Description
Technical field
The present invention relates to the vertical lap seam technical fields of concrete face rockfill dam, and in particular to one kind avoiding concrete slab
Squeeze the vertical crack structure destroyed and construction method.
Background technology
With water power implementation, in the abundant southwest of hydraulic power potentials, the Northwest, large quantities of high dams are built, are building
Or it is yet to be built.Earth and rockfill dam is the most common type dam type and a kind of dam type with fastest developing speed in current Dam constructions, includes mainly
Homogeneous earth dam, core wall dam and concrete face rockfill dam etc..
Rock is a kind of new dam type for starting in the later stage seventies in last century to grow up, and is embodied in practice
Safety, economy, feature easy for construction and good adaptability, have developed rapidly although starting late, deep by Ba Gongjie's
Favor.With the accumulation of Dam Construction experience and the raising of design level, the height of rock is also constantly increasing,
Shuibuya Dam is up to 233m, for built highest rock in the world, also becomes the success of 250m grades of high CFRDs
Case.The gorges great Shi, thatch Ha Xia etc. proposed 250~300m grade superelevation rock is at present also in project study.
With the construction of 250~300m grades of superelevation rocks, the concrete face rockfill dam of dam emerged in operation
Seam between problem on deformation, the deformation of especially vertical pressure property seam is often larger.Vertical lap seam is using single vertical butt joint at present
Seam pattern, do not adapted to such larger deformation, this common seam pattern width cannot be excessive, excessive to hang down
Vertical masonry joint can be such that copper sheet sealing is easily damaged in panel deformation, the safety of sealing between seam be reduced, to reduce dam
Antiseepage safety, if but this common seam pattern width do not amplify, and be easy to be formed face slab rupture, thus with
The construction of superelevation rock, is badly in need of solving the double-barreled question that vertically pressure property is stitched between concrete slab, the i.e. width of vertical lap seam
Degree increases the safety of sealing between reducing seam, and width does not increase and is easy to form face slab rupture.
Invention content
The invention aims to solve the width of vertical lap seam increase reduce seam between sealing safety, width do not increase and
It is easy to be formed problem caused by face slab rupture.
To realize the above-mentioned technical purpose, the present invention is realised by adopting the following technical scheme:

Between times.
On the vertical lap seam under flank and vertical lap seam flank it is of same size, the width of vertical lap seam horizontal segment be 1.2cm ~
Between 2cm.
One or more copper sheet sealings are vertically arranged in the middle part of the vertical lap seam horizontal segment, the copper sheet sealing is by red copper material
Material is made.
The vertical backing plate of filling, the vertical backing plate are highly dense bubble in the seam of flank under flank and vertical lap seam on the vertical lap seam
Foam plate；Fill level backing plate in the seam of the vertical lap seam horizontal segment, the horizontal backing plate are rubber slab.
The surface water stop structure includes rubber bar, wave waterstop, zinc-plated expansion bolt, plastic filler, surface water stop
Plate, the bottom that the rubber bar is located at surface water stop structure are connected with the upper end of flank on vertical lap seam, and the wave waterstop is
Slab construction is located at the top of rubber bar, and wave waterstop one end is fixed on the upper table of concrete slab A by zinc-plated expansion bolt
Face, the other end are fixed on the upper surface of concrete slab B by zinc-plated expansion bolt, and the middle part of wave waterstop is waveform knot
Structure, the surface water stop plate are semicircle, completely cover entire wave waterstop, both sides have horizontal ear, horizontal ear to pass through respectively
Polyurea materials are bonded in the upper surface of concrete slab A and concrete slab B, the plastic filler be filled in surface water stop plate with
Between wave waterstop.
To achieve the goals above, the present invention also provides another technical solutions：
A kind of construction method for avoiding concrete slab from squeezing the vertical crack structure destroyed, includes the following steps：
1）Casting concrete panel A, and copper sheet sealing, copper sheet sealing one are placed in the middle part of the side horizontal segment of concrete slab A
The portion of picking up the ears is poured into concrete slab A, and completion waits for -10 days 3 days after pouring；
