The invention provides a construction method of a steel jacket box for rock-socketed bearing platform construction under water level change. The construction method comprises the following steps thata groove is dug in rock at a designed bridge position, a double-wall steel jacket box is manufactured, assembled and floated to a site, concrete or water is injected into inner and outer side steel wall plates to enable the double-wall steel jacket box to sink to a specified position, according to requirements, in order to increase the gravity, a partition plate can be welded on the inner wall ofthe double-wall steel jacket box to form partition bins, concrete or water is injected into the partition bins, the gravity is increased, and the sinking requirement is met. Compared with the prior art, the construction method has the advantages that a blade angle does not need to be arranged at the lower end of the double-wall steel jacket box, an air suction dredger does not need to be adopted,the equipment circulating cost is reduced, the construction cost is reduced, and the problem that the double-wall steel jacket box sinks under the condition that geological conditions are not suitablefor soil cutting sinking, no covering layer or few covering layers is solved.
Description
technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a construction method of a steel box used for the construction of a rock-socketed cap under changing water levels. Background technique [0002] Steel casing is a common method for bridge foundation construction, and it has been widely used in bridge construction in recent years due to its advantages of fast construction speed, low cost, and high safety. However, in the actual construction process, when the geological conditions are not suitable for the subsidence of the steel casing, the construction advantages of the steel casing cannot be fully utilized, and the safety and reliability are difficult to guarantee, especially when there is no covering layer or In the case of less covering layer, the steel box is prone to subsidence, and the rise of the water level in the flood season will lead to the impossibility of construction. Therefore, it is necessar...
