Then, after the installation is completed, circular steel plate is separated with first segment drum structure for first segment caisson foundation structure；Again
It is secondary, circular steel plate is connected with the second pitch circle barrel structure, forms the second section caisson foundation structure, the same manner is sunk to installing
In place, and so on the caisson foundation structure for installing other joint numbers, until reaching design requirement.
The working principle of the utility model are as follows:
It is connected by circular steel plate with more piece drum structure, the small-sized caisson foundation structure of more piece is become, in interior external pressure
Sink to installing section by section under difference effect.This mode can effectively reduce drum structure sediment unevenness caused by uneven strata with
The problems such as there are air inside staving enduringly improves caisset foundation stability, efficiently reduces caisset in weakness
The buckling deformation on stratum；Also, original caisset structure length is reduced, certain flexibility is made it have, can effectively fit
The unfavorable geological conditions such as weak sea bed are answered, there is controllability.
The utility model has the following beneficial effects:
1. being connected by circular steel plate with more piece drum structure, the small-sized caisson foundation structure of more piece is become, inside and outside
Sink to installing section by section under differential pressure action.This mode can effectively reduce the unevenness of drum structure sediment caused by uneven strata
With the problems such as there are air inside staving, caisset foundation stability is enduringly improved, efficiently reduces caisset soft
The buckling deformation on weak stratum；Also, reduce original caisset length (this refers to during transportation, the caisson of single-unit
Structure length is reduced relative to original monolithic construction length), certain flexibility is made it have, weak sea can be effectively adapted to
The unfavorable geological conditions such as bed have controllability.
2. in terms of caisson foundation structural stability: the scope of application of caisson foundation structure can be effectively improved, it is heavy to reduce
Box structure foundation instability destroys, enduringly improves its self-stability energy, the personnel safety during guaranteeing caisset construction and runing
And equipment operation.
3. in terms of severe geological conditions adaptability: breaking too long, plastic deformation bad adaptability of original caisson foundation structure etc.
Deficiency makes it have certain flexibility, can effectively adapt to the unfavorable geological conditions such as weak sea bed, has controllability.
4. construction aspect: suction caisson foundation as marine petroleum exploitation platform Deep Foundation Structure, construction technology at
It is ripe, convenient and efficient.
