Problems solved by technology
[0005] (1) Due to the more complex construction of the lock joint of the combined steel sheet pile, the connection accuracy is higher, and for the combined steel sheet pile, the lock joint is the weakest
[0006] (2) In the process of driving and pulling, the lock is easy to enter the soil, resulting in the effect of soil accumulation
[0008] (4) The combination of the lock is not tight. During the piling process, the soil enters into it, which will change the stress state of the lock
[0009] Therefore, the protection of the lock is very important, and the existing pile points cannot meet the assembly requirements

Embodiment Construction
[0037] In this embodiment, a recyclable valve-type pile point is combined with figure 1 and Figure 7 , consisting of a pointed body 1, a base body 2 and a bolt 3, the base body 2 is located on the pointed body 1, and the bolt 3 is located on the top of the base body 2, and is used to cooperate with the nut of the steel sheet pile.
[0038] combine figure 2 :
[0039] The tip body 1 is conical and is composed of three identical pile petals, that is, pile valve one 11, pile valve two 12, and pile valve three 13. Each pile valve is composed of one third of conical steel plates;
[0040] The base body 2 is cylindrical, with an outer diameter of 60 mm and an inner diameter of 55 mm.
[0041] The base body 2 is installed on the upper end surface of the tip body 1 through the connection block 4, and the connection between the base body 2 and the tip body 1 is closely attached. In practice, the thickness of the base body 2 is exactly the same as that of the tip body 1, and the T...

The invention provides a recyclable valve type pile tip, and belongs to the technical field of structural components such as foundation engineering special piles or pile shoes. The recyclable valve type pile tip comprises a tip body and a base body, wherein the tip body is of a conical structure, the base body is of a cylindrical structure, the base body is installed on the tip body, the tip body is formed by splicing equant pile petals, and a bearing is fixed in the middle of the base body; the base body is formed by splicing equant valves, and a rail is arranged on the inner wall of the base body; and the pile petals move along the rail, so that the pile petals are folded and unfolded, each valve is connected with the bearing through a connecting rod, and a connecting plate is parallel to the bearing. The recyclable valve type pile tip is applied to installation of steel sheet piles, and has the advantages of being easy and convenient to assemble, convenient to install, recyclable, high in piling positioning precision and the like.
Description
technical field [0001] The application relates to a recoverable flap-type pile tip, which belongs to the technical field of structural components such as special piles or spud cans for foundation engineering. Background technique [0002] At present, steel sheet piles are widely used in the support of foundation pit engineering. According to the production process, steel sheet piles are divided into two types: cold-formed thin-walled steel sheet piles and hot-rolled steel sheet piles. The construction process of the existing steel sheet piles: before the piles are driven in, the grooves at the tip of the piles should be closed to prevent soil from being squeezed in, and the locks should be coated with butter or other grease. When piling, in order to ensure the positioning accuracy and verticality of the combined steel sheet pile, two theodolites are used to observe whether the pile tip is driven into the predetermined position in two directions to control it. [0003] Most...
