Specific embodiment
The construction method of copper waterstop in a kind of CFRD seepage prevention system as shown in Figure 1 to 4, including Following steps:
Step one, copper waterstop calender 2 is lifted on bracket 5;
Step 2, by copper waterstop calender 2 and the integral hoisting of bracket 5 in the vertical of the dam crest of CFRD 1 At seam position (as shown in Figure 2);
Step 3, the reel 4 that will be wound with copper sheet raw material 3 are lifted on the roller stand 5-1 of the bracket 5;
Step 4, continuous copper waterstop 6 of colding pressing:Copper waterstop calender 2 is opened, by the copper sheet raw material 3 on the reel 4 Feeding copper waterstop calender 2, copper waterstop 6, institute are continuously cold-pressed into by the copper waterstop calender 2 by copper sheet raw material 3 Stating copper waterstop 6 includes base plate 6-1, and the both sides of the base plate 6-1 tilt to form side wing 6-2, the middle part of the base plate 6-1 The inside that upward protuberance forms protrusion 6-3, the protrusion 6-3 has cavity 6-4 (as shown in Figure 3 and Figure 4);
Step 5, filling flexible filler:The copper waterstop 6 is constantly exported from copper waterstop calender 2, and to output Copper waterstop 6 cavity 6-4 in load flexible filler, the copper waterstop 6 of populated flexible filler is along the coagulation The domatic of native rock 1 keeps falling, when the copper waterstop 6 is snapped down to the slope of the CFRD 1 During the bottom of slope in face, stop colding pressing for the copper waterstop 6.
In the present embodiment, copper sheet raw material 3 is continuously cold-pressed into by copper waterstop 6 using copper waterstop calender 2 such that it is able to Cold pressing a copper waterstop 6 long for being made and dam bottom being extended to from the dam crest of CFRD 1, and then avoid multistage Copper waterstop 6 is welded into a copper waterstop 6 long, reduces the field joint of copper waterstop 6, it is ensured that the quality of copper waterstop 6, Due to 6 cold moudling of the copper waterstop, can rapidly, continuously extrusion forming, accelerating construction progress reduces the duration.In addition, By loading flexible filler in the cavity 6-4 (being commonly called as " nasal cavity ") in copper waterstop 6, the cavity 6-4 can effectively be filled out Fill, it is to avoid the protrusion 6-3 of copper waterstop 6 is deformed after receiving external force, and be flexible filler due to what is loaded, work as Copper water stop When receiving external force with 6 protrusion 6-3, the protrusion 6-3 can have certain deformation to adapt to external force.
In the present embodiment, the flexible filler includes the He of rubber strip 7 being arranged in the cavity 6-4 of the copper waterstop 6 Foam strip 8, the rubber strip 7 is arranged on the inner side of the foam strip 8.By using 8 pairs of cavitys of rubber strip 7 and foam strip 6-4 is loaded, and effectively can be filled up the cavity 6-4, and the rubber strip 7 and the convenient material drawing of foam strip 8, price Cheaply, construction cost is saved.
In the present embodiment, in step 5, flexible filler is loaded in the cavity 6-4 to the copper waterstop 6 of output When, specifically include following steps:
Step 501, filling rubber strip 7:As shown in figure 5, rubber strip 7 is connected by the guide wheel 10 on bracket 5 Continuous to guide to the cavity 6-4 of the copper waterstop 6, the guide wheel 10 is arranged under the protrusion 6-3 of the copper waterstop 6 Side, the guide wheel 10 is in contact with the base plate 6-1 of the copper waterstop 6, band of the guide wheel 10 in the copper waterstop 6 Dynamic lower rotation;
In the present embodiment, rubber strip 7 is constantly guided to the cavity 6-4 by setting guide wheel 10, and it is described Guide wheel 10 is driven in the presence of the downslide of copper waterstop 6, it is to avoid increase drive device, and can be automatically performed rubber The filling of adhesive tape 7.
Step 502, filling foam strip 8:Foam strip 8 is loaded in the cavity 6-4 for be filled with rubber strip 7, so that The cavity 6-4 is filled up;Because the cavity 6-4 is deeper, individually foam strip 8 cannot then be filled up using rubber strip 7, and then Use foam strip 8 to be engaged with the rubber strip 7 to be filled up with by cavity 6-4.In the present embodiment, the foam strip 8 is people's frock Fill out.
The cavity 6-4 of step 503, closing copper waterstop 6:Adhesive tape 9 is bonded in the bottom of the base plate 6-1 of the copper waterstop 6 Face, so as to the cavity 6-4 closings of rubber strip 7 and foam strip 8 will be filled with.By using adhesive tape 9 by the cavity 6-4 Closing such that it is able to effectively rubber strip 7 and foam strip 8 are positioned in the cavity 6-4, it is to avoid rubber strip 7 and foam strip 8 Come off from the cavity 6-4.
In the present embodiment, when being closed to the cavity 6-4 of copper waterstop 6 using adhesive tape 9 in step 503, first will One end of adhesive tape 9 is bonded in the lower end of the copper waterstop 6, then hand-held tape roll and with the copper waterstop 6 downslide connect It is continuous to unreel adhesive tape 9, and then complete the closing of the whole cavity 6-4 of copper waterstop 6.Adopt and adhesive tape 9 is bonded in copper in this way stops Water needs people's operation with to realize the closing to the cavity 6-4, operating very easy on 6, only.
In the present embodiment, the foam strip 8 is made up of polyurethane foam.The foam strip 8 being made of polyurethane foam, valency Lattice are cheap, are easy to make.
As shown in Fig. 2 the bracket 5 includes bracket main body 5-2, the rectangular triangles of bracket main body 5-2, the support There is the inclined-plane 5-3 consistent with the dam facing gradient of CFRD 1, the copper waterstop calender 2 on frame body 5-2 It is fixedly mounted on the inclined-plane 5-3, the upper end of the bracket main body 5-2 is provided with support cushion cap 5-4, the roller stand 5- 1 is arranged on the support cushion cap 5-4.
In the present embodiment, the simple structure of the bracket 5 can realize the effective support to copper waterstop calender 2, and And before copper waterstop 6 of colding pressing, the bracket main body 5-2 is adjusted so that inclined-plane 5-3 on bracket main body 5-2 with The dam facing gradient of CFRD 1 is consistent, so that it is guaranteed that the copper waterstop calender on the inclined-plane 5-3 2 angle of inclination is consistent with the dam facing gradient of the CFRD 1, is so able to ensure that the copper of cold moudling stops Avoid producing arc on water band 6.
In the present embodiment, the copper waterstop calender 2 is using rolling type copper water stop band forming machine.
The above, is only presently preferred embodiments of the present invention, and not the present invention is imposed any restrictions, every according to the present invention Any simple modification, change and equivalent structure transformation that technical spirit is made to above example, still fall within skill of the present invention In the protection domain of art scheme.
