Description
Technical Field
The utility model belongs to the technical field of the cofferdam construction, especially, relate to a double-walled steel cofferdam picture peg is anchor structure under water based on finish rolling screw-thread steel.
Background
The steel cofferdam is a water retaining structure for bearing platform construction, the steel cofferdam is generally adopted in the deep water foundation construction of the bridge, and the commonly used cofferdam can be divided into a single-wall cofferdam and a double-wall cofferdam according to the structure. When the steel cofferdam is adopted to construct the underwater pier bearing platform, the steel cofferdam needs to be firstly put down to the riverbed. When the bridge deepwater foundation with slope rock riverbed with large elevation difference change, riverbed with large height-projected pit-depression change, no covering layer or thin covering layer and large fluctuation change of riverbed rock surface is constructed, the bottom of the steel cofferdam can be suspended due to the unevenness of the riverbed surface, in order to ensure that the bottom of the steel cofferdam can be fully contacted and connected with the riverbed, a gap between the bottom of the steel cofferdam and the riverbed needs to be plugged by using the plugboard, the plugboard can furthest reduce the gap between the double-arm steel cofferdam and the riverbed, so that the bottom of a foundation pit of the double-wall steel cofferdam does not need to be horizontal, the blasting and dismantling treatment of high-projection part rocks at the bottom of the riverbed before the steel cofferdam is put down is reduced, even boulders which are difficult to be removed on the riverbed can be allowed, the underwater blasting amount of the foundation pit and the excavation removal amount of the foundation pit are reduced, and the construction amount of, the construction period is saved, and the method is economical and practical. On the other hand, if solve the unsettled problem in steel cofferdam bottom through the blasting excavation depth of deepening steel cofferdam bottom foundation ditch, steel cofferdam overall height also needs corresponding increase to foundation ditch excavation work load increases, can the greatly increased cost like this, and construction cycle is longer simultaneously.
