Background technology
At present, oblique orthogonal is widely used in the Long Span Roof Structures public building bases such as highway bridge, port and pier, offshore drilling platform, high-filled embankment, high tower structure, super highrise building, pattern foundation pit supporting structure, basement process, large-scale electric power line pole tower and airport, stadiums, recreational and sports activities center, exhibition hall for a clump of piles.Although recent domestic has carried out some Pile-soil-structure Dynamic Interaction model investigations, and achieve more achievement in research, but these researchs are all carried out for vertical single pile or a vertical clump of piles, corresponding experimental model is vertical single pile experimental model or vertical clump of piles experimental model, yet there are no the documents and materials of oblique orthogonal for group's Pile-soil-structure Interaction experimental model both at home and abroad.
In order to study the force and deformation characteristic of oblique orthogonal for group's Pile-soil-structure Interaction system, in project of national nature science fund project (numbering: under subsidy 41372288), intend adopting similar simulation experimental method to carry out correlative study, but because oblique orthogonal makes complicated for group's Pile-soil-structure Interaction experimental model, so that still lack the similarity simulation experiment model matched at present, therefore, need a kind of effective tiltedly orthogonal of utility model for group's Pile-soil-structure Interaction experimental model.
Summary of the invention
The purpose of this utility model is to provide a kind of tiltedly orthogonal for group's Pile-soil-structure Interaction experimental model, this experimental model not only can reflect the interaction property of oblique orthogonal for group's pile-soil-structure system really, and structure is simple, cost of manufacture is cheap, practical, Technological Economy is feasible.
Technical solution adopted in the utility model is: tiltedly orthogonal is for group's Pile-soil-structure Interaction experimental model, and it is made up of for multi-column pier foundation, cushion cap and superstructure native case, foundation soil, tiltedly orthogonal; Described native case is the hollow cuboid that top is opened wide, and is formed by Plate Welding; Described foundation soil is divided into two-layer, and upper strata is clay, and lower floor is sand; Described oblique orthogonal is made up of two plumb piles and two raked piles for multi-column pier foundation, and at the bottom of stake, absolute altitude is identical; Described cushion cap is the cuboid of concreting, and plumb pile and raked pile connection are entirety by it; Described superstructure is made up of Single column pier and counterweight, and Single column pier is cylinder, and two vertically disposed threaded rods are implanted in upper end, and counterweight is combined by the counterweight of Different Weight.
Construction usage method of the present utility model is: tiltedly orthogonal is for group's Pile-soil-structure Interaction experimental model, first, according to the prefabricated overall structure be made up of for two plumb piles in multi-column pier foundation and two raked piles, cushion cap and Single column pier oblique orthogonal of design size, and implant two vertically disposed threaded rods in the upper end of Single column pier.Then, native case is welded according to designing requirement with steel plate, and the sand filled out in native case in foundation soil, when at the bottom of the depth of fill reaches during absolute altitude, the prefabricated overall structure be made up of for two plumb piles in multi-column pier foundation and two raked piles, cushion cap and Single column pier oblique orthogonal is placed to the top of foundation soil by designing requirement, then continues back-up sand soil, when the depth of fill reaches the design elevation of sand, start to fill out clay, until the depth of fill reaches the height of designing requirement.After experimental model completes, the load of experimentally required superstructure, chooses the counterweight of the Different Weight required for counterweight, and is placed to by the counterweight chosen on the threaded rod of Single column pier upper end, add Upper gasket, fastening nut.Finally, experimental requirement, carries out loading experiment to oblique orthogonal for group's Pile-soil-structure Interaction experimental model, and records relevant experimental data.
Operating principle of the present utility model is: tiltedly orthogonal is for group's Pile-soil-structure Interaction experimental model, it is the reduced scale experimental model be made according to the pre-determined likelihood ratio, the composition structure of this experimental model is all consistent with Practical Project with stressing conditions, therefore, can reflect that in Practical Project, oblique orthogonal is for the force and deformation characteristic of group's Pile-soil-structure Interaction system really.
The beneficial effects of the utility model are: tiltedly orthogonal is simple, easy to make, cheap for group's Pile-soil-structure Interaction laboratory model construction, engineering practicability is strong, and can comprehensive and accurate simulation Practical Project situation, gained result of study truly can reflect the mechanical state for group's Pile-soil-structure Interaction system of oblique orthogonal in Practical Project, thus provides necessary Data support and construction to instruct for the theory analysis of Practical Project, engineering design and site operation.
