Abstract
The utility model belongs to an improvement of a ballasting and levelling device when a drum-shaped foundation conduit frame platform is installed. The ballasting water-tank device is composed of a pump group, a ballasting water tank, water pipe lines, etc., wherein, the bottom of the ballasting water tank is welded with four conical splicing columns; a splicing socket is put on the top of a conduit frame; the bottom of the pump group module is welded with four circular splicing rods; the splicing socket is put on a bottom layer platform of the conduit frame; the ballasting water tank and the pump group module are connected by a rubber water pipe. The device can be used for increasing initialization such as mud and controlling the inclination of the platform when the drum-shaped foundation conduit frame platform is installed.
Description
The improvement of ballast and leveling equipment when the utility model belongs to the installation of barrel base jacket platform.
Bucket Foundation Platform is a kind of platform of novel concept, and it has replaced the pile foundation basis with barrel-shaped shallow foundation, utilizes negative pressure to carry out offshore construction, avoided numerous and diverse marine guidance piling and pile extension operation, save the engineering time, thereby reduced executive cost, reduced the offshore construction risk.Bucket Foundation Platform is in installation process, and initial penetration into mud is an important stage, and can it is related to barrel base form sealing and sinking smoothly.When especially using barrel base in the neritic area, the lightweight construction of platform own, grounding pressure is little, though adopt thin-wall construction can be added to mud in the bottom of bucket, but because the requirement of stability, the bottom of bucket can not be designed enough thinly, if run into top layer hard place base (as the top layer iron plate sand of Shengli Oil Field neritic area), the basic initial penetration into mud of bucket is still more shallow, might can't form sealing and set up negative pressure.Platform passes through in the process heavy, and the control difficulty that tilts especially after the bucket base is gone into the mud certain depth, only relies on crane barge can't adjust the flat-bed leaning angle.The initial penetration into mud and the control of tilting become the important step that the restriction Bucket Foundation Platform is used.
The purpose of this utility model provides a kind of ballast water tank water device, overcomes above-mentioned difficulties, and the barrel base jacket platform is installed in the area shallow at seawater easily, that the top layer ground is hard.Add water by the pump pack module in ballast water tank water, increase flat-bed construction weight, grounding pressure increases, and initial penetration into mud increases, thereby reaches the condition that negative pressure is set up; Adjust the interior water distribution in each district of water tank by pump pack module and bleed valve, change the flat-bed center-of-gravity position, produce and transfer the square of going all out, guarantee platform heavy passing through in the slant range of permission all the time.
Four cabins that the utility model has the advantages that ballast water tank water are separate, and each cabin is provided with bleed valve, and water distribution is adjustable, but both ballast was added to mud, adjustable again whole flat-bed tilt quantity; Water tank and pump component are two modules, all are plugged on the jacket, and the two connects by rubber tube, and is easy for installation; Platform installs, but piecemeal hang and move water tank and pump pack module, device can reuse.After using this device, the marine set-up time of bucket based platform is short, and construction risk reduces, and development benefit increases.
Technical solution of the present utility model is: it is made up of pump group, ballast water tank water, valve, water pipeline etc., the ballast water tank water bottom is welded with 4 conical inserting columns, plug socket is put in the jacket top, pump pack module bottom is welded with 4 circular shanks, plug socket is put on the jacket underlying platform, and ballast water tank water is connected by the rubber water pipe with the pump pack module; Ballast water tank water is provided with four independently cabins, and each cabin is provided with the bleed valve group and is connected with the bleed off bar; One end of rubber water pipe is connected on the pump pack module, and the other end fixedly hangs on the top, cabin of ballast water tank water with steel rope.
Figure of description:
Fig. 1: a kind of ballast water tank water device elevational schematic view that is used for the Bucket Foundation Platform installation
Description of drawings:
1. ballast water tank water 2. pump pack modules 3. jackets 4. bleed valve groups
5. bleed off bar 6. rubber water pipes 7. inserting columns 8. shanks
9. underlying platform
Now the utility model is further described: press required size, location designing requirement making ballast water tank water in conjunction with Figure of description, the ballast water tank water of subsidiary bleed valve, bleed off bar pegged graft is positioned over the top of jacket, and the pump pack module is pegged graft and is positioned over the underlying platform of jacket; At last ballast water tank water is connected by the rubber water pipe with the pump pack module, an end of rubber water pipe is connected on the pump pack module, and the other end fixedly hangs on the top, cabin of ballast water tank water with steel rope.During marine the installation, put to the seabed with the crane barge platform of slinging, add water by the pump pack module in ballast water tank water, increase flat-bed construction weight, grounding pressure increases, and initial penetration into mud increases, thereby is easier to reach the condition that negative pressure is set up; Adjust the interior water distribution in each district of water tank by pump pack module and bleed valve, water filling in going into the few cooresponding cabin of bucket of mud, perhaps opening bleed valve bleeds off into a part of water in the mud cooresponding cabin of bucket how, change the flat-bed center-of-gravity position, produce and transfer the square of going all out, adjustable whole flat-bed inclination angle guarantees platform heavy passing through in the slant range that allows all the time.Platform installs, and hangs with the crane barge piecemeal and moves water tank and pump pack module, and device can reuse.After using this device, the marine set-up time of bucket based platform is short, and construction risk reduces, and development benefit increases.
