Abstract
The utility model discloses a connecting structure of a barrage foundation diaphragm wall and a gate dam building. The connecting structure comprises the foundation diaphragm wall, the gate dam building and a riverbed concrete cushion layer. A high-foaming polyethylene plate and a precast concrete trough plate are arranged between the top face of the foundation diaphragm wall and the gate dam building from bottom to top in sequence. Clearances are arranged between the upstream surface and the downstream surface of the foundation diaphragm wall of the connecting position of the foundation diaphragm wall and the gate dam building, a U-shaped copper water stop is buried in the middle of the clearance of the upstream side, and water stop pieces on the two sides of the water stop nose of the U-shaped copper water stop respectively extend to the inner portion of the foundation diaphragm wall and the inner portion of the gate dam building. A chloroprene rubber bar is arranged in the cavity of the water stop nose, polysulfide sealants are filled in the clearance in the upper portion of the water stop nose, and a high-pressure hole closing polyvinyl chloride plate is filled in the clearance in the lower portion of the water stop nose. A high-pressure hole closing polyvinyl chloride plate is filled in the clearance of the downstream side, and polysulfide sealants are filled in the top portion of the clearance of the downstream side. The connecting structure of the barrage foundation diaphragm wall and the gate dam building has the advantages of being simple in structure, adapting to deformation of a gate dam foundation and being reliable in water stop connection.
Description
Technical field
The utility model relates to barrage in the Hydraulic and Hydro-Power Engineering, especially relates to the syndeton of barrage basis impervious wall and gate dam building.
Background technology
In the water conservancy and hydropower dam project, when retaining box dam, the darker or relative ground of channel sand cobble covering layer building was low, the impervious wall form was often adopted in basic antiseepage.Because gate dam is in construction and in servicely have distortion such as sedimentation, displacement, therefore impervious wall is most important with being connected of dash gate dam, in case craze and transfiguration appears in connecting portion, sealing lost efficacy, will form leakage passage at gate dam foundation, cause gate dam foundation generation seepage failure, the safety that jeopardizes the gate dam building.
Summary of the invention
The utility model purpose is to provide a kind of sedimentation and deformation that can adapt to the gate dam building, can seal the barrage basis impervious wall of sealing and the syndeton of gate dam building again.
For achieving the above object, the utility model is taked following technical proposals:
The syndeton of barrage basis impervious wall described in the utility model and gate dam building comprises basic impervious wall, gate dam building and riverbed concrete cushion; Be disposed with highly foaming polyethylene plate and precast concrete frid between the end face of described basic impervious wall and the gate dam building from bottom to top; Between the surface, basic impervious wall upstream and downstream of basic impervious wall and gate dam building junction, be provided with the slit, bury " U " type Copper water stop underground at the middle part, slit that is positioned at described upstream side, the sealing sheet of the sealing nose both sides of described " U " type Copper water stop correspondence respectively extends in basic impervious wall and the gate dam building; Be provided with the neoprene rod in described sealing nasal cavity, the slit that is positioned at sealing nose top is filled with polysulfide sealant, and the slit that is positioned at sealing nose bottom is filled with high pressure closed pore polyvinyl chloride panel; Be filled with high pressure closed pore polyvinyl chloride panel in the slit that is positioned at described downstream, the top in slit, downstream is filled with polysulfide sealant.
Described basic impervious wall is made of the slotted eye impervious wall of bottom and the cast-in-situ steel reinforced concrete impervious wall on top; On the contact surface of basic impervious wall upstream and downstream and described riverbed concrete cushion, be coated with bitumen layer respectively.
The utility model advantage is simple in structure, adapts to the distortion of gate dam base, sealing connection reliably; Construction technology is easy to implement simultaneously, invests relatively low.Be arranged on the highly foaming polyethylene plate of basic impervious wall end face, satisfied the needs of gate dam base sedimentation and deformation.The slit that is positioned at described sealing nose bottom is filled with high pressure closed pore polyvinyl chloride panel, has satisfied dam foundation displacement, torsional deflection requirement, and the filling polysulfide sealant is used for preventing around oozing in the slit, sealing nose top.High pressure closed pore polyvinyl chloride panel is loaded in the slit that is positioned at described downstream, and to adapt to the needs of dam foundation displacement, torsional deflection, its top filling polysulfide sealant further plays and prevents around the effect of oozing.
