Abstract
A modular caisson for use in performing underwater tasks in a dry environment includes a plurality of interconnected modules. The end of at least one of the modules is equipped with an end cover through which piping or other equipment can be passed into the caisson without leakage of water into the caisson. In a preferred embodiment, the end cover includes flexible doors. The caisson can be supported by a transport vehicle, or it can be anchored to piles by means of guides formed on the outside of the modules. As a result, the caisson can be prevented from exerting undesirable loads on the piping or other structure being worked upon inside the caisson.
Claims33
A modular caisson for underwater tasks comprising:
- a plurality of interconnected modules, at least one of the modules having an end and an end cover installed on the end, the end cover including an opening through which an object to be worked on inside the caisson can pass and sealing means for forming a watertight seal between the end cover and the object.
A modular caisson for underwater tasks in a dry environment, adaptable to structures, equipment or piping partially or totally submerged in water, comprising a plurality of interchangeable modules that make it possible to vary the dimensions and geometry of the caisson, the modules having side covers where two-part flexible doors are located that permit the passage of an object to be worked upon inside the caisson and that subsequently are joined together by means of watertight and structural toothed racks.
