Slurry sampling device used for detecting TRD equal-thickness cement stirring wall
The invention belongs to a slurry sampling device used for detecting a TRD equal-thickness cement stirring wall and belongs to the field of foundation pit engineering. The slurry sampling device comprises a slurry taking barrel, a piston, a pull rod, a unidirectional locking device, an outer sleeve and a spherical check valve; the barrel top of the slurry taking barrel is hollow and the barrel bottom of the slurry taking barrel is tapered and is provided with the spherical check valve; the barrel top at the upper part is fixedly connected with the outer sleeve by a connecting rod; the piston is located in the slurry taking barrel; and a piston outer ring is in dense contact with the slurry taking barrel by a rubber sealing ring so that the air tightness is good. The pull rod connected with the piston is arranged in the outer sleeve, and the piston is lifted by the pull rod. The unidirectional locking device is arranged on the outer sleeve, and the unidirectional locking is carried out in a pull rod lifting process. The slurry sampling device has the advantages that the design is simple and reliable, the engineering detection cost can be reduced, the construction is convenient and the practicability is strong.
