Process of jacking utilizing horizontal trolley of jack for caisson

Номер: CN0101586342A
Принадлежит:

The invention relates to a process of jacking utilizing a horizontal trolley of a jack for a caisson, comprising processes of: taking the horizontal trolley of the jack in position; primary pressurizing the jack; taking a transition carriage of the caisson in position; depressurizing the jack, and then pulling the horizontal trolley of the jack out of a jack pit. The invention adopts the horizontal trolley of the jack to jack, therefore complex process that needs a slide rail and a fixed steel plate and adjustment thereof in traditional technology is omitted, mechanical cooperation is not needed, and a large quantity of requirements of a lifting appliance because of line production and cross operation is reduced; the requirements of high strength construction are met flexibly and rapidly, and safety of appliances and personnel is ensure; difficulty that the caisson is jacked without the lifting appliance is effectively solved due to convenient movement.

Water-filled capsule for caisson transportation and production method thereof

Номер: CN0101713194A
Принадлежит:

The invention relates to a water-filled capsule for caisson transportation and a production method thereof. The capsule for caisson lifting transportation trolleys comprises a top plate, a frame, a bottom plate and a water inlet from top to bottom, wherein the water inlet is arranged on the frame; and the frame is a cube, but the four end corners are cambered transitions for reducing stress, the top end and the bottom end are respectively provided with a chamfer adhesion reinforcing part extending inwards. The production method of the water-filled capsule comprises the following steps of: mixing rubber, making the top plate, making the bottom plate, making the frame, assembling the plates, and installing the water inlet. The four cambered corner angles of the capsule can reduce the stress of the capsule, and can prevent the splitting of the capsule body and water leakage in the water filling lifting process. The adhesion joints between the frame, and the top plate and the bottom plate are ...
