Sampling system for engineering supervision

Abstract

The application relates to a sampling system for engineering supervision. The sampling system comprises a base, and a mounting groove is formed in the base; a mounting hole is formed in the inner wallof the mounting groove; a sampling mechanism is slidably connected into the mounting hole; a rubber pad is mounted on one end surface of the base; a cavity is formed in the rubber pad; the cavity isfilled with macromolecule nanometer memory glue; through holes are formed in the two sides of the rubber pad; a rubber sheet is fixedly connected to the inner wall of the through hole; a through holeis formed in the rubber sheet; the end face, away from the base, of the rubber pad is coated with a glue layer. One end of the base is abutted against a cement woven bag to be sampled; the sampling mechanism penetrates through the mounting hole and the through holes and is inserted into the cement woven bag; after a sample is taken, the sampling mechanism is pulled out, after the sampling mechanism is pulled out of the through hole, and the macromolecule nanometer memory glue in the inner cavity of the rubber pad blocks the through holes; meanwhile, the rubber pad adheres to the outer wall ofthe cement woven bag under the action of the glue layer, completeness of the cement woven bag can be guaranteed after sampling is completed, and cement waste is reduced.

Description

technical field [0001] The application relates to a detection device for engineering supervision, in particular to a sampling system for engineering supervision. Background technique [0002] Cement sample collection is an important supervision work in project supervision. According to the relevant technical standards and regulations of our country, the collection of cement samples with the same number is based on the same manufacturer, the same grade, the same variety, and the same batch number. One batch shall be no more than 200t in bulk, and no more than 500t in bulk shall be taken as a batch. Each batch shall be sampled no less than once. 12kg. [0003] In the prior art, the Chinese patent document with the authorized announcement number CN206772631U discloses a bagged cement sampler for engineering supervision, including a pointed tip, located at the front end of the sampler, including a conical top facing the front of the sampler and facing the inside of the sampler....

Problems solved by technology

Since the cement on the construction site is usually stacked, after the sampling bucket is inserted into the bagged cement, there will be a hole in the bagged cement. Under the pressure of other cement bags, the cement will fall from the hole to the ground, causing cement waste of
