The invention relates to the technical field of foundation and foundation engineering, and discloses a mud taking cylinder for collecting mud at the bottom of a pile hole, comprising a steel cylinder, a steel cover plate and a hanging rope. The steel cylinder has an inner cavity, and the collected mud is contained in the inner cavity , the steel cover is located in the inner cavity, the sling is fixed with the steel cover, the steel cylinder has an upper opening, and the sling extends to the outside of the upper opening, which is convenient for users to take; when the sling is tightened, the steel cover seals the upper opening cover to prevent the mud from entering the steel cylinder, and the suspending rope extends to the outside through the upper opening; when the steel cylinder is lowered to the bottom of the pile hole or slot hole, loosen the suspending rope to separate the steel cover plate from the upper opening, and the mud will flow from the upper part. The opening enters the steel cylinder. After the collection is completed, the lifting rope is lifted, and the steel cover plate covers the upper opening, and then continues to lift to pull the steel cylinder up.
Description
technical field [0001] The patent of the present invention relates to the technical field of foundation and foundation engineering, in particular, it relates to a slurry extraction cylinder used for collecting mud at the bottom of pile holes. Background technique [0002] At present, for bored piles or underground diaphragm walls with mud retaining walls, it is necessary to collect and test the specific gravity, viscosity and sand content of the mud at the bottom of the pile holes or slots, but for deeper pile holes, such as tens of meters deep For mud, it is necessary to collect the mud at the bottom of the slot and not mix with the mud above the bottom of the slot. It is always a difficult problem to test its mud index. [0003] In the prior art, there are also some pulp extraction cylinders that can enter the bottom of the slot hole or the pile hole for collection, but there are various problems, but the most serious problem is still during the lifting process in the pile...
