Technical field
The utility model relates to hydro project technical field, specifically refers to that a kind of dam facing reconstruct concrete anti-seepage panel erects to double-deck water sealing structure.
Background technology
Concrete anti-seepage panel is the main seepage prevention of upstream dam facing, one of main problem that its safe reliability Shi Ba work circle is paid close attention to always. When the concrete anti-seepage panel of upstream, main dam exists the defects such as crack, dew muscle, honeycomb, hole and analysis calcium, it leaks seriously, now needs reconstruct reinforcing anti-seepage panel. At present, when similar masonry gravity dam is carried out anti-seepage reinforcing by China, concrete anti-seepage panel and water seepage prevention system is generally reconstructed at upstream dam facing, although reaching antiseepage object, but there is following defect in it: it is one years old, reconstruct water seepage prevention system does not make full use of and in conjunction with original water seepage prevention system, and the mode of point seam sealing many employings individual layer sealing of face slab for water retaining, and its sealing reliability affects bigger by sealing material quality and operating technique level; Its two, if in construction there is undiscovered defect in the welded and installed of sealing piece, the sealing reliability of face slab for water retaining will be difficult to ensure; Its three, erecting of masonry gravity dam reconstruct is staggered to point seam and erecting of former dam body to a point seam, forms the fissure of displacement, can cause like this reconstructing the deformation of face slab for water retaining with original face slab for water retaining so that reconstruct face slab for water retaining and easily produce crack.
Summary of the invention
The purpose of this utility model is to provide a kind of dam facing reconstruct concrete anti-seepage panel to erect to double-deck water sealing structure, newly erecting of its novel concrete face slab for water retaining can adapt to the distortion of original concrete anti-seepage panel to a point seam, avoid reconstruct concrete anti-seepage panel cracking, and make full use of and in conjunction with original water seepage prevention system, formation is erected to double-deck water sealing structure, it is ensured that the stagnant water effect of reconstruct concrete anti-seepage panel.
For achieving the above object, the utility model is by the following technical solutions: the utility model dam facing reconstruct concrete anti-seepage panel erects to double-deck water sealing structure, comprise the reconstruct concrete anti-seepage panel being made up of original concrete anti-seepage panel and novel concrete face slab for water retaining, inorganic interface assembly glue it is provided with between described original concrete anti-seepage panel and described novel concrete face slab for water retaining, described original concrete anti-seepage panel comprises former erecting and stitches to dividing, described novel concrete face slab for water retaining comprise newly erect to point seam, its special character is: described original concrete anti-seepage panel is provided with three chamfered grooves former erecting to a point seam outside cutter, the contact surface brushing SR primer of described three chamfered grooves, SR plastic filler is filled in described three chamfered grooves, described original concrete anti-seepage panel is provided with SR lid sheet to form SR sealing piece above three chamfered grooves,Described newly erecting forms logical seam to point seam and former erecting to a point seam; Described newly erect to point seam in filled polyethylene high pressure closed-cell foam plate, described newly erect to point seam copper water stop is also installed.
Preferably, described SR lid sheet is fixed on described original concrete anti-seepage panel by steel press strip and expansion bolt.
Further, the width of described three chamfered grooves is 12cm, and the degree of depth is 5cm.
Again further, described newly erect to point seam a width be 2cm.
Again further, the thickness of described copper water stop is 1.0mm; The sealing nose vertical section height of described copper water stop is 4.5cm, and the width of described sealing nose is 3.5cm.
The beneficial effects of the utility model are:
Its one, what the utility model adopted that SR sealing piece and copper water stop combine erects to double-deck water sealing structure, and it has anti-seepage effect more better than prior art.
They are two years old, of the present utility model newly erecting forms logical seam to point seam and former erecting to a point seam, the distortion of dam body can be adapted to like this, the distortion of novel concrete face slab for water retaining and original concrete anti-seepage panel can be coordinated, reconstruct concrete anti-seepage panel cracking can be avoided, it is ensured that the stagnant water effect of reconstruct concrete anti-seepage panel.
Its three, the utility model makes full use of original concrete anti-seepage panel, erects original concrete anti-seepage panel former and forms a SR sealing piece to a point seam outside. Construction volume can be reduced like this, reduce engineering cost.
