The method comprises the steps of installing, using, removing and the like. The joint and the method have the beneficial effects that the operation is simple, convenient and practical, soil sources of the sand bags are rich, the streaming-around preventing effect of the sand bags is good, the sand bags can be processed conveniently, construction procedures of a diaphram wall can be reduced by using a backfill sand bag streaming-around preventing technology, a joint box can not be installed and be propped and pulled, the cost is reduced, the working efficiency is improved, the construction quality of the diaphram wall is ensured, and the seepage-proofing effect of the diaphram wall is good.
Description
Technical field
The present invention relates to the constructing tunnel field, relate in particular to the anti-method of streaming of a kind of diaphragm wall iris type joint and concreting thereof.
Background technology
At present, resolving the underground continuous wall connector connectivity problem in China, is the difficult point that underground continuous wall construction technique further develops, and also is the emphasis of research.The underground continuous wall connector situation that is adopted at present is a lot, and wherein the iris type joint is exactly wherein a kind of.The iris type joint mainly comprises H shape dividing plate and V-arrangement dividing plate.The slit is arranged between construction of diaphragm wall median septum and cell wall unavoidably, and concrete is easy to produce and streams, and generally is employed in and inserts the concrete that the joint case comes shutoff to stream in the dividing plate.Construction one is time of pulling out of rising of joint case to be difficult to control like this.Pull out too early if rise, concrete also is in flow regime, and the joint case is prevented streaming just inoperative; Pulled out evening if rise, concrete will be glued together with the joint case, caused and pulled out difficulty.The 2nd, install and rise and pull out the joint case and need call large-scale crane and driver-extractor, and the engineering time is long.The 3rd, the joint case can not thoroughly solve anti-circumferential motion problem, the phenomenon on the local limit of collapsing particularly when running into layer of sand, occurs, and concrete streams very serious.
Summary of the invention
The purpose of this invention is to provide the concreting of a kind of diaphragm wall iris type joint and prevent streaming method, to solve the problem that runs in the above-mentioned constructing tunnel.
The object of the invention is realized through following technical scheme:
A kind of diaphragm wall iris type joint comprises reinforcing cage and iris type joint, and said reinforcing cage two ends are connected with the iris type joint, and the reinforcing cage both sides are provided with baffle plate, is provided with sandbag between said iris type joint and the metope.
Further, said iris type joint can adopt H shape dividing plate joint or V-arrangement dividing plate joint.
The concreting of above-mentioned diaphragm wall iris type joint is anti-streams method, may further comprise the steps:
1) uses the crane lifting reinforcing cage, and the iris type joint is connected with reinforcing cage;
2) build the first phase groove, also extract mud simultaneously out at both sides, iris type joint outside backfill simultaneously sandbag;
3) build the second stage of groove, backfill sandbag in concreting makes that concrete rising speed is consistent with sandbag rising speed and extracts mud simultaneously out;
4) build and finish, during excavation adjacent slot section, use groover that sandbag is dug out, and use brush wall device that the iris type inner nosepiece wall is washed away totally.
Further, said iris type joint adopts H shape dividing plate joint or V-arrangement dividing plate joint.
Beneficial effect of the present invention is: simple, convenient, practical, the Tu Yuan of sandbag is abundant, and sandbag is prevented streaming effective; The processing sandbag is convenient; The anti-technology of streaming of backfill sandbag has reduced the construction of continuous concrete wall operation, need not install and pull the joint case, has not only reduced cost but also improved operating efficiency; And guaranteed the construction of continuous concrete wall quality, made the anti-seepage effect of diaphragm wall better.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the structural representation of the described a kind of diaphragm wall iris type joint of the embodiment of the invention;
Fig. 2 is the structural representation vertical view of a kind of diaphragm wall iris type joint of the described employing of embodiment of the invention H type dividing plate joint;
Fig. 3 is the structural representation vertical view of a kind of diaphragm wall iris type joint of the described employing V-type dividing plate joint of the embodiment of the invention.
Among the figure:
1, reinforcing cage; 2, baffle plate; 3, iris type joint; 4, sandbag; 5, H type dividing plate joint; 6, V-type dividing plate joint.
The specific embodiment
Shown in Fig. 1-3; The described a kind of diaphragm wall iris type joint of the embodiment of the invention comprises reinforcing cage 1 and iris type joint 3, and said reinforcing cage 1 two ends are connected with iris type joint 3; Reinforcing cage 1 both sides are provided with baffle plate 2, are provided with sandbag 4 between said iris type joint 3 and the metope; Said iris type joint 3 can adopt H shape dividing plate joint 5 or V-arrangement dividing plate joint 6.
The concreting of the described a kind of diaphragm wall iris type joint of the embodiment of the invention is anti-streams method, may further comprise the steps:
1) uses crane lifting reinforcing cage 1, and iris type joint 3 is connected with reinforcing cage 1;
2) build the first phase groove, the sandbag of backfill simultaneously 4 is also extracted mud simultaneously out on both sides, iris type joint 3 outside;
3) build the second stage of groove, backfill sandbag 4 in concreting makes that concrete rising speed is consistent with sandbag 4 rising speed and extracts mud simultaneously out;
4) build and finish, during excavation adjacent slot section, use groover that sandbag 4 is dug out, and use brush wall device that iris type joint 3 inwalls are washed away totally.
During practical implementation, at first adorn sandbag, the earthwork that sandbag adopts continuous wall trench underground to dig out with soil; Then hang iris type joint reinforcing cage; And interim baffle plate is installed on iris type joint top, and prevent that sandbag from falling in the reinforcing cage, be transported to the job site to the sandbag that installs then; Be exactly the backfill sandbag at last; If first phase groove backfill sandbag needs both sides symmetry backfill,, otherwise can cause the sandbag of backfill to squeeze inclined to one side phenomenon appearance to reinforcing cage if the height of the second stage of groove sandbag backfill slowly raises with the concrete spouting height.Need pump drainage mud during the backfill sandbag, prevent that mud from overflowing groove and causing environment pollution outward.When excavation adjacent slot section, sandbag is dug out by groover, and cleans out the iris type inner nosepiece wall with brush wall device, guarantees the construction of diaphragm wall quality.
The present invention has verified its service behaviour through the practical application at station, Zhengzhou City's track traffic Line 1 first phase civil works conference and exhibition center.Simple, convenient and practical, practiced thrift engineering cost, be applicable to that similar diaphragm wall iris type joint handles, employing is worthy to be popularized.
Though below only described specific embodiment example of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the following claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes or modification all fall into protection scope of the present invention.
