Embodiment Construction

[0016] Such as Figure 1 to Figure 4 As shown, the present invention includes a barrel body 1, a lead wire 2 and a back sealer 3, the lead wire 2 is arranged above the barrel body 1, a bottom plate 11 of the barrel body 1 is provided with a barrel bottom hole 12, and the back sealer 3 includes The bottom cover plate 31 and the stop bar 32 arranged at the bottom of the back cover plate 31 , the back cover plate 31 is arranged in the bucket body 1 , and the stop bar 32 is movably connected with the bottom plate 11 through the bucket bottom hole 12 .

[0017] A sealing ring 33 is sheathed on the bottom cover plate 31 , and a limiting piece 34 is provided at the lower end of the limiting rod 32 . The sealing ring 33 is a rubber ring, which is sleeved on the outer periphery of the bottom cover 31 or arranged below the bottom cover 31 to play a sealing role and prevent the mud from leaking when the barrel is pulled upwards. When sampling the sampling bucket is put down to the botto...

Abstract

The invention discloses an automatic sampling bucket for pile bottom mud, in particular to an automatic sampling bucket for pile bottom mud with simple operation, convenient sampling and high speed. The technical problem to be solved is that the mud at the top of the hole is used for the measurement of the specific gravity of the cast-in-place pile mud, which cannot fully represent the mud at the bottom of the hole. The invention includes a barrel, a lead wire and a bottom sealer. The lead wire is arranged above the barrel body, and the bottom plate of the barrel body Bottom holes are provided, and the bottom sealer includes a bottom cover plate and a stop bar arranged at the bottom of the back cover plate, the back cover plate is arranged in the barrel body, and the stop bar passes through the bottom hole of the barrel and is movably connected with the bottom plate. The present invention after adopting such a technical solution has a simple structure, does not need to measure the height, is convenient to use, and uses corner scraps for processing, thereby saving costs.

Description

[0001] Pile bottom mud automatic sampling bucket. technical field [0002] The invention relates to a sampling tool, in particular to an automatic sampling barrel for pile bottom mud. Background technique [0003] At present, in the construction of cast-in-situ piles, the mud circulation method is used for mud control, and the mud displaced to the top of the hole is generally used for mud measurement. Although the measurement speed of this method is faster, the mud specific gravity measurement cannot fully represent the mud at the bottom of the hole. Contents of the invention [0004] The technical problem to be solved by the present invention is that the mud at the top of the hole is used for the measurement of the specific gravity of the cast-in-situ pile mud, which cannot fully represent the mud at the bottom of the hole, and an automatic sampling bucket for the mud at the bottom of the pile is provided with simple operation, convenient sampling, and fast speed. [0005...
