New description: [New technical field] The case is related to the structure of a workbench, especially a workbench that can float on water or under water. The so-called workbench is mainly used for the production of caisson. [Prior Art] The caissons are commonly used in the construction of waters. Most of them are first. • Make a box of reinforced concrete in a suitable place. If it is not ready for floating, if it is not yet scheduled. Height, can be towed to safety = domain to continue construction, if the predetermined height has been completed, then tow to the intended construction position, so that the caisson sinks into the water, and fills the inside with sand and other objects, as a fixture . There are at least two ways to make a caisson. One is on the floating platform, the target is L. The second is on the land or on the beach. The construction on the floating platform is easier to control the weather, currents and construction sites, but the cost is high and the number of simultaneous applications is limited. The construction method on the land or on the beach is often carried out when the caisson is applied to a certain height (with some buoyancy), and it is towed to the predetermined water area (sea, river or lake, etc.) and then continued to be moved. Difficulties often arise in the process. For example, when the operation of the caisson is removed and the operation of the channel is cleaned, the unevenness of the bottom of the caisson is often caused to cause rupture, which causes the caisson to sink and cause losses. Therefore, 'to achieve (1). Work platform with excellent working environment, (2) · Multiple caisson can be made at the same time, (3). Easy to make the caisson to float on the water, (4) _ easy to drag the caisson The production location is reworked or deposited for the M351233 industry, and (5). The work site can be reused many times, which is an important consideration. In addition, how to keep it in the undulating water surface such as tidal range and the smooth separation of the caisson from the construction platform during the application of the caisson are also important factors that must be considered. [New content] ' The main purpose of this case is to provide a work φ table for making caisson, which provides a floating structure in a circle of water, which can float when buoyancy is injected into the air. When it releases air, it will sink; this way, it can provide a floating table when making the caisson. When the caisson is made to a predetermined state (such as when the caisson can float), it can be made according to requirements. The workbench sinks and separates from the sink. The second objective of the present invention is to provide a workbench which is composed of a base and an air container, which can be used for caisson or other purposes on the base, and the air container can be injected or released. Air to provide the buoyancy required for the base and its φ load. The air container of the present case may be an air bag or a fixed-shaped container. [Embodiment] As shown in the first and second figures, a water zone 10 having a predetermined water depth is disposed in the cofferdam, the so-called cofferdam including at least one stable bank 21, and side banks 22, 23 and at least A detachable or movable gate area 24; the workbench 30 of the present case is disposed in a water zone 10 M351233 surrounded by the so-called bank 21, side banks 22, 23 and the gate area 24. The water area around this circle is 1 〇, which can reduce the fluctuation of the water level. The shape of the water zone 10' referred to above by the weir is not limited to a rectangle. The workbench 30 is composed of at least a base 31 and an air receiver 32 disposed under the base 31; it is characterized in that the air is contained so that the air can be filled or released when an appropriate amount of air is injected. After that, the whole work can float on the water; when the construction on the base 31 of the worktable 30 is increased, the weight can be increased at any time (for example, the application of silk 40). Appropriate amount of air in the so-called air container 32, can maintain the workbench 3 floating on the water; until the caisson 40 and so on to the predetermined shape (for example, sinking on -b When the mouth is from the ocean or the work, etc.), the I! Π in the air receiver 32 is discharged, and the workbench 30 and the gradual sinking (as in the third figure, the seat 31 and the Ϊ 4 〇 can be self-occupied, the caisson After the bottom of the 4th and the workbench 30 are separated from each other, the workbench 3〇 can be submerged in the water, the phase 40 is removed from the water zone 1{), and the air container 32 is gradually injected. The 3G can be floated again.杈31 household Γ冉31 'In order to make it more stable, several branches can be set on it, and the u' pillar 311 can be nailed into a stable position (such as underwater land), and the inspection 311 can be placed on the pedestal. 31 in the object, so that the work m ^ circle and other cheeks 4 mouth 30 due to the water level can be longitudinal movement with the pillar 311, reducing lateral displacement or shaking. The continuous salary is called the air container 32, which can be an air-filled object, which can be placed under the base 31 in a manner such as 9, I, etc., M351233, the so-called airbag can be injected with air. The shape is also expanded due to the need (the shape is not limited). The balance and stability of the susceptor 31 can be controlled by forming a long strip shape and arranging a plurality of them under the susceptor 31, and by injecting or releasing air to the airbag in synchronization, alone, or the like. The air container 32 as described above may also be in the form of a fixed outer casing, and a hole is provided below the hole. When the inside of the air is filled with air, the water inside the liquid can be discharged, and when the air is released, the water and the liquid are Can be filled in naturally. The base 30 and the air container 32 can be flexibly used. For example, the base 31 can be provided with various working fasteners, etc., or can be applied to a plurality of openable areas to enable the object to be The base 31 faces the air receiver 32 or underwater; or the so-called air container 32, which can be elastically arranged (the positions are not arranged), or overlapped, etc., to enhance the functionality or work together. Demand. The disclosure of the present invention is a preferred embodiment. Any part of the change or modification of the present invention originating from the technical idea of the present invention is easy for a person familiar with the skill to infer, and does not deviate from the patent right of the case.
