Description

A kind of viscous soil horizon prepares the model barrel that bury vertical with static pressed pile
Technical field
The invention belongs to pile foundation engineering field, relate to a kind of model bucket assay device, especially relate to a kind of viscous soil horizon and prepare the model barrel that bury vertical with static pressed pile.
Background technology
Research to static pressed pile hammering mechanism, indoor model test is in the majority, and for the ease of operation, almost all uses sand, does not accounts for the fact that in engineering, most static pressed pile are in viscous soil horizon.At present, preparing cohesive soil does not also have the special model bucket of laboratory, and preparing cohesive soil in test chamber wastes time and energy, and significantly limit the research to static pressed pile hammering mechanism.The research of Jacked Pile Driving, key technology therein is how to simulate static pressed pile vertically to bury, and traditional mode of burying is buried direction and position by manual adjustment, and vertically bury low precision.Therefore, indoor model test based on simulation Jacked Pile Driving, the viscous soil horizon model bucket that bury vertical with static pressed pile how developing a kind of water content preparing preferably simulated field conditions bigger becomes a difficult problem.
Summary of the invention
The defect that it is an object of the invention to overcome above-mentioned prior art to exist and provide a kind of viscous soil horizon to prepare the model barrel that bury vertical with static pressed pile, solve the problem that prepared by cohesive soil difficulty, static pressed pile can not vertically be buried that water content is bigger.
To achieve these goals, a kind of viscous soil horizon of the present invention prepares the model barrel that bury vertical with static pressed pile, and agent structure includes model bucket, the first locating guide device, the first positioning and guiding ring, the second locating guide device, the second positioning and guiding ring, visual opening, bottom drain holes, reinforcing bar handle, model rod, the soil body;It is characterized in that: the first locating guide device is arranged on the left side of model bucket, one end is semicircular ring by steel-pipe welding to model bucket left side top peripheral edge, the first positioning and guiding ring, can be turning to model bucket top center with 180 ° of upsets;Second locating guide device is arranged on the right side of model bucket, and one end is semicircular ring by steel-pipe welding to model bucket right hand top outward flange, the second positioning and guiding ring, can be turning to model bucket top center with 180 ° of upsets;Bottom symmetry at model bucket offers visual opening, the wettest by water enchroachment (invasion) by the visual opening observation viscosity soil body, it is ensured that to prepare the viscosity soil body of certain water content;A bottom drain holes is offered, it is ensured that the water in cohesive soil can be discharged by bottom drain holes, it is ensured that water invades wet cohesive soil completely in the bottom of model bucket, until model bottom of the barrel;Model rod extend into soil body surface by the first positioning and guiding ring and the second positioning and guiding ring;Model bucket is close to outer wall and is welded with reinforcing bar handle, and reinforcing bar handle is to lift model bucket.
The a diameter of 800mm of model bucket of the present invention, height is 1200mm;First positioning and guiding ring, the second positioning and guiding ring diameter are 60mm;Visual A/F is 100mm, and height is 100mm, distance model bottom of the barrel 200mm;The a diameter of 20mm of bottom drain holes, spacing is 300mm;The model a diameter of 60mm of rod, height is 750mm;Reinforcing bar handle distance model bucket top 300mm.
It is an advantage of the current invention that: compared with prior art, provide a kind of viscous soil horizon and prepare the model casing that bury vertical with static pressed pile, its simple structure, cost are low, easy to use, effectively raise the efficiency precision buried vertical with static pressed pile prepared by cohesive soil, improve the accuracy of test.
