Abstract
The utility model relates to a kind of joint design of composite water-stop.The purpose of this utility model is to provide a kind of joint design of composite water-stop, with the connecting portion of all side seam middle part sealings of reinforced panel and panel vertical lap seam bottom waterstop, improves seepage control of dam stagnant water effect.The technical solution of the utility model is: a kind of joint design of composite water-stop, comprise steel concrete panel, toe board, all side seams, all side seam base copper sealings, all side seams middle part PVC waterstop, peripheral joint surface plastic sealing, vertical lap seam base copper sealing and vertical lap seam surface plasticity sealing, wherein all side seam base copper sealings and vertical lap seam base copper sealing are W type copper seal, on vertical lap seam base copper sealing, weld a square copper band to form open-topped copper sheathing, copper sheathing open top is horizontal plane; Described all side seams middle part PVC waterstop stretches to the bottom of copper sheathing, and pours into heated bitumen in the space surrounding at copper sheathing, and pitch note is to finishing apart from copper sheathing open top face 2cm.
Description
Technical field
The utility model relates to a kind of joint design of composite water-stop.Be applicable to the engineerings such as high concrete panel loose rock dam.
Background technology
The seepage prevention system of Concrete Face Rockfill Dam is the lifeline that ensures dam safety, and between position, riverbed toe board and panel the residing elevation of all side seams compared with low, to bear hydraulic pressure large, after existing sealing to lose efficacy, be difficult to the features such as reparation, therefore this position periphery fissure waterstop reliability of structure just seems particularly crucial.In Practical Project, high dam week side seam operated by rotary motion surface, middle part and bottom three road sealings; Panel vertical lap seam operated by rotary motion surface and bottom twice sealing.Peripheral joint surface sealing, bottom waterstop are connected with vertical lap seam surface water stop, bottom waterstop respectively like this, and all side seams middle part sealing is connected with vertical lap seam bottom waterstop again in addition, to form the sealing system of sealing.It is generally that same material connects that panel periphery seam is connected with surface water stop, the bottom waterstop of panel vertical lap seam, and technical maturity is reliable; And panel periphery seam middle part sealing is generally the connection of foreign material, different in nature structure with being connected of panel vertical lap seam bottom waterstop, after general employing hot pressing, rivet at present, as deal with improperly, easily become the weak part of sealing system, be unfavorable for seepage control of dam stagnant water effect.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of joint design of composite water-stop is provided, with the connecting portion of all side seam middle part sealings of reinforced panel and panel vertical lap seam bottom waterstop, improves seepage control of dam stagnant water effect.
The technical scheme that the utility model adopts is: a kind of joint design of composite water-stop, comprise steel concrete panel, toe board, all side seams, all side seam base copper sealings, all side seams middle part PVC waterstop, peripheral joint surface plastic sealing, vertical lap seam base copper sealing and vertical lap seam surface plasticity sealing, wherein all side seam base copper sealings and vertical lap seam base copper sealing are W type copper seal, it is characterized in that: on vertical lap seam base copper sealing, weld a square copper band to form open-topped copper sheathing, copper sheathing open top is horizontal plane; Described all side seams middle part PVC waterstop stretches to the bottom of copper sheathing, and pours into heated bitumen in the space surrounding at copper sheathing, and pitch note is to finishing apart from copper sheathing open top face 2cm.
Described copper sheathing bottom is 5-6cm along the length of panel vertical lap seam, and copper sheathing width is than all side seams middle part PVC sealing bandwidth 1-2cm, and copper sheathing height is got the half that position concrete slab thickness is set.
The beneficial effects of the utility model are: adopt after this water-stopping joint structure, preferably resolve being connected of all side seams middle part PVC waterstop and panel vertical lap seam base copper sealing, improve seepage control of dam stagnant water effect, for some reference provides successful technical experience.
Brief description of the drawings
Fig. 1 is the structure chart that the utility model band is analysed and observe.
Detailed description of the invention
As shown in Figure 1, the present embodiment comprises steel concrete panel 1, toe board 2, all side seams 3, all side seam base copper sealings 4, all side seams middle part PVC waterstop 5, peripheral joint surface plastic sealing 6, vertical lap seam base copper sealing 7 and vertical lap seam surface plasticity sealing 8, and wherein all side seam base copper sealings 4 and vertical lap seam base copper sealing 7 are W type copper seal.This routine feature is, adopts copper seal to make a rectangular copper band, is placed on vertical lap seam base copper sealing 7, and weld with vertical lap seam base copper sealing 7 copper band bottom, forms open-topped copper sheathing 9, and copper sheathing open top is horizontal plane.All side seams middle part PVC waterstop 5 is stretched to the bottom (being the top of the middle nose of vertical lap seam base copper sealing 7W type copper seal) of copper sheathing 9, then in the space surrounding to copper sheathing 9 with funnel, pour into heated bitumen 10, pitch note is to finishing apart from copper sheathing open top face 2cm.After pitch is cooling, form the jointing of all side seams middle part PVC waterstop 5 and copper sheathing 9 sealings.
In this example, copper sheathing 9 bottoms should not be greater than 6cm along the length of panel vertical lap seam, and copper sheathing width is than all side seams middle part PVC waterstop 5 slightly wide 1-2cm, and copper sheathing height is got the half that position concrete slab thickness is set.
