Description
Technical field
The utility model relates to a kind of waterproof techniques for underwater shake table, and in particular to one kind be suitable for stroke compared with
Greatly, the high performance water proof device of the higher underwater shake table of water level.
Background technique
Earthquake simulation shaking table is to carry out the most intuitive testing equipment of engineering structure Study on Earthquake Dynamic.For bridge, water
Lower tunnel, offshore wind farm and the Water-related Projects structure such as harbour and coastal engineering, seismic response is significant by water environmental impact, has
Necessity considers the influence of water environment during earthquake simulation test.It is domestic to carry out the research of Water-related Project seismic structural response
It is outer to have built several underwater shake tables.Underwater shake table must effectively seal the accurate mechanical equipments such as table top, vibration excitor, prevent
Water body leakage causes mechanical equipment badly damaged in test；And reduce to the greatest extent water proof equipment to vibration table surface movement and
The influence of water environment.Ground motion is moved comprising three-dimensional in seismic process, therefore earthquake simulation shaking table is preferably able to achieve three-dimensional fortune
It is dynamic.Therefore underwater shake table needs effective waterproof technique, under the premise of meeting the movement of table top three-dimensional, guarantees that shake table is mechanical
The safety of equipment.Existing underwater shake table passes through flexible water cloth and realizes waterproof.Waterproof cloth is mostly made of composite material, passes through
Hydraulic pressure is offset in inflation, and realizes that shake table moves using the compression of waterproof cloth after inflation and stretching.It is stretched ability by waterproof cloth
Limitation, existing underwater shake table movement travel are all smaller, it is difficult to effectively simulation seismism.It is necessary to utility models to be suitable for
The underwater shake table waterproof technique of long stroke shake table is realized effectively anti-under the premise of meeting jigging platform three-way movement
Water.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of underwater shake table wader
It sets, carries out effective waterproof under the premise of meeting underwater jigging platform three-way long stroke movement, reduce to shake table movement and water
The influence of environment, convenient for the realization of the underwater shake table of long stroke.
The purpose of this utility model is achieved through the following technical solutions:
A kind of underwater shake table water-tight device, the concrete foundation including shake table and positioned at shake table periphery are described mixed
It is equipped with sliding slot in solidifying earth foundation, the rigid waterproof plate of T font is slidably connected in the sliding slot, the rigid waterproof plate is by first
Splash guard and the second splash guard composition, first splash guard is located in sliding slot and its both ends is equipped with gas tube, and described second is anti-
Water plate is vertical with the first splash guard to connect and stretches out the sliding slot, and the end of the second splash guard is equipped with gas tube；It is anti-positioned at second
The end of the sliding slot of water plate two sides is equipped with support plate, and the support plate is equipped with gas tube close to the end of the second splash guard.
Compared with prior art, beneficial effect brought by the technical solution of the utility model is: can pass through shake table platform
Relative motion between face and splash guard realizes that underwater jigging platform three-way moves freely effective waterproof under state, reduces shake table fortune
The dynamic influence that water environment is generated.Suitable for the underwater shake table waterproof of long stroke.
Detailed description of the invention
Fig. 1 is to face the schematic diagram of the section structure in the utility model specific embodiment.
Fig. 2 is top view cross section structural schematic diagram in the utility model specific embodiment.
Appended drawing reference: 1- sliding slot, the first splash guard of 2-, the second splash guard of 3-, 4- support plate, 5- gas tube, 6- concrete
Basis, 7- gas tube, 8- water, 9- shake table, 10- gas tube
Specific embodiment
The advantages of in order to make the utility model and feature are easier to be understood, with reference to the accompanying drawings and examples to it
Technical solution is described in detail.
As depicted in figs. 1 and 2, the underwater shake table water-tight device in the present embodiment, the surrounding of shake table 9 are coagulation soil matrix
Plinth 6, the middle part of concrete foundation 6 are equipped with sliding slot 1, slidably connect the rigid waterproof plate of T font to provide waterproof in sliding slot 1
Ability, rigid waterproof plate are made of the first splash guard 2 and the second splash guard 3, and the first splash guard 2 is located in sliding slot 1, the first waterproof
The both ends of plate 2 are equipped with gas tube 10 for moving, and it is directly free to slide and ensure close that two contact surfaces may be implemented in gas tube 10
Envelope, anti-water-stop body leakage.Second splash guard 3 is vertical with the first splash guard 2 to be connect, and a part of the second splash guard 3 stretches out sliding slot
1, the end of the second splash guard 3 is equipped with gas tube 7；Second splash guard 3 is connect by gas tube 7 with the table top of shake table 9, is realized
Waterproof sealing does not occur horizontal relative motions between constraint vibration platform table top and the second splash guard 3, discharges vertical relative motion.
The horizontal direction movement of rigid waterproof plate (the first splash guard 2 and the second splash guard 3) is driven by shake table 9, is vertically constrained by sliding slot 1
Without moving.While shake table carries out the movement of vertical and horizontal direction, rigid waterproof plate carries out corresponding horizontal direction movement,
And without vertical motion.Splash guard (the first splash guard 2 and the second splash guard 3) and the relative motion of shake table or sliding slot are disobeyed
By the deformation of gas tube, but slide.Gas tube is similar to the sealing strip between two slide surfaces
It is equipped with support plate 4 positioned at the end of the sliding slot 1 of 3 two sides of the second splash guard, support plate 4 is close to the second splash guard 3
End be equipped with gas tube 5.Realize waterproof sealing by gas tube 5, the first splash guard 2 of release and sliding slot 1 and support plate 4 it
Between horizontal relative motions.During test, the second splash guard 3, shake table 9 table top and support plate 4 between have water 8, other
Region is isolated by the second splash guard 3 and support plate 4 by gas tube 5,7, realizes waterproof sealing；It is anti-by the rigidity of T font
Water plate, gas tube 5 (emission levels to movement and waterproof) and gas tube 7 (release vertical motion and waterproof) achievable shake table platform
The three-dimensional free movement in face 6.Vertical motion and horizontal movement in its bracket all refer to the movement of shake table.T font it is rigid
Property splash guard mass motion be with shake table carry out horizontal movement.Gas tube, which can ensure that, to be slid and is stopped between moving component
Water.There is no bob and weave under effect of water pressure.
The utility model is not limited to embodiments described above.Above the description of specific embodiment is intended to describe
With illustrate the technical solution of the utility model, the above mentioned embodiment is only schematical, is not restrictive.?
In the case of not departing from the utility model aims and scope of the claimed protection, those skilled in the art are practical at this
The specific transformation of many forms can be also made under novel enlightenment, these are belonged within the protection scope of the utility model.
