Abstract
According to large water prefabricated 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. Steel cylinders with the diameter larger than designed steel pipe piles by about 60 cm are pre-installed on the tops of preformed holes of prefabricated bearing platforms, the tops of the steel cylinders are higher than the highest water level by two to four meters, and water pumping pipes are installed in advance. After the prefabricated bearing platforms are placed to the designed elevation positions, water in the preformed holes of the prefabricated bearing platforms is pumped away, and a manhole is formed in the bottoms of the redundant steel pipe piles. Shear keys are welded. The redundant steel pipe piles are cut off, and the redundant steel pipe piles are pulled out. After post-cast strip concrete is poured, and the steel cylinders 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
In current large-scale water, prefabricated cushion cap 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 the prefabricated cushion cap of deep water, the invention provides the prefabricated cushion cap erecting device of a kind of large-sized deep water.
The technical solution adopted for the present invention to solve the technical problems is that the steel cylinder that diameter is greater than design steel pipe pile 60cm left and right is installed in advance at the top of each prefabricated cushion cap preformed hole, steel cylinder top is higher than peak level 2-4m, drinking-water pipe is installed in advance, prefabricated cushion cap is put into design elevation, after drawing water in prefabricated cushion cap preformed hole, in unnecessary steel pipe pile bottom, open one and cross manhole, welding shear connector.Cut off unnecessary steel pipe pile and extract unnecessary steel pipe pile, building after the concrete of ater-casting, extracting steel cylinder, drinking-water pipe.
The invention has the beneficial effects as follows, simple in structure, can meet the prefabricated cushion cap of deep water needs are installed.
