Abstract
According to large water bearing platform installation at present, a water stopping device is arranged below a preformed hole, cofferdam construction is carried out on the upper portion through steel pouring jackets, and when the depth of water exceeds 30 meters, the construction difficulty of the steel pouring jackets becomes larger along with the increasing of the depth of water. The invention provides a large deepwater prefabricated bearing platform installation device to meet requirements of deepwater bearing platform installation. Water stopping devices are pre-installed below and above preformed holes of prefabricated bearing platforms, and water pumping pipes are buried above the preformed holes of the prefabricated bearing platforms. After the bearing platforms are placed to the designed elevation positions, water in the preformed holes of the prefabricated bearing platforms is completely pumped away, and a manhole is formed in the bottoms of redundant steel pipe piles. The steel pipe piles are connected with the bearing platforms in a welding mode through shear keys, the steel pipe piles are cut off, and the redundant steel pipes are ejected to the tops of the preformed holes of the prefabricated bearing platforms through a hydraulic jack and are fixed through check blocks. Preformed hole concrete is poured, and the redundant steel pipe piles and the water pumping pipes are pulled out.
Description
Technical field
The present invention relates to the prefabricated cushion cap erecting device of a kind of large-sized deep water.
Technical background
Current large-scale underwater support table is installed as preformed hole bottom and establishes antipriming, constructs with steel boxed cofferdam in top, and when the depth of water is above over 30m, steel jacket box difficulty of construction is just along with the depth of water degree of depth increases and strengthens.
Summary of the invention
The needs of installing for solving deep water cushion cap, the invention provides a kind of large-sized deep water cushion cap erecting device.
The technical solution adopted for the present invention to solve the technical problems is, at the bottom of each prefabricated cushion cap preformed hole, top, antipriming is installed in advance, buries drinking-water pipe underground.Cushion cap is put into after design elevation, and water in prefabricated cushion cap preformed hole is drained, and offers one cross manhole in unnecessary steel pipe pile bottom.With shear connector, by steel pipe pile and cushion cap welding, cut off steel pipe pile, unnecessary steel pipe is arrived to prefabricated cushion cap preformed hole top with hydraulic jack jacking, with block, fix.Build preformed hole concrete, extract unnecessary steel pipe pile, drinking-water pipe.
The invention has the beneficial effects as follows, simple in structure, can meet deep water cushion cap needs are installed.
