Abstract
The invention discloses the syndeton of a kind of barrage foundation diaphragm wall and gate dam building, comprise seepage prevention and gate dam building; Highly foaming polyethylene plate and precast concrete frid is disposed with from bottom to top between the end face of seepage prevention and gate dam building; Gap is provided with between seepage prevention and the surface, seepage prevention upstream and downstream of gate dam building junction, bury " U " type Copper water stop in the middle part of the gap of upstream side underground, the sealing piece of " U " type Copper water stop nose both sides respectively correspondence extends in seepage prevention and gate dam building; Be provided with neoprene rod in sealing nasal cavity, the gap being positioned at sealing nose top is filled with polysulfide sealant, and the gap being positioned at sealing nose bottom is filled with high pressure closed-cell polyvinylchloride plate; In the gap in downstream, be filled with high pressure closed-cell polyvinylchloride plate, the top in gap, downstream is filled with polysulfide sealant.The invention has the advantages that structure is simple, adapt to the distortion of gate dam base, sealing connection is reliable.
Description
Technical field
The present invention relates to barrage in Hydraulic and Hydro-Power Engineering, especially relate to the syndeton of barrage foundation diaphragm wall and gate dam building.
Background technology
In water conservancy and hydropower dam project, when channel sand cobble covering layer is darker or retaining box dam, relative ground building is lower, Foundation Anti-seepage often adopts impervious wall form.Because gate dam exists the distortion such as sedimentation, displacement in construction with in running, therefore the connection of impervious wall and dash gate dam is most important, once there is craze and transfiguration in connecting portion, water slop failure, leakage passage will be formed at gate dam foundation, cause gate dam foundation generation seepage failure, jeopardize the safety of 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 gate dam building, can close again the barrage foundation diaphragm wall of sealing and the syndeton of gate dam building.
For achieving the above object, the present invention takes following technical proposals:
The syndeton of barrage foundation diaphragm wall of the present invention and gate dam building, comprises seepage prevention and gate dam building; Highly foaming polyethylene plate and precast concrete frid is disposed with from bottom to top between the end face of described seepage prevention and gate dam building; Gap is provided with between seepage prevention and the surface, seepage prevention upstream and downstream of gate dam building junction, in the middle part of the gap being positioned at described upstream side, bury " U " type Copper water stop underground, the sealing piece of the sealing nose both sides of described " U " type Copper water stop respectively correspondence extends in seepage prevention and gate dam building; In described sealing nasal cavity, be provided with neoprene rod, the gap being positioned at sealing nose top is filled with polysulfide sealant, and the gap being positioned at sealing nose bottom is filled with high pressure closed-cell polyvinylchloride plate; Be filled with high pressure closed-cell polyvinylchloride plate in the gap being positioned at described downstream, the top in gap, downstream is filled with polysulfide sealant.
Described seepage prevention is made up of the slotted eye impervious wall of bottom and the cast-in-situ steel reinforced concrete impervious wall on top; The contact surface of seepage prevention upstream and downstream and described riverbed concrete cushion is coated with bitumen layer respectively.
The invention has the advantages that structure is simple, adapt to the distortion of gate dam base, sealing connection is reliable; Construction technology is easy to implement simultaneously, invests relatively low.Be arranged on the highly foaming polyethylene plate of seepage prevention end face, meet the needs of gate dam base sedimentation and deformation.The gap being positioned at described sealing nose bottom is filled with high pressure closed-cell polyvinylchloride plate, meets dam foundation displacement, torsional deflection requirement, and in gap, sealing nose top, filling polysulfide sealant is used for preventing around oozing.High pressure closed-cell polyvinylchloride plate is loaded in the gap being positioned at described downstream, and to adapt to the needs of dam foundation displacement, torsional deflection, its top filling polysulfide sealant plays further and prevents around the effect of oozing.
