Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0010] Such as figure 1 , shown in 2, the pneumatic cement soil sampler of the present invention comprises a lower linkage rotating cover plate 1, a lower positioning lock 2, a swing bar 3, an upper positioning lock 4, an upper linkage rotating cover plate 5, a guide rod frame 6, a fixed frame 7. Cylinder support 8, cylinder 9, moving frame 10, sampling tank 11, guide rod 12, guide wheel 13, etc.
[0011] Guide rod 12 is fixed on fixed frame 7 front both sides through guide rod frame 6. The mobile frame 10 is connected with the guide rod 12 through guide wheels 13 fixed on both sides thereof, and can move up and down along the guide rod 12 .
[0012] The sampling tank 11 is respectively connected with a moving frame 10 up and down, and the upper and lower moving frames 10 are respectively connected with a reversible upper linkage rotating cover plate ...

The invention relates to an air powered soil cement sampler, comprising a fixed frame, a movable frame, a sampling tank and a guide rod; the upper and lower parts of the sampling tank are separately connected with movable frame, a upper movable frame and a lower movable frame are mated and connected with a stator and a guide rod which are arranged on the two sides of the movable frame. A cylinderis connected with the back of the fixed frame, the upper movable frame and the lower movable frame of the sampling tank are separately moveably connected with a upper joint action rotary cover plate and a lower joint action rotary cover plate, a swing link is moveably connected with the upper joint action rotary cover plate and the lower joint action rotary cover plate and the back of the lower joint action rotary cover plate is connected with a cylinder rod; the side of the sampling tank is provided with a upper alignment pin and a lower alignment pin which match the upper and lower joint action rotary cover plates. The invention solves the key problem of sampling grout before the initial gel of in situ cement mixing pile, provides a new practical accessory tool for testing the indexes of various cement mixing piles such as the intensity and uniformity and solves the difficulty of sampling soil cement grout from deep formation, thus having a wide utilization prospect and considerableeconomic benefit.
Description
technical field [0001] The invention relates to a sampler, in particular to a cement-soil sampler used for testing the construction quality of various cement-soil mixing piles and researching the strength of cement-soil in construction and municipal foundation projects. Background technique [0002] The inspection methods currently used usually include static penetration, standard penetration, core drilling (core sample unconfined compressive strength) and single pile load test. But all have the deficiencies of large test result error, low sampling success rate and easy damage to the cement-soil pile or wall used in the project. In order to overcome the above shortcomings, Chinese utility model patent ZL 200620046546.1, 2007.12.12 discloses a cement and soil mixed foundation automatic sampling machine. The inner wall is connected with a bracket and a sleeve bracket, one side of the inner wall is connected with a push plate groove, the top of the push rod is connected with t...
