Abstract
The seepage control system that plastic concrete cut-off wall and Reinforced Concrete Retaining Walls are combined, its structure include core, the reinforcing of three axes agitating pile cell wall, plastic concrete cut-off wall, Reinforced Concrete Retaining Walls, fill sand long tube bag.Seepage prevention system of the present invention can be in flood season rapid construction, and can guarantee that the combination against seepage system of anti-seepage effect.
Description
Technical field
The present invention relates to the seepage control system that a kind of plastic concrete cut-off wall and Reinforced Concrete Retaining Walls are combined, belong to work
Journey construction field.
Background technology
Hong Gu tunnels Dong An cofferdam in Nanchang City are that termination monoblock type both sides separate type fills sand long tube sack cofferdam, and it is wide that weir crest sets 8m
Emergency Access, cope level 23.70m, Bottom Altitude 2.0m, weir body height about 21.7m.Cofferdam inslope slope ratio
Respectively 1：2、1:2.5 and 1:2.5, outside side slope is respectively 1:2.5、1:2.5 and 1:3.0, respectively in 18.5m elevations and
10.0m elevations set plain stage of slope.Weir body below 18.2m elevations sets plastic concrete diaphragm wall as antiseepage structure body, and 18.2m~
The external side in 23.7m elevation scopes weir is clay core sloping core, and inner side is to fill sand long tube bag.
Influenceed by ship migration hysteresis in the range of cofferdam, cofferdam goes into operation serious hysteresis, and in April, 2015 is Nanchang Ganjiang River
The spring flood that water level rises suddenly and sharply, on the occasion of rainy season in peach blossom flood season construction 18.2m elevation above Clay Microstructures and long tube bag back-up sand,
According to working procedure arrangement, sand long tube bag is filled on the inside of first construction cofferdam, after treating its construction, is constructed filling above sand long tube bag
Interim sidewalk, then carry out clay core sloping core on the outside of cofferdam and fill.The back-up sand of long tube bag construct when, using hydraulic pressure hydraulic giant by water with
Sand presses 1:0.75 mixing pulping, then extracts mixing slurry filling using slush pump, and sand is consolidated into bleeding in long tube bag
Rib body.
Former Jiangxi east embankment has been removed in foundation pit enclosure structure construction in Hong Gu tunnels Dong An cofferdam, and cofferdam is first of flood control body
System, it is necessary to cofferdam construction is completed before the rise of spring flood water level, it is ensured that Nanchang old town flood control safety.Clay core sloping core
Clay core sloping core can not be filled completion on the occasion of rainy season by construction before flood season arrives, and compaction quality can not meet it is impervious
It is required that cofferdam will be unable to meet that flood control requires, on the one hand huge potential safety hazard will be caused to Nanchang old town people's lives and properties,
The opposing party is flushing, and paddy tunnel will be unable to complete on schedule.
The content of the invention
The purpose of the present invention is to provide a kind of plastic concrete cut-off wall and armored concrete gear for prior art deficiency
The seepage control system that wall is combined, can be in flood season rapid construction, and can guarantee that the combination against seepage system of anti-seepage effect, i.e., a kind of plasticity
The seepage prevention system that concrete cut and Reinforced Concrete Retaining Walls are combined.
System architecture of the present invention is mixed including core, the reinforcing of three axes agitating pile cell wall, plastic concrete cut-off wall, reinforcing bar
Coagulate native barricade, fill sand long tube bag；
The plastic concrete cut-off wall top surface sets three axes agitating pile cell wall to reinforce to both sides, and three axes agitating pile cell wall adds
Gu both sides set core, core both sides, which are set, fills sand long tube bag；
Reinforced Concrete Retaining Walls are set at the top of the plastic concrete cut-off wall, and Reinforced Concrete Retaining Walls are set behind fills sand
Long tube bag, Reinforced Concrete Retaining Walls and plastic concrete cut-off wall joint part dabbing, ensure construction joint waterproof quality；
Below plastic concrete cut-off wall top surface, first construct and core and fill sand long tube bag, then three axes agitating pile groove of constructing
Wall is reinforced, plastic concrete cut-off wall of finally constructing；Cut-pff wall certain depth is removed using excavator or artificial chisel, is easy to construction steel
Reinforced concrete barricade tenon；During construction reinforced bar concrete guard wall, Reinforced Concrete Retaining Walls set one of movement joint at a certain distance,
Movement joint position sets rubber watertight strip；Sand long tube bag and its side slope protection are filled in construction to Reinforced Concrete Retaining Walls behind.
Beneficial effects of the present invention:Seepage control system of the present invention can be in flood season rapid construction, and can guarantee that anti-seepage effect.
Brief description of the drawings
Fig. 1 is that a kind of plastic concrete cut-off wall+Reinforced Concrete Retaining Walls are combined seepage control system drawing in side sectional elevation；
In figure：1. the reinforcing of core, 2. three axes agitating pile cell walls, 3. plastic concrete cut-off walls, 4. Reinforced Concrete Retaining Walls,
5. fill sand long tube bag.
Embodiment
System architecture of the present invention is mixed including core, the reinforcing of three axes agitating pile cell wall, plastic concrete cut-off wall, reinforcing bar
Coagulate native barricade, fill sand long tube bag；
The seepage control system that the present invention is combined for plastic concrete cut-off wall and Reinforced Concrete Retaining Walls, 18.2m elevations with
Upper clay core sloping core and its behind fill sand long tube bag and are adjusted to Reinforced Concrete Retaining Walls+fill sand long tube bag, armored concrete gear
Wall plan-position is located at the top of plastic concrete cut-off wall, two kinds of concrete joint part dabbings, ensures construction joint waterproof quality.
The seepage control system operational procedure is as follows:
1st, the construction core of both sides below plastic concrete cut-off wall top surface and three axles stirring of constructing again is filled after sand long tube bag
Stake cell wall is reinforced, plastic concrete cut-off wall of finally constructing；
2nd, cut-pff wall 500mm is removed using excavator and artificial chisel, is easy to construction reinforced bar concrete guard wall tenon.
3rd, during construction reinforced bar concrete guard wall, barricade sets one of movement joint every 12m, and movement joint position sets steel side rubber and stopped
Water band.
4th, sand long tube bag and its side slope protection are filled in construction to Reinforced Concrete Retaining Walls behind.
