Description
Technical field
The utility model relates to water distribution structure in a kind of immersed tube engineering, relates in particular to a kind of immersed tube tunnel joint waterproof construction.
Background technology
Immersed tube tunnel is that the pipeline section prefabricated in the location, depressed place consigned section by section to satisfying location, carries out underwater mating after the sinking contraposition section by section, and tunnel joint is the significant points of immersed tube tunnel, is also weak part simultaneously, and the joint waterproofing between pipeline section and pipeline section is very important.Because the service life of immersed tube tunnel is longer, be generally about 100 years, can reach effective purpose within service life in order to guarantee the tunnel joint waterproof, how to guarantee the tunnel joint waterproof quality, become to be directly connected to the operation of immersed tube tunnel.
In the tunnel joint waterproof, the much more general mixture that adopts butadiene-styrene rubber and natural rubber be the GINA waterstop made of material as first road waterproof construction, therefore, the GINA waterstop is Joints in Immersed Tunnel water-tight and safe important barrier.The GINA Water stop structure is by middle with hole and bottom, middle all two kinds of forms with holes, and profile is also divided strip and frame type.The installation of GINA waterstop is fixed and has also been divided several methods.After the immersed tube sinking puts in place, due to the inhomogeneous sinking of pipeline section, can make GINA waterstop unbalance stress, thereby cause local damage or local apart from holding box hat to come off, thereby lose the effect of first road sealing.
The utility model content
For above-mentioned prior art, in order to guarantee that the tunnel joint waterproof can reach effective purpose within service life, incorporation engineering environmental geography condition, reference is the constructing tunnel experience in the past, the utility model provides a kind of immersed tube tunnel joint waterproof construction of the GINA of having waterstop, have and install simply, be applicable to the pipeline section base fixed, settling amount is little, water body has corrosive characteristics.
In order to solve the problems of the technologies described above, the utlity model has the technical scheme that the immersed tube tunnel joint waterproof construction of GINA waterstop is achieved is: the steel end housing that comprises the tunnel joint place, be provided with a circle GINA waterstop along described end box hat peripheral side, described GINA waterstop and described end box hat fit tightly, on described end box hat, and the both sides that are positioned at described GINA waterstop lower limb are welded with respectively the waterstop briquetting, be overlapped with a waterstop pressing plate above described waterstop briquetting, described waterstop pressing plate compresses GINA waterstop and waterstop briquetting by threaded fastener simultaneously.
The utlity model has the immersed tube tunnel joint waterproof construction of GINA waterstop, wherein, the surface of described waterstop briquetting, described waterstop pressing plate is equipped with the electric arc zn spraying anticorrosive coat.Described threaded fastener comprises hexagon socket cap head screw and spring washer, and described hexagonal cylindrical head screw and spring washer all adopt stainless steel.
Compared with prior art, the beneficial effects of the utility model are:
The utility model tunnel joint waterproof construction, it is simple in structure, and the construction period is short, adopts through antiseptic waterstop briquetting and pressing plate, can further guarantee to extend the application life of waterstop in the seawater corroded for a long time.Through experimental use, from the waterstop drawing, to the sealing stage at initial stage, waterproof construction of the present utility model can well guarantee the stagnant water effect at immersed tube tunnel joint place, and the water of joint is drained very soon.
The accompanying drawing explanation
Fig. 1 is the cross-sectional drawing of immersed tube tunnel joint;
Fig. 2 is the immersed tube tunnel joint waterproof construction sectional drawing that has the GINA waterstop in Fig. 1 shown in I-I.
In figure:
1-pipeline section base plate 2-end box hat 3-GINA waterstop 4-external wall
5-pipeline section top board 6-waterstop briquetting 7-waterstop pressing plate 8-spring washer
The 9-hexagon socket cap head screw.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, the joint of immersed tube pipeline section is by pipeline section base plate 1, pipeline section top board 5 and external wall 4 enclose formation, a kind of immersed tube tunnel joint waterproof construction with GINA waterstop of the utility model, the steel end housing 2 that comprises the tunnel joint place, be provided with a circle GINA waterstop 3 along described end box hat 2 peripheral side, described GINA waterstop 3 fits tightly with described end box hat 2, on described end box hat 2, and the both sides that are positioned at described GINA waterstop 3 lower limbs are welded with respectively waterstop briquetting 6, be overlapped with a waterstop pressing plate 7 above described waterstop briquetting 6, described waterstop briquetting 6, the surface of described waterstop pressing plate 7 is equipped with the electric arc zn spraying anticorrosive coat, described waterstop pressing plate 7 compresses GINA waterstop 3 and waterstop briquetting 6 by threaded fastener simultaneously, described threaded fastener comprises hexagon socket cap head screw 9 and spring washer 8, and described hexagonal cylindrical head screw 9 and spring washer 8 all adopt stainless steel Cr18Ni9Ti material.
The process that forms the immersed tube tunnel joint waterproof construction of the GINA of having waterstop of the present utility model in construction is: when immersed tube pipeline section reinforced concrete construction completes, after the inner slip casting of end box hat, carry out the installation of GINA waterstop 3.At first, welding waterstop briquetting 6 on end box hat 2, this waterstop briquetting 6 is to do the electric arc zn spraying preservative treatment after the bloom derusting by sandblasting; The installation of GINA waterstop 3, at first find hoisting point position, then fastens suspension centre, once lifts; By installation in position after 7 preservative treatments of waterstop pressing plate, padded spring washer 8 and tightened hexagon socket cap head screw 9.
