Detailed Description
In order to solve the problems that the box body is difficult to sink when the box body is pressed by a box sealing method, soil around the box body needs to be emptied firstly when a bottom joist is installed, the construction amount is large and the like, an arc beam non-contact integral salvaging device is developed, only a locating and fixing framework such as a top beam and an end plate is needed to be positioned and installed, and the arc beam at the bottom is installed after the locating and fixing framework is sunk, so that an object to be salvaged is integrally sealed and then fished out.
The following describes the sectional top beam structure for fishing of the arc beam non-contact integral fishing device with the specific embodiment and the attached drawings.
Referring to fig. 1 and 2, a sectional top beam structure for salvaging an arc beam non-contact integral salvaging device comprises two top beam groups which are vertically and detachably connected between two end plates and respectively detachably connected with two ends of a plurality of arc beams in series, wherein each top beam group comprises two top beams 1 which are arranged side by side, a gap 2 for inserting the ends of the arc beams is reserved between the two top beams 1, the top beams 1 are sectional structures, and each top beam 1 is formed by splicing two fixed sections 11 positioned at the two ends and at least one standard section 12 positioned between the two fixed sections 11.
Specifically, the two top beam groups are connected to two opposite sides of the two end plates, the top surfaces of the two top beam groups are flush with the top surfaces of the two end plates, the two top beam groups and the two end plates together form a positioning fixing frame capable of surrounding an object to be salvaged, the positioning fixing frame only needs to be sunk when salvaged, after sinking in place, the semi-circular arc beams are transmitted one by utilizing the transmitting frame, so that a plurality of arc beams are used as bottom joists of the object to be salvaged to be laid side by side and blocked at the bottom of the positioning fixing frame, and a container structure covering the object to be salvaged is formed. The top beam group is arranged at intervals by double top beams, and an insertion gap 2 is reserved at two ends of the arc-shaped beam. The top beam structure of the invention is fully matched with the rear mounting form of the arc beam, meets the design purpose of the salvaging device, and solves the problems that the box body is easy to sink and the soil body around the box body needs to be emptied firstly when the bottom joist is mounted, the construction amount is large and the like when the box body is pressed down by a box sealing method. In addition, the sectional top beam structure is adopted, so that the length can be flexibly adjusted, the fishing device is suitable for fishing devices with different length requirements, and the transportation and the structure disassembly and assembly are convenient.
