Drilling bored concrete pile sediment is measured and cleaning device

Technical Field

The utility model relates to a cast-in-place concrete pile construction technical field, concretely relates to bored cast-in-place pile sediment is measured and cleaning device.

Background

The thickness of the sediment at the bottom of the hole of the cast-in-situ bored pile is the thickness increased from the hole cleaning to the sediment layer at the bottom of the hole before the concrete pouring, and is one of the important indexes of the quality of the formed hole. The possible reasons for the sediment generation at the bottom of the bored pile hole include local hole collapse caused by unstable soil around the pile hole, incomplete secondary hole cleaning, contact with the hole wall when the drilling machine is lifted and the hole wall when a reinforcement cage is lowered, and the like, and the over-standard sediment thickness not only can cause insufficient bearing capacity of the pile foundation, but also can generate serious consequences such as excessive settlement of a structure and the like. Therefore, the detection of the thickness of the reinforced hole bottom sediment in the construction process is one of the key measures for ensuring the construction quality of the cast-in-situ bored pile and the bearing capacity of the pile foundation.

At present, the common sediment measuring method for the cast-in-situ bored pile is measuring by a measuring rope, wherein the measuring rope is arranged at the upper end of a measuring device, and the measuring device is in a cylindrical shape or a hammer shape. When the device is used, the measurer is slowly placed into the pile hole through the measuring rope, and the thickness of the sediment at the bottom of the pile hole is measured. During measurement, if the measured thickness of the sediment does not reach the standard, the sediment is also required to be removed. Common methods for removing the slag include, for example, replacing the bottom sediment by circulating the slurry, or removing the slag by inserting a slag removing tool into the pile hole again, thereby reducing the sediment in the pile hole. However, the slurry circulation needs special equipment, the time consumption is long, and the slag removal efficiency is low.
