Description

Pile hole bottom mud sampling device

Technical Field

The invention relates to the technical field of civil engineering, in particular to a pile hole bottom mud sampling device.

Background

With the continuous development and progress of civil engineering technology in China, the types embodied in civil engineering are also continuously diversified, mainly the development of industries with standardization such as bridges, roads, buildings and the like, in order to ensure that the construction technology of bridges and roads in China can be safely and effectively carried out, new high requirements are continuously provided for the construction technology, and technicians of bridge and road construction must continuously master the structural technology of bridges and roads in construction to accurately calculate the stability coefficients of the bridges and roads.

No matter in bridge or road construction, a link is indispensable, that is to have a process of taking a sample to basic unit bottom concrete in the operation basic unit of pouring the concrete, and the purpose is in order to detect each index content and the parameter of basic unit bottommost concrete, confirms whether data can reach the standard.

In a certain construction site or environment, underground or underwater sludge is sampled, samples are extracted from a position which is a few meters under the underwater or sludge for data analysis, and technical conditions such as whether the samples contain other impurities or whether deep excavation can be continued are obtained.

In a word, in the construction, when going on data analysis to the liquid sample that will extract deeper layer or bottom under the environment that has certain degree of depth, the steel drum structure that most all adopted at present is certain cavity shape, put into the environment that is detected earlier to this steel drum, along with this well-done steel drum is continuous to sink, when sinking into certain degree of depth, a aperture will be opened to the steel drum, liquid object on every side will flow into the steel drum through this aperture in, has accomplished and has promoted out the purpose that reaches the extraction underground sample.

However, in the process, the steel drum has a certain volume, that is, the inside of the steel drum has a certain space, so that the problem exists that once the design of the space mode is adopted, the steel drum encounters buoyancy of liquid in the sinking process, the whole steel drum encounters obstruction in the sinking process, the steel drum cannot easily sink to a specified depth even under a deeper liquid environment, and the steel drum possibly enters the liquid in the current layer at any time in the sinking process, so that the measured data of the extracted sample cannot be accurate in any situation, and the side of the liquid in the lower layer is misjudged, and the immeasurable loss and payment are caused.
