Abstract
The invention discloses a connection structure of a barrage foundation diaphragm wall and a gate dam building, which comprises the foundation diaphragm wall and the gate dam building, wherein a high foaming polyethylene plate and a precast concrete trough plate are sequentially arranged between the top surface of the foundation and the gate dam building from top to bottom; gaps are arranged between the surfaces of the upstream and the downstream at the joint of the foundation diaphragm wall and the gate dam building respectively; U-shaped copper water stop is buried in the middle of the gaps on the upstream side; water stop strips on the two sides of a water stop nose of the U-shaped copper water stop are correspondingly extends into the foundation diaphragm wall and the gate dam building respectively; a neoprene rod is arranged the cavity of the water stop nose; polysulfide sealant is filled in the gaps positioned at the upper part of the water stop nose; high pressure blind hole polyvinyl chloride panels are filled in the gaps positioned at the lower part of the water stop nose; high pressure blind hole polyvinyl chloride panels are filled in the gaps on the downstream side; and polysulfide sealant is filled at the top of the gaps of the downstream side. The connection structure has the advantages of simple structure, suitability for deformation of a gate dam base and reliability in water stopping and connection.
Description
Technical field
The present invention relates to barrage in the Hydraulic and Hydro-Power Engineering, especially relate 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 object of the invention 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 present invention takes following technical proposals:
The syndeton of barrage basis impervious wall of the present invention and gate dam building comprises basic impervious wall and gate dam building; 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 invention has the advantages that simple in structurely, adapt to the distortion of gate dam base, sealing connects reliable; 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 to prevent 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.
