Abstract
The invention discloses a combined type environment-friendly inflatable arch cofferdam capable of being flexibly combined, convenient to assemble and disassemble, environmentally friendly, economical and practical. Two rows of upright posts are connected through straight bars. Auxiliary bridge deck slabs are laid to build a temporary auxiliary bridge. An arc structure is formed by connecting arc bars on the upstream side of the upright posts to be subjected to stress. Installation holes are formed in the middles of the upright posts. Through grooves are formed in one side faces of the upright posts, and installation bars connected with a water blocking curtain can be inserted into the through grooves from top to bottom to install the water blocking curtain. The water blocking curtain is provided with post sleeves and bands. Inflatable cylinders are fixed in the water blocking curtain post sleeves. The inflatable cylinders are provided with wind pipes and bands, and the inflatable cylinders and the water blocking curtain form an elastic water blocking cofferdam body together to block water after the inflatable cylinders are inflated. Falling parts and digging ropes are installed on the other side of the water blocking curtain to make the other side of the water blocking curtain be tiled at the riverbed bottom to be resistant to seepage.
Description
Technical field
The present invention relates to a kind of temporary water retaining cofferdam in river course, water areas project construction, especially make the Assembled environmental inflation arch cofferdam of water-retaining cofferdam of post, bar combining structure and inflation waterproof composite fabric.
Background technology
At present, relating in river course, water areas project construction, temporary water retaining cofferdam generally adopts the traditional materials such as timber, mound, geotextiles to construct, cofferdam construction affects large, long in time limit by ambient conditions, after major project completion, often not in place to Temporary Cofferdam dismounting cleaning, discarded object affects river course, water environment.
Summary of the invention:
In order to overcome traditional timber, mound constructs temporary water retaining cofferdam to be affected greatly by extraneous execution conditions, long in time limit, Temporary Cofferdam is built, tear trouble open, cofferdam demolition cleaning is not in place, the discarded object left over affects the shortcoming of water environment, the invention provides a kind of Assembled environmental inflation arch cofferdam, this cofferdam installation and removal is convenient and swift, cofferdam can according to river course, status of the water area is by column, arch bar, straight-bar, dash curtain, inflatable columns body free splicing combines, affect little by execution conditions, duration is short, can be widely used in and need in the various Water-related Project constructions of Temporary Cofferdam dash, each parts of this Assembled environmental inflation arch cofferdam can independent assortment, reuse, discarded object is not produced after cofferdam demolition, very environmental protection and economical and practical.
The technical scheme that technical solution problem of the present invention adopts is: two row's column lower ends are squeezed in the soil in riverbed, column upstream face side connects to form arch structure by arch bar, two row's column straight-bar reinforcement by connection, above after bed board as make-shift bridge, on-the-spot needs can be met.Column and bar combination can repeat to extend, two ends, cofferdam and riverbank are fixed, dash curtain is fixed on column by mounting rod, inflatable columns body is arranged in the column sleeve of dash curtain, expands after inflation, and dash curtain form one can the elasticity water-retaining cofferdam body of stressed dash, inflatable columns body is delivered to arch bar water pressure together with dash curtain, arch bar is delivered to power on column, and column, arch bar, straight-bar composition overall structure, is delivered to water pressure the fixed end on riverbed and riverbank.In darker waters, column also can be socketed increases height, and pendant part guarantees that dash curtain is laid on riverbed part and can sinks to river bed, then by stay cord, dash curtain is laid on riverbed part and pulls open tiling antiseepage in river bed.
The invention has the beneficial effects as follows: adopt the Assembled environmental of arch structure inflation arch cofferdam force-bearing situation good; component is light; column, arch bar, straight-bar, inflatable columns body, dash curtain can be manufactured according to specification standardization; behind scene, combination meets construction requirement as required; cofferdam installation, dismounting, convenient transportation; can not produce discarded object, all components are reusable, very environmental protection and economical and practical.

Detailed description of the invention
In FIG, column (1), column (2), column (3), column (4) lower end is squeezed into riverbed and is fixed, straight-bar (6), straight-bar (7), straight-bar (8), straight-bar (9) respectively with column (1), column (2), column (3), column (4) connects, lay suspension bridge panel (20) above, arch bar (5) is arranged on column (1), column (3) outside, mounting rod (12), mounting rod (13) is first fixed with the bandage of the relevant position of dash curtain (10) respectively, then column (1) is inserted, fixing in installing hole in the middle of column (2), fix with bandage in the column sleeve that inflatable columns body (11) is arranged on dash curtain (10), pendant part (14), pendant part (15), pendant part (16) and stay cord (17), stay cord (18) stay cord (19) is contained in the outer side edges of dash curtain (10).
In fig. 2, column (1), column (2) are connected with straight-bar (6), suspension bridge panel (20) is laid on straight-bar (6), mounting rod (12) is inserted in column (1) installing hole, dash curtain (10) is fixed by bandage and mounting rod (12), inflatable columns body (11) is arranged in the column sleeve of dash curtain (10), and pendant part (14), stay cord (17) are connected with the outside at dash curtain (10).
When cofferdam is installed, first column (1), column (2), column (3), riverbed is squeezed in column (4) lower end, arch bar (5), straight-bar (6), straight-bar (7), straight-bar (8), straight-bar (9) is installed and is fixed to column (1), column (2), column (3), the correct position of column (4), is laid on straight-bar (6) suspension bridge panel (20), on straight-bar (9), dash curtain (10) respectively with mounting rod (12), mounting rod (13), pendant part (14), pendant part (15), pendant part (16), stay cord (17), stay cord (18) stay cord (19) connects, and the inflatable columns body (11) of unaerated is installed in the column sleeve of dash curtain (10), then mounting rod (12), mounting rod (13) inserts column (1), fixing in installing hole in the middle of column (2), by pendant part (14), pendant part (15), pendant part (16) and stay cord (17), stay cord (18), stay cord (19) paves antiseepage the outside of dash curtain (10) at the bottom of riverbed, finally gives inflatable columns body (11) inflation of inflation.During cofferdam demolition, first open inflatable columns body (11) tracheae sealing device air is progressively bled off, and reduce dash curtain (10) top, water is put into construction side gradually, when after the level of both sides, extract mounting rod (12), mounting rod (13), dash curtain (10) is taken out from water, finally remove arch bar (5), suspension bridge panel (20), straight-bar (6), straight-bar (7), straight-bar (8), straight-bar (9) also extracts column (1), column (2), column (3) column (4), after each parts split and arrange, next time reusable.
