Description
Technical field
The present invention relates to a kind of construction method of concreting, especially a kind of concreting at greater coasting area sea
Construction method.
Background technique
The effect of anti-collision alarm pier is warning shippping traffic, guarantees the structures safety within the scope of caution mound；Project is located at sea
In domain, there is a certain distance apart from land-based area, general offshore concrete is poured using mixer ship or marine plate oceangoing ship ship voluntarily stirs
And pour two ways；But since caution mound amount of concrete is typically small, and placement layer by layer is needed, poured often；Using stirring
Ship, which pours, or plate oceangoing ship ship is voluntarily stirred and poured causes construction cost high, and construction period due to concreting often,
It is not continuous placing, mixer ship or plate oceangoing ship ship work holdup phenomenon are serious, and ship machinery utilization rate is low.Therefore feed bin+cargo ship+
Crane ship sea concrete construction method can under the premise of guaranteeing concrete pouring quality and controllable construction safety risk
Construction cost is substantially reduced, and avoids ship machinery work holdup phenomenon.
Summary of the invention
The present invention is to provide for a kind of construction method that greater coasting area offshore concrete pours, and this method can solve neritic zone
Domain sea pours that a small amount of concrete construction is at high cost, the problem of ship machinery utilization rate low efficiency.
To solve the above problems, the technical scheme is that a kind of construction party that greater coasting area offshore concrete pours
Method, construction site configure two ships, and one is crane ship, and another is cargo ship；Setting feed bin is transported on the transport deck of boat
Defeated concrete, the steps include:
1) concrete mix slump-loss and setting time test data sheet and single cargo ship transport concrete are combined
The time that need to be consumed with crane ship casting concrete determines the amount of single cargo ship transport concrete；
2) concrete is transported to harbour and is delivered in feed bin by concrete placement vehicle；Feed bin is filled to fortune from wharf crane by truck crane
On defeated ship；
3) cargo ship is by feed bin inner concrete to construction area, and ship is rested in crane ship side, crane ship by feed bin by
Cargo ship is lifted to template, after feed bin is stablized, is opened feed bin valve, is leaned on concrete gravity, concrete is fallen in template；
4) cargo ship band sky feed bin is rapidly returned to harbour, and feed bin is hung to harbour by truck crane, repeats above step construction.
Further, the slump test data provided according to laboratory consider the selection of time transport of single fortune concrete
Feed bin volume on the deck of boat.
Further, the amount of the determining single cargo ship transport concrete is 7m3。
Further, the construction method that the greater coasting area offshore concrete pours is suitable for greater coasting area anti-collision alarm pier class
Like engineering, single casting concrete amount is few, pours operating condition often.
The beneficial effects of the present invention are:
The more conventional offshore concrete of construction method of the invention is poured using mixer ship or plate oceangoing ship ship is voluntarily stirred and poured
The construction method built:
1) guarantee that construction cost can be substantially reduced under the premise of concrete pouring quality and construction safety risk are controllable；
2) ship machinery work holdup phenomenon is avoided.
The present invention can solve the similar items offshore concretes such as greater coasting area anti-collision alarm pier (single casting concrete amount
It is few, and pour often) the problem of pouring；This construction method is guaranteeing that concrete pouring quality and construction safety risk are controllable
Under the premise of, generally use that mixer ship pours or marine plate oceangoing ship ship voluntarily stirs and pours two ways and drops significantly compared to marine concrete
Low construction cost, and avoid ship machinery work holdup phenomenon；It can be applied in the similar engineerings such as anti-collision alarm pier.
Detailed description of the invention
Fig. 1 is the construction method construction process figure of greater coasting area concreting of the invention.
Specific embodiment
The present invention is further illustrated with embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of construction method of greater coasting area concreting, is suitable for greater coasting area anti-collision alarm pier class
Like engineering, single casting concrete amount is few, but pours operating condition often；Construction site configures two ships, and one is lifting
Ship, another is cargo ship；It transports setting feed bin on the deck of boat and carries out transport concrete, and tried according to the slump that laboratory provides
Data are tested, the feed bin volume on the selection of time transport deck of boat of single fortune concrete is considered, the steps include:
1) concrete mix slump-loss and setting time test data sheet and single cargo ship transport concrete are combined
The time that need to be consumed with crane ship casting concrete determines the amount 7m of single cargo ship transport concrete3(two 3.5m3Feed bin)；
2) concrete is transported to harbour and is delivered in feed bin by concrete placement vehicle；Feed bin is hung on cargo ship by truck crane；
3) cargo ship is by feed bin inner concrete to construction area, and ship is rested in crane ship side, crane ship by feed bin by
Cargo ship is lifted to template, after feed bin is stablized, is opened feed bin valve, is leaned on concrete gravity, concrete is fallen in template；
4) cargo ship band sky feed bin is rapidly returned to harbour, and feed bin is hung to harbour by truck crane, repeats above step construction.
Application implementation example of the present invention
Engineering is nuclear power projects intake region anti-collision alarm pier, this engineering is on the outside of one phase of recirculated water~tri- phase intakes
Region creates 6 anti-collision alarm piers, and pier body divides two layers, upper layer pier body diameter 2m, high 3m, the high 8m of top mark, lower layer pier body diameter 7m,
High 2.5m, the high 5m of top mark, lower layer's pier body, which divides two layers, to be poured.Consider that stake top fills out core, this project cubic amount of concrete waterborne is a total of about
680m3, nearly 700m3.By using the present invention, this engineering adds up casting concrete 21 times, and during which safe condition is controllable, concrete
Pouring quality meets specification, design requirement；Calculated by project cost, using the present invention, is applied compared to mixer ship casting concrete
Work method reduces construction cost about 1,700,000；Compared to the construction method that plate oceangoing ship ship is voluntarily stirred and poured, construction cost is reduced
About 900,000；And when non-casting concrete, transport of the cargo ship for materials such as template, reinforcing bars, crane ship cooperation reinforcing bar,
The offshore lifting of template avoids the construction machineries work holdup phenomenon such as ship.
