Description
Technical field
The present invention relates to a kind of underwater mixed mud pouring construction methods of cloth bag water proof, belong to underwater foundation construction field.
Background technique
With the development of economy, scientific and technological progress, demand of the human society to resource are also growing.It is got in land resources
Come it is more in short supply in the case where, exploitation land occupation sphere area 70% marine resources be particularly important, ocean structure such as bridge spanning the sea,
The relevant technologies such as offshore platform, sea wall, shore protection, breakwater, seabed tunnel and man-made island also become the research hotspot of engineering circles.
The construction method of concrete placed under water is divided into cofferdam draining and does not drain two kinds.Cofferdam draining is that underwater foundation is applied
The major way of work, but the problems such as there are complicated construction technique, constructional difficulties, big displacement, construction cost, which is basically consumed in, to be enclosed
In the drainage system of weir；Drainage construction is not constructed using underwater non-dispersible concrete mainly, to meet the underwater of concrete
It is not dispersed, it needs to mix anti-dispersant in concrete.Currently used anti-dispersant generates concrete performance a series of
Adverse effect: 1) anti-dispersant and portland cement are incompatible, greatly reduce the mechanical strength of concrete；2) Mixed With Admixture
The consistency of cement slurry increases afterwards, and working performance of concrete declines to a great extent, and underwater casting is second-rate, and is easy when pumping stifled
Pipe causes to pour interruption；3) anti-dispersant is expensive causes folk prescription Cost of Concrete to increase.
Therefore, if can pour concrete and water segregation in the case where not draining, common coagulation can be used
Soil completes construction, will be with important economic significance.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of underwater mixed mud pouring construction sides of cloth bag water proof
Method guarantees the working performance of concrete, and construction is simple, save the cost when underwater casting.
To achieve the goals above, the underwater mixed mud pouring construction method of a kind of cloth bag water proof that the present invention uses, it is described
Water proof cloth bag includes the water proof cloth bag body that upper and lower side is open and the Grouting Pipe that is mounted in water proof cloth bag body, the Grouting Pipe
It being connected to the upper end opening of water proof cloth bag body, it is to have knot that can be undone by a pull line on the knot that can be undone by a pull that the lower ending opening of water proof cloth bag body, which is bundled into knot that can be undone by a pull,
The other end of knot that can be undone by a pull line is stretched out from the inside of water proof cloth bag body across Grouting Pipe；
Casing is first mounted on the bottom, then top aqueous layer and lower part coagulation will be divided into using water proof cloth bag body inside casing
Soil layer, finally by Grouting Pipe, into water proof cloth bag body, casting concrete completes construction.
Preferably, the underwater concreting construction method, comprising the following steps:
1) casing is transferred: transferring casing as required；
2) install water proof cloth bag: into water proof cloth bag body, cement injection net slurry sinks under water water proof cloth bag, when cloth bag is visited
It pulls knot that can be undone by a pull line to open the lower port of water proof cloth bag body when bottom, Grouting Pipe, coagulation is transferred simultaneously with steady rate concrete perfusion
Water proof cloth bag lower port is pushed to casing side wall by soil, forms top aqueous layer and lower part concrete layer；
3) it pours: continuing with steady rate concrete perfusion, water proof cloth bag inner concrete remains full state, coagulation
Soil pushes cloth bag and top aqueous layer mobile, and Grouting Pipe is with cloth bag hoisting depth until cloth bag is emerged horizontal plane.
Preferably, the concrete used is divergence >=700mm self-compacting concrete.
Preferably, the lower end of the water proof cloth bag body paves, area is 1.2-2 times of casing floor space.
Preferably, being equipped with threaded sleeve between the Grouting Pipe and the upper end opening of water proof cloth bag body.
The principle of the present invention is: casing inner space being divided into top aqueous layer and lower part concrete first with water proof cloth bag
Layer, suitable cement paste is then perfused into cloth bag bottoms out cloth bag, pulls knot that can be undone by a pull the end of a thread, opens the tying of cloth bag lower part,
Due to the promotion by water-in-bag cement paste, cloth bag paves to casing inner wall position, Continuous Perfusion concrete, by cloth bag and water layer
The horizontal plane until cloth bag is emerged is pushed up together.
Compared with prior art, the beneficial effects of the present invention are:
1) present invention solves the problems, such as that displacement is big in the drainage construction of cofferdam.Existing cofferdam construction needs to take out by mechanical
Water in cofferdam is discharged water, and cofferdam and draining cost are high.The present invention between concrete layer and external aqueous environment by setting
A cloth bag water barrier is set, concrete is placed in the package of water proof cloth bag and casing, concrete is avoided to connect with external aqueous environment
Touching solves the problems, such as that concrete is contacted with water and causes isolation and aggregate separated, it is ensured that do not drain the quality of pouring construction under water
Reach land and pours peer-level.
2) present invention solves the problems, such as that underwater non-dispersible workability of concrete is poor, mechanical strength is low.It is existing not drain
Underwater construction is carried out to need using underwater non-dispersible concrete, due to joined the underwater non-dispersible concrete of anti-dispersant
It is low that there are intensity, and consistency is big, problem at high cost.The present invention uses cloth bag water proof, is poured, is mentioned using self-compacting concrete
High structural strength, reduces construction cost.
