Description
Technical field
The utility model relates to the underwater shaketalle test technical fields of building, water conservancy etc., are a kind of underwater shake tables
Waterproof construction.
Background technique
With the continuous development that fluid structurecoupling is studied, and works breakoff phenomenon in earthquake of paddling is increasing,
Engineering circles and scientific circles gradually recognize earthquake-hydrodynamic force coupling excitation to the great influence of structural response.For this purpose, earthquake engineering
Analog study, which is gradually gradually converted by single no wate research, to be considered under the hydrodynamisms such as flowing pressure, wave, ocean current
Multi- scenarios method dynamic study.It is water environment that earthquake engineering analog study shake table (array), which is also gradually developed by water-less environment,
Even start to consider circumstance of flowing water.
Due to the limitation of appointed condition, the only analog local vibration of existing shake table, and guaranteed using large-scale actuator
The movement of stage body.This is bound to so that there are biggish gaps between shake table stage body and basis.For that purpose it is necessary to using appropriate anti-
Water measure guarantees stage body during the motion, and test water body will not leak into gap, causes the destruction of mechanical equipment.Currently,
For underwater shake table (array) facility, inflatable waterproof air bag is mostly used, is wrapped between shake table stage body and basis
Gap, and be inflated in gap, so that air bag is heaved.This method structure is simple, but to the seal request on shake table basis
It is higher, and the safe operation of shake table equipment can be seriously threatened if leak occurs for waterproof bag.However, air sac water-proof is being run
It is both needed to inflation in the process to heave, this can occupy the certain volume of test water body, and shake table is in the process of running, the deformation of air bag
It will cause the relatively large disturbances of surrounding body.Therefore, earthquake-hydrodynamic(al) couple of force will cause using air sac water-proof mode to a certain extent
The distortion of quasi- effect is molded, so that test process is influenced, so that test accuracy reduces or test failure.
For this reason, it is necessary to propose a kind of simple shake table waterproof construction of structure, good waterproof effect both can guarantee,

On；Several horizontal actuator are equipped between the concrete foundation and shake table stage body, shake table stage body bottom is equipped with several
Vertical actuator.
Further, the shake table stage body is round or rectangular, the upper layer for bumping table stage body, at each point
Waterproof cloth, lower layer's waterproof cloth section and size remain unchanged；For rectangular shake table stage body, the upper layer waterproof cloth of corner,
Lower layer's waterproof cloth size is slightly larger than side edge, and warp surface is integrally formed.
Further, ribbed stiffener is stalloy or other rigid materials, and guarantees that upper layer waterproof cloth and lower layer's waterproof cloth become
Shape process medium spacing remains unchanged；
Further, upper layer waterproof cloth and lower layer's waterproof cloth length are the 2 of concrete foundation and shake table stage body gap
~3 times；Upper layer waterproof cloth and lower layer's waterproof cloth are all made of water proof geotextiles, guarantee waterproof effect.Every layer of waterproof cloth setting anchoring
Point quantity is 64, is uniformly distributed.
Further, horizontal actuator quantity is 32, and vertical actuator quantity is 8.
The beneficial effects of the utility model are:
A kind of underwater shake table up concave type waterproof construction, it is good anti-guaranteeing to have using double-deck up concave type waterproof cloth
The disturbance effect of water body is reduced under the premise of water effect, and there is beneficial effect outstanding.Structure uses the double-deck recessed waterproof cloth,
Shake table waterproof cloth dilatation in the horizontal direction in the process of running, guarantees the lasting water blocking effect in the shake table course of work
Fruit；Waterproof construction is effectively reduced using up concave type waterproof form and occupies the volume of water body, and prevents take up upper layer test water body, drop
Low disturbing influence of the deformation process to water body；It ensure that waterproof construction is perpendicular in deformation process using ribbed stiffener and connecting hinge
To bearing capacity, so that can be non-inflatable inside waterproof construction；Drainpipe, which is arranged, will can effectively go deep into the water inside waterproof construction
Body is quickly discharged.In addition, waterproof construction design is simple, applicable performance is higher, has good with prospect.

Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Referring to attached drawing 1,2,3, the underwater shake table up concave type waterproof construction of the utility model includes upper layer waterproof cloth 1, lower layer
Waterproof cloth 2, wherein upper layer waterproof cloth 1 is concave form with lower layer's waterproof cloth 2, and length is concrete foundation 7 and vibration
2~3 times of 8 gap of platform stage body.Shake table stage body 8 can be round or rectangular two kinds of structures in the utility model, shake for circle
Platform stage body 8 is moved, upper layer waterproof cloth 1,2 section of lower layer's waterproof cloth and size at each point remain unchanged；For rectangular shake table
Stage body 8, the upper layer waterproof cloth 1 of corner, 2 size of lower layer's waterproof cloth are slightly larger than side edge, warp surface are integrally formed.This is practical new
Type upper layer waterproof cloth 1 and lower layer's waterproof cloth 2 are all made of water proof geotextiles, guarantee waterproof effect.Upper layer waterproof cloth 1 and lower layer's waterproof
Between cloth 2 be arranged 5~10 ribbed stiffeners 3, ribbed stiffener 3 be stalloy or other rigid materials, by connecting hinge 4 respectively with upper layer
Waterproof cloth 1, lower layer's waterproof cloth 2 connect；Ribbed stiffener 3 can maintain biggish vertical rigidity, and horizontal direction can be moved arbitrarily, thus
Upper layer waterproof cloth 1 is effectively ensured to remain unchanged with 2 deformation process medium spacing of lower layer waterproof cloth；Drainpipe is arranged in lower layer's waterproof cloth 2
5, guarantee that the water body under upper layer waterproof cloth 1 leaks can quickly be discharged；Anchoring is respectively set in concrete foundation 7 and shake table stage body 8
Point 6, upper layer waterproof cloth 1 and 2 both ends of lower layer's waterproof cloth are individually fixed on anchor point 6.Every layer of waterproof cloth in the utility model
It is 64 that 6 quantity of anchor point, which is arranged, is uniformly distributed, but be not limited to above-mentioned number, should be to be fixedly secured upper layer waterproof cloth 1 under
Layer waterproof cloth 2, and guarantee that having good waterproofing effect is principle.Between the concrete foundation (7) and shake table stage body (8)
Equipped with several horizontal actuator (9), shake table stage body (8) bottom is equipped with several vertical actuator (10).
In the utility model embodiment, when 8 table top of shake table stage body is square, having a size of 6 × 6m, load-carrying 150t,
Operating depth 3m, horizontal and vertical range 0.5m；Horizontal 9 quantity of actuator is 32, and vertical 10 quantity of actuator is 8；It is mixed
Solidifying earth foundation 7 is 1.5m with 8 gap of shake table stage body；Upper layer waterproof cloth is with the length of lower layer waterproof cloth at minimum clearance
3m, the length at maximal clearance (turning) are 4.5m；Ribbed stiffener vertical extension is 0.5m.
In operational process, horizontal actuator 9 is subjected to displacement with vertical actuator 10 promotion shake table stage body 8 or corner, vibration
Dynamic platform stage body 8 drives upper layer waterproof cloth 1, lower layer's waterproof cloth 2 etc. to be moved by anchor point 6；Due to reinforcement in motion process
The effect of rib 3 and connecting hinge 4, upper layer waterproof cloth 1 and lower layer's waterproof cloth 2 deform (stretching, contraction or displacement etc.), but therebetween
It is constant away from remaining；Since concave form waterproof construction is not in above experimental tank, and water body is tested caused by deforming
11 influence it is smaller, thus during guarantee test water environment true reappearance.
