The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing be described in detail below, but the utility model are not limited to this.
The utility model is the packaging steel cofferdam dykes and dams 15 of a kind of transportation by driving formula, caisson 1 by the series standard open type forms, described caisson has Plate Welding to form, the wide of caisson 1 is 50cm, and long is 200cm, 300cm etc., and caisson 1 Gao Zeying looks position, the cofferdam depth of water and determines, those caissons 1 are arranged side by side, have paddle hole 2 on the Bottom plate of sinkbox 16, and establish rubber cover plate 3 on the paddle hole 2, in order to sealing paddle hole 2.When caisson 1 was marched into the arena or is shifted, caisson 1 inner chamber was anhydrous, caisson 1 such as barge at the water surface by artificial traction to the construction site, after putting in place, manually back down the rubber cover plate 3 of caisson bottom, water namely enters in the caisson 1, caisson 1 sinks, feet 4 embeds in the riverbed soil.Described caisson 1 is the rectangle steel caisson, and four corners of described caisson 1 are provided with vertical angle steel 5, is provided with on described caisson 1 inwall for vertical channel-section steel 6 and the horizontal channel-section steel 7 of strengthening its structural rigidity.Because the sidewall near water 14 of caisson and backwater sidewall 18 are the long side wall, for the better rigidity of strengthening caisson, add again horizontal channel-section steel 7 between sidewall and the backwater sidewall near water, and the minor face sidewall of two adjacent caissons 1 is fixedly connected with through n shape buckle 8, butt seam 17 is coated with rubber fastening band 9 between the long side wall of two adjacent caissons 1 (being sidewall near water and the backwater sidewall of caisson), described rubber fastening band 9 is set in the draw-in groove that is positioned at butt seam two sides, and the length of rubber fastening band 9 equates that with the overall height of steel caisson 1 described draw-in groove is by being arranged on caisson sidewall 14(front side wall near water) on angle steel 10 consist of.So, the packaging confferdam and dyke-dam of transportation by driving formula of caisson 1 series winding growth tens meters (optionally), the packaging confferdam and dyke-dam of transportation by driving formula should stay on riverbank 12 by wooden frame 11 every some rice, generally is that each caisson uses a wooden frame 11 and riverbank 12 to shore.The method shutoff sealing of conventional confferdam and dyke-dam 13 can be adopted in the two ends of the packaging confferdam and dyke-dam 15 of transportation by driving formula, and conventional confferdam and dyke-dam 13 is such as sand pocket confferdam and dyke-dam, earth bag confferdam and dyke-dam etc.After the cofferdam was enclosed well, the cofferdam should exceed water surface 300mm, can extract the cofferdam internal water accumulation out, realized doing operation (still should for the small-size water pumping machine, drawing water depending on cofferdam internal water accumulation situation in the construction).In the cofferdam construction complete after, remove n shape buckle 8, rubber fastening band 9 etc. between steel caisson, extract caisson 1 interior water out or directly use small-sized hook machine (excavator) the hoisting steel caisson 1 of coordinative construction with water pumper, caisson 1 interior water directly flows out from bottom port, and caisson can float displacement.
