Description of drawings
Below in conjunction with accompanying drawing and the specific embodiment the present invention is illustrated further:
Figure is the structural principle schematic diagram that a kind of embodiment of device is used in the concrete local defect reparation of middle water level of the present invention fluctuation zone.
The specific embodiment
Referring to accompanying drawing, concrete local defect reparation device in a kind of fluctuation of water table district comprises the hound 5 that template 1, stainless steel expansion bolt 2, a hound supporting disk 3, Screw arbor with nut at both-ends 4 and some can the adjusting rod body lengths.
Above-mentioned template is used for covering concrete defect cavity 11, and periphery is provided with the sealing adhesive tape 6 of water-swellable around the inner plate surface of template, as at the periphery side of offering of above-mentioned template inner plate surface annular groove, in sealing adhesive tape 6 side's of being arranged on annular grooves.Be provided with air vent 7 to be opened/closed at the top of template, may be configured with control valve in order to realize its switching as air vent, when only being provided with air vent, but this air vent double as air-filled pore; Certainly, also have other selection mode, as when being provided with air vent to be opened/closed, also be provided with air-filled pore to be opened/closed.Be provided with injected hole 8 to be opened/closed in the bottom of template, may be configured with control valve in order to realize its switching as injected hole, when only being provided with injected hole, but this injected hole double as drain hole; Certainly also have other selection mode, as when being provided with injected hole to be opened/closed, also be provided with drain hole to be opened/closed.
Above-mentioned stainless steel expansion bolt is used for being fixedly connected centre in the concrete defect cavity, the centre of template is provided with connecting hole, the stainless steel expansion bolt passes the connecting hole on the template, bolt section at the stainless steel expansion bolt that is positioned at the template inboard is rotary with setscrew nut 9, the effect of this setscrew nut mainly is: the fixing position of recovery template, and what guarantee to repair is surperficial concordant; Bolt section at the stainless steel expansion bolt that is positioned at the template outside is rotary with sealing nut 10, and the effect of sealing nut mainly is spillage when preventing slip casting; By cooperating between bolt, setscrew nut and the sealing nut template being fixedly connected in the outside of concrete defect cavity, make template cover the concrete defect cavity fully.
Above-mentioned Screw arbor with nut at both-ends docks with the free end of stainless steel expansion bolt by a branch sleeve 12, and the brace supporting disk is screwed on the Screw arbor with nut at both-ends.The outer plate surface that one end of above-mentioned each hound the withstands on template place that keeps to the side is provided with the thrust jack as the position of the corresponding hound roof pressure of template, and the other end withstands on the brace supporting disk, is provided with the grafting aperture as the brace supporting disk.Certainly, also have other selection mode, the outer plate surface that is hinged on template as an end of each hound place that keeps to the side, the other end is hinged on the brace supporting disk.Preferably, above-mentioned each hound includes two sections bodies of rod, is docking together by No. two branch sleeves 13 between two sections bodies of rod.
Preferably, in aforesaid way, the quantity of hound is the even number root, and per two hounds are made into one group, one group of hound symmetric arrangement, i.e. symmetric arrangement centered by Screw arbor with nut at both-ends; The position of the thrust jack on the above-mentioned template and quantity and hound are suitable.
Its operating principle roughly is:
With the concrete defect cavity be loose part remove clean after, the centre stainless steel expansion bolt of packing in the defective cavity, and the surperficial concordant setscrew nut of an outside and works is installed at expansion bolt is installed template then; After the template position levelling, add a sealing nut in the expansion bolt outside again, the gap between preliminary fixed form and Sealing formboard and the expansion bolt; Connect expansion bolt and Screw arbor with nut at both-ends with a sleeve then.
According to the size of template and the shortest length of hound, the selected position of hound supporting disk (connector) on Screw arbor with nut at both-ends; Each hound is installed and is adjusted sleeve No. two, by hound roof pressure template, impel around the template and entity structure 14 evenly driving fits of surface.
Template is connected suction pump with injected hole and is carried out draining after 24h is installed, and guarantees that air vent is communicated with the atmosphere in the external world this moment; When treating the anhydrous discharge of injected hole, air vent and air pump are connected, be pressed into air by air pump in the concrete defect cavity and check whether template seals; After determining that the no bubble of template periphery is overflowed, close air pump and the concrete defect cavity is communicated with ambient atmosphere, inject repairing mortar by injected hole to the concrete defect cavity.
The slip casting post processing: when mortar to be repaired reached design performance, the mortar that air vent, injected hole are exposed template solidified part and polishes off, stripping then, and the polishing corner, it is suitable to keep repairing position profile circle.And cut off the stainless steel expansion bolt and get final product in the concordant mortar surface of solidifying.
In conjunction with above-mentioned accompanying drawing, a kind of fluctuation of water table district concrete local defect restorative procedure may further comprise the steps:
