Description

Layering mark end device that can wash Technical Field The utility model relates to the technical field of bottom marking devices, in particular to a layered bottom marking device capable of being flushed. Background The layering mark is a device for monitoring ground subsidence, the layering mark bottom is a key component, tiny deformation of ground subsidence is uploaded to a ground monitoring instrument through an internal mark post, and ground subsidence monitoring data are collected. The existing layered mark bottom assembly with the telescopic protection tube is solid in inner rod, in actual work, sediment is often arranged at the bottom of a drilling hole, the mark bottom cannot be placed on a designed target layer, only all mark rods of the layered mark can be lifted, then a drill rod is put into, a large amount of pumps are driven to punch holes, and the efficiency is very low. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a layering marking bottom device capable of being flushed, overcomes the defects of the prior art, and effectively solves the problems of time and labor waste and low efficiency caused by repeated lifting and flushing of sediment in the prior art. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a layering mark end device that can wash, includes the plug rod, the top welded fastening of plug rod has interior target, and the outer wall bottom sliding connection of interior target has the tray, the top welded fastening of tray has outer protection tube, and the outer wall top of outer protection tube cup joints and is fixed with the lantern ring, the top both sides of lantern ring welded fastening has adjusting screw respectively, and two adjusting screw are connected with the spacing ring respectively, the inner wall sliding connection of spacing ring has the bottom inner tube, and the bottom welded fastening of bottom inner tube has the sliding ring, the bottom of bottom inner tube has all pegged graft the backstop with the top of interior target, and the bottom in the interior target is fixed with the contrary subassembly that ends, the contrary subassembly that ends includes solid fixed ring, welded fastening in the mount of solid fixed ring bottom, pegging graft movable in the movable rod of mount center department, welded fastening in the piston at movable rod top, set up between piston and mount and cover and establish the expansion spring on the movable rod wall. Through pegging graft the top of external connection and back joint, make in the flushing fluid got into interior target, when rivers passed through the non return subassembly, the water pressure was stamped the piston downwards, cooperation extension spring's shrink makes the piston keep away from solid fixed ring downwards to open the flushing channel, realized that the flushing fluid is direct through the inside function of pouring into the hole bottom of interior target, when the rivers of below are stamped the piston, the piston can be stopped up in solid fixed ring's bottom, thereby prevent the flushing fluid backward flow.
