. Need the anchoring location during the installation of floating support, alignment floating island module and pile foundation's mounted position guarantees that the floating island module does not collide with the instant of stake butt joint, consequently installs the floating island module through the floating support mounting method at present and must accomplish under the fine condition of weather condition, receives the climate constraint great. When jacking and installing, the floating island module is towed to the position near the pile foundation by one barge, then the floating island module is lifted from two sides by two barges with high-power windlasses and lifting rigid arms and slowly moved forwards to the upper part of the pile foundation, and the butt joint of the floating island module and the pile foundation is completed through the lifting rigid arms. When the jacking installation method is used for offshore operation, all loads act on the two floating barges, and the operation is very difficult to control, so that the offshore construction difficulty is high, the safety is difficult to grasp, and the installation weight and the application range are limited.
At present, the transportation cost of the floating island construction method for hauling the land precast concrete floating island to the site is extremely high, the precast site is limited, the assembly and manufacture concealment is poor, the influence of the fluctuation of the offshore environment is great during installation, and the construction speed of the floating island and the volume of the floating island are extremely limited.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
In view of the high transportation cost, the environmental influence, the poor construction efficiency and the poor construction safety in the prior art, the embodiment of the invention provides the self-floating template applied to the deep ocean and the method for constructing and launching the concrete floating island, so as to reduce the transportation cost and the environmental influence and improve the construction efficiency and the construction safety of the concrete floating island. The present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of the self-floating template assembly applied to deep ocean in an embodiment of the present invention. As shown in fig. 1, the self-floating template includes:
a template sinking and floating control device 1 and a template surface 6.
The template floating and sinking control device 1 is arranged on the template surface 6 and is used for controlling the template surface 6 to float, sink or hover in liquid (such as water). In specific implementation, the template surface 6 is used for supporting the hardening and forming of fresh concrete and is a reference surface for hardening and changing the cementing material from a slurry state into a stone body and cementing other materials. The template sinking and floating control device 1 can change the sinking and floating of the template and the accessory components thereof by changing the resultant force direction of the template surface and the accessory components thereof in the vertical direction.
In one embodiment, the template sinking and floating control device 1 consists of a water pump and a cavity; the water pump is communicated with the cavity and liquid outside the template surface 6 and is used for adjusting the liquid in the cavity to control the template surface 6 to float, sink or hover in the liquid.
Alternatively, the stencil floating and sinking control means 1 may be a power means for generating vertical power to control the stencil surface 6 to float, sink or hover in the liquid. When the template sinking and floating control device 1 generates an upward force, the template surface 6 floats upwards; when the formwork sinking and floating control device 1 generates a downward force, the formwork surface 6 sinks.
In one embodiment, the self-floating template further comprises: the propeller is arranged on the template surface 6 and used for pushing the template surface 6 to move in the horizontal direction.
In one embodiment, the self-floating template further comprises: a connecting member; the connectors are used to connect at least one template face 6 to form a self-floating template assembly 2.
In specific implementation, the connecting piece is connected with the template to form the self-floating template assembly 2, and the template comprises at least one template surface 6. As shown in fig. 1, the formworks may include a bottom plate formwork 4 and a circumferential formwork 5, and one bottom plate formwork 4 and four circumferential formworks 5 form a self-floating formwork assembly 2. The bottom plate template 4 and the circumference template 5 in fig. 1 are both template surfaces 6 provided with the template sinking and floating control device 1. The template can also adopt a common template without the template sinking and floating control device 1, as long as one of the templates is the template surface 6 with the template sinking and floating control device 1.
In one embodiment, the self-floating template further comprises: a drainage space 3 enclosed by at least one formwork surface 6.
In particular, the drainage space 3 is defined by formworks (e.g., the formworks may include a bottom formwork 4 and four perimeter formworks 5 as shown in fig. 1). Since concrete is required to be constructed on dry ground, a space free from water is required to be obtained from the drainage space of the floating form to achieve the condition of dry ground construction. As shown in fig. 1, the drainage space 3 is used to obtain a drainage amount (e.g., a drainage amount) that offsets the weight of the concrete floating island to be constructed so that the concrete floating island to be constructed does not sink, while forming dry ground to satisfy the dry ground construction conditions (cement dry ground construction conditions) of the concrete floating island. The concrete floating island to be built comprises a concrete floating island body, mechanical equipment attached to the concrete floating island body, mechanical equipment used for building the concrete floating island, constructors and construction materials, and the total water discharge of the drainage space 3 and the self-floating template combination is larger than the sum of the respective water discharge of the templates. For example, taking fig. 1 as an example, the displacement of the drainage space 3 is a, the displacement of the self-floating formwork assembly is B, and the displacement of the five formworks (including one floor formwork 4 and four perimeter formworks 5) in fig. 1 is C1, C2, C3, C4 and C5, respectively. Then A + B > C1+ C2+ C3+ C4+ C5.
The inner wall of the drainage space 3 can also be used as a formwork surface. During specific implementation, a dry land environment can be obtained by discharging water in the drainage space 3 so as to be beneficial to concrete dry land construction, and the draft of the self-floating template assembly 2 can be adjusted by changing the water amount in the drainage space 3 and jointly controlling the template sinking and floating control device 1.
In one embodiment, the self-floating template may further comprise a water valve (not shown in fig. 1). The water valve is arranged on the template of the self-floating template assembly 2 and is used for communicating or cutting off the drainage space 3 and the liquid outside the self-floating template assembly 2. Opening the water valve can connect the drainage space 3 with the water outside the self-floating template assembly 2; closing the water valve prevents the drainage space 3 from communicating with water from outside the floating template assembly 2.
In one embodiment, the self-floating template further comprises: the drain pump for draining the liquid in the drain space is provided on the template of the self-floating template assembly 2, and can drain the liquid in the drain space 3 to the outside of the drain space 3.
Based on the same inventive concept, the embodiment of the invention also provides a method for constructing the launching by the concrete floating island of the self-floating template applied to the deep ocean, and as the principle for solving the problems of the method is similar to that of the self-floating template, the implementation of the method can be referred to that of the self-floating template, and repeated parts are not repeated.

In one embodiment, S101 includes: the template sinking and floating control device 1 is fixed on the template surface 6 and is connected with at least one template surface through a connecting piece to form a self-floating template assembly to form a drainage space 3. When the self-floating template assembly is implemented, the self-floating template assembly is formed by connecting a plurality of templates through connecting pieces, and each template comprises at least one template surface.
In one embodiment, the forming of the drainage space 3 further comprises: the water in the drain space 3 is drained by controlling a drain pump provided on the template of the self-floating template assembly. Fig. 3 is a schematic diagram of a position change of a self-floating template assembly. As shown in fig. 3, a in fig. 3 is a self-floating formwork assembly after water is supplied, and when water is supplied from the self-floating formwork assembly, a drainage pump needs to be controlled to drain water in the drainage space 3 to change the original drainage space to a dry ground, so as to facilitate the construction of a concrete dry ground. Meanwhile, the template sinking and floating control device 1 can be started according to the depth position of the self-floating template assembly to enable the self-floating template assembly to float upwards. As shown in fig. 3 b and c, the water in the floating template assembly is completely discharged after the drainage pump is started, floats up from the floating template assembly and the original drainage space becomes dry, and preparation is made for building the concrete floating island.

FIG. 5 is a schematic illustration of a separation template in an embodiment of the present invention. As shown in a diagram in fig. 5, when the concrete floating island is built to have a self-floating condition (the concrete is hardened to a certain threshold value or the water displacement of the self-floating template and the concrete floating island is a preset multiple of the self-weight), a water valve or a control connecting piece is opened to form a template gap, and the drainage space 3 is communicated with the sea, so that the self-floating of the concrete floating island is realized.
S103: separating the individual templates that make up the self-floating template assembly.
In particular, as shown in b of fig. 5, the connectors may be controlled to separate the individual forms (including the floor form and the perimeter form) that make up the self-floating form assembly and to pull the perimeter form away from the current concrete floating island.
S104: and sinking the template surface to a preset safe depth by controlling the template sinking and floating control device.
Wherein, the safe depth is apart from the concrete floating island by preset vertical safe distance.
As shown in fig. 5 c, the formwork sinking and floating control device 1 on the bottom formwork 4 (formwork surface 6) can be controlled to make the bottom formwork 4 continuously separate from the bottom of the concrete floating island and continuously sink until the bottom formwork 4 and the concrete floating island have a sufficient safety distance in the vertical direction.
As can be seen from the process shown in fig. 2, in the method for constructing a concrete floating island for a self-floating template in deep ocean according to the embodiment of the present invention, at least one template surface is assembled into a self-floating template assembly, then the concrete floating island is constructed on the template, then the templates are separated, and finally the template surface is sunk to a preset safe depth by controlling the template sinking and floating control device, so that the concrete floating island can be constructed on water to reduce transportation cost and improve the construction efficiency of the concrete floating island, and the draught depth of the self-floating template can be changed to reduce environmental impact, thereby further improving construction safety.
In one embodiment, after executing S104, the method further includes: moving the template surface 6 to a preset safety position by controlling a propeller arranged on the template surface 6; the template surface 6 is floated to the target depth by controlling the template floating control device 1. Wherein, the safe position is apart from the concrete floating island by a preset horizontal safe distance.
FIG. 6 is a schematic illustration of the floating of the template surface in an embodiment of the present invention. As shown in fig. 6, the propeller is controlled to push the bottom plate formwork 4 (formwork surface 6) to move, so that the bottom plate formwork 4 and the concrete floating island are staggered from each other in the horizontal direction by a sufficient safety distance, and then the formwork sinking and floating control device 1 is controlled to float the bottom plate formwork 4 to a target depth, so that the bottom plate formwork 4 can be dragged out for reuse at a later stage.
