Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the scope of this utility model protection.
As Figure 1-5, according to a kind of lock catch type single wall cofferdam described in this utility model embodiment, including being fixed on riverbed and interconnective some side plates, one end of described side plate is provided with snap close head 2, and the other end of this side plate is provided with the lock buckling groove 3 corresponding with described snap close head 2, the two ends of described side plate are provided with water stopping trough 4.
Wherein, described side plate includes side plate 1 and side plate 29；Wherein, described side plate 1 includes that mainboard 6, the two ends of described mainboard 6 are provided with connecting plate 7 in opposite direction；Wherein, described side plate 29 includes that mainboard 6, the two ends of described mainboard 6 are provided with the identical connecting plate in direction 7；Wherein, described mainboard 6 is provided with some reinforcements 8, and between described mainboard 6 and connecting plate 7, is provided with reinforcing plate 1；Wherein, described snap close head 2 is I-steel；Wherein, described water stopping trough 4 is channel-section steel；Wherein, it is provided with waterstop in described water stopping trough 4 and pours microdilatancy pea gravel concreten；Wherein, the bottom in this cofferdam is provided with cushion cap, and described cushion cap is positioned on described riverbed, and cushion cap uses concrete to carry out back cover.
Understand technique scheme of the present utility model for convenience, below by way of in specifically used mode, technique scheme of the present utility model is described in detail.
nullDescribed side plate 1 is L-shaped long limit 3m，Minor face 0.8m，The steel plate of thick 8mm，Bottom is provided with cutting shoe，Two ends are provided with connecting plate 7 in opposite direction，Described side plate 29 is yi word pattern，Two ends are provided with the identical connecting plate in direction 7，Snap close and water stopping trough 4 it is provided with on described connecting plate 7，Snap close is divided into snap close head 2 and the lock buckling groove 3 corresponding with snap close head 2，Connection between side plate，Side plate connects latter two water stopping trough 4 and is spliced into a square hole，Waterstop is put in hole，And after pouring microdilatancy pea gravel concreten in waterstop, can effectively prevent the junction of side plate from seeping water，It is provided with 32b I-steel on the longitudinal direction of described mainboard 6，Channel-section steel it is provided with on horizontal direction，For strengthening the rigidity of entirety，Described back cover concrete is C40 concrete and uses with catheterized reperfusion 2m under water thick，For improving the sealing of bottom，It is welded with twice Three kinds of hors d'oeuvres 40a I-steel as inner support away from cushion cap top 50cm and working water level position，One inner support of working water level position can be used as temporary guide structure.
Time specifically used, first the crawler crane of side plate 50t and the vibration hammer of 120t are clipped monoblock side plate and enters in riverbed along the leading truck inserted to play of inner support, and 2m at the bottom of distance cushion cap, described side plate sets and starts to inhale mud after putting in place, after suction mud completes, snap close head is buckled into lock buckling groove, and put into waterstop in water stopping trough 4, and in waterstop, pour microdilatancy pea gravel concreten, back cover is carried out subsequently by the C40 concrete that catheterized reperfusion 2m under water is thick, after meeting the requirements Deng concrete strength, draw water, and weld inner support, after inner support has been welded, proceed by bearing platform construction.
The main points that should be noted during construction have: whole steel cofferdam about 20cm bigger than dimension of platform, and side plate sets holding vertically；All weld seam kerosene are detected after machining by side plate；Behind inner support of drawing water position, inner support must be constructed immediately, and steel cofferdam deformation is in use monitored after having constructed by whole steel cofferdam.
In sum, by the technique scheme of this novel practical, overall structure is simply, workable, and peace is torn open easily, is conducive to shortening the construction period, and globality is strong, leak few, and reliable and stable, what energy was safe and reliable carries out bearing platform construction；Material consumption is little, and construction cost is low.
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, make any change; every have same as the present application or akin technical scheme, within all falling within protection domain of the present utility model.
