Underwater slag removal device for reinforcement pile machining

Abstract

The invention relates to minor-diameter underwater slag removal equipment, and provides an underwater slag removal device for reinforcement pile machining. The underwater slag removal device for reinforcement pile machining is provided with a steel slag blowing barrel and hollow drill rods; the diameter of a reinforcement pile drill hole is less than or equal to 30 cm; the lower end of the steel slag blowing barrel is placed on sediments at the hole bottom of the reinforcement pile drill hole; a steel partition plate for dividing the steel slag blowing barrel into an upper steel slag blowing barrel and a lower steel slag blowing barrel is arranged in a center cavity of the steel slag blowing barrel; the number of the hollow drill rods is two, namely, the hollow drill rod I and the hollow drill rod II; the hollow drill rod I is inserted into the steel slag blowing barrel; the lower end face of the hollow drill rod I is higher than the lower end face of the steel slag blowing barrel, sothat a slag blowing barrel is formed; the hollow drill rod II is inserted into the steel slag blowing barrel; the upper end of the hollow drill rod II stretches out of the steel slag blowing barrel and the ground; the lower end face of the hollow drill rod II is higher than the lower end face of the hollow drill rod I; and the hollow drill rod II forms a slag delivery barrel. The underwater slag removal device has the characteristics of high efficiency, labor saving and time saving.

Description

technical field [0001] The invention relates to small-diameter underwater slag removal equipment, in particular to an underwater slag removal device for reinforced pile processing. Background technique [0002] At present, during the drilling process of the most common underground pile foundations in industries such as highways, railways, bridges, and municipal administration, a lot of sediment will undoubtedly be produced, such as figure 1 As shown, in the prior art, the structure for extracting slag from boreholes with a diameter less than 30 cm is as follows: prepare a sediment tank with a diameter of 23 cm, the height of the sediment tank is 70 cm, the wall thickness of the sediment tank is 3 mm, and the sediment tank is sealed with a 3 mm steel plate; Make a hollow drill pipe, insert the hollow drill pipe into the sediment tank, and its upper end communicates with high-pressure air, and the lower end extends out of the steel plate at the bottom of the sediment tank, the...

[0002] At present, during the drilling process of the most common underground pile foundations in industries such as highways, railways, bridges, and municipal administration, a lot of sediment will undoubtedly be produced, such as figure 1 As shown, in the prior art, the structure for extracting slag from boreholes with a diameter less than 30 cm is as follows: prepare a sediment tank with a diameter of 23 cm, the height of the sediment tank is 70 cm, the wall thickness of the sediment tank is 3 mm, and the sediment tank is sealed with a 3 mm steel plate; Make a hollow drill pipe, insert the hollow drill pipe into the sediment tank, and its upper end communicates with high-pressure air, and the lower end extends out of the steel plate at the bottom of the sediment tank, the distance between the end and the steel plate is 15cm to 30cm, and the high-pressure air passes through The hollow drill pipe blows up the sediment at the bottom of the hole, and the sediment is suspended in the water after being blown up. The suspended sediment falls into the sediment tank after sedimentation, and finally the sediment tank is lifted out. Until the requirements of the design specifications are met; although this method can clean up the sediment, it is time-consuming and laborious to take out the sediment tank several times and put it in again during the cleaning process
