Description
Technical field
The utility model relates to a kind of soil nail indoor pull-out test device, belongs to field of experiment equipment, in the indoor pull-out test research that this device is mainly used in geotechnical engineering soil nail.
Background technology
Plate brad supporting is a kind of support form for keeping foundation pit side-wall or stability of slope during soil excavation. Plate brad supporting primarily of in the original position soil body soil nail, bonding soil body surface Steel Concrete surface layer and soil nail between be reinforced the soil body composition, the reactive force such as water and soil pressure and ground additional load can be resisted, thus keep excavation face stablize. A kind of efficient, economic support form conventional in the geotechnical engineering such as Ji Keng, side slope, compared with other Support types, plate brad supporting because of its can Appropriate application soil body self-stable ability, advantage widespread use in geotechnical engineering such as construction is fast, cost is low.
Since plate brad supporting is applied to engineering practice, the research for plate brad supporting system mechanism lags behind engineering practice always, therefore also result in the generation of a lot of accident. Studies in China plate brad supporting common method comprises shop experiment, on-the-spot test, numerical simulation and theoretical analysis. In shop experiment, the indoor drawing experiment of soil nail is a kind of important research method of research soil nail serviceability and plate brad supporting mechanism. And in pull-out test process, how controlling drawing speed, the size obtaining many group soil nail drawing forcies in real time is a difficult point.
Summary of the invention
The utility model provides a kind of indoor drawing experimental installation of soil nail, and this draw-off gear can not only control drawing speed, and can measure many group soil nail drawing forcies in real time simultaneously.
The utility model solves the technical scheme that its technical problem adopts: adopting angle steel welding support, bracket cross section width is not less than trial model case width, and guide rail length is not less than the drawing length required for soil nail, and bracket cross section length is not less than guide rail length; Guide rail is arranged on the attached guide rail angle steel of support, and the slide block on guide rail can be free to slide along guide rail; Square steel pipe is fixed on slide block, and presses desired spacing on square steel pipe and connect electronic dynamometer; Power-equipment is arranged on the attached power-equipment channel-section steel of support, power-equipment circuit and rate control equipment connection; The power-equipment top runner centre of form and the tubular heart of square bar, the electronic dynamometer centre of form are contour, runner and square steel pipe are linked up with and is connected by steel strand.
The beneficial effects of the utility model are: can control drawing speed in drawing soil nail process, and obtain many group soil nail drawing forcies in real time;Testing apparatus is simply efficient, is easy to operation.
