Description
Technical field
The present invention relates to a kind of insulation quilt for severe cold cold weather concrete dam and mounting method and device, belong to Hydraulic and Hydro-Power Engineering technical field, specifically belong to the dam concrete temperature control technology field in Hydraulic and Hydro-Power Engineering.
Background technology
At present, according to domestic severe cold area Concrete Dam Construction temperature control measures, when concrete construction, after general employing concrete removal masterplate, in the measure of concrete surface laying insulation quilt, concrete is incubated, but the process of deployment of Practical Project dam body upstream and downstream face insulation quilt is comparatively loaded down with trivial details, adjacent insulation quilt does not connect into entirety, insulation quilt needs to adopt firm rack that insulation quilt is fixed after having laid, the construction method of this installation insulation quilt not only difficulty of construction is large, also has larger danger simultaneously.
Chinese patent literature publication number is in the data of CN1837490A, to disclose a kind of " concrete external insulation method for hydraulic engineering ", and the method is to play insulation effect by warming plate adhesive is attached to concrete surface.Concrete steps comprise basic unit's face processing, warming plate cloth glue, warming plate stickup, paste post processing and warming plate polishing etc.This heat preserving method, by adopting adhesive that warming plate is sticked on treated concrete base layer face, warming plate and basic unit's face firm pasting, neat, heat insulation effect is good.But this heat preserving method is had relatively high expectations to the planeness of basic unit's face, owing to adopting method of attaching, work progress labor intensive and time, high-altitude construction operation can cause potential safety hazard, and post processing work trouble, warming plate also cannot recycle, and in a lot of large-scale conservancy concretes dam, is difficult to actual applying.
Summary of the invention
The object of the invention is to for overcoming the deficiencies in the prior art, a kind of severe cold cold weather concrete dam insulation quilt and mounting method and erecting device are provided, in meeting insulation quilt heat insulation effect, by the improvement to installation measure and device, insulation quilt installation effectiveness is improved greatly, avoid high-altitude construction operation, the later stage removes convenient and swift equally, and insulation quilt and fastening devices all can recycle, avoid causing unnecessary waste.
For realizing object of the present invention, the present invention has adopted such technical scheme:
First, to improving for the insulation quilt on severe cold cold weather concrete dam, change the insulation construction that traditional employing is pasted, be the grooved tracks of a group and be provided with two on the dam facing of concrete dam, the insulation quilt of concrete dam is located between two grooved tracks, and grooved tracks can block the two ends of insulation quilt make insulation quilt to slide up and down along this grooved tracks; The two ends of insulation quilt connect an active connection, and this active connection can be inserted in described grooved tracks and be blocked and can slide up and down along grooved tracks.Insulation quilt is dragged and is slided up and down by grooved tracks after launching like this, covers thereby realize the covering to dam facing or remove.Preferably, grooved tracks symmetrical pre-buried be fixed on concrete dam need covering and heat insulating the both sides of dam facing part.Grooved tracks raises and extends with concrete dam, and the covering and heat insulating of dam facing can be synchronizeed and carry out with the construction of dam body main body like this.
Preferably, active connection is special-shaped fastener, and its one end can be connected with the edge of insulation quilt, and the other end is stuck in described grooved tracks.As a kind of possibility, active connection is T-shaped fastener, and grooved tracks is provided with the semi-enclosed U-shaped groove that can block T-shaped fastener.Being provided with the inside outstanding baffle part from both sides in the open side of U-shaped groove blocks T prefix portion two projections of T-shaped fastener.
Therefore, the mounting method of this insulation quilt, its basic step is like this: need the both sides of the dam facing part of covering and heat insulating that two grooved tracks are set at concrete dam, the two ends of insulation quilt connect an active connection, and this active connection can be inserted in described grooved tracks and along grooved tracks and be slided up and down; By drag the dam facing realization insulation of insulation quilt rapid Cover concrete dam after insulation quilt is launched by active connection and grooved tracks; And insulation quilt connects in grooved tracks by active connection or takes off, and realizes recycling of insulation quilt; Grooved tracks is built and is risen and synchronous lengthening rising with dam body, realizes the synchronous of dam construction and dam facing insulation.
And for insulation quilt is laid along grooved tracks at dam facing, the present invention has also adopted such device: be provided with a roller assembly at dam crest, this roller assembly comprises roller bearing and support, roller bearing is on support, and support is fixed on dam crest, roller bearing can roll on support, preferably can ball realization be set at support and roller bearing place, ball sleeve, on roller bearing, and is fixed on ball on support.Insulation quilt is wrapped on roller bearing, and warming plate is wound around as coil paper, and its termination is exposed at outermost one deck, and therefore outermost one deck of insulation quilt is sagging and be connected with two grooved tracks dam facing by active connection from the dam facing of concrete dam; Insulation quilt is transferred the dam facing part between two grooved tracks on oversite concrete dam along grooved tracks by roller bearing.The two ends of roller bearing are respectively provided with one for limiting the circular baffle plate of described insulation quilt to both sides skew, prevent from occurring being offset when insulation quilt from dragging in grooved tracks.Roller assembly is also provided with at least one artificial rocker part or the motorized motions parts that can drive roller bearing to rotate.No matter the namely parts for driving roller bearing to rotate, adopt artificial or motor driving, is not difficult to realize according to conventional prior art.
In the present invention, should be fixed in advance dam facing for the grooved tracks of fixing insulation quilt, insulation quilt both sides are connected with active connection, active connection is placed in groove, so just make insulation quilt obtain well fixing, play a very good insulation effect, and along with the raising and can increase at dam crest the length of grooved tracks, active connection and insulation quilt gradually of dam body, so just avoid more work high above the ground task.In the time not needing insulation quilt, can at the bottom of dam crest or dam, directly insulation quilt be extracted out from grooved tracks, and can not destroy insulation quilt.
Owing to having adopted technical scheme of the present invention, make the easier for installation quick of insulation quilt, when avoiding more work high above the ground, the heat insulation effect of insulation quilt is greatly improved, and insulation quilt and fastening devices can recycle, therefore this mounting method can make insulation quilt recycle and be not fragile, also makes concrete reach good obturation effect simultaneously.The technology of the present invention measure technical risk is little, simple, convenient and practical, take full advantage of the feature that insulation quilt combines with grooved tracks, not only with low cost, recovery utilization rate is high, to avoiding the laminating of dam body and insulation quilt closely not cause that heat insulation effect is not good plays good effect, be worthy to be popularized.
