Marking tool and marking method of underground pile position in engineering site

Abstract

The invention relates to a pile position and an underground structure mark. An underground pile position marking tool on an engineering site, the marking tool includes a steel pipe with one end closed: a guide rod inserted from the closed end of the steel pipe with a piston, a marking material tank, which is passed into the steel pipe through a branch pipe, The outlet of the branch pipe is located at the lowest position of the piston. Use sloped steel pipes to take soil from the location to be marked underground and drill holes. After drilling, pour lime or other powdery substances into the marked material tank of the marked position marking tool. The color of the poured material should have obvious color difference from the soil of the project site. Then put the conduit of the tool into the marked hole, hold the handle with one hand, and push the bracelet up and down with the other hand, so that the powder or lime in the lime tank will be sent into the marked hole, when you find the pile position after marking Use a shovel to gently scrape off a layer of the soil surface, and the pile holes will be clearly displayed. The invention prevents pile position marks from being damaged, and prevents field marking piles from causing damage to vehicle tires.

Description

technical field [0001] The invention relates to a pile position and an underground structure mark. Background technique [0002] In the construction of various projects, various pile foundations or other underground structures will be constructed on the site, and there will be cross-construction of various processes during the construction process, and various vehicles in the site frequently travel, and the commonly used piles in the site are in line with the underground The structure is marked as a short pile made of short steel bars or wooden squares. The short pile nailed on the site will be damaged by other construction processes or vehicle running, and will also cause damage to the tires of the vehicle. Contents of the invention [0003] The invention aims at overcoming the defects of the prior art, and provides an underground pile location marking tool and marking method in an engineering site. The invention prevents pile position marks from being damaged, and preve...
