Detailed Description
Referring to fig. 1 to 4, the sampler for the TRD cement slurry sample of the underground cemented soil comprises a sampler base 1, wherein the sampler base 1 is cylindrical, a slurry outlet 3 is formed in the bottom of the sampler base 1, the slurry outlet 3 is communicated with the bottom of the sampler base 1 and extends to the lower part of the sampler base 1, and the slurry outlet 3 is in a shape of a circular pipe.
The outer wall of sampler base member 1 is connected with sampler base member pull rod 2, and the length direction of sampler base member 1 is parallel with the length direction of sampler base member pull rod 2, and the connected mode of sampler base member pull rod 2 and sampler base member 1 is integrated into one piece or welding. The cross section of the sampler base body pull rod 2 is semicircular, the back of the sampler base body pull rod 2 is provided with scales 21, and the scales 21 are distributed between the bottom and the top of the sampler base body pull rod 2. The top of sampler base body pull rod 2 is equipped with handle 22, and handle 22 is the semicircle, makes things convenient for the operator to hold.
The inner wall of sampler base member 1 is equipped with slide rail 11, and the length direction of slide rail 11 is parallel with the length direction of sampler base member 1, and the length of slide rail 11 equals with the length of sampler base member 1, and slide rail 11 is the L template that two symmetries set up.
Underground cement soil TRD grout test piece sampler still includes interior stopper 5, with interior stopper 5 be connected interior stopper pull rod 4, interior stopper pull rod 4 and interior stopper 5 connected mode be integrated into one piece or welding.
