Supporting mechanism includes pedestal, one level of support bar, secondary support bar and several sections of push rod, wherein one level of support bar is located on pedestal, secondary support bar is plugged in one level of support bar, the top of one level of support bar is provided with connecting hole, the lower end of secondary support bar is provided with several adjustment hole, one level of support bar and secondary support bar are fixed by connecting hole and adjustment hole and are connected, the height of secondary support bar is regulated by the adjustment hole of secondary support bar bottom, push rod is located at the top of secondary support bar, and the upper end of push rod is resisted against bottom the steel cofferdam of the first order.
The material of base plate, guide rail, pedestal, one level of support bar, secondary support bar and push rod is steel.
The syndeton of one level of support bar and pedestal and pedestal and base plate is demountable structure.
The outside of the steel cofferdam joint of adjacent level is pasted with PVC waterproof film.
Use principle of the present utility model:
According to the depth of water and go along with sb. to guard him area determination steel cofferdam progression and steel cofferdam diameter at different levels, go along with sb. to guard him the number of area and shape determination supporting mechanism according to cofferdam.Guide rail is fixed on base plate, steel cofferdam at different levels is connected together, then the steel cofferdam of bottom one-level put into guide rail and carry out being fixed into an entirety, by crane by this overall submerged assigned address, afterwards several grades of steel cofferdams are upwards sling until its upper edge exceeds the water surface, ensure that steel cofferdam at different levels stretches out completely simultaneously.Afterwards each one level of support bar is fixed with pedestal and is connected, then determine that one level of support bar and the corresponding position of secondary support bar use bolt to be fixed connection by connecting hole and adjustment hole according to the height to base plate bottom several grades of steel cofferdams, overall length after one level of support bar and secondary support bar connect slightly is shorter than the height to base plate bottom several grades of steel cofferdams, again by regulating the height of push rod, it is made to contact with bottom several grades of steel cofferdams, remove the power be applied on several grades of steel cofferdams afterwards, the weight of upper end steel cofferdam at different levels is all born by supporting mechanism.Finally drawn water in inside, cofferdam, PVC waterproof film is attached to outside steel cofferdam joint at different levels in pump process, inside and outside cofferdam, mineralization pressure is poor gradually, and PVC waterproof film is tightly attached to outside the joint of steel cofferdam at different levels under the effect of external and internal pressure difference, prevents cofferdam seepage.
The beneficial effects of the utility model:
Steel cofferdam can stretch, and greatly shortens the steel cofferdam installation and removal time used, saves man power and material, accelerating construction progress, shorten the construction period; Each component can be recycled, and service life is longer; Simple structure, easy construction, cost relative moderate; According to the depth of water and go along with sb. to guard him area determination steel cofferdam progression and cofferdam at different levels diameter, according to the number going along with sb. to guard him area and shape determination supporting mechanism, avoid construction waste.
