Abstract

The invention provides a cast-in-situ bored pile multi-depth slurry sampling device which comprises a cylinder body, a storage cavity is formed in the cylinder body, a feeding check valve and a discharging valve are arranged in the storage cavity, a slidable piston piece is arranged in the storage cavity, a main shaft rod is further arranged, the piston piece is connected with the main shaft rod, a pulling rope is arranged at the upper end of the cylinder body, and a pulling rope is arranged at the upper end of the main shaft rod. The problem of multi-depth sampling of a pile hole of a cast-in-situ bored pile is solved, the depth of the cylinder body is controlled through the traction rope, sampling operation is achieved by pulling the inhaul cable, full coverage of sampling of slurry at different depths of the cast-in-situ pile can be achieved, the sampling operation difficulty is reduced, and the sampling efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the field of bored pile construction, in particular to a multi-depth mud sampling device for bored piles. Background technique [0002] In the construction fields of highway, railway, municipal administration, housing construction, water conservancy, petrochemical and other construction fields, the construction of bored piles is widely used. The drilling mud of the cast-in-place pile plays the role of consolidating the hole wall, suspending the drilling slag, lubricating and cooling the drill bit. It is necessary to judge the effect of hole cleaning through the performance indicators of the mud to ensure the pouring quality of underwater concrete. The performance indicators of the mud are determined by on-site mud sampling tests at different depths. [0003] The traditional mud sampling method is to use equipment to extract the mud from the bottom of the hole or from the mud overflowing from the orifice, and then use the mud ...
