Description
Technical field
The present invention relates to one and close on combined emergency flood-control wall between deep big sub-depressed place.
Background technology
At present, in immersed tube prefabrication of tube section is constructed, main is prefabricated place with dry-docking, dry-docking need to experience excavation, prefabricated, pour water, the complex working condition such as fitting-out, dock entrance are abolished, recover, backfill, owing to taking up an area, scale is big, engineering cost is high, seepage prevention system requires tight, big on duration impact, and dry-docking scale is still based on small-sized, medium-sized, and it is longer to cross river/river/seabed immersed tube tunnel, pipeline section quantity is many, needs the most prefabricated, transportation by driving, sinking, docking.
But, section floating, sinking are all selected flood season, Nanchang district persistently nearly half a year in flood season, and sequence of construction mostly is prefabricated limit, limit transportation by driving, so that, closing on sub-depressed place still in prefabrication phase flood season temporarily.Using long tube back-up sand or earth dam flood-control wall traditionally, long construction period, recovery utilization rate are low, civilized construction is poor.
Summary of the invention
The problem that it is an object of the invention to exist for existing flood-control wall, one is provided to be used for closing on combined emergency flood-control wall between deep big sub-depressed place, between two sub-depressed places, prefabrication of tube section, transportation by driving form line production, it does not interfere with each other, being effectively reduced the potential safety hazard that antithetical phrase in flood season depressed place is brought, Steel Structure Installation progress is fast, and steel recovery utilization rate is higher, remarkable in economical benefits, civilized construction is guaranteed.
Of the present invention close on combined emergency flood-control wall structure between deep big sub-depressed place and include: bottom gravity type plain concrete wall, plain concrete, top built-in connection, embedded board, bolt, steel construction flood-control wall, bottom grade beam, shaped steel diagonal brace at dowel, steel superstructure flood-control wall, shaped steel column, angle steel skeleton, steel facing, lower anchor slab, stiffener, connecting bolt, passage;
Described bottom gravity type plain concrete wall includes plain concrete, top built-in connection, and top built-in connection includes embedded board, bolt, dowel;Dowel and embedded board two-sided welding;
Described bottom gravity type plain concrete wall steel superstructure installed above flood-control wall;Its structure includes shaped steel column, horizontal corner steel skeleton, steel facing, lower anchor slab, stiffener, bolt, shaped steel column is connected by groove welding with lower anchor slab, stiffener, lower anchor slab is bolted with embedded board, and steel superstructure flood-control wall and bottom gravity type plain concrete wall are formed by bolt and be effectively connected.
Longitudinally disposed 2 road angle steel skeletons, angle steel skeleton is connected with Type of Welding with shaped steel column connecting portion, the every 5 butt head two root type steel column wing plate borings of shaped steel column, hole dimension is consistent with termination, steel facing both sides bore size, shaped steel column is bolted with steel facing, and steel facing and angle steel skeleton are by being welded to connect;
At described passage, steel construction flood-control wall is arranged at the roof panel docking sidewalk mouth of depressed place;
Outside at described passage, the structure of steel construction flood-control wall is identical with steel superstructure flood-control wall, also at passage, steel construction flood-control wall shaped steel column both sides increase by four root type steel diagonal braces, and shaped steel diagonal brace is welded to connect with shaped steel column, steel facing.
The invention has the beneficial effects as follows: use a kind of relatively simple combined emergency flood-control wall, it is achieved that in flood season, prefabrication of tube section, transportation by driving do not interfere with each other, safety is guaranteed, eliminates flood season to section floating, the prefabricated potential safety hazard brought.
