Abstract
The utility model relates to a barrel-shaped foundation dry operation chamber for the underwater maintenance of submerged pipelines, which is composed of a foundation, a maintenance operation chamber and a connecting element. The utility model is characterized in that the foundation is a suction type barrel-shaped foundation; the maintenance operation chamber is a chamber structure composed of a plate shell and beams; the bottom is left with an opening facilitating a pipe segment to be maintained to enter; then the opening is sealed; the top of the chamber has a traffic hole leading to the water surface; water in the camber is emptied, and then the chamber becomes dry environment. The utility model is suitable for maintaining pipelines in middle and shallow water depth; compared with the existing underwater dry pipe maintaining means, the utility model has the advantages of simple structure, low manufacturing cost, convenient operation, offshore transportation, handy sinking and placing of auxiliary devices, and low total cost.
Description
The utility model belongs to the improvement of ocean engineering field, marineline underwater maintenance device structure form.
The underwater dry-type of marineline maintenance so far is to take high pressure REPAIR WELDING mode, damaged section of i.e. excision earlier, erection work storehouse (welding chamber) under water then, form the dry type environment in the working bin behind the high pressure gas of injection and marine site depth of water uniform pressure, repair pipe end then, pipe nipple is installed, is carried out the underwater dry-type welding.The required major equipment of this repair mode has: dry-type working storehouse, saturation diving system, diving are supported lash ship and alignment frame, pipe support and fixed system etc.This kind repaiied the tube side method must be with extraordinary diver, extraordinary welding machine, underwater cutting tool and underwater structure installing and locating instrument etc.Have only several companies can carry out this kind at present in the world and repair the pipe operation, the time is longer, the expense costliness.
The purpose of this utility model be to design a kind of simple in structure, easy to operate, expense is cheap, in being applicable to, the dark marineline underwater dry-type docking facility of shallow water, to remedy the shortcoming of the complicated expense costliness of existing marineline underwater dry-type docking facility.
The technical solution of the utility model: a kind of marineline underwater maintenance is used bucket foundation dry-type working storehouse, by the basis, working bin reaches link span composition therebetween, it is characterized in that said basis is the suction type bucket foundation, said dry-type working storehouse is a plate, shell, the bin structure of beam construction, its top has the access hole that passes to the water surface, its bottom is left and is allowed that the maintenance pipeline enters in the storehouse and gives the osed top opening subsequently, opening is with to wait to repair line sections corresponding, opening is stayed respectively on two sidewalls and base plate of working bin, edge of opening has frame to strengthen, the sealing employing of opening and the water shutoff plate of frame driving fit, the water shutoff plate of base plate opening is an integral type, the water shutoff plate of sidewall opening is an opposite opened, the circular hole that clamping waits to repair pipe end is left in the centre, the sealing of rubber sealing is all arranged in slit between water shutoff plate and the frame and between water shutoff plate pore and the tube wall, so form the environment of isolating with seawater, treat storehouse Nei Shui is found time just to become the underwater dry-type working bin, can wait to repair the cutting of pipeline section therein, pipe nipple is installed and welding operation.
Preceence of the present utility model is: the working bin that 1, has bucket foundation can implement to inflate self-floating towing at sea, and reaches objective enforcement exhaust sinking, and required accessory equipment is simple, significantly saves correlative charges; 2, sink to the dark big wave force of bucket foundation centering, the shallow water in seabed and have stability against overturning preferably; 3, bucket foundation dry-type working storehouse integral structure simple structure, the opening hermetic seal is reliable, and overall cost is cheap.
Be described further below in conjunction with drawings and Examples.
Fig. 1-a is a bucket foundation underwater dry-type working bin structure collectivity scheme drawing (being applicable to the form than shallow water).
Fig. 1-b is that bucket foundation underwater dry-type working bin structure collectivity scheme drawing (is applicable to Intermediate Water Depth's shape
Likes).
