Further, one end of the steel pipe is welded on the top plate circle center, the other end of the steel pipe is welded with the cover plate at the bottom, and the bottom plate can slide up and down along the steel pipe.
Further, the radius of the cover plate is larger than the diameter of the bottom plate slurry inlet.
The method for extracting the slurry from the bored pile holes with different depths adopts a slurry extractor for extracting the slurry from the bored pile holes with different depths, and comprises the following steps:
(1) The bottom plate measuring rope is tensioned, so that the top plate measuring rope is in a loose state, and the slurry extractor is placed into a bored pile hole to be subjected to slurry extraction;
(2) When the scales of the bottom plate measuring rope reach the target depth, the top plate measuring rope is tensioned to be in a stressed and tensed state, and the bottom plate measuring rope is slowly loosened, so that the bottom plate slowly sinks under the action of dead weight, and meanwhile, slurry enters the inner cavity of the slurry extractor from the slurry inlet of the bottom plate; under the combined action of slurry in the slurry extractor and the dead weight of the bottom plate, the waterproof leather is stretched in place;
(3) Lifting the top plate rope to lift the pulp sampler to the ground;
(4) Pouring the slurry in the slurry taking device into a specified container to finish slurry taking.
The beneficial results of the invention are:
1. the invention has simple structure, low cost and convenient operation, and a user can use the device skillfully through simple introduction.
2. The invention is suitable for the slurry taking operation from the orifice to the bottom of the hole at any depth, and solves the problem that the prior slurry taking device can only collect slurry after the device touches the bottom of the hole.
3. The invention solves the problem that the traditional pulp extractor can not successfully extract pulp due to the strong action of the atmospheric pressure in the cavity.
