Description
Technical field
The utility model relates to a kind of drilling construction platform, especially relates to a kind of bridge construction and uses the floating drilling platform.
Background technology
Canal river grand bridge master bridge is (the firm structure continuous beam of the prestressed concrete of m of 48+4 * 80+48); And the suitable bridge of the main pier foundation pier of the firm structure continuous beam of this prestressed concrete is to being followed successively by 28# pier～34# pier; Wherein 28# pier and 34# pier are for dividing dividing pier; These 5 main piers of 29# pier～33# pier all are arranged in canal river (being Shui Zhongdun), and are designed to highrise pile cap.During practice of construction, the cushion cap height 5.0m of 29# pier～5 main piers of 33# pier adds platform height 2m, and cushion cap to put into planar dimension be 26m * 19.6m, add the planar dimension 14.2 * 12.2m of platform, and the height of 5 main piers is 67m～69.4m.
During practice of construction, the covering layer of pier is more shallow in the water, does not see the fracture structure phenomenon.The stratum is single, belongs to monoclinal structure, and formation dip is comparatively mild, and main bedding is respectively N30-60 ° of E/4-10 ° of SE.The joint is " X " shape more grows, and is mostly the steep dip horn shape, and joint plane generally is closed form more, and steep candy section joint plane opens more, spacing 1m～3m, and extensibility is better.The riverbed is the U type, and deep water reaches about 22.3m deeply.Wherein, the depth of water 18.5m of 31# pier, geology from up to down is respectively: land pebble that grating is relatively poor and severely-weathered, weak weathered sandstone; The depth of water 20m of 32# pier, geology from up to down is respectively: severely-weathered sandstone, weak weathering mud stone, weak weathering mud stone and sandstone.Simultaneously, 31# pier and 32# pier do not have covering layer.
Because canal river grand bridge master bridge location in the reservoir area, is located in hilly ground, Guangan, Sichuan, be rich Liu Tan power station from 16km place, bridge location downstream, normal pool level is 213.80m before the lock of power station, thereby surpasses just flood discharge automatically of 213.8m.Do not come on the ship dry season, and only ship could come from downstream when flood season level rises, the wide 12m of power station lock, and big ship can not advance.Have only long 31m according to investigations in the reservoir area, the dull and stereotyped ship of wide 6m and high 2m, load-carrying is at 180 tons, thereby can not satisfy the working load needs.In addition, there is the artificial canal of one section width of the channel 7m in the place that Jia Lingjiang River is gone in the canal river, thereby influences marching into the arena of the large-scale ship in Jia Lingjiang River, and the barge more than the 400t that sails into from Chongqing, Wuhan receives the water route to limit into not the canal river.
Floating platform construction base case is the scheme of a comparative maturity, the existing traditional floating platform constructure scheme that is nowadays adopted all be mostly with barge container as carrier, assembly unit beam and gantry walking system in length and breadth on barge.But in the actual use, above-mentioned traditional floating platform construction basis existence receives the big defective of geographical conditions restriction, and undeveloped as water transportations such as reservoir area, Ba Qu, barge container advances when not coming, and this floating platform constructure scheme just can not satisfy construction requirement.
