Construction method of steel jacket box for rock-socketed bearing platform construction under water level change
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.
本发明创造提供了一种钢套箱用于水位变化下嵌岩承台施工的施工方法，先在设计桥位处岩石中开挖凹槽，然后进行双壁钢套箱的制造、拼装，浮运到现场，在内外侧钢壁板内注入混凝土或者水，使双壁钢套箱下沉到指定位置，根据需要，为增加重力，还可以在双壁钢套箱内壁焊接隔仓板形成隔仓，通过向隔仓注入混凝土或者水，增加重力，满足下沉需要。本发明实施例提供的施工方法与现有技术相比，双壁钢套箱下端不需要设置刃角，不需要采用空气吸泥机，减少设备周转费，减少工程造价，解决了地质条件不适合切土下沉，没有覆盖层或覆盖层少的情况下双壁钢套箱下沉的问题。
