Detailed description of the invention
Below in conjunction with the accompanying drawings technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1:
Formula prefabricated tubular pile stake core soil sampler is dug in rotation of the present utility model, be based on Traditional Man brushing stake holes earth, laitance on the basis of, rotation is coordinated to dig the use of formula prefabricated tubular pile stake core soil sampler, improve and remove earth, the construction effect of laitance in stake holes, while ensureing that detail design requires, save labour cost, reduce the cost.
As illustrated in fig. 1 and 2, rotation of the present utility model is dug formula prefabricated tubular pile stake core soil sampler and is included: soil blade 6 cut by drilling rod 1, handle 2, wing plate 3, steel thimble 4, steel pile casting 5 and spiral.
Wherein, steel thimble 4 is arranged in steel pile casting 5 by wing plate 3, and steel thimble 4 and steel pile casting 5 are positioned on same axial line;Drilling rod 1 is through steel thimble 4, and handle 2 and spiral are cut soil blade 6 and be respectively arranged on the two ends up and down of drilling rod 1;In drilling rod 1 upper end at least provided with two handles 2;Wing plate 3 is three pieces altogether, and three blocks of wing plates 3 are arranged between steel thimble 4 and steel pile casting 5 in 120 ° mutually;It it is matched in clearance between drilling rod 1 and steel thimble 4.
