Abstract
The utility model relates to a system for towing and launching of a caisson. One end of a drawstring is connected with an embedded pull ring of the caisson through a joint plate, and the other end of the drawstring fastens an airbag after the other end passes through a drawstring on the airbag, and is connected with the pull ring through another joint plate to fix the airbag. The charging port of the airbag is connected with an air pipe through a quickly-connected plug. The air pipe is connected with an air compressor to charge the airbag. The system uses the buoyancy generated by the airbag to reduce the draught of the caisson. As the moment arm of the buoyancy generated by the airbag is large, the buoyancy moment of the caisson is changed by charging and discharging the airbag, thus adjusting and correcting an error. The system not only is sensitive, but also operated conveniently, quickly and accurately, which ensures the caisson to be launched and towed out of the waterway successfully, thus reducing the construction cost, shortening the manufacturing cycle of the caisson, ensuring the caisson quality and accelerating the process of the overall project.
Description
One, technical field:
Eaves gutter was put the system of caisson and haul caisson under the utility model related to.
Two, background technology:
Flourish fast along with in recent years harbour cause, the coastal cities port construction is like a raging fire, and according to port city geographical position and geologic structure, a lot of harbours adopt this maturation of caisson gravity, stable, structural shape that durability is strong.The process fewer and feweri along with available deep water water front and marine vessel maximizes, the construction of deepwater offshore harbour is imperative.But be subjected to the restriction of traditional caisson precasting yard construction technology, the ways-end depth of water and haul fairway depth, make a lot of engineerings have to adopt the caisson secondary to connect high technology, not only time-consuming, effort, increase engineering cost, and the total quality that influence caisson is controlled.
Through the stability calculation of swimming, the stable drinking water behind the setting-out is 14.6 meters as certain port New Port reorganization and expansion the second stage of the project Type B caisson, and the stable drinking water behind the C type caisson setting-out is 14.88 meters, and because of caisson leans forward, drinking water can reach about 15.3 meters during haul.And the caisson depth of water on way end of caisson precasting yard is-10.0 meters (the port absolute altitude is built in the locality), and the rolling tidal level need be (the port absolute altitude be built in the locality) more than+5.0 meters, but+more than 5.0 meters the time of lasting of tidal level very short, do not satisfy the requirement of caisson towage.Therefore, B, C type caisson can not make its rolling go out caisson precasting yard slideway after integral prefabricated.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of air bag floating aid system is provided, and system is rationally simple, effectively reduces the caisson drinking water, guarantees that caisson descends water smoothly and hauls out the navigation channel.
The technical scheme that the utility model is adopted for achieving the above object is: the air bag floating aid system, drawstring one end is connected by the pre-buried draw ring of junction plate and caisson, the drawstring retaining ring that the other end passes on the air bag is lived air bag, and is connected fixation balloon once more with draw ring by another junction plate.The inflation inlet of air bag is connected with airduct by fast plug, and airduct is connected with air compressor machine, is airbag aeration.
Described draw ring is pre-buried two-layer up and down at reinforced concrete caisson cabinet exterior face.
Described air bag is two-layer about dividing, caisson is arranged on four sides.
Each air bag of described drawstring is arranged three.
The utility model adopts the rubber pneumatic bag floating aid system, the buoyancy that promptly utilizes air bag to produce reduces the drinking water of caisson, because the buoyancy arm of force that air bag produced is bigger, the way that adopts air bag to fill, exit changes the buoyancy moment that caisson is subjected to, and adjusts correction, and is not only highly sensitive, and it is easy to operate, quick and accurate, guarantee that caisson can descend water smoothly and haul out the navigation channel, for the smooth implementation of engineering has won valuable time, and explored the new technology of a launching caisson and haul.By facts have proved, adopting air bag to help the following water of the case that drifts along and haul technology is success fully, solved caisson because of absorb water excessive can't be in the difficult problem of precasting yard monobloc cast moulding, avoided the secondary of caisson to connect height, both reduced operating expenses, also shorten the prefabricated cycle of caisson, guaranteed the caisson quality, accelerated the integrated engineering progress.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Five, the specific embodiment:
Air bag floating aid system as shown in Figure 1, according to B, the concrete characteristics of C type caisson are selected the rubber pneumatic bag 1 of 2.5 meters and 2.0 meters two kinds of diameters for use, every group of air bag divides two-layer totally 8 up and down, caisson 9 four sides are arranged, 4 every layer, the effective length of rubber pneumatic bag is 9 meters and 7 meters two kinds, the air bag specifications and models are used and are seen the following form, each air bag is arranged three drawstrings 2, the pre-buried two-layer draw ring 3 up and down of reinforced concrete caisson cabinet exterior face, drawstring one end is connected with the pre-buried draw ring of caisson by junction plate 4, and the other end passes drawstring on the air bag and buckles 5 and entangle air bag, and passes through another junction plate and be connected with draw ring once more, fixation balloon, the inflation inlet of air bag is connected with airduct 7 by fast plug 6, and airduct is connected with air compressor machine 8, is airbag aeration.
Carry out typical case's construction of air bag method rolling caisson in 2005, obtained expected effect; With water under the caisson rolling, safety is hauled to construction area smoothly.
During operation, prefabricated (pre-buried air bag the draw ring) → air bag of caisson is customized → air bag on caisson → caisson tidewater such as rolling and setting-out → fixation balloon → wait from slideway reach+more than 3.5 meters the time, the caisson rolling is to ways-end → fixedly enclose cable and towing cable → caisson is hauled out slideway with tugboat.
Before caisson is installed, remove air bag, slowly give air bag deflation gradually, keep the stable of caisson, treat that air bag do not born when helping floating work, air bag is left a small amount of gas, the fast plug of gas tube is removed by water under the diver, untie any one junction plate of air bag, open the drawstring button, utilize the residual gas in the air bag, air bag is floated on the surface, by civilian boat air bag, drawstring are towed back to and to be kept well, treat that operation next time uses.
